A method for forming track shoes for tracked thin-shell vehicles

Abstract

The invention proposes a track shoe forming method for a track-type thin-shell vehicle, which includes designing a joint track shoe forging die: the joint track shoe forging die includes an upper die and a lower die, and the groove between the upper die and the lower die includes a pre-set The forging groove and the final forging groove, except for the flash groove, the structure of the final forging groove is the same as that of the pre-forging groove; Preforming is carried out in the pre-forging groove, so that the blank is filled with the pre-forging groove during pre-forging; the pre-forging is put into the final forging groove of the combined track shoe forging die, and the excess metal is filled into the flash groove. The invention produces a conjoined track shoe part from one forging, reduces the labor intensity of workers, saves working hours, effectively solves the problem of track fracture caused by tailor welding, improves the service life of the product, reduces welding, and minimizes the user's use and maintenance costs; The invention adopts the pre-forging groove and final forging groove structure of the conjoined track shoe forging die to realize a set of forging die and improve production efficiency.

Description

technical field [0001] The invention belongs to the technical field of forging, and in particular relates to a forming method of track shoes for track-type thin-shell vehicles. Background technique [0002] The track is an important and complex structural part of the walking part of the tracked armored combat vehicle, which plays a decisive role in the mobility and reliability of the vehicle. Track shoes are an important part of the track. The materials used are high-strength wear-resistant materials with high hardness (HB401~460). The demand for each vehicle is 196 pieces. The production base is very large, and the annual production volume is 200,000 pieces. above. At present, track shoes are mainly made of a forged part or welded separately to form a conjoined track shoe. However, the above two track shoes are prone to detachment during the test of the sports car, and the service life is low. Therefore, in order to solve the problem of track detachment of the mobile syst...
