Understanding Key Programming Parameters

A tela principal mostra as dobras disponíveis e, a partir desta tela principal, de cada dobra disponível, parâmetros específicos podem ser visualizados e editados.

The product ID and product description are displayed in the top row on the screen.

Bend Parameters

Each bend in your program can be tailored by adjusting specific parameters such as angle, length, and radius. These adjustments ensure that your final product meets precise specifications.

Bend Methods

1. Curva de ar:
   • Bend to the programmed angle by adjusting the punch depth.
   • Y-axis position is calculated for precision.
2. Bottoming:
   • Sheet pressed between punch and die.
   • Y-axis end position depends on force; limited by calculated position.
3. Hemming:
   • Fold sheet in two after a sharp bend.
   • Y-axis position includes die surface plus twice the sheet thickness.
   • ‘Hem opening’ for Y-axis adjustments.
4. Hemming & Bottoming:
   • Combines hemming with pressing between punch and die.
   • Assumes top of die as Y-axis position.

Note 1: The hemming bends are shown here with a special hemming punch, but this is not required.

Note 2: When bottoming operation is selected, the end of bend position of the Y-axis beam depends on the working force. If however the force is sufficient for the beam to go to the calculated Y-axis end of bend position, the beam stroke will be limited by the position value.

Comprimento de curvatura: Length between tools; crucial for force and crowning calculations.

Effective Bend Length: Used for force calculations; sum of individual bend line lengths.

Product Position: Set the absolute position in the Z-direction starting at the left machine side’s reference zero. This ensures accurate alignment.

Ângulo: Program the required bend angle when angle programming is selected, especially for air bending, to ensure precision.

Abertura da bainha: Determine the opening distance between flanges during hemming. This impacts the beam position calculation and defaults to the Settings mode’s value.

Y-axis (Bend Position): Define the bend’s Y-axis position for absolute programming and methods like bottoming, affecting the bend’s precision.

Mute: Set the point where the Y-axis transitions from fast closing to pressing speed. This is programmable based on the sheet distance or die defaults.

Parallel: Adjust for differences between left and right cylinder sides (Y1 and Y2) to maintain uniformity in bending.

Abertura: Control the gap between punch and die after bending. Adjust this to reduce handling time, either above or below Mute.

Setting Force and Speed

Vigor: Força máxima ajustada durante a prensagem (calculada automaticamente).

Tempo de permanência: Tempo de retenção do punção no ponto de flexão.

Descompressão: Decompression distance after the bending to release the working pressure from the system.

Velocidade: Working speed (pressing speed). Initially, the value for this parameter is copied from the parameter Default Pressing Speed in the Settings mode.

Decomp speed: The decompression speed is the programmable speed of the beam during the decompression distance.

Exploring Additional Functions

Explore the available functions within the DELEM DA-53T programming interface. These functions allow for further customization of your program, enhancing productivity and flexibility.

1. Repetition:
   • 0: Bending is skipped.
   • 1-99: Specifies the number of repetitions for the bend.
2. Wait for Retract:
   • Options to control Y-axis behavior during retract:
     • No: Y-axis moves on, starting retract as it passes the clamping point.
     • Yes: Y-axis halts at clamping point until retract is complete, then proceeds.
3. Code:
   • Manages when new parameter values become active. Options include:
     • 0: Change at end of decompression.
     • 1: Change at muting position.
     • 2: Change at upper dead point.
     • 3: Stop at upper dead point with no axis movement.
     • 4: External signal changes step without beam movement.
     • 5: External signal at upper dead point allowing beam and retract function.
4. Delay Time:
   • Sets delay before step change (0-30 seconds).

Utilizing these parameters in DELEM DA-53T Product Programming optimizes control and efficiency during bending operations.

Add bend

To add a new bend after the last bend. When pressed, the last bend is copied and added after the last bend.

Bumping

From pure numerical programs a single bend step can be changed into a bumping bend.

When Bumping has been selected in the Main view of the DELEM DA-53T Product Programming, a pop-up window is shown where the following parameters can be programmed:

1. Bumping
   • Disabled: Functions as a normal air bend with a defined angle and preferred radius.
   • Enabled: Creates a large radius through different steps of air bending.
2. Ângulo: Specifies the angle value to bend.
3. Raio: Indicates the intended radius to be programmed.
4. Número de segmentos
   • Divides the radius into several segments.
   • Number of bends in the radius equals the number of segments plus one.
   • More segments lead to more precise bends for a smaller tolerance.
   • A higher number of segments requires a smaller V-die opening for proper bending.
5. Segmentos de colisão iguais
   • Computes segment size based on the user-defined number of segments.
   • Standard calculation uses half-size for first and last segments for better results.
   • If die selection for small segments is problematic, equal segment sizes can be calculated.
     • Disabled (no equal sizes): Includes half-size segments.
     • Enabled (equal sizes): All segments are uniform in size.
   • If the V-die opening size is problematic in Disabled mode, re-calculation with equal segments may be prompted.

Bumping corrections can be accessed in Automatic mode, aiding users in distributing corrections over related bends within the DELEM DA-53T Product Programming framework.

Programming parameters

In DELEM DA-53T Product Programming, parameters in program mode can be input individually, and their effects on other parameters are automatically computed.

The interplay between parameters is visually represented with symbols and background colors:

Information Symbol:

Appears when a parameter changes due to a recently edited input. This indicates the interdependency of parameters.

Star Symbol:

Displayed when a parameter value differs from the control’s calculated value. This is useful for identifying values that are intentionally set differently or constrained by parameter limits.

Error Symbol:

Shown when a parameter’s value is incorrect based on current programming. For example, this occurs when a hemming bend is programmed without appropriate hemming tools.

These symbols and their color backgrounds enhance user understanding of parameter relationships and ensure accuracy in programming within the DELEM DA-53T framework.
