[0016] Beneficial effects of the present invention:

[0017] 1. Use the hydraulic drive system in the existing technology to improve the stamping equipment. On the basis of the original one-way stamping of the can body, make full use of the driving force and stroke change generated by the oil return shrinkage of the stamping equipment for the can cover stamping in the other direction, avoid wasting the energy of the oil return shrinkage of the stamping equipment, and successively perform the stamping of the can body and the can cover, which greatly improves the processing efficiency, does not need to use multiple equipment for processing, and effectively reduces the processing cost;

[0018] 2. Integrate the aluminum belt transmission components used for can body and can cover stamping together, and operate through the common transmission integrated components to form a circular aluminum belt conveying mechanism. Compared with the original one-way transmission, it saves more floor space and is convenient for maintenance of the integrated drive unit;

[0019] 3. By installing gear sets with different transmission efficiencies on the No. 1 aluminum belt transmission assembly and the No. 2 aluminum belt transmission assembly, the relative transmission speed of the two aluminum belts can be adjusted to better match the different times required for can body stamping and can cover stamping;

[0020] 4. The limit assembly composed of the upper cone and the lower cone is used as the edge limit structure of the aluminum strip transmission. The rotatable feature of the upper cone can reduce the friction with the edge of the aluminum strip, reduce the heat generated in the aluminum strip, and ensure the stamping quality. At the same time, the special structure of the cone structure with a narrow middle and wide ends can also limit the upper and lower surfaces of the aluminum strip to prevent the aluminum strip from vibrating up and down during the conveying and stamping process;

[0021] 5. The upper cone and the lower cone can be adjusted up and down, which is suitable for aluminum strips of different thicknesses and has a wide range of applicability;

[0022] 6. The structure in the original comparative document that switches the hydraulic oil circuit by vertical lifting is improved to the oil circuit switching component in the cost solution, and the oil inlet channel is switched by rotating the ball shaft, and the hydraulic oil recovery channel is adjusted at the same time. This structure is completely hidden in the oil pressure tank, and is less likely to have sealing problems and oil leakage than the original structure;

[0023] 7. Improve the hydraulically driven parts into shuttle-shaped piston parts. Compared with the original flat plate structure, the resistance to movement in the hydraulic oil is smaller, the load of the hydraulic system is also lower, and the equipment loss is reduced;

[0024] 8. When the equipment is stopped, the can body punching head and the can cover punching head are controlled by the driving unit built into the shuttle piston to seal and cover the can body mold and the can cover mold to prevent dust from falling into the production workshop and to prevent dust from contaminating the lubricating grease in the mold;

[0025] 9. By setting the cleaning component on the transmission integrated component, the surface of the aluminum strip that is about to enter the working area of ​​the mold can be cleaned while the aluminum strip is being transmitted, reducing dust contamination and reducing the impact of excessive dust on the punching and stretching operations of the punch head.

During the transportation, the cleaning roller 1102 is synchronously driven to rotate through the meshing transmission of the side gear 1105 and the side gear 1103 to wipe and clean the surface of the aluminum strip transported to the can body mold 6 and the can cover mold 7.

[0058] When the No. 1 aluminum strip conveying roller 801 and the No. 2 aluminum strip conveying roller 901 convey the aluminum strip to the can body mold 6 and the can cover mold 7 respectively, the oil pump 402 pumps the hydraulic oil in the oil tank 401 into the No. 1 ball valve 405. Because at this time the channel of the No. 1 ball valve 405 is connected with the upper oil chamber 406, the hole groove on the No. 2 ball valve 416 is disconnected from the upper return oil pipe 408, and the hole groove on the No. 3 ball valve 418 is connected with the lower return oil pipe 411. The hydraulic oil then flows from the No. 1 ball valve 405 into the upper oil chamber 406, and is continuously injected into the hydraulic chamber 501 through the upper oil filling pipe 407 and the upper oil port 502. The hydraulic oil presses the shuttle piston 504 to move downward, driving the lower pressure rod 505, the lower pad 517 and the can body punching head 506 to cooperate with the can body mold 6 to press the No. 1 aluminum strip. The aluminum strip conveyed by the conveyor roller 801 is punched to punch out the can body. At the same time, the hydraulic oil under the shuttle piston 504 is squeezed back into the lower oil chamber 409 through the lower oil filling pipe 410, flows into the manifold through the lower return oil pipe 411 and finally returns to the oil tank 401. The can body after punching and stretching is firstly released from the bottom of the can body mold 6, and pushes the second card plate 1407. By using the slope and the second spring 1410, the upper edge of the can body is moved to the bottom of the second card plate 1407, and the second card plate 1407 is stuck at the upper edge of the can body.

At the same time, through the state that the upper cone wheel 415 and the lower cone wheel 417 are meshed with the active cone wheel 414, the active cone wheel 414 rotates together with the No. 1 ball valve 405, so that the No. 2 ball valve 416 and the No. 3 ball valve 418 rotate in opposite directions, so that the hole groove on the No. 2 ball valve 416 is connected with the upper return oil pipe 408, and the hole groove on the No. 3 ball valve 418 is disconnected from the lower return oil pipe 411. The oil pump 402 pumps the hydraulic oil into the No. 1 ball valve 405, and then flows into the lower oil chamber 409 from the No. 1 ball valve 405, and is continuously injected into the hydraulic chamber 501 through the lower oil injection pipe 410. The shuttle piston 504 is driven upward by the pressure of the hydraulic oil, which also drives the can body stamping The head 506 and the can cover punching head 508 move upward, and the can body is pushed off the can body punching head 506 by the second clamping plate 1407 and falls onto the conveyor 18. At the same time, the hydraulic oil above the shuttle piston 504 is squeezed back into the upper oil chamber 406 through the upper oil filling pipe 407, flows into the manifold through the upper return oil pipe 408 and finally returns to the oil tank 401. The upward can cover punching head 508 cooperates with the can cover mold 7 to punch the aluminum strip conveyed by the second aluminum strip conveying roller 901 to punch out the can cover. After being punched and stretched, the can cover first escapes from the top of the can cover mold 7 and pushes the clamping plate 1402.
