Abstract
The utility model relating to a wiredrawing rivet could be used in vocations of plane, watercraft manufacture, container, automotive industry, structural steel structure, and high-low voltage transformation tank or the like. The rivet formed by a nail core, a rivet form, a straight wire, a ring groove, a nail core hole, a rivet form cap, and a ring groove is characterized in that root part of the joint between the nail core and the rivet form is provided with a shrinkage knot, inner of the joint provided with a keeper trough and a severing force trough. The utility model has the advantage that the rivet ensures the high strengthened tightness property of the whole riveting craftwork and avoids the nail head revealing out namely the burr and bad riveting phenomena.
Description
Technical field
The utility model relates to a kind of Maolock, can be used for industries such as aircraft, shipbuilding, shipping container, automotive industry, construction steel structure, high low pressure power transformation cabinet, belongs to the rivet technology field.
Background technique
Rivet is widely used in all trades and professions; the nail cored structure of conventional rivet is an elongate rod, and this structure is difficult to guarantee the position of fracture surface and the variation of fastening strength, so the regular meeting mountain shows ailhead and exposes burr and the not tight situation of pulling force in the riveted joint process time; scrappage is high, even reaches 50%.
Summary of the invention
The purpose of this utility model is that a kind of energy of invention improves the tensile strength of fastened workpiece and the Maolock of shearing strength.
For realizing above purpose, the technical solution of the utility model provides a kind of Maolock, form by nail core, rivet body, raw silk rings, annular groove, nail core hole, rivet body top, annular groove, it is characterized in that, be equipped with the contraction joint at nail core and rivet body joint root, be equipped with locking slot, disconnected power groove at nail core and the inside, rivet body joint.
Described contraction joint taper angle is 25 °-30 °, and the tapering root is 1.5mm-2mm with the distance in nail core hole.
Gap between described nail core and the rivet body is 0.4mm-0.6mm.
Described rivet body top thickness degree is 2-3mm.
The material of described nail core and rivet body is stainless steel or titanium alloy.
Owing to be equipped with in nail core and rivet body joint, top and shrink joint, be equipped with rivet body joint root and shrink joint, inside rivet body, make the fracture surface smoother of rivet when guaranteeing the rivet fracture.And rivet bar adopts stainless steel or titanium alloy, improved the tensile strength and the shearing strength of fastened workpiece.
The utility model has the advantages that having guaranteed the high-intensity fastening performance of whole riveting process and having avoided ailhead to expose is burr and bad riveting phenomenon.
Description of drawings
Fig. 1 is the Maolock structural representation;
Fig. 2 is Maolock A place enlarged view;
Fig. 3 is Maolock B, C place enlarged view.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, for being the Maolock structural representation, form by nail core 1, rivet body 2, raw silk rings 3, annular groove 4, nail core hole 5, contraction joint 6, locking slot 7, disconnected power groove 8, rivet body top 9, annular groove 10.
Select for use stainless steel material to make rod member earlier, produce nail core 1 pushing away to pull out on the stretcher again, push away and pull out stretcher and apply for utility model patent simultaneously, shrinking joint 6 conicity angles alpha is 25 °, the tapering root is 1.5mm with the distance A in nail core hole, processing raw silk rings 3, annular groove 4, locking slot 7 and disconnected power groove 8 on nail core 1.
Select for use stainless steel material to produce rivet body 2, the gap B between the endoporus of rivet body 2 and the nail core 1 is 0.4mm, and the thickness C on the rivet body top 9 on the rivet body 2 is 2mm.
Finish by the Riveting Tool pneumatic gun during riveted joint, when pneumatic gun is withstood rivet body top 9, tighten annular groove 4 simultaneously, under the leading role of raw silk rings 3, nail core 1 along the longitudinal backward stretches, because rivet body pushes up 9 one and is withstood by pneumatic gun, rivet body 2 roots have a cone, make nail core 1 draw motionless, thereby make rivet body 2 played drum distortion generation extruding by riveted joint workpiece endoporus, rivet body 2 inwalls are close to firmly follow closely core 1 and, be embedded in locking in the locking slot 7 simultaneously by riveted joint workpiece bore area, and in disconnected power groove 8 sections generation fracture, finally make nail core 1, rivet body 2 is one with being become trisome by riveted joint workpiece mutual extrusion, finish riveting process, because fracture is in rivet body 2 the insides, so guarantee the fracture surface smoother of rivet.
