How to grasp the size of bending for press brake?

The main purpose of using a press brake is to grasp the size of the bending.

Avoid using a press brake to bend the edge or large-angle alignment.

Preliminary inspection is carried out before formal processing. Cyclic inspection is carried out during the use of press brake.

In order to avoid accumulative errors, the unfolded size must be measured every time when material is added.

Choose a good processing method and a good technical preparation method to simplify the processing of press brake.

The press brake selects the appropriate machine according to the accuracy requirements of the processed products.

Do not choose tools that have decentraction. Make sure that the tip of the upper die of press brake is on the same straight line before processing.

For products whose edges must be bent by a press brake, the front bending angle must be less than 90 degrees.

Determine the accuracy of the measuring instrument before processing.

How should you use press brake?

Strictly abide by the safe operation regulations of press brake. The user must wear labor protection. Before starting, carefully check the motor, switch, circuit, grounding, and the control parts and buttons of the press brake.

Run press brake idling for 1 to 2 minutes and move on the slide 2 to 3 times at full stroke. If there is anything abnormal, stop immediately to troubleshoot the malfunction.

The sheet material must be compacted when bending to prevent hurting people during bending. The power supply must be cut off when adjusting the sheet metal die. When changing the opening of the lower mold, no material is allowed to come into contact with the lower mold. When press brake works, no one is allowed to stand behind the press brake.

It is forbidden to use press brake molds to fold over-thick iron plates or hardened steel plates.

To close the press brake, place a wooden block on the lower die under the cylinders on both sides and lower the upper slide plate onto the wooden block.

How to adjust the bending angle of press brake?

Before using the press brake to bend the material, you need to adjust its various angles, including the bending force, the distance of the back gauge, the upper limit of the slider, the speed of the slider, and the adjustment of the upper and lower mold gaps.

The adjustment of the angle of the press brake is mainly to calculate the value of the bending force and indicated pressure according to the calculation formula. Then, adjust the handwheel of the overflow valve to generate the force which is slightly larger than the force of the folded plate.

The adjustment of the backgauge distance of the press brake needs to position in the length direction when bending the sheet. The button on the front button box controls the motor adjustment, whose value can be from the revolution table on the button box. There is a handwheel for fine adjustment.

The adjustment of the upper limit of the slider of the press brake needs to be realized by adjusting the position of the striker. The rising slider can stay at the required center position, which can shorten the stroke distance of the slider. It reduces the working cycle time and increases productivity.

The adjustment of the gap between the upper and lower molds in the press brake is completed by the button on the button box. Operate in the direction indicated by the press brake label. The initial adjustment gap should be greater than the thickness of the plate.

6. Oblique three-dimensional deflection compensation mechanism of press brake ensures the reduction of bending accuracy.

What should you know about the supporting wheel frame of press brake?

The press brake needs to change molds according to different products. The supporting wheel frame of press brake needs to adjust the height of the supporting material. There are problems of troublesome operation and low efficiency in the processing. By optimizing the design of the supporting wheel frame of the press brake, the goal of adjusting the height and length by rotating the lead screw is realized. It is an indispensable part of the press brake, which mainly plays the role of feeding and pushing materials.

The support roller frame is composed of 45 round steel rollers, which are set on the top and are higher than the support beams on both sides. The sheet material pushing is light and fast.

The bracket mainly plays the role of supporting the placement of the plates. It is considered to be able to place more than 10 plates at the same time and have sufficient strength. The rectangular tube frame structure can reduce the deformation of long-term high-load operations.

Traveling wheel is connected with the ground guide rails by rollers. The guide rails are set to ensure that the support roller frame walks along a straight line that is parallel to the press brake.

The frame of shearing machine is welded by the whole machine. After high-temperature quenching treatment, it has high rigidity and high strength.

What is the parameter of shearing machine?

The major parameters in shearing machine are the shape of the punch and die, the speed of punching, lubrication, and the clearance between the punch and the die.

The clearance between the punch and the die is a major factor in determining the shape and the quality of the shearing machine. As the clearance increases, the zone of deformation becomes larger and the sheared edge becomes rougher. The sheet tends to be pulled into the clearance region. The edges of the sheared zone become rougher. Secondary operations may be required to make smoother, which will increase the production cost.

Edge quality can be improved with the increasing speed of punching of shearing machine. Sheared edges can undergo severe cold working due to the high shear strains. The hardness of the edges will reduce the ductility of the edges and adversely affect the formability of the sheet during bending and stretching.
