Description

Technical Field

[0001] This utility model relates to the field of stamping forming equipment technology, and more specifically, to a stamping forming equipment for lunch boxes. Background Technology

[0002] The stamping and forming equipment for aluminum foil lunch boxes is mainly used to process aluminum foil materials into lunch boxes that meet the specifications through stamping. Aluminum foil materials are usually provided in roll form, and the equipment needs to feed the aluminum foil rolls into the stamping mold through an automatic feeding system.

[0003] Aluminum foil lunch boxes are lightweight. Generally, an ejection mechanism is used to separate the formed lunch box from the mold, and then the lunch box is transported to the next work station for stacking via a conveyor belt. The lunch boxes are stacked neatly by hand, which increases labor costs. Existing technology installs intelligent robotic arms on the outside of the conveyor belt, but the purchase price of robotic arms is high, and the conveyor belt requires a large area, which is not economically efficient for small and medium-sized enterprises.

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a stamping and forming device for lunch boxes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping and forming device for lunch boxes, comprising a worktable, a support plate fixedly connected to the top of the worktable, a hydraulic cylinder fixedly connected to the top of the support plate, a lifting plate fixedly connected to the bottom of the hydraulic rod of the hydraulic cylinder, an upper mold installed in the middle of the bottom of the lifting plate, pressing components installed on the front and back of the bottom of the lifting plate, a flipping component installed in the middle of the bottom of the worktable, a material ejection component installed on the front and back of the bottom of the worktable, a reset component installed at the bottom of the material ejection component, the material ejection component including a guide plate fixedly connected to the bottom of the worktable, a wedge plate provided on the inner side of the guide plate, a pusher plate fixedly connected to the surface of the wedge plate near the flipping component, guide blocks fixedly connected to both sides of the wedge plate, a guide groove provided on the side of the guide plate, and the guide groove slidably connected to the guide block.

[0006] As a preferred embodiment of this utility model, the pressing assembly includes a fixed rod fixedly connected to the bottom of the lifting plate, a push plate fixedly connected to the bottom of the fixed rod, and a roller movably sleeved on the bottom of the push plate.

[0007] As a preferred embodiment of this utility model, a connecting hole is provided in the middle of the top of the workbench, and rectangular holes are provided on both the front and back sides of the top of the workbench.

[0008] As a preferred technical solution of this utility model, the flipping assembly includes a support block fixedly connected to the bottom of the workbench, a motor fixedly connected to the left side of the support block, a support rod fixedly connected to the output shaft of the motor, an mounting plate fixedly sleeved on the outside of the support rod, and a lower mold fixedly connected to the top and bottom of the mounting plate.

[0009] As a preferred technical solution of this utility model, the reset assembly includes a fixed plate fixedly connected to the bottom of the guide plate, a bottom plate fixedly connected to the bottom of the fixed plate, a reset rod movably sleeved in the middle of the top of the bottom plate, and a cylindrical hole opened in the middle of the top of the bottom plate, through which the reset rod passes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by providing a pressing component, a material ejection component, and a resetting component, allows the hydraulic cylinder to push the lifting plate downwards during the next stamping. This causes the pressing component to move downwards and pass through the rectangular hole. The rollers press the inclined surface of the wedge plate, and through the cooperation of the guide block and the guide groove, the wedge plate tilts downwards towards the flipping component. Subsequently, the pusher plate pushes the lunch box attached to the outside of the bottom mold downwards, causing the lunch box to move vertically downwards and separate from the outside of the bottom mold. It also enables automatic stacking of lunch boxes, eliminating the need for manual or robotic stacking of the formed lunch boxes. The equipment has a small footprint and high reliability.

[0014] 2. This utility model is equipped with a pressing component and a material ejection component. When the upper mold moves vertically downward to press and form the material, the pressing component moves vertically downward simultaneously. The rollers squeeze the inclined surface of the wedge plate. Since rolling friction occurs when the rollers contact the surface of the wedge plate, the friction force is small, which can reduce the wear of the contact surface. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6As shown, this utility model provides a stamping and forming device for lunch boxes, including a workbench 1, a support plate 101 fixedly connected to the top of the workbench 1, a hydraulic cylinder 102 fixedly connected to the top of the support plate 101, a lifting plate 103 fixedly connected to the bottom of the hydraulic rod of the hydraulic cylinder 102, an upper mold 104 installed in the middle of the bottom of the lifting plate 103, pressing components 2 installed on both the front and back of the bottom of the lifting plate 103, a flipping component 3 installed in the middle of the bottom of the workbench 1, and the bottom of the workbench 1... The front and bottom back of the workbench 1 are equipped with ejector components 4. The bottom of the ejector components 4 is equipped with a reset component 5. The ejector components 4 include a guide plate 401 fixedly connected to the bottom of the workbench 1. A wedge plate 402 is provided on the inner side of the guide plate 401. A pusher plate 403 is fixedly connected to the surface of the wedge plate 402 near the flipping component 3. Guide blocks 404 are fixedly connected to both sides of the wedge plate 402. A guide groove 411 is provided on the side of the guide plate 401. The guide groove 411 is slidably connected to the guide block 404.

