[0015] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.

[0016] The idea of ​​the processing method of the present invention is to use a pressure on the edge pressing tool to complete the edge pressing process of the component product, which is used to replace the original process of using a lathe to roll the edge.

[0017] The edge pressing method of this embodiment uses an edge pressing device on the baffle component products, uses a pressure device to act on the edge pressing tool, applies a force perpendicular to its end face to the edge pressing tool, and completes the edge pressing process after stamping. The process method is simple to operate, does not require clamping and alignment, and can be completed by clamping from component installation to edge pressing, reducing the flow between processes. Compared with the original process method, the production efficiency is increased by more than 50%. Up to now, the edge pressing qualified rate of this process method has reached 100%. The advantages of this simple process method can be more demonstrated in mass production.

[0018] The outer shape of the edge pressing tool is a variable diameter cylinder, and the outer diameter of the lower end cylinder is greater than the outer diameter of the upper end cylinder.

[0019] A variable diameter cylindrical chamber is provided in the inner cavity at the lower end of the edge pressing tooling, and the size of the chamber matches the size of the baffle component products.

[0020] Use suitable materials to make edge pressing tools, and avoid damage to the product appearance under the premise of meeting the strength requirements. Use the circumference and depth positioning of the baffle to process the internal dimensions and chamfers of the tooling, and require that its internal shape does not affect the product size and appearance. Figure 3 This is a design drawing of a baffle assembly edge pressing tooling. The tooling design dimensions can be appropriately adjusted according to the different sizes of the baffle assemblies to form a series of tooling for edge pressing of baffle assembly products, thereby promoting the application of this process method in production to the greatest extent.

[0021] During the edge pressing process, press the edge pressing tooling and baffle assembly Figure 4 Place the edge pressing tool in the middle position, place the edge pressing tool above the baffle assembly product, and apply a force F perpendicular to its end face to the edge pressing tool above the edge pressing tool to make the inner cavity R1 rounded corner position (see Figure 3), the thin edge of the baffle assembly is squeezed, so as to achieve the purpose of deforming the circumference of the thin edge of the baffle assembly, and finally ensure that the internal parts of the baffle assembly cannot move, so as to meet the use requirements.

[0022] During operation, use the two inner hole circumference sizes of φ22.2 (0~+0.3) and φ19.7 (0~+0.1) (see Figure 3 ) Position and align the baffle assembly to prevent uneven circumferential force and avoid component edge distortion and cracking. The vertical direction depends on the inner hole depth 3, 4.5 (see Figure 3 ) to control the degree of edge bending.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
