How to Adjust the Bending Machine Angle – A Practical Guide

Adjusting the angle of a bending machine involves making changes to the machine settings to achieve the desired bending angle for a specific material and thickness. Here’s a general guide on how to adjust the angle of a bending machine:

How to Operate the Press Brake Correctly?

1. Strictly abide by the safety operating procedures for bending machines and wear labor protection equipment as required. Before starting, you must carefully check whether the motor, switch, circuit and grounding are normal and firm, and check whether the control parts and buttons of the equipment are in the correct position.

2. Check the overlap and solidity of the upper and lower dies. Check whether each positioning device meets the requirements for processing. When the upper sliding plate and each positioning axis are not at the origin, run the return-to-origin program.

3. After the equipment is started, run idling for 1-2 minutes, and move the skateboard to the full range 2-3 times. If you find any abnormal sound or malfunction, you should stop the machine immediately and troubleshoot the problem. You can only work after everything is normal. The work should be under unified command by one person, so that the operator and the feeding and pressing personnel can cooperate closely to ensure that the cooperating personnel are in a safe position before sending out the bending signal accurately.

4. The sheet must be compacted when bending to prevent the sheet from lifting up and injuring people during bending. When adjusting the sheet metal die, you must cut off the power supply and stop the operation. When changing the opening of the variable lower mold, no material is allowed to come into contact with the lower mold. When working, no one is allowed to stand behind the bending machine. It is strictly prohibited to fold the sheet at one end alone.

How to Adjust Angle of the Bending Machine?

Prepare the Machine:

Ensure the press brake is properly set up and all safety measures are in place. Make sure the machine is turned off before making any adjustments.

Inspect Tooling:

Check the condition of the tooling, including the punches and dies. Ensure they are in good condition and securely mounted.

Select the Correct Tooling:

Choose the appropriate tooling for the bending task. The type and size of the tooling will impact the bending angle.

Check Material Specifications:

Refer to the specifications for the material being bent. Understand the material’s tensile strength and thickness, as these factors influence the bending process.

Calculate or Set the Tonnage:

Calculate the required tonnage based on the material properties and thickness. Set the press brake tonnage accordingly to ensure proper bending without overloading the machine.

Adjust the Ram Position:

Adjust the ram position to control the bending angle. This is typically done by setting the back gauge and depth stops on the machine. Follow the machine’s manual or programming interface to make these adjustments accurately.

Perform Test Bends:

Before bending the actual workpiece, perform test bends on scrap material to fine-tune the angle adjustments. Make incremental changes as needed until the desired angle is achieved.

Check and Measure:

After adjusting the angle, check and measure the test bends using appropriate measuring tools. Ensure the final product meets the required specifications.

Fine-Tune as Necessary:

If further adjustments are needed, fine-tune the settings based on the results of the test bends. Repeat the process until the desired angle is consistently achieved.

Document Settings:

Once the correct angle is achieved, document the machine settings, including tonnage, ram position, and tooling details. This documentation serves as a reference for future similar bending tasks.

How to Adjust the Stroke Length of the Bending Machine?

How to manually adjust the stroke

1. Turn on the limit switch on the machine and determine the upper and lower limit positions to facilitate adjustment of the stroke.

2. Manually adjust the thrust button, align the gap between the lower mold and the upper mold, and narrow the pressing gap until it meets the requirements, and then adjust;

3. Determine the loading and unloading positions, and turn on the “automatic positioning” function at the starting point;

4. According to the requirements, use the manual operation button to move the bending machine to the right or left until it meets the requirements, and determines the stroke, and the work can be completed automatically.

How to automatically adjust the stroke

1. First of all, in order to ensure the accuracy of the automatic adjustment stroke, some relevant sensors need to be installed on the machine. These sensors can detect the position and movement status of the machine;

2. By setting the parameters of the machine, the stroke can be automatically adjusted. You only need to clamp the workpiece into the machine and press the automatic mode button to automatically complete the work.

3. The automatic adjustment mode requires setting the upper and lower limit positions, automatically calculating the optimal stroke length and bending angle based on the length and width of the workpiece, and then automatically completing the work.

Conclusion

In short, the stroke adjustment of the bending machine is a very important operation link, and the appropriate adjustment method needs to be selected according to the specific workpiece requirements. Manual adjustment requires certain skills and experience, while automatic adjustment requires confirmation of the machine parameters and sensor positions. Through reasonable stroke adjustment, work efficiency can be improved and operating errors reduced.
