Description

Technical Field

[0001] This utility model relates to the field of sheet metal stamping technology, and in particular to a sheet metal stamping device that facilitates demolding. Background Technology

[0002] Sheet metal work is a comprehensive cold-working process for thin metal sheets (usually less than 6mm thick), including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming (such as car bodies). Its most significant characteristic is that the thickness of the same part is consistent. Products processed through sheet metal work are called sheet metal parts. The term "sheet metal part" generally varies across different industries and is often used in assembly contexts.

[0003] Sheet metal parts are stamped and formed according to actual needs during practical use. However, existing stamping equipment generally does not have a device for quick demolding of stamped parts, and manual demolding is still required, which brings certain troubles. Some devices that do have demolding of sheet metal parts need to add a drive source, which reduces the overall linkage of the device. Utility Model Content

Two symmetrically arranged telescopic cylinders 5 are threaded through the fixing plate 4. The telescopic ends of the two telescopic cylinders 5 are provided with a moving plate 10. The lower end of the moving plate 10 has an upper mold 12. The upper end of the base plate 1 has a lower mold 11 that cooperates with the upper mold 12. A groove 14 is formed between the lower mold 11 and the base plate 1. A groove 14 is provided between the groove 14 and the lower mold 11 for material handling. The lifting mechanism includes two symmetrically arranged through slots 18 between the groove 14 and the lower mold 11. Each through slot 18 has a top plate 20. The upper end of the top plate 20 is at the same level as the lower mold 11. The lower end of the top plate 20 has two symmetrically arranged connecting rods 19. The ends of the multiple connecting rods 19 are all provided with a mating plate 17. By moving the mating plate 17, the two top plates 20 are moved, thereby lifting the stamped part in the lower mold 11, achieving the effect of quick demolding of the stamped part, and bringing certain convenience to people in taking the stamped part out.

[0022] The groove 14 is provided with a drive mechanism for driving the lifting mechanism. The drive mechanism includes two symmetrically arranged rotating rods 15 that are rotatably connected through the groove 14 and the rear end of the base plate 1. The outer walls of the two rotating rods 15 are provided with protruding plates 16, and the outer walls of the two protruding plates 16 are slidably connected to the lower end of the mating plate 17.

[0023] A through groove 6 is provided on the fixed plate 4. A transmission rod 7 is rotatably connected to the rear end of the fixed plate 4 through the through groove 6.

After the stamping operation is completed, when the telescopic cylinders 5 drive the moving plate 10 upward, the toothed plate 9 on the side wall of the positioning plate at the upper end of the moving plate 10 will mesh with the gear 8, so that the gear 8 rotates and drives the transmission rod 7 to rotate. Through the transmission connection between the transmission rod 7 and the pulley 13 and the belt between the two rotating rods 15, the two rotating rods 15 rotate, so that the protruding plate 16 on the outer wall of the rotating rod 15 rotates.
