Rolling and roundness correcting all-in-one machine

Abstract

The invention discloses a rolling and roundness correcting all-in-one machine. The rolling and roundness correcting all-in-one machine comprises a machine body, a mandrel, a rolling wheel and a rubberroller, wherein one end of the mandrel is arranged on the machine body, and the mandrel is annularly sleeved with a to-be-machined workpiece; the rolling wheel is arranged above the mandrel, and therolling wheel can move in the length direction of the mandrel; the grinding wheel is pushed by a first pushing mechanism to get close to the mandrel so as to grind the workpiece, so that the weld joint generates plastic deformation; and the rubber roller is arranged on the machine body, the rubber roller is pushed by a second pushing mechanism to get close to the mandrel, and the rubber roller isdriven by a motor to rotate. The rolling and roundness correcting all-in-one machine is diversified in structure, welding joint grinding and roundness correction can be carried out, the mandrel servesas a mandrel for rolling and a mandrel for grinding, the whole equipment is simple in mechanism and small in size, the occupied space of the equipment is saved, two original procedures are saved to one procedure, personnel are reduced, turnover is reduced, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of rolling and rolling calibration equipment. More specifically, the present invention relates to an all-in-one machine for rolling, compacting and correcting circles. Background technique [0002] In the metal pipe industry, especially the automobile exhaust pipe production industry, the rounding machine and the welding seam rolling machine are widely used. After the metal round pipe is produced, in order to solve the problems of unattractive appearance, large residual stress, easy corrosion and easy residual pollutants caused by the weld seam, a weld seam rolling machine is often used to use the steel between the rolling roller and the mandrel. The permanent pressure makes the welding seam of the workpiece produce plastic deformation, and eliminates stress and pores to make the welding seam smooth. After rolling, in order to ensure the roundness of the metal tube, it is necessary to go through a roundness calibrat...
