Abstract
The invention discloses a kind of nut Sheet Metal Forming Technologies, the specific steps are as follows: wire rod enters mould, cuts wire rod, smart mould export, punch forming, blank ejection；The wire rod is imported into mold, the mold includes roughcast and smart mould, and the essence mould is fastened in the corase grinding, and the essence mould tail portion is fixed with top pillar；The wire rod is cut off by cutter, the smart mould is released from the roughcast, the essence mould rotation rotates clockwise 90 °, by formed punch and the smart mould pressure, so that punch forming, obtains blank, the blank is ejected out of smart mould by the top pillar, obtains finished product.It is formed by the above-mentioned means, the present invention can be realized fast ram while ensuring nut precision, obtains high-precision blank, be not necessarily to secondary operation, and method is simple, it is easy to operate, it is suitble to quickly production.
Description
Technical field
The present invention relates to nut preparation fields, more particularly to a kind of nut Sheet Metal Forming Technology.
Background technique
Punching press is that depended on pressure machine and mold apply external force to plate, band, tubing and profile etc., is allowed to generate plastic deformation
Or separation, thus the forming and machining method of the workpiece (stamping parts) of shape and size needed for obtaining.Punching press and forging belong to plasticity
It processes (or pressure processing), 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, iron core silicon-steel sheet of electric appliance etc. 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.
Currently, 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, preparation process is complex.The present invention is by innovative design, by screw channel punching press and nut head
Punching press is combined into one, one-pass molding, to greatly improve production efficiency, reduces production cost, while also ensuring that the essence of nut
Degree and intensity are unaffected.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of nut Sheet Metal Forming Technology, can be realized is ensuring nut precision
While fast ram form, obtain high-precision blank, be not necessarily to secondary operation, and method is simple, easy to operate, is suitble to quick
Production, by innovative design, screw channel punching press and nut head punching press is combined into one, one-pass molding, to greatly improve production
Efficiency reduces production cost, while also ensuring that the precision of nut and intensity are unaffected.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of nut Sheet Metal Forming Technology is provided, is had
Steps are as follows for body: wire rod enters mould, cuts wire rod, smart mould export, punch forming, blank ejection；The wire rod is imported into mold, institute
Stating mold includes roughcast and smart mould, and the essence mould is fastened in the corase grinding；The wire rod is cut off by cutter, it will be described
Smart mould is released from the roughcast, and the essence mould rotation rotates clockwise 90 °, by formed punch and the smart mould pressure, to rush
It is molded, blank is obtained, the blank is ejected out of smart mould by top pillar, obtains finished product.
In a preferred embodiment of the present invention, the formed punch is equipped with the prominent mould of cross.
In a preferred embodiment of the present invention, the smart mould tail portion is equipped with top pillar.
It forms, obtains the beneficial effects of the present invention are: the present invention can be realized fast ram while ensuring nut precision
High-precision blank, be not necessarily to secondary operation, and method is simple, easy to operate, is suitble to quickly production, will by innovative design
Screw channel punching press and nut head punching press are combined into one, one-pass molding, to greatly improve production efficiency, reduce production cost, together
When also ensure that the precision of nut and intensity are unaffected.
Specific embodiment
The preferred embodiments of the present invention will be 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 so as to make a clearer definition of the protection scope of the present invention.
The embodiment of the present invention includes:
A kind of nut Sheet Metal Forming Technology, the specific steps are as follows: wire rod enters mould, cuts wire rod, smart mould export, punch forming, base
Part ejection；The wire rod is imported into mold, the mold includes roughcast and smart mould, and the essence mould is fastened in the corase grinding；
The wire rod is cut off by cutter, the smart mould is released from the roughcast, smart mould leading portion has one section of 1cm length at this time
Wire rod it is exposed, the smart mould rotation is rotated clockwise 90 °, by formed punch and the smart mould pressure, punch shape is nut
Shape needed for head, ram impacts essence mould, the exposed wire rod of leading portion are squeezed deformation, are crowded with nut head spaces set by formed punch
It is interior, so that punch forming, obtains blank, the blank is ejected out of smart mould by top pillar, obtains finished product.
It further illustrates, the formed punch is equipped with the prominent mould of cross.By punching press, because being equipped with the prominent mould of cross, punching
The shape of cross recess is just directly snapped out on molded nut head, so that reaching a punching press obtains the effect for completing nut head
Fruit.
Further illustrate, the essence mould tail portion is equipped with top pillar.Top pillar is fixed on smart mould tail initially by galvanomagnetic-effect
Portion, after to be punched, power-off makes galvanomagnetic-effect fail, to keep top pillar movable, by pushing top pillar, by blank from essence
Ejection in mould, to obtain finished product.
The present invention can be realized fast ram while ensuring nut precision and form, and obtains high-precision blank, is not necessarily to
Secondary operation, and method is simple, it is easy to operate, it is suitble to quickly production, by innovative design, by screw channel punching press and nut head punching press
Be combined into one, one-pass molding, to greatly improve production efficiency, reduce production cost, at the same also ensure that nut precision and
Intensity is unaffected.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
