Description

Technical Field

[0001] This application relates to the field of punch press technology, and in particular to an automated punch press unloading device. Background Technology

[0002] A punch press is a type of equipment used for processing holes of various sizes and shapes on equipment panels, electrical component mounting plates, metal furniture, kitchenware, and cabinets.

[0003] In related technologies, in traditional punch press unloading operations, the unloading process relies heavily on manual operation. Workers need to frequently remove the stamped material plates from the stamping die base and frequently put the material plates to be stamped back on the stamping die base. This operation method not only consumes a lot of manpower, but also has low work efficiency and is difficult to meet the needs of large-scale, high-efficiency production.

[0004] Therefore, we propose an automated punch press unloading device to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide an automated punch press unloading device that integrates automatic feeding and unloading of material plates, reducing manual intervention, minimizing labor, and significantly improving work efficiency.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: an automated punch press unloading device, comprising a machine base and a punch press body, a material plate holding box, and a stamping die base mounted and fixed on the machine base. The punch press body is fixedly mounted on the top of the machine base, and a hydraulic cylinder is fixedly mounted on the punch press body. A punch head is fixedly mounted on the output end of the hydraulic cylinder. The stamping die base is located below the punch head. The material plate holding box contains several stacked material plates, and a plate discharge port is opened on the bottom left side of the material plate holding box. An automatic unloading device is provided on the machine base. The material handling mechanism, or automatic unloading mechanism, includes a base, an electric telescopic rod one, a longitudinal beam one, an L-shaped positioning plate, an electric telescopic rod two, and a rubber pressure plate. The base is fixedly installed on the top of the machine platform and located behind the stamping die base. The electric telescopic rod one is fixedly installed on the top of the base. The longitudinal beam one is fixedly installed on the output end of the electric telescopic rod one. The L-shaped positioning plate is fixedly installed on the front end of the longitudinal beam one and located on the left side of the stamping die base. The electric telescopic rod two is fixedly installed on the top inner wall of the L-shaped positioning plate. The rubber pressure plate is fixedly installed on the output end of the electric telescopic rod two.

[0007] By adopting the above technical solution, the telescopic feature of the first electric telescopic rod can be used to control the horizontal linear movement of the first longitudinal beam, so that the L-shaped positioning plate follows the horizontal linear movement of the first longitudinal beam. The telescopic feature of the second electric telescopic rod can be used to control the vertical movement of the rubber pressing plate. The rubber pressing plate can firmly press the material plate onto the stamping die base, ensuring that the material plate will not move during the stamping process. After the stamping is completed, by controlling the extension of the first electric telescopic rod, the friction generated by the rubber pressing plate pressing the material plate can drive the material plate to gradually move to the left out of the stamping die base, realizing the function of automatic unloading.

[0008] A further feature of this application is that the left side of the stamping die base is provided with a clearance groove with an open top, and the bottom of the L-shaped positioning plate is located in the clearance groove.

[0009] By adopting the above technical solution, when the bottom of the L-shaped positioning plate abuts against the clearance groove, the position of the material plate placed on the stamping die base can be accurately positioned, so that it maintains the accurate position during the stamping process.

[0010] A further feature of this application is that the bottom surface of the rubber pressure plate is provided with anti-slip texture.

[0011] By adopting the above technical solution, the anti-slip texture design can effectively increase the friction between the rubber pressing plate and the material plate, prevent the material plate from sliding or shifting during pressing and unloading, and ensure the smooth progress of unloading operations.

[0012] A further configuration of this application is as follows: the automatic unloading mechanism further includes a second longitudinal beam, a connecting rod, a vertical plate, and a push plate. The second longitudinal beam is fixedly installed on the rear side wall of the L-shaped positioning plate and is located above the first longitudinal beam. The connecting rod is located behind the material plate container and is fixedly connected to the second longitudinal beam at one end. The vertical plate is fixedly installed on the other end of the connecting rod and is located on the right side of the material plate container. The push plate is fixedly installed on the right side wall of the vertical plate. A push plate opening is provided at the bottom right side of the material plate container, and the left end of the push plate moves through the push plate opening.

