Abstract
The invention discloses a solid self-punching rivet, comprising a rivet cap and a rivet rod, wherein a conical port is arranged between the rivet cap and the rivet rod, the rivet rod is in a cylindrical shape, and at least one circle of an annular groove is arranged on the outer circumferential surface of the rivet rod. When in use, the solid self-punching rivet can be directly punched through a punch of a press machine, the rivet rod passes through plates to be connected, so that part of plates are extruded into the annular groove, and therefore, the plates are firmly connected together. Two-layer plates or multilayer plates can be connected together by using the solid self-punching rivet, the riveting process is simple, and before the plates are riveted, the solid self-punching rivet can be punched to the plates in one step without carrying out opening on the plates; the solid self-punching rivet can be used for riveting various plates difficult to weld, has stable riveting quality, can achieve firm and consistent riveting effect, and has no smoke generation or environmental pollution in a riveting process. When used for riveting, the solid self-punching rivet is easy to realize automation so that production efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of rivet, particularly a kind of solid self-pierce riveting nail.
Background technique
In the production and construction process, often the two boards material need be linked together, the method that at present the two boards material is coupled together mainly contains: carry out mechanical connection by welding or by screw-nut, pulling rivet, the nail that presses etc., above-mentioned two kinds of methods all exist certain drawback.When at first adopting the electric welding welding, when on two kinds of sheet material differences or the sheet material coating being arranged, just be difficult to the two boards material is linked together by welding method, there is the welding method of employing to be easy to make sheet deformation again, and in welding process, tend to produce a large amount of flue gases, can pollute environment.And by screw-nut, pulling rivet, the nail that presses etc. when carrying out mechanical connection, often need perforate in advance on sheet material, therefore couple together comparatively trouble, manufacturing process is loaded down with trivial details, and manufacturing efficiency is low, and influence is produced or the speed of construction.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention provides a kind of simple in structure, easy to use, can connect two-ply or multiple-plate solid self-pierce riveting nail fast.
For solving the problems of the technologies described above, the present invention adopts following technological scheme:
A kind of solid self-pierce riveting nail comprises rivet cap and rivet bar, is provided with a conus portion between described rivet cap and the rivet bar, and described rivet bar is cylindric, and the outer circumferential face of described rivet bar is provided with the annular grooving of at least one circle.
Preferably, described rivet cap is cylindric.
Preferably, the outer circumferential face of described rivet bar is provided with the annular grooving of two circles.
Technique scheme has following beneficial effect: this solid self-pierce riveting nail can pass through the direct punching press of press ram in use, make rivet bar pass the sheet material that will connect, a sheet material part just is extruded in the annular grooving like this, thereby with firm the linking together of sheet material.Use this solid self-pierce riveting nail two-ply or sandwich plate can be linked together, the riveted joint process is simple, need not perforate before riveted joint on the sheet material, through once finishing towards riveting; Can rivet the sheet material of various difficult welding, riveting quality is stable, can reach the riveted joint effect of firm unanimity, and in the generation of riveted joint process non smoke, free from environmental pollution, adopt this solid self-pierce riveting nail riveted joint to realize automation easily, can significantly improve the efficient of production.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. describe in detail as after.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.

Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, 2, this solid self-pierce riveting nail comprises rivet cap 1 and rivet bar 3, is provided with a conus portion 2 between rivet cap 1 and the rivet bar 3, and rivet cap 1, rivet bar 3 all are cylindric, and the outer circumferential face of rivet bar 3 is provided with the annular grooving 4 of two circles.
As shown in Figure 3, this solid self-pierce riveting nail is placed on sheet material 7,8 between counterdie 9 and the pressed edge ring 6 in use, and sheet material 7,8 can be steel plate, aluminium sheet or corrosion resistant plate.Should be placed in the pressed edge ring 6 by solid self-pierce riveting nail then, make the drift 5 downward punching presses of press machine, solid like this self-pierce riveting is followed closely with regard to penetrable sheet material 7,8, and goes out part metals simultaneously.Under the co-extrusion of the reaction force of drift 5 impulse forces and counterdie 9, the part of sheet material 7,8 is extruded in the annular grooving 4, so both can be with sheet material 7,8 firm being riveted together.Stamping-out is sheared and is pushed two processes in the riveted joint process of this solid self-pierce riveting nail, and the number of turns of annular grooving 4 can be provided with as required, when at least a circle being arranged, so just can make sheet material 7,8 by firm pressing together, the assurance riveting quality.
This solid self-pierce riveting nail can pass through the direct punching press of press ram in use, makes rivet bar pass the sheet material that will connect, and a sheet material part just is extruded in the annular grooving like this, thereby with firm the linking together of sheet material.Use this solid self-pierce riveting nail two-ply or sandwich plate can be linked together, the riveted joint process is simple, need not perforate before riveted joint on the sheet material, through once finishing towards riveting; Can rivet the sheet material of various difficult welding, riveting quality is stable, can reach the riveted joint effect of firm unanimity, and in the generation of riveted joint process non smoke, free from environmental pollution, adopt this solid self-pierce riveting nail riveted joint to realize automation easily, can significantly improve the efficient of production.
More than a kind of solid self-pierce riveting nail was described in detail to the embodiment of the invention provides; for one of ordinary skill in the art; thought according to the embodiment of the invention; part in specific embodiments and applications all can change; in sum; this description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
