Abstract
The utility model relates to riveting nut field, specifically disclose a kind of self-clinching nut of the sheet metal part that comes off for nut, it comprises nut body parts and riveting limiting-members, nut body parts are arranged on one end of self-clinching nut and riveting limiting-members is arranged on the other end, and the diameter of self-clinching nut riveting limiting-members is increase by 0.8 millimeter again on the riveting fixed structure external diameter of separation nut.Beneficial effect: make self-clinching nut regain the material space pressed on foramen primum position by enlarged.Meanwhile, diameter only carries out micro-increasing of 0.8 millimeter, is conducive to reducing materials, production control cost.
Description
Technical field
The utility model relates to self-clinching nut field, is specifically related to a kind of self-clinching nut of the sheet metal part that comes off for nut.
Background technique
Under the impact of the factor such as current process and cost, if the situation that the sheet metal part nut being provided with riveting nut comes off, same specification nut is then used to be difficult to carry out secondary riveting at this sheet metal part, thus a large amount of sheet metal part material in good condition is caused to use, cause materials waste, add cost of production.
Model utility content
Technical problem to be solved in the utility model is: the self-clinching nut providing a kind of sheet metal part that comes off for nut, it is different from the riveting nut of regular size, can with the sheet metal part come off for nut, can utilize on sheet metal part on position, former riveting hole and carry out secondary installing, thus product recycling can be realized, reduce use enterprise's cost of production and the technical program structure simple, press easy to operate.
For solving the problems of the technologies described above, the technological scheme that the utility model provides: a kind of self-clinching nut of the sheet metal part that comes off for nut, it comprises nut body parts and riveting limiting-members, nut body parts are arranged on one end of self-clinching nut, and riveting limiting-members is arranged on the other end, the diameter of self-clinching nut riveting limiting-members is increase by 0.8 millimeter again on the riveting fixed structure external diameter of separation nut.
The scheme of further optimization, riveting limiting-members comprises material extrusion grooved ring and straight-tooth anti-japanese bearbind line ring.
The scheme of further optimization, straight-tooth anti-japanese bearbind line ring is arranged on the outer end of riveting limiting-members, and material extrusion grooved ring is arranged on straight-tooth anti-japanese bearbind line ring and nut body parts.
After have employed technique scheme, the beneficial effects of the utility model are:
The technical program carries out micro-increasing again on the basis of regular size riveting limiting-members diameter, is specially increase by 0.8 millimeter, makes self-clinching nut on foramen primum position, regain the material space pressed by enlarged.Meanwhile, diameter only carries out micro-increasing, is conducive to reducing materials, production control cost.
Accompanying drawing explanation
The nut of Fig. 1 riveting on sheet metal part comes off
The self-clinching nut of a kind of sheet metal part that comes off for nut of Fig. 2
The diameter of self-clinching nut of a kind of sheet metal part that comes off for nut of Fig. 3
The pressing of self-clinching nut of a kind of sheet metal part that comes off for nut of Fig. 4
Embodiment
Below in conjunction with accompanying drawing 1 to accompanying drawing 4 and specific embodiment, the utility model is described in detail, but not as to restriction of the present utility model.
As shown in accompanying drawing 2 and accompanying drawing 3, a kind of self-clinching nut of the sheet metal part that comes off for nut, it comprises nut body parts 1 and riveting limiting-members 2, nut body parts 1 are arranged on one end of self-clinching nut, and riveting limiting-members 2 is arranged on the other end, it is characterized in that: the diameter of self-clinching nut riveting limiting-members 2 is increase by 0.8 millimeter again on the riveting fixed structure external diameter of separation nut.
As shown in figure accompanying drawing 2, on the basis of above-described embodiment, riveting limiting-members 2 comprises material extrusion grooved ring 21 and straight-tooth anti-japanese bearbind line ring 22.Straight-tooth anti-japanese bearbind line ring 22 is arranged on the outer end of riveting limiting-members 2, and material extrusion grooved ring 21 is arranged on straight-tooth anti-japanese bearbind line ring 22 and nut body parts 1.
As shown in Figure 2, the specific works principle of straight-tooth anti-japanese bearbind line ring 22 and material extrusion grooved ring 21 is: anti-for straight-tooth japanese bearbind line ring 22 is pressed into preset holes position, generally speaking the aperture of preset holes position is slightly less than the radius of straight-tooth anti-japanese bearbind line ring 22, straight-tooth anti-japanese bearbind line ring 2 is made to clamp-on in the sheet material around preset holes position by pressure, make causing hole periphery produce plastic deformation, and then deformations is clamp-oned in material extrusion grooved ring 21, thus copper post and the place's of pressing generation are stung tightly, thus reach the effect pressed.
As shown in Figure 1, sheet metal part generation nut come off be difficult to carry out one of reason that secondary presses with the nut of same specification be again exactly, foramen primum position 4 has not had can for the material that presses, namely after first time presses, nut sheet metal part 3 material pressed in scope in foramen primum position 4 has been squeezed destruction, when former nut comes off, part sheet metal part 3 material can come off with former nut, the space so the nut of same specification for want of presses and cannot carry out riveting in foramen primum position 4.
As shown in accompanying drawing 3 and accompanying drawing 4, what therefore the technical program provided is φ N+0.8 millimeter for the come off diameter of self-clinching nut riveting limiting-members of sheet metal part of nut, and " φ N " represents the diameter of regular size self-clinching nut riveting limiting-members.In order to overcome the above-mentioned problem being difficult to secondary and pressing, the technical program carries out micro-increasing again on the basis of regular size riveting limiting-members diameter, is specially increase by 0.8 millimeter, makes self-clinching nut on foramen primum position 4, regain the material space pressed by enlarged.Meanwhile, diameter has only carried out micro-increasing of 0.8 millimeter, is conducive to reducing materials, production control cost.
As known by the technical knowledge, the technical program can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Allly all to be included in the utility model within the scope of the utility model or being equal to the change in scope of the present utility model.
