Background technology
The metal blocks structure of the well-regulated tunnel defect of inner band has very important using value at specific industrial circle.If inside is with the coldplate of Water-cooling circulating groove, with the EGR etc. of oil circuit, this class formation is widely used in the field such as electronics, Aeronautics and Astronautics, and the pressure for high heating position cools fast.At present, the method preparing tunnel hole in bulk metal material mainly contains following several: the first, utilize milling machine to process groove, then form passage with metallic plate capping, welding, welding procedure can select the kinds of processes such as soldering, electron beam welding, Laser Welding, friction stir welding.When selecting soldering processes, local brazing filler metal erosion may be occurred, occur non-seam drainage, and the solder run off can blocking channel.And when selecting other welding manners, although can avoid the shortcoming of soldering, multiple operations such as whole process need groove milling, processing cover plate, capping, welding just can complete, efficiency is not high.The second, metal casting inner void can also adopt core to be shaped, if but oil circuit is elongated, complicated time, core is easily broken, manufacture difficulty, and be difficult to after casting cleaning.The third, foundry goods built-in pipe, shapes pipeline and is preset to casting mould, then cast.The method cost is lower, although substantially can meet cooling requirements, channel flows can be subject to the restriction of copper pipe sectional area, and the gap between copper pipe and matrix needs to fill, larger heat dissipation region can not be formed, the requirement of some heat dissipation structure part cannot be met.Above three aspects are technical problems that the manufacturing process of metal current coldplate faces, the efficiency that employing traditional handicraft prepares metal cooling board is lower, and add the production cost of structural member to a certain extent, eliminate by technological innovation the important topic that these unfavorable factors are these research fields.
Summary of the invention
The object of the invention is to, a kind of method and instrument preparing tunnel defect that a kind of preparation efficiency is higher and cost is low is provided.
The technical scheme solved the problems of the technologies described above is as follows:
The instrument of tunnel defect prepared by a kind of workpiece, this instrument is made up of interlude, shank and friction head, one end and the shank of interlude connect as one, the other end and the friction head of interlude connect as one, the cross section of friction head is in the font of falling T, and friction head is made up of neck and head, and the external diameter of neck is less than the external diameter of head, after interlude and friction head connect as one, between friction head and the axial end of interlude, form an annular groove.
Preferably, the surface of described instrument is coated with face coat at least in part, and described face coat is made up of the composition of following parts by weight: 1 part, the aliphatic acid that the alkoxyl tertiary amine 1 part that chromium nitride 5-10 part, green silicon carbide 3-5 part, boron carbide 3-5 part, iron oxide 2-3 part, phenolic resins 2-5 part, barium sulfate 1-3 part, mica powder 1-2 part, carbon number are 12-18, carbon number are 6-12, carbon number are fatty alcohol 1 part and water 8-10 part of 7-12.
Preferably, the thickness of face coat is 0.05-0.2mm.
Preferably, described interlude is made up of the first cylindrical section, conical section and the second cylindrical section, one end and the shank of the first cylindrical section connect as one, and the other end of the first cylindrical section and one end of conical section connect as one, and the other end of conical section and one end of friction head connect as one.
Prepare the method for tunnel defect, the friction head of the instrument of High Rotation Speed is penetrated on workpiece wall, according to predetermined movement track, fiction stir is carried out to workpiece, friction head and friction of workpiece produce the plasticize that heat makes around friction head, under the pressure effect that friction head produces, inside workpiece material is extruded and is cut and comes off, and is combined with pace when friction head rotates, make surface metal seam, and form continuous print tunnel defect at material internal.
Have employed such scheme, friction head of the present invention, after design, applies the power to workpiece surface flowing to inside workpiece plastifying material, and plastifying material is extruded, and the material extruded will be cut by friction head shoulder and come off.Meanwhile, by regulating rotary speed and the pace of friction head, making to utilize friction head " work " type structure neck to produce friction stir welding to material and connecing effect, making surface metal seam.The technique of hinge structure, its processing technology is for soldering processes, and without the need to passing through multiple operations such as cover plate, capping, welding again, established technology is simplified, and makes working (machining) efficiency obtain raising.Technique opposing metallic cast-internal hole of the present invention adopts core to be shaped, because it carries out fiction stir according to predetermined movement track to workpiece, and during to elongated, complicated path, easily can will process required tunnel on workpiece, owing to there is no core, therefore there is not the cleaning problem of postorder.Technique of the present invention for foundry goods built-in pipe, because in process, it is open type, therefore, instrument and processed tunnel obtain heat radiation adding in process under air cooling effect, there is not the problem that gap needs to fill, therefore, it is possible to meet the requirement of quick heat radiating.
In sum, instrument of the present invention and preparation method, overcoming traditional handicraft, to prepare the efficiency of metal cooling board lower, and add the problem of production cost of structural member to a certain extent.
