Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a gasket stamping mechanism. Background Technology

[0002] Gaskets are sealing components used in machinery, equipment, pipelines, and anywhere fluid is present. They are materials used both internally and externally to provide a sealing effect. Gaskets are usually mass-produced by die stamping. Most gasket processing currently involves two steps: first, the un-perforated gasket is punched out from the sheet metal, and then the gasket is punched with holes. Both of these steps require the use of stamping equipment.

[0003] For example, CN220635988U discloses a gasket stamping device, including a worktable and a limiting mechanism set on the top of the worktable for fixing the sheet metal. A square groove is opened in the middle of the top outer wall of the worktable, and a lower mold is inserted into the square groove. The top outer wall of the lower mold has multiple stamping holes distributed at equal intervals. An upper mold is set on the top of the worktable, and multiple stamping heads corresponding to the stamping holes are fixedly connected to the bottom outer wall of the upper mold at equal intervals. In this invention, after adjusting the position of the sheet metal, the position of the sheet metal can be fixed by rotating the two first rotating rods until the two limiting plates are in contact with the top of the sheet metal. Then, by starting the pressing mechanism, the sheet metal can be stamped, avoiding the sheet metal from moving and causing errors during stamping. At the same time, it does not require the operator to hold it, improving safety and facilitating use. The stamped gaskets can be stored through the storage mechanism.

[0004] However, in the existing technology, the traditional stamping mechanism is complicated to operate when changing the stamping cutter head, inconvenient to disassemble and assemble, and has low production efficiency, which limits the practicality of the device to a certain extent. Utility Model Content

[0005] The purpose of this invention is to solve the problems of complex operation, inconvenient disassembly and assembly, and low production efficiency in traditional stamping mechanisms when changing stamping cutter heads.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sealing gasket stamping mechanism, including a placement plate, with supports fixedly installed at the four corners of the lower surface of the placement plate, T-shaped grooves symmetrically opened on both sides of the upper surface of the placement plate, movable plates slidably installed inside the T-shaped grooves, and portable replacement mechanisms installed on the two sets of movable plates.

[0007] The portable replacement mechanism includes a rectangular rack fixedly mounted on the outer wall of the movable plate. Mounting plates are fixedly mounted on the top of the two sets of movable plates. An upper mold is engaged with the upper surface of the mounting plate. Anti-slip grooves are symmetrically formed on the upper surface of the upper mold. A U-shaped plate is fixedly mounted at the bottom of the two sets of movable plates. Fixing frames are symmetrically mounted on both sides of the outer surface of the placement plate. A second motor is fixedly mounted on the outer wall of one of the fixing frames. A connecting rod is driven between the two sets of fixing frames. Semi-circular gears are symmetrically driven on the surface of the connecting rod, and one end of the connecting rod is driven to the output end of the second motor. The semi-circular gears mesh with the rectangular rack. Guide rods are fixedly mounted at the four corners of the lower surface of the mounting plate, and the bottom ends of the guide rods penetrate the placement plate and are fixedly connected to the upper surface of the U-shaped plate. Several return springs are elastically arranged between the lower surface of the mounting plate and the upper surface of the placement plate. A lower mold is engaged with the upper mold at a corresponding position on the upper surface of the placement plate. A limit mechanism is provided on the upper surface of the placement plate.

[0008] In a preferred embodiment, the limiting mechanism includes symmetrically arranged sliding grooves on both sides of the upper surface of the placement plate. Both sets of sliding grooves are equipped with bidirectional lead screws. A first motor is fixedly installed on one side of the outer wall of the placement plate, and the output end of the first motor is connected to one end of the two sets of sliding grooves via a synchronous belt.

[0009] In a preferred embodiment, the surfaces of the two sets of slides are symmetrically provided with horizontal plates, and the lower surfaces of the two sets of horizontal plates are slidably connected to the slides.

[0010] In a preferred embodiment, a screw is threaded at the center of the upper surface of the two sets of horizontal plates, and a limiting plate is movably provided at the bottom end of the screw, and the limiting plate is slidably connected to the inner side wall of the horizontal plate.

