[0002] With the continuous development of the automobile industry, the types of automobile sheet metal parts used are also increasing. Automobile sheet metal parts refer to the metal shells of automobiles, which are usually made of steel plates. In addition to playing a role in protection and aesthetics, they are also the main carriers for automobiles to bear air resistance. During the processing of automobile sheet metal parts, stamping dies are required.

[0003] The utility model with the publication number of CN214263529U provides a stamping die for processing automobile sheet metal parts, including an upper template. A stamping plate is fixedly connected to the bottom of the upper template, and first bearing plates are fixedly connected to the four corners of the bottom of the upper template. A second bearing plate is connected to the bottom of the first bearing plate, and a slot hole is provided at the bottom of the second bearing plate. A lower template is fixedly connected to the bottom of the slot hole, a guide plate is fixedly connected to one side of the lower template, and a stamping slot is fixedly connected to the inside of the stamping plate. Through the stamping plate, stamping table, first bending table, second bending table and guide plate, the upper template is stamped by a stamping device, so that the upper template moves downward, thereby driving the stamping plate to press downward. By stamping the sheet metal parts on the stamping table with the stamping plate, the shape of the sheet metal parts is changed, which is convenient for the staff to use.

[0004] During use, in order to stamp different automobile sheet metal parts, different dies need to be replaced. Most dies are fixed by bolts, which are not convenient to disassemble and assemble, and the replacement efficiency is low.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above defects. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an efficient stamping die for automobile sheet metal parts that can effectively solve the above technical problems.

The lower die component includes: a lower die base fixedly installed on the stamping bracket for automotive sheet metal parts, and a slidable lower die installed on the lower die base. The upper die component includes: an upper die base fixedly installed at the output end of the driving cylinder and capable of moving up and down, and a slidable upper die installed on the upper die base. The disassembly and assembly structure includes: a bidirectional screw rotatably located in the lower die base and the upper die base, an adjusting plate threadedly connected to the bidirectional screw, a clamping block symmetrically installed on one side of the adjusting plate, a driven gear coaxially installed on one side of the bidirectional screw, a main gear meshing with the driven gear on one side, a rotating shaft coaxially installed on the main gear, a positioning shaft installed between the rotating shafts, and rotatable fastening bolts symmetrically installed on the surface of the rotating shaft.

[0008] Further, the rotating shaft is of a hollow structure, and the diameter of the rotating shaft is larger than that of the positioning shaft.

[0009] Further, sliding blocks are symmetrically installed at the bottom end of the lower die and the top end of the upper die, and sliding grooves corresponding to the sliding blocks are formed on the upper surface of the lower die base and the lower surface of the upper die base.

[0010] Further, clamping grooves corresponding to the clamping blocks are formed on both sides of the lower die and the upper die.

[0011] Compared with the prior art, the present utility model has the following beneficial effects: By screwing the fastening bolt into the screw hole on the positioning shaft, the positioning shaft can be fixed. Rotating the rotating shaft, the main gear drives the driven gear to rotate, the bidirectional screw rotates, the adjusting plate drives the clamping block to move in both directions until the clamping block disengages from the clamping grooves on both sides of the lower die and the upper die, achieving the purpose of quickly disassembling the lower die and the upper die for replacement. During stamping, unscrew the fastening bolt, and the positioning shaft moves up and down with the upper die base, which can play a guiding role for the upper die base and improve the stability of its movement.
