Forming method of track shoe for tracked thin-shell vehicle

Abstract

The invention provides a forming method of a track shoe for a tracked thin-shell vehicle. The forming method of the track shoe for the tracked thin-shell vehicle comprises the following steps that a conjoined track shoe forging die is designed, the conjoined track shoe forging die comprises an upper die and a lower die, a profiled groove between the upper die and the lower die comprises a pre-forging profiled groove and a finish-forging profiled groove, the same structures of the finish-forging profiled groove and the pre-forging profiled groove are same except a flash groove; forging a conjoined track shoe hot forge piece is carried out, a blank is heated and then put into the pre-forging profiled groove of the conjoined track shoe forging die and pre-forming is carried out, so that the pre-forging profiled groove is filled with the blank when pre-forging the blank is carried out; and a pre-forged piece is placed in the finish-forging profiled groove of the conjoined track shoe forging die, and redundant metal fills the flash groove. According to the forming method of the track shoe for the tracked thin-shell vehicle, a conjoined track shoe part is manufactured through one forge piece, the labor intensity of workers is reduced, the working hours are saved, the problem that the breakage of a track occurs due to tailor welding is effectively solved, the service life of a productis prolonged, welding is reduced, the use and maintenance cost of a user is reduced to the maximum extent; and the pre-forging profiled groove and finish-forging profiled groove structure of the conjoined track shoe forging die is adopted, one set of forging die is achieved, and the production efficiency is improved.

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...
