Embodiment Construction
[0014] Referring to the accompanying drawings, the bending method of the connecting rod for the automobile chassis components includes the following steps:
[0015] a. Make bending tooling. The bending tooling includes upper and lower templates 1 and 10. The opposite surfaces of the upper and lower templates 1 and 10 are respectively fixed with mutually cooperating guide sleeves 2, guide pillars 3, and upper template 1. Punch 5 and die 9 are respectively installed between the lower template 10, and T-shaped chute 11 is respectively opened on both sides of the lower template 10, and a positioning block 7 is slidingly fitted in the T-shaped chute 11, and the inclined surface of the outer wall of the positioning block 7 Cooperate with an oblique extrusion block 6 fixed on the upper template, and a spring 8 is arranged between the inner side wall of the positioning block 7 and the outer side wall of the die;
[0016] b. Place the connecting rod 4 that needs to be shaped in the die...

The invention discloses a method for bending a connecting rod of an automobile chassis component. A bending tooling is manufactured; the bending tooling comprises an upper mold plate and a lower mold plate, guide sleeves and guide pillars matched with each other are respectively fixed on the opposite surfaces of the upper mold plate and the lower mold plate; a convex mold and a concave mold are respectively mounted between the upper mold plate and the lower mold plate, T-shaped sliding grooves are respectively formed in the two sides of the lower mold plate; positioning blocks are matched with the T-shaped sliding grooves in a sliding manner; the inclined planes of the outer side walls of the positioning blocks are matched with inclined squeezing blocks fixedly arranged on the upper mold plate; springs are arranged between the inner side walls of the positioning blocks and the outer side walls of the concave mold; and a shaping tooling does not require an operator to accurately load, so as to achieve shaping operation, greatly improve the production speed, and avoid production scrapping.
Description
technical field [0001] The invention relates to the field of molding of automobile chassis components, in particular to a bending method for connecting rods used in automobile chassis components. Background technique [0002] The connecting rods in the existing automobile chassis components are generally made by bending square tubes, but there are very strict requirements on the bending angle. [0003] Accurate, in order to meet the design requirements, it must be achieved through shaping, and the bending point of the connecting rod is not in the middle of the square tube, so the bending point of the connecting rod cannot be aligned with the bending point of the die, resulting in the failure of shaping. Contents of the invention [0004] The purpose of the present invention is to provide a method for bending connecting rods used in chassis components of automobiles. The shaping tool enables operators to perform shaping work without accurate loading, greatly improves pr...
