Description

Technical Field

[0001] This utility model relates to the field of aluminum bracket processing technology, specifically a universal cutting mold for aluminum brackets. Background Technology

[0002] In the production process of automotive aluminum anti-collision beams, aluminum brackets are key components used to install automotive functional parts. Their processing technology typically includes steps such as extrusion, sawing, and stamping. Among these, sawing is a common cutting method used to divide extruded aluminum profiles into bracket parts of the required length. In existing technologies, sawing operations rely on rotating saw blades to separate profiles through mechanical cutting. This sawing process is widely used in industrial production because it is relatively simple to operate and easy to integrate into production lines. However, this process involves using saw blades with a specific thickness, which causes material to be removed during the cutting process, thereby reducing the effective utilization rate of raw materials. At the same time, the sawing process generates a large amount of metal chips, which may adhere to the surface of the parts or mix into the working area, not only increasing the complexity of subsequent processing, but also potentially affecting the final quality of the parts. To address this, we propose a universal cutting die for aluminum brackets. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a universal cutting mold for aluminum brackets, which can avoid waste of raw materials and avoid the generation of debris during processing, and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a universal cutting mold for aluminum brackets, including a lower mold base. Two corresponding mold feet are fixed to the left and right ends of the upper side of the lower mold base by bolts. An mounting plate is fixed to the upper side of the two mold feet by bolts. A reset assembly is installed between the mounting plate and the lower mold base. Two corresponding limiting brackets are fixed to the upper side of the mounting plate. A guide hole is provided in the middle of the front limiting bracket, and a flow guide hole is provided in the middle of the rear limiting bracket. A stationary cutting blade fixing seat is fixed to the front end of the two limiting brackets, and a stationary cutting blade is fixed inside the stationary cutting blade fixing seat. A movable cutting blade fixing seat is slidably connected to the rear end of the two limiting brackets. The movable cutting blade fixing seat is fixed to the upper side of the reset assembly, and a movable cutting blade is fixed inside the movable cutting blade fixing seat. The movable cutting blade and the stationary cutting blade are in contact. A cutting groove is provided in the middle of both the movable and stationary cutting blades. An aluminum bracket body is installed inside the two cutting grooves. The modular design allows for quick replacement of the movable and stationary cutting blades according to different aluminum bracket products during use.

[0005] Furthermore, the reset assembly includes a spring limiting block, a nitrogen spring, and a nitrogen spring fixing seat. The nitrogen spring fixing seat is fixed to the mounting plate and the lower mold base by bolts. Three corresponding nitrogen springs are installed inside the nitrogen spring fixing seat. The upper end of the three nitrogen springs is fixed with a spring limiting block. A strip-shaped opening is opened on the upper side of the mounting plate. The spring limiting block is slidably connected inside the strip-shaped opening. The spring limiting block is fixed to the lower side of the moving cutter fixing seat by bolts. By setting the reset assembly, it can be ensured that the moving cutter automatically resets after the cutting action.

[0006] Furthermore, a positioning block fixing seat is fixed to the rear side of the moving cutter fixing seat, and a set screw fixing seat is fixed to the rear end of the lower side of the positioning block fixing seat. A threaded hole is provided on the lower side of the set screw fixing seat, and an adjusting set screw is threaded inside the threaded hole. A positioning block is rotatably connected to the front end of the adjusting set screw. By setting the positioning block, the cutting length can be limited.

[0007] Furthermore, two corresponding limiting holes are provided on the left and right sides of the positioning block. The positioning block guide post is slidably connected inside the limiting hole. Both positioning block guide posts are fixed to the front side of the set screw fixing seat. The positioning block is limited by setting the positioning block guide posts.

