Abstract
The invention relates to a square pressure riveting nut which comprises a nut body. A thread hole is arranged in the middle of the nut body; the head of the nut body is provided with a flange; a step is arranged below the flange which adopts a conical surface form with wide upper part and narrow lower part; the step is also provided with a protruded rib bar; and a connection part of the flange and the step is provided with a guiding groove in circular arc transition. By adopting the structure, the square nut is firmly arranged on a steel plate and can be also connected with other components. Smog, heat, sparkles, dust, scraps and welding noises are not generated in the installation process, so that the security of the process and the cleanliness of work environment are improved, the damage to the body of staffs is reduced so as to meet the development trend of green industry in the future; and the intensity of the riveting point is high, the service life is long, the riveting quality is continuous and stable, and the collision-prevention performance is greatly improved.
Description
Technical field
The present invention relates to a kind of nut, especially relate to the cubic self-clinching nut that uses on a kind of automobile.
Background technique
At present, the most popular sides nut mounting process in automotive industry Zhong Men position is to utilize welding machine that sides nut is welded on the steel plate, it is reliable that this connection technology has been proved to be in production in enormous quantities, but sides nut welding procedure energy consumption is big, welding quality is unstable, welding back sheet material is yielding, whole not attractive in appearance, the terminal vulnerable to pollution in welding back of product, shortens shortcomings such as soldering tip working life.
Summary of the invention
Technical problem to be solved by this invention provides a kind of cubic self-clinching nut, and it can substitute the mode of traditional welding nut and use on automobile.
The present invention solves the technological scheme that its technical problem takes: a kind of cubic self-clinching nut, comprise nut body, be provided with tapped hole in the middle of the nut body, described nut body head is provided with flange, the below of flange is provided with step, and flange adopts conical surface form wide at the top and narrow at the bottom.
For the effect that makes riveted joint is more outstanding, also be provided with the rib of projection on the described step.
In order to make things convenient for material to flow, can combine closely, there is the guiding grooving of arc transition the joint of described flange and step.
Adopted after the said structure, just very firm being installed on the steel plate of sides nut can connect other component again; And in installation process, do not produce smog, empty calory, spark, dust, chip and welding noise, improved the Security of technology and the spatter property of working environment, reduce injury, meet following green industrial expansion trend staff's health; Also have riveting point intensity height, the life-span is long, and riveting quality is continual and steady, and crashworthiness increases substantially.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is a use schematic representation of the present invention.
Among the figure: 1, tapped hole 2, flange 3, guiding grooving 4, rib 5, step 6, sheet material 7, nut body
Embodiment
The present invention is further described below in conjunction with accompanying drawing.
A kind of as depicted in figs. 1 and 2 cubic self-clinching nut comprises nut body 7, is provided with tapped hole 1 in the middle of the nut body 7, and described nut body 7 heads are provided with flange 2, and the below of flange 2 is provided with step 5, and flange 2 adopts conical surface form wide at the top and narrow at the bottom; Also be provided with the rib 4 of projection on the described step 5; There is the guiding grooving 3 of arc transition the joint of described flange 2 and step 5.
Be pressed in the sheet material 6 with press at afterbody as shown in Figure 3, rib 4 is stuck in the steel plate just have been fixed, the front end head is the conical surface and has guiding grooving 3, the sheet material that will fix 6 is pressed into along the conical surface, because front end has guiding grooving 3, when being pressed into, sheet material 6 just produces plastic deformation, deformations just is squeezed into 3 li of guiding groovings, is pressed into after the desired position, and nut body 7 and sheet material 6 are with regard to firm having linked together.
The four directions self-clinching nut is a kind of nut that is applied on thin plate or the panel beating, and profile is square, and two ends have rib 4 and guiding grooving 3.Its principle is to be pressed in the cubic hole of presetting of panel beating by rib 4, generally speaking the length that presets cubic hole is slightly less than the length of the rib 4 of cubic self-clinching nut, the both sides that the rib 4 of cubic self-clinching nut clamp-oned make cubic hole in the plate by pressure produce plastic deformation, deformations is squeezed into guiding grooving 3, thereby produces the effect of locking.
Claims (3)
1. cubic self-clinching nut, comprise nut body (7), be provided with tapped hole (1) in the middle of the nut body (7), it is characterized in that: described nut body (7) head is provided with flange (2), the below of flange (2) is provided with step (5), and flange (2) adopts conical surface form wide at the top and narrow at the bottom.
