Description

Technical Field

[0001] The utility model relates to the technical field of closing machines, and specifically relates to a closing machine with precise positioning. Background Technique

[0002] A closing machine is a device used for processing metal plates. It is mainly used for processing the edges and corners of metal plates to facilitate subsequent processes such as welding and assembly. The principle of the closing machine is to plastically deform the metal plate through a certain mechanical structure and pressure to achieve the closing process.

[0003] When performing the closing process, first place the metal plate on the processing head part, and then apply a certain pressure through the hydraulic system to make the processing head part extrude the metal plate. During the extrusion process, the metal plate will undergo plastic deformation to form the shape of the closed mouth. To ensure the stability of the metal plate during the processing, a positioning tooling is generally used to fix it. However, when pressing it tightly with mechanical pressure, the metal plate is easily deformed under pressure, which is likely to cause damage to the metal plate. Content of the Utility Model

[0004] The purpose of the utility model is to provide a closing machine with precise positioning to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A closing machine with precise positioning, including a bottom plate. The top of the bottom plate is fixedly connected with a control panel. The top of the bottom plate is fixedly connected with a support frame. The top of the support frame is fixedly connected with a connecting frame. The side of the connecting frame away from the control panel is fixedly connected with a pressing component. The pressing component includes a mounting plate. The top of the mounting plate is fixedly connected with an electric lifting rod. The bottom of the electric lifting rod is fixedly connected with a connecting plate. The bottom of the connecting plate is fixedly connected with a pressing plate. The bottom of the connecting plate is fixedly connected with a guiding rod. The surface of the guiding rod is slidably connected with a positioning sleeve.

[0006] As a further preference of this technical solution, the electric lifting rod penetrates through the mounting plate and extends to its bottom. A sliding rod is arranged at the top of the connecting plate. The sliding rod is located inside the mounting plate. The bottom of the guiding rod contacts the return spring. The positioning sleeve is fixedly connected with the support frame.

[0007] As a further preference of this technical solution, a cylinder is fixedly connected to the side of the support frame close to the control panel. The output end of the cylinder is fixedly connected with a sliding plate. The inner wall of the sliding plate is fixedly connected with a rack plate. The bottom of the sliding plate is slidably connected with a sliding seat.

[0008] As a further optimization of this technical solution, two cylinders are provided. The output rods of the two cylinders penetrate through the back surface of the support frame and extend into its interior, and the sliding seat is fixedly connected to the support frame.

[0009] As a further optimization of this technical solution, a closing gear is engaged with the side of the rack plate away from the sliding plate. The top of the closing gear is fixedly connected to a rotating plate. A guiding groove is formed at the top of the rotating plate. A moving column is slidably connected inside the guiding groove. The top of the moving column is fixedly connected to a moving plate.

[0012] The utility model provides a closing machine with precise positioning, and has the following beneficial effects:

[0013] (1) By adding a pressing component to the connecting frame in the utility model, after the product is placed into the positioning tooling, the electric lifting rod is started, so that the connecting plate drives the pressing plate to move downward. The sliding rod on the connecting plate slides in the mounting plate to ensure the stability during movement. At the same time, the guiding rod slides in the positioning sleeve and squeezes the return spring to make it contract. The elastic force of the return spring slows down the downward movement speed of the connecting plate. While the pressing plate presses and positions the product, it can play a certain protective effect. At the same time, precise positioning is achieved by the guiding rod always moving in the positioning sleeve, preventing dislocation.

[0014] (2) By starting the cylinder in the utility model, the sliding plate drives the rack plate to move on the sliding seat. Since the rack plate is engaged with the closing gear, the closing gear drives the rotating plate to rotate. The moving column slides in the guiding groove. Since the guiding groove gradually approaches the axis in the clockwise direction, the moving column drives the moving plate to slide in the sliding groove while sliding and approaches the axis of the fixed base, thereby completing the closing of the product.

[0022] The present utility model provides a technical solution: As Figure 1 and Figure 5 shown, in this embodiment, a precision positioning closing machine includes a bottom plate 1, a control panel 2 is fixedly connected to the top end of the bottom plate 1, a support frame 3 is fixedly connected to the top end of the bottom plate 1, a connecting frame 4 is fixedly connected to the top end of the support frame 3, and a pressing component 5 is fixedly connected to the side of the connecting frame 4 away from the control panel 2; the pressing component 5 includes a mounting plate 501, an electric lifting rod 502 is fixedly connected to the top end of the mounting plate 501, a connecting plate 503 is fixedly connected to the bottom end of the electric lifting rod 502, a pressing plate 504 is fixedly connected to the bottom end of the connecting plate 503, a guide rod 505 is fixedly connected to the bottom end of the connecting plate 503, a positioning sleeve 506 is slidably connected to the surface of the guide rod 505, and a return spring 507 is fixedly connected to the inner wall of the positioning sleeve 506.

