Abstract

The invention relates to a mechanical production process, in particular to a production and material processing process for a solenoid valve core. A machining process for a precise solenoid valve core comprises the following steps: blanking, primary forging and pressing, secondary forging and pressing, third-time forging and pressing, extrusion for removing burrs, thermal refining, milling, drilling, reaming, extruding, turning, grinding and surface grinding. The invention provides a machining process for the precise solenoid valve core, which is good in manufacturability and high product percent of pass, and the produced valve core is high in size dimension and excellent in mechanical properties.

Description

technical field [0001] The invention relates to a mechanical manufacturing process, in particular to a manufacturing and material processing process of a solenoid valve core. Background technique [0002] The spool is used to control the fluid inside the solenoid valve, and has high dimensional accuracy and comprehensive performance. The traditional spool manufacturing process is complicated, and no unified standard has been achieved, resulting in low product qualification rate and low production efficiency. Contents of the invention [0003] The object of the present invention is to provide a processing technology for the spool of a precision solenoid valve. The spool is used to control the fluid inside the solenoid valve and has high dimensional accuracy and comprehensive performance; the processing technology proposed by the present invention meets the requirements of the valve Under the premise of core processing accuracy, the efficiency is improved and the quality of...
