Description
Technical field
The utility model relates to auto parts and components field, is specifically related to a kind of HI type punching nut.
Background technique
HI type punching nut integrates from punching, self-fastening technology, and its attachment portion has good to draw, press, turns round performance, simple, efficient, environmental protection, is convenient to automatic assembly line and produces, in the manufacture field of automobile, have extensive use.As shown in Figure 1, (namely cross section is H-shaped to existing HI type, longitudinal section is I shape) respectively there is a groove 1 ' bi-side of punching nut, the both sides of this groove 1 ' are dovetail face 2 ', for realizing the self-fastening function of nut, but this kind of HI type punching nut to the dimensional accuracy of section bar and technical requirements higher, and be subject to the restriction of traditional cold-drawn equipment processing ability, the dovetail face of the HI type punching nut that domestic existing cold-drawing technology is produced all does not reach use standard, cold-rolling process must be adopted could to meet the size of HI type punching nut to section bar and the requirement of technology, but develop special cold-rolling equipment, existence involves great expense, waste of material is large, user cost is high, and the problems such as work flow complexity, therefore can not practical requirement well.
Model utility content
The utility model, in order to overcome above deficiency, provides that a kind of reliable for effect, production technology is simple, easily processing and the low HI type punching nut of cost.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of HI type punching nut, comprise body, run through the tapped hole in the middle part of body and be located at the first groove of tapped hole both sides, the longitudinal section of described first groove is the rectangular configuration of upper side opening.
Further, described tapped hole two bottom sides is provided with the second groove that Open Side Down.
Further, the longitudinal section of described second groove is arch structure.
Further, the cross section of described body is rectangle.
Further, the surface of described body is provided with anticorrosive coat.
Further, described body adopts carbon steel or stainless steel or copper or alloy to make.
Further, the upper surface of described body is with the globoidal structure of described tapped hole symmetry.
Further, the pitch of described tapped hole internal thread is equal.
The HI type punching nut that the utility model provides, comprises body, runs through the tapped hole in the middle part of body and is located at the first groove of tapped hole both sides, and the longitudinal section of described first groove is the rectangular configuration of upper side opening; By arranging the first groove in tapped hole both sides, and make the longitudinal section of the first groove be the rectangular configuration of upper side opening, not only can realize the self-fastening function of body, and structure is simple, reduce the requirement of dimensional accuracy to section bar and technology, decrease equipment investment and cost of production.The utility model good manufacturability, production technology are simple, manufacturing efficiency is high, waste of material is few, with short production cycle, manufacturing expense is cheap, easy processing, reliable for effect, meet actual demand well.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing HI type punching nut;
Fig. 2 is the structural representation of the utility model HI type punching nut.
Shown in Fig. 1: 1 ', groove; 2 ', dovetail face;
Shown in Fig. 2: 1, body; 2, tapped hole; 3, the first groove; 4, the second groove.
Embodiment
Below with reference to accompanying drawing, the utility model is further described:
As shown in Figure 2, a kind of HI type punching nut, comprise body 1, run through the tapped hole 2 in the middle part of body 1 and be located at the first groove 3 of tapped hole 2 both sides, the longitudinal section of the first groove 3 is the rectangular configuration of upper side opening, by arranging the first groove 3 in tapped hole 2 both sides, and make the longitudinal section of the first groove 3 be the rectangular configuration of upper side opening, not only can realize the self-fastening function of body 1, and structure is simple, reduce the requirement of dimensional accuracy to section bar and technology, decrease equipment investment and cost of production.
Continue referring to Fig. 2, the two bottom sides of tapped hole 2 is provided with the second groove 4 that Open Side Down, concrete, and the position of the second groove 4 is corresponding with the first groove 3, for improving the self-fastening performance of body 1 further, improves fastening effect.
Preferably, the longitudinal section of the second groove 4 is arch structure, can adopt that tratitional technology is disposable to be stamped to form, and makes simple.
Preferably, the cross section of body 1 is rectangle, determines the concrete size of body 1 according to actual needs, certainly, also can be designed to square.
Preferably, the surface of body 1 is provided with anticorrosive coat, in order to improve the working life of HI type punching nut, reduce and change difficulty, coat anticorrosive coat (not marking in figure) on the surface of body 1, concrete, anticorrosive coat can be rubber layer, synthesize an entirety by viscose glue and body 1 face seal heat of vulcanization, avoid water and the surface of various erosion to body 1 to cause corrosion, thus affect replacing difficulty and the working life of HI type punching nut.
Preferably, body 1 adopts carbon steel or stainless steel or copper or alloy to make, according to actual needs, select the material of HI type punching nut, under normal circumstances, mainly consider the heat resistance of nut, intensity and solderability, the respective performances according to carbon steel, stainless steel, copper and alloy is selected, simultaneously good to draw to ensure that nut has, press, turn round performance, two kinds and above material also can be adopted to make.
Preferably, the upper surface of body 1 is with the globoidal structure of tapped hole 2 symmetry.
Preferably, the pitch of tapped hole 2 internal thread is equal, improves its fastening performance further.
In sum, the HI type punching nut that the utility model provides, the longitudinal section of the first groove 3, first groove 3 comprising body 1, run through the tapped hole 2 in the middle part of body 1 and be located at tapped hole 2 both sides is the rectangular configuration of upper side opening.By arranging the first groove 3 in tapped hole 2 both sides, and its longitudinal section is designed to the rectangular configuration of upper side opening, not only can realize the self-fastening function of body 1, and structure is simple, reduce the requirement of dimensional accuracy to section bar and technology, decrease equipment investment and cost of production.The utility model good manufacturability, production technology are simple, manufacturing efficiency is high, waste of material is few, with short production cycle, manufacturing expense is cheap, easy processing, reliable for effect, meet actual demand well.
