Description
Technical field
The utility model relates to a kind of hydraulic ram elongate plunger rod nano surface intensifying device, belongs to field of surface engineering technique.
Background technology
Along with progress of science and technology, each field requires also more and more widely the type of hydro-cylinder.Therefore, the reinforcement modification of cylinder device internal friction secondary surface becomes the problem of a growing interest thus.Surface strengthening is a kind of process method of improving mechanical component and component surface performance, improving fatigue strength and wear resisting property, can also improve corrosion resistance nature sometimes.
In surface strengthening technology, as the enhancement method of mechanical system, main now cold rolling and the shot-peening dual mode of adopting.But, cold rolling or ball blasting method be applied in technical certain restriction that also receives.As the roll extrusion technology, only be applicable to rotary type, the hardness part below 40HRC.And owing to be pressurised into the static load form, bigger for reaching the required pressure of a certain amount of distortion in rolling; And blasting technology is generally used for the not too high part of surface quality requirement.
For hydraulic cylinder piston rod, the mode of its surface strengthening at present mainly is to realize through the mode of quenching.And for elongate plunger rod, thermal treatment can make part deformation usually, changes its size and dimension precision.
Summary of the invention
The utility model provides a kind of hydraulic ram elongate plunger rod nano surface intensifying device, and with its processing slim piston rod outside surface, the surface microstructure that obtains is little, and is highly polished, wear resistance good, can play the effect that the refinement of metal grain is strengthened; Further improve its anti-wear and wear-resistant performance, increase the work-ing life of hydro-cylinder.
The principle of the utility model is to utilize the cold plasticity characteristics of piston rod surface under the normal temperature state; Mechanical energy that utilization ball high-frequency vibration produces and temperature are handled grinding, reinforcement and miniature deformation that piston rod surface carries out abrasive-free a little more than the energy composite energy of the heat energy of room temperature; Make piston rod surface reach better surfaceness, the crystal grain of refinement surface metal produces stress simultaneously on the surface; Improve surface microhardness, strengthen its wear resistance and fatigue lifetime.
The utility model is realized through following technical scheme: a kind of hydraulic ram elongate plunger rod nano surface intensifying device; Comprise lathe module and ultrasonic nano intensifying device; The lathe module comprises horizontal lathe, is installed in the anchor clamps, spray bar and the knife rest that are used for fixing elongate plunger rod on the horizontal lathe; Described ultrasonic nano intensifying device comprises unit, ultrasonic generator, transverter, horn and the ball of the following connection; Transverter is connected with knife rest.
Wherein, the unit in the ultrasonic nano intensifying device is used for regulating the state of hyperacoustic parameter of nano reinforcement process and real-time monitoring ultrasonic machining; Ultrasonic generator is in order to produce frequency at the 30KHz alternating voltage; Transverter converts the 30KHz alternating voltage to the mechanical vibration of 30KHz; Horn becomes the high-frequency vibration of little amplitude the high-frequency vibration of large amplitude; Ball passes to the elongate plunger rod surface with high-frequency vibration and carries out nano reinforcement.In the process of nano reinforcement, elongate plunger rod is by the lathe module drive; Transverter links to each other with knife rest, can moving axially along elongate plunger rod.The lathe module of forming by spray bar, elongate plunger rod, anchor clamps, horizontal lathe and knife rest; In the process of nano reinforcement; Spray bar injects lubricating oil between ball and piston rod; Piston rod is connected with horizontal lathe through anchor clamps, under the driving of horizontal lathe, makes elongate plunger rod according to the parameter rotation of setting.
Working process is: earlier elongate plunger rod is carried out half finish turning; Finish turning after half finish turning finishes is reserved the ultrasonic machining amount according to the difference of parts; Open spray bar, according to the diameter of elongate plunger rod the speed of mainshaft and the knife rest speed of feed of horizontal lathe are set, the startup ultrasonic wave module is carried out the ultrasonic nano intensified process.
The utlity model has following advantage:
1) the utility model is suitable for low rigidity part.When the ball high-frequency vibration; Lean on mechanical energy and temperature to act on piece surface a little more than the heat energy of room temperature; Rather than rather than main depended on pressure; Therefore when part is handled, can not cause the distortion of part because of the effect of mechanical pressure or heat, can realize processing elongate articles and thin-wall part.Owing to be not the effect of leaning on mechanical pressure, therefore can handle harder material, general requirement piece surface hardness was not higher than HRC60 before handling.
2) nano reinforcement.The interaction of ball and piece surface is high frequency (frequency is 30KHZ), macro-energy and effect that amplitude is very little; Cause the miniature deformation of piece surface; The viscous deformation repeatedly of high frequency causes the crystal grain fragmentation; This special viscous deformation mode can make near the grain refining of material surface to nanometer scale, and this makes that the surface grain refinement degree is even more serious and even than other intense plastic strain modes such as ultrasonic impact, mechanical mills.The generation of nanocrystal makes the piece surface microhardness improve 20%～100%, the wear resistance and the fatigue lifetime of having improved piece surface.
3) surface smoothness is high.Utilize the cold plasticity characteristics of metal under the normal temperature state; Carrying out grinding, reinforcement and the miniature deformation of abrasive-free handles; Make the metal parts surface reach better surfaceness requirement; Can make the surface smoothness of parts reach Ra0.01-Ra0.8, the surface of this ultra-smooth has further strengthened its wear resistance.
4) efficient is high.Direct in-situ carries out the ultrasonic nano intensified process behind finish turning on the horizontal lathe, has saved the middle transport process of piston rod, has improved working efficiency.This working method is than using grinding machine processing to economize one times time, and the positioning reference of processing parts is same benchmark simultaneously, and row position tolerance guarantees easily.
