How does the sheet metal bending machine grasp the bending size and how to adjust the mold?

Reading Time: 4 minutes

We all know that the material that we want to bend on the sheet metal bending machine is in compliance with the standard, and we need to have a certain control over the size of the bending, so do you know how to grasp the size of the bending? The main thing is to bend. The following article will give you a detailed introduction. In addition to the bending angle, the mold is also very important. As long as there is no problem with the use of the mold, the bending angle will be no problem. Do you know how the mold should be adjusted? Mainly about the adjustment of the machine, the adjustment of the slider stroke, and the stroke Module adjustment, gap adjustment and angle adjustment, the following is a detailed introduction, let’s take a look.

How to grasp the bending size of sheet metal bending machine:
   If you want to ensure that the bending size of the sheet metal bending machine is in compliance with the standard, you need to control the bending angle. Then the following is an introduction to the grasping method of the specific bending size:
   1. Avoid using sheet metal bending machine to bend the edge alignment, avoid large angle alignment.
   2. Preliminary inspection is carried out before formal processing, and cyclic inspection is carried out during processing.
  3. In order to avoid accumulative errors, the unfolded size must be measured each time it is processed.
  4. Choose a good processing method and a good technical preparation method to simplify the processing difficulty.
  5. The bending machine selects the appropriate machine according to the accuracy requirements of the processed product.
  6. ​​Do not choose different tools, make sure that the tip of the upper die is on the same straight line before processing.
   7. For products whose edges must be bent by a bending machine, the front bending angle must be less than 90 degrees.
   8. Determine the accuracy of the measuring instrument before processing.

Installation and adjustment of the mold for sheet metal bending machine:
   When installing the sheet metal bending machine mold, be sure to check the status of the equipment, and then install and debug according to the steps. Pay attention to personal safety when debugging. The following is the detailed adjustment content:
  1. Adjustment of the machine
  When installing the sheet metal bending machine mold, you must first understand the performance of the machine, turn on the sheet metal bending machine, adjust and check patiently, and see if the machine has previously used dust and iron chips. Prevent unnecessary trouble for later use.
  2, adjustment of slider stroke
First check whether the ratio between the thickness of the metal sheet bending machine mold and the upper and lower modules is normal. The general slider needs to be controlled at the switch point of the stroke line. This must be noted, otherwise the mold will not be used normally, but some people still Such mistakes are often made.
  3, stroke module adjustment
   After adjusting the slider stroke standard, the next step is to adjust the upper limit point of the module. Generally speaking, the module is up to the highest point, and the module and switch must be set. In this way, the staying position of the module can be flowed out, and through some of the above operations, the production efficiency can be greatly increased. In this process, the module also needs to be slowed down. Because the module must be decelerated when it is down to the bottom dead center, which protects the machine and the mold.
   4. Adjustment of the gap
   Then there is the adjustment of the gap between the molds of the sheet metal bending machine. First, measure the gap between the upper module and the lower module. The reasonable gap needs to be determined according to the sheet to be folded.
   5. Angle adjustment
Adjusting the bending angle is also the most important link. The selection of the angle is definitely related to the product requirements. Generally speaking, when bending a 90° mold, the angle must be set. The middle angle must be greater than the angle on both sides. Sometimes it may be tight. You can adjust it The screws on the machine are processed. After the adjustment, if the product does not change the demand, do not modify it again. Then, when bending, use the pressure gauge to calculate the accurate pressure number and adjust the pressure. So as not to cause mold chipping.
   The above is about how to grasp the bending size of the sheet metal bending machine in the bending process, as well as the introduction of mold adjustment. You can refer to the above method to ensure that the bending size is in compliance with the standard.
