Common breakdown causes and elimination methods of ordinary punches

  The ordinary press is a stamping ordinary press. Mainly for plate. Through the mold, can be blanking, punching, forming, drawing, dressing, fine punching, shaping, riveting and extrusion parts, and so on, widely used in various fields. 

  The design principle of the punch is to convert the circular motion into the linear motion, which is driven by the flywheel and the clutch to drive the gears, crankshafts (or eccentric gears), connecting rods, etc. to achieve the linear motion of the slider. The motion from the main motor to the connecting rod is circular motion.

  1. General punch crankshaft bearing heating shaft sleeve scraping is not good, bad smoothness scraping from scratch and polishing copper tile, check the smoothness.

  2. There are copper scraps in the oil flowing out of the bearing which lack smooth oil. The smooth oil is not clean enough to check the smooth condition. Remove the bearing for cleaning.

  3. Small clearance, poor smoothness, bad contact of the guide rail burning ab initio scraping, adjusting the clearance, pay attention to smoothness

  4. When the clutch is not combined or can not be removed after the operation of the reversal of the key with tension springs lose the elastic key cooperation too tight to replace the tension springs, scraping keys of the bonding gap

  5. When the clutch is off, the slider can't stop at the upper dead position, the brake band is not pulled enough, the brake band is worn excessively, the brake wheel has oil slipping to adjust the brake spring tension, replace the brake, wash the brake band and the wheel with oil.

  6. The material is not working, the material is not met, the position is not adjusted, the orientation is met, and the hand wheel is used to test the wheel.

  7. Connecting rod screws attack or roll or impact locking device loosening rotary locking equipment

  8. Connecting rod screw ball head in slider ball pad impact ball head and ball pad cover contact is not good, cover screw loose scrape ball head, ball pad, screw cover screw tighten

  9. Press the button (on) hydraulic punch does not work power supply circuit break, hot power off, check the general punch circuit system to eliminate defects

  The connecting rod and the slider need to have the connection point of circular motion and linear motion. There are roughly two mechanisms in the design, one is spherical, the other is pin (cylindrical), through which the circular motion is converted into the linear motion of the slider. The punch press exerts pressure on the material to make it plastic deformation, and obtains the required shape and precision. Therefore, a set of dies (divided into upper and lower dies) must be matched to place the material between them. The machine exerts pressure to make it deformed. The reaction force exerted on the material during processing is absorbed by the punch machine itself.
