[0002] The metal bottom cover stamping machine is a mechanical equipment specially used to manufacture the bottom covers or top covers of various metal containers (such as food and beverage cans, milk powder cans, aerosol cans, etc.). The die applies pressure to the metal sheet to cause it to undergo plastic deformation, thereby processing the metal sheet into the required shape and specifications, obtaining the required bottom cover shape, and ensuring the sealing, durability and aesthetics of the cover. The metal bottom cover stamping machine is an indispensable part of the packaging industry. Its efficient and precise production capacity plays an important role in improving product quality and reducing costs.

[0003] When the metal bottom cover is stamped, the metal sheet needs to be compressed to undergo plastic deformation and then stretch to form the desired shape.

[0014] The present invention provides a metal bottom cover stamping machine that prevents jamming. It has the following beneficial effects: 1. The anti-jamming metal bottom cover stamping and forming machine supports and limits the sheet material of the metal bottom cover through a scraper, and uses the cooperation of the punch and the anti-jamming punch to perform a stamping operation on the sheet material. The anti-jamming punch and the scraper are used to pre-position the sheet material and complete the stamping and forming operation in steps, so that the metal bottom cover can be quickly formed, and the formed metal bottom cover can be naturally demolded, reducing the risk of jamming. The discharger is then used to assist in the discharge of the metal bottom cover, thereby further improving the utilization efficiency of the stamping and forming machine.

[0015] 2. The anti-jamming metal bottom cover stamping forming machine provides driving force through a hydraulic device to make the lifting plate drive the anti-jamming punch to descend, and uses the front contact between the external positioning part and the metal plate to pre-fix the metal plate, and then uses the corresponding settings of the scraper and the anti-jamming punch to carry out the forming process of the metal bottom cover, and cooperates with the distance adjusting part to improve the adaptive adjustment ability of the external positioning part, adjust the pressing depth, and avoid material jamming caused by overpressure. The contact between the punching part and the metal material and the through groove work together to form the metal bottom cover, thereby effectively controlling the material flow direction during the forming process to ensure the consistency and integrity of the metal bottom cover.

[0016] 3. The anti-jamming metal bottom cover stamping forming machine pre-positions the metal material through the contact between the soft rubber plate and the surface of the metal material, and cooperates with the positioning pad to reduce jams caused by misalignment. The soft rubber plate is used as a buffer layer, which not only protects the material surface, but also absorbs part of the pressure impact during the stamping process, reduces the obstruction to the material flow, and ensures the stability of the metal bottom cover forming process. The positioning pad is then subjected to contact pressure and slides on the outside of the outer pressure barrel, thereby squeezing the pressure rod to slide in the sleeve, compressing the spring to deform, and generating a rebound force. The elastic force acts to ensure that after the stamping is completed, the forming head can be assisted in the separation of the stamping waste, avoiding the problem of carrying away the waste due to the scraping friction after stamping, which affects the subsequent processing process.

[0017] 4. The anti-jamming metal bottom cover stamping forming machine effectively solves the pressure imbalance problem caused by gas accumulation during the stamping process by opening the exhaust groove and combining it with the compression spring. The arrangement of the exhaust groove ensures the rapid discharge of gas and reduces the obstruction to the flow of materials, thereby reducing the probability of jamming. The compression spring is used to provide the forming head with rebound force after being compressed. By adjusting the gap between the forming head and the external pressure barrel, while maintaining the full extension of the material, excessive pressure accumulation is avoided, and the smooth flow of the material is promoted, thereby ensuring the forming path of the material and further reducing the risk of jamming.

[0018] 5. The anti-jamming metal bottom cover stamping and forming machine is convenient for limiting the position of the metal plate through the arrangement of the plate groove, and cooperates with the movable scraper ring plate to be affected by the pressure during the downward pressing process of the forming head, and slides on the inner wall of the fixed ring plate to compress the elastic sheet to deform and generate elastic force, and uses the limiting ring rod and the baffle plate to limit the elastic sheet, thereby limiting the deformation amount of the elastic sheet and the sliding position of the movable scraper ring plate, and uses the forming head to penetrate through the movable scraper ring plate to push the formed metal bottom cover out, and uses the reset operation of the movable scraper ring plate caused by the action of the spring sheet after the stamping is completed to scrape the surface of the forming head, and assist in scraping off the metal bottom cover that may be retained on the surface of the forming head and enter the space of the discharge chute, so that the cylinder and the push plate cooperate, and use the push arc block to quickly push out the metal bottom cover, thereby ensuring the safety and efficiency of the overall stamping process.