[0024] In this embodiment, after the lunch box is stamped, the motor 302 drives the mounting plate 304 to rotate 180° via the support rod 303, thereby driving the top lower mold 305 to rotate downwards. The formed lunch box may be attached to the outside of the lower mold 305. During the next stamping, the hydraulic cylinder 102 pushes the lifting plate 103 downwards, thereby moving the pressing component 2 downwards and passing through the rectangular hole 12. The roller 203 squeezes the inclined surface of the wedge plate 402. Through the cooperation of the guide block 404 and the guide groove 411, the wedge plate 402 tilts and moves downwards towards the flipping component 3. Then, the pusher plate 403 can push the lunch box attached to the outside of the bottom lower mold 305 downwards, so that the lunch box moves vertically downwards and separates from the outside of the lower mold 305. It can also realize the automatic stacking of lunch boxes without the need for manual or robotic arms to stack the formed lunch boxes. The equipment has a small footprint and high reliability.

[0025] The pressing component 2 includes a fixed rod 201 fixedly connected to the bottom of the lifting plate 103, a push plate 202 fixedly connected to the bottom of the fixed rod 201, and a roller 203 movably sleeved on the bottom of the push plate 202.

[0026] During the process of the upper mold 104 moving vertically downward to stamp and form the material, the pressing component 2 moves vertically downward simultaneously, and the roller 203 squeezes the inclined surface of the wedge plate 402. Since the roller 203 and the surface of the wedge plate 402 come into contact with rolling friction, the friction force is small, which can reduce the wear of the contact surface.

[0027] The workbench 1 has a connecting hole 11 in the middle of its top, and rectangular holes 12 are provided on both the front and back sides of its top.

[0028] The hydraulic cylinder 102 pushes the lifting plate 103 downward. The upper mold 104 passes through the connecting hole 11 and the lower mold 305 at the top to extrude and form the raw material. The rectangular hole 12 is adapted to the push plate 202.

[0029] The flipping component 3 includes a support block 301 fixedly connected to the bottom of the workbench 1. A motor 302 is fixedly connected to the left side of the support block 301. A support rod 303 is fixedly connected to the output shaft of the motor 302. An installation plate 304 is fixedly sleeved on the outside of the support rod 303. A lower mold 305 is fixedly connected to the top and bottom of the installation plate 304.

[0030] The motor 302 is connected to an external PLC control system. After a lunch box is formed, the motor 302 drives the support rod 303 to rotate 180°, causing the upper mold 305 attached to the top to rotate downwards.

[0031] The reset assembly 5 includes a fixed plate 501 fixedly connected to the bottom of the guide plate 401, a bottom plate 502 fixedly connected to the bottom of the fixed plate 501, a reset rod 503 movably sleeved at the middle of the top of the bottom plate 502, a connecting plate 421 fixedly connected to the bottom of the wedge plate 402, a connecting rod 422 fixedly connected to the inner side of the connecting plate 421, the connecting rod 422 movably sleeved with the top of the reset rod 503, and a reset spring 504 movably sleeved on the outer side of the reset rod 503, the reset spring 504 being located between the top of the bottom plate 502 and the bottom of the wedge plate 402.

[0032] After the lunch box is formed, the lifting plate 103 drives the upper mold 104 to move upward, so that the roller 203 no longer exerts a pushing force on the inclined surface of the wedge plate 402. The return spring 504 releases its elastic force and pushes the wedge plate 402 to tilt upward for reset, thereby avoiding the pusher plate 403 from blocking the flipping of the mounting plate 304 and the lower mold 305. A cylindrical hole 521 is opened in the middle of the top of the bottom plate 502. The reset rod 503 passes through the cylindrical hole 521. When the wedge plate 402 moves, it is in an inclined direction, so the reset rod 503 will tilt. The inner diameter of the cylindrical hole 521 is larger than the diameter of the reset rod 503 to make way for the reset rod 503.

[0033] Working principle and usage process of this utility model:

[0034] After the lunch box is stamped, the motor 302 drives the mounting plate 304 to rotate 180° via the support rod 303, thereby driving the top lower mold 305 to rotate downwards. The formed lunch box may be attached to the outside of the lower mold 305. During the next stamping, the hydraulic cylinder 102 pushes the lifting plate 103 downwards, thereby moving the pressing component 2 downwards and passing through the rectangular hole 12. The roller 203 squeezes the inclined surface of the wedge plate 402. Through the cooperation of the guide block 404 and the guide groove 411, the wedge plate 402 tilts and moves downwards towards the flipping component 3. Then, the pusher plate 403 can push the lunch box attached to the outside of the bottom lower mold 305 downwards, so that the lunch box moves vertically downwards and separates from the outside of the lower mold 305. It can realize the automatic stacking of lunch boxes without the need for manual or robotic arms to stack the formed lunch boxes. The equipment has a small footprint and high reliability.