[0013] By adopting the above technical solution, during the automatic unloading process of the stamped material plate, the L-shaped positioning plate will drive the connecting rod to move to the left, and the vertical plate and push plate will follow the connecting rod to move to the left. At this time, the push plate can push the bottom material plate in the material plate container out of the plate outlet, so that the pushed material plate gradually moves to the stamping die base, completing the automatic feeding.

[0014] A further feature of this application is that a horizontal guide rod located above the push plate is fixedly installed on the right outer wall of the material plate container, and the vertical plate is slidably mounted on the horizontal guide rod.

[0015] By adopting the above technical solution, the sliding cooperation between the horizontal guide rod and the vertical plate provides stable guidance for the pushing action of the push plate.

[0016] A further provision of this application is that a limit stop is fixedly installed at the right end of the horizontal guide rod.

[0017] By adopting the above technical solution, the design of the limit block can prevent the vertical plate from sliding out of the horizontal guide rod, avoid structural failure, and ensure the continuous and stable operation of the unloading process.

[0018] A further feature of this application is that a discharge channel is provided on the top left side of the machine tool, and the bottom inner wall of the discharge channel is an inclined surface structure.

[0019] By adopting the above technical solution, during the automatic unloading process of the stamped material plate, the material plate will fall into the unloading channel under its own weight and slide out automatically along its inclined surface.

[0020] A further provision of this application is that: a clearance hole is provided on the top of the stamping die base, the clearance hole is located directly below the punch, a waste receiving groove is provided on the front side wall of the machine base, a waste falling hole is provided on the top inner wall of the waste receiving groove, and the waste falling hole is connected to the clearance hole.

[0021] By adopting the above technical solutions, the design of the clearance hole can prevent the punch from contacting the stamping die base, ensuring the smooth progress of the stamping operation. The design of the scrap drop hole can guide the scrap generated by stamping to the scrap receiving tank for temporary storage.

[0022] A further provision of this application is that a waste collection box is placed inside the waste receiving trough.

[0023] By adopting the above technical solution, the waste collection box is designed to collect and hold waste generated during stamping.

[0024] A further feature of this application is that two limiting strips are fixedly installed on the top of the stamping die base, and the right ends of the limiting strips are fixedly connected to the left outer wall of the material plate container, with the plate outlet located between the two limiting strips.

[0025] By adopting the above technical solution, the design of the two limiting strips not only guides the material plate during the automatic feeding process, but also further limits the position of the material plate, ensuring the accuracy and consistency of stamping, thereby improving product quality.

[0026] This application includes at least one of the following beneficial technical effects:

[0027] 1. This application is equipped with an automatic unloading mechanism, which can realize the integrated operation of automatic feeding and unloading of material plates, reduce manual intervention, reduce manual labor, and greatly improve work efficiency.

[0028] 2. This application sets two limit bars and an L-shaped positioning plate, and uses them in conjunction with the clearance groove to accurately position the material plate loading position, ensure accurate stamping position, improve product quality, and thus ensure the consistency of the stamping position of each material plate when batch stamping material plates.

[0029] 3. In this application, the waste generated by stamping can automatically fall into the waste collection box through the clearance hole and waste drop hole, which facilitates the centralized cleaning of waste, maintains a clean working environment, and also prevents waste from affecting the normal operation of the equipment.

[0036] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] See Figures 1-5This application provides an automated punch press unloading device, including a machine base 1 and a punch press body 2, a material plate holding box 3, and a stamping die base 4, which are installed and fixed on the machine base 1. The punch press body 2 is fixedly installed on the top of the machine base 1. A hydraulic cylinder 5 is fixedly installed on the punch press body 2. A punch 6 is fixedly installed at the output end of the hydraulic cylinder 5. The stamping die base 4 is located below the punch 6. The upper surface of the stamping die base 4 is a smooth surface. The material plate holding box 3 contains a number of stacked material plates. A plate outlet 7 is opened at the bottom left side of the material plate holding box 3. The inner height of the plate outlet 7 is set to 1.2-1.5 times the thickness of the material plate, so as to ensure that only one material plate can be pushed out at a time. The upper surface of the stamping die base 4 is flush with the bottom inner wall of the plate outlet 7.

