Abstract
The utility model relates to a positive-punching blanking main die structure of a screw machine. The positive-punching blanking main die structure comprises a main die outer shell. An alloy main die is arranged at one end inside the main die outer shell. A main die sleeve pad is arranged on the end portion of the alloy main die and located in the main die outer shell. An adjusting threaded sleeve is arranged at the other end of the main die outer shell. An insert is arranged in the end portion of the alloy main die. An insert hole is formed in the insert. A blanking tube is arranged in the middle of the main die sleeve pad and the middle of the adjusting threaded sleeve. A through hole is formed in the center of the alloy main die, penetrates through the main die sleeve pad and is connected with the blanking tube. The diameter of the through hole is larger than that of the insert hole. Through adoption of the structure, the screw machine is provided with the positive-punching blanking structure, so that the screw machine can be used for machining sleeve type parts. On the condition that the length machining capacity of a nut molding machine is exceeded or the nut machine does not exist, an improved screw molding machine can be used for machining the sleeve type parts. The positive-punching blanking main die structure of the screw machine is simple, convenient and easy to operate, and saves equipment cost and die cost.
Description
Technical field
The utility model relates to the mould structure in a kind of hardware industry, especially relates to a kind of filature square impact blanking master mode structure.
Background technology
At present, the original a kind of nut make-up machine of enterprise can be beaten the long sleeve part of 25mm at most, for just carrying out processing greater than the long part of 25mm, and there is a kind of screw forming machine can process shaft-like part greater than 25mm length now, this main mode structure comprises main mould shell 5 as shown in Figure 1, main die sleeve pad 2 is fixedly arranged at the bottom at the alloy master mould 1 of main mould shell 5 inside, 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 and promotes thimble structures 15 compression springs 14 waste material is ejected, afterwards, butt rocking arm 16 returns to original position, and spring 14 also returns to original position with thimble structure 15; Existing this structure is owing to there is the existence of butt rocking arm 16, in the longer sleeve part of needs manufacturing, just need transform butt rocking arm 16, this machine does not have square impact technology 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 transform it.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of filature square impact blanking master mode structure of having cancelled butt rocking arm and suitable sleeve part production technology.
The technical scheme in the invention for solving the technical problem is: 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, on the end of alloy master mould, be provided with main die sleeve pad in the main mould shell, 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 at the center of alloy master mould and run through main die sleeve pad and be connected with material blanking tube, 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 first diameter of bore of inserting is less than second diameter of bore of inserting.
For convenience material blanking tube is fixed on the main die sleeve pad, and through hole and blanking pore be 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 beneficial effects of the utility model are: adopted after the said structure, make screw forming machine have square impact blanking structure, can make it to process sleeve part, under the situation that exceeds nut make-up machine processing length ability or do not have under the situation of nut machine, can use improved screw forming machine to come the processing sleeve part.This convenience simple in structure is operated easily, saves equipment cost and die cost.
Description of drawings
Fig. 1 is the structural representation of screw forming machine;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the local enlarged diagram of A part among Fig. 2.
Among the figure: 1, alloy master mould; 2, main die sleeve pad; 3, material blanking tube; 4, adjust swivel nut; 5, main mould shell; 6, through hole; 7, first insert; 8, second insert 9, the hole of inserting; 10, hole type parts; 11, punching pin; 12, material returned sleeve 13, alloy punch die 14, spring; 15, thimble structure; 16, butt rocking arm; 17, technology clout.
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, on the end of alloy master mould 1, be provided with main die sleeve pad 2 in the main mould shell 5, 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 part of a last operation between punch die and the main mould, carry out cold extrusion, the punching pin 11 of punch die will be gone up an operation blind hole part and be washed into hole type parts 10, and technology clout 17 is pushed into second and inserts in 8 the hole, the punching pin 11 of punch die is being with hole type parts 10 to retreat subsequently, then material returned sleeve 12 advances to main mould direction, and hole type parts 10 is released hole type parts 10 blankings from punching pin 11.By that analogy, the technology clout promotes the technology clout, enters in the material blanking tube 3 along through hole 6, from the end of material blanking tube 3 clout that falls, enters in the collecting receptacle.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
