Embodiment Construction

[0016] Such as figure 1 As shown, the bracket body 1 is formed by cold pressing of seamless steel pipe, the middle is designed as a bent pipe, the upper head has a constriction 3, the lower head has a narrowing 2, and there are many local flattened parts 4 on the pipe wall.

[0017] Such as Figure 1-6 As shown, the cold press forming process of the bracket body of the present invention comprises the following process steps: a. fixed-length blanking of seamless steel pipes (see figure 2 ); b. The diameter of the seamless steel pipe is reduced at one end (see image 3 ); c. Elbow (see Figure 4 ); d. One end of the seamless steel pipe shrinks (see Figure 5 ); e. In the forming mold, the wall of the seamless steel pipe is partially flattened (see figure 1 , Figure 6 ), the seamless steel pipe is filled with steel balls 11 when flattened and formed, and the two ends are movable to block, and the diameter of the steel balls 11 is 5mm.

[0018] Such as Figure 6 As shown,...

Abstract

The invention discloses a cold press molding process for a carrier body. The cold press molding process is characterized by comprising the following process steps of a, performing fixed-length blanking on a seamless steel tube; b, reducing the diameter of one end of the seamless steel tube; c, bending the tube; d, necking down one end of the seamless steel tube; and e, performing local flattening forming on the wall of the seamless steel tube in a forming mold, and filling the interior of the seamless steel tube with steel balls during flattening forming and blocking the two ends movably. According to the cold press molding process for the carrier body, the carrier body is subjected to cold press molding through the seamless steel tube, the process is simple, and the molded carrier body is high in strength, low in cost, high in size accuracy and attractive in appearance.

Description

technical field [0001] The invention relates to an automobile bracket used in an automobile chassis suspension system, in particular to a cold-press forming process of the automobile bracket body. Background technique [0002] The car bracket is used in the suspension system of the car chassis. The bracket body of the car bracket is a metal part. It is generally made by welding. The cost is high, the welding area is large, and the thermal deformation caused by welding is also large. Therefore, the installation size The precision is not high, the shape quality is poor, and the strength of the product is not high. If the bracket body is made by cold pressing of steel pipes, the technical problem is that in the final partial flattening of steel pipes, only fine sand can be filled into the inner cavity of the steel pipes. The fine sand has poor fluidity, and the steel pipes require partial The flattened deformation space is large, so the local flattened parts of the steel pipe ...
