Abstract
Provided is a minisize rotary pulling rivet. The minisize rotary pulling rivet is composed of a rivet and a lantern ring, the rivet comprises a rivet head, a polished rod, and a spiral locking section. The front section of the spiral locking section is used for squeezing and matching with the lantern ring, and the back section of the spiral locking section is used for connecting a rotary riveting device. Each spiral tooth is ladder-shaped, the frontal slope is larger than the slope of the lower back, and therefore rivet connecting strength is enhanced and riveting is improved. Tooth form is thin, height of the tooth is lower, and therefore riveting resistance is reduced and service life of a riveting tool is prolonged. The lantern ring is composed of a transformative sleeve and a hexagonal flange plate, and further is provided with a latch and a protruding line which are easy to install. The spiral locking section combines two functions of locking and pulling, and the spiral locking section without snap grooves uses the same tooth forms and sizes, and therefore process is simplified and processing cost is low. Compared with plain bolt, the minisize rotary pulling rivet is reliable in connection, and good in anti-loose, anti-off and anti-loss properties. Compared with an existing minisize plain pulling rivet, the minisize rotary pulling rivet is not only capable of improving installation environment, but also improving riveting connecting strength of products. Property rate covers from 5.8 degrees to 10.9 degrees. The minisize rotary pulling rivet belongs to double-faced riveting system, and is mainly applied to connections of trains, car trunks and thin plates, especially to fatigue structure joint parts.
Description
(1) technical field:
The utility model small dimension revolves pulling rivet, relates to a kind of small dimension fastening piece.The small dimension fastening piece is mainly used in the connection of train, truck body and thin plate.The riveted joint class (B21J) and the fastening piece class (F16B) that belong to metal machining.
(2) background technique:
At present, existing be fastenedly connected the small dimension fastening piece that industry uses and have two kinds: 1. plain bolt: the plain bolt join strength is low, and under bad working environments, exist loosening and come off, and as easy as rolling off a log losing.2. common small dimension tensioned rivet: because the separating vessel of breaking for riveted joint is arranged on the rivet, will break separating vessel during installation, therefore at first be that noise is installed is excessive, and installation environment is poor.Its two, although common small dimension tensioned rivet is to tighten up with cover annular strain riveted joint, because of the impact of the factors such as structure, tooth form, size design, its join strength is still not high, the highlyest only can reach 8.8 grades.
(3) summary of the invention:
The small dimension that the utility model proposes revolves pulling rivet, solves exactly existing small dimension plain bolt join strength problem low, that easily become flexible and easily lose; The existing common small dimension tensioned rivet installation environment of solution is poor, join strength is not high, is difficult to satisfy the needs that high-performance is fastenedly connected.
Technological scheme is as follows:
Small dimension revolves pulling rivet, is comprised of rivet and the collar; It is characterized in that:
1) rivet has from front to back the ailhead, polished rod, the leading portion that connect in turn be used for cooperating the spiral that is connected being connected with rotary riveting device spiral cutting ferrule with back segment to lock section with collar extruding.2) spiral locking section is formed by spiral trapezoidal tooth form, and axial section shape of each helical tooth is trapezoidal in it, and trapezoidal Attacking Midfielder's ratio of slope low back gradient is large.3) collar is comprised of distortion sleeve and hexagonal flange dish.
When the diameter specifications that above-mentioned small dimension revolves pulling rivet is respectively 6mm, 8mm or three kinds of specifications of 10mm, can select the optimized dimensions of following nine kinds of parameters to be respectively value or the span of table 1 sequence number 1, sequence number 2 or sequence number 3.The mm of table 1 unit
Above-mentioned ailhead can adopt circular flange face or countersunk head.The latch that snaps in spiral locking section when installing can be established in above-mentioned distortion collar rear end.Above-mentioned hexagonal flange panel surface can be established convex line.Above-mentioned small dimension revolves the pulling rivet material can adopt carbon steel, stainless steel or aluminum alloy.
The utility model beneficial effect:
1) to revolve pulling rivet identical with other cold drawn rivet for small dimension, owing to utilize the metal plastic deformation principle to finish connection, compares with plain bolt and is connected reliably, and locking anticreep performance is good.2) owing to selected structure, tooth form and the size (seeing Table 1) etc. optimized, compare with common pulling rivet, improved product riveting intensity, the join strength performance rate is contained 5.8 grades to 10.9 grades, for example in the table 1,6mm and 8mm revolve pulling rivet and reach 5.8 grades, and 10mm revolves pulling rivet has 8.8 grades (to see Table D in 1
2=13.93-14.21) (see Table D in 1 with 10.9 grades
2=14.25-14.49) two kinds of models.3) spiral that adopts is locked section, and namely front end is used for and collar locking, and the rear end is used for the screw-in riveting machine and draws usefulness, and two functions without breaking the groove design, have been simplified manufacturing procedure in conjunction with also adopting identical tooth form and size thus, have reduced processing cost.4) gradient is larger before the tooth form, can effectively strengthen the rivet join strength; The gradient is less behind the tooth form, is conducive to the riveted joint of pulling rivet.Add the helical tooth profile of tooth and can design thinlyyer, the tooth height is lower, can reduce the riveted joint resistance, prolongs Riveting Tool working life.5) ailhead adopts the circular flange face, has strengthened the intensity of ailhead.6) collar hexagonal flange dish is convenient installs, simultaneously that riveting pressure is uniform to the connected piece surface, guarantees that connected piece is not destroyed.7) collar is established latch, is convenient to the front collar of riveted joint beginning and rivet and articulates the location, makes easy for installation.8) collar hexagonal flange panel surface is established convex line, can conveniently detect the distortion of the collar in the riveted joint and the displacement of control riveting machine, the convenient installation.9) material adopts carbon steel, stainless steel or aluminum alloy, can adapt to the installation requirement under the various operating modes.10) small dimension revolves pulling rivet and belongs to two-sided riveting system, is mainly used in structure and connects and other tired structure connection parts.
