Operations to carry out on powering

It is obligatory to size the ram in order to access the automatic phase and carry out a machining program. Sizing of the locator axes is a facultative operation. It is advisable when there are doubts as to the correctness of the current locator axes targets. The current targets could be incorrect if an axis was moved in the manual mode when the numeric control was off.

1.1.1

Ram sizing Comply with the following procedure to size the ram:

• • •

press

;

if the ram is up, depress the down pedal to lower it below the zero marks; press the up pedal. If resetting has already been carried out, this operation will achieve manual re-ascent.

The ram moves up until it finds both the zero marks of the optic lines of the two cylinders where sizing takes place. It will now be possible to carry out a program in the automatic mode. To repeat the resetting procedure without switching off the NC:

1.1.2

•

press [ Repeat Sizing ];

•

press the re-ascent pedal.

How to size the locator axes Comply with the following procedure to size the locator axes:

•

press

;

•

press

.

The locator axes move towards the sizing limit switch. Once they have touched this latter, their direction is reversed and, after having released the limit switch, they size on the encoder’s first zero mark.

How to draw a new punch Comply with the following instructions to draw a new punch:

•

press

to display the list of dies or punches;

•

press

again if the list of dies appears;

•

select the required type of punch. The punch can either be drawn completely or the four types of preset punch with fixed measurements can be used. By varying these measurements, the punch is rescaled and re-drawn.

The following types of preset punch are available:

Type 1

Type 2

Type 3

Type 4

Figure 1.3 – Types of preset punch It is advisable to use preset punches if the punch required is similar to one of the proposed types (which have been taken from the catalogue) since it will be less difficult to draw. The punch must be drawn completely if it is not within the categories of preset punches.

Note

Esa/Gv

Remember that punch drawing serves for anticollision controls in relation to graphically drawn workpieces while the bending depth calculation is developed according to the dimensional data of the punch. If it is too difficult to completely draw a punch, the problem can be obviated by using a type of preset punch and attempting to adapt it to the real shape as far as possible by means of the predefined data.

•

press [ENTER] : the next line is drawn in the automatic mode. the line to which the data refer is highlighted and the cursor moves to line length entry field 1.

Continue to alternately enter lengths and angles to form the punch drawing. The more the measurements and angles entered are similar to the real ones, the more the drawing will be correct.

Graphic utilities

When entering lines whose measurement may cause problems, the operator can use a graphic utility that allows the value of the angle to be varied by symbol ±1° and the length measurement by symbol ± 1mm at a time, so that the drawing corresponds to the real punch. The value of the angle is increased by 1° by pressing on the right-hand arrow and decreased by one degree by pressing on the left-hand arrow, while the length value is increased by pressing on the up arrow and decreased by pressing on the down arrow.

Drawing curved lines

As seen in the example, the drawing function also allows curved lines to be drawn. Press the [ Arc] key to move the cursor to the arc data entry window. The curved line corresponding to the data entered will be automatically plotted when length 1 and depth h of the arc are entered.

How to correct the entered data

again if the list of punches appears;

select the required type of die. The die can either be drawn completely or the preset die with fixed measurements can be used. By varying these measurements, the die is rescaled and re-drawn:

Figure 1.9 – Types of preset die available

It is advisable to use preset dies if the die required is similar to one of the proposed types (both square and overturned T shaped dies can be drawn) as it will be less difficult to draw. The die must be completely drawn if it is not within one of the categories of preset dies, if a die with several slots must be drawn, if square slots or pressing slots must be used.

Note

Esa/Gv

Remember that die drawing serves for anticollision controls in relation to graphically drawn workpieces while the bending depth calculation is developed according to the dimensional data of the die. If it is too difficult to completely draw a die, the problem can be obviated by using a type of preset die and attempting to adapt it to the real shape as far as possible by means of the predefined data.

Rolling correction

When rolling is carried out, it is unlikely to obtain a correct bend at the first attempt. This inaccuracy depends on the fact that the angles to bend to achieve the rolling operation are very open (e.g. 170°C) and it is difficult to obtain precise bends with these angles. To achieve a correct rolling operation, measure the difference between the obtained rolling angle and the required one. The difference calculated must be homogeneously divided amongst all the bends.

