Embodiment Construction
[0009] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0010] Embodiments of the invention include:
[0011] A nut stamping process, the specific steps are as follows: wire rod into the mold, cut the wire rod, fine mold export, stamping forming, blank ejection; the wire rod is introduced into a mold, the mold includes a rough mold and a fine mold, the The fine mold is engaged in the rough grinding; the wire is cut off by a cutter, and the fine mold is pushed out from the rough mold. At this time, a section of 1 cm long wire will be exposed in the front section of the fine mold, and the The fine mold rotates 90° clockwise, and the punch hits the fine mold. The shape of the punch is the shape required by the nut head. In the space of the nut head pro...

The invention discloses a nut stamping technology. The nut stamping technology includes the following specific steps of wire-material mold entering, wire-material shearing, accurate mold leading, stamping forming and blank ejection; a wire material is led into a mold, the mold comprises a rough mold and an accurate mold, the accurate mold is clamped into the rough mold, and a top column is fixed to the tail of the accurate mold; the wire material is cut off through a cutting knife, the accurate mold is pushed out of the rough mold, and the accurate mold clockwise rotates 90 degrees; percussion pressing is carried out through a punch and the accurate mold, stamping forming is carried out accordingly, and a blank is obtained; the blank is ejected out of the accurate mold through the top column, and a finished product is obtained. By means of the nut stamping technology in the mode, it can be achieved that rapid stamping forming is achieved while the accuracy of the nut is guaranteed, and the high-accuracy blank is obtained; secondary processing is not required; the method is simple, operation is convenient, and the nut stamping technology is suitable for rapid production.
Description
technical field [0001] The invention relates to the field of nut preparation, in particular to a nut stamping process. Background technique [0002] Stamping is a forming processing method that applies external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation to obtain workpieces (stamping parts) of required shape and size. Stamping and forging belong to plastic processing (or pressure processing) and are collectively called forging. The body, chassis, fuel tank, radiator fins of the car, the steam drum of the boiler, the shell of the container, the iron core silicon steel sheet of the motor and electrical appliances, etc. are all stamped. There are also a large number of stamping parts in products such as instruments and meters, household appliances, bicycles, office machinery, and living utensils. [0003] At present, the stamping process of nuts generally needs to stamp out the nut head, and then perform seconda...
