Description
Technical field
The present invention relates to a kind of hot stamping die, relate to a kind of half-finished hot stamping die of nut that is used to produce or rather.
Background technology
Nut is widely used in industry, and hex nut is divided into thick hexagonnut and hexagon thin nut by thickness.General technical process of producing hex nut is divided into: 1, use the nut Cold header raw material to be processed into the semi-finished product that do not have internal thread through blank-pressure ball-pressure hexagonal-punching; 2, through the continuous tapping of tapping machine semi-finished product are carried out internal thread machining, heat-treat with surface treatment and form finished product.Existing shortcoming of producing the half-finished technology existence of nut is: when producing high nut; Tonnage to Cold header has higher requirement; Above-mentioned technical process is complicated, consuming time many, and waste of material is big during punching, not crystallization again in the cold pier production process; Be prone to the high nut insufficient strength and influence service life, must guarantee the intensity of high nut through heat treatment process.
Summary of the invention
The technical problem that the present invention will solve is, a kind of hot stamping die is provided, and utilizes this hot stamping die, can make the production technology of nut simple, consuming time less, save material and can increase the intensity of nut.
Technical solution of the present invention is; A kind of nut hot stamping die with following structure is provided; Comprise die shank, top mold frame, upper die plate, fixed head, elastomer, the stripper plate and the following mould bases that is fixedly connected sequentially from the bottom up, counterdie backing plate, counterdie fixed head, backing plate and the recessed template that are fixedly connected from top to bottom; Described die shank lower end is fixed on the top mold frame; Be fixed with the last punch of hollow in the shoulder hole that described stripper plate, elastomer and fixed head three constitute; Described recessed template and backing plate constitute shoulder hole in be provided with core rod and the following dynamic model that is slidingly matched, the cross section on the top of described hole of going up punch, recessed template and following dynamic model is hexagon, the described bottom surface of dynamic model of descending is provided with ejecting mechanism.
Described down dynamic model is slidingly matched and is meant that the described inner surface of dynamic model down cooperates with core slide, the outer surface of described following dynamic model and recessed template and backing plate formation shoulder hole be slidingly matched.
The described cross section of the bottom of dynamic model down is a hexagon or circular, the hole that the lower shape of dynamic model matches under the Kong Weiyu on the described backing plate.
After adopting above structure, nut hot stamping die of the present invention compared with prior art has the following advantages:
Because what nut hot stamping die of the present invention adopted is a kind of hot stamping die; The raw material that adopt are seamless steel pipes, and with putting into mould after the heating behind the seamless steel pipe blank, matched moulds carries out punching press; Die sinking; Discharging is accomplished for the pressure ball and the pressure hexagonal structure of nut in the lump, and technical process is simple, consuming time few; The raw material that adopt are seamless steel pipes, need not carry out punching, save the production time and save material; What the present invention adopted is a kind of hot stamping die, carries out drop stamping, can make metal material body intercrystalline, and the density of metal material and intensity are increased.
As a kind of improvement of the present invention; Described top mold frame, upper die plate, fixed head, elastomer and stripper plate fixed connection are meant and are provided with the combination double-screw bolt that can slide up and down between stripper plate, elastomer and the fixed head, be fixedly connected by securing member between described top mold frame, upper die plate, the fixed head.Upwards sliding when elastomer compress in described combination double-screw bolt upper end, when elastomer recovers, to lower slider, and can not drop out fixed head, guarantees that elastomer can be fixedly connected with fixed head with stripper plate all the time, and difficult quilt fractureed, and service life is longer.
As a kind of improvement of the present invention, the profile of described top mold frame, upper die plate, fixed head, stripper plate, recessed template, backing plate, counterdie fixed head, counterdie backing plate and following mould bases is cylindrical.Cylindrical is zhou duicheng tuxing, is difficult for sideslip during punching press, and the product axial symmetry that punching press is come out is good.