Example

Supposing that a rolling operation with a 90° angle must be carried out and that 15 bends at 170° must be made. If the obtained result is 112.5°, it will be necessary to proceed in the following way: 112.5 - 90 = 22.5° (difference between the real and theoretic angle) 22.5 / 15 = 1.5° (correction to make for each bend) A 1.5° correction must be applied in the rolling step, which is repeated 15 times.

Bending and flattening definition

A bending and flattening operation can be defined in the bend set-up window: enter 0.0 in the Y1 Angle field. The ram’s arrival value will be calculated according to the depth of the slot, the height of the slot for flattening and the thickness of the workpiece. The position of X axis will be at the minimum target the axis can reach. R axis is positioned by taking into account that the die is open.

Bending and flattening correction

If a bending and flattening operation must be corrected, the value of the angle cannot be modified. It will be necessary to change the numeric value in the B.D.C. field of Y1. If the bend is pressed too much, this value must be increased. The Y2 Target will be modified as a consequence. Or it will be necessary to proceed in the following way:

• • •

access the Corrections mask by pressing the

key

press the [Corrections Coeff.] key The target entered is added to or subtracted from the B.D.C. of both the Y values and is a data item bound to the machine and not to the program. Press the [ Lose Correc.] key to annul the corrections.

How to carry out a striking or coining operation

Enter a normal bend with the same angle as the tools, but change the force and making any corrections to the bend as may be required, straight in the set-up mask.

Coining correction

Change the bottom dead center point of Y1 and Y2 to correct a coining operation. If coining is too light, the bottom dead center point must be decreased. If coining is too deep, the bottom dead center point must be increased.

Definition of a conical This function allows the “Conical” process to be carried out once special locators have been assembled and X2 axis configured for conical operation. “Conical bending” is bend carried out by an X2 axis installed on the bar of the X1 axis ( incremental type) or two completely independent axes, X1 and X2 ( absolute type) which, to allow the axes to be staggered, moves after X1 has been positioned. Besides this special X2 axis, the locators also have a special profile, which allows the metal plate to be blocked (see figure). The data for making a conical bend can only be entered from the Setup masks and to enter the conical bend, the X2 axis must be enabled for operation in the conical mode (either incremental or absolute). In this case, once the typical data of a normal bend have been entered, the final target of X2 axis will be calculated in the “incremental” or “absolute” mode in relation to the final target of X1 axis. A utility can be activated in the data entry window of the numeric program in order to make a conical bend:

•

in the case of positive phased angles, the final target calculated is X2, or X1 for negative phased angles.

Once a conical bend has been created and the user wishes to change the phase angle or metal plate width, before accessing the angle entry field with the [Conical ] function key, the bend must be cancelled and a new one set up. If this operation is not carried out, the targets generated by the angle entered in the window will be without sense. If modifications have been made to the data of a bend (e.g. metal plate width or thickness, etc.), the targets are not calculated again: X2, X2 Corrections and X2 Recoil. In a conical bend, the support function does not re-calculate the correction on the X2 Correction and X2 Recoil targets, thus the rest/support must be entered first and then the conical bend data.

Definition of a conical rolling operation

To enter a conical rolling operation, go to the first rolling bend and proceed with the conical phase. The targets vary on the first bend as described previously. Nothing is calculated if rolling is applied to a bend with a negative X1.

How to make off-slot bends

In off-slot bends, the end of bend point is in the upper position in relation to the upper die plane. The end of bend target is numerically higher than the theoretic plate crimping target in the general data of the program. The numeric control checks to make sure that the bending cycle targets are valid and requires the following targets to be in decreasing numeric order: •

Top dead center.

•

Speed change target (from version 13.2 onwards, the TDC cannot be lower than the SCP).

•

Target 180 (crimping target).

•

End of bend target (bottom dead center).

The program cannot be executed in the automatic mode unless this order is complied with.

