Description

Technical Field

[0001] This utility model relates to the field of stamping technology for semi-circular parts, and in particular to a stamping device for semi-circular parts. Background Technology

[0002] Stamping is the process of applying pressure to sheet metal, strip, tube, and profiles using stamping dies mounted on a press, causing the material to separate or plastically deform, thereby obtaining workpieces of the desired shape and size.

[0003] The stamping device used for existing semi-circular parts has an uneven force distribution in the semi-circular area due to the slow movement of the press during the stamping process. This is because the press slowly drives the stamping die to contact the sheet metal and the semi-circular die, and the stamping center is prone to deviate. As a result, the edges and corners of the parts are not completely separated from the sheet metal, which increases the wear and tear on the parts. Utility Model Content

[0004] This utility model discloses a stamping device for semi-circular parts, which aims to solve the technical problem that the existing stamping devices used for semi-circular parts cannot ensure that the edges and corners of the parts are completely separated from the sheet metal, thus increasing the wear and tear on the parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stamping device for semi-circular parts, comprising:

[0007] The stamping device body has a conveyor table on one side, a stamping table inside one side of the stamping device body, and an mounting table inside the stamping device body. Two stamping heads are fixedly connected to the bottom of the mounting table and are located above the stamping table.

[0008] The delayed ejection disconnect module is located inside the stamping head, above the stamping table;

[0009] The edge extrusion fixing module is set on the outer wall of the stamping head and located above the stamping table.

[0010] In a preferred embodiment, the delayed ejection disconnect module includes:

[0011] A support plate is installed inside the stamping head, and an electric telescopic rod is installed on one side of the mounting platform. The drive end of the electric telescopic rod is fixed to the top of the support plate.

[0012] The slide is located inside one side of the support plate. A telescopic spring is provided on one side of the slide, and one end of the telescopic spring is fixedly connected to a compression cylinder.

[0013] In a preferred embodiment, the delayed ejection disconnect module further includes:

[0014] The top plate is set on one side of the outer wall of the support plate. A connector is set inside the top plate. One end of the connector is fixedly connected to a fitting. The fitting is located above the slide.

[0015] The hydraulic rod is located on one side of the outer wall of the stamping head.

[0016] In a preferred embodiment, the delayed ejection disconnect module further includes:

[0017] The return spring has one end fixed to one end of the connector, and the other end of the return spring is provided with a push plate.

[0018] In a preferred embodiment, the edge extrusion fixing module includes:

[0019] Multiple connecting plates, with the same mounting frame on one side of two connecting plates on the same side, and the mounting frame is fixed to the outer wall of one side of the stamping head.

[0020] In a preferred embodiment, the edge extrusion fixing module further includes:

[0021] Multiple rotating shafts are respectively set inside the connecting plate. Adjusting rods are fixedly connected to the outer wall of the rotating shafts. Limiting components are fixedly connected to the side of the adjusting rods facing the stamping head.

[0022] In a preferred embodiment, the edge extrusion fixing module further includes:

[0023] A compression spring is fixed at one end to one side of the limiting member, and a compression fixing plate is fixedly connected to the other end of the compression spring. One side of the compression fixing plate is located on one side of the limiting member.

[0024] As can be seen from the above, the semi-circular part stamping device provided by this utility model adopts a symmetrical semi-circular stamping head to avoid the stamping center from deviating and causing damage to the stamped parts. At the same time, the edge extrusion and fixing module can extrude and fix the edge of the sheet metal. After stamping, the delayed ejection disconnection module uses the connector and ejection plate to ensure that the corner of each part can be completely disconnected from the sheet metal, thereby achieving the technical effect of reducing part wear.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] The semi-circular part stamping device disclosed in this utility model is mainly applied to existing stamping devices used for semi-circular parts, which cannot ensure that the edges and corners of the parts are completely separated from the sheet metal, thus increasing the wear and tear on the parts.

[0032] Reference Figures 1-4 A stamping device for semi-circular parts, comprising:

[0033] The stamping device body 2 has a conveyor table 1 on one side and a stamping table 5 inside one side of the stamping device body 2. The stamping device body 2 also has an installation table 7 inside. Two stamping heads 4 are fixedly connected to the bottom of the installation table 7 and are located above the stamping table 5.

[0034] The delayed ejection disconnect module 3 is located inside the stamping head 4 and above the stamping table 5;

[0035] The edge extrusion fixing module 6 is disposed on the outer wall of the stamping head 4 and located above the stamping table 5.

