Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. See attached Figure 4 to 8 Shown.

[0022] The present invention is realized through the following technical solutions: A forging: ① blanking; ② heat treatment, heating for 5 to 7 hours, and the temperature reaches 1000 ℃ to 1300 ℃, the inside and outside of the workpiece are evenly heated; ③ pre-pressing, the workpiece after heat treatment is placed Enter the lower die of the forging press and leave the heating furnace for no more than ...

Abstract

The invention relates to the technical field of equipment manufacturing industries, in particular to a machining method of a forge piece jaw base. According to the technical scheme, the method comprises the steps that A forging is carried out, wherein (1) blanking, (2) heat treatment, (3) prepressing, (4) forging and pressing, (5) pushing out and (6) cooling are included; and B turning is carried out. The method has the advantages that air holes, sand holes and damage caused by the holes are reduced; the mechanical property of metal is improved, and the internal structure of the metal is improved; labor productivity is improved; precision die forging is used, so the forge piece size is proper, and waste during cutting machining is lowered; and crystalline grains are relatively small, even, compact and suitable for following mechanical cutting machining, organization preparation is achieved for final heat treatment, and part using performance can be well improved.

Description

Technical field [0001] The invention relates to the technical field of equipment manufacturing, in particular to a method for processing a jaw base of a forging. Background technique [0002] Large jaws are mostly used on large machine tools to clamp large workpieces to be processed. The jaw base is used to clamp the jaws. It belongs to the technical field of machinery and equipment manufacturing. The jaws are divided into two or four petals. , The present invention is a jaw base specifically for four-petal jaws. At present, the well-known jaw base is formed by integral casting for the pipe fittings, see attached figure 1 , Process the inner and outer circles of the pipe fittings to the surface accuracy requirements, mark the cutting auxiliary lines on the surface of the pipe fittings and cut them into four monoliths, and then mark the auxiliary lines and drill holes on the monoliths one by one. After assembly, mark Edge and milling to complete processing. The metallographic st...
