Abstract
The invention relates to a spirally pressing ring groove rivet, a spirally pressing riveter device and a riveting method, belonging to new fastener. The invention is characterized in that the rivet is composed of a rivet head, a rivet rod and a ferrule, and the rivet rod is composed of a slick rod section, a ring groove section extruded-matched with the lantern ring and an outer thread section. The invention has the advantages of reliability and shock resistance of the rivet and fixation of the ring groove, short rivet rod and saving materials. The pressurizing rivet device is composed of a thrust formed by a gun tip, a connection ring and a nut, and a connector is arranged in the connecting ring hole and into the ring groove of the gun tip. While in rivet, the hydraulic pressure wrench is used to rotate the nut in forward direction, and the nut is driven forward by meshing with the outer thread section, the gun tip is driven forward by force transmission of the front end face of the nut and the back end face of the gun tip, and the lantern ring is extruded out of the ring groove section; the hydraulic pressure wrench rotates the nut reversely, and the gun tip is driven back to be unloaded by the connector in the ring groove. Rotating the nut in forward direction is labor-saving, the inner screw thread is uneasy to be spoiled, and the pull-out of the gun tip is very convenient. The size of the rivet device is small, and impact does not happen during riveting. The invention can be widely used for the fastening connection operated under the condition of anti shock and anti vibration in a narrow installation space.
Description
(1) technical field: spinning ring-grooved rivet of the present invention, spinning riveting machine and clinching method belong to fastening piece class (F16B).
(2) background technique:
For a long time, steel structure such as rail freight, automobile, bridge all use the conventional rivets of rivet hot, the nut that the suitable what of its chemical composition and mechanical property is 4.8 grades, cause that this steel structure connection reliability is low, the repair cycle is short, problems such as later maintenance cost height can't satisfy the requirement of shipping ' heavy duty, speed-raising '.And it is big that pop-rivet is installed labor intensity, and voice is big, befouling environment.Therefore emphasis, the key position at above-mentioned steel structure adopts novel fastener very urgent and necessary.
Chinese patent discloses a kind of novel fastener ' pulling rivet ' (ZL200520035325X, documents 1) the problems referred to above have been solved, produced following effect: 1. installation property is good: with the bolt ratio, needn't apply torque and repeatedly impact, only need just can finish with a riveting machine; Not high to the installation personnel technical requirements, installing only needs the order side to get final product.2. shock resistance is good, and is more solid and reliable than nut, rivet hot or welding; Solved＜alternate load, impacted under the operating mode loosening〉a historic difficult problem, realize being solidly connected forever.3. anti-corrosive properties are strong, the life-span is long: always gapped between internal and external threads during nut connects, and the annular groove of ring-grooved rivet and extruded sleeve interannular are to form by the distortion interlock that a circle circle does not connect, thoroughly eliminate the gap, atmosphere and liquids can't immerse, not corroded by aqueous vapor, improve working life greatly, be specially adapted to need not dismounting and be subject to the sleet attack sites.
Above-mentioned but ' ring-grooved rivet ' exist following deficiency: i. should ' ring-grooved rivet ' separating vessel is arranged and in the rear end long drawing rod, require the riveted joint space big, small space can not adopt this long rivet.Ii. if with existing hydraulic efficiency riveting device, volume is big, also can't realize riveting to small space.Iii. the process of riveting is because of breaking separating vessel, and voice is bigger than normal during installation.Iv. after the riveted joint, the drawing rod of separating vessel rear end is all lost, and waste of material is bigger.
(3) summary of the invention:
Spinning ring-grooved rivet provided by the invention, spinning riveting machine and clinching method, its purpose just provides the circular groove riveting that a kind of ring-grooved rivet had both had the firm protecting against shock of high strength, can be used for narrow and small riveted joint space again.
Its technological scheme is as follows:
Spinning ring-grooved rivet is made up of ailhead 1, nail bar 2 and the collar 3, it is characterized in that following closely bar 2 and is made up of polished rod section 2C foremost, the annular groove section 2A that cooperates with the collar 3 extruding of centre and one section external thread section 2B of rear end.Above-mentioned ailhead 1 can be countersunk head, hexagon head, hexagonal flanged surface head rivet staple head 1.

Rivet the clinching method of above-mentioned spinning ring-grooved rivet with above-mentioned spinning riveting machine, this clinching method of its feature comprises the steps:
I. will follow closely bar 2 and pass and connected two articles 8 and 9, the collar 3 is enclosed within outside the annular groove section 2A, and rifle head 4 is inserted in outside the nail bar, and nut 5.2 screws in external thread section 2B and rotation advances; After packing into a plurality of links 6 in the hole 5.3 of connecting ring 5.1 circumferential arrangement, stretch into again in the annular groove 4.1 of rifle head 4;
Ii. use hydraulic pressure spanner 7 forward turn nuts 5.2, thruster promotes the reach of rifle head by nut front-end face 5.5 and 4.3 power transmissions of rifle head ear end face, and the pushing collar 3 is squeezed in the collar outside the annular groove section 2A;
Iii. hydraulic pressure spanner 7 reverse turn nuts 5.2, the link 6 in annular groove 4.1 retreats with nut and pulls back rifle head 4, and the rifle head retreats and breaks away from the collar 3, thruster and rifle head is taken apart unloaded, and riveted joint is finished.Beneficial effect of the present invention is as follows:
I. spinning ring-grooved rivet is identical with documents 1, has kept circular groove riveting and the shock resistance that has, solid and reliable, corrosion-resistant, premium properties such as the life-span is long.And the nail bar shortens, and requires the riveted joint space little, and Applicable scope enlarges.Ii. rivet has been removed original separating vessel and rear end nail bar, and the nail bar shortens, and material saves about 40%.Iii. adopt spinning riveting machine, its size is approaching with rivet, and the bodily form is little, can be used for narrow and small installing space.As Figure 12, the spinning ring-grooved rivet M that installs in the vibration mechine, the riveted joint space W is very narrow and small among the figure, can't put into existing hydraulic efficiency riveting device.Only need during riveted joint can finish with an existing hydraulic pressure spanner in market.Iv. spinning riveting machine adopts rifle head and thruster split, and establishes annular groove and produce the slide relative mode and connect, and compares with the integrated type spinning riveting machine of hypothesis, and forward turn nut is laborsaving, and internal thread is not fragile; And oppositely can just the rifle head 4 that presses with the collar can be pulled out easily backward by annular groove interconnecting piece 6 during the turn nut.V. spinning riveting machine riveted joint process need not be broken separating vessel is not had impact, and it is little that the ground voice is installed, and environmental protection is good.
It is narrow and small to be widely used in installing space, and that need move under the anti shock and vibration operating mode is fastenedly connected.
