Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die fixing fixture. Background Technology
[0002] In the traditional metal processing and manufacturing field, stamping dies are key tools for achieving efficient metal sheet forming, and their fixing method plays a decisive role in the precision, efficiency, and safety of stamping production. Stamping dies must be precisely and securely fixed on the stamping machine to withstand the enormous impact and pressure during the stamping process.
[0003] As a core component of stamping processes, the method of fixing stamping dies directly affects the quality of stamped products, production efficiency, and equipment safety. Currently, the common method for fixing stamping dies is to fit the die onto the sleeve shaft on the machine tool table by making holes at its four corners, and then securing it with nuts. This fixing method has the advantages of simple structure and convenient operation, and is widely used in small and medium-sized manufacturing enterprises and some production scenarios where the requirements for stamping precision are relatively low.
[0004] As described in the prior art, during the process of fixing the stamping die, it is convenient to position and install the stamping die. The diameter of the hole opened on it generally needs to be slightly larger than the diameter of the hole of the sleeve shaft to facilitate the smooth insertion of the stamping die. Then, it is locked by the nut and the threaded groove opened on the outside of the sleeve shaft. However, this fixing method has a drawback. Although the nut fixes the stamping die by locking it downwards, and the stamping die cannot move up and down, there will be a certain gap between the opening of the stamping die and the sleeve shaft. However, the friction generated between the nut and the stamping die cannot guarantee that the stamping die will not shift. This will cause the stamping die to shift to a certain extent during the stamping process of the stamping press stamping part on the stamping die. Now, there is a need for a fixing fixture that can solve the problem of the gap defect between the mounting hole and the sleeve shaft while fixing the stamping die. Utility Model Content
[0005] The purpose of this utility model is to provide a stamping die fixing fixture to solve the above-mentioned shortcomings in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a stamping die fixing fixture, including a stamping machine, a stamping platform fixedly installed on the stamping machine, and a stamping die body. A sleeve shaft is fixedly installed at the top of the stamping platform. The sleeve shaft is hollow. The stamping die body has multiple mounting holes. The multiple mounting holes on the stamping die body are sleeved on the sleeve shaft. A fixing component is installed at the top of the sleeve shaft. A trigger abutment component is provided inside the sleeve shaft.
[0007] As a further description of the above technical solution: the sleeve shaft is provided with a threaded groove, and the fixing component includes a fixing cylinder, which is threadedly connected to the sleeve shaft through the threaded groove.
[0008] As a further description of the above technical solution: a pressure ring is fixedly installed at the bottom end of the fixed cylinder, and the pressure ring presses against the surface of the stamping die body.
[0009] As a further description of the above technical solution: the trigger abutment assembly includes four abutment blocks that are slidably installed on the side wall of the sleeve shaft, a connecting rod is fixedly installed inside the fixed cylinder, and a trigger block is fixedly installed at the bottom end of the connecting rod.
[0010] As a further description of the above technical solution: the abutment block is provided with a wedge-shaped surface at one end inside the sleeve shaft, and the bottom end of the trigger block is provided with four abutment surfaces. The four abutment surfaces and the trigger block form a quadrangular frustum shape, and the four abutment surfaces correspond to the four wedge-shaped surfaces.
[0011] As a further description of the above technical solution: two limiting members are fixedly installed on each of the plurality of abutting blocks, and the two limiting members are respectively sleeved on the abutting block of the inner section and the abutting block of the outer section of the sleeve shaft.
[0012] This utility model provides a stamping die fixing fixture. It has the following beneficial effects: When it is necessary to install a stamping die, the stamping die body is sleeved on multiple sleeve shafts, and the stamping die body is locked by a fixing component. During the locking process, the gap between the sleeve shaft and the mounting hole can be compensated by triggering the abutment component, thereby achieving downward pressing and fixing of the stamping die body, while limiting the stamping die body in the plane and preventing the stamping die body from shifting.
[0013] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0023] 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.
[0024] Reference Figure 1-6 A stamping die fixing fixture includes a stamping machine 1, a stamping platform 2 fixedly mounted on the stamping machine 1, and a stamping die body 3. A sleeve shaft 4 is fixedly mounted on the top of the stamping platform 2. The sleeve shaft 4 is hollow. The stamping die body 3 has multiple mounting holes 6, which are fitted onto the sleeve shaft 4. A fixing component is mounted on the top of the sleeve shaft 4, and a trigger abutment component is provided inside the sleeve shaft 4. When it is necessary to install the stamping die, the stamping die body 3 is fitted onto the multiple sleeve shafts 4, and the stamping die body 3 is locked by the fixing component. During the locking process, the trigger abutment component can compensate for the gap between the sleeve shaft 4 and the mounting holes 6, thereby achieving downward pressing and fixing of the stamping die body 3, while limiting the stamping die body 3 in the plane and preventing the stamping die body 3 from shifting.
[0025] It is worth mentioning that the position of the sleeve shaft is offset from the stamping device of the upper stamping machine. During the downward stamping process, the stamping device will only stamp the effective stamping area in the middle of the stamping die body. The sleeve shaft is set at the edge of the die and will not affect the stamping device above.
[0026] As a preferred technical solution of this embodiment, the sleeve shaft 4 is provided with a threaded groove 5, and the fixing component includes a fixing cylinder 7, which is threadedly connected to the sleeve shaft 4 through the threaded groove 5; the opening of the threaded groove 5 can facilitate the fixing between the fixing cylinder 7 and the sleeve shaft 4.
[0027] As a preferred technical solution in this embodiment, a pressure ring 8 is fixedly installed at the bottom end of the fixed cylinder 7, and the pressure ring 8 presses against the surface of the stamping die body 3; after the fixed cylinder 7 is screwed downward, the pressure ring 8 can press and fix the stamping die body 3.
[0028] As a preferred technical solution of this embodiment, the trigger abutment assembly includes four abutment blocks 11 slidably mounted on the side wall of the sleeve shaft 4. A connecting rod 9 is fixedly mounted inside the fixed cylinder 7, and a trigger block 10 is fixedly mounted at the bottom end of the connecting rod 9. When the fixed cylinder 7 is rotated downward, the trigger block 10 below the connecting rod 9 can push the four abutment blocks 11 outward, so that the four abutment blocks 11 abut against the inner wall of the mounting hole 6, thereby compensating for the gap between the mounting hole 6 and the sleeve shaft 4.
[0029] As a preferred technical solution of this embodiment, the abutment block 11 is provided with a wedge-shaped surface 13 at one end inside the sleeve shaft 4, and the bottom end of the trigger block 10 is provided with four abutment surfaces 14. The four abutment surfaces 14 and the trigger block 10 form a quadrangular frustum shape, and the four abutment surfaces 14 correspond to the four wedge-shaped surfaces 13. The abutment surfaces 14 below the trigger block 10 can slide against the wedge-shaped surfaces 13 at the top of the four trigger blocks 10 to prevent jamming between the trigger block 10 and the abutment block 11.
[0030] As a preferred technical solution of this embodiment, two limiting members 12 are fixedly installed on each of the plurality of abutting blocks 11. The two limiting members 12 are respectively sleeved on the abutting block 11 of the inner section and the abutting block 11 of the outer section of the sleeve shaft 4. The setting of the limiting members 12 can prevent the abutting blocks 11 from falling off the sleeve shaft 4.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
