Description

Turning device for ring forging Technical Field The invention relates to the technical field of ring forging processing, in particular to a turning device for ring forging. Background The ring forging is used as a core basic component of equipment such as a wind power flange, a bearing ring, a slewing bearing and the like, and the turning quality of the ring forging directly influences the subsequent assembly precision and the service life. At present, the turning of the ring forging mainly adopts a horizontal or vertical lathe, the workpiece is fixed by outwards tightening an electric chuck from the inner hole wall, and then the turning of the characteristics of the excircle, the end face, the groove and the like is completed by feeding a cutter. With the continuous development of automation technology, part of turning equipment has begun to integrate auxiliary functional modules to improve machining efficiency and automation level. However, the existing turning technology for ring forging mainly has the following defects: 1. in the turning process, particularly in the junction of the end face and the excircle, the ring forging is easy to form flanging burrs. The current conventional machining mode is mostly finished by deburring by using a polishing tool after turning or transferring to an independent polishing station. The off-line processing mode not only increases the process circulation time and labor cost, but also leads to the change of positioning reference easily caused by repeated clamping, and influences the size consistency of parts; 2. On the one hand, a large amount of metal chips and polishing dust generated in the turning and subsequent treatment processes are easy to splash to a workbench and the surrounding environment, so that the cleaning difficulty is increased, the operation safety is affected, on the other hand, if the fine chips adhere to the surface or clamping surface of a workpiece, the fine chips can be pressed into the machined surface to form indentations or scratches when the workpiece rotates or is clamped, and the surface quality is reduced. The existing lathe is partially provided with a dust collection device, but is mostly provided with independent modules, has weak linkage with the machining process, and lacks an integrated solution for simultaneously integrating turning, polishing, unloading and chip collection in a limited space. 3. The unloading process is easy to cause damage to the workpiece and the clamp, and part of the prior art attempts to integrate polishing and unloading functions into the same executing mechanism, but the mechanism and the control are complex due to the fact that independent driving or complex switching structures are adopted. For this purpose, we propose a turning device for ring forgings. Disclosure of Invention The invention aims to solve the problems in the prior art and provides a turning device for ring forgings.
