Tooling for tire die forging to manufacture gear blanks

Abstract

The invention relates to a tooling for tire die forging to manufacture gear blanks, which comprises a cylindrical lower die, a cylindrical upper die and an outer casing. The lower end surface of the lower die is flat, and the upper end face of the lower die is provided with a A large ring-shaped boss matching the upper end surface, the large ring-shaped boss is stepped; the upper end surface of the upper mold is a plane, and the lower end surface of the upper mold is provided with a small annular boss that matches the lower end surface of the gear; The overcoat is a ring column, and the inner diameter of the overcoat matches the diameters of the lower die and the upper die. The invention is suitable for manufacturing gear blanks. Compared with the currently used die forging hammers, the tooling used for tire die forging to manufacture gear blanks can produce not only small gear blanks but also large gear blanks without increasing production costs and ensuring The filling of the gear blank is complete.

Description

technical field [0001] The invention relates to a tooling for manufacturing gear blanks, in particular to a tooling for manufacturing gear blanks by tire die forging. Background technique [0002] With the continuous development of industry, gears are widely used in various industries. The structure of gear 1 is as follows figure 1 As shown, the center of the gear 1 is provided with an inner hole 11, the upper end surface of the gear 1 is provided with a large annular groove 12 concentric with the inner hole 11, the bottom surface of the large annular groove 12 is stepped, and the lower end surface of the gear 1 A small annular groove 13 concentric with the inner hole 11 is provided. [0003] At present, die forging hammer is mostly used to manufacture gear blanks, but due to the limitation of die forging hammer size and supporting equipment, it can only manufacture small gear blanks. To manufacture large gear blanks, it is necessary to enlarge the size of die forging hamm...

Problems solved by technology

[0003] At present, die forging hammer is mostly used to manufacture gear blanks, but due to the limitation of die forging hammer size and supporting equipment, it can only manufacture small gear blanks. To manufacture large gear blanks, it is necessary to enlarge the size of die forging hammer and replace supporting equipment. Production The cost is obviously increased, and the expansion of the size of the die forging hammer will lead to incomplete filling of the gear blank during manufacture
