Description

Technical Field

[0001] This utility model relates to the field of shaping tooling technology, and in particular to a workpiece extrusion shaping tooling. Background Technology

[0002] The chassis integrates multiple key functional components. The structural design, dimensional tolerance control, and assembly precision of these precision parts directly affect the overall performance of the equipment. Specifically, these factors are significantly reflected in core performance indicators such as the airflow efficiency of the cooling system, the compatibility of electromagnetic shielding, the operability of daily maintenance, and the load-bearing strength of the overall mechanical structure of the chassis.

[0003] To ensure a perfect geometric fit between each functional component and its specific mounting position within the chassis, while also meeting ergonomic design requirements so that operators can efficiently and comfortably complete assembly and maintenance tasks, high-precision extrusion forming fixtures must be used to precisely shape these metal parts. These fixtures require strict dimensional tolerance control capabilities and must ensure the uniformity and stability of material flow during processing.

[0004] However, traditional extrusion shaping fixtures have many bottlenecks that restrict efficiency due to their complex structural design: on the one hand, the positioning and placement of workpieces before processing is cumbersome and time-consuming; on the other hand, the removal of workpieces after processing is also difficult. These factors not only increase the labor intensity of operators, but also lead to low efficiency of the entire processing flow, becoming key factors restricting the improvement of production efficiency. Therefore, optimizing and improving the existing fixture structure and simplifying the operation process has become an urgent need to improve processing efficiency. Utility Model Content

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example

[0029] Reference Figures 1 to 3 This embodiment of the present invention provides a workpiece extrusion and shaping fixture, including a processing table 100, a support member 200 and an extrusion positioning member 300 disposed on the processing table 100. The support member 200 has recesses 201 on both sides for accommodating workpieces 400, and protrusions 202 for connecting and limiting workpieces 400 are provided in the recesses 201. The extrusion positioning member 300 has a first extrusion cylinder 301 and a second extrusion cylinder 302 disposed on two adjacent sides of the workpiece 400. Through the dual-cylinder collaborative design of the first extrusion cylinder 301 and the second extrusion cylinder 302, these two hydraulic cylinders are respectively arranged on the two adjacent sides of the workpiece 400, forming a multi-directional force application layout. In the actual processing, the operator first accurately places the workpiece 400 to be processed into the recess 201. At this time, the protrusion 202 will form a preliminary contact positioning with the workpiece 400. When the extrusion positioning component 300 is activated, the first extrusion cylinder 301 and the second extrusion cylinder 302 will simultaneously apply precise and controllable extrusion force, causing the workpiece 400 to undergo plastic deformation in multiple directions.

[0030] In this way, on the one hand, the pre-positioning of the protrusion 202 inside the notch 201 and the subsequent extrusion deformation work together to ensure that the final geometric shape of the workpiece 400 is highly consistent with the design size, which significantly improves the processing accuracy; on the other hand, this structural design optimizes the human-machine interaction experience, and operators can quickly and accurately put the workpiece 400 into or take it out of the notch 201, which greatly improves production efficiency.

[0031] The top of the notch 201 extends from the top of the support member 200, and the protrusion 202 is located at the bottom of the notch 201. The protrusion 202 is located at the bottom of the notch 201 and plays an initial positioning and support role when the workpiece 400 is placed in. Due to the open top of the notch 201, the operator can more intuitively align the workpiece 400 with the notch 201 when placing it, reducing positioning deviations caused by obstructed vision or insufficient operating space. At the same time, the removal of the workpiece 400 after processing is also smoother. The operator can easily grasp or use tools to remove it from the notch 201 without worrying about interference with other structures of the support member 200.

[0032] The workpiece 400 has a groove 401 that engages with the protrusion 202. As the groove 401 engages with the protrusion 202, one side wall of the workpiece 400 comes into contact with the side wall of the groove 401. When the workpiece 400 is placed in the groove 201, the groove 401 and the protrusion 202 form a tight engagement, enabling the workpiece 400 to be precisely positioned in the horizontal direction. At the same time, the contact surfaces of the side wall of the groove 401 and the protrusion 202 abut against each other, further restricting the displacement freedom of the workpiece 400 and effectively preventing it from shifting or shaking during subsequent processing.

[0033] The notch width of 201 is adapted to the workpiece width of 400.

[0034] The first extrusion cylinder 301 is installed inside the recess 201, and its output end corresponds to the side wall of the workpiece 400 placed in the groove 401. After the workpiece 400 completes its initial positioning through the insertion of the groove 401 and the protrusion 202, the first extrusion cylinder 301 is activated according to preset parameters, and its output end is pushed towards the side wall of the workpiece 400 at a controllable speed. At the moment of contact, the extrusion force causes the material of the workpiece 400 to undergo plastic flow, and the final formed contour perfectly matches the geometry of the inner cavity of the recess 201 and the protrusion 202.

[0035] The output end of the second extrusion cylinder 302 faces the workpiece 400 placed in the recess 201. During processing, the second extrusion cylinder 302 starts before the first extrusion cylinder 301, applying a preset holding pressure to the front of the workpiece 400. When the first extrusion cylinder 301 begins lateral extrusion, the pressure value of the second extrusion cylinder 302 is dynamically adjusted according to system feedback, ensuring that the workpiece 400 maintains stable front geometry while achieving lateral forming. This synergistic effect of timing control and force adjustment keeps the workpiece 400 under control throughout the complex plastic deformation process.

[0036] After the groove 401 and the protrusion 202 are inserted, there is a margin 500 between the bottom of the workpiece 400 and the bottom of the groove 201. The margin 500 provides the necessary material flow space for the workpiece 400 during the extrusion molding process, allowing the workpiece to produce reasonable elastic deformation within a controlled range and avoiding stress concentration caused by rigid constraints.
