A compound structure track shoe and its forming method

Abstract

The invention belongs to the field of forming of track shoes, particularly relating to a composite-structure track shoe and a forming method thereof. The composite-structure track shoe is characterized in that an inducing tooth wear-resistant insert (2) is inlaid in an inducing tooth part of the upper part of a track shoe body (1); a grouser wear-resistant insert (3) is inlaid in a landing grouser part of the lower part of the track shoe body; a pin hole reinforcing insert (4) is inlaid in a pin hole part in the middle of the track shoe body; and the lightweight high-strength and high-wear-resistance composite-structure track shoe is prepared by a rheological extrusion casting and inlaying forming method. The composite-structure track shoe is light in weight, an aluminum alloy body is high in structural strength, the strength of the composite-structure track shoe is close to that of a forged aluminum alloy track shoe, requirements on the strength of a tracked vehicle are met, and by a casting and inlaying structure, the problem that the aluminum alloy track shoe is poor in local wear resistance and low in performance is solved. By the forming method, near net shaping of a complicated structure of the composite-structure track shoe can be realized. The composite-structure track shoe has the advantages of convenience in operation, high machining efficiency, long service life of a mold, few followed-up machining and high material utilization.

Description

technical field [0001] The invention belongs to the field of track shoe manufacturing, in particular to a track shoe with a composite structure and a forming method thereof. Background technique [0002] Track shoes are an important part of the walking part of tracked vehicles. At present, the track shoes widely used are mainly steel track shoes made by casting, forging or welding. Cast track shoes have low structural strength and reliability, which limits their application range. The track shoes produced by forging and welding process have high performance and slightly reduced weight, but the production efficiency is low, and the near-net shape cannot be realized. The follow-up machining is large, which makes the material utilization rate low and the manufacturing cost is high. [0003] The overall weight of the steel track is relatively large, which consumes a considerable output power of the tracked vehicle and affects the mobility of the vehicle. Lightweight is an inher...

AI Technical Summary

Problems solved by technology

However, the hardness and wear resistance of aluminum alloy are relatively low, and the induced teeth of aluminum alloy track shoes and the spur part in contact with the ground cannot meet the wear resistance requirements of the complex terrain walking process.
