Abstract
The utility model relates to a small size drawn rivet, pertaining to a novel cold drawn rivet, which solves the shortages that the existing small size nuts and bolts is easy to be lost when used to connect, clamping force of the small size hot rivet is small and is inconvenient to use. The utility model consists of a rivet head, a rivet bar and a casing ring; the rivet bar comprises a main bar, a pull bar and a separation groove; the main bar is provided with a section of main ring groove section which is drawn, thus closely matching with the casing ring. The small-size drawn rivet has good seismic performance, which is more sable and reliable than bolts and welding. After connected, parts are occluded with no clearance, deformation, gas and liquid incursion, thus preventing bolts clearance from corrosion. The clamping and installation are highly unified, requiring no personal skill or tool accuracy, avoiding torque or multiple impacts with low noise. Therefore, the utility model meets operating requirements in special environments, such as the environment than can not use fire. The patent provides four kinds of small size drawn rivets and casing rings, which has been theoretically and practically tested, ensuring the riveted objects to be tightly connection.
Description
(1) technical field:
This patent relates to a kind of novel pulling rivet.Belong to small dimension and connect fastening piece (F16B).The scope of the label diameter D of rivet is at 5-10mm.
(2) background technique:
When being connected object with small dimension link connection two, then, very little again if adopt the nut nut connection of small dimension because the nut nut is to live in connecting, hold very much by free-hand dismounting, be used in the place that other need connect then, lose thereby cause.If adopt small dimension rivet hot nail to connect, following defective arranged: 1. make and the installation process befouling environment.2. can not be used for particular surroundings, if any fiery part.3. using process has a lot of inconvenience.4. the clamping force after the riveted joint is less.
(3) summary of the invention:
The small dimension pulling rivet that the utility model proposes overcomes defectives such as existing small dimension nut nut connection is easily lost, the little use inconvenience of small dimension rivet hot nail clamping force exactly.Its technological scheme is as follows:
The small dimension pulling rivet, form by ailhead 1, nail bar 2 with the collar 3 that cooperates of nail bar, the nail bar comprises mobile jib 2.1, drawing rod 2.2 and connects both and separating vessel 2.4 betwixt, one section major ring groove section 2.3 that cooperates with the collar 3 pultrusions is arranged on the mobile jib, the label diameter D that it is characterized in that four kinds of small dimension pulling rivets is 5,6,8,10mm, selects corresponding little staking ailing bar outer diameter D 2, ailhead outer diameter D 1, ailhead length L
1Be respectively a group of sequence number 1～4 in the table 1 with the span of the collar inside diameter D 3.1 of the little collar, collar outer diameter D 3.2, promptly value is the number range of sequence number 1 or 2 or 3 or 4; Table 1 (millimeter)
The utility model beneficial effect:
I. the small dimension pulling rivet has good shock resistance, and is more firm more, reliable than nut and welding.Ii. realize that parts connect the no atmosphere in back or liquids is invaded, because of nail bar and cover interannular joint are to form by the distortion interlock that a circle circle does not connect, thoroughly eliminated the gap, atmosphere or liquids can't be invaded.And always have the gap between the nut connection internal and external threads, atmosphere is invaded with liquids cause the screw thread burn into to be connected inefficacy.Iii. clamping and setting height(from bottom) are unified.Be connected ratio with nut, do not depend on operator's skill during installation or adjust the accuracy of instrument on request, do not need torque or repeatedly impact, noise is low.Iv. satisfied the usage requirement of special environment condition.As: the environment that can not use fire.V. the little rivet that provides in the table 1 and little cover ring size be through theoretical with actual twin check so that rivet object and can be connected fastening.

(5) embodiment:
Embodiment 1:
See Fig. 1, form by ailhead 1, nail bar 2 and the collar 3 in the present embodiment small dimension pulling rivet.The nail bar comprises mobile jib 2.1, drawing rod 2.2 and connects both and separating vessel 2.4 betwixt, one section major ring groove section 2.3 that cooperates with the collar 3 pultrusions is arranged on the mobile jib; Annular groove 2.5 is also arranged on the drawing rod 2.2.Wherein:
The relevant size with the little collar of small dimension pulling rivet sees Table in 1 shown in the sequence number 2: pulling rivet label diameter D is 6mm, nail bar outer diameter D 2=6.45-6.58mm, ailhead outer diameter D 1=12.07-13.34mm, ailhead length L
1=3.45-3.86mm; Collar inside diameter D
3.1=6.50-6.73mm, collar outer diameter D
3.2=10.21-10.39mm.
The assembling of small dimension pulling rivet and clinching method comprise the steps: to see Fig. 1～Fig. 6
1) see Fig. 1, in object 5 one sides, the small dimension pulling rivet is inserted the through hole that passes object 5 and 4, make ailhead 1 be affixed on object 5 surfaces, the collar 3 is loaded on the major ring groove section 2.3 of following closely bar 2 and is close to object 4 surfaces.
2) see Fig. 2, load onto riveting machine 6, riveting machine chuck 6.2 clamps on the annular groove 2.5 of drawing rod 2.2.
3) see Fig. 3, the riveting machine oil cylinder piston moves, and promotes riveting machine overcoat head 6.1 axial advancement, and the extruding collar also is anchored on periphery.
4) see Fig. 4, riveting machine is fastened at major ring groove section 2.3 by head 6.1 with the collar 3, clamps drawing rod 2.2 by chuck 6.2, and applies axial tension to pull bar 2.
5) see Fig. 5, nail bar 2 separating vessels 2.4 places disconnect, and drawing rod 2.2 falls by riveting machine and spues; Take off riveting machine, finish the cold drawn riveted joint of small dimension pulling rivet.
Embodiment 2: see Fig. 1
The relevant size with the little collar of small dimension pulling rivet sees Table in 1 shown in the sequence number 4: pulling rivet label diameter D is 10mm.Nail bar outer diameter D
