Hydraulic bending machine mold use

The correct use of the mold of the hydraulic bending machine can ensure the safety at work, improve the production efficiency, and extend the service life of the mold.

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 to work.

2. The stroke adjustment requires a test run when the bending machine mold is officially started. When the upper die of the bending machine descends to the bottom, there must be a gap of plate thickness. Otherwise it will cause damage to the mold and the machine. The stroke adjustment also has electric quick adjustment and manual fine adjustment.

3. To choose the notch of the die of the bending machine, a notch of 8 times the width of the plate thickness is generally selected. If you bend a 4mm sheet, you need to choose a slot of about 32.

4. Check the overlap and firmness of the upper and lower molds of the bending machine; check whether each positioning device meets the requirements of being processed. Frequently check the overlap of the upper and lower molds; whether the instructions of the pressure gauge meet the regulations.

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

6. The power supply must be cut off when adjusting the sheet metal die, and the operation should be stopped.

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

8. It is forbidden to use bending machine molds to fold over-thick iron plates or quenched steel plates, high-grade alloy steels, square steels, and sheets that exceed the performance of the sheet metal bending machine to avoid damage to the machine tool.

9. Turn off the bending machine, and place wooden blocks on the lower molds under the cylinders on both sides to lower the upper slide plate onto the wooden blocks. Exit the control system program first, then cut off the power supply.
