Adjust these settings according to your operational needs to ensure a smooth and accurate machining process.

Materials

Material settings are crucial for ensuring that your DELEM DA-52S performs precise bending operations. Proper configuration involves inputting the correct material type, thickness, and tensile strength to enable the system to calculate the necessary bending parameters accurately.

Step 1: Accessing Material Settings

To begin, navigate to the material settings menu on your DELEM DA-52S. Here, you have the capability to edit existing materials, program new ones, or delete materials that are no longer required. A maximum of six materials can be programmed at any given time on the control panel.

Step 2: Adjusting Material Attributes

In this window, you can edit and input the material properties essential for accurate bending operations:

• Material Name: Each material should have a unique name (up to 25 characters) that starts with a letter. This allows easy identification during programming.

• Tensile Strength: Enter the tensile strength of the material. This is crucial for the DELEM DA-52S to apply the correct force during bending operations.

• E Module: The E Module of each material must also be specified to ensure precise calculation of bending parameters.

Materials are initially listed by their ID number. To modify an existing material, select the relevant line, change the property values as needed, and confirm each entry by pressing the ENTER key.

To delete a material, position the cursor on the material line and hit the ‘delete material’ function key (S6). For adding a new material, move the cursor to an empty entry space and start programming the specific values for that material.

Program Settings

The Program Settings in the DELEM DA-52S Program Constants define how the press brake behaves during programming and production, helping operators improve accuracy, consistency, and efficiency.

Machine Number (MN)

Assigning a unique machine number is essential when multiple press brakes operate in the same facility. The number is stored in each bending program and tool filename, ensuring correct machine association.

Key functions:

• Identifies each machine uniquely

• Verifies machine number when loading programs from USB

• Requires confirmation if numbers do not match

• Changing the machine number updates all tool filenames and requires a new tool backup

Angle Correction Database (CD)

This toggle enables or disables the use of a shared angle correction database. When active, corrections entered in production are stored for future use and automatically suggested for similar bends.

The controller compares these bend properties:

• Material

• Thickness

• Die opening

• lie radius

• Punch radius

• Angle

Correction suggestions or interpolations occur when:

• The active angle is within 10° of two known bends

• The corrections of those bends differ by no more than 5°

Default Program Values

To streamline the creation of new bending programs, several default parameters can be preset:

• Y-Opening Default – Initial Y-axis opening value

• Default X-Axis Code (XC) – Default step-change code (factory value: 2)

• Default X Time (XT) – Waiting time before step change

• Default Hold Time (HT) – Dwell time at the bending position

With these optimized DELEM DA-52S Program Constants, operators can maintain consistent bending quality while reducing repetitive setup efforts.

Computation Settings

Precision in complex bending operations hinges on the efficient computation settings of your DELEM DA-52S. Calibrating algorithms and keeping software updated are key.

Step 1: Calibrate Calculation Algorithms

Maximize speed and accuracy by calibrating your calculation algorithms. Focus on the Bend Allowance (BA) setting:

l 0 = Correction Off

l 1 = Correction On

This setting determines whether to apply corrections for bend-allowance in the programming phase. Corrections applied during programming are computed and stored, and can be adjusted in production mode.

Step 2: Upgrade Software Algorithms

Regularly update your software to enhance algorithm performance and precision. Pay attention to the Bottoming Force Factor (BF), used to adjust the pressure for air-bending to achieve the desired coining pressure.

Implementing these settings ensures that your DELEM DA-52S operates with exceptional efficiency and precision. For further assistance, explore our documentation or contact our support team.

Production Settings

Production settings in the DELEM DA-52S are key for efficiently managing how workpieces are crafted using a press brake machine. Proper configuration optimizes performance and quality.

Step 1: Setting Production Variables

Set accurate production variables like batch size and speed for optimal efficiency. Use the stock count mode (SC) to count products up or down during manufacturing. Downcounting stops the machine at zero after reaching a pre-set quota, while upcounting provides ongoing progress reports. Adjust pressure correction (PC) to control valve pressure, ensuring consistency.

Use clamping correction (CC) to tweak the beam’s clamping position, achieving a firm hold by offsetting the pinch point; positive values deepen, negative values raise. X-reference correction (C1) fixes discrepancies between mechanical and displayed X-axis positions for accuracy.

Step 2: Monitoring Output Quality

Regularly review production quality, making necessary adjustments. Intermediate R for X-movement (RS) prevents collisions by adjusting the R-axis while the X-axis moves within the safety zone, ensuring smooth operations.

By configuring these DELEM DA-52S program constants effectively, you can maximize machine performance and product quality.

Backgauge Dimensions

Correct backgauge configurations are vital for maintaining the accuracy and repeatability of bends.

Step 1: Measure Backgauge Dimensions

• Gauge R Offset (RO): Set the R-axis offset for scenarios where the X-axis is outside the die safety zone. This adjustment ensures lower backgauge positions at gauge position 0 for precise bends.

• Finger Height (FH): Adjust the default finger level height to correct the R-axis during lay-on situations, enhancing bending accuracy.

• Finger Length (FL): Correct the X-axis position with the first finger level length to maintain proper positioning during operations.

Step 2: Calibrate the Backgauge Mechanism

Conduct routine calibrations to ensure your backgauge maintains the programmed positions accurately, thereby enhancing the consistency of your bending operations.

By carefully configuring and calibrating these settings, you can significantly improve the reliability and performance of your DELEM DA-52S system.

Maintenance

Maintaining the DELEM DA-52S ensures longevity and optimal performance.

Step 1: Regular Inspections

• Machine Hours: Track the operational hours to plan timely maintenance.

• Strokes Count: Monitor the number of strokes executed by the pressbeam to detect potential issues early.

Step 2: Lubrication Protocols

Ensure all moving parts are regularly lubricated to reduce friction and wear, following the manufacturer’s guidelines for lubricant types and schedules.

Data Transfer

Efficient and secure data transfer is crucial for managing DELEM DA-52S Program Constants, enabling seamless updates and sharing between machines and computers.

Conclusion

In summary, configuring the DELEM DA-52S program constants involves a series of essential steps that ensure precision and efficiency in your press brake operations. By accurately defining material attributes, program settings, computation parameters, and production configurations, you can significantly enhance both the performance and accuracy of your machine. Regular maintenance and secure data handling further contribute to the system's long-term reliability and operational stability.

Proper setup and ongoing maintenance are critical to sustaining the performance of your DELEM DA-52S equipped press brake. By following these guidelines and routinely servicing your machine, you can minimize downtime and improve overall production efficiency.
