[0022] A movable punching and positioning hardware module for QDC machines, see Figures 1-3 It includes an upper mold base 10 and two sets of sleeve pin modules 20;

[0023] The upper mold base 10 has a pair of recessed positioning holes 11 at one end of the central area for placing the material sheet. The two recessed positioning holes 11 are arranged on both sides of the width of the central area. The other end of the upper mold base 10 corresponding to each recessed positioning hole 11 is provided with a recessed straight groove 12. The recessed straight groove 12 extends to the other end of the lower mold base 10 in the length direction. The recessed straight groove 12 is open at the other end of the lower mold base.

[0024] Each set of sleeve pin modules 20 includes a positioning block 21 and a lower protruding sleeve pin 22;

[0025] There is a gap between the concave positioning hole 11 and the concave straight groove 12. The concave positioning hole 11 is used to fix the punch. The positioning block 21 is embedded in the concave straight groove 12. The distance L between the lower convex sleeve pin 22 on the same side and the concave positioning hole 11 is a set distance value.

[0026] In a specific embodiment, the distance between the lower convex sleeve pin 22 and the concave positioning hole 11 is more than 10 mm, and the maximum limit of the distance depends on the length of the upper mold base 10.
