Cross-wedge rolled piece machining device and method

Abstract

The invention discloses a cross-wedge rolled piece machining device. The cross-wedge rolled piece machining device comprises a material inspection position, a sawing machine, a medium-frequency induction electric furnace, a cross-wedge rolling mill, a cooling and transporting device and a hydraulic straightening mechanism, wherein a cross-wedge rolled piece sequentially passes through the materialinspection position, the sawing machine, the medium-frequency induction electric furnace, the cross-wedge rolling mill, the cooling and transporting device and the hydraulic straightening mechanism.The invention further provides a cross-wedge rolled piece machining method. The cross-wedge rolled piece machining method comprises the following steps that material inspection is conducted; blankingis conducted, specifically, the sawing machine is used to disintegrate a workpiece; heating is conducted, specifically, a medium-frequency heating furnace is used to conduct heating treatment on the workpiece; rolling forming is conducted, specifically, the cross-wedge rolling mill is used to conduct rolling forming, and then the cooling and transporting device is used to transport the workpiece to the sawing machine and remnant removing is conducted; and straightening is conducted, specifically, a hydraulic straightening machine is used to conduct straightening. The cross-wedge rolled piece machining device has the beneficial effects that positioning disintegration is conducted through the sawing machine, the disintegration precision is improved, the workpiece is prevented from deviatingthrough a positioning device of the cross-wedge rolling mill, the cooling and transporting device enables cooling and transporting to be conducted simultaneously, the time is saved, through the self-made hydraulic straightening mechanism, the straightening precision is high, and the reliability is high.

Description

technical field [0001] The invention relates to a processing device and method for parts, in particular to a processing device and method for cross wedge rolled parts. Background technique [0002] Shaft is one of the typical parts commonly seen in machining. It is mainly used in machinery to support transmission parts such as gears, pulleys, cams, and connecting rods to transmit torque. According to different structural forms, shafts can be divided into stepped shafts, tapered mandrel shafts, optical shafts, hollow shafts, crankshafts, camshafts, eccentric shafts, various lead screws, etc. Among them, stepped transmission shafts are widely used and their processing technology can reflect them more comprehensively. Processing rules and commonality of shaft parts. [0003] According to the functions and working conditions of shaft parts, the technical requirements are mainly in the following aspects: [0004] ⑴Dimensional accuracy, the main surface of shaft parts is usuall...

AI Technical Summary

Problems solved by technology

[0012] It can be seen that as the initial shape of the cross-wedge rolled parts before roughing and finishing machining of shaft parts, the necessity of a reasonable process and device is necessary. In actual production, the cross-wedge rolled parts must go through material inspection, blanking decomposition, heating, rolling, Straightening and other processes, but there are more or less errors in each process and device, which ultimately reduces the performance of the entire cross wedge rolled piece
