Abstract

The invention relates to processing equipment for hardening a sealing surface of a valve by rolling. The processing equipment comprises a rack with an L-shaped plane; a power turning table is fixedly arranged inside the rack, the upper part of the power turning table is fixedly provided with a workpiece through a fixing part, and the rod part of the workpiece is connected with a vertical moving workbench; the vertical moving workbench is arranged at the rear side of the power turning table, the right side of the power turning table is fixedly provided with a sliding workbench through a support frame, and the power turning table is located on a vertical intersection point of the center line of the vertical moving workbench and the center line of the sliding workbench; the upper surface of the sliding workbench is provided with a rolling head part through a base, a pressing cylinder is mounted above the rolling head part, and the pressing cylinder and the rack are connected into a whole through steel plates mounted at two sides of the pressing cylinder to form a closed stressed frame; and one side of the processing equipment is provided with a control device and a hydraulic device. The processing equipment can be used for rolling the sealing surface of the valve to ensure that surfacing alloy on the sealing surface of the valve is deformed and strengthened, so that the hardness of the sealing surface is remarkably improved, the qualities of valve products are effectively improved, and the service lives of the valve products are effectively prolonged.

Description

technical field [0001] The invention relates to a processing equipment, in particular to a processing equipment for rolling the sealing surface of a valve to increase its hardness, and belongs to the technical field of rolling equipment. Background technique [0002] Valves are widely used in various fields such as industrial production, transportation, pipeline transportation, nuclear power, etc. Due to the specific working environment, such as intake and exhaust valves of internal combustion engines, valves for pipeline transportation of chemicals, the working environment of this valve is harsh, and it is usually used in high temperature And corrosive fluid medium, so the failure of this valve is mainly caused by the wear and corrosion of the sealing surface. [0003] The sealing form of the valve is usually flat or conical sealing. In order to improve the service life and working stability of the valve, this kind of valve usually needs to be surfacing with corrosion-resis...
