Description
Technical field
The utility model relates to a kind of spring 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 spring reset heading die relative to manufacturing cost.
The technical solution of the utility model is: a kind of spring reset heading die, comprise die shank, cope match-plate pattern, fixed head one, packing ring, spring, centring ring, 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, centring ring, spring 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; Fixed head one by one side is processed with blind hole and locates for spring, and the hole of using with stove bolt is concentric; The small end of centring ring is for spring location, and band tapering.
Spring reset heading die described in the utility model is simple in structure, easy to use, design and low cost of manufacture.
Brief description of the drawings
Fig. 1 is the utility model spring reset heading die axonometric drawing, and Fig. 2 is centring ring axonometric drawing (magnification ratio on Fig. 1 basis).
1. die shanks in Fig. 1,2. cope match-plate pattern, 3. fixed head one, 4. packing ring, 5. spring, 6. centring ring, 7. stove bolt, 8. king-bolt, 9. lower bolster, 10. fixed head two, 11. fixture block one, 12. fixture block two, 13. nuts, 14. blanks, 15. headings.
Detailed description of the invention
As shown in Figure 1, described spring reset heading die, comprise die shank 1, cope match-plate pattern 2, fixed head 1, packing ring 4, spring 5, centring ring 6, stove bolt 7, king-bolt 8, lower bolster 9, fixed head 2 10, fixture block 1, fixture block 2 12, nut 13, blank 14, heading 15, die shank 1 one end is processed with screw thread and connects with cope match-plate pattern 2, and heading 15 is welded on cope match-plate pattern 2; Fixed head 1 and fixed head 2 10 pass through screw attachment with lower bolster 9, fixture block 1 is screwed on fixed head 2 10, packing ring 4 is placed on king-bolt 9, king-bolt 9 connects with fixed head 2 10 with fixed head 1, and it is fastening to add nut 13 in the each side of two plates, centring ring 6, spring 5 are placed on stove bolt 7 successively, and stove bolt 7 connected fixed head 1 and connects with fixture block 2 12, and blank 14 is placed in fixture block 1 and fixture block 2 12.
In described spring reset heading die, fixed head 2 10 upside middle parts are processed with breach, are convenient to heading 15 and insert; Fixed head one 3 one sides are processed with blind hole and locate for spring 5, and concentric with the hole of stove bolt 7 use.
In described spring reset heading die, the small end of centring ring 6 is located for spring 5, and band tapering.
In described spring reset heading die, in advance blank 14 is wanted to one end heating of jumping-up, after heating, place in fixture block 1 and fixture block 2 12, when heading 15 moves downward under stamping machine effect, first insert in the groove of fixed head 2 10, with advancing left by fixture block 2 12, fixture block 1 is clamped with the blank 14 in fixture block 2 12, and blank 14 head jumping-up moulding simultaneously, after heading 15 rollbacks, fixture block 2 12 resets under the effect of spring 5, workpiece is taken out with clip.
