The punching rod scheduling structure of a leather punching machine includes a punching machine. One side of the punching machine is sequentially arranged with a main shaft, a scheduling screw, a punching rod, a punching sleeve, and a punching rod from top to bottom axis. The upper end of the main shaft is connected with a punching rod, which is sleeved on an eccentric shaft. The eccentric shaft is driven by a motor to rotate. The lower end of the main shaft is connected with the upper end of the scheduling screw, and the lower end of the scheduling screw is screwed with the upper end of the punching rod. The punching sleeve is fixed at the lower end of the punching rod and the punching sleeve is sleeved inside the punching sleeve. The main shaft is installed on the main shaft auxiliary seat, and the punching rod is installed on the punching rod auxiliary seat. The middle of the punching rod is sleeved with a reset spring. One side of the punching machine is equipped with a scheduling screw positioning plate, and the There is a through-hole on the positioning plate, and the middle of the scheduling screw is located inside the through-hole, with the tail screw connected to the upper end of the punch rod, The outer wall of the scheduling screw on the lower side of the scheduling screw positioning plate is equipped with a limiting protrusion. During operation, the head of the scheduling screw can be disassembled and connected to the lower end of the main shaft, creating a gap between the upper surface of the limiting protrusion and the lower surface of the scheduling screw positioning plate.

results:

1. After setting up the structure of the scheduling screw positioning plate and the limiting convex edge, when the scheduling screw needs to be scheduled upwards, due to the limiting effect of the scheduling screw positioning plate and the limiting convex edge, the scheduling screw cannot move upwards, and can only push the punch rod downwards to adjust the punch and punch rod height. This ensures that the height of the scheduling screw's vertex is consistent, making it easy to hook the scheduling screw smoothly when changing the spindle, and also making the lowest point height of each punch consistent in scheduling.

2. After adjusting the processing depth of punches with different lengths on the equipment, it is convenient to use a standardized tool setter to adjust the height of each punch. Unlike traditional leather punching machines, which require trial punching to adjust the punch height when changing the punch pattern, it is laborious and time-consuming.

The

3. The lower end of the spindle is connected to the upper end of the scheduling screw, allowing the punching rod to reset in a timely manner under the drive of the tension spring and spindle during high-speed punching, thereby improving punching power.

4. There is a gap between the upper surface of the limiting convex edge and the lower surface of the scheduling screw positioning plate, so that when the punch is reset to the highest point, the limiting convex edge on the scheduling screw always does not contact the scheduling screw positioning plate, avoiding the impact noise between the scheduling screw and the scheduling screw positioning plate during the punching process.

5. The punch sleeve at the lower end of the punch rod is improved into a conical equipment contact surface according to the hole installation. A circular groove is machined in the middle of the conical surface, which is characterized by maintaining concentricity with the punch rod after replacing the punch. The circular groove is more conducive to fixing the punch sleeve.
