Abstract
The utility model relates to a kind of for the stamping forming mould of ball valve core, belong to valve manufacture field, comprise upper die and lower die, patrix is provided with an episphere chamber, counterdie is provided with a lower semisphere chamber, and after upper die and lower die matched moulds, episphere chamber and lower semisphere chamber form a complete spherical cavity, are provided with locating rack in spherical cavity., low cost of manufacture simple by this mould structure and the high advantage of working (machining) efficiency, and the adjustable of its fixed part arranges the applicability improving this mould, reduces the manufacturing cost because different product needs different mould to cause.
Description
Technical field
The utility model belongs to valve manufacture field, relates to a kind of mould, particularly a kind of for the stamping forming mould of ball valve core.
Background technology
Valve makes the middle control assembly of fluid delivery system, ball-valve structure wherein generally comprises valve body and spherical spool, and spool comprises outer spherical shell and interior straight tube composition, outer spherical shell and interior straight tube are fixedly connected by welding, this ball valve has the advantage of water proofing property and good airproof performance relative to the ball valve core that traditional foundry casting makes, but connect because add wire bond by circumferential weld between the end of spherical shell and the sidewall of interior straight tube, interior straight tube need thicken and lengthen in case puncture workpiece when welding, in turning inner hole and both ends of the surface after welding, waste material and process time longer, solder joint sealing surface place just in time simultaneously, machine rear discovery rosin joint, pore, filler deficiency forms the deficiencies such as depression.Present technique have also been made improvement for above-mentioned deficiency, carries out cold heading technique and connects, but it does not have ready-made mould and causes producing efficiently by batch.Therefore be badly in need of now a kind of mfg. moulding die of the spool for cold heading technique.
Utility model content
The purpose of this utility model is overcome the deficiency existed in background technology, the purpose of this utility model be propose a kind of efficient, long service life for the stamping forming mould of ball valve core.
For achieving the above object, the utility model adopts following scheme: a kind of for the stamping forming mould of ball valve core, comprise patrix 100 and counterdie 200, patrix 100 is provided with an episphere chamber, counterdie 200 is provided with a lower semisphere chamber, and after patrix 100 and counterdie 200 matched moulds, episphere chamber and lower semisphere chamber form a complete spherical cavity, are provided with locating rack in spherical cavity.
To above-mentioned technical scheme, do further design: in described spherical cavity, be provided with a fixed head 600, and described locating rack 300 is placed in spherical cavity by fixed head 600.
To above-mentioned technical scheme, do further design: described locating rack is divided into fixed part 302 and tensioned portion 301, and locating rack is fixed in spherical cavity by fixed part 302.
To above-mentioned technical scheme, do further design: described fixed part 302 is waveform, and fixed part 302 is connected with fixed head 600 is adjustable by screw thread.
To above-mentioned technical scheme, do further design: described tensioned portion 301 with by one, there is flexible loop 303 between fixed part 302 and be connected.
Beneficial effect is:, low cost of manufacture simple by this mould structure and the high advantage of working (machining) efficiency, and the adjustable of its fixed part arranges the applicability improving this mould, reduces the manufacturing cost because different product needs different mould to cause.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model mould.
Fig. 2 is the combination schematic diagram of the utility model mould.
Fig. 3 is the fixing schematic diagram of inner metal tube in the utility model.
Annotate in figure: 100-patrix, 200-counterdie, 300-locating rack, 301-tensioned portion, 302-fixed part, 303-loop, the outer metal tube of 400-, 500-inner metal tube, 600-fixed head.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Referring to figs. 1 to Fig. 3, a kind of for the stamping forming mould of ball valve core, comprise patrix 100 and counterdie 200, patrix 100 is provided with an episphere chamber, counterdie 200 is provided with a lower semisphere chamber, and after patrix 100 and counterdie 200 matched moulds, episphere chamber and lower semisphere chamber form a complete spherical cavity, are provided with locating rack in spherical cavity.In operation, by workpiece being divided into outer metal circular tube and inner metal tube 500, interior metal circular tube is fixed in spherical cavity by locating rack 300, outer metal tube 400 is placed in the edge in patrix 100 episphere chamber, and carry out interference fits with episphere chamber, make patrix 100 relative with counterdie 200 close again, now make outer metal circular tube ready-made spherical by the extruding of patrix 100 and counterdie 200, and contact with interior metal circular tube and coordinate.Meanwhile, in the design, in order to ensure to improve its operating efficiency and stability, described locating rack 300 is divided into fixed part 302 and tensioned portion 301, and locating rack 300 is fixed in spherical cavity by fixed part 302.
A fixed head 600 is provided with in described spherical cavity, and described locating rack 300 is placed in spherical cavity by fixed head 600, and fixed part 302 is connected with fixed head 600 is adjustable by screw thread, specifically, screw can be offered on fixed head 600, fixed part 302 arranges screw thread, so just according to the product of different model, the length of fixed part can be regulated by screw thread.Simple to operate, product applicability is wide, arranges fixed part 302 for waveform simultaneously, improved the tensile force of its tensioned portion by waveform, and described tensioned portion 301 with by one, there is flexible loop 303 between fixed part 302 and be connected.So produce tensile force F by the elasticity of its loop 303 and make inner stable being fixed on fixed part 302 of metal circular tube., low cost of manufacture simple by this mould structure and the high advantage of working (machining) efficiency.
The foregoing is only preferred embodiment of the present utility model, is not restriction with the present embodiment, all make within spirit of the present utility model and principle any amendment, equivalent to replace or improvement etc., all should be included within protection domain of the present utility model.
