Problems solved by technology

The existing free forging method is according to figure 2 Forming or forging into the shape of a flat round cake. Because the rim and the spokes of this forming method are machined in the later stage, the fiber direction of the hub is as follows: image 3 As shown in areas A and B in the middle, the fiber structure on both sides is inconsistent. The existing production method is made into a flat round cake shape and then cut. The remaining block of the process is large and the weight of the blank is medium, which makes the production cost high.

Embodiment Construction

[0017] A kind of processing method of speed ratio wheel, see figure 1 : Loading and unloading from the raw material, then upsetting the obtained blank, and then elongating to obtain the corresponding blank, then placing the blank in the corresponding forging tooling for forging pre-forming, the formed blank has a double-boss structure, and then passed The tool trims and shapes the speed ratio wheel of the corresponding model.

[0018] When the tool is trimmed, the corresponding side of the single-side tooling is trimmed, and the double-boss structure is turned over after the one-side trimming, and the other side is trimmed through the single-side tooling to obtain the corresponding model of the speed ratio wheel after the double-sided trimming is completed;

[0019] The size of the inner hole of the forging tool is equal to the size of the hub of the product, and the size of the blank can be put into the inner hole of the forging tool, and then the forging tool forges the bla...

Abstract

The invention provides a method for machining speed ratio wheels. The shape of workblanks obtained after forging is close to that of a finished product, all fiber forging is realized, the left processblocks are reduced, and the weight of the workblanks is reduced. Raw materials are blanked, then the obtained discharged materials are upset, drawing out is carried out to obtain corresponding workblanks, the workblanks are placed in corresponding forging tools for forging preforming, the formed workblanks are of dual-boss structures, and corresponding models of the speed ratio wheels are formedby tool finishing.

Description

technical field [0001] The invention relates to the technical field of material heat treatment, in particular to a processing method of a speed ratio wheel. Background technique [0002] Existing molding technology is based on experience and experimental data. To formulate a new part molding process often requires a lot of modification and debugging during production. The development of computer and computing technology, especially the development of computing technology for nonlinear problems, has made the simulation analysis and optimization of the forming process possible. Many commercial software such as casting, forging, panel stamping, and mold CAD / CAM have been formed through a lot of work abroad. It has effectively promoted the development of near-net shaping technology. Our country has done a lot of work in simulation analysis and research, but the forces are scattered, the investment of each unit is insufficient, there are many individual studies, and few of them h...
