Problems solved by technology

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a sleeve-based valve plug component processing method, which is used to solve the problem that the existing processing method requires multiple clamping, resulting in reduced processing accuracy, while the existing Using the radial clamping method will cause damage to the outer peripheral surface of the valve plug, and the clamping position needs to be replaced. Multiple factors lead to a decrease in the machining accuracy of the valve plug. At the same time, the existing processing method processes the valve plug and the valve stem separately. Assembled as a finished product, there are assembly errors, and the errors of each processing standard are superimposed after assembly, which further affects the quality and accuracy of the finished product

Abstract

The invention provides a processing method based on a sleeve-type valve plug component, which is used to solve the problem that the existing processing method affects the quality and precision of the finished product. It includes the following steps: the pre-processing step of the valve stem, finishing the valve stem to the finished product size; the pre-processing step of the valve plug, processing the non-peripheral surface of the valve plug to the finished product size, and processing the outer peripheral surface of the valve plug until the rough machining is completed Process; component assembly step, assemble the pre-processed valve stem and valve plug to form a semi-finished product; semi-finished product processing step, use axial clamping tooling to clamp the valve plug under axial force, with the valve stem as the benchmark, through For the roundness runout and straightness of the valve stem on the semi-finished product, the finishing cutting amount of the outer peripheral surface of the valve plug is determined and processed. It has the characteristics of high processing precision and high processing efficiency.

Description

technical field [0001] The invention relates to the field of valve processing, in particular to a method for processing a sleeve-based valve plug component. Background technique [0002] In the structural design of the sleeve valve, the valve plug part is one of the key components of this series of products, and is also the core component of each series of sleeve valves. [0003] Generally, this part is composed of a valve stem and a valve plug assembled and mechanically fastened. It has the advantages of large guiding area, good shock resistance, strong cavitation resistance and cavitation resistance. However, the base material category of this type of part is : S20910+440C; 316L+(316L+ST6); 316L+1Cr12WMoV and other substrates, that is, this type of substrate has the characteristics of high cutting heat, large linear expansion coefficient, easy sticking to the knife, and easy wear of the tool; There have always been two or more times of clamping, difficult control of size ...
