Description

Technical Field

[0001] The utility model relates to the field of stamping equipment, in particular to a clutch disc stamping device. Background Art

[0002] A clutch disc stamping device is a mechanical device designed specifically for the manufacture of clutch discs. Its core purpose is to achieve the stamping and forming of clutch discs through efficient and precise operations. The working principle of this device is based on stamping technology. During the operation of the device, the powerful pressure of the upper die is used to press the clutch disc raw material accurately placed on the lower die base, so that it is formed according to the predetermined shape and size.

[0003] During the stamping process, the force exerted by the upper die on the clutch disc material is quite large, which requires the entire device to have sufficient rigidity and stability to ensure the smooth progress of the stamping action and the quality of the finished product. However, when placing the existing clutch disc materials, most of them do not have a limiting structure. If they are not aligned with the lower die base or there is a deviation in position due to other factors, then under the action of the downward punching force of the upper die, they are likely to deviate from the original stamping trajectory, and even affect the stamping effect. For this reason, a clutch disc stamping device is proposed. Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a clutch disc stamping device. By arranging the first limiting plate at the rear end of the lower die base and making it fit with the outer wall, the rear end face of the clutch disc material is aligned with the first limiting plate to perform preliminary limiting. At the same time, after rotating to make the second limiting plate protrude from the upper surface of the lower die base and contact the front end face of the lower die base for alignment processing, further limiting is performed to prevent deviation in position due to failure to align with the lower die base or other factors, and at the same time, it also avoids affecting the original stamping trajectory of the upper stamping die.

[0005] In order to solve the above technical problems, the utility model solves the problem that the clutch disc material cannot be limited during the stamping process of the clutch disc stamping device through the following technical solutions.

[0034] Please refer to Figure 1 - Figure 7 , a clutch disc stamping device, including a stamping device frame 1 with a lower die base 101 and an upper stamping die 102. One end of the lower die base 101 is provided with a first limiting plate 2, and the other end is provided with a second limiting plate 3 for limiting. The first limiting plate 2 and the second limiting plate 3 extend towards the upper surface of the lower die base 101 and are connected by a connecting plate 4.

[0035] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7, the clutch disc stamping device of the present application is mainly composed of a stamping device frame 1, a lower die base 101, an upper stamping die 102 and other structures. Before stamping the clutch sheet on the lower die base 101, a first limit plate 2 is arranged at the rear end of the lower die base 101. The first limit plate 2 is arranged at the rear end of the lower die base 101 and fits with its outer wall. In this way, when the clutch sheet is fed onto the lower die base 101 from the front, its rear end face can be aligned with the first limit plate 2 for preliminary limiting. At the same time, since the second limit plate 3 is connected to the connecting plate 4 in a plug-in manner, after the second limit plate 3 protrudes above the upper surface of the lower die base 101 by rotation, it contacts the front end face of the lower die base 101 for alignment processing, so as to further limit the position, prevent deviation due to failure to align with the lower die base 101 or other factors, and at the same time avoid affecting the original stamping trajectory of the upper stamping die 102.

[0036] It should also be noted that the first limit plate 2 and the second limit plate 3 protrude above the upper surface of the lower die base 101. During the process of the upper stamping die 102 pressing downwards, it presses onto the clutch sheet on the lower die base 101 along the inner walls of the first limit plate 2 and the second limit plate 3. Therefore, it does not affect the overall application effect.

[0037] In the present application, a first convex layer 201 and a second convex layer 302 are also provided. Both the first convex layer 201 and the second convex layer 302 are elastic. The first convex layer 201 is fixed on the inner end face of the first limit plate 2, and the second convex layer 302 is fixed on the inner end face of the second limit plate 3. When the upper stamping die 102 presses the clutch sheet on the lower die base 101 along the first limit plate 2 or the second limit plate 3, mutual extrusion forces will be generated between the first convex layer 201 and the second convex layer 302 provided. In this way, during the complete stamping process, the connection between the two becomes tighter, thereby improving the stability during the stamping process. At the same time, for the contact with the clutch sheet, the tightness of the connection part can also be improved.

[0038] In the present application, a handle 301 and a plug-in rod 303 are also provided. The handle 301 is fixedly installed on the outer wall of the second limit plate 3 to facilitate the pulling of the overall structure of the second limit plate 3; the plug-in rod 303 and the second limit plate 3 are integrally structured. The plug-in rod 303 has a certain elasticity. After the plug-in rod 303 is inserted into the groove provided at one end of the connecting plate 4, a large frictional force is generated with the inner wall of the groove, thereby improving the connection stability between the second limit plate 3 and the connecting plate 4. At the same time, before stamping the inserted sheet, the second limit plate 3 can be rotated downwards, and after the sheet is inserted, it can be rotated back to limit the front end face of the clutch sheet, improving the operation convenience.

[0039] In this application, a stable groove 202, a positioning plate 5 and a positioning spring 501 are also provided. The stable grooves 202 are respectively opened on both sides of the first limiting plate 2, so that the connecting plate 4 can pass through and be connected to the positioning plate 5 after passing through. A plurality of positioning springs 501 are arranged between the positioning plate 5 and the first limiting plate 2. The positioning springs 501 have elasticity. During the process of moving the connecting plate 4 forward, the positioning springs 501 are squeezed, so that the interval of the sheet material limited between the second limiting plate 3 and the lower die base 101 can be adjusted and positioned.

[0040] In this application, a fastening bolt 502 is also provided. The positioning plate 5 and the connecting plate 4 are threadedly connected through the fastening bolt 502. One end of the positioning spring 501 is welded to the positioning plate 5. Therefore, after the fastening bolt 502 is disassembled, the structure on the positioning plate 5 can be removed.

[0041] In this application, a support rod 6 and a mounting sleeve 601 are also provided. The support rods 6 are fixedly installed at both ends of the bottom of the positioning plate 5, and the mounting sleeves 601 are fixedly installed at both ends of the stamping device frame 1. When applying the positioning plate 5, the support rods 6 can be first inserted into the mounting sleeves 601 correspondingly. While supporting and positioning the positioning plate 5, it is also convenient for subsequent removal and other operations.

[0042] In this application, an assembly plate member 7, a preset screw hole 701, a handle 702, an inner groove 8 and a sliding groove 801 are also provided. The assembly plate members 7 are located on both sides of the bottom of the stamping device frame 1, and a plurality of preset screw holes 701 are opened thereon. When the assembly plate member 7 is pulled out from the inner groove 8, it is fixed in the placement area of the lower die base 101, so as to improve the stability during use; the handle 702 is fixed on the outer end surface of the handle 702, so as to facilitate pulling out the assembly plate member 7; both ends of the assembly plate member 7 are provided with sliders, and both ends of the inner groove 8 are provided with sliding grooves 801 so that the sliders slide therein, so as to limit the assembly plate member 7 during its movement.

[0043] It should also be noted that the design of the inner groove 8 is to store the assembly plate member 7 when it is retracted. At the same time, when the assembly plate member 7 is pulled out to the side, its bottom is slightly higher than the bottom plate of the stamping device frame 1 and does not directly contact the placement area of the stamping device frame 1, thus avoiding the problem that it is not easy to pull out the assembly plate member 7 due to resistance.

[0044] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively realized. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the above principles, the embodiments of the present invention can have any deformation or modification.
