[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 4As shown, a general uncoiling and cutting die structure includes a base 1, a fixing frame 2 fixedly connected to the top of the base 1, a lower die base 3 fixedly connected to the top of the fixing frame 2, a lower mounting groove on the top of the lower die base 3, a lower cutter holder 4 installed inside the lower mounting groove, a lower insert 5 installed on the side of the lower cutter holder 4, two symmetrically arranged material positioning plates 6 movably installed at the front end of the lower die base 3, the material positioning plates 6 having a trapezoidal groove structure; a T-shaped sliding groove is opened on the front end face of the lower die base 3, a slider 12 is slidably connected in the sliding groove, a triangular support frame 13 is installed at the front end of the slider 12, the material positioning plates 6 are fixedly installed on the top of the support frame 13, the front end face of the slider 12 is located inside the sliding groove, and the support frame 2 is installed at the front end of the slider 12 by bolts.

[0020] By sliding the support frame 13 along the slide groove and then tightening the bolts, the distance between the two material positioning plates 6 can be adjusted, which can be used to meet the cutting requirements of materials with different roll widths.

[0021] A movable seat 7 is provided above the lower mold base 3. An upper mold base 8 is fixedly connected to the bottom of the movable seat 7. An upper mounting groove is opened on the bottom surface of the upper mold base 8. An upper knife holder 9 is installed in the upper mounting groove. An upper insert 10 is installed on the side of the upper knife holder 9. Multiple buffers 11 are installed on the bottom of the upper mold base 8 on one side of the upper insert 10. The buffers 11 are telescopic rods.

[0022] The movable seat 7 is installed via an external frame, and a drive mechanism for raising and lowering the movable seat 7 is mounted on the frame. The drive mechanism includes hydraulic cylinders, air cylinders, etc. The movable seat 7 drives the upper insert 10 to move up and down via the upper mold base 8, and when it engages with the lower insert 5, it can cut the material.

[0023] The lower mold base 3 has lower fixing posts 14 fixedly connected to the top of both ends, and the upper mold base 8 has upper fixing posts 15 fixedly connected to the bottom of both ends on one side of the lower fixing posts 14. A protrusion 16 is installed on the side of the upper fixing post 15 near the lower fixing post 14. A groove adapted to the protrusion 16 is opened on the upper side of the lower fixing post 14.