[0023] After placing the product into the positioning tooling 20, start the electric lifting rod 502, so that the connecting plate 503 drives the pressing plate 504 to move downward. The sliding rod on the connecting plate 503 slides inside the mounting plate 501 to ensure the stability during movement. At the same time, the guiding rod 505 slides inside the positioning sleeve 506 and compresses the return spring 507 to make it contract. The elastic force of the return spring 507 slows down the downward movement rate of the connecting plate 503. While the pressing plate 504 presses and positions the product, it can play a certain protective role. At the same time, the guiding rod 505 always moves inside the positioning sleeve 506 to achieve precise positioning and prevent dislocation.

[0024] The electric lifting rod 502 penetrates through the mounting plate 501 and extends to its bottom end. The top end of the connecting plate 503 is provided with a sliding rod, and the sliding rod is located inside the mounting plate 501. The bottom end of the guiding rod 505 contacts the return spring 507, and the positioning sleeve 506 is fixedly connected to the support frame 3.

[0025] One side of the support frame 3 close to the control panel 2 is fixedly connected with a cylinder 6. The output end of the cylinder 6 is fixedly connected with a slide plate 7. The inner wall of the slide plate 7 is fixedly connected with a rack plate 8. The bottom end of the slide plate 7 is slidably connected with a sliding seat 9.

[0026] The number of cylinders 6 is set to two. The output rods of the two cylinders 6 penetrate through the back surface of the support frame 3 and extend to its interior, and the sliding seat 9 is fixedly connected with the support frame 3.

[0027] A closing gear 10 is engaged with one side of the rack plate 8 away from the slide plate 7. The top end of the closing gear 10 is fixedly connected with a rotating plate 11. A guiding groove 12 is opened at the top end of the rotating plate 11. A moving column 13 is slidably connected inside the guiding groove 12. The top end of the moving column 13 is fixedly connected with a moving plate 14. The top end of the moving plate 14 is fixedly connected with a closing knife 15. The top end of the closing knife 15 is fixedly connected with a guiding block 16.

[0028] The inner wall of the support frame 3 is fixedly connected with a fixed base 17. A chute 18 is opened at the top of the fixed base 17. The top end of the fixed base 17 is fixedly connected with a fixing plate 19. The top end of the fixing plate 19 is fixedly connected with the positioning tooling 20.

[0029] By starting the cylinder 6, the slide plate 7 drives the rack plate 8 to move on the sliding seat 9. Since the rack plate 8 is engaged with the closing gear 10, the closing gear 10 drives the rotating plate 11 to rotate. The moving column 13 slides inside the guiding groove 12. Since the guiding groove 12 gradually approaches the axis in the clockwise direction, the moving column 13 drives the moving plate 14 to slide inside the chute 18 and approach the axis of the fixed base 17 while sliding, thereby completing the closing of the product.

[0030] The inner wall of the fixed base 17 is fixedly connected with a compression spring 21. The top end of the compression spring 21 is fixedly connected with a pressure rod 22. The top end of the pressure rod 22 is fixedly sleeved with a positioning rod 23. The inner wall of the fixed base 17 is fixedly connected with a control switch 24.

[0031] The utility model provides a necking machine with accurate positioning, and the specific working principle is as follows:

[0032] During use, after placing the product into the positioning tooling 20, start the electric lifting rod 502 to drive the connecting plate 503 to drive the pressing plate 504 to move downward. The sliding rod on the connecting plate 503 slides in the mounting plate 501. At the same time, the guiding rod 505 slides in the positioning sleeve 506 and squeezes the return spring 507 to contract. The pressing plate 504 contacts the product and presses it tightly. At the same time, it presses the positioning rod 23 downward, so that the pressure rod 22 squeezes the compression spring 21, and the pressure rod 22 triggers the start sensor, thereby enabling the cylinder 6 to work. The cylinder 6 drives the sliding plate 7 and the rack plate 8 to move on the sliding seat 9. Since the rack plate 8 meshes with the necking gear 10, the necking gear 10 drives the rotating plate 11 to rotate. The moving column 13 slides in the guiding groove 12. Since the guiding groove 12 gradually approaches the axis in the clockwise direction, the moving column 13 drives the moving plate 14 to slide in the sliding groove 18 while sliding and approaches the axis of the fixed base 17, thereby completing the necking of the product.