[0008] Furthermore, two corresponding mounting blocks are fixed on the left and right sides of the moving cutter fixing seat. Both mounting blocks are slidably connected between the two limiting brackets. The upper side of the mounting plate is provided with a groove corresponding to the mounting blocks. By setting the mounting blocks, the stability of the vertical movement of the moving cutter fixing seat can be ensured.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This universal cutting mold for aluminum brackets has the following advantages: 1. By adopting a staggered shearing mechanism of moving and stationary cutting blades, the traditional sawing process is replaced. This design avoids material loss caused by the thickness of the saw blade, thereby greatly improving the material utilization rate of aluminum bracket parts and effectively reducing production costs. The entire cutting process, under the synergistic effect of the limiting bracket and the reset component, ensures the precise separation of the aluminum bracket body without the need for additional material removal, demonstrating the industrial advantage of resource conservation. 2. Because the shearing action of the moving and stationary cutting blades acts directly on the aluminum bracket body, it does not produce chips or metal dust like traditional sawing. This not only reduces the necessity of subsequent cleaning processes, but also avoids the impact of chip adhesion on the quality of parts. 3. With replaceable moving and stationary cutting blade assemblies, along with positioning block fixing seats and adjusting set screws, it can quickly adapt to the processing requirements of different aluminum bracket products without replacing the entire tooling. This design not only reduces tooling development costs but also improves the adaptability and maintenance convenience of the production line. Attached Figure Description

The modular design allows for quick replacement of the movable cutting blade 106 and the stationary cutting blade 112 according to different aluminum bracket products. The cutting edges of both the movable cutting blade 106 and the stationary cutting blade 112 are designed with chamfering to prevent the aluminum profile from bending and jamming.

[0014] Furthermore, the reset assembly includes a spring limiting block 107, a nitrogen spring 108, and a nitrogen spring fixing seat 109. The nitrogen spring fixing seat 109 is fixed between the mounting plate 103 and the lower mold base 101 by bolts. Three corresponding nitrogen springs 108 are installed inside the nitrogen spring fixing seat 109. The upper end of the three nitrogen springs 108 is fixed with a spring limiting block 107. A strip-shaped opening is opened on the upper side of the mounting plate 103. The spring limiting block 107 is slidably connected inside the strip-shaped opening. The spring limiting block 107 is fixed to the lower side of the moving cutter fixing seat 105 by bolts. By setting the reset assembly, it can be ensured that the moving cutter automatically resets after the cutting action.

[0015] Furthermore, a positioning block fixing seat 115 is fixed to the rear side of the moving cutter fixing seat 105, and a set screw fixing seat 114 is fixed to the rear end of the lower side of the positioning block fixing seat 115. A threaded hole is provided on the lower side edge of the set screw fixing seat 114, and an adjusting set screw 113 is threadedly connected inside the threaded hole. A positioning block 117 is rotatably connected to the front end of the adjusting set screw 113. By setting the positioning block 117, the cutting length can be limited.

By setting the mounting block slider 104, the stability of the vertical movement of the moving cutter fixing seat 105 can be ensured.

[0018] The working principle of the universal cutting mold for aluminum brackets provided by this utility model is as follows: During use, the lower mold base 101 is fixed on the lower table of the stamping machine, with the mold feet 102 and mounting plate 103 providing a support structure. After fixing, the stamping machine is adjusted so that the moving cutter fixing seat 105 is in contact with the stamping machine's pressure block. Then, the position of the positioning block 117 is precisely adjusted by rotating the adjusting screw 113. The positioning block 117 is guided by the positioning block guide post 116 to ensure stability. At this time, the aluminum bracket body 110 is inserted through the guide hole 119 of the limiting bracket 118, so that its rear end contacts the positioning block 117 for accurate positioning. After starting the stamping machine, the stamping machine's pressure block moves downwards. The moving cutter holder 105 moves downward. During the movement, the holder slider 104 slides between the limiting brackets 118 to ensure vertical stability. The moving cutter 106 moves downward and forms a misaligned shear with the stationary cutter 112, thereby cutting the aluminum bracket body 110. After cutting, the part slides down through the guide hole 120 to avoid residue. At the same time, the spring limiting block 107 automatically pushes the moving cutter holder 105 to reset under the action of three nitrogen springs 108. After completion, the profile material is pushed to repeat the above process to achieve continuous and efficient cutting. The entire design is modular. When changing products, only the moving cutter 106 and the stationary cutter 112 need to be replaced to adapt to different aluminum brackets.
