Abstract
The utility model relates to a self-drilling and self-plugging rivet, which is an anomalous fastener comprising a hollow rivet and a loose core rod which has a drill bit. The utility model is characterized in that the loose core rod and the drill bit are of a low-carbon steel integration moulded structure with no welding. The end of a barb is arranged on the end of the loose core rod. The structures such as a polished rod, a necking, a loose core rod positioning corner, etc. are arranged on the middle part of the loose core rod. Two main cutting edges are symmetrically arranged on the drill bit portion, and the basic body surface layer from the drill bit to the necking of the loose core rod is of a hardening layer. A rivet fixed groove matched with the loose core rod positioning corner is arranged in the hollow inner diameter of the hollow rivet. The utility model can accomplish the drill hole riveting process in one time.
Description
The utility model relates to a kind of from the special-shaped fastening piece of drilled drawing-core bar tubular-shank rivet, and the working continuously of riveted joint that be specially adapted to punch once finished the operation process.
Before the utility model, bore tubular-shank rivet Swede patent applied for certainly, number of patent application is 90102692.1, though this device can satisfy the manufacturing process of boring riveted joint, still has the many places deficiency.One, this drill bit are with Drill Steel or powdered metallurgical material manufacturing, and cost is higher, the manufacturing process complexity.Two, the drill bit manufacturing finishes and also will weld, peg graft, be bonded on the expansion pin, and assembly process increases, cost up.Three, the end of its expansion pin and riveting gun connecting part are polished rods, are not easy to deficiencys such as chucking.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, design a kind of drill bit and core_pulling pole be convenient to one-time formed, need not weld or sticking by drill bit, connect reliable core_pulling pole with riveting gun, tubular-shank rivet endoporus and core_pulling pole connect the form that adopts annular knurl to press-fit, be convenient to tubular-shank rivet and the core_pulling pole form and position tolerance is little, consistent with one heart, it is whole more reasonable from boring the self-plugging rivet apparatus structure to make, and technology is easier, cost is lower, boring and riveted joint more excellent performance.
The utility model is achieved in that this self-plugging rivet of being made up of tubular-shank rivet and the core_pulling pole that has drill bit of brill certainly.Its structure characteristic is that core_pulling pole is to be made of five different structure positions, the end is provided with the core_pulling pole termination that has hangnail of the chucking of being convenient to contact with riveting gun, the top at position, core_pulling pole termination is core_pulling pole polished rod position, the top at core_pulling pole polished rod position, be provided with the core_pulling pole positioning edge, the core_pulling pole positioning edge cooperates the location with the rivet fixed groove of rivet endoporus, the top at core_pulling pole positioning edge position is provided with drill bit, the neutral position that is positioned at core_pulling pole positioning edge position is provided with necking down, it is that tapering transition connects that core_pulling pole positioning edge position is connected with drill bit, from the core_pulling pole termination to whole drill bit, the core_pulling pole that promptly has drill bit is the integrative-structure that does not have welding, be provided with the rivet fixed groove with the tubular-shank rivet endoporus of core_pulling pole assembling, the major part end endoporus of rivet is provided with the rivet cone-shaped inner hole, the core_pulling pole that has drill bit places the tubular-shank rivet endoporus, the core_pulling pole positioning edge cooperates assembling with rivet endoporus fixed groove, rivet rotates with drill bit, the core_pulling pole of pulling back, drill bit places in rivet microcephaly hollow, the rivet microcephaly rivet clasp that expands, core_pulling pole breaks from the necking down position; The core_pulling pole that has drill bit adopts the compression molding of low carbon steel Integratively, takes out drill bit on the core bar to the necking segment position, and the surface of matrix is provided with quench-hardened case, and this laser quenching hardened layer can be a carburized case, nitriding layer, or carbonitrided case; For the ease of compression molding with help drilling speed and precision, bit part is symmetrical arranged two major cutting edges, and its relief angle is 8-10 °, and anterior angle 2-4 °, 118 ° of point angles, 2-3 ° of drill bit reversed cone angle, chisel edge 0.05-0.10 millimeter.Be convenient to compression molding like this and guarantee drilling speed and precision; The number of the rivet fixed groove of core_pulling pole positioning edge and tubular-shank rivet endoporus is more than 4, to guarantee the concentricity of rivet and core_pulling pole, is convenient to assembling; Tubular-shank rivet adopts aluminum alloy or light metal manufacturing, is convenient to riveted joint.
The utility model has reached design purpose, compare with original technology, the core_pulling pole of band drill bit can be once molding formed, simplified manufacturing process, reduced cost of production, its drill bit adopts low carbon steel carburizing or nitriding quench-hardened case, than adopting bit tool steel or powder metallurgy, saved the more expensive material of price, economized on the use of funds, another has reduced cost, the core_pulling pole termination is provided with the termination of band hangnail, be convenient to firmly contact, do not slide when loosing core, further guaranteed the reliability of riveting step with riveting gun, connect the rib groove that adopts roll extrusion between tubular-shank rivet endoporus and the core_pulling pole and press-fit connection, be convenient to assembling and guarantee concentricity and positional accuracy, thus, the utility model is the good design of a kind of ideal.
Further describe with enforcement in conjunction with the accompanying drawings:
Accompanying drawing 1 is from boring the overall assembly structure figure of self-plugging rivet
Accompanying drawing 2 is core_pulling pole overall structure figure of band drill bit
Accompanying drawing 3 is that core_pulling pole positioning edge position A-A is to sectional view
Accompanying drawing 4 is that core_pulling pole drill bit B-B is to sectional view
Among the figure:
1, core_pulling pole termination
2, core_pulling pole
3, rivet cone-shaped inner hole
4, tubular-shank rivet
