Description
Technical field
The utility model relates to high-intensity fasteners and manufactures field, is specifically related to a kind of nut punch-forming mold.
Background technology
Securing member is fastenedly connected with and applies class machine components very widely.Various machinery, equipment, vehicle, boats and ships,
railway,
bridge, building, structure, instrument,
instrument, above instrument and articles for use etc., securing member miscellaneous can be seen.Its feature is that description is various, and performance purposes is different, and standardization, seriation, unitized kind of degree are also high.Therefore also there is people that one class securing member of obtained official standard is called standard fasteners, or referred to as
standard component.Securing member is most widely used mechanical basic part.Along with China adds calendar year 2001
wTOand step into the ranks of international trade big country.China's fastener products exports to countries in the world in a large number, the fastener products of countries in the world also constantly pours in Chinese market.Securing member, as one of larger product of China's import & export quantity, realizes in line with international standards, and to promotion, Chinese securing member enterprise goes to the world, and promotes that securing member enterprise participates in international cooperation and competition comprehensively, all tool important realistic meaning and strategic importances.Nut is generally with internal thread hole, and shape generally manifests as flat hexagonal cylindricality, also has in flat square column type or oblate cylindricality, fitted bolt, stud or machine screw, for being fastenedly connected two parts, makes it to become an entirety.
Being generally at the molding mode of nut adopts diel to be out of shape by the ram extrusion of drift, completes the endoporus of nut and the shaping of outline.In existing diel, the structure of drift is punching cylinder and forms in hexagonal crimp post, the endoporus of nut is completed by the punching press of punching cylinder, the end face of crimp post then by extruding nut makes nut material generation crimp, finally complete the shaping of nut, but, this kind of mode diel is adopted to there is following several respects defect: (1) adopts the punching press of punching cylinder to complete the shaping of endoporus, due to punching cylinder, to be cylinder larger to the frictional force of drift when punching press, affecting the larger stamping press of needs by drift cylindrical cross-section just can make material be swept away, therefore the liquidate damage of hole circle post and forcing press of punching course is larger, greatly reduce the service life of drift, (2) outline of nut is shaping forces material generation crimp to complete by crimp post extruding nut end face, but, the pressure requirements of this kind of mode to forcing press is too high, easy damage forcing press, and the bad control of the crimp of material all directions, cause shaping complete after nut outward appearance not full, aesthetic property is poor, (3) shear stress that is subject to of the one time punching molded material of punching cylinder is comparatively large, is unfavorable for follow-up screw thread process.
Application number is in the Chinese patent of " 201220302058.8 ", discloses the utility model patent that name is called " hot stamping mould for nut ", and its technical scheme is as follows: comprise die shank, cope match-plate pattern, upper die plate, upper mounted plate, rubber blanket, de-backing strap plate, with the upper mold core fixed head of upper mold core, lower bolster, counterdie backing plate, bottom plate, with the lower die-sleeve of lower mold core, patrix core ribbon hexagonal hole and sliding fit upper male mould in hole, upper male mould upper end is through de-backing strap plate, be arranged in upper mounted plate after rubber blanket with the first hole of axial limiting upper male mould, upper end and the first hole sliding fit and end face with through die shank, the lower surface of the knock-pin that upper die plate enters in the first hole offsets, knock-pin and die shank, for the second hole sliding fit that knock-pin passes in upper die plate, tape guide hole, upper male mould lower end and the first forming ends, counterdie core ribbon second forming ends, passes the second forming ends is outer and lower mold core is coaxial counterdie positioning guide column by locating dowel, with pilot hole sliding fit and the lead that diameter is less than locating dowel form.Although this mould can produce interior attaching nut, but, the mode of its nut appearance profile is the end face generation crimp of employing first forming ends and the second forming ends pressing nut, carry out the shaping of nut outline, the pressure requirements of this kind of mode to forcing press is too high, easily damages forcing press, and the bad control of the crimp of material all directions, cause shaping complete after nut outward appearance not full, aesthetic property is poor.
