Description
Technical field
The present invention relates to a kind of method for being carried out texturing by ultrasonic wave vibration to surface of workpiece, belong to metal surface texturing technical field.
Background technology
The frosting treatment of metal surface has many effects, as changed surface topography, improving case hardness and wearability, reduces internal stress, reduces and skid, improve its service life.After breaker roll texturing, the steel plate of its rolling can be made to have significantly improve at image clarity, deep drawing quality and the adhesive ability to paint, oil storage and catch metal fragment when being conducive to punch forming, prevents punching press from scratching, guarantee punching parts surface finishing.
The frosting treatment technique on metal current surface mainly contains shot-peening texturing, electric spark texturing and laser roughening etc.Shot-peening texturing, being by beating at surface of workpiece at a high speed by shot-peening sand, making surface of the work produce small hole point or projection, the method is simple and convenient, cost is low, efficiency is high, but is subject to the impact of shot-peening sand grains footpath and impulsive force, makes surface of the work texturing everywhere uneven.Electric spark texturing workpiece and electrode is immersed in the working solution of insulating properties to reach texturing object by electric spark etching surface of workpiece, and the method investment is high, and power consumption is large.Laser roughening adopts high-energy, the negative out of focus of pulse laser beam after focusing of high repetition frequency is irradiated to roller surface and implements preheating and strengthening, focus point after focusing incides roller surface and forms small molten bath, by side-blown device, small molten bath is imposed on to the assist gas of setting pressure and flow simultaneously, make the fused mass in molten bath be stacked into melt pool edge by appointment requirement as far as possible and form arc cam (peak value), " laser roughening machine of laser focusing head array is adopted " and CN101117712 disclosed " roller surface laser roughening and microalloying combined machining method " disclosed in CN021368546, but it is large that laser roughening also exists equipment investment equally, consume energy high problem.Chinese patent literature CN101255593 discloses " a kind of method of metallic material surface texturing process ", is a kind of metal compound particles is placed in electro-deposition basal liquid realize texturing by electro-deposition, operation more complicated.
Ultrasonic technology also has application in frosting treatment, disclosed in CN1326825 " surface micro-pit supersonic making method ", the method adopts individual tool head or matrix tool head or cellular tool heads to apply vibration frequency f > 18kH along friction pair working surface radial direction
zultrasonic vibration, pressure is greater than 6N/cm
2, friction pair working surface Formation Depth consistent 25% ~ 35% micro-hole.According to the explanation of its description, adopt following parameter: f > 18kH
zultrasonic vibration, amplitude 6-28 micron, tool heads diameter 0.01-3.5mm, workpiece rotational frequency is greater than 600 revs/min, and pressure is greater than 6N/cm
2, the tool heads amount of feeding is that 0.1-3mm/ turns, but could form a small amount of micro-hole when cannot form micro-hole during practical application under these parameters or control very strict, operation more complicated.
CN98216830.6 discloses one " apparatus for making micro-pitted surface ", frame is provided with motor, knife bar, motor connects drive through belt pulley and belt, drive eccentric shaft connects with slide block, knife bar one end is provided with slideway and connects with slide block, the knife bar other end is provided with cutter, and knife bar is connected by turning cylinder with frame.This apparatus structure is complicated, complex operation.

Detailed description of the invention
First the ultrasonic texturing head of structure fabrication shown in Fig. 1 and Fig. 2 is pressed, this ultrasonic texturing head comprises supporting seat 2, locating piece 3 and texturing 4, the cavity holding ultrasonic transformer 1 is provided with in supporting seat 2, the front end of supporting seat 2 is provided with the installing hole installing texturing 4, the axis of this installing hole and the axes normal of supporting seat 2, texturing 4 to be arranged in this locating hole and by locating piece 3 axial location.Texturing 4 is in ladder shaft-like, and its end is used for location and installation, and two ends realize axial location by the installing hole of supporting seat 2 front end and locating piece 3.The middle part of texturing 4 is provided with ultrasonic section 5 and texturing section 6, the lateral surface of texturing section 6 can be arc frosted face (namely in cydariform), and also can be the face of cylinder, the external diameter of texturing section 6 be greater than ultrasonic section 5, the lateral surface of texturing section 6 gives prominence to the front end of supporting seat 2, contacts with surface of the work to make texturing section.The lateral surface of texturing section 6 can carry out frosting treatment through laser.As shown in Figures 3 to 6, the arrangement of multiple ultrasonic section 5 and texturing section 6 can be had, three sections of texturing sections 6 and two sections ultrasonic section 5 is provided with in Fig. 3, it is ultrasonic section between adjacent texturing section, two sections of texturing sections 6 and one section ultrasonic section 5 is provided with in Fig. 4, be ultrasonic section between two sections of texturing sections, be all provided with one section of texturing section 6 and one section ultrasonic section 5 in Fig. 5 and Fig. 6, but the texturing section in Fig. 6 be in one end of whole texturing head.As required, more texturing section 6 and ultrasonic section 5 can be set.
Then ultrasonic texturing head is arranged on (disclosed in CN101503755 " a kind of numerical control supersonic machining apparatus for engine lathe ") on ultrasonic metallic surface processing device, CN202079438U disclosed " ultrasonic metallic surface processing device for grinding machine ", CN202072730U disclosed " fast-forward ultrasonic metal surface processing "), make ultrasonic section of the ultrasonic transformer 1 on ultrasonic metallic surface processing device and ultrasonic texturing head to contact.Again ultrasonic metallic surface processing device is arranged on corresponding lathe, by clamping workpiece on machine tool chief axis or workbench, handles lathe and ultrasonic texturing head is contacted with surface of the work, carry out frosting treatment by common Ultrasonic Machining.
During with ultrasonic texturing head directly to surface texturing on workpiece, on the surface topography of texturing 4 and workpiece want texturing to be formed surface topography be inverse relationship, namely surface of the work is the place in micro-hole, texturing 4 shows as projection, so just can process the surface topography required for workpiece.
Such as, when texturing shaft-like workpiece, texturing 4 is installed on ultrasonic metallic surface processing device, and make texturing head and absorption surface, the rotation of texturing head is rotated synchronous with workpiece, namely identical with the linear velocity of workpiece, this point is different from other frosting treatment technique existing, texturing efficiency can be improved like this, simple to operate, do not need to calculate the parameter matched in advance, if avoid laser roughening technique or the unreasonable problem just cannot producing qualified texturing workpiece of ultrasonic texturing technique Selecting parameter.Following parameter can be adopted: 1. changing of workpieces moving-wire speed is greater than 10 ms/min to during shaft-like workpiece texturing process; 2. the texturing head amount of feeding is that 0.03 ~ 6.33mm/ turns; 3. pressure is greater than 6N/cm
2.
When texturing is carried out to sheet metal or workpiece planarization, texturing 4 is installed on ultrasonic metallic surface processing device, and make texturing head and absorption surface, workpiece does feed motion with platen or ultrasonic texturing head does feed motion with crossbeam or main shaft, and it is consistent that this kind of processing mode carries out ultrasonic surface process principle with ultrasonic metallic surface processing device to flat work pieces.
