Complex structure reverse-flow valve core and numerical control processing method thereof

Abstract

The invention relates to a complex structure reverse-flow valve core and a numerical control machining method of the complex structure reverse-flow valve core, and belongs to the technical field of mechanical parts and machining. The complex structure reverse-flow valve core comprises a valve body and a valve head. The valve head is connected to the upper end of the valve body. A stepped through hole is formed in the valve head. A straight through hole is formed in the valve body. The stepped through hole communicates with the straight through hole. An irregular boss is arranged outside the valve body. Compared with the prior art, according to the complex structure reverse-flow valve core and the numerical control machining method, due to the adoption of area-based milling, cutter jumpingcaused by the existence of a boss is effectively avoided, and the moving path of a cutter is shortened. Layer-based milling is adopted by rough machining, so that the abrasion of the cutter is greatlyreduced, cutter breaking and burning are avoided, the service life of the cutter is prolonged, and the production cost is reduced. The pertinence and adjustability of the method are guaranteed through region drawing at a step three and an offset curve at a step five.

Description

technical field [0001] The invention belongs to the technical field of mechanical parts and processing, and in particular relates to a counterflow valve core with a complex structure and a numerical control processing method thereof. Background technique [0002] The check valve refers to the valve that relies on the flow of the medium itself to automatically open and close the disc to prevent the backflow of the medium, also known as the check valve, one-way valve, reverse flow valve, and back pressure valve. The check valve is a kind of automatic valve, its main function is to prevent the reverse flow of the medium, the reverse rotation of the pump and the drive motor, and the discharge of the container medium. The existing plastic reverse flow valves are only used for gas transmission, not for liquid transmission, and have low structural strength, which cannot meet the use requirements. [0003] Patent CN208997354U discloses a reverse flow pressure reducing valve, which ...

Problems solved by technology

Due to the complex shape of some special spools, it is easy to make the product processing not in place with traditional processing technology, especially the complex curved surface contour processing on the side wall is difficult and time-consuming, which restricts the processing efficiency of parts. Traditional processing The method has unfavorable factors such as severe tool jumping and long tool path, which is a major problem in parts processing and manufacturing. This technology has always attracted attention
