Abstract
The invention discloses a kind of antirust ball valve core drawing manufacturing process, belong to valve manufacture field.This antirust ball valve core drawing manufacturing process comprises the following steps: select materials, solution treatment, drawing, pressure ball, insert interior straight tube, polish, clean, the step such as spray-on coating, reliable by processing technique, it is achieved finished product spool is more reliable.
Description
Technical field
The present invention relates to valve manufacture field, a kind of antirust ball valve core drawing manufacturing process.
Background technology
Valve is widely used in modern society.Particularly in water heating pipe fittings technical field, the valve of prior art has
A variety of, mainly there are ball valve, angle valve, stop valve etc., wherein ball-valve structure is relatively simple, and the mainly spool of ball valve is simpler
Single.The spool of ball valve chondritic the most symmetrically, there is the cylindric through hole of a through entirety centre, outside spool
Sphere centre position laterally has the valve rod groove that is connected with valve rod, and the when of work, rotation valve rod makes the cylinder of spool
The import and export of shape through-hole alignment ball valve, the when of quitting work, rotate backward the turnover that valve rod makes the sphere alignment ball valve of spool
Mouthful.Relatively simple for structure due to ball valve, easy to operate.So applying widely at valve technology field.And realize ball
The major part of the sealing function of valve is spool, and the sealing ring coordinated with it, and the spool of ball valve abrasion occurs or just ruptures
Easily reveal, make whole ball valve scrap, therefore improve antirust ball valve core drawing manufacturing process so that it is be more reliable the most aobvious
Obtain particularly necessary.
Summary of the invention
It is desirable to provide a kind of antirust ball valve core drawing manufacturing process, reliable by processing technique, it is achieved finished product
Spool is more reliable.
For achieving the above object, technical scheme is as follows:
A kind of antirust ball valve core drawing manufacturing process, it is characterised in that comprise the following steps:
Select materials: select 304 stainless steel materials as blank, carry out Size calculation according to spool size, then use cutting machine according to
Blank is cut by the target size after calculating；
Solution treatment: by with process after pipe carry out solution treatment, keep temperature 1050 DEG C, 15 minutes persistent period, then
Quickly cooling；
Drawing: the blank after polishing is placed on mould, opens clapper die spotting press, be warming up to 550 DEG C ~ 650 DEG C, carry out hot-drawn for the first time
Deeply, after Hot drawing, carry out above-mentioned solutionizing step for the first time again, then blank is placed in mould carries out second time Hot drawing, by two
After secondary Hot drawing blank carry out third time Hot drawing school shape until obtaining regular spherical shell, when third time Hot drawing school shape
Carry out pressurize process；
Insert interior straight tube: in selection, logical and external diameter is less than 304 stainless steel tubes of spherical shell latus rectum, be cut to spherical outside
Shell latus rectum is isometric, uses straight tube in the tapered punch punching press expansion on punch press or stamping machine, makes interior straight tube be connected with spherical shell
Form finished product spool together；
Polishing: carry out surface polishing, sanding burr totally and is polished；
Clean: the spool made is put in acid solution, keeps 15 minutes, finally take out and rinse；
Basecoat paint: to surface spraying/roller coating prime paint, prime paint is white fused alumina sand grains, and is dried 30 minutes；
Surface lacquer sprays: at prime paint surface laser spraying of wearable coating, described wear-resistant coating is tungsten carbide coating, is dried 0.5-
After 1.5 hours, repeat to spray three times.
Further, described drawing step, after obtaining spherical shell, opens one in the centre position of spherical case surface
Vertical masonry joint backlash extrudes valve rod groove, or outputs valve rod groove at the centre position milling cutter of spherical case surface.
Further, described drawing step, in forming process, needs after each drawing to carry out the drawing state of part
Observation, need to carry out smoothing wrinkle process if there is fold, then carry out drawing next time.
The beneficial effects of the present invention is: use 304 rustless steels, can effective anticorrosive oxidation, it is to avoid spool is at specific ring
The problem that in border, service life shortens, have employed acid solution and is carried out, and goes out the iron filings on top layer, is allowed to more attractive.The present invention
Manufacture method the most significantly save material, reduce the cost of ball valve core；And the ball valve core precision made, thickness
Degree, integrity can be guaranteed, and valve rod connects the intensity of seat and valve rod junction and is improved.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described.
A kind of antirust ball valve core drawing manufacturing process, comprises the following steps: select materials: select 304 stainless steel materials conducts
Blank, carries out Size calculation according to spool size, is then cut by blank according to the target size after calculating with cutting machine；Solid solution
Process: by with process after pipe carry out solution treatment, keep temperature 1050 DEG C, 15 minutes persistent period, then fast quickly cooling
But；Drawing: the blank after polishing is placed on mould, opens clapper die spotting press, be warming up to 550 DEG C ~ 650 DEG C, carry out hot-drawn for the first time
Deeply, after Hot drawing, carry out above-mentioned solutionizing step for the first time again, then blank is placed in mould carries out second time Hot drawing, by two
After secondary Hot drawing blank carry out third time Hot drawing school shape until obtaining regular spherical shell, when third time Hot drawing school shape
Carry out pressurize process.Described drawing step, in forming process, needs after each drawing to be observed the drawing state of part,
Smoothing wrinkle process need to be carried out if there is fold, then carry out drawing next time.After obtaining spherical shell, in spherical case surface
Centre position is opened vertical masonry joint backlash and is extruded valve rod groove, or outputs valve rod groove at the centre position milling cutter of spherical case surface.
Insert interior straight tube: selection is led to and external diameter is less than 304 stainless steel tubes of spherical shell latus rectum, be cut to lead to spherical shell
Footpath is isometric, uses straight tube in the tapered punch punching press expansion on punch press or stamping machine, makes interior straight tube and spherical shell be connected in one
Rise and form finished product spool；Polishing: carry out surface polishing, sanding burr totally and is polished；Clean: the spool made is put into acid
In solution, keep 15 minutes, finally take out and rinse；Basecoat paint: to surface spraying/roller coating prime paint, prime paint is white firm
