Abstract
The utility model relates to a hexagonal bolt hexagonal head precise shrinkage and thread blank diameter-shrinkage diameter die which includes a lower die seat 6, a hexagonal head precise shrinkage die 2 which is arranged in the lower die seat from top to bottom, a precise shrinkage die rear pad 3, a thread blank diameter-shrinkage diameter die front pad 4, a thread blank diameter-shrinkage die 5, a thread blank diameter-shrinkage die rear pad 7, a die ejector rod 8, a die ejector rod sleeve ring 10, a lower seat pad 9, a rear ejector rod 12, a rear ejector rod sleeve ring 11, a rear ejector rod guide sleeve 14, and an upper parallel cap 1 and a lower parallel cap 13; the upper parallel cap is pivotally arranged at a top end of the lower die seat; the lower die seat pad is pivotally arranged at a lower end of the lower die seat; the die ejector rod sleeve ring and the rear ejector rod sleeve ring are arranged in the lower die seat pad; a lower end of the die ejector rod is inserted into the die ejector sleeve ring; an upper end of the die ejector rod is arranged in the thread blank diameter-shrinkage die rear pad hole; the rear ejector rod guide sleeve is pivotally arranged on a lower part of the lower die seat; the lower parallel is pivotally arranged on the rear ejector rod guide sleeve; two ends of the rear ejector rod are inserted into the rear ejector rod guide sleeve and the rear ejector rod sleeve ring. The utility model makes the two working procedures of hexagonal head precise shrinkage and thread blank diameter-shrinkage of the bolt be finished at one time.
Description
Technical field:
The utility model relates to a kind of mould.Particularly relate to the final minification of a kind of hex bolts turret head, thread billet dia necking die tool.
Background technology:
The final minification of present existing hex bolts turret head, thread billet dia necking die tool generally adopt two molds.One the cover for turret head final minification mould, another set of be the thread billet dia necking die tool.Need to adopt two procedures just can finish the turret head final minification and the thread billet dia undergauge of hex bolts.So not only processing cost is higher, and production efficiency is low, and turret head and thread billet dia position of related features also can not get guaranteeing.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of can be with the turret head final minification of bolt and the final minification of the one step completed hex bolts turret head of thread billet dia undergauge two procedures, thread billet dia necking die tool.
The purpose of this utility model is achieved in that the final minification of a kind of hex bolts turret head, the thread billet dia necking die tool, it comprises die shoe, turret head final minification mould, fill up behind the final minification mould, the thread billet dia necking die foremast, thread billet dia necking die, fill up behind the thread billet dia necking die, the mould push rod, mould push rod lasso, the counterdie seat cushion, back push rod, back push rod lasso, back push rod guide pin bushing and on, following also cap, turret head final minification mould, fill up behind the final minification mould, the thread billet dia necking die foremast, fill up in the die shoe of packing into successively from top to bottom behind thread billet dia necking die and the thread billet dia necking die, going up also, cap is spun on the die shoe top, the counterdie seat cushion is spun on the die shoe lower end, mould push rod lasso and back push rod lasso place in the counterdie seat cushion, mould push rod lower end is inserted in the mould push rod lasso, and fill up in the centre bore after being inserted in thread billet dia necking die the upper end.Back push rod guide pin bushing is spun on counterdie seat cushion lower central, and also cap is spun on the push rod guide pin bushing of back down, and back push rod is inserted in the push rod guide pin bushing of back, and its front end is inserted in the push rod lasso of back.
During operation, the bar of the red rammer blank hex bolts that will be finished by last process is deployed in the die cavity of turret head final minification mould, and head is put the upper surface of turret head final minification mould, by punch die positive punching press downwards, make turret head enter turret head final minification mould, bar portion enters thread billet dia necking die simultaneously.So just can once finish the turret head final minification and the thread billet dia undergauge of hex bolts.Therefore not only processing cost is lower for the utility model, and production efficiency is higher, and the turret head of hex bolts and thread billet dia position of related features also are guaranteed.
Description of drawings:
Fig. 1 is a general structure schematic diagram of the present utility model.
The specific embodiment:
As Fig. 1, the utility model is the final minification of a kind of hex bolts turret head, thread billet dia necking die tool.Mainly by fill up 3 behind die shoe 6, turret head final minification mould 2, the final minification mould, fill up 7 behind the thread billet dia necking die foremast 4, thread billet dia necking die 5, thread billet dia necking die, mould push rod 8, mould push rod lasso 10, counterdie seat cushion 9, back push rod 12, back push rod lasso 11, back push rod guide pin bushing 14 and upper and lower and cap 1,13 form.Fill up 3 behind turret head final minification mould 2, the final minification mould, pad 7 is packed in the die shoe 6 from top to bottom successively behind thread billet dia necking die foremast 4, thread billet dia necking die 5 and the thread billet dia necking die.Counterdie seat cushion 9 is spun on die shoe 6 lower ends, go up and cap is spun on die shoe 6 tops, with fill up 3 behind turret head final minification mould 2, the final minification mould, pad 7 and tight behind thread billet dia necking die foremast 4, thread billet dia necking die 5 and the thread billet dia necking die.Mould push rod lasso 10 and back push rod lasso 11 place in the counterdie seat cushion 9, and mould push rod 8 lower ends are inserted in the mould push rod lasso, and fill up in 7 centre bores after being inserted in thread billet dia necking die the upper end.Back push rod guide pin bushing 14 is spun in the screw of counterdie seat cushion 9 lower central, and also cap is spun on the back push rod guide pin bushing 14 it is also tight down.Back push rod 12 is inserted in the back push rod guide pin bushing 14, and its front end is inserted in the back push rod lasso 11.
