If the cutting line 11 is pressed first and then the notch 12 is punched, the cutting line 11 will be easily broken during the process of punching the notch 12, resulting in the scrapping of the material plate 1, low yield rate, and the material plate 1 needs to be punched twice to complete the processing, resulting in high production cost of the material plate 1. Therefore, a stamping and pressing tool is needed to facilitate the processing of the material plate 1. Utility Model Content
[0004] In order to overcome the deficiencies of the above-mentioned prior art, the utility model provides a punching and pressing tooling, which solves the technical problem that the material plate is easily broken at the cutting line during the punching and cutting process, resulting in the scrapping of the material plate and low yield rate.

The crimping head assembly 22 is detachably mounted on the side of the first supporting longitudinal beam 21 close to the lower die assembly 3. The movable die base 4 is provided with a punch 41 on the side close to the lower die assembly 3. The shape of the punch 41 corresponds to the shape of the notch 12. The lower die assembly 3 is provided with a blanking through hole 30 corresponding to the punch 41, and the blanking through hole 30 is used to accommodate the punch 41.
[0023] Based on the above structure, the principle of the stamping line tooling is as follows: first, the material plate 1 is placed in a preset position on the lower die assembly 3, and is located between the lower die assembly 3 and the movable die seat 4. Then, the upper die assembly 2 begins to move toward the lower die assembly 3. When the lower end of the first supporting longitudinal beam 21 is in contact with the upper end of the movable die seat 4, the upper die assembly 2 drives the movable die seat 4 to move toward the lower die assembly 3 until the lower end surface of the punch 41 contacts the material plate 1. The upper die assembly 2 continues to move toward the lower die assembly 3. When the upper die assembly 2 reaches the preset stroke, The cutting head 222 of the crimping cutter head assembly 22 contacts the sheet 1 to form a cutting line 11. The punch 41 carries the waste material (not shown) and extends into the blanking hole 30. The blanking hole 30 is used to discharge the waste material (not shown). After the stamping is completed, the upper die assembly 2 begins to reset and retract. Since the movable die seat 4 is elastically floating and arranged between the upper die assembly 2 and the lower die assembly 3, during the retraction process of the upper die assembly 2, the upper end surface of the movable die seat 4 is always in contact with the lower end surface of the first supporting longitudinal beam 21. When the movable die seat 4 is separated from the first supporting longitudinal beam 21, the movable die seat 4 is located in a preset position. The sheet 1 is rectangular in shape, with the notches 12 arranged at the four corners of the sheet 1. The sheet 1 is provided with two cutting lines 11. Correspondingly, there are two crimping cutter head assemblies 22; there are two movable die seats 4, one movable die seat 4 has two punches 41, and the lower die assembly 3 has four blanking holes 30.
[0024] In this embodiment, the wire crimping cutter head assembly 22 includes: a cutter head seat 221 and a cutter head 222. The cutter head seat 221 is detachably mounted on the side of the first supporting longitudinal beam 21 near the lower mold assembly 3, and the cutter head 222 is detachably mounted on the side of the cutter head seat 221 near the lower mold assembly 3. The wire crimping cutter head assembly 22 and the cutter head 222 are detachably mounted on the first supporting longitudinal beam 21 and the cutter head 222, respectively. This design facilitates the replacement of the entire upper mold assembly 2 or the cutter head seat 221 when the cutter head seat 221 or the cutter head 222 is damaged, thereby improving the economy of the stamping and crimping tooling. The wire crimping cutter head assembly 22 and the cutter head 222 are respectively mounted on the corresponding first supporting longitudinal beam 21 and the cutter head seat 221 by a pair of screws.
