Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, and more specifically to a high-precision sheet metal stamping die which is easy to demould. Background Art

[0002] Sheet metal stamping is a metalworking process that uses stamping equipment (such as a stamping machine) and dies to apply pressure to metal sheets to deform or separate them, thereby obtaining product parts with the desired shape, size and performance. In the sheet metal stamping process, the sheet metal, the die and the equipment are the three core elements. The sheet metal stamping process has many characteristics. First, it is a fast and easy process that can efficiently complete a large number of production tasks. Secondly, sheet metal stamping is usually a cold forming process, and there is no need to allocate time for the stamped metal to cool. In addition, the stamping process can also complete multiple complex bends and punch multiple holes in one operation, which improves production efficiency.

[0003] In existing sheet metal stamping operations, the sheet metal parts need to be removed from the mold after the stamping operation. Due to the force of the stamping, there is usually a certain amount of friction between the sheet metal parts and the mold, which makes it difficult to remove them sometimes, resulting in difficulty in demolding, affecting normal production efficiency and being unfavorable for production operations.

[0025] In a specific embodiment of the utility model, the material is placed through the recessed groove on the base 1, and then the hydraulic cylinder drives the mounting frame 4 to move downward to complete the sheet metal stamping operation. After the stamping is completed, the motor 12 drives the threaded rod 10 to rotate, and the rotating threaded rod 10 drives the lifting plate 8 to move. The lifting plate 8 will move up and down under the restriction of the limiting rod 11, and the moving lifting plate 8 drives the connecting rod 7 and the lower movable plate 6 to move upward. The upward moving lower movable plate 6 will eject the sheet metal part located in the recessed groove, thereby improving the demolding effect and efficiency. During stamping, due to the shape of the recessed groove, the lower movable plate 6 will not transfer the pressure it receives to the threaded rod 10, and will not affect its production operation.

[0026] Specifically, a limiting rod 11 is fixedly connected between the inner walls of the two mounting plates 9 , and the limiting rod 11 movably penetrates the lifting plate 8 .

[0027] In this embodiment, the lifting plate 8 is restricted by the restriction rod 11 to prevent it from rotating and limit its moving path.

[0028] Specifically, the inner walls on both sides of the base 1 are detachably connected with side support blocks 13 , and the two side support blocks 13 are both matched with the lifting plates 8 .

[0029] In this embodiment, the lifting plate 8 at the bottom is supported by the side support block 13. At the same time, when the lifting plate 8 is at the bottom and the punching operation is performed, the connecting rod 7 is supported to improve its safety during use.

[0034] Specifically, a shielding plate 14 is detachably connected between outer walls of one side of the two side support blocks 13 .

[0035] In this embodiment, the demoulding assembly is shielded by the shielding plate 14, while the normal repair and maintenance thereof is not affected.

[0036] Working principle: the material is placed through the recessed groove on the base 1, and then the hydraulic cylinder drives the mounting frame 4 to move downward to complete the sheet metal stamping operation. After the stamping is completed, the motor 12 drives the threaded rod 10 to rotate, and the rotating threaded rod 10 drives the lifting plate 8 to move. The lifting plate 8 will move up and down under the restriction of the limiting rod 11, and the moving lifting plate 8 drives the connecting rod 7 and the lower movable plate 6 to move upward. The upward moving lower movable plate 6 will eject the sheet metal part located in the recessed groove, thereby improving the demolding effect and efficiency. During stamping, due to the shape of the recessed groove, the lower movable plate 6 will not transfer the pressure it receives to the threaded rod 10, and will not affect its production operation.

[0037] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.
