り、加工サイクルが長くなり、コスト増となる。When a bracket is manufactured by sand mold casting, the number of cutting processes is increased, the processing cycle is long, the cost is increased, and the brittleness is large. Also, when manufacturing by the aluminum die-cast manufacturing method, air is mixed into the material, causing a sink mark,
The reliability was low, and the squeeze die casting method had high reliability, but the brittleness was greater than that of the wrought material. Although extruded extruded products are less brittle, they have less freedom in design, and therefore ribs and attachments must be welded to the cylinder to achieve even higher rigidity. It was necessary to increase the wall thickness. If the wall thickness is increased, a large amount of material is required, and there is a drawback that the weight cannot be reduced. Further, in the forging process, forging from a raw material such as a round bar or a square bar also requires the process of forming a hole for press-fitting an anti-vibration rubber, resulting in a longer machining cycle and an increase in cost.

A bush mounting bracket is formed by the rib 3 for reinforcing the tubular portion 1 and the mounting portion 2. A mounting hole 4 is formed in the mounting portion 2. Cylinder part 1 and mounting part 2 shown in FIG.
As shown in FIG. 2, a wrought material is extruded and molded, and cut into a predetermined length. The width L (see FIG. 3) of the tubular portion 1 and the mounting portion 2 in the extruded state of the wrought material is shown in FIG.
It is wider than the width 1 (see FIG. 6) of the rib 3 shown in FIG. After extruding the wrought material as shown in FIG. 3, the wrought material is cut and then forged to form the rib 3 as shown in FIG. The inner diameter D of the tubular portion 1 in FIG. 3 is approximately the same as the inner diameter d of the tubular portion 1 after the rib 3 is formed. FIG. 5 is an end view taken along the line AA in FIG. 4, and shows a width l after the rib 3 is formed by forging rather than the width L at the time of extrusion molding.
Is narrower. FIG. 6 is an end view taken along line BB in FIG. 4, and the width of the tubular portion 1 is also narrower than that during extrusion molding.

付用ブラケットを提供することができる。As described above, according to the present invention, the tubular portion and the mounting portion are extruded with the wrought material, and the tubular portion and the mounting portion molded with the wrought material are forged. Since the rib is formed, the brittleness is small, the cost is not high, and the manufacturing is easy. Although ribs cannot be obtained by extrusion molding of wrought material, they can be easily formed by forging, and the rigidity is higher than that of extrusion molded by performing forging, and the wall thickness is increased. There is no need to give rigidity. Overall, according to the present invention, it is possible to provide a highly reliable bush mounting bracket.
