On its upper surface, there are two symmetrical second positioning rack groups 120201 extending from the vertical center line on the left and right sides. The height of the second positioning rack groups 120201 gradually decreases from the vertical center line to the side. A second upper mold punch 120202 is provided on the upper surface of the lower half of the mold 1202. A semi-circular second machining part insertion groove 120203 is provided on the front surface of the lower half of the mold 1202. The inner diameter of the second machining part insertion groove 120203 is equal to the inner diameter of the first machining part insertion groove 120103. Threaded through holes are also provided on both sides of the upper surface of the lower half of the mold 1202.

[0042] The adjusting block 1203 is the same width as the upper half of the lower mold 1201, and its cross-section is a horizontal trapezoid.

The base 2202 has a threaded through hole in the middle. The machining part fastening assembly 220 also includes an adjustment knob 2203. A threaded rod 2204 is fixed to the front end of the adjustment knob 2203. The adjustment knob 2203 is threadedly fixed to the base 2202 by the threaded rod 2204. The front end of the threaded rod 2204 is fastened to a disc-shaped top plate 2205 by double nuts.

[0046] The upper surface of the sliding base plate 2201 is also provided with two threaded through holes. After the bolt passes through the threaded through holes and the elongated hole 2103, the machining part fastening assembly 220 is fastened to the swing table base assembly 210.

[0047] By adjusting the position of the workpiece fastening assembly 220 on the adjusting plate 2102, the function of punching tubes of different lengths can be realized. By tightening and loosening the adjusting knob 2203, the functions of clamping and picking up / dropping workpieces can be realized.

[0048] The punching die assembly 100 also includes a spring 130, which is sleeved on the guide rod 120105.

[0049] Guide rod 120105 passes through guide hole 1106 and is limited by nut at the upper end. Then, upper mold assembly 110 and lower mold assembly 120 are assembled in a sliding connection manner.

[0050] The spring spring 130 can push the upper die assembly (110) back to its original position after it has been stamped into place.

[0051] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
