The characteristics of the bending machine mold
CNC bending machine molds are divided into bending machine molds and lower molds, which are used for sheet metal stamping forming and separating molds. The mold for forming has a cavity, and the mold for separating has a cutting edge.
1. Switch on the power supply of the bending machine, turn the key switch, press the oil pump to start, the oil pump of the bending machine starts to rotate, and the machine has not started to work at this time.
2, the stroke adjustment, in the formal start of the bending machine mold bending work need to test. There must be a gap of plate thickness when the bending machine dies run down to the bottom. Otherwise, it will cause damage to the mold and machine. The adjustment of the stroke is also electric quick adjustment and manual fine tuning.
3, the bending machine mold groove selection, generally choose 8 times the width of the plate thickness of the groove. If bending 4mm sheet material, choose about 32 notches.
4. Check the adhesion and robustness of the lower die on the bending machine; Check whether the positioning devices meet the requirements of processing. Check the fit degree of the upper and lower molds frequently; Whether the indication of the pressure gauge is in conformity with the regulation.
5, the plate must be compacted when bending, to prevent the plate from bending up and injuring the operator.
6. The power supply must be cut off when the plate material is pressed and the operation is 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 the bending machine mold to fold ultra-thick iron plates or quenched steel plates, advanced alloy steel, square steel and plates that exceed the performance of the bending machine to avoid damaging the machine tool.
9, close the bending machine, to place the wooden block on the lower die under the two sides of the oil cylinder, the upper slide down to the wooden block. First exit the control system program, then cut off the power supply.
CNC bending machine, the use of imitation carbon steel plate riveting structure, vibration aging to eliminate stress field, commonly used tools have high-quality bending stiffness and credibility, all the frames are legitimate behavior, responsibility has been slack, commercial risk stability, convenient and fast control.
Before working, the upper and lower blades should be set first, and the blade gap should be established according to the thickness of the carbon steel plate to be cut, generally in the thickness of 5? 7% is in the middle, and apply each gap control board to vigorously rotate the centrifugal pump pump flywheel, so that the upper and lower blades continue to exercise once, and then use the vernier caliper to check whether the gap is suitable.
CNC bending machine includes fixed bracket, table and nut. The workbench is placed on a fixed support. The workbench consists of a base and a base. The base is connected with a long straightener splint according to the door hinge. The base is composed of a seat shell, a coil and an outer cover. The coil is placed in a concave slot of the seat guard, the top of which is covered by an outer cover. When used, the coil is inserted according to the power line, and the nut causes the interaction force, and the metal plate is clamped between the nut and the base. Due to the magnetic effect of the current clamping, the nut can be made into a variety of commodity product workpiece requirements, and can be manufactured with a surface of commodity product workpiece, and the operation process is also very simple.
