Abstract

The invention discloses a stretcher jaw and a machining process thereof. The stretcher jaw comprises an upper jaw base, a first tooth surface insert, a lower jaw base and a second tooth surface insert, wherein the upper jaw base is provided with a first mounting groove in the lower side; the first tooth surface insert is detachably mounted in the first mounting groove; the lower surface of the first tooth surface insert is a first tooth surface for clamping workpieces; the first tooth surface is projected out of the first mounting groove; a second mounting groove is formed in the upper side of the lower jaw base; the second tooth surface insert is detachably mounted in the second mounting groove; the upper surface and / or the lower surface of the second tooth surface insert are second tooth surfaces for clamping the workpieces; and the second tooth surfaces are projected out of the second mounting groove. The tooth surfaces of the jaw are separated out to combine with the jaw bases in an insert form, so that the purchase cost caused by damage of the tooth surfaces of the stretcher jaw is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a jaw of a stretching machine and a processing technology of the jaw of a stretching machine. Background technique [0002] The jaw of the 1500-ton stretching machine is the most important tool in the stretching process. Its reasonable and effective use has a decisive impact on the product's external dimensions and residual stress relief. [0003] The stretching jaws in the prior art have an integral structure, and the thickness specifications range from 380 to 500 mm. The price of each new jaw is about 45,000-55,000 yuan. The main problems of the jaws of the stretching machine are rapid failure, short service life and high production cost. The annual consumption of jaws is generally more than 20 pieces, and one of the main manifestations of its failure is tooth surface wear. [0004] Therefore, how to solve or improve the problem of high production cost caused b...
