Description

Technical Field

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

[0002] Metallic materials refer to the general term for materials with metallic properties, which are composed mainly of metallic elements. Metallic material processing includes two types: hot working and cold working. Hot working involves heating the metal and then applying techniques such as extrusion, stretching, and melting. Cold working involves directly processing the metal by turning, cutting, planing, milling, bending, stamping, drilling, grinding, etc.

[0003] In the process of metal processing, it is often necessary to use fixtures to maintain the stability of the metal materials. Existing fixtures clamp metal materials from both sides, but when processing certain metal materials, such as cutting or drilling metal sheets, it is necessary to support the bottom of the metal sheet to ensure it remains horizontal. Such fixtures can only clamp the metal material from the side, which is insufficient for some application scenarios. Therefore, an improved metal processing fixture is proposed. Utility Model Content

[0034] The working principle of the utility model is as follows:

[0035] S1. Place the metal material inside the clamping plate 4, rotate the first double-acting screw 2, the first double-acting screw 2 drives the two support plates 3 to move towards each other, so that the two clamping plates 4 clamp the metal material. Then, rotate the rotating rod 5 to drive the pressure plate 6 to move down, so that the pressure plate 6 cooperates with the clamping plate 4 to clamp the metal material.

[0036] S2. When it is necessary to support the bottom of the metal material, the second bidirectional lead screw 9 is rotated according to the processing requirements, and the two sliders 10 move towards or away from each other in sync, which drives the drive frame 11 to move synchronously.

[0037] S3. Under the constraint of the constraint frame 7, the movable support rod 12 moves horizontally along the direction of the constraint frame 7, causing the movable top rod 13 to move horizontally. This allows the movable top rod 13 to move horizontally, supporting the metal material at the required position and ensuring that the metal material is in a horizontal state.

[0038] Compared with the prior art, the present invention has the following advantages:

[0039] 1. This metal material processing fixture, through the arrangement of a constraint frame 7, a vertical plate 8, a second bidirectional lead screw 9, sliders 10, a drive frame 11, a movable support rod 12, and a movable top rod 13, allows for support of the metal material's bottom when necessary. The second bidirectional lead screw 9 is rotated according to processing requirements, causing the two sliders 10 to move synchronously towards or away from each other. This synchronously drives the drive frame 11 to move. Under the constraint of the constraint frame 7, the movable support rod 12 moves horizontally along the direction of the constraint frame 7, causing the movable top rod 13 to move horizontally. This horizontal displacement of the movable top rod 13 ensures that it supports the metal material at the required position, guaranteeing the metal material is horizontal. The fixture can support the metal material as needed, and the support position can be freely adjusted, greatly improving the fixture's applicability.

[0040] 2. This metal material processing fixture has a guide rod installed inside the vertical plate 8. The slider 10 is sleeved on the guide rod, which guides and constrains the slider 10, making its movement more stable. A fixed support rod 14 is installed at the center of the base 1, and a fixed top rod 15 is threadedly connected to the top of the fixed support rod 14. The fixed top rod 15 supports the center of the metal material. A movable top rod 13 is threadedly connected to the movable support rod 12, and the extension length of the movable top rod 13 can be adjusted by rotation. Similarly, the extension length of the fixed top rod 15 can also be adjusted as needed.