2.14

Esa/Gv

GB

Brief Guide part 2

For off-slot bends, the user must:

Example

•

Directly enter the end of bend value in the Y1 B.D.C. and Y2 B.D.C. fields of the numeric program (the Y1 Angle and Y2 Angle fields will be set to zero).

•

Enter a value in the P.C.P. field of the program’s machining data which, when added to the Theoretic 180 target , gives a higher value than the set B.D.C. values.

•

Enter a value in the S.C.P. field of the program’s machining data which, when added to the Theoretic speed change target , gives a higher value than the theoretic 180 target + P.C.P.

•

Make sure that the Top dead center (T.D.C) in the program steps is higher than the Theoretic speed change target + S.C.P .

Supposing that a program has been setup in which: Speed change target = 132.00; 180 target = 127.00; Bending target (a = 135°) = 124.72; After having checked to make sure that the required end of bend value is 142.35, this value must be entered in the Y1 B.D.C. and Y2 B.D.C. fields. To execute this program, the user must: enter 20.00 in the P.C.P. field: 127.00 + 20.00 = 147.00 > 142.35; enter 20.00 in the S.C.P. field: 132.00 + 20.00 = 152.00 > 147.00.

The accessed window will present a simulation of the workpiece to bend including the lower and upper parts of the bending press, the punch, the die, the stop and the workpiece prior to bending. There are three windows on the right-hand side of the mask. These respectively indicate the number of rotations and overturnings to which the workpiece is subjected in the found bending sequence plus search enabling of the bending sequence with all the solutions. The numeric control searches for the solution by attempting to always maintain the larger part of the metal plate in the operator’s hand. By modifying the calculation criteria, the sequence can be searched amongst all the possible solutions.

If the workpiece is not feasible, the numeric control warns the operator by means of a NO SOLUTION message. In this case, the operator can attempt to calculate by means of the criterion that searches for all the solutions. If there is no possible solution, the operator can attempt to identify the bend that makes it impossible to bend the workpiece. This is done by means of the manual bending sequence search function. Any collisions of the workpiece with the various parts of the machine are indicated by changing the colour at the side of the workpiece that actually collides. The operator must completely force the bending sequence to bend a workpiece even when it is going to collide (when the collision will not damage the metal plate for example). If the workpiece is feasible, the numeric control informs the operator by a Solution FOUND message. The operator can choose amongst the following functions in this window: •

[Stop]: optimizing is interrupted so that modifications can be made;

•

[Continue]: the numeric control searches for a different solution from the one just found. If the operator continues to refuse the proposed solutions, the numeric control will search until there are no other different ones. Once the solutions have terminated, the search will end with a NO SOLUTION message;

•

Press the button to begin automatic cycle execution. This operation allows the locator axes to position. Once the locators have positioned, press the down pedal to lower the ram and make the bend. Once the bend has been made, the ram returns automatically and the locator axes position for the next bend. When the last bend in the program has been made, the automatic cycle starts again from the first bend. The calculations made by the numeric control are purely theoretic and, owing to imperfections in the metal plate, may need to be corrected. To simplify the way the bending data of a workpiece are corrected, there is a procedure for making a sample workpiece which is carried out in the SEMIAUTOMATIC mask. If this procedure is activated, step change does not occur at the end of a bend as the cycle remains on the current bend to allow the operator to correct the bending data and repeat the bend that has been corrected. The angle or length of the bend can be corrected step by step or in a uniform way for all the bends.

Correction data entry

GB

The correction data to enter are in mm when it comes to the position of the locator axes and in degrees for the bending angle; the data entered are added to the value in the program. Example: if the bend is closed by 2°, a positive correction value must be entered (+2.0°). If the bend is open by 2°, a negative correction value must be entered (-2.0°). If the length of the bend is less than the required length, enter a positive value corresponding to the difference ascertained in the X1 Corr. field. If the length of the bend is greater than the required length, enter a negative value corresponding to the difference ascertained in the X1 Corr. field; if several corrections are made to the data of the same bend, the last value entered is added to the previous ones. Example: if a bend is initially closed by 3° and, after the correction (+3.0°), is open 1°, enter 1.0° in the angle correction field. In the step correction, the angle correction data are separate per cylinder. The Y1 angle can therefore be corrected differently from the Y2 angle; in the general correction, the bending angle is the same for both cylinders. The entered values overlap if a step correction and a workpiece correction are made in the same step. Example: if a -2.0° step correction and a -1.0° workpiece correction are made, the angular correction for that step will be -3.0°. Once the correction data have been entered:

