[0016] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0017] In the present invention, the first motor 6, the second motor 17, the first cylinder 7 and the second cylinder 16 are all connected to the external electric control system through wires. The above devices and connection methods are all existing technologies and will not be described in detail here.

[0018] According to the instruction manual Figure 1It can be known that when the utility model is in use, firstly, the corresponding mold assembly is selected according to the requirements of stamping and shaping, and the second cylinder 16 is moved to the top of the corresponding mold assembly by the moving assembly. The upper mold 12 and the lower mold 4 in each group of mold assemblies have different shapes, which can be processed into a preset shape according to production needs. The shape of the lifting part 8 matches the shape of the stamping groove of the lower mold 4. Secondly, the metal sheet is set between the upper mold 12 and the lower mold 4, and the second cylinder 16 is started. The telescopic end of the second cylinder 16 extends downward, and when it abuts against the upper mold 12, it drives the upper mold 12 to move vertically downward. The upper mold 12 drives the connected pair of limit plates 11 to move vertically downward. Multiple pairs of vertical rods 9 penetrate a pair of limit plates 11 to limit the limit plates 11 to prevent the limit plates 11 from deflecting when moving. When the pair of limit plates 11 moves, the multiple compression springs 10 set between the limit plates 11 and the second vertical plate 3 are contracted, and the metal sheet is stamped and shaped by the cooperation between the upper mold 12 and the lower mold 4. After the stamping is completed, the telescopic end of the second cylinder 16 contracts, and the limit plate 11 moves upward and resets under the elastic force of multiple compression springs 10. The limit block 9-1 set on the top of the vertical rod 9 can limit the limit plate 11. Again, the first motor 6 set on the second vertical plate 3 is started, and the output end of the first motor 6 passes through the second vertical plate 3 and is connected to one of the rotating rods 5, so that the first motor 6 drives the rotating rod 5 and the lower mold 4 to rotate, and then the stamping groove of the lower mold 4 is tilted downward by a certain angle. Finally, the first cylinder 7 set on the lower mold 4 is started, and the telescopic end of the first cylinder 7 extends out to drive the connected lifting member 8 to move, and the lifting member 8 pushes the stamped material plate outward to complete the stamping operation; the utility model adjusts the position of the second cylinder 16 through a pair of moving components between the first vertical plates 2, so that the second cylinder 16 can cooperate with the mold component that meets the stamping requirements during stamping, and there is no need for personnel to change the mold many times, which saves time and effort for personnel. After stamping, the first cylinder 7 can push the material plate out for easy demoulding.

[0019] There is a possible implementation method, in which the second motor 17 is started, and the output end of the second motor 17 drives the connected threaded rod 14 to rotate. Since the threaded rod 14 is threadedly connected to the threaded sleeve 15, the threaded sleeve 15 is slidably set in the limit groove 13-1 opened in the horizontal plate 13, and the limit groove 13-1 limits the threaded sleeve 15. Therefore, when the threaded rod 14 rotates, the threaded sleeve 15 can slide in the limit groove 13-1, and the threaded sleeve 15 drives the second cylinder 16 set at the bottom to move, thereby adjusting the position of the second cylinder 16.

[0020] There is a possible implementation in which a plurality of guide plates 18 are obliquely provided at the bottom of the workbench 1 and corresponding to the positions of the plurality of discharge ports. When the first cylinder 7 pushes out the discharge plate after the stamping is completed, the guide plates 18 guide the discharged discharge plate.

[0021] In one possible implementation, a material collecting box 19 is provided at the bottom of the material guide plate 18 , and the material collecting box 19 collects the material sliding out of the material guide plate 18 .

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
