Description

Technical Field

[0001] The utility model belongs to the technical field of punching machines, and in particular relates to a novel punching machine for processing aluminum-plastic pull-ring covers. Background Art

[0002] The ring-pull cap is a common container sealing and opening method, mainly used in the food, beverage, cosmetics and other industries. The design of the ring-pull cap makes it very convenient to open the container. You only need to gently pull the ring and tear it with a little force to open the can lid. In the production process of the ring-pull cap, a punching machine is needed to stamp the cover of the ring-pull cap. The existing punching machine used for the ring-pull cap requires workers to manually unload and transfer the cover after completing the stamping. Manual removal of the cover is inconvenient and also has certain safety risks, and reduces work efficiency. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a new punching machine for processing aluminum-plastic pull-ring covers. After completing the punching, the device can automatically eject the punched pull-ring covers and automatically transfer the pull-ring covers to a receiving box, eliminating the manual removal process and facilitating the collection of the pull-ring covers.

[0004] To achieve the above objectives, the utility model provides the following technical solutions: a new type of punch press for processing aluminum-plastic pull ring covers, comprising a cabinet, a lower die mounting seat is installed on the top of the cabinet, a lower die is installed on the top of the lower die mounting seat, a support column is installed on the side of the cabinet, a top plate is installed on the top of the support column, a first hydraulic cylinder is installed on the top of the top plate, a piston rod of the first hydraulic cylinder is connected to a pressing plate, an upper die mounting seat is installed at the bottom of the pressing plate, an upper die is installed at the bottom of the upper die mounting seat, a second hydraulic cylinder is installed inside the cabinet, the top end of the piston rod of the second hydraulic cylinder is connected to a top block, a mounting seat is provided on the side of the support column, a first motor and a second motor are installed inside the mounting seat, an output shaft of the first motor is connected to a first screw rod, an output shaft of the second motor is connected to a second screw rod, the first screw rod is threadedly connected to a first transmission plate, a push plate is provided on one side of the first transmission plate, the second screw rod is threadedly connected to the second transmission plate, and one end of the second transmission plate is connected to a feeding channel.

[0005] The beneficial effect of the utility model is as follows: after the device completes one stamping, the first hydraulic cylinder drives the pressure plate and the upper die to reset, and then the second hydraulic cylinder drives the top block to move upward to eject the pull ring cover stamped inside the lower die upward, and then the first motor and the second motor are controlled to operate to drive the first screw rod and the second screw rod to rotate, and under the guidance and cooperation of the guide slide bar, the second transmission plate is driven to drive the unloading channel to move close to the pull ring cover, and the first transmission plate is also driven to drive the push plate to move toward the pull ring cover, and the push plate pushes the pull ring cover away from the top of the top block and moves it to the inner side of the unloading channel, and slides along the slope surface of the unloading channel into the receiving box for collection, completing one unloading, and then the first motor and the second motor drive the first screw rod and the second screw rod to drive the first transmission plate and the second transmission plate to reset, and the next stamping work can be carried out. In summary, after completing the stamping, the device can automatically eject the punched pull ring cover and automatically transfer the pull ring cover to the receiving box, eliminating the process of manual removal and facilitating the collection of the pull ring cover.

[0006] To enhance the structural stability of the pressure plate:

[0007] As a further improvement of the above technical solution: a guide column is provided between the top plate and the cabinet, and the guide column passes through the pressure plate and is slidably connected thereto.

[0008] The beneficial effect of this improvement is that the guide pillar guides the lifting and lowering of the pressing plate and enhances the structural stability of the pressing plate.

[0009] In order not to affect the stamping effect of the pull ring cover:

[0010] As a further improvement of the above technical solution: the top surface of the top block penetrates into the mold cavity of the lower mold and forms a plane with the bottom of the mold cavity of the lower mold.

[0011] The beneficial effect of this improvement is that the top surface of the top block and the bottom of the mold cavity of the lower mold form a plane, which does not affect the stamping effect of the pull ring cover.

[0012] In order to prevent the first transmission plate and the second transmission plate from rotating together with the first screw rod and the second screw rod:

[0013] As a further improvement of the above technical solution: a guide slide bar is fixedly inserted into the inner side of the mounting seat, and the guide slide bar passes through the first transmission plate and the second transmission plate and is slidably connected to the two.

[0014] The beneficial effect of this improvement is that the guide slide rod plays a guiding role when the first screw rod and the second screw rod drive the first transmission plate and the second transmission plate, thereby preventing the first transmission plate and the second transmission plate from rotating together with the first screw rod and the second screw rod.

[0015] To prevent the pull ring cover from deflecting when pushed by the push plate:

[0016] As a further improvement of the above technical solution: one side surface of the push plate is an inwardly concave arc surface.

[0017] The beneficial effect of this improvement is that one side surface of the push plate is an inwardly concave arc surface, and when the push plate contacts the pull ring cover, the pull ring cover can be kept in the middle position of the push plate, thereby avoiding deviation.

[0018] To control the operation of this device:

[0019] As a further improvement of the above technical solution: a control device is provided on the side of the cabinet.

[0020] The beneficial effect of this improvement is that the control device is used to control the operation of the device.

[0021] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