[0011] In a preferred embodiment, an L-shaped frame is fixedly installed on the other side of the outer wall of the placement plate, and a hydraulic cylinder is fixedly installed on the upper surface of the L-shaped frame.

[0012] In a preferred embodiment, the output end of the hydraulic cylinder is provided with an extrusion plate, and the lower surface of the extrusion plate abuts against the upper surface of the mounting plate and the upper mold.

[0013] In a preferred embodiment, the lower mold and the upper mold are installed in corresponding positions, and the two are matching components.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This utility model features a portable replacement mechanism. When replacing the upper mold, a second motor is activated to drive the rotating rod and the semi-circular gear to rotate. The semi-circular gear, through a rectangular rack, drives the movable plate to slide and rise along the T-shaped groove, causing the mounting plate and the extrusion plate to move away from each other. Then, it engages the anti-slip groove to replace the upper mold. After replacement, the semi-circular gear continues to rotate and separates from the rectangular rack. Under the return of the return spring, the mounting plate is reset, completing the disassembly and assembly. The disassembly and assembly are more flexible and convenient, improving the practicality of the device and production efficiency.

[0016] This invention uses a limiting mechanism to place the sheet metal on the upper surface of a placement plate. Then, a first motor drives a bidirectional lead screw to rotate, which in turn moves the horizontal plates on both sides of the sheet metal towards each other, clamping and fixing both sides of the sheet metal. Subsequently, a screw is turned to move the limiting plate downwards. The limiting plate moves down along the inner wall of the horizontal plate to limit the upper surface of the sheet metal, preventing misalignment during stamping and further improving the practicality and processing effect of the device.

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a sealing gasket stamping mechanism, including a placement plate 1, with supports 2 fixedly installed at the four corners of the lower surface of the placement plate 1, and T-shaped grooves symmetrically opened on both sides of the upper surface of the placement plate 1. Movable plates 16 are slidably installed inside the T-shaped grooves, and portable replacement mechanisms are installed on the two sets of movable plates 16.

[0025] The portable replacement mechanism includes a rectangular rack 17 fixedly mounted on the outer wall of the movable plate 16. A mounting plate 19 is fixedly mounted on the top of the two movable plates 16. An upper mold 20 is snapped onto the upper surface of the mounting plate 19. Anti-slip grooves 21 are symmetrically formed on the upper surface of the upper mold 20. A U-shaped plate 18 is fixedly mounted on the bottom of the two movable plates 16. Fixing frames 13 are symmetrically fixed on both sides of the outer surface of the placement plate 1. A second motor 14 is fixedly mounted on the outer wall of one fixing frame 13. A connecting rod is driven between the two fixing frames 13. Semi-circular gears 15 are symmetrically driven on the surface of the connecting rod, and one end of the connecting rod is driven to the output end of the second motor 14. The semi-circular gears 15 mesh with the rectangular rack 17. Guide rods 22 are fixedly mounted at the four corners of the lower surface of the mounting plate 19. The bottom end of rod 22 passes through the placement plate 1 and is fixedly connected to the upper surface of the return plate 18. Several return springs 23 are elastically arranged between the lower surface of the mounting plate 19 and the upper surface of the placement plate 1. The lower mold 12 is engaged at the corresponding position of the upper mold 20 on the upper surface of the placement plate 1. The upper surface of the placement plate 1 is provided with a limit mechanism. When the upper mold 20 is replaced, the second motor 14 is started to drive the rotating rod and the semi-circular gear 15 to rotate. The semi-circular gear 15 drives the movable plate 16 to slide and rise along the T-shaped slide groove through the rectangular rack 17, so that the mounting plate 19 and the extrusion plate 5 are separated from each other. Then, the upper mold 20 is replaced by engaging the anti-slip groove 21. After the replacement is completed, the semi-circular gear 15 continues to rotate and separates from the rectangular rack 17. Under the rebound of the return springs 23, the mounting plate 19 is reset to complete the disassembly and assembly, which is more flexible and convenient.

