When the punching seat 5 moves up, the one-way transmission member 14 drives the rotating shaft 13 to rotate, and the bottom plate of the capacitor shell is punched by setting an automatic punching and feeding device for the capacitor shell composed of a conveyor bracket 1, a feeding roller shaft 2, a punching platform 3, a hydraulic mechanism 4, a punching seat 5 and a punching head 6, and an L-shaped bracket 11, a transmission rack 12, a rotating shaft 13, a one-way transmission member 14, a transmission gear 15 and a driven gear 16 are set, so that the feeding roller shaft 2 is synchronously driven by the movement of the hydraulic mechanism 4 to transport the plate 7 to be punched, thereby effectively optimizing the driving structure of the device to facilitate the staff to carry out daily circuit maintenance.

[0020] Embodiment 2: On the basis of embodiment 1, the one-way transmission member 14 includes a first ball bearing 18, a second ball bearing 19, a rotating tube 20, a block 22 and an elastic sheet 23. The rotating tube 20 is rotatably mounted on the rotating shaft 13 through the first ball bearing 18 and the second ball bearing 19, and the inner and outer side walls of the rotating tube 20 are respectively integrally formed with a latch tooth 25 and a gear tooth 24.

[0022] A material drop groove 32 is provided on the side wall of the lower end of the stamping groove 17. The diameter of the material drop groove 32 is larger than the diameter of the stamping groove 17. After the hydraulic mechanism 4 has completed the movement, the end of the punching head 6 enters into the material drop groove 32. A material storage box is provided on the ground directly below the stamping platform 3. The setting of the material drop groove 32 can facilitate the falling of the material formed after stamping.

[0023] The punching heads 6 are arranged in two rows, and the punching heads 6 in adjacent rows are arranged in a staggered state. The two rows of staggered punching heads 6 can effectively improve the utilization rate of the plate 7.

[0024] When the lower end surface of the punch head 6 moves to be flush with the upper surface of the punching platform 3, the transmission rack 12 and the gear teeth 24 are in a separated state, and when the hydraulic mechanism 4 is in the return state, the transmission rack 12 and the gear teeth 24 are in a separated state, thereby preventing the punch head 6 and the plate 7 from being separated and driving the feed roller 2 to move, thereby avoiding damage to the plate 7.

[0025] There are multiple models of transmission racks 12, and in actual use, the distance that the selected transmission rack 12 drives the feed roller 2 to move when it reciprocates up and down once is twice the straight-line distance between the center points of adjacent rows of punch heads 6. Transmission racks 12 of multiple lengths can be replaced and used to improve the versatility of the device.

[0026] A connecting gear 31 is rotatably installed on the conveyor bracket 1 through the installation shaft 30, and a synchronous gear 29 is fixedly installed on the rotating shaft 10 away from the driven gear 16. The models of the synchronous gear 29 and the connecting gear 31 are the same, and adjacent synchronous gears 29 are meshed with the same connecting gear 31, so that all feeding rollers 2 can run synchronously to ensure the transmission stability of the plate 7.

[0027] Embodiment 3: On the basis of embodiment 2, an adsorption groove 33 and an air channel 35 are provided on the stamping platform 3. The adsorption groove 33 is staggered with the stamping groove 17 and the blanking groove 32, and the adsorption groove 33 is connected with the air channel 35 through the connecting groove 34. The port of the air channel 35 is provided with an air pipe connector 36, and the air pipe connector 36 is connected to the air inlet port of the exhaust device through the air pipe. When the stamping head 6 is pressed down, the exhaust device starts to run, and before the stamping head 6 contacts the plate 7, the adsorption groove 33 After the sheet 7 is adsorbed and positioned, and when the punch head 6 retreats, when the lower surface of the punch head 6 is higher than the sheet 7, the pressure relief valve on the air pipe relieves the pressure in the adsorption groove 33, and the pressure relief is completed before the transmission rack 12 contacts the gear teeth 24, so that the sheet 7 can be adsorbed and positioned through the adsorption groove 33, thereby avoiding the punch head 6 from lifting the sheet 7 during the return movement, thereby causing deformation of the sheet 7, and avoiding the sheet 7 from separating from the feed roller 2 and affecting the transmission effect of the feed roller 2 on the sheet 7.

[0028] Working principle: when the hydraulic mechanism 4 is pressed down, due to the one-way limit of the block 22 and the tooth 25, the transmission rack 12 does not drive the rotating shaft 13 to move. When the punch head 6 completes the punching of the plate 7 and moves back, the transmission rack 12 drives the rotating shaft 13 to move, thereby driving the feeding roller 2, thereby conveying the plate 7 forward a certain distance, so as to realize automatic loading for the next punching step.

[0029] Although the above describes the illustrative specific implementation methods of the present application so that technicians in this technical field can understand the present application, the present application is not limited to the scope of the specific implementation methods. For ordinary technicians in this technical field, as long as various changes are within the spirit and scope of the present application defined and determined by the attached claims, all application creations using the concept of the present application are protected.