[0038] In this embodiment, an automatic unloading mechanism is provided on the machine base 1. The automatic unloading mechanism includes a pad 8, an electric telescopic rod 9, a longitudinal beam 10, an L-shaped positioning plate 11, an electric telescopic rod 12, and a rubber pressure plate 13. The pad 8 is fixedly installed on the top of the machine base 1 and located behind the stamping die base 4. The electric telescopic rod 9 is fixedly installed on the top of the pad 8. The longitudinal beam 10 is fixedly installed on the output end of the electric telescopic rod 9. The L-shaped positioning plate 11 is fixedly installed on the front end of the longitudinal beam 10 and located on the left side of the stamping die base 4. The electric telescopic rod 12 is fixedly installed inside the top of the L-shaped positioning plate 11. On the wall, a rubber pressure plate 13 is fixedly installed at the output end of the electric telescopic rod 12. The bottom surface of the rubber pressure plate 13 is provided with anti-slip texture. Utilizing the telescopic feature of the electric telescopic rod 12, the rubber pressure plate 13 can be controlled to move vertically. The rubber pressure plate 13 can be used to firmly press the material plate onto the stamping die 4. During the stamping process, it can be ensured that the material plate will not move. After the stamping is completed, by controlling the extension of the electric telescopic rod 9, under the action of the friction generated by the rubber pressure plate 13 pressing the material plate, the material plate can be driven to gradually move to the left out of the stamping die 4, realizing automatic unloading.

[0039] In this embodiment, the automatic unloading mechanism further includes a second longitudinal beam 15, a connecting rod 16, a vertical plate 17, and a push plate 18. The second longitudinal beam 15 is fixedly installed on the rear side wall of the L-shaped positioning plate 11, and is located above the first longitudinal beam 10. The connecting rod 16 is located behind the material plate holding box 3, and one end of the connecting rod 16 is fixedly connected to the second longitudinal beam 15. The vertical plate 17 is fixedly installed on the other end of the connecting rod 16, and is located on the right side of the material plate holding box 3. The push plate 18 is fixedly installed on the vertical plate 17. On the right side wall, a push plate opening 19 is provided at the bottom right side of the material plate holding box 3. The left end of the push plate 18 moves through the push plate opening 19. During the automatic unloading of the stamped material plate, the L-shaped positioning plate 11 will drive the connecting rod 16 to move to the left. The vertical plate 17 and the push plate 18 will follow the connecting rod 16 to move to the left. At this time, the push plate 18 can push the bottom material plate in the material plate holding box 3 out of the plate outlet 7, so that the pushed material plate gradually moves to the stamping die base 4, completing the automatic feeding.

[0040] In this embodiment, a clearance groove 14 with an open top is provided on the left side of the stamping die base 4. The bottom of the L-shaped positioning plate 11 is located in the clearance groove 14. Two limiting strips 27 are fixedly installed on the top of the stamping die base 4. The right ends of the limiting strips 27 are fixedly connected to the left outer wall of the material plate holding box 3. The plate outlet 7 is located between the two limiting strips 27. By using the bottom of the L-shaped positioning plate 11 to abut against the clearance groove 14, the loading position of the material plate can be accurately positioned. By using the two limiting strips 27, the loading process of the material plate can be guided during the automatic loading process, and the position of the material plate can be further limited to prevent the material plate from shifting. Thus, when batch stamping material plates, the consistency of the stamping position of each material plate can be guaranteed.

[0041] In this embodiment, a horizontal guide rod 20 located above the push plate 18 is fixedly installed on the right outer wall of the material plate container 3. The vertical plate 17 is slidably mounted on the horizontal guide rod 20. A limit stop 21 is fixedly installed at the right end of the horizontal guide rod 20 to ensure the stable pushing action of the push plate 18.

[0042] In this embodiment, a discharge channel 22 is provided on the top left side of the machine 1. The bottom inner wall of the discharge channel 22 is an inclined surface structure. During the automatic discharge of the stamped material plate, the material plate will fall into the discharge channel 22 under its own weight and slide out automatically along its inclined surface. The whole process does not require much manual intervention, which greatly improves the discharge efficiency and reduces labor costs.

