Abstract
The invention relates to a blind rivet, in particular to a blind rivet with double countersunk heads and used for continuously riveting, belonging to the technical field of fasteners. The core pulling rivet with the double countersunk heads comprises at least one rivet barrel and a rivet core arranged in the rivet barrel, wherein the rivet barrel is provided with a through hole along an axial direction; the two ends of the rivet barrel are respectively provided with a first limit bulge loop and a second limit bulge loop; the rivet core comprises a rivet rod and a rivet head connected onto the rivet rod; the two ends of the rivet head are respectively provided a first circular truncated cone body and a second circular truncated cone body; and the diameter at the most widest part of the rivet head is bigger than the diameter of the inner hole of the rivet barrel. The core pulling rivet with the double countersunk heads is rapid and convenient in operation, smooth at two sides after being used for riveting and wide in application, and is capable of saving the energy and protecting the environment.
Description
Technical field
The present invention relates to a kind of self-plugging rivet, a kind of two countersunk heads that can rivet continuously draw the sky rivet specifically, belong to technical field of fastening.
Background technique
Along with the fast development of Chinese national economy, the hardware fastening industry has reached unprecedented prosperity.Along with automobile industry, mechanical processing industry, electronic device, aerospace developing rapidly, increasing as the demand of the rivet of hardware accessory, throughput is surged, and the localization rate of parts and components reaches quite high level, and quality is also improving constantly.
After China joined WTO, the domestic and international market is integrated, and competition has brought pressure also along with aggravation to enterprise, has also brought infinite commercial opportunities.It is predicted, the annual requirement of present global rivet is over trillion.And the foreign exchange earning average annual growth rate of China's rivet is more than 15%.In evolution, high in technological content products efficient, energy-saving and environmental protection will inevitably be widely adopted.And traditional rivet product, neither energy-conserving and environment-protective, efficient are low again, also can cause quality influence to some fasteners that quality is had relatively high expectations, and can't adapt to Protean market.
Present domestic rivet enterprise begun from the low grade products of high pollution, high energy consumption progressively to lowly pollute, the high-tech product of low energy consumption shifts, but compare the also larger gap of existence with international most advanced level, at variety development, improve quality, the aspect such as reduce costs, also shoulder heavy responsibilities.
Residual blind rivet generally all can occur and come off in traditional rivet, causes the hidden trouble of electrical short-circuit, quick rivet, after riveted joint, the one side out-of-flatness has boss, be equipped with impact to the thin plate confined space is two-sided, though and draw that sky rivet two sides is smooth has useless blind rivet to come off, and neither material is wasted again in environmental protection.
Because these problems cause some to watch server, storage etc. and can not select rivet to connect, further squeeze into high-grade, precision and advanced market thereby suppressed the rivet product.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, thereby provide a kind of pair of countersunk head to draw the sky rivet, with quick rivet and draw the sky rivet to unite two into one, solve the uneven problem that arranges, draws the sky rivet to have useless nail to come off in quick rivet two sides, the purpose of accurately accomplishing energy-conserving and environment-protective, cleaner production.
According to technological scheme provided by the invention, two countersunk heads draw the sky rivet to comprise at least one nail barrel and the blind rivet that is arranged in nail barrel, be provided with vertically through hole in nail barrel, it is characterized in that: the two ends of described nail barrel are respectively equipped with the first position limiting convex ring and the second position limiting convex ring, described blind rivet comprises the nail bar and is connected to the ailhead of nail on bar, and ailhead two ends are respectively equipped with the first Rotary-table and the second Rotary-table.Described ailhead the widest position diameter is greater than the nail barrel diameter of bore.
Further, the nail barrel outer wall is provided with at least two annular grooves.
Further, the through hole two ends are the counter sink of 120 °.
Further, ailhead is oblate shape.
Further, the angle of the bus of the first Rotary-table and ailhead center line is 60 °.
Further, the angle of the bus of the second Rotary-table and ailhead center line is 120 °.
Compared with the prior art the present invention has the following advantages:
1, operation is quick and convenient, and after riveted joint, the two sides is smooth, can unrestrictedly plug parts;
2, energy-conserving and environment-protective, blind rivet can be used continuously, is scattered without useless blind rivet, saves material than mill run;
3, purposes is wide, establishes especially the high-end product scopes such as hop server, storage, servomechanism.

Description of reference numerals: 1-blind rivet, 2-nail barrel, 3-ailhead, 4-nail bar, 5-the first Rotary-table, 6-the second Rotary-table, 7-the first position limiting convex ring, 8-the second position limiting convex ring, 9-annular groove, 10-through hole.
Embodiment
Following the present invention is further described in connection with the embodiment in accompanying drawing:
As shown in Fig. 1 ~ 3, the present invention mainly comprises at least one nail barrel 2 and the blind rivet 1 that is arranged in nail barrel 2, be provided with vertically through hole 10 in described nail barrel 2, the two ends of nail barrel 2 are respectively equipped with the first position limiting convex ring 7 and the second position limiting convex ring 8, nail barrel 2 outer walls are provided with at least two annular grooves 9, annular groove 9 is convenient to blind rivet 1 and is deformed smoothly by nail barrel 2 time, makes simultaneously riveted joint firmly.
Described through hole 2 two ends are the counter sink of 120 °, be not only applicable to the riveted joint in countersunk head type hole, but also be applicable to the riveted joint of common straight hole, during the riveting straight hole, utilize the toughness of nail barrel 2 metallic material, the second position limiting convex ring 8 can be out of shape by special riveting gun head extruding, forms the oblate head dummy that adapts to straight hole.
Described blind rivet 1 comprises nail bar 4 and is connected to the ailhead 3 of following closely on bar 4, ailhead 3 is oblate shape, ailhead 3 two ends are respectively equipped with the first Rotary-table 5 and the second Rotary-table 6, the angle of the bus of the first Rotary-table 5 and ailhead 3 center lines is 60 °, and the angle of the bus of the second Rotary-table 6 and ailhead 3 center lines is 120 °.
Described ailhead 3 the widest position diameters are greater than nail barrel 2 diameter of bores, and when the first Rotary-table 5 of blind rivet 1 passed nail barrel 2 endoporus, first Rotary-table 5 compressing the second position limiting convex rings 8 made its distortion be close to the riveted holes inwall; After blind rivet 1 is passed nail barrel 2, draw back blind rivet 1, second Rotary-table 6 compressing the first position limiting convex rings 7 of blind rivet 1 make its distortion be close to the riveted holes inwall, have so just completed riveted joint, reach the two sides smooth.
