Description

Technical Field

[0001] This utility model relates to the field of stamping processing technology, and in particular to a quick die changing device for stamping dies. Background Technology

[0002] In the production of automotive parts, stamping dies are essential equipment. Stamping dies mainly use physical impact to change the shape of materials. Stamping dies are usually moved from the upper die to the lower die by a hydraulic cylinder, so that the material between the upper and lower dies will undergo a certain shape change under pressure.

[0003] Currently, the dies on stamping equipment are generally fixed by multiple bolts, which makes the assembly and disassembly of the dies relatively slow. Furthermore, if the bolt heads rust, it will make die replacement even more troublesome. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a quick die changing device for stamping dies, which aims to improve the problem that dies on traditional stamping devices are generally fixed by multiple bolts, resulting in slow assembly and disassembly of dies on stamping devices, and that once the bolt heads rust, die replacement becomes even more troublesome.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick die-changing device for stamping dies, comprising a support plate, a motor fixedly mounted on the top of the support plate, a rotating column fixedly mounted on the output end of the motor, a connecting block 1 symmetrically fixedly connected to the outer wall of the rotating column, a rotating shaft 2 rotatably connected to one end of the connecting block 1, a connecting block 2 fixedly connected to the outer wall of the rotating shaft 2, a rotating shaft 3 fixedly connected to one end of the connecting block 2, a slider rotatably connected to one end of the rotating shaft 3, a baffle slidably connected to one side of the slider, a clamping plate fixedly connected to the other side of the slider, a limit rod slidably connected inside the clamping plate, a worktable fixedly connected to the bottom of the limit rod, and a transport structure symmetrically arranged on the top of the worktable.

[0006] By adopting the above technical solution, the rotating column is driven by a motor to rotate, which in turn drives the linkage mechanism composed of connecting block one, rotating shaft two, and connecting block two to move. The rotational connection between rotating shaft three and the slider converts the oscillation into linear motion, causing the slider to move along the baffle groove. Finally, the clamping plate fixedly connected to the slider slides along the limiting rod in a directional manner, thereby achieving stable clamping. Through this mechanical transmission method, the mold is fixed, thus improving the problem that molds on traditional stamping devices are generally fixed by multiple bolts, resulting in slow mold assembly and disassembly, and the mold replacement becomes more troublesome once the bolt heads rust.

[0007] Preferably, the transport structure includes a support column, and a limit block is fixedly connected to the top of the support column.

[0008] Preferably, the support column is rotatably connected to a rotating shaft, and a roller is fixedly connected to the outer wall of the rotating shaft.

[0009] Preferably, one end of the support column is fixedly connected to one side of the workbench, and rollers are evenly installed inside the workbench.

[0010] Preferably, a rotating shaft is fixedly connected inside the roller two, and the rotating shaft is rotatably connected inside the worktable.

[0011] Preferably, the bottom of the support column is symmetrically and fixedly connected with a second support leg, and the bottom of the workbench is symmetrically and fixedly connected with a first support leg.

[0012] Preferably, a connecting block three is fixedly connected to the outer wall of one of the supporting legs.

[0013] Preferably, one end of the connecting block three is fixedly connected to one side of the baffle.

[0014] This utility model has the following beneficial effects: 1. In this utility model, a rotating column is driven by a motor to rotate, which in turn drives the linkage mechanism composed of connecting block one, rotating shaft two, and connecting block two to move. The rotational connection between rotating shaft three and the slider converts the oscillation into linear motion, causing the slider to move along the baffle groove. Finally, the clamping plate fixedly connected to the slider slides along the limiting rod in a directional manner, thereby achieving stable clamping. Through this mechanical transmission method, the mold is fixed, thus improving the problem that molds on traditional stamping devices are generally fixed by multiple bolts, resulting in slow mold assembly and disassembly.

[0015] In this invention, the first rotating shaft drives the first roller and the second rotating shaft to rotate, thereby realizing the rolling conveying of the mold on the support column and the top of the worktable. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] Reference Figures 1-3 An embodiment of this utility model provides a quick die changing device for stamping dies, comprising a support plate 1, a motor 2 fixedly mounted on the top of the support plate 1, a rotating column 3 fixedly mounted on the output end of the motor 2, connecting blocks 1 5 symmetrically fixedly connected to the outer wall of the rotating column 3, a rotating shaft 2 6 rotatably connected to one end of the connecting blocks 1 5, a connecting block 2 7 fixedly connected to the outer wall of the rotating shaft 2 6, a rotating shaft 3 8 fixedly connected to one end of the connecting blocks 2 7, a slider 9 rotatably connected to one end of the rotating shaft 3 8, a baffle 4 slidably connected to one side of the slider 9, a clamping plate 10 fixedly connected to the other side of the slider 9, a limit rod 18 slidably connected inside the clamping plate 10, a worktable 11 fixedly connected to the bottom of the limit rod 18, and a transport structure symmetrically arranged on the top of the worktable 11.

