Material selection

Generally used T8 or T10, T10A, and better 42CrMo material, it requires high strength, high toughness and good wear resistance. Cold working die steel is used. Cr12MoV is a good material. The performance can be used. Satisfy, process performance is good, the price will be high. 42CrMo is a high strength alloy quenched and tempered steel, high strength, strong toughness. Can work below 500 degrees

Terms of Use

1. Turn on the power of the bending machine, turn the key switch, press the oil pump to start, and the bending machine oil pump starts to rotate. At this time, the machine has not started working.

2, the stroke adjustment, when the official start to use the bending machine mold for bending work, you need to test the car. A bend of the plate thickness must be ensured when the upper die of the press brake is lowered to the bottom. Otherwise it will cause damage to the mold and machine. The adjustment of the stroke is also equipped with electric quick adjustment and manual fine adjustment.

3, bending machine mold slot selection, generally choose the thickness of the plate 8 times the width of the notch. For a sheet with a thickness of 4 mm, a notch of about 32 is required.

4. Check the coincidence and firmness of the upper and lower molds of the bending machine; check whether the positioning devices meet the requirements of the machining. Always check the overlap of the upper and lower molds; the indication of the pressure gauge is in compliance with the regulations.

5. The sheet material must be compacted when it is bent to prevent the sheet from lifting up and hurting the operator during bending.

6. When the sheet material is pressed, the power must be cut off and stopped after running.

7. When changing the opening of the lower die of the variable bending machine, no material is allowed to come into contact with the lower die.

8. It is forbidden to use the bending machine mold to fold the ultra-thick iron plate or the quenched steel plate, the high-grade alloy steel, the square steel and the sheet material exceeding the performance of the sheet bending machine to avoid damage to the machine tool.

9. Turn off the bending machine. Place the wooden block on the lower mold below the two sides of the cylinder to lower the upper slide to the wooden block. Exit the control system program first, then cut off the power.