[0043] In this embodiment, a clearance hole 23 is provided on the top of the stamping die base 4. The clearance hole 23 is located directly below the punch 6. A waste receiving groove 24 is provided on the front side wall of the machine base 1. A waste falling hole 25 is provided on the top inner wall of the waste receiving groove 24. The waste falling hole 25 is connected to the clearance hole 23. A waste collection box 26 is placed in the waste receiving groove 24, which allows the waste generated during the stamping process to fall directly into the waste collection box 26 through the clearance hole 23 and the waste falling hole 25, which is convenient for centralized cleaning, keeps the working environment clean, and also avoids the accumulation of waste from affecting the normal operation of the equipment.

[0044] In this embodiment, it should be noted that a controller is installed and fixed on the front side wall of the machine base 1. The controller is equipped with multiple control buttons. The punch press body 2, electric telescopic rod 1 9, electric telescopic rod 2 12 and the controller are electrically connected. The multiple control buttons can be used to control the operation of the punch press body 2, electric telescopic rod 1 9 and electric telescopic rod 2 12 respectively. Since the wiring connection method and control method are mature technologies in this field and have been fully disclosed, they will not be described in detail here.

[0045] With the above structure, the working principle of the automated punch press unloading device provided in this application is as follows:

[0046] Several material plates are stacked neatly and placed in the material plate holding box 3. When feeding is required, the electric telescopic rod 9 is extended. The output end of the electric telescopic rod 9 drives the longitudinal beam 10, L-shaped positioning plate 11, longitudinal beam 15, connecting rod 16, vertical plate 17 and push plate 18 to move horizontally to the left. At this time, the push plate 18 pushes the bottom material plate in the material plate holding box 3 to be gradually pushed out from the plate outlet 7. Under the guidance of the two limit strips 27, the pushed material plate is accurately guided to the top of the stamping die base 4. When the left side of the pushed material plate is above the clearance groove 14, Then, control the electric telescopic rod 9 to retract and reset. The output end of the electric telescopic rod 9 drives the longitudinal beam 10, L-shaped positioning plate 11, longitudinal beam 15, connecting rod 16, vertical plate 17 and push plate 18 to move horizontally to the right. At this time, the push plate 18 gradually moves out of the material plate container 3. When the bottom of the L-shaped positioning plate 11 enters the clearance groove 14, it will abut against the left side of the material plate, thus pushing the material plate back to the right a little until the bottom of the L-shaped positioning plate 11 abuts against the right inner wall of the clearance groove 14. Then, stop the electric telescopic rod 9, thus completing the automatic and precise feeding of the material plate.

[0047] Next, by controlling the extension of the electric telescopic rod 12, the rubber pressure plate 13 can be moved vertically downward. The rubber pressure plate 13 can press the material plate onto the stamping die base 4. Then, by controlling the extension of the hydraulic cylinder 5 on the main body of the punch press 2, the punch 6 can be driven to move downward, and the material plate can be stamped. By pressing the material plate onto the stamping die base 4 with the rubber pressure plate 13, it can be ensured that the material plate will not shift during the stamping process, thus ensuring the stamping quality.

[0048] During the stamping process, the waste generated falls into the waste collection box 26 in the waste receiving groove 24 through the clearance hole 23 and the waste falling hole 25, thereby collecting the waste.

[0049] After the material is stamped, the hydraulic cylinder 5 is controlled to retract and reset, so that the punch 6 rises back to its original position. Then, the electric telescopic rod 9 is controlled to extend and run. The output end of the electric telescopic rod 9 drives the longitudinal beam 10, L-shaped positioning plate 11, longitudinal beam 15, connecting rod 16, vertical plate 17 and push plate 18 to move horizontally to the left. At this time, under the action of the friction generated by the rubber holding plate 13 pressing the material plate, the stamped material plate can be driven to gradually move to the left out of the stamping die base 4, realizing automatic unloading. Under the action of its own weight, the stamped material plate falls into the unloading channel 22 and slides out automatically along its inclined surface.

[0050] During the automatic unloading process of the stamped material plate, as the pusher plate 18 moves to the left, the bottom material plate in the material plate container 3 can be pushed out from the outlet 7 by the pusher plate 18, so that the pushed material plate gradually moves to the stamping die base 4 and continues to be automatically fed. According to the above operation steps, the automatic feeding, stamping and automatic unloading of the material plate can be integrated, which greatly improves the work efficiency.
