[0016] 3. Before loading the metal cover, the present invention controls the conveying plate to move to one side of the working table, automatically squeezing the lubricating oil inside the fuel tank into the annular pipe. The lubricating oil drips onto the inner wall of the reservoir through the oil inlet pipe, thereby reducing the friction between the metal cover and the inner wall of the reservoir during the loading process and preventing the inner wall of the reservoir from being scratched by the metal cover. During the stamping of the metal cover, it is limited by the stamping hole to ensure the stability of the stamping process. After stamping is completed, the position of the stamped part is adjusted by the movable plate, and together with the adhesion of the lubricating oil, the accuracy of the position of the stamped part during blanking is improved. By reducing friction before loading the metal cover, limiting during stamping, and accurately blanking, the stamping quality of the metal cover is jointly improved, providing a good guarantee for subsequent processing.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1: As Figures 1-7 shown, a continuous stamping device for processing hollow metal cans with guided conveying proposed in this embodiment includes a processing table 1 and a conveying plate 2 slidably arranged on its top. A conveyor 10 is arranged on one side of the processing table 1. A storage 3 is arranged above the conveying plate 2. A protection component 8 is arranged above the storage 3. A position adjustment component 9 for adjusting the position of the stamping parts is arranged outside the conveyor 10; It should be supplemented and explained here that: the conveyor 10 is a functional device in the prior art that has a conveying function for stamping parts and belongs to the prior art. There is no need to elaborate too much here, as long as it has the above functions for stamping parts; the storage 3 is a container for storing and stacking metal lids, and the metal lids are circular. The distance between the circumferential side wall of the metal lid and the storage 3 is 1 - 2 millimeters, and the thickness of the metal lid is the same as the thickness of the stamping hole, which is convenient for guiding and conveying the metal lids through the conveying plate 2; As Figures 1-3 shown in FIGS. 4 and 5, the protection component 8 includes a fuel tank 81 connected to the side wall of the processing table 1. A conveying member for conveying lubricating oil is arranged inside the fuel tank 81. The output end of the conveying member is provided with a conveying pipe 87. The output end of the conveying pipe 87 is connected to an annular pipe 85. The annular pipe 85 is sleeved above the storage 3. The output end of the storage 3 is provided with a plurality of oil inlet pipes 86, and the oil inlet pipes 86 extend to the inner wall of the storage 3; Then the pressing plate 88 pushes against the baffle 810 to one side, causing the piston plate 812 to move to one side, pushing the lubricating oil inside the pump box 813 into the delivery pipe 87, squeezing it into the annular pipe 85 through the delivery pipe 87, and flowing a small amount of lubricating oil along the inner walls of the multiple oil inlet pipes 86 and fitting to the inner wall of the reservoir 3. The lubricating oil flows downward along the inner wall of the reservoir 3, reducing the friction between the metal lid and the inner wall of the reservoir 3, and preventing the metal lid from scratching the inner wall of the reservoir 3 during the blanking process; As Figures 1-3 shown in FIGS. 4 and 5, a long rack 82 is provided on the side wall of the conveying plate 2 close to the fuel tank 81. A driving gear 83 is meshed and connected to the outside of the long rack 82. A motor is also provided on the side wall of the conveying plate 2. A driving shaft 84 is fixedly provided at the output end of the motor. The driving shaft 84 is connected to the driving gear 83; Then, the driving shaft 84 is controlled by the motor to rotate. The driving shaft 84 drives the driving gear 83 to rotate. Since the driving gear 83 is meshed and connected to the long rack 82, the conveying plate 2 can be moved in two directions; it should be supplemented here that the motor is a servo motor and can drive the driving shaft 84 to rotate in two directions; As Figure 4 shown, the conveying member includes a pump box 813 fixedly connected to the inner wall of the fuel tank 81. A piston plate 812 is slidably arranged inside the pump box 813. A movable rod 89 is fixedly arranged on the side wall of the piston plate 812. One end of the movable rod 89 movably penetrates to the outside of the fuel tank 81 and is fixedly provided with a baffle 810. A pressing plate 88 is installed on the top wall of the conveying plate 2. The pressing plate 88 cooperates with the baffle 810. A first thrust spring is sleeved on the outside of the movable rod 89; During the resetting process of the baffle 810, the first thrust spring pushes the baffle 810 outward. At this time, the piston plate 812 resets, and the lubricating oil enters the inside of the pump box 813 through the oil inlet pipe 811; As Figure 4 shown, an oil inlet pipe 811 is provided at the input end of the pump box 813. The output end of the pump box 813 is connected to the delivery pipe 87. Check valves are provided on the outer walls of both the oil inlet pipe 811 and the delivery pipe 87; it should be noted here that a filling port is provided above the fuel tank 81 for replenishing the lubricating oil at any time; The stacked metal lids in the reservoir 3 are guided and conveyed for blanking through the punching holes on the conveying plate 2, and are limited during stamping through the punching holes. Also, through the movement of the conveying plate, the unloading of the stamped parts can be completed. The blanking, stamping, and unloading of the metal lids are completed in a pipeline manner, improving the stamping efficiency of the metal lids, ensuring the stability of the metal lids during stamping and the accuracy of the placement position of the stamped parts during blanking, providing a basis for subsequent processing; Embodiment 2: As Figures 1-3, as shown in FIGS. 5-7, a continuous stamping