[0019] Specifically, when motor 2 starts, the output end of motor 2 drives the rotating column 3 to rotate. Since the rotating column 3 and connecting block 5 are fixedly connected, the rotating column 3 drives the connecting block 5 to rotate. Then, the connecting block 5 forms a rotational connection with the connecting block 7 through the rotating shaft 6. The swing of the connecting block 5 drives the connecting block 7 to swing synchronously. The connecting block 7 and the rotating shaft 8 are fixedly connected, so the connecting block 7 drives the rotating shaft 8 to swing. Since the rotating shaft 8 and the slider 9 are rotatably connected, and the slider 9 and the baffle 4 are slidably connected, the baffle 4 has a groove inside. The rotating shaft 8 pushes the slider 9 to move linearly along the groove of the baffle 4. The slider 9 and the clamping plate 10 are fixedly connected, so the slider 9 drives the clamping plate 10 to slide. The limiting rod 18 and the worktable 11 are fixedly connected, so that the clamping plate 10 can achieve clamping movement above the worktable 11. The rotating column 3 is driven by motor 2 to rotate, which in turn drives the linkage mechanism composed of connecting block 5, rotating shaft 6, and connecting block 7. The rotational connection between rotating shaft 8 and slider 9 converts the oscillation into sliding, causing slider 9 to slide along the groove of baffle 4. Finally, it drives clamping plate 10, which is fixedly connected to slider 9, to slide in a direction along limiting rod 18, thereby achieving stable clamping of the mold. Restarting the motor and releasing the clamping plate allows for quick demolding. This mechanical transmission method achieves mold fixation, thus improving the problem that molds on traditional stamping devices are generally fixed by multiple bolts, resulting in slow mold assembly and disassembly.

[0020] Reference Figures 1-4 The transport structure includes a support column 14, a limit block 15 fixedly connected to the top of the support column 14, a rotating shaft 13 rotatably connected inside the support column 14, a roller 12 fixedly connected to the outer wall of the rotating shaft 13, one end of the support column 14 fixedly connected to one side of the workbench 11, rollers 16 evenly installed inside the workbench 11, a rotating shaft fixedly connected inside the rollers 16, and the rotating shaft rotatably connected inside the workbench 11.

[0021] Specifically, when the mold needs to be installed, a crane is used to place the mold on top of the support column 14. The mold is slowly pushed to rotate the rotating shaft 13. The rotating shaft 13 and roller 12 are fixedly connected. The rotating shaft 13 drives the roller 12 to rotate, thus moving the mold. The worktable 11 and the support column 14 are fixedly connected, and the support column 14 and the limiting block 15 are fixedly connected. The limiting block 15 limits the mold. The interior of the worktable 11 is rotatably connected to the interior of the roller 16. The rotation of the roller 16 inside the worktable 11 moves the mold. The rotation of the rotating shaft 13, which drives the roller 12, and the rotating shaft, which drives the roller 16, achieves the rolling conveying of the mold on the support column 14 and the top of the worktable 11.

[0022] Reference Figures 1-3Support legs 20 are symmetrically fixedly connected to the bottom of support column 14, and support legs 19 are symmetrically fixedly connected to the bottom of worktable 11. Connecting block 3 17 is fixedly connected to the outer wall of support leg 19, and one end of connecting block 3 17 is fixedly connected to one side of baffle 4.

[0023] Specifically, since the workbench 11 and support leg 19 are fixedly connected, support leg 19 provides support for the workbench 11. Similarly, support column 14 and support leg 20 are fixedly connected, providing support for support column 14. One side of support leg 19 is fixedly connected to connecting block 3 17, and connecting block 3 17 is fixedly connected to baffle 4, thus support leg 19 provides fixed support to baffle 4 via connecting block 3 17. Support legs 19 and 20 provide independent support for the workbench 11 and support column 14 respectively, while support leg 19 establishes a rigid connection with baffle 4 via connecting block 3 17, thereby providing a stable support foundation for the entire system.

[0024] Working principle: When the mold needs to be installed, a crane is used to place the mold on top of the support column 14. The mold is slowly pushed to rotate the rotating shaft 13, which in turn drives the roller 12 to rotate, thus moving the mold. The rotation of the roller 2 16 inside the worktable 11 also drives the mold. When the motor 2 starts, the output of the motor 2 drives the rotating column 3 to rotate, which in turn drives the connecting block 5 to rotate. The swing of the connecting block 5 then drives the connecting block 7 to swing synchronously, which in turn drives the rotating shaft 3 8 to swing. The rotating shaft 3 8 then pushes the slider 9 to move linearly along the groove of the baffle 4, thus... The slider 9 drives the clamping plate 10 to slide, so that the clamping plate 10 can achieve clamping motion above the worktable 11. The motor 2 drives the rotating column 3 to rotate, which in turn drives the linkage mechanism composed of connecting block 5, rotating shaft 6 and connecting block 7 to move. The rotating shaft 8 and the slider 9 are connected to the rotation, which converts the swing into sliding, so that the slider 9 slides along the slide groove of the baffle 4. Finally, the clamping plate 10 is driven to slide in a direction along the limiting rod 18, thereby achieving stable clamping. Then the first support leg 19 provides support to the worktable 11, the second support leg 20 provides support to the support column 14, and the first support leg 19 provides fixed support to the baffle 4 through the connecting block 3 17.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