This parameter will be used for calculating the stretch for all the bends entered after the coefficients are modified and for all the new programs. The angle must be re-entered in each bend order to apply the corrections to the existing programs. The default value of the coefficients is 1. The standard stretch is calculated with this value, re-processing the DIN6935 standard. The value entered in the coefficients is multiplied by the stretch calculated. Thus, entry of value 2 calculates double stretch while halved stretch is calculated if value 0.5 is entered. The tolerated values are between 0 and 9. Up to 2 decimals are allowed.

Autolearning cycle

There are particular conditions in which the bending target calculated by the numeric control cannot be used for making a bend (rounded punches, stamped bends, off-slot bends, etc....). In these situations, it is convenient to use the bending target autolearning cycle which can be carried out in the SEMIAUTOMATIC mask. If this procedure is activated, step change does not occur at the end of a bend but the cycle remains on the current bend to allow the operator to autolearn the required end of bend target. The operator can use several different methods to find the correct end of bend target: •

if the target to reach is higher than the calculated end of bend target, the target can be found by using the pedal alone;

•

if the target to reach is lower than the calculated bend target, the operator must enable the Re-ascent to TDC with ascent enabling input, release the pedal at the end of bend target and use the and buttons, which allow the ram to move up or down by a tenth of a millimeter at a time.

Introduction

Types of data

5.2

There are certain categories of data of fundamental importance for operation in Esa/Gv’s S530 numeric control for bending presses: •

Configuration parameters of the machine (Menu 2)

•

Axes parameters (Menu 1)

•

Work programs (graphic or numeric)

•

Fixturing (punches and dies).

Memory devices These data can be stored in the following memory devices: ù

5.2.1

•

Buffered RAM

•

SSD (Solid State Disk) Flash Hard Disk

•

USB Key.

Internal memory (buffered RAM) This is the memory device of the numeric control (that resides on the MULTIFUNCTION board) into which all the machine data are downloaded before being used. Thanks to the battery, these data are also maintained when the numeric control is off.

5.2.2

SSD (Flash Hard Disk) This is the storage device that contains a copy of the operating system, the Kvara application program and its Backup copy, plus the data saved by the Kvara application program (machine data, fixturing programs).

5.2.3

USB Key This is a normal USB Key. It is used for saving the machine’s configuration parameters and for the axes parameters. It is also used for saving the security copy of the programs, punches and dies. The contents of the USB Key Computer.

Recommended security savings

Foreword

Security saving means memorizing the data that allow the bending press to operate on a USB Key.

Parameters

Security saving of the parameters must be carried out at the time of shipment. Any successive modifications must be saved immediately.

Programs

Security saving of the programs must be carried out periodically by the customer depending on the number or importance of the programs he sets up.

Fixturing

Security saving of the fixturing must be carried out after all the tools of a customer have been entered. The customer must save again whenever he enters a new punch or a new die.

5.5.1

Advice for the bending press manufacturer It is advisable to keep:

5.5.2

•

a USB Key containing the machine parameters of each bending press sold (in duplicate or a copy on the hard disk of a Personal Computer);

•

a USB Key containing the fixturing supplied with the bending press.

Advice for the end user It is advisable to keep: •

a USB Key containing a copy of all the machine parameters, fixturing and programs commonly used in the numeric control;

•

a security USB Key identical to the one described above;

•

a copy of the machine parameters in the hard disk of a Personal Computer;

•

a USB Key containing the programs of each individual customer so as to free the greatest amount of memory possible and achieve faster search phases (this USB Key is only required if there is a large number of programs).
