Abstract

The invention discloses an upsetting and stretching device for an annular blank for prefabricating a hollow steel ingot, relating to an upsetting and stretching device for an annular blank and aims at solving the technical problem that the annular blank is not easily and axially upsetaxial upsetting of the annular blank is not easy to realize in the prior art. The upsetting and stretching device is composed of an upsetting device and a stretching device which are placed on a workbench of a pressing machine, wherein the upsetting device is composed of a mandrel, an upper backing ring, a lower backing ring and N hollow connecting rods; the mandrel is composed of a mandrel chuck, a mandrel disk flange and a mandrel cylinder; and the stretching device is composed of an upper stretching anvil arranged mounted on a walking beam of the pressing machine and a lower stretching anvil arranged on the workbench of the pressing machine. By using the upsetting and stretching device for the annular blank for prefabricating the hollow steel ingot, a repeated upsetting and stretching device technology for an annular blank for prefabricating a hollow steel ingot can be achieved, the heating number is reduced, the process is simplified, the product performance is improved, and the production efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of thermal processing of metal materials, and in particular relates to a device for upsetting and elongating ring-shaped blanks prefabricated by hollow steel ingots. Background technique [0002] Ring forgings are commonly used parts in machinery manufacturing and have a wide range of applications. Traditionally, ring forgings are made of solid steel ingots, and the basic process is: upsetting—punching—drawing—reaming. Hollow steel ingot has the advantages of dense structure, small segregation, good homogeneity, energy saving and material saving, etc. It has great advantages to manufacture ring forgings with hollow steel ingots, and it is a development direction of ring forging manufacturing industry. [0003] The hollow steel ingot is chamfered, pre-expanded, and shaped to form a prefabricated ring blank of the hollow steel ingot. In view of the fact that the ring-shaped blank prefabricated by the hollow ...
