Abstract
The invention discloses a process for deep drawing manufacturing of a titanium ball valve core, and belongs to the field of manufacture of valves. The process for the deep drawing manufacturing of the titanium ball valve core comprises the following steps: selecting materials, annealing, performing deep drawing, pressing into a ball, placing in an inner straight pipe, cleaning and the like. By the adoption of reliable process, the manufactured valve core is relatively reliable.
Description
Technical field
The present invention relates to valve manufacture field, specifically a kind of drawing manufactures the technique of titanium material material ball valve core.
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 contains ball valve, angle valve, stop valve etc., and wherein ball-valve structure is comparatively simple, and mainly the spool of ball valve is fairly simple.The spool of ball valve chondritic symmetrically on the whole, there is the cylindric through hole of a through entirety centre, the valve rod groove that to be connected with valve rod is laterally had at the spherical outside surface center position of spool, when work, rotation valve rod makes the import and export of the cylindric through-hole alignment ball valve of spool, time out-of-work, rotate backward valve rod and make the sphere of spool aim at the import and export of ball valve.Relatively simple for structure, easy to operate due to ball valve.So in valve technology field application widely.And the major part realizing the sealing function of ball valve is spool, and the sealing ring be mated, there are wearing and tearing or break just easily revealing in the spool of ball valve, whole ball valve is scrapped, therefore improve the technique that drawing manufactures titanium material material ball valve core, make it more reliably just seem particularly necessary.
Summary of the invention
The present invention aims to provide the technique that a kind of drawing manufactures titanium material material ball valve core, reliable by processing technology, realizes finished product spool more reliable.
For achieving the above object, technical scheme of the present invention is as follows:
Drawing manufactures a technique for titanium material material ball valve core, it is characterized in that, comprises the following steps:
Select materials: select titanium material sheet material as blank, carry out Size calculation according to spool size, then according to the target size after calculating, blank is cut with cutting machine;
Annealing: the plectane after cutting is placed in annealing furnace and carries out annealing in process, annealing furnace keeps temperature more than 550 ~ 600 DEG C, 15 ~ 30 minutes duration, then cools rapidly;
Drawing: the blank after polishing is placed on mould, open clapper die spotting press, be warming up to 300 DEG C ~ 450 DEG C, carry out first time Hot drawing, above-mentioned annealing steps is carried out again for the first time after Hot drawing, again blank is placed in mould and carries out second time Hot drawing, blank after second heat drawing is carried out Hot drawing school shape for the third time and, until obtain regular spherical shell, carry out pressurize process when third time Hot drawing school shape;
Insert interior straight tube: in selecting, logical and external diameter is less than the titanium material pipe of spherical shell latus rectum, be cut to spherical shell latus rectum isometric, adopt straight tube in the tapered punch punching press expansion on punch press or stamping machine, interior straight tube and spherical shell are fixed together and form finished product spool;
Polishing: carry out surface finish, by clean for sanding burr also polishing;
Cleaning: the spool made is put into acid solution, keeps 15 minutes, finally take out and rinse.
Further, described drawing step, after obtaining spherical shell, is opened a vertical masonry joint backlash and is extruded valve rod groove, or output valve rod groove at the centre position milling cutter of spherical case surface in the centre position of spherical case surface.
Further, described drawing step, in forming process, needs after each drawing to observe the drawing state of part, need carry out smoothing wrinkle process, then carry out drawing next time if there is fold.
Beneficial effect of the present invention is: adopt titanium material, can effective anticorrosive oxidation, avoids the problem that steel cylinder shortens service life in specific environment, have employed acid solution and clean, and goes out the iron filings on top layer, makes it more attractive in appearance.Preparation method of the present invention not only significantly saves material, reduces the cost of ball valve core; And the ball valve core precision made, thickness, integrality can be guaranteed, the intensity of valve rod Connection Block and valve rod junction is improved.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described.
Drawing manufactures a technique for titanium material material ball valve core, comprises the following steps: select materials: select titanium material sheet material as blank, carry out Size calculation according to spool size, is then cut by blank according to the target size after calculating with cutting machine; Annealing: the plectane after cutting is placed in annealing furnace and carries out annealing in process, annealing furnace keeps temperature more than 550 ~ 600 DEG C, 15 ~ 30 minutes duration, then cools rapidly; Drawing: the blank after polishing is placed on mould; open clapper die spotting press; be warming up to 300 DEG C ~ 450 DEG C; carry out first time Hot drawing; above-mentioned annealing steps is carried out again for the first time after Hot drawing; again blank is placed in mould and carries out second time Hot drawing, blank after second heat drawing is carried out Hot drawing school shape for the third time and, until obtain regular spherical shell, carry out pressurize process when third time Hot drawing school shape.Described drawing step, in forming process, needs after each drawing to observe the drawing state of part, need carry out smoothing wrinkle process, then carry out drawing next time if there is fold.After obtaining spherical shell, open a vertical masonry joint backlash in the centre position of spherical case surface and extrude valve rod groove, or output valve rod groove at the centre position milling cutter of spherical case surface.Insert interior straight tube: in selecting, logical and external diameter is less than the titanium material pipe of spherical shell latus rectum, be cut to spherical shell latus rectum isometric, adopt straight tube in the tapered punch punching press expansion on punch press or stamping machine, interior straight tube and spherical shell are fixed together and form finished product spool; Polishing: carry out surface finish, by clean for sanding burr also polishing; Cleaning: the spool made is put into acid solution, keeps 15 minutes, finally take out and rinse.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
