Frequently asked question
What is the correct operation method for hydraulic bending machine?
The perfection of bent parts depends on the correct operation method of the operator. Below, the manufacturer of the shearing and bending machine will briefly introduce the operation steps and methods of the hydraulic bending machine.
1. Connect the power supply of the hydraulic bending machine, turn the key switch, press the oil pump to start, and the hydraulic oil pump of the bending machine starts to rotate. At this time, the machine has not yet started working.
2. Travel adjustment requires a trial run when starting to use hydraulic bending machine molds for sheet metal bending work. When the upper mold of the hydraulic bending machine descends to the bottom, there must be a gap of plate thickness. Otherwise, it will cause damage to the bending machine mold and machine. The adjustment of the folding bed mold stroke also includes electric quick adjustment and manual fine adjustment.
3. The selection of slots for hydraulic bending machine molds generally requires selecting slots that are 8 times the width of the plate thickness. If bending a 4mm sheet metal, a slot of about 32 should be selected.
4. Check the overlap and firmness of the upper and lower molds of the electro-hydraulic bending machine; Check whether each positioning device meets the requirements for processing. Regularly check the overlap between the upper and lower molds of the hydraulic bending machine, and whether the pressure gauge reading complies with regulations.
5. When bending metal sheets, they must be compacted to prevent the sheet metal from lifting and injuring operators during hydraulic bending.
6. When adjusting the sheet metal bending machine and pressing the mold, the power must be cut off and the operation must be stopped before proceeding.
7. When changing the opening of the variable hydraulic bending machine, no sheet metal material is allowed to come into contact with the lower mold.
8. It is prohibited to use hydraulic press bending molds to bend excessively thick iron plates or quenched steel plates, high-grade alloy steel, square steel, and plates that exceed the performance of the plate bending machine, in order to avoid damaging the hydraulic bending machine.
9. Turn off the electro-hydraulic bending machine and place wooden blocks on the lower mold below the oil cylinders on both sides to lower the upper sliding plate onto the wooden blocks. Exit the control system program first, and then cut off the power.
