A hydraulic valve deburring process

Abstract

The invention provides a deburring process of a hydraulic valve. The deburring process of the hydraulic valve is characterized by comprising the following steps that firstly, heavy boring is carried out, and specifically heavy boring treatment is carried out on a workblank hole of hydraulic valve holes so that chambering can be achieved; secondly, semi-fine boring is carried out, and specificallymachining is carried out from a segment of the hole needing to be machined of the hydraulic valve holes gradually to the other end; thirdly, reaming is carried out, and specifically a bottoming reamerwith a guiding single blade is selected to carry out reaming treatment on the valve hole; fourthly, an undercutting groove is milled, and generated burrs are perpendicular to an axis; and fifthly, magnetic grinding is carried out, the hydraulic valve is inserted into a gap between two magnetic poles, the gap is filled with magnetic abrasive materials, and the cylindricity and the surface roughness of the valve hole of the hydraulic valve are corrected. The deburring process of the hydraulic valve has the beneficial effects that automatic and efficient high-quality washing and deburring of a workpiece are achieved, the machining efficiency is improved, the geometric position precision of the complex hole is also guaranteed, generation of the burrs is also restrained well, higher-quality and higher-performance valve holes are manufactured, and therefore the working efficiency and the working performance of the hydraulic valve are further improved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic parts, and in particular relates to a hydraulic valve deburring process. Background technique [0002] During the processing of metal parts, burrs will occur at the junction of the processing surfaces. For a long time, the burr problem has not been well solved, mainly for two reasons: (1) People have not paid enough attention to it. Although the deburring process has been adopted in the part processing technology, the burr problem has not been solved by strict requirements ; (2) It is very difficult to deburr some mechanical parts with high precision or complex shape. For example, the rounding radius of hydraulic servo valve reaches 0.002 mm, and some multi-way valve housings have many cross holes and shoulders. holes, blind holes, etc. As people have higher and higher requirements for product performance and appearance, burrs have become a direct or potential factor affecting product performa...

Problems solved by technology

For a long time, the burr problem has not been solved well. There are two main reasons: (1) People have not paid enough attention to it. Although the burr removal process has been adopted in the part processing technology, it has not been strictly required to solve the burr problem. ; (2) It is very difficult to deburr some mechanical parts with high precision or complex shape. For example, the rounding radius of hydraulic servo valves reaches 0.002 mm, and some multi-way valve housings have many cross holes and shoulders. Holes, Blind Holes, etc.

After reaming, the generated burr is in the same direction as the axis of the hole and sinks in the sinking groove, which is difficult to remove
