The chuck bracket 3 is arranged on the lower side of the pressure cover 2 and is connected to the pressure cover 2. The punch fixing mechanism is arranged at the lower end of the adjusting shaft 1. The adjusting shaft 1 passes through the chuck bracket 3 and is threadedly connected to the pressure cover 2, and drives the punch fixing mechanism to rise and fall. An adjusting shaft fixing structure is provided between the adjusting shaft 1 and the chuck bracket 3.

[0024] Reference Figures 2~4 A thread is arranged inside the cylindrical pressure cover 2, and the adjusting shaft 1 is provided with an adjusting section and a sliding section. The adjusting section is arranged on the upper side of the sliding section, and the diameter of the adjusting section is smaller than the diameter of the sliding section. The adjusting section is threadedly connected to the pressure cover 2, and the sliding section is arranged in the chuck bracket 3, and the lower end cooperates with the punch fixing mechanism.

[0025] The chuck bracket 3 is hollow inside, and the adjusting shaft 1 passes through the chuck bracket 3. The upper end surface of the chuck bracket 3 is provided with four threaded holes. The pressure cover 2 is arranged on the upper side of the chuck bracket 3, and the pressure cover 2 is fixed to the chuck bracket 3 by four hexagon socket bolts 9. A chuck is convexly provided in the middle of the chuck bracket 3 for installation with the feeder.

[0026] After the adjusting shaft 1 rotates and the relative height with the pressure cover 2 is adjusted, the pressure cover 2 is fixed to the chuck bracket 3.

The inner diameter of the support shaft mounting hole 701 is larger than the inner diameter of the clamp seat mounting hole 401. The elastic pin 10 is arranged in the clamp seat mounting hole 401 and the support shaft mounting hole 701 to fix the support shaft 7. The lifting eye screw 6 is arranged on the upper side of the adjusting shaft 1, and a nut is installed on the lifting eye screw 6 to prevent the lifting eye screw 6 from sliding. The push rod 5 is arranged inside the adjusting shaft 1, the upper side is in contact with the lifting eye screw 6, and the lower side acts on the support shaft 7, supporting the support shaft 7 and thus supporting the punch to prevent the punch from shaking.

[0031] Working process:

[0032] When the height of the punching structure needs to be adjusted before it is installed on the feeder, rotate the adjusting shaft 1 to adjust the vertical height of the adjusting shaft 1, and then fix the pressure cover 2 and the chuck bracket 3 with the hexagon socket bolt 9 to fix the relative height between the adjusting shaft 1 and the chuck bracket 3, and then insert the shoulder screw 8 into the adjusting shaft 1 to fix the adjusting shaft 1, and then insert the push rod 5 into the adjusting shaft 1, and the support shaft 7 is fixed by the elastic pin 10 installed on the punch clamp seat 4, and then the punch clamp seat 4 is connected to the adjusting shaft 1, and the punch is fixed in the punch clamp seat 4, and the whole is fixed to the feeder through the chuck bracket 3.

[0033] When the height of the punch needs to be adjusted after being assembled to the feeder, the shoulder screw 8 is pulled out, the adjustment shaft 1 is rotated, and the shoulder screw 8 is inserted again after the height is adjusted.
