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

A kind of manufacture method of valve body
Technical field
The present invention relates to a kind of manufacture method of valve body.
Background technology
Existing gas valve valve body is normally made through grinding and Drilling operation by after raw material die cast again, and need in die cast process to heat raw material, each manufacturing firm is needed to be equipped with a set of Casting Equipment, add equipment cost and cause the waste of the energy, small-scale heating and extrusion process also can produce larger industrial pollution, these industrial pollution are processed and needs at substantial fund, and, in extrusion process, single mould can only die casting accessory, production efficiency is slower, and at present along with the raising of automaticity, blank forming speed goes is fast, the blank speed of response of extrusion process has been difficult to the process velocity of catching up with blank, thus dragged slowly the speed of production of valve body.On the other hand, be limited to the process conditions of die casting on a small scale, current valve body major part can only adopt the die casting aluminium manufactures such as ADC12, the limited performance of valve body and the material property of die casting aluminium, is difficult to effectively be promoted.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of manufacture method effectively can enhanced productivity, improve valve body performance, reduce the valve body of production cost.
The present invention is the technical scheme that its technical problem of solution adopts:
A manufacture method for valve body, comprises the following steps:
The first step, by raw metal hot melt and extruded be the section bar of strip;
Second step, cuts into some sections of blanks by described section bar, the shape of blank and the mating shapes of valve body;
3rd step, carries out grinding and Drilling operation to blank, obtains valve body.
Preferably, described raw metal is aerolite.
Preferably, described raw metal is 4032 aluminium alloys or 7075 aluminium alloys or 6061 aluminium alloys.
Preferably, the cross sectional shape of described aluminium section bar and the projection of shape of valve body left and right directions match, and the face that cuts of section bar is perpendicular to the length direction of section bar, and the length of blank is equal to or greater than the Breadth Maximum of valve body left and right directions.
The invention has the beneficial effects as follows: after adopting manufacture method of the present invention, the step of product moulding can be concentrated in existing most section bar production plant and carry out, and valve body manufacturing firm only need cut section bar, the cold working such as grinding and boring, and without the need to optional equipment Equipment for Heating Processing, reduce equipment and production cost, improve production efficiency, decrease pollution and energy consumption, energy-conserving and environment-protective simultaneously; On the other hand, because current professional section bar production plant has relatively large profile production equipment, the better raw metals of performance such as aviation aluminium therefore can be adopted to make section bar, effectively can improve the performance of valve body, thus improve the market competitiveness of enterprise.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is flow chart of the present invention.
Detailed description of the invention
With reference to Fig. 1, a kind of manufacture method of valve body, comprises the following steps:
The first step, by raw metal hot melt and extruded be the section bar of strip; This step can be concentrated and carry out in existing section bar production plant, and valve body manufacturing firm then without the need to without the need to optional equipment Equipment for Heating Processing, reduces equipment and production cost, improves production efficiency, decreases pollution and energy consumption, energy-conserving and environment-protective simultaneously.
Second step, cut into some sections of blanks by section bar, the shape of blank is more bigger than valve body with the mating shapes of valve body, is convenient to processing, also can reduces the waste of material.
3rd step, carries out grinding and Drilling operation to blank, obtains valve body, also can increase glossing again, makes the surface of valve body more smooth and attractive in appearance.
In the present embodiment, the cross sectional shape of aluminium section bar and the projection of shape of valve body left and right directions match, the face that cuts of section bar is perpendicular to the length direction of section bar, and the length of blank is equal to or greater than the Breadth Maximum of valve body left and right directions, be convenient to cut and process, can enhance productivity, reduce waste of material.
In the present embodiment, raw metal is aerolite, because current professional section bar production plant has relatively large profile production equipment, hot melt and shaping can be carried out to aerolite, the more traditional cast aluminum of aerolite has better material property, effectively can improve the performance of valve body, thus improve the market competitiveness of enterprise.Raw metal is preferably 4032 aluminium alloys or 7075 aluminium alloys or 6061 aluminium alloys, this different materials is indeformable after having excellent processing characteristics, excellent plating resistance and good corrosion resistance, toughness and processing, the fine and close zero defect of material and be easy to the good characteristics such as polishing, colouring film is easy, oxidation effectiveness is splendid, the needs of current most of gas valve can be adapted to, certainly, in practical application, raw metal also can select other common used materials such as stainless steel.
The foregoing is only preferred embodiments of the present invention, as long as the technical scheme realizing the object of the invention with basic same approach all belongs within protection scope of the present invention.