device for processing hollow metal cans with guided conveying proposed in this embodiment is an improvement based on Embodiment 1. The position adjustment assembly 9 includes a short rack 91 fixedly connected to the other side of the conveying plate 2. An installation plate 94 is connected to the side wall of the processing table 1. A connecting shaft 95 is rotatably provided at the end of the installation plate 94. A position adjustment gear 96 is fixedly connected to the bottom wall of the connecting shaft 95. A side rack 98 is meshed and connected to the outside of the position adjustment gear 96. The end of the side rack 98 is fixedly connected to a movable sleeve 97. A limiting post 99 is slidably arranged inside the movable sleeve 97. The end of the limiting post 99 is connected to the installation plate 94. A second thrust spring is arranged on the outer wall of the limiting post 99, and the second thrust spring is arranged close to the short rack 91; Then, the short rack 91 cooperates with the position adjustment gear 96 to drive the side rack 98 to move towards one side of the upper die 6, and the stamped metal lid is squeezed by another movable plate 92 to adjust its position above the conveyor 10. With a small amount of lubricating oil at the bottom of the metal cover plate, its viscosity on the conveyor 10 is increased, providing an accurate blanking position for the stamped metal cover plate and reducing errors; Movable plates 92 are arranged on both sides of the conveyor 10. One movable plate 92 close to the short rack 91 is fixedly connected to the processing table 1. The other movable plate 92 is slidably matched with the processing table 1 and its end is fixedly connected to the movable sleeve 97. A sponge block 93 is fixedly arranged on the inner wall of the other movable plate 92; It should be supplemented here that: the sponge block 93 plays a role of elastic fixation to prevent the movable plate 92 from damaging the stamped part when adjusting the position of the stamped part; As Figures 1-3 , as shown in FIGS. 5-7, a stamping hole is formed on the top wall of the conveying plate 2. A lower die 7 is arranged on the top wall of the processing table 1 below the stamping hole. An upper die 6 is arranged above the lower die 7. The top of the upper die 6 is connected to a cylinder 5. The top of the cylinder 5 is connected to the processing table 1 through a support plate 4, and the side wall of the storage 3 is fixedly connected to the support plate 4; It can be known from the combination of Embodiment 1 and Embodiment 2 of the present invention that: before the metal lid is loaded, the conveying plate 2 is controlled to move to one side of the processing table 1, so as to automatically squeeze the lubricating oil into the annular pipe 85, and the lubricating oil drips from the inner wall of the storage 3 through the oil inlet pipe 86, thereby reducing the friction between the metal lid and the inner wall of the storage 3 during the loading process and preventing the inner wall of the storage 3 from being scratched by the metal lid; During the stamping of the metal lid, it is limited through the stamping hole to ensure the stability of the stamping process. After the stamping is completed, the position of the stamped part is adjusted by the movable plate 92, and with the viscosity of the lubricating oil, the accuracy of the position of the stamped part during blanking is improved. Reducing friction before loading the metal lid, limiting during stamping, and accurate blanking together improve the stamping quality of the metal lid and provide good guarantee for subsequent processing; Working principle: When the present invention is in use, first, metal covers are stacked inside the storage 3. Then, the drive shaft 84 is controlled to rotate to one side, so that the drive gear 83 is meshed and connected with the long rack 82, and the punching hole is controlled to move directly below the storage 3, and the metal covers are fed into the punching hole; Next, the conveying plate 2 is continuously controlled to move to one side until the conveying plate 2 covers the bottom of the storage 3 again. During this process, the pressing plate 88 pushes the baffle 810 to one side, so that the piston plate 812 moves to one side, pushing the lubricating oil inside the pump box 813 into the conveying pipe 87, squeezing it into the annular pipe 85 through the conveying pipe 87, and flowing a small amount of lubricating oil into the storage 3 along the inner wall of the storage 3 through a plurality of oil inlet pipes 86. The lubricating oil flows downward along the inner wall of the storage 3, reducing the friction between the metal cover and the inner wall of the storage 3, and preventing the inner wall of the storage 3 from being scratched during the feeding process of the metal cover; Subsequently, the drive shaft 84 is controlled to rotate in the reverse direction to move the metal cover directly above the lower die 7. At this time, the cylinder 5 is controlled to extend downward, and the metal cover is punched through the upper die 6, and the metal cover is limited by the punching hole to prevent it from shaking during punching; after punching, the drive shaft 84 is continuously controlled to rotate in the reverse direction to move the metal cover above the conveyor 10. At this time, the metal cover falls onto the conveyor 10 along the punching hole; Meanwhile, the short rack 91 cooperates with the position adjustment gear 96 to drive the side rack 98 to move to one side of the upper die 6, and the punched metal cover is extruded by another movable plate 92 to adjust its position above the conveyor 10. With a small amount of lubricating oil at the bottom of the metal cover plate, its adhesion on the conveyor 10 is increased, providing an accurate feeding position for the punched metal cover plate and reducing errors; Subsequently, the drive shaft 84 is continuously controlled to rotate, aligning the punching hole with the bottom of the storage 3 again to complete the feeding of the metal cover, then moving the punching hole above the lower die 7, and moving it onto the conveyor 10 after punching, and sequentially completing the punching of the metal covers in the storage 3 according to this step.
