Abstract
The invention relates to a spring resetting upsetting die and belongs to the field of punching dies. The die comprises a die handle, an upper die plate, a first fixing plate, gaskets, springs, positioning rings, small bolts, big bolts, a lower die plate, a second fixing plate, a first clamping block, a second clamping block, nuts, a blank and an upsetting head. Threads are machined at one end of the die handle to make the die handle be in linkage with the upper die plate, and the upsetting head is welded to the upper die plate. The first fixing plate and the second fixing plate are in linkage through screws, the first clamping block is fixed to the second fixing plate through screws, the gaskets are arranged on the big bolts, and the big bolts are in linkage with the first fixing plate and the second fixing plate. The nuts are additionally arranged on the both sides of the two plates for fastening, and the positioning rings and the springs are sequentially placed on the small bolts. The small bolts penetrate through the first fixing plate to be in linkage with the second clamping block, and the blank is placed between the first clamping block and the second clamping block. According to the technical scheme, the die is simple in structure, convenient to use and low in designing and manufacturing cost.
Description
Technical field
The present invention relates to a kind of spring reset heading die, belong to diel field, be 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 invention provides that a kind of structure is relatively simple, design low spring reset heading die relative to manufacturing cost.
Technical scheme of the present invention 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 each side adds fastening nuts at the two poles of the earth, 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 present invention is simple in structure, easy to use, design and low cost of manufacture.
Brief description of the drawings
Fig. 1 unabridged version invention spring reset heading die axonometric drawing, 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 bolts, 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 pole 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 add lower jagged, 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.
