Abstract

The invention provides a segmented jaw for a reducing machine. The segmented jaw comprises an upper clamp body and a lower clamp body, and a jaw body of the upper clamp body and a jaw body of the lower clamp body are each formed by splicing a plurality of inserts. The inserts are fixed to the upper clamp body and the lower clamp body. A horizontal key groove is formed in the middle of each insert, longitudinal key grooves are further formed in the two ends of each insert correspondingly, and the upper clamp body and the lower clamp body are provided with key grooves corresponding to the horizontal key grooves and the longitudinal key grooves correspondingly. The inserts are positioned on the upper clamp body and the lower clamp body through the horizontal key grooves and the longitudinal key grooves, and the inserts are connected with the upper clamp body and the lower clamp body through keys. According to the segmented jaw for the reducing machine, the jaw needing to bear pressure in the production process is formed by splicing the inserts, and therefore only the inserts on the clamp bodies bear pressure; only the inserts need to be replaced after abrasion, the segmented jaw does not need to be replaced, so that repairing cost is lowered, and work efficiency is improved; the inserts are small in size, the thermal treatment hardness can be increased, and the service life is prolonged.

Description

technical field [0001] The invention relates to a clamping jaw of a diameter reducing machine, in particular to a segmented jaw for a diameter reducing machine. Background technique [0002] The clamping jaw of the existing reducing machine adopts an integral structure. After the jaw is worn out, the positioning accuracy of the parts is affected, and the machining accuracy is affected. It needs to be replaced as a whole, which is costly, time-consuming and laborious; For various large workpieces, the jaws need to be replaced, which is time-consuming and labor-intensive. Contents of the invention [0003] The purpose of the present invention is to provide a segmented jaw for a reducing machine, which can meet the needs of the reducing machine to quickly replace the jaws in the production process of various products, improve work efficiency and processing accuracy, and increase the life of the jaws . [0004] In order to solve the above-mentioned technical problems, the te...
