Valve body manufacturing method

Abstract

The invention discloses a valve body manufacturing method. The valve body manufacturing method includes the following steps that firstly, raw metal materials are subjected to hot melting and extrusion forming to form long-strip-shaped profiles; secondly, the profiles are cut into a plurality of blanks, wherein the blanks are matched with valve bodies in shape and are slightly larger than the valve bodies; and thirdly, the blanks are ground and drilled to obtain the valve bodies. According to the manufacturing method, due to the fact that the profile forming step can be performed in most of existing profile production plants in a concentrated mode, and valve body manufacturers only need to perform cold machining such as cutting, grinding and drilling on the profiles without additionally arranging heat treatment equipment, the equipment and production cost is reduced, production efficiency is improved, meanwhile, pollution and energy consumption are reduced, and energy conservation and environment protection are archived; besides, due to the fact that existing professional profile production plants have large profile production equipment, raw metal materials such as aviation aluminum with better performance can be adopted for manufacturing the profiles, the performance of the valve bodies can be effectively improved, and the market competitiveness of enterprises can be effectively improved.

Description

technical field [0001] The invention relates to a manufacturing method of a valve body. Background technique [0002] Existing gas valve bodies are usually made of raw materials after die-casting and then grinding and drilling. In the process of die-casting, the raw materials need to be heated, and each manufacturer needs to be equipped with a set of casting equipment, which increases the The cost of equipment and waste of energy, small-scale heating and die-casting process will also produce large industrial pollution, and it will cost a lot of money to deal with these industrial pollution, and in the die-casting process, a single mold can only die-cast one part, The production efficiency is relatively slow, and at present, with the improvement of the degree of automation, the processing speed of the blank is getting faster and faster, and the output speed of the blank in the die-casting process has been difficult to keep up with the processing speed of the blank, thus slowi...

[0002] Existing gas valve bodies are usually made of raw materials after die-casting and then grinding and drilling. In the process of die-casting, the raw materials need to be heated, and each manufacturer needs to be equipped with a set of casting equipment, which increases the The cost of equipment and waste of energy, small-scale heating and die-casting process will also produce large industrial pollution, and it will cost a lot of money to deal with these industrial pollution, and in the die-casting process, a single mold can only die-cast one part, The production efficiency is relatively slow, and at present, with the improvement of the degree of automation, the processing speed of the blank is getting faster and faster, and the output speed of the blank in the die-casting process has been difficult to keep up with the processing speed of the blank, thus slowing down the production speed of the valve body

On the other hand, limited to the technological conditions of small-scale die-casting, most of the current valve bodies can only be made of die-casting aluminum such as ADC12. The performance of the valve body is limited and the material properties of die-casting aluminum are difficult to be effectively improved.
