Abstract
The invention relates to a filature square punching blanking fundamental mould structure which comprises a fundamental mould outer shell, wherein one end inside the fundamental mould outer shell is provided with an alloy fundamental mould, a fundamental mould sleeve cushion is arranged on the end portion of the alloy fundamental mould and inside the fundamental mould outer shell, and the other end of the fundamental mould outer shell is provided with a regulating swivel nut. An insert provided with an insert hole is arranged inside the end portion of the alloy fundamental mould, a blanking pipe is arranged between the fundamental mould sleeve cushion and the regulating swivel nut, a through hole formed in the center of the alloy fundamental mould penetrates through the fundamental mould sleeve cushion and is connected with the blanking pipe, and the diameter of the through hole is larger than that of the insert hole. After the structure is utilized, a bolt former is provided with the square punching blanking structure, sleeve type parts can be machined, and on the conditions that nut former length machining performance is exceeded or a nut machine does not exist, the reformed bolt former is used for machining the sleeve type parts. The structure is simple, and convenient and easy to operate, saves equipment cost and mould cost.
Description
Technical field
The present invention relates to the mould structure in a kind of hardware industry, especially relate to a kind of filature square impact blanking master mode structure.
Background technology
at present, the original a kind of nut forming machine of enterprise can be beaten at most the long sleeve part of 25mm, for just carrying out processing greater than the long part of 25mm, and there is now a kind of screw forming machine can process shaft-like part greater than 25mm length, this main mode structure comprises main mould shell 5 as shown in Figure 1, bottom at the alloy master mould 1 of main mould shell 5 inside is fixed with main die sleeve pad 2, and by spring 14, the combination of thimble structure 15 and butt rocking arm 16 reaches the effect of blanking, butt rocking arm 16 rotates promotion thimble structure 15 Compress Springs 14 waste material is ejected, afterwards, butt rocking arm 16 returns to original position, spring 14 also returns to original position with thimble structure 15, existing this structure is due to the existence that butt rocking arm 16 is arranged, in the longer sleeve part of needs manufacturing, just need to transform butt rocking arm 16, this machine is without square impact technique clout blanking channel in addition, it is the square impact method production technology that is not suitable for sleeve part, in order to achieve the goal, so need to transform it.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of filature square impact blanking master mode structure of having cancelled butt rocking arm and suitable hole type parts production technology.
the present invention solves the technical scheme that its technical problem takes: a kind of filature square impact blanking master mode structure, comprise main mould shell, one end is provided with alloy master mould in the inside of main mould shell, be provided with main die sleeve pad in main mould shell on the end of alloy master mould, the other end at main mould shell is provided with the adjustment swivel nut, be provided with in the end of described alloy master mould and insert, insert and be provided with the hole of inserting, middle part at main die sleeve pad and adjustment swivel nut is provided with material blanking tube, be provided with a through hole runs through main die sleeve pad and is connected with material blanking tube at the center of alloy master mould, through-hole diameter is greater than the bore dia of inserting.
In order conveniently to go out clout, further concrete, the described center of inserting is provided with stepped hole.
Further concrete, described inserting inserted and second inserted and form by first, and the first diameter of bore of inserting is less than the second diameter of bore of inserting.
For convenient, material blanking tube is fixed on main die sleeve pad, and through hole with the blanking pore effectively to being connected into a long through-hole, further concrete, described main die sleeve pad is threaded with the material blanking tube employing.
The invention has the beneficial effects as follows: after having adopted said structure, make screw forming machine have square impact blanking structure, can make it to process sleeve part, in the situation that exceed nut forming machine processing length ability or there is no nut machine, can come the processing sleeve part with improved screw forming machine.This convenience simple in structure easily operates, and saves equipment cost and die cost.
Description of drawings

The specific embodiment
A kind of filature square impact blanking master mode structure as shown in Figure 2, comprise main mould shell 5, an end is provided with alloy master mould 1 in the inside of main mould shell 5, be provided with main die sleeve pad 2 in main mould shell 5 on the end of alloy master mould 1, the other end at main mould shell 5 is provided with adjustment swivel nut 4, be provided with in the end of described alloy master mould 1 and insert, insert and be provided with the hole 9 of inserting, middle part at main die sleeve pad 2 and adjustment swivel nut 4 is provided with material blanking tube 3, be provided with a through hole 6 at the center of alloy master mould 1 and run through main die sleeve pad 2 and be connected with material blanking tube 3, through hole 6 diameters are greater than hole 9 diameters of inserting; Described insert to insert by first 7 and second insert and 8 form, first inserts 7 diameter of bore less than second 8 the diameter of bore of inserting; Described main die sleeve pad 2 adopts with material blanking tube 3 and is threaded.
As shown in Figures 2 and 3, at first, clip clips to the blind-hole parts of a upper operation between punch die and main mould, carry out cold extrusion, the punching needle 11 of punch die is washed into hole type parts 10 with a upper operation blind-hole parts, and technique clout 17 is pushed into second and inserts in 8 hole, the punching needle 11 of punch die retreats with hole type parts 10 subsequently, then material returned sleeve 12 advances to main mould direction, hole type parts 10 is released hole type parts 10 blankings from punching needle 11.By that analogy, the technique clout promotes the technique clout, enters in material blanking tube 3 along through hole 6, from the end of material blanking tube 3 clout that falls, enters in collecting receptacle.
It is emphasized that: above is only preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
