Description

A kind of rubber formula reset heading die

Technical field

The utility model relates to a kind of rubber formula reset heading die, belongs to diel field, is mainly used in the moulding of metal head jumping-up.

Background technology

The part of conventional class nail in life, due to nail main body be cylindric and diameter little, on special machine, adopt steel wire by its cut-out in by its head upsetting squeeze moulding; Processing technology is by milling round steel heating, drawing, blanking, head cold-heading molding, threading, heat treatment etc. as the larger screw of diameter, wherein head cold-heading molding is most important operation, cold-heading molding is generally on extruder, need to design special mould, sometimes upsetting squeeze moulding several times, in case a large generation cracking of Extrusion Forging Deformation amount, this just need to design many molds.No matter be nail or screw, be not that equipment investment is exactly greatly to want design specialized mould, and the main body of part is all cylindric, and the batch great talent of generation is worthwhile.In life, its main body of some part is not cylindric, is prism-shaped or its cross section is ellipticity, and while not being too many in batches, adopting above-mentioned manufacture method to be linked to be this and all receive to return.The present invention be directed to head moulding does not have particular/special requirement, as long as jumping-up just can.

Summary of the invention

The problem existing for above-mentioned prior art, the utility model provides that a kind of structure is relatively simple, design low rubber formula reset heading die relative to manufacturing cost.

The technical solution of the utility model is: a kind of rubber formula reset heading die, comprise die shank, cope match-plate pattern, fixed head one, packing ring, rubber, backing plate, stove bolt, king-bolt, lower bolster, fixed head two, fixture block one, fixture block two, nut, blank, heading, die shank one end is processed with screw thread and connects with cope match-plate pattern, and heading is welded on cope match-plate pattern; Fixed head one and fixed head two pass through screw attachment with lower bolster, fixture block one is screwed on fixed head two, packing ring is placed on king-bolt, king-bolt connects with fixed head two with fixed head one, and add fastening nuts in the each side of two plates, backing plate, rubber are placed on stove bolt successively, and stove bolt connected fixed head one and connects with fixture block two, and blank is placed in fixture block one and fixture block two.

Described fixed head two upside middle parts are processed with breach, are convenient to heading and insert; Rubber has elasticity, is cylindric.

Rubber formula reset heading die described in the utility model is simple in structure, easy to use, design and low cost of manufacture.