[0026] like Figure 1-4As shown, the limiting mechanism includes symmetrically arranged sliding grooves 7 on both sides of the upper surface of the placement plate 1. Both sets of sliding grooves 7 are internally equipped with bidirectional lead screws 8. A first motor 6 is fixedly installed on one side of the outer wall of the placement plate 1, and the output end of the first motor 6 is connected to one end of the two sets of sliding grooves 7 via a synchronous belt. Horizontal plates 9 are symmetrically arranged on the surfaces of the two sets of sliding grooves 7, and the lower surfaces of the two sets of horizontal plates 9 are slidably connected to the sliding grooves 7. A screw 10 is threaded at the center of the upper surface of the two sets of horizontal plates 9, and the bottom end of the screw 10 is movably positioned... A limiting plate 11 is placed and slidably connected to the inner wall of the horizontal plate 9. The plate is placed on the upper surface of the placement plate 1. Then, the first motor 6 drives the bidirectional lead screw 8 to rotate. The bidirectional lead screw 8 drives the horizontal plates 9 on both sides to move towards each other along the bidirectional lead screw 8 to clamp and fix the two sides of the plate. Then, the screw 10 is turned to drive the limiting plate 11 to move down. The limiting plate 11 moves down along the inner wall of the horizontal plate 9 to limit the upper surface of the plate, so as to avoid the plate from shifting or misaligning during stamping and to ensure the stamping effect of the sealing gasket.

[0027] like Figure 1-4 As shown, an L-shaped frame 3 is fixedly installed on the other side of the outer wall of the placement plate 1. A hydraulic cylinder 4 is fixedly installed on the upper surface of the L-shaped frame 3. An extrusion plate 5 is driven at the output end of the hydraulic cylinder 4. The lower surface of the extrusion plate 5 abuts against the upper surface of the mounting plate 19 and the upper mold 20. The lower mold 12 and the upper mold 20 are installed in corresponding positions and are matching components. The L-shaped frame 3 and the hydraulic transmission system are combined to provide a stable stamping pressure source through the hydraulic cylinder 4. The extrusion plate 5 acts on the mounting plate 19 and the upper mold 20 simultaneously to achieve synchronous pressure on both sides and effectively avoid mold displacement. The matching upper and lower molds ensure processing accuracy and improve product consistency. The overall layout is compact, the power transmission path is short, energy loss is reduced, and the stamping operation is guaranteed to be efficient and stable.

[0028] Working principle: During installation and use, the plate is first placed on the upper surface of 1. Then, 6 drives 8 to rotate, and 8 drives 9 on both sides to move towards each other along 8 to clamp and fix the sides of the plate. Then, 10 is turned to move 11 downward. 11 moves down along the inner wall of 9 to limit the upper surface of the plate and prevent the plate from shifting or misaligning during stamping. Next, the output end of 4 drives 5 to move downward. 5 drives 19 and 20 to move downward to stamp the plate. The sealing gasket generated during stamping falls below 1 via 12 for collection. At the same time, the downward movement of 19 drives 16 to slide along the T-shaped groove, and simultaneously drives... Step 18 moves down to complete the stamping operation of the sealing gasket. When it is necessary to process sealing gaskets of different sizes, steps 12 and 20 need to be replaced simultaneously. When replacing, simply remove step 12 and start step 14 at the same time. Step 14 drives the rotating rod and step 15 to rotate. Step 15 drives step 16 to slide and rise along the T-shaped slide through step 17, so that step 19 and step 5 are separated from each other. Then, step 21 is engaged to replace step 20. After the replacement is completed, step 15 continues to rotate and separates from step 17. Under the rebound of step 23, step 19 is reset and abuts against the lower surface of step 5 to complete the disassembly and assembly. The disassembly and assembly are more flexible and convenient, and more flexible, making it suitable for large-scale application and promotion.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
