Description

Technical Field

[0001] This invention relates to the field of cold stamping technology, and in particular to a processing technology for a shock absorber tripod. Background Technology

[0002] The shock absorber bracket is an important component of automotive shock absorbers, widely used in automobiles. For example... Figure 1 and Figure 2 As shown, the shock absorber bracket on a new energy vehicle has a relatively complex structural design. It includes a bracket body 1 with a certain curvature, and a recess 2 for mounting inserts is provided in the central area of ​​the bracket body 1. Threaded fixing holes 3 are provided on the three corners of the bracket body 1.

[0003] The traditional manufacturing process for this type of shock absorber tripod involves first bending the tripod into shape, and then welding nuts onto it. This process has drawbacks such as significant material waste, low production efficiency, heavy finished product weight, and high processing costs. Therefore, the traditional manufacturing process cannot meet current product forming requirements and needs further optimization. Summary of the Invention

[0004] Based on the above problems, the purpose of this invention is to provide a processing technology for shock absorber tripods, which ensures the forming accuracy of shock absorber tripods and improves material utilization and production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A process for manufacturing a shock absorber tripod includes the following steps:

[0007] Material is fed in and punched out as a round triangular piece;

[0008] A positioning hole is punched in the center of the round triangular piece of material in one punching operation;

[0009] Stretching: drawing the central area of ​​the triangular piece of material to create a bulge;

[0010] Shaping involves reshaping protrusions to obtain cavities of the desired shape;

[0011] Trim the edges of the round triangular piece to obtain the tripod body of the target shape;

[0012] Convex punching: stamping convex bulges on the three corners of the tripod body;

[0013] Secondary punching to pierce through the convex bulge;

[0014] Flipping the hole involves turning the hole wall of the convex hull outward to form a fixed hole wall;

[0015] Bending and shaping: bending the tripod body into the target curvature;

[0016] Break through the protruding end face by punching the bottom.

[0017] Tapping involves machining internal threads into the wall of a fixed hole to obtain a threaded fixed hole.

[0018] Optionally, during the stretching step, the circular triangular sheet is stretched in stages, with at least two stretching operations performed.

[0019] Optionally, during the shaping step, the raised sidewalls are perpendicular to the round triangular piece.

[0020] Optionally, in the edge trimming step, the right-angled edge formed by the cutting is tangent to the rounded corner of the rounded triangular piece.

[0021] Optionally, during the bending forming step, the tripod body is formed into a spherical shape, and the shape of the cavity is not affected.

[0022] Optionally, the positioning holes can be removed during the bottom punching step.

[0023] In summary, compared with existing technologies, this shock absorber tripod processing technology realizes a series of processes such as blanking, primary punching, stretching, shaping, edge trimming, embossing, secondary punching, flanging, bending and forming, bottom punching, and thread tapping, thereby forming shock absorber tripod products with good consistency and balance, ensuring the accuracy of shock absorber tripods, improving material utilization and production efficiency, and producing lightweight products with a high pass rate.

[0051] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] This preferred embodiment provides a processing technology for a shock absorber tripod, specifically addressing... Figure 1 and Figure 2 The shock absorber tripod shown has an optimized process to solve the problems of material waste, low production efficiency, and heavy product weight in traditional manufacturing processes, thus ensuring molding quality.

[0053] Specifically, such as Figure 3 As shown, the manufacturing process of this shock absorber tripod includes the following steps:

[0054] Step S010, Blanking: Punch out a round triangular piece 4 from a piece of hot-rolled steel sheet for automotive structures according to the dimensions of the shock absorber bracket. See details. Figure 4 and Figure 5 .

[0055] Step S020, First punching: Punch a positioning hole 5 in the center of the round triangular piece 4 to position and clamp the round triangular piece 4. See details. Figure 6 and Figure 7 .

[0056] Step S030, stretching: stretch the central area of ​​the round triangular piece 4 to form a protrusion 6.

[0057] Specifically, in this stretching step, to avoid overstretching or understretching, the round triangular sheet is stretched in four steps, with at least two stretching operations to ensure stretching quality. This embodiment takes one stretching operation followed by two stretching operations as an example. See details below. Figures 8 to 11 .

[0058] Step S040, Shaping: Shaping the protrusion 6 to obtain the cavity 2 of the target shape, see details. Figures 12 to 13 .

[0059] According to the usage requirements, the cavity 2 here needs to be fitted with inserts. In order to prevent the inserts from falling out and to ensure proper assembly, the shape of the cavity 2 is very important. The sidewall of the protrusion 6 should be perpendicular to the round triangular piece 4. High forming quality can be obtained through step stretching and shaping.

[0060] Step S050, Edge Trimming: Trim the edges of the circular triangular piece 4 to obtain the target shape of the tripod body 1. See details. Figures 14 to 15 .

[0061] Specifically, in this edge-cutting step, the right-angled edge formed by the cutting is tangent to the rounded corner of the rounded triangular piece 4, thus achieving the target molding shape.

[0062] Step S060, Embossing: Embossing 7 is punched onto the three corners of the tripod body 1. See details. Figures 16 to 17 .

[0063] The embossing process here can effectively position the threaded fixing hole 3 and prevent the threaded fixing hole 3 from cracking during the subsequent forming process.

[0064] Step S070, Secondary punching: Punch through the convex bulge 7, see details. Figures 18 to 19 .

[0065] Step S080, Flanging: Flanging the hole wall of the convex bulge 7 to form the fixed hole wall 8, see details. Figures 20 to 21 .

[0066] Step S090, Bending and Shaping: Bend the tripod body 1 into the target curvature, see details. Figures 22 to 23 .

[0067] The tripod body 1 here is shaped into a spherical shape as needed, and the shape of the cavity 2 is not affected during the bending process.

[0068] Step S100, Bottom Punching: Punch through the end face of protrusion 6, see details. Figures 24 to 25 .

[0069] It should be noted that when punching the bottom, the positioning hole 5 should be removed as well.

[0070] Step S110, Tapping: Machining internal threads on the wall of the fixed hole 8 to obtain the threaded fixed hole 3, ultimately obtaining... Figure 1 and Figure 2 The shock absorber tripod product shown.

[0071] Therefore, the processing technology of this shock absorber tripod realizes a series of processes such as blanking, primary punching, stretching, shaping, edge trimming, embossing, secondary punching, flanging, bending and forming, bottom punching, and thread tapping, thereby forming a shock absorber tripod product with good consistency and balance, ensuring the accuracy of the shock absorber tripod, improving material utilization and production efficiency, and the product is lightweight and has a high pass rate.

[0072] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
