An ordinary punch is an ordinary punch. Mainly for plates. Blanking, punching, forming, stretching, trimming, fine punching, shaping, riveting and extruding parts can be made through the die, which is widely used in various fields. The design principle of punching machine is to convert circular motion into linear motion, and the flywheel is driven by the main motor, and the gear, crankshaft (or eccentric gear) and connecting rod are driven by the clutch to realize the linear motion of the slider. The motion from the main motor to the connecting rod is circular.

1. Generally, the crankshaft bearing heating shaft sleeve of a punching machine is not scraped well. Scrape the copper tile from scratch and check the smoothness.

2. There are copper scraps in the oil flowing from the bearing, and there is no lubricating oil. If the lubricating oil is not clean, check the smoothness and remove the bearing for cleaning.

3. The gap between the guide rails is too small, the smoothness is poor, and the contact from the beginning is poor. Adjust the gap and pay attention to the smoothness.

4. In the process of operation, the clutch is not engaged or cannot be separated after engagement. The elastic key is lost with the tension spring, and the meshing gap between the tension spring and the grinding and scraping key is replaced too tightly.

5. When the clutch is disengaged, the slider cannot stop at the top dead center. Insufficient tension of the brake band, excessive wear of the brake band, and lubricating oil on the brake wheel. Adjust the tension of the brake tension spring, replace the brake, and clean the brake band and wheel circumference with kerosene.

6. When the stripper is not working, the meeting direction is incorrect. Adjust the direction of the meeting, roll the flywheel by hand and try to back off.

7, connecting rod screw rolling or impact locking equipment loose rotating locking equipment.

8. When the ball head of the connecting rod screw hits the ball head in the ball pad of the slider, it has poor contact with the gland of the ball pad. Loosen the gland screw, scrape off the ball head and ball pad, and tighten the gland screw.

9, press the button (open) hydraulic punch power circuit does not work, thermal circuit breaker power failure, check the general punch circuit system to eliminate problems.

For circular motion and linear motion, there must be a connection point between the connecting rod and the slider. There are two kinds of mechanisms in its design, one is ball type, and the other is pin type (cylindrical type). Through these two mechanisms, the circular motion is transformed into the linear motion of the slider. The punch presses the material to plastically deform it, thus obtaining the required shape and accuracy. Therefore, it is necessary to cooperate with a set of molds (divided into an upper mold and a lower mold) to put the material between them, and the machine exerts pressure to deform it. The reaction force caused by the force applied to the material during machining is absorbed by the main body of the punching machine.
