Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Please refer to Figures 1-7. The present invention provides a technical solution: a punching machine for processing protective gaskets with an ejection moving mechanism. According to Figures 1, 2, 3 and 4, a punching machine frame 2 is arranged on the upper end of the punching table 1, and a hydraulic punching device 3 is arranged in the middle of the inner side of the upper end of the punching machine frame 2. At the same time, the output end of the hydraulic punching device 3 is connected to a punching block 4, and the punching block 4 is pushed downward by the hydraulic punching device 3 to facilitate the punching of the gasket raw material. A feeding mechanism 5 is arranged on one side of the upper end of the punching table 1, and the feeding mechanism 5 includes a feeding channel 501, a support frame 502, a pushing assembly 503 and a driving assembly. The rear side of the feeding channel 501 is connected to the upper end of the punching table 1 through the support frame 502, and a pushing assembly 503 is installed on the side of the feeding channel 501 away from the punching machine frame 2, and a driving assembly is arranged on the outer side of the pushing assembly 503.

Specifically, the pushing assembly 503 includes a fixed frame 5031, and the fixed frame 5031 is installed on the outside of a pushing port opened on one side of the feeding channel 501, and a pushing rack 5032 is arranged in the middle of the fixed frame 5031, the pushing rack 5032 is an I-shaped structure, and a buffer spring 5033 and a threaded ring seat 5034 are sleeved in the middle of the pushing rack 5032, one end of the buffer spring 5033 is connected to one end of the pushing rack 5032 located inside the feeding channel 501, and the other end of the buffer spring 5033 is connected to the inside of the threaded ring seat 5034, and at the same time, the outer side of the threaded ring seat 5034 is threadedly connected to the inner side of the pushing port, and the pushing rack 5032 and the threaded ring seat 5034 are movably connected.

Specifically, the driving assembly includes an installation side plate 504, and the bottom of the installation side plate 504 is connected to the upper end of the punching table 1, and a rotating motor 505 is installed on the outer side of the installation side plate 504.

When in use, the gasket raw materials are neatly stored in the feeding channel 501. When feeding is required, the rotating motor 505 is started to drive the rotating shaft 506 to rotate, so that the eccentric rotating disk 507 rotates synchronously, and then the extrusion protrusion 508 installed on the eccentric rotating disk 507 squeezes one end of the pushing rack 5032, so that the pushing rack 5032 moves into the feeding channel 501, and pushes the gasket raw materials at the bottom of the feeding channel 501, so that the inside of the feeding channel 501 The lower end falls into the limit frame 702, and then the rotating motor 505 continues to drive the rotating shaft 506 and the eccentric turntable 507 to rotate synchronously, so that the extrusion protrusion 508 installed on the eccentric turntable 507 is separated from one end of the pushing rack 5032, so that the other end of the pushing rack 5032 moves toward the outside of the feeding channel 501 under the action of the buffer spring 5033, so that the gasket raw material placed in the feeding channel 501 falls, so as to repeat the above steps to feed the raw material gasket.

When in use, the connecting piece 602 is driven to rotate by the conveying motor 601, and at the same time, the other end of the connecting piece 602 pushes the cross bar 604 horizontally through the connecting rod 603, so that the driving gear 605 moves on the lower rack 606 while driving the upper rack 607 and the moving seat 609 and the placing component 7 to move horizontally as a whole, and the gasket raw material is conveyed to the bottom of the stamping block 4. Conversely, the moving seat 609 and the placing component 7 are moved as a whole to the bottom of the feeding channel 501.

Further explanation, the moving seat 609 is arranged in a moving cavity 101 opened in the middle of the upper end of the stamping table 1, and the middle of both sides of the moving seat 609 and the middle of both sides of the moving cavity 101 are slidably connected with the linear guide rails 102 symmetrically installed, thereby improving the stability of the movement of the moving seat 609. At the same time, limiting grooves 103 are symmetrically opened in the middle of the upper and lower ends of the moving cavity 101, which is convenient for the limited movement of the placement component 7 and the meshing movement of the upper rack 607 and the driving gear 605.

Specifically, the placement component 7 includes a support platform 701, a limit frame 702, an electric telescopic member 703 and an ejection component. The support platform 701 is arranged in the middle of the upper end of the movable seat 609, and the support platform 701 is a T-shaped structure. At the same time, a limit frame 702 is installed on the upper end of the support platform 701 to facilitate the limited placement of the gasket raw material and improve the accuracy of the position during stamping. The electric telescopic member 703 is symmetrically installed at the lower end of the limit frame 702 to facilitate the limited fixation of the placement plate 704 during stamping, and an ejection component is arranged inside the limit frame 702 and the support platform 701.

To further illustrate, the ejection assembly includes a placement plate 704, and lower pressure columns 705 are symmetrically arranged on both sides of the lower end of the placement plate 704, and the bottom of the lower end of the lower pressure column 705 passes through the through hole corresponding to the upper end of the support platform 701 and is connected to the upper end of the lower pressure plate 706. At the same time, the lower pressure plate 706 is arranged in a groove opened in the middle of the lower end of the support platform 701, and the lower pressure column 705 is located above the support platform 701.

During use, after the stamping is completed, the electric telescopic part 703 is retracted, so that the squeezing force on the placing plate 704 becomes zero. Then, under the action of the rebound force of the compression spring 707 and the return spring 708, the placing plate 704 is pushed upward by the lower pressure column 705, and the gasket on the placing plate 704 is ejected, which is convenient for later unloading.
