Description
Technical field
The utility model relates to field of mechanical technique, is specifically related to a kind of screw nut die.
Background technology
In nut process, there is three productions technique, cold-heading and hot upsetting, when more special, also have mach, be the slowest one of efficiency, have no alternative but just can select.Cold-heading, usually first wire rod is chosen, after overpickling cold-drawn, one title of wire rod is connected on the material loading place of cold headers, the hexagonal blank of corresponding size can be got according to the mould in cold headers, middle porose, form is the same with general hex nut is exactly do not have tapping, old-fashioned cold headers can not one-shot forming, accomplish fluently hexagonal blank, then must be poured in the funnel on tooth machining unit and carry out tapping, there are the words of requirement, must need to heat-treat and surface treatment, be exactly the hardness of adjusting nut and the antirust treatment on surface, present cold headers are once shaping, exactly tooth machining unit and cold headers are combined together efficiency more hurry up, cold-heading molding is that efficiency is the fastest, also be the production technology that cost is minimum.Generally larger specification just can select hot upsetting, and material is generally round steel, without cold-drawn and pickling, first blanking, beating through punch press upsetting, blank is the same with cold-heading, be exactly surperficial crude, and then tapping, there is particular requirement, chamfering can be carried out in the two sides of nut, just completing through heat treatment, surface treatment, clavate material is cut into a section by machined exactly through sawing machine, just substantially completed in tapping by jewel hole machine drill eye, below be exactly packed.
At present, in nut process, generally first forge into rectangle, and then the manufacturing process by sawing or grinding, manufactured required shape.Such manufacture, not only production efficiency is low, and the end properties produced is poor.In order to improve production efficiency and the end properties of nut, devise the screw nut die needing to coordinate drift to use, but in process, there is the problem of deviations in drift, thus cause the quality of nut finished product unstable.For solving the problem, the utility model provides a kind of structure simple, improves productivity ratio, ensure that product quality, simplify technique, effectively control cost, reduce the screw nut die of personnel labor intensity.
Utility model content
The utility model provides a kind of screw nut die, and structure is simple, and improve productivity ratio, ensure that product quality, simplify technique, effectively control cost, reduce personnel labor intensity, in order to solve technique scheme, the utility model adopts following technical scheme:
A kind of screw nut die, comprise die ontology, the front and back of described die ontology are respectively provided with an one number service hole, the top of described die ontology is provided with a cylinder boss, the below of described die ontology is provided with No. two round boss, a described cylinder boss be each side provided with a fixing hole, the inwall of a described cylinder boss is to protruding formation hexagonal draw-in groove inside it, the bottom centre of described draw-in groove is provided with No. two through holes, and described No. two through holes run through described die ontology.
A kind of screw nut die that the utility model provides, the diameter that can be set to described No. two round boss is further identical with the front and back width of described die ontology, and the external diameter of a described cylinder boss is less than the radius of described No. two round boss.
A kind of screw nut die that the utility model provides, can be set to the upper surface of a described cylinder boss and described draw-in groove further not at grade, described draw-in groove extends downwardly into the top of described No. two round boss.
A kind of screw nut die that the utility model provides, can be set to place, described one number service hole straight line further through the center of circle of described No. two through holes.
A kind of screw nut die that the utility model provides, the two ends, left and right that can be set to described die ontology are further set to circular arc type.
Advantage of the present utility model and beneficial effect are: to sum up, a kind of screw nut die that the utility model provides, and structure is simple, improves productivity ratio, ensure that product quality, simplify technique, effectively control cost, reduce personnel labor intensity.Wherein, the diameter of described No. two round boss is identical with the front and back width of described die ontology, the external diameter of a described cylinder boss is less than the radius of described No. two round boss, guarantees the steady of working environment, avoids the quality reducing product because vibrations produce deviation; The upper surface of a described cylinder boss and described draw-in groove are not at grade, described draw-in groove extends downwardly into the top of described No. two round boss, guarantee when converted products, product can be stabilized in described draw-in groove, avoid product under the effect of diel, depart from described die ontology, produce potential safety hazard; Place, described one number service hole straight line, through the center of circle of described No. two through holes, ensures there is good aeration when converted products and do not affect product quality; The two ends, left and right of described die ontology are set to circular arc type, and avoiding has the danger such as scuffing when contacting described mould.
