Abstract

The invention relates to the field of fire products, in particular to a method for manufacturing a fire extinguisher valve body. By means of the method, a zinc alloy valve body blank is obtained through die-casting, the process steps of metalworking, nickel plating, copper plating, coloring and sealant applying are executed, and then the fire extinguisher valve body is made of zinc alloy instead of copper as an improvement; thus, the cost of the fire extinguisher valve body is reduced, and the precious copper metal is saved; meanwhile, by means of the method, the production time can be well shortened, the manufacturing process is excellent compared with the manufacturing process of an existing copper valve body, and the appearance is comparable with that of the copper valve body.

Description

A kind of manufacture method of fire extinguisher valve body
Technical field
The present invention relates to the manufacture method in fire product field, particularly a kind of fire extinguisher valve body.
Background technology
Extinguisher valve door is mainly made up of valve body, spool, spring, handgrip part.At present, because the valve body of fire extinguisher adopts brass manufacture, cause the cost of raw material of valve body very high, and kirsite because meeting, performance substitute brass making valve body, lower cost for material, but the current manufacture method of also not manufacturing fire extinguisher valve body with kirsite.
Summary of the invention
(problem that invention will solve)
Object of the present invention, being, for addressing the above problem, provides a kind of manufacture method of fire extinguisher valve body, realizes fire extinguisher valve body is improved to and is adopted kirsite to manufacture by brass manufacture, reduces fire extinguisher valve body cost, saves more valuable copper metal.
(technical scheme of dealing with problems)
For achieving the above object, the present invention has adopted following technical scheme:
A manufacture method for fire extinguisher valve body, it comprises the steps:
The first step, design and the compression mod of processing described fire extinguisher valve body;
Second step, uses die casting machine die casting to go out the kirsite blank of described fire extinguisher valve body;
The 3rd step, carries out metalworking to die casting described fire extinguisher valve body blank out: respectively essential turning, boring, tapping processing are carried out in relevant position;
The 4th step, the described fire extinguisher valve body after metalworking is carried out to following electroplating processes successively:
First, nickel plating;
Next, then copper facing;
Again, carry out painted work, imitate gold;
The 5th step, external application sealer, gives extraordinary varnish on described fire extinguisher valve body.
The invention has the beneficial effects as follows:
Adopt after the manufacture method of described a kind of fire extinguisher valve body, can utilize well kirsite to manufacture the work of described fire extinguisher valve body, tool has the following advantages:
The first, adopt described manufacturing process, can finely carry out zinc alloy diecasting operation, and after plating and upper sealer, described fire extinguisher valve body outward appearance can compare favourably with brass body;
Second, originally adopt brass bar, experience from bar blanking, blowtorch heating, jumping-up, extrusion modling, metalworking operation, not only single-piece total time used time of carrying out the work is long, and output is little, and adopt described manufacture method with after zinc alloy diecasting, bore portion whole die casts except the aperture of logical gauge stand that valve body is contained, the workload of follow-up metalworking is little, so, described fire extinguisher valve body blank quality, output is high, when plating, also can carry out in batches, therefore described worker artistic skill shortens the production time admirably, manufacture method than former brass body is superior.
Brief description of the drawings
Further illustrate with figure below in conjunction with requirement of the present invention:
Fig. 1 is the valve body surface structure schematic diagram of the manufacture method die cast of described a kind of fire extinguisher valve body;
Fig. 2 is the half sectional view of the finished product of the manufacture method manufacture of described a kind of fire extinguisher valve body.
Detailed description of the invention
The manufacture method of described a kind of fire extinguisher valve body is as follows:
The first step, design and the compression mod of processing described fire extinguisher valve body, mould can be designed as one and goes out four structures;
Second step, uses die casting machine die casting to go out the kirsite blank of described fire extinguisher valve body;
The 3rd step, carries out metalworking to the kirsite blank of die casting described fire extinguisher valve body out: respectively essential turning, boring, tapping processing are carried out in relevant position;
The 4th step, the described fire extinguisher valve body after metalworking is carried out to following electroplating processes successively:
First, nickel plating;
Next, then copper facing;
Again, carry out painted work, imitate gold;
The 5th step, external application sealer, gives extraordinary varnish on described fire extinguisher valve body.
After above-mentioned processing step, described fire extinguisher valve body can be used for follow-up assembly process.
