Description
technical field
The present invention relates to a kind of the novel vibrating transfer mode and the device that ultrasonic vibration are applied to rolling screw-threads strengthening.Ultrasonic vibration rolling screw-threads technology is on the basis of regular screw threads rolling technology, applies ultrasonic vibration, make the high energy screw thread reinforcement technique rolled in vibration limit, rolling wheel limit to rolling wheel.The connection of rolling wheel and ultrasonic transducer, the mode that is installed seem particularly important in ultrasonic vibration rolling screw-threads technology.Its key is in the efficient transmission ensureing to guarantee again while rolling tool normally works ultrasonic energy.The present invention is that ultrasonic vibration rolling screw-threads technology and the large ultrasonic biography of load are shaken and provided a kind of new approaches and method.
Background technology
Being threaded is a kind of important connected mode, extensive use in aviation assembling and oil drilling etc.And the self structure characteristic of screw thread determines it has the high factor of stress concentration, easily crack at screw thread tooth base position under high frequency complex load, finally cause fatigue failure.Conventional machining easily produces the blemish such as knife mark and cut at Bottom of Thread position, and this region becomes the main contributor of fatigue crack initiation and expansion, greatly reduces the overall fatigue behaviour of component.
For improving the screw product life-span, usually adopting at the bottom of regular screw threads rolling technology double thread tooth and carrying out local strengthening, and obtain certain effect in the strengthening of common material screw thread.Along with a large amount of uses of the Materials with High Strength such as A100 steel, the screw thread strengthening problem of Materials with High Strength seems particularly outstanding.The high powerful feature of Materials with High Strength, makes common rolling technology be difficult to make it produce enough plastic deformations, therefore very limited to the improvement degree of fatigue behaviour.Ultrasonic vibration extrusion process is a kind of high energy reinforcement technique, and the high-frequency impulse characteristic that it has can refinement textura epidermoidea, introduces larger surface residual stress, therefore effectively can improve the fatigue life of test specimen.In ultrasonic burnishing technique, connection and the mode that is installed of rolling tool and ultrasonic wave generation transducer are very important, the normal work of cutter should be guaranteed, need again to ensure that transfer of ultrasonic energy is to rolling tool, while also to consider the problems such as the wearing and tearing of cutter and transducer and service life.Given this, novel vibrating transfer device ultrasonic vibration being applied to rolling screw-threads strengthening has been invented.
Summary of the invention
The object of this invention is to provide a kind of the novel vibrating transfer mode and the device that ultrasonic vibration are applied to rolling screw-threads strengthening, combine the factors such as ultrasonic wave transmission efficiency, high capacity, high-wearing feature and service life, ultrasonic energy well can be transmitted between transducer and rolling tool, play an important role in reinforcement process.
A kind of ultrasonic vibration rolling screw-threads of the present invention intensifying device, comprises ultrasonic transformer 1, rolling wheel 2, door 3, screw 4 and abrasionproof lining 5; Ultrasonic transformer 1 is cylindric part, and front end face is provided with wheel draw-in groove 11 and 4 screwed holes 12; Rolling wheel 2 is wheel shaft one carbide alloy wheel, is squeezing knife tool; Door 3 is disc-shaped parts, above has 4 through holes 31 and square hole 32.Being installed that square hole 32 is wheel provides space; Door 3 is fastenedly connected by the screwed hole 12 that screw 4 is connected on ultrasonic transformer 1 by through hole 31, and abrasionproof lining 5 is enclosed within the axle of rolling wheel wheel 2, is arranged in the wheel draw-in groove 11 of ultrasonic transformer 1.Abrasionproof lining is wear-resisting and material with greater hardness, and its effect is the wearing and tearing preventing ultrasonic transformer.
Ultrasonic wave is sent by transducer, and in ultrasonic transformer front end, amplitude is maximum, passes to rolling tool by the supporting surface of wheel draw-in groove and roll extrusion wheel shaft, and abrasionproof lining therebetween does not affect the transmission of vibration.And the ultrasonic wave energy of elliptical vibration reduces the friction between rolling wheel and lining, improve rolling technology effect, reduce the wearing and tearing of rolling wheel.
Advantage of the present invention and effect are:
(1) rolling tool is that arbor wheel is one-piece type, and transducer supports rolling wheel two ends, increases contact area, and ultrasonic wave transmission effect is better, can realize large load biography and shake, and pass the good stability that shakes;
(2) abrasionproof lining can reduce the wearing and tearing of transducer, and does not affect the transmission of ultrasonic energy;
(3) transmission of vibration guaranteed by screws clamp abrasionproof lining;
(4) elliptical vibration ultrasonic wave can reduce the wearing and tearing of cutter shaft, increases the service life of rolling wheel.
