Abstract
The utility model discloses a kind of self-clinching nut, comprise columniform nut body, the center line of nut body is provided with a through hole, and the outer circumferential face of the press-in end of nut body is provided with a circle emboss knobs, close a section of being pressed into end face of inner peripheral surface of described through hole is tapped hole, and one section away from press-in end face is smooth hole; And the height of described self-clinching nut is greater than by the thickness of casting die, in order to make when press-fiting, self-clinching nut stretches out can be smooth by riveting by the end face of casting die, thus enhance the ability of bearing and press-fiting power in the other direction.
Description
Technical field
The utility model discloses a kind of self-clinching nut.
Background technique
Tapping on the section bar that much intensity is low, can produce screw strength low, the problem that being dismounted for multiple times causes screw thread easily to destroy;
Current on low-intensity section bar tapping, be increase the intensity of screw thread, the length mainly by increasing screw thread realizes; Use and commonly press-fit nut and can improve screw strength, but can only bear one-sided stressed, for there is the screw thread press-fiting power in the other direction, commonly press-fiting nut and be difficult to solve.
Model utility content
The utility model, in order to solve the technical problem existed in prior art, the utility model discloses a kind of self-clinching nut, and the utility model combines the feature press-fiting nut and tubular-shank rivet, solves commonly to press-fit nut and can only bear one-sided stressed problem.
The technical solution adopted in the utility model is as follows:
A kind of self-clinching nut, comprise columniform nut body, the center line of nut body is provided with a through hole, and the outer circumferential face of the press-in end of nut body is provided with a circle emboss knobs, close a section of being pressed into end face of inner peripheral surface of described through hole is tapped hole, and one section away from press-in end face is smooth hole; And in order to make when press-fiting, self-clinching nut stretches out can be smooth by riveting by the end face of casting die, the aspect ratio of described self-clinching nut by the thickness height 3-6mm of casting die, riveting put down after bending edges be stuck in by casting die, enhance the ability of bearing and press-fiting power in the other direction;
In order to effectively make to be expressed in embossing teeth groove by casting die excess metal, the face area of described press-in end is greater than the face area of nut body;
The shared in vertical direction height of described tapped hole is less than or equal to by the thickness of casting die, and this can prevent the flat operation of riveting from destroying inner hole thread.
The pressing method of self-clinching nut is as follows:
The press-in side pressure of self-clinching nut enters by casting die by step 1;
Self-clinching nut stretches out by the end face riveting of casting die smooth by step 2.
The beneficial effects of the utility model are as follows:
The function press-fiting nut and tubular-shank rivet combines by the utility model, efficiently solves commonly to press-fit nut and can only bear one-sided stressed problem.
Accompanying drawing explanation
Fig. 1 is the plan view of the utility model one embodiment.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the utility model implementation result schematic diagram.
In figure: 1 body, 2 smooth holes, 3 tapped holes, 4 emboss knobs, 5 press-in end faces.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of self-clinching nut, comprise nut body 1, the center line of nut body 1 is provided with a through hole, and the outer circumferential face of the press-in end of nut body is provided with a circle emboss knobs 4, close a section of being pressed into end face 5 of inner peripheral surface of through hole is tapped hole 3, and one section away from press-in end face 5 is smooth hole 2.And in order to make when press-fiting, self-clinching nut stretches out can be smooth by riveting by the end face of casting die, the aspect ratio of described self-clinching nut by the thickness height 3-6mm of casting die, riveting put down after bending edges be stuck in by casting die, enhance the ability of bearing and press-fiting power in the other direction; In order to effectively make to be expressed in embossing teeth groove by casting die excess metal, the face area of described press-in end is greater than the face area of nut body; The shared in vertical direction height of described tapped hole is less than or equal to by the thickness of casting die, and this can prevent the flat operation of riveting from destroying inner hole thread.
The pressing method of self-clinching nut is as follows:
The press-in side pressure of self-clinching nut enters by casting die by step 1;
Self-clinching nut stretches out by the end face riveting of casting die smooth by step 2.
The function press-fiting nut and tubular-shank rivet combines by the utility model, and external shape is similar press-fits nut, and one section of internal holes close press-in end face is tapped hole, and one section away from press-in end face is smooth hole.First be pressed into this self-clinching nut by casting die during use, then by smooth for external part riveting, final implementation result schematic diagram as shown in Figure 3.
