Abstract

The invention discloses a wheel inversion press fit mold. The wheel inversion press fit mold comprises an upper mold frame, a lower mold base, a spoke and a rim; the lower mold base comprises a lowermold plate, multiple guide columns, springs arranged on the guide columns in a sleeving manner, a movable plate penetrating the guide columns and fixed to the springs, and a spoke fixing assembly; a positioning disc and a positioning pin are arranged on the top of the spoke fixing assembly, the outer diameter of the spoke positioning disc is the same with the diameter of a spoke middle hole, the movable plate is provided with an elastic pin and a pointer, the upper mold frame comprises an upper mold plate, a rim positioning ring fixed above the upper mold plate and a rim positioning assembly,the spoke is fixed above the spoke fixing assembly through a positioning disc and a positioning pin, a valve hole is formed in the side edge of the rim, the rim is fixed to the movable plate through the elastic pin, and is positioned through matching of the pointer and the valve hole, the problems that when a traditional mold is used for producing wheels, discharging is difficult, precision is notenough, and alignment of the valve hole and a spoke air hole is difficult are solved, the beneficial effects of being labor-saving in discharging, and high in positioning precision are achieved, andproduction efficiency is effectively improved.

Description

technical field

[0001] The invention relates to the technical field of wheel assembly tooling manufacturing, in particular to a wheel press-fitting die used for the combination of wheel spokes and rims. Background technique

[0002] The wheel is a rotating component that bears load between the tire and the axle, and is mainly composed of a rim, a spoke and a hub. The rim is a part of the wheel where the tire is fixed, and the spoke is a supporting part between the axle and the rim. The hub is the connection The rotating assembly of the wheel and axle responsible for bearing the load between the tire and the axle is first assembled by pressing the spokes into the rim using a wheel press-fit tool mounted on the press table.

[0003] The currently used wheel press-fitting molds are usually of a formal structure, that is, the rim is mounted on the lower mold base, and the spokes are pressed into the rim from top to bottom to complete the press-fitting of the wheel. When using th...
