Long-axis part radial and end automatic extrusion forming system and forming method thereof

Abstract

The invention discloses a long-axis part radial and end automatic extrusion forming system and a forming method thereof. The system comprises a frame, a radial forging mechanism, a heating mechanism and an end forming mechanism, wherein the radial forging mechanism is movably arranged on the frame, and the heating mechanism and the end forming mechanism are symmetrically arranged on two sides of the radial forging mechanism respectively. When in forming, firstly, rods are placed into the radial forging mechanism, and the middles of the rods are radially formed by coordinated movement of a plurality of radial servo driving independent forging work units; secondly, blanks are clamped by the forging mechanism and integrally move to a heating area along guide rails, and ends of parts are heated; finally, the parts integrally move to an end forming area and are held by a holding mechanism, and the ends are extruded by extrusion rods and correspondingly deform. Compared with a traditional method, the method has the advantages that the logistic transfer process of middleware is omitted, manufacturing processes are intensified, production efficiency is improved, manufacturing cost is saved, only one-step clamping and positioning are needed in the whole process, coaxiality of the long-axis parts is greatly improved, and automation is facilitated.

Description

technical field [0001] The invention relates to a technology in the field of mechanical processing, in particular to an automatic radial and end extrusion forming system and a forming method of long shaft parts. Background technique [0002] In the modern manufacturing industry, there are more and more applications of long-shaft parts. Some long-shaft parts have the characteristics of unequal cross-section steps in the middle area, and the two ends of the shaft have features such as teeth or flanges. At present, the general processing method of this kind of parts is to first complete the variable diameter processing in the middle area by forging, and then machine the end features; The cross section is deformed in the direction, and then the ends of the blank are sequentially formed. In order to increase the plastic deformation capacity of the material before the end is formed, it is sometimes necessary to locally heat the end of the blank. During the billet movement, manual...