[0036] The device uses a symmetrical semi-circular punch head 4 to avoid damage to the stamping parts caused by deviation of the punching center. At the same time, the edge extrusion and fixing module 6 can extrude and fix the edge of the sheet metal. After the stamping is completed, the delayed ejection disconnection module 3 uses the connector 307 and the ejection plate 310 to ensure that the corner of each part can be completely disconnected from the sheet metal, reducing the wear and tear of the parts.

[0037] Reference Figure 1 , Figure 2 and Figure 3In a preferred embodiment, the delayed ejection disconnection module 3 includes:

[0038] A support plate 302 is installed inside the stamping head 4. An electric telescopic rod 301 is installed on one side of the mounting platform 7. The drive end of the electric telescopic rod 301 is fixed to the top of the support plate 302.

[0039] The slide 303 is located inside one side of the support plate 302. A telescopic spring 305 is provided on one side of the slide 303, and a compression cylinder 304 is fixedly connected to one end of the telescopic spring 305.

[0040] In this solution, the delayed ejection disconnection module 3 also includes:

[0041] The top plate 311 is disposed on one side of the outer wall of the support plate 302. A connector 307 is disposed inside the top plate 311. One end of the connector 307 is fixedly connected to a fitting 306, which is located above the slide block 303.

[0042] Hydraulic rod 308 is installed on one side of the outer wall of the stamping head 4.

[0043] In this solution, the delayed ejection disconnection module 3 also includes:

[0044] The reset spring 309 has one end fixed to one end of the connector 307, and the other end of the reset spring 309 is provided with an ejector plate 310.

[0045] Specifically, the delayed ejection disconnection module 3 can eject the parts after stamping to ensure that the edges and corners of each part can be completely disconnected from the sheet metal, thereby reducing part wear.

[0046] The return spring 309 uses its own elasticity to reset the ejector plate 310 after it has been ejected.

[0047] Reference Figure 1 and Figure 4 In a preferred embodiment, the edge compression fixing module 6 includes:

[0048] Multiple connecting plates 602, with the same mounting frame 601 on one side of two connecting plates 602 on the same side, and the mounting frame 601 is fixed to the outer wall of one side of the stamping head 4.

[0049] In this solution, the edge extrusion fixing module 6 also includes:

[0050] Multiple rotating shafts 603 are respectively disposed inside the connecting plate 602. An adjusting rod 604 is fixedly connected to the outer wall of the rotating shaft 603. A limiting member 605 is fixedly connected to the side of the adjusting rod 604 facing the stamping head 4.

[0051] In this solution, the edge extrusion fixing module 6 also includes:

[0052] A compression spring 606 has one end fixed to one side of a limiting member 605, and the other end of the compression spring 606 is fixedly connected to a compression fixing plate 607, with one side of the compression fixing plate 607 located on one side of the limiting member 605.

[0053] Specifically, the compression spring 606 can utilize its own elasticity to allow the compression fixing plate 607 to adapt to plates of different thicknesses and widths;

[0054] The extrusion fixing plate 607 descends to the surface of the sheet and applies pressure to it, thereby fixing the edge of the sheet and preventing the sheet from shifting during stamping and damage to the accessories.

[0055] Working principle: When the device is working, the edge extrusion fixing module 6 moves together with the punch head 4 until the extrusion fixing plate 607 contacts the surface of the sheet. At this time, the extrusion fixing plate 607 achieves the fixing effect on the edge of the sheet. As the punch head 4 is lowered, the sheet causes the adjusting rod 604 and the rotating shaft 603 to rotate, so as to adjust the angle and fixing force.

[0056] After stamping is completed, the electric telescopic rod 301 is activated, which moves the support plate 302 inside the top plate 311. When the support plate 302 moves the slide 303 to the same side as the hydraulic rod 308 on one side of the stamping head 4, the hydraulic rod 308 is activated. The hydraulic rod 308 pushes the extrusion cylinder 304 and the telescopic spring 305 to move, so that the slide 303 moves above the support plate 302, and the mating part 306 is located inside the slide 303. At this time, the hydraulic rod 308 retracts, the telescopic spring 305 moves inside the stamping head 4, and the mating part 306 is fixed inside the slide 303. The electric telescopic rod 301 continues to move the support plate 302, so that the connecting part 307 overcomes the elasticity of the return spring 309 and drives the ejector plate 310 to move, so that the corner of the accessory can be completely separated from the sheet metal.

[0057] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
