Valve body machining method and valve body

Abstract

The invention belongs to the technical field of valve body machining, and discloses a valve body machining method and a valve body. The valve body machining method comprises the steps that S1, a three-dimensional model of the valve body is established, and an oil duct is formed in the three-dimensional model of the valve body; s2, slicing and segmenting the three-dimensional model of the valve body to form a plurality of sheet-shaped valve bodies, and forming section holes of the oil duct in the plurality of sheet-shaped valve bodies; s3, the multiple plates are in one-to-one correspondence with the multiple sheet-shaped valve bodies, and section holes of the oil ducts are correspondingly machined in all the plates; and S4, the multiple plates are stacked and connected together, and the valve body with the oil duct is formed. Compared with the prior art that numerical control electric machining equipment is used for directly drilling holes on the valve body, marking and drilling an oil duct, the machining method of the valve body, provided by the invention, occupies less space in the valve body, can arrange a more complex oil duct in the valve body, and can be used for machining the oil duct, so that the machining efficiency is improved. And the sand removal of the cast oil duct or the feed path of machining does not need to be considered, so that the oil duct machining process is simplified.

Description

technical field [0001] The invention relates to the technical field of valve body processing, in particular to a valve body processing method and the valve body. Background technique [0002] Valve body processing is divided into shape processing and internal oil passage processing. The shape is processed by casting or forging steel block, and the internal oil passage is obtained by combining casting and machining or pure machining. There is an oil passage in the valve body to supply the oil circulation. The existing oil passage processing in the valve body is mainly to directly drill holes on the valve body and mark the oil passage through the numerical control electric processing equipment, such as figure 1 As shown, when the numerical control electric machining equipment is processing, the oil passages processed are right-angle oil passages, which not only have a large pressure loss, but also occupy the space in the valve body, so only a simple oil passage distribution c...

There is an oil passage in the valve body to supply the oil circulation. The existing oil passage processing in the valve body is mainly to directly drill holes on the valve body and mark the oil passage through the numerical control electric processing equipment, such as figure 1 As shown in Fig. 1, the oil channel processed by CNC electric machining equipment is a right-angle oil channel, which not only has a large pressure loss, but also takes up space in the valve body, and can only realize simple oil channel distribution.
