In the process of the upper die sliding down in the guide cylinder, it can drive the stamping column fixed on the lower surface to punch into the punching hole of the lower die seat, thereby punching the aluminum plate placed between them into a bottle cap pull ring shape and dropping it into the inclined slide groove through the punching hole, so that the bottle cap pull ring can slide into the storage box through the inclined slide groove for automatic acceptance.

This continuous stamping design reduces the adjustment time after each stamping and increases the number of stamping times per unit time, thereby improving the overall production efficiency. After the conveyor belt pushes the aluminum plate, the rotating rod can drive the eccentric shaft to push the upper die down in the guide cylinder again. At this time, the push plate driven by the first bevel gear will idle 180° until the rotating rod drives the upper die to slide in the guide cylinder. The push plate can be driven to rotate 180° again and can touch one end of the push rod of the conveyor belt to push the conveyor belt.

[0023] 3. Through the design of threaded rods, sliding columns, U-shaped frames and rollers, when the aluminum plate is punched into bottle cap pull rings, the aluminum plate can be placed on the upper surfaces of the two sets of conveyor belts and cover the upper ends of the punching holes opened on the upper surface of the lower die seat at the same time. Then, the staff can twist the hand wheel to drive the threaded rod to rotate, so that the threaded rod can drive the positive and negative threads on the outer surface to drive the two sets of sliding columns installed on the outer surface threads to slide synchronously toward the center in the limit frame, so that the two sets of sliding columns can drive the rollers rotatably installed in the U-shaped frames fixed on the outer surface to touch the two sides of the aluminum plate and push it to the center of the two sets of conveyor belts, so as to ensure that the aluminum plate is in an accurate position during stamping, avoid problems such as irregular shape and substandard size of the punched bottle cap pull ring due to the position offset of the aluminum plate, help improve the quality and consistency of the product, and make the aluminum plate slide forward between the rollers in the two sets of U-shaped frames when the conveyor belt drives the aluminum plate to move forward for a distance, so that the aluminum plate can be kept centered and not skewed when being pushed forward.

[0049] Through the design of the threaded rod 304, the sliding column 301, the U-shaped frame 302 and the roller 303, when the aluminum plate is punched into the bottle cap pull ring, the aluminum plate can be placed on the upper surface of the two sets of conveyor belts 202 and cover the upper end of the punching hole 105 opened on the upper surface of the lower die base 104 at the same time, and then the staff can turn the hand wheel 305 to drive the threaded rod 304 to rotate, so that the threaded rod 304 can drive the positive thread and the negative thread on the outer surface to drive the two sets of sliding columns 301 installed on the outer surface thread to slide synchronously toward the center in the limit frame 102, so that the two sets of sliding columns 301 can drive the outer The rollers 303 rotatably installed in the U-shaped frame 302 fixed on the surface touch the two sides of the aluminum plate and push it to the center of the two sets of conveyor belts 202, thereby ensuring that the aluminum plate is in the correct position during stamping, avoiding problems such as irregular shape and substandard size of the punched bottle cap pull ring due to the position deviation of the aluminum plate, which helps to improve the quality and consistency of the product. In addition, when the aluminum plate is driven by the conveyor belt 202 to move forward for a distance, the aluminum plate can slide forward between the rollers 303 in the two sets of U-shaped frames 302, so that the aluminum plate can remain centered and not tilted during the process of being pushed forward.

[0050] The working steps of this scheme are summarized and sorted out according to the above technical scheme: when the aluminum plate is punched into a bottle cap pull ring, the aluminum plate can be placed on the upper surface of the two sets of conveyor belts 202 and cover the upper end of the punching hole 105 opened on the upper surface of the lower die seat 104 at the same time, and then the staff can twist the hand wheel 305 to drive the threaded rod 304 to rotate, so that the threaded rod 304 can drive the positive thread and the negative thread on the outer surface to drive the two sets of sliding columns 301 installed by the outer surface thread to slide synchronously toward the center in the limit frame 102, so that the two sets of sliding columns 301 can drive the rollers 303 rotatably installed in the U-shaped frame 302 fixed on the outer surface to touch the two sides of the aluminum plate and push it to the center of the two sets of conveyor belts 202 The reduction motor 401 can then be started to drive the eccentric shaft 403 in the rotating rod 402 to rotate, so that the eccentric shaft 403 can drive the connecting arm 404 rotatably installed on the outer surface to reciprocate and push the upper die 405 to slide up and down in the guide cylinder 106. During the sliding down of the upper die 405 in the guide cylinder 106, the stamping column 406 fixedly installed on the lower surface can be driven to stamp into the punching hole 105 of the lower die seat 104, so that the aluminum plate placed between them is stamped into the shape of a bottle cap pull ring and falls into the inclined slide groove 109 through the punching hole 105, so that the bottle cap pull ring can slide into the storage box 103 through the inclined slide groove 109 for automatic reception, and the upper die 405 slides down in the guide cylinder 106 to press the aluminum plate when it is lifted up after being stamped. During the process, the rotating rod 402 can drive the second bevel gear 407 at one end to mesh with the first bevel gear 204 to rotate, and then the first bevel gear 204 can drive the push plate 206 on the lower surface of the connecting rod 205 to push the push rod 203 to drive the conveyor belt 202 to transmit, and the conveyor belt 202 can drive the transmission column 201 to rotate in the U-shaped frame 101, and the transmission column 201 can drive another set of conveyor belts 202 to transmit, so that the aluminum plate placed on the upper surface of the conveyor belt 202 transmission can be pushed forward for a distance, and in the process of the aluminum plate being driven by the conveyor belt 202 to move forward for a distance, the aluminum plate can slide forward between the rollers 303 in the two sets of U-shaped frames 302, so that the aluminum plate During the process of being pushed forward, the plate can still remain centered and not tilted, so that the aluminum plate that has not passed the stamping part can be accurately covered on the upper end of the punching hole 105 again for the stamping column 406 to perform continuous stamping operations. After the conveyor belt 202 pushes the aluminum plate, the rotating rod 402 can drive the eccentric shaft 403 to push the upper mold 405 down in the guide cylinder 106 again. At this time, the push plate 206 meshed with the first bevel gear 204 will idle 180° until the rotating rod 402 drives the upper mold 405 to slide in the guide cylinder 106. The push plate 206 can be driven to rotate 180° again and can touch one end of the push rod 203 of the conveyor belt 202 to push the conveyor belt 202.

[0051] In summary: after stamping the aluminum bottle cap pull ring, the equipment can automatically push the aluminum plate forward a distance to achieve continuous stamping. This continuous stamping design reduces the adjustment time after each stamping and increases the number of stampings per unit time, thereby improving the overall production efficiency. In addition, in the process of pushing the aluminum plate, the aluminum plate can be pushed to the center without deviation, which can ensure that the aluminum plate is in an ideal position during stamping, so that during the stamping process, the various parts of the aluminum plate are evenly stressed, which is conducive to accurately stamping out bottle cap pull rings that meet the specifications.
