Use of hydraulic hole opener

Core Tip: Before opening the hole in the hydraulic hole opener, first hit a 11.5mm approach hole through the hand. Then, the piston rod is screwed into the screw hole of the piston cylinder, and then the gasket is inserted into the piston rod and then inserted into the die.

Let me introduce the use of the hydraulic hole opener:

1. Before opening the hole, first punch a 11.5mm approach hole through the hand.

2. Screw the piston rod into the screw hole of the piston cylinder, then insert the washer into the piston rod and insert it into the die. Then, the piston rod is inserted into the approach hole of the workpiece, and finally the punch is screwed into, so that the edge of the punch is closely combined with the machined surface, and the punch, the workpiece and the die are reliably fixed.

3. Close the oil cutting according to the direction of the needle, and then press the 揿 force handle repeatedly to make the piston pump start working. The oil pressure is long, the shearing force between the concave and convex molds increases, and the mold cuts the hole on the workpiece until the cutting Until now.

4. Loosen the oil cutting counterclockwise to completely unload the oil pressure. The hole opening operation is completed after the above 4-step operation procedure.

5. Unscrew the punch, remove the hair plate in the die, and open the net mold.
