Abstract
The invention relates a portable hydraulic reveting machine, comprising power assembly A and extrusion assembly B. The powder comes from hydraulic cylinder. The extrusion assembly B squeezes the rivet sleeve (8) bore material into locking groove of rivet (9). The portable hydraulic reveting machine has the advantages of simple structure, easy operation and long lifetime. Using high-strength alloy materials possesses the hommization design concept. The reliability and advantage has been proved by engineering practice.
Description
The present invention relates to the special-purpose construction tool of non-disconnectable connection, the especially high-strength rivet connection pair of heavy parts.
The non-disconnectable connection of heavy parts such as rolling stock, engineering machinery, bridge, tower mast and other construction steel structures has been experienced after rivet hot, welding, the high-strength bolt, has welcome high strength riveted joint new technology.The great advantage of high strength riveted joint is that clamping force guarantees, and is shock-resistant, vibration proof.Under long alternate load effect, the high strength riveting parts still can be kept enough clamping forces, never becoming loose, validity, the reliability of assurance linkage function.And, the easy construction of high strength riveting process, cost is not high and well received, is widely used.Practical application of the present invention is exactly an example.High strength riveted joint, how with high strength rivet and the riveting cover that matches, riveting machine is implemented by special-purpose construction tool----.Chinese patent 90217434.7 discloses a kind of technical scheme of hydraulic pressure ring-grooved rivet rifle.This scheme tractive force of hydraulic cylinder,----die sleeve mode is pushed the riveting cover with push rod, and the two is united two into one.The structural member of this patent is more, and it is complicated that mechanism seems, and the sealing imperfection, the reliability that is difficult to the work that guarantees.Especially the special-purpose construction tool that does not have the high strength rivet can't be riveted high strength (〉=8.8 grades), the major diameter (rivet of φ 〉=20mm).
Notice the deficiencies in the prior art, the especially actual requirement of severe duty the present invention proposes new departure of a kind of hand held hydraulic riveting machine, attempt simplified structure, weight reduction (this is the major issue of construction) reduces cost, and fully guarantees its functional reliability and service life.Prove that through reality the present invention has possessed above-mentioned advantage, satisfied the Technology Need that the high strength riveting process enlarges day by day.
Technical solution of the present invention is:
Hand held hydraulic riveting machine mainly is made of Power Component A and compression assemblies B two parts.The effect of compression assemblies B is: extruding riveting cover in the afterbody of catching the high strength rivet, the material that riveting is overlapped endoporus is expressed in the locking slot of high strength rivet.The effect of Power Component A is exactly the extruding force that for this reason provides enough.
Power Component A of the present invention adopts the ultrahigh-pressure hydraulic cylinder to produce tractive force, and it is huge to exert oneself, again control easily.Compression assemblies B has much intention, and is simple and practical, solid and reliable, easy to adjust, can satisfy the construction of the high strength rivet of several specifications simultaneously, adapts to various users' requirement.
Below in conjunction with accompanying drawing, the present invention is elaborated:
Accompanying drawing 1 is hand held hydraulic riveting machine assembling schematic diagram.
One, structure, function declaration
Power Component A is made up of cylinder body (1), the oil cylinder cover (2) of band plunger, hollow piston (3), and its structure and feed-through hydraulic jack are basic identical.In order to alleviate the overall weight of instrument as far as possible, cylinder body (1), oil cylinder cover (2) and piston (3) are by the superstrength alloy manufacturing under assurance design thrust prerequisite.All seals are made by polytetrafluoroethylene (PTFE), guarantee under super-pressure the hydraulic part motion freely, durable in usely do not leak.
Compression assemblies B is by having sleeve (4), spring (5), split type jaw (6), extrusion die (7) to form.Sleeve (4) and extrusion die (7) are connected with oil cylinder cover (2), piston (3) among the Power Component A respectively, and jaw (6) endoporus arc-shaped ring groove matches with nail tail (a).Under the effect of spring (5), the endoporus of jaw (6) and sleeve (4) fits tightly.For making reliable operation, improve useful life, jaw (6) and extrusion die (7) are all made by special alloy steel.After specially treated, make it have very high tensile strength and impact flexibility simultaneously.The compressive plane of extrusion die (7) is a high-wear-resistant alloy, can use for a long time and precision is constant.
Two, operation principle
The nail tail (a) of high strength rivet (9) is penetrated in the jaw (6).Start oil pump, by P mouth input pressure oil, jaw (6) is caught the nail tail (a) of high strength rivet (9) in sleeve (4); Simultaneously piston (3) drives extrusion die (7) and pushes riveting cover (8) forward, riveting cover (8) endoporus material is got in the locking slot (b) of high strength rivet (9), till will following closely tail (a) and breaking from high strength rivet (9).At this moment, high strength rivet (9) and riveting cover (8) " unite two into one ", become a unbreakable single piece.
Engineering practice of the present invention has obtained good result.Rivet with diameter 20mm is an example, clamping force 〉=210kN, and pulling-out force 〉=300kN substantially exceeds external like product.A large amount of high-intensity alloy materials of low-gravity that use have more humanization design concept.
Claims (2)
