Description

Technical Field

[0001] This utility model relates to the field of metal material processing technology, specifically to a fixture for metal material processing. Background Technology

[0002] Metal processing is a technological process that transforms metal materials into items, parts, and components. It encompasses various techniques and methods, such as deformation processing, cutting, grinding, and welding. Deformation processing can be further divided into plastic forming, solid forming, and pressure processing. Plastic forming involves using a mold to plastically deform metal under stress at high temperatures; solid forming uses metal strips or sheets at room temperature for shaping; and pressure processing utilizes the plastic deformation of metal under external force to obtain parts of the desired shape and size. Cutting is a commonly used method for manufacturing parts with high requirements for dimensional, shape, and positional accuracy, as well as fine surface roughness. It uses cutting tools to cut metal blanks to obtain the desired part shape and size.

[0003] Furthermore, grinding is a processing method that uses abrasives to remove material, typically used in precision machining; while welding is a process for permanently joining metal materials, using heating or pressure to firmly connect them. When processing metal materials, fixtures are needed to hold and limit their movement. According to a metal material processing fixture with application number CN221696603U, rotating a rotating head causes a worm gear to rotate, which in turn drives a rotating shaft, which in turn rotates the metal material, thus facilitating its rotation and reducing workload. However, the inner wall of the slider is threaded with a bidirectional screw, which is rotatably engaged with the inner wall of the base plate. The bidirectional screw drives the support plate to move. During processing, such as cutting the metal material, metal chips are generated and fall into the base plate, affecting the movement of the support plate driven by the bidirectional screw, thus impacting the use of the fixture.

The top of the top seat 2 and above the first collection groove 4 and the second collection groove 11 are provided with an openable cleaning window. The surface of the shielding strip 7 can be cleaned by opening the cleaning window and then the cleaning window can be closed.

[0021] A collection box 1 is fixedly connected to the bottom of the top seat 2. Two first collection drawers 10 are placed inside the collection box 1. A second collection drawer 14 is placed inside the collection box 1 and between the two first collection drawers 10. One end of both the first collection drawer 10 and the second collection drawer 14 extends to the outside of the collection box 1. The first collection drawers 10 are both located below the first collection trough 4, and the second collection drawer 14 is located below the two second collection troughs 11. Metal scraps can be collected and stored through the two first collection drawers 10 and the second collection drawer 14.

[0022] Two first servo motors 15 are fixedly connected to one side of the top seat 2. The output ends of the first servo motors 15 are fixedly connected to one end of the first take-up roller 5.

[0025] Example 2

[0026] Please see Figures 1 to 3 This utility model provides a technical solution: one end of each of the two rotating shafts 18 extends to the outside of the fixed box 20 and is fixedly connected to a rotating disk 26. The rotating disk 26 has a first threaded groove 23 inside, and a screw 24 is threaded into the first threaded groove 23. A plurality of second threaded grooves 25 are opened on one side of the fixed box 20 and outside the rotating shaft 18. One end of each screw 24 extends into the second threaded groove 25 and is threaded into the second threaded groove 25. The other end of each screw 24 extends to the outside of the rotating disk 26. When it is necessary to remove the processed metal material, the mounting column 17 and the clamping block 19 can be driven to reset and move, thereby removing the metal material clamped between the two clamping blocks 19.

[0027] In summary, this metal processing fixture, when in use, places the material between two clamping blocks 19. Then, the output of the self-locking motor 27, driven by an external controller, rotates the ball screw 28. The ball screw 28 drives the drive block 13, which in turn moves the mounting post 17 and the clamping blocks 19, thus fixing the material in place. When the material's angle needs adjustment, one end of the screw 24 is unscrewed from the second threaded groove 25, releasing the restriction on the rotating shaft 18. Then, the output of the worm gear 21 drives the worm wheel 22, which in turn drives the rotating shaft 18 to drive the clamping blocks 19, thereby moving the material. The material rotates, and then one end of the screw 24 is screwed into the second threaded groove 25 to limit and fix the angle of the rotating disk 26, the rotating shaft 18, the clamping block 19, and the material. When the mounting column 17 moves, the output end of the first servo motor 15 drives the first winding roller 5 to rotate, so that the first winding roller 5 releases the outer shielding strip 7. At the same time, the output end of the second servo motor 16 drives the second winding roller 12 to rotate, so that the second winding roller 12 winds up the shielding strip 7. The scraper 8 scrapes the metal debris on the surface of the shielding strip 7 into the discharge trough 9, and then the metal debris falls into the discharge trough 9. The second collection drawer 14 collects and stores the metal material. After the metal material is processed, the output of the self-locking motor 27 drives the ball screw 28 to reset and rotate, causing the ball screw 28 to drive the drive block 13 to move the mounting column 17, rotating shaft 18 and clamping block 19 to reset and move, removing the processed metal material. At the same time, the output of the second servo motor 16 drives the second take-up roller 12 to reset and rotate, causing the shielding tape 7 wrapped around the outside of the second take-up roller 12 to be released. Simultaneously, the output of the first servo motor 15 drives the first take-up roller 5 to reset and rotate, causing the first take-up roller 5 to wind up the shielding tape 7, thereby driving the shielding tape 7 to move. Surface debris enters the first collection trough 4, and then the scraper 8 scrapes the metal debris on the surface of the shielding strip 7 into the discharge trough 9. The debris then falls into the first collection drawer 10 for storage. When it is necessary to clean the metal debris stored in the first collection drawer 10 and the second collection drawer 14, the first collection drawer 10 and the second collection drawer 14 are removed from the collection box 1, the metal debris stored in the first collection drawer 10 and the second collection drawer 14 are poured out, and then the first collection drawer 10 and the second collection drawer 14 are pushed back into the collection box 1 for metal debris collection and storage.

[0028] 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.
