In my work with various Biegemaschinen, I have learned that adjust the Biegewinkel accurately is essential for producing high-quality components. The bending angle affects not only the aesthetics but also the functionality of the final product. Over time, I have developed effective techniques for making precise adjustments, taking into account factors such as material type, thickness, and tooling setup. In this article, I will share my insights on how to adjust the bending angle, providing practical tips and methods that can help both beginners and experienced operators achieve optimal results in their bending operations.

How to Adjust the Angle of the Press Brake. Many novices don’t know how to use a bending machine when they first encounter it. They may simply understand how to turn it on and off before getting on the machine. In fact, there is a lot to know, and this equipment still has certain dangers. Therefore, you need to take protective measures yourself first.

Check everything before starting to use it to ensure that there are no problems before starting it. There are other correct usage methods that you need to know. The editor will introduce it in detail in the following article. In addition, before bending the plate, you need to make sure that the bending angle meets the standard. If it is not standard, the angle needs to be adjusted. The editor below will introduce to you how to adjust the bending angle.

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 the Bending Angle?

Before using a bending machine to bend materials, it is necessary to adjust various angles, including the bending force, the distance between the back gauge, the upper limit of the slider, the speed of the slider, and the adjustment of the gap between the upper and lower molds, etc., so that it can reach Actual job requirements. So how to adjust these parameters? The following is a detailed introduction

1. The adjustment of the angle of the bending machine is mainly to calculate the kN value of the sheet metal bending force according to the calculation formula, and calculate the indicated pressure P value according to Table 1, and then adjust the handwheel of the overflow valve so that the force generated Slightly larger than the kN value of the folded plate.

2. The adjustment of the back gauge distance of the bending machine requires positioning in the length direction when bending the sheet. The button on the front button box controls the motor adjustment. The adjustment value can be obtained from the rotation table on the button box. Read out, the conversion value of the revolution table is 0.1mm/revolution, and there is a handwheel for fine adjustment.

3. The upper limit of the slider of the bending machine needs to be adjusted by adjusting the position of the impact block T, which can make the rising slider stay at the required top dead center position, which can shorten the slider stroke distance and reduce the work cycle time. thereby increasing productivity.

4. The adjustment of the slow movement of the slider is related to the impact block I. Touch the travel switch to make the slider move slowly. The length of the slow travel time is adjusted by the adjustable potentiometer.

5. The adjustment of the gap between the upper and lower molds in the bending machine is done by the button on the button box on the lower right side of the operating workbench. Operate in the direction indicated by the sign on the bending machine. The initial adjustment gap should be greater than the plate thickness, depending on the workpiece being folded. The size of the angle to trim the gap

6. Of course, you can also use the hand wheel for fine adjustment. The adjustment value is displayed by the calculator. Each increase or decrease of one digit is 0.1mm.

How to Adjust the Stroke Length of the Press Brake?

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.

In short, the stroke adjust the bending angle 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.
