The production technology of system is punching and riveting, and the characteristics of this mode of production is the first punching on stamping parts, then nut is put into hole
In riveted, that is, need two procedures, two lathes, two employees are produced, and are not only wasted lathe, are also reduced production
Efficiency, and there is also the situation of leakage riveting nut during mass production, influence the quality of product.
Utility model content
Against the above deficiency, the purpose of this utility model is that, a kind of smart structural design, reasonable, work efficiency are provided
High nut stud riveting die.
To achieve the above object, technical solution provided by the utility model is：A kind of nut stud riveting die, including
Upper mold seat, upper clamp plate, stripper plate, lower template, lower bolster, die holder, riveting punch and nut pilot pin, the die holder pass through
Bottom seat pad is fixed on lower pallet；The die holder, lower bolster, lower template, stripper plate, upper clamp plate and upper mold seat are by from bottom to up
Order is sequentially stacked, and the lower template is equipped with the positioning putting hole for being used for placing stud, the spiral shell towards the surface of stripper plate
Female pilot pin is arranged on a side position of the positioning putting hole；The upper end of the riveting punch is fixed on upper clamp plate, and lower end is passed through
Wear off flitch and towards the nut pilot pin.
As a kind of improvement of the utility model, the lower end radial protrusion of the nut pilot pin forms card convex portion, top
It radially reduces and forms positioning region, the card convex portion is fixed in lower template, and positioning region is stretched out from the upper surface of lower template；The riveting
The lower face for connecing punch is equipped with the positioning sets of holes being adapted with the positioning region.
As a kind of improvement of the utility model, the head of the positioning region is equipped with chamfering.
As a kind of improvement of the utility model, the upper end radial protrusion of the riveting punch forms boss.
As a kind of improvement of the utility model, the stud is hexagon stud.
The beneficial effects of the utility model are：Stud, during work, is placed on positioning by the utility model clever structure, rationally
It is sleeved on putting hole and nut on the positioning region of nut pilot pin, and sheet metal component is located in lower template, forcing press promotes mold
It starts, forms punch structure using its rigidity of stud and nut, the surface of sheet metal component is directly pierced through and is pressed into metal plate by realization
In golden part, cooperation is close, is connected firmly, not only ensures riveting intensity, but also improves work efficiency, and ensures product quality,
In addition overall simple, it is easy to accomplish, it is at low cost, beneficial to being widely popularized.
Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of nut pilot pin in the utility model.
Specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of nut stud riveting die provided in this embodiment, including upper mold seat 1, upper clamp plate 2,
Stripper plate 3, lower template 4, lower bolster 5, die holder 6, riveting punch 7 and nut pilot pin 8, the die holder 6 pass through bottom seat pad 9
It is fixed on lower pallet 10；The die holder 6, lower bolster 5, lower template 4, stripper plate 3, upper clamp plate 2 and upper mold seat 1 press from down toward
Upper order is sequentially stacked, and the lower template 4 is equipped with the positioning putting hole for being used for placing stud 11 towards the surface of stripper plate 3
41, the nut pilot pin 8 is arranged on a side position of the positioning putting hole 41；The upper end of the riveting punch 7 is fixed on
On clamping plate 2, lower end is through stripper plate 3 and towards the nut pilot pin 8.
Specifically, the lower end radial protrusion of the nut pilot pin 8 forms card convex portion 81, top, which radially reduces, forms positioning
Portion 82, the card convex portion 81 are fixed in lower template 4, and positioning region 82 is stretched out from the upper surface of lower template 4；The riveting punch 7
Lower face be equipped with the positioning sets of holes that are adapted with the positioning region 82.
Preferably, the head of the positioning region 82 is equipped with chamfering 83, it more can conveniently be inserted in nut 12 and stretch into positioning sets of holes.
The upper end radial protrusion of the riveting punch 7 forms boss, effectively promotes the fitment stability with upper clamp plate 2.
In the present embodiment, the stud 11 is preferably hexagon stud.
During work, stud 11 is placed on positioning putting hole 41 and nut is sleeved on the positioning region 82 of nut pilot pin 8,
