Description
Technical field
The present invention relates to nut preparation field, more particularly to a kind of nut Sheet Metal Forming Technology.
Background technology
Punching press is that depended on pressure machine and mould apply external force to sheet material, band, tubing and section bar etc., is allowed to produce plastic deformation
Or separation, so as to obtain the workpiece of required shape and size（Stamping parts）Forming and machining method.Punching press and forging belong to plasticity together
Processing（Or pressure processing）, it is collectively referred to as forging and pressing.Vehicle body, chassis, fuel tank, the radiator fin of automobile, the drum of boiler, the shell of container
Body, motor, the iron core silicon-steel sheet etc. of electrical equipment are all punch process.Instrument and meter, household electrical appliance, bicycle, office machinery, life
In the products such as vessel living, also there are a large amount of stamping parts.
At present, the Sheet Metal Forming Technology of nut, which is typically necessary, stamps out nut head, two times punch is then carried out, on nut head
Stamp out screw channel of different shapes, its preparation technology is complex.The present invention is by innovative design, by screw channel punching press and nut head
Punching press is combined into one, one-shot forming, so as to greatly improve production efficiency, reduces production cost, while also ensure that the essence of nut
Degree and intensity are unaffected.
The content of the invention
The present invention solves the technical problem of a kind of nut Sheet Metal Forming Technology is provided, can realize is ensuring nut precision
While fast ram be molded, obtain high-precision blank, without secondary operation, and method is simple, easy to operate, is adapted to quick
Production, by innovative design, screw channel punching press and nut head punching press is combined into one, one-shot forming, so as to greatly improve production
Efficiency, production cost is reduced, while also ensure that the precision of nut and intensity are unaffected.
In order to solve the above technical problems, one aspect of the present invention is：A kind of nut Sheet Metal Forming Technology is provided, had
Body step is as follows：Wire rod enters mould, cuts wire rod, the export of smart mould, punch forming, blank ejection；The wire rod is imported into mould, institute
State mould and include roughcast and smart mould, the smart mould is fastened in the corase grind；The wire rod is cut off by cutting knife, by described in
Smart mould is released from the roughcast, and the smart mould rotation turns clockwise 90 °, by drift and the smart mould pressure, so as to rush
It is molded, blank is obtained, the blank is ejected out of smart mould by fore-set, obtains finished product.
In a preferred embodiment of the present invention, the drift is provided with the prominent mould of cross.
In a preferred embodiment of the present invention, the smart mould afterbody is provided with fore-set.
The beneficial effects of the invention are as follows：The present invention can realize that fast ram is molded while nut precision is ensured, is obtained
High-precision blank is obtained, without secondary operation, and method is simple, easy to operate, is adapted to quick production, will by innovative design
Screw channel punching press and nut head punching press are combined into one, one-shot forming, so as to greatly improve production efficiency, reduce production cost, together
When also ensure that the precision of nut and intensity are unaffected.
Embodiment
Presently preferred embodiments of the present invention is described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly defined so as to be made to protection scope of the present invention.
The embodiment of the present invention includes：
A kind of nut Sheet Metal Forming Technology, is comprised the following steps that：Wire rod enters mould, cuts wire rod, the export of smart mould, punch forming, blank top
Go out；The wire rod is imported into mould, the mould includes roughcast and smart mould, and the smart mould is fastened in the corase grind；Pass through
Cutting knife cuts off the wire rod, and the smart mould is released from the roughcast, and now smart mould leading portion has the line of one section of 1cm length
Material is exposed, the smart mould rotation is turned clockwise 90 °, by drift and the smart mould pressure, punch shape is nut head institute
The shape needed, ram impacts essence mould, the exposed wire rod of leading portion are squeezed deformation, are crowded with the nut head space set by drift,
So as to punch forming, blank is obtained, the blank is ejected out of smart mould by fore-set, obtains finished product.
Further illustrate, the drift is provided with the prominent mould of cross.By punching press, because being dashed forward mould provided with cross, punching
The shape of cross recess is just directly snapped out on molded nut head, so as to reach the effect that a punching press obtains completion nut head
Fruit.
Further illustrate, the smart mould afterbody is provided with fore-set.Fore-set is fixed on smart mould tail initially by galvanomagnetic-effect
Portion, after end to be punched, power-off makes galvanomagnetic-effect fail so that fore-set can activity, by pushing fore-set, by blank from essence
Ejected in mould, so as to obtain finished product.
The present invention can realize that fast ram is molded while nut precision is ensured, obtains high-precision blank, without
Secondary operation, and method is simple, it is easy to operate, it is adapted to quick production, by innovative design, by screw channel punching press and nut head punching press
Be combined into one, one-shot forming, so as to greatly improve production efficiency, reduce production cost, at the same also ensure that nut precision and
Intensity is unaffected.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
Domain, it is included within the scope of the present invention.
