The machining method includes the steps that a nut with an internal thread is selected; the position, where the internal thread is needed, of the amorphous alloy product is machined to form a straight hole, and the hole diameter of the straight hole is smaller than the outer diameter of the selected nut; the nut and the amorphous alloy product are placed in a jig, and the axis of the nut is consistent with the axis of the straight hole; and the nut is directly pressed into the amorphous alloy product through pressing equipment, and the nut is in interference fit with the machined straight hole. Cost is low in the machining process of the machining method, and the machining method is simple, convenient to implement, and suitable for batch production.
Description
Technical field
The present invention relates to a kind of non-crystaline amorphous metal product female thread machining method, be specifically related to a kind of pressure and nut be pressed into the method obtaining female thread structure in non-crystaline amorphous metal product.
Background technology
Along with the development of non-crystaline amorphous metal application technology, increasing field starts to apply amorphous alloy material.Compare with conventional metal material, non-crystaline amorphous metal has the specific structural features of longrange disorder and shortrange order, thus there is the excellent properties such as high strength, high rigidity, excellent abrasive resistance and corrosion resistance, self-sharpening and higher elastic limit, be one of new structural material of a kind of generally acknowledged most potentiality, future will be widely used in fields such as 3C, medical treatment, sports goods, Aero-Space and military projects.
The non-crystaline amorphous metal product mode of casting that adopts shaping more, and along with the quick application of this material, only rely on the structure cast out can not meet more and more higher needs.In the process being applied to product, propose increasing challenge to the performance of non-crystaline amorphous metal product machining, mode, female thread structure is one of them.Helicitic texture many uses tool sharpening of traditional metal materials and obtaining, but because non-crystaline amorphous metal hardness, intensity, wearability are too high, the methods such as traditional tapping, car tooth cannot be applied in actual production at all, main cause and cutter very easily rupture in processing amorphous alloy material process, cause cost high, be not suitable for the modern production of mass completely.Also have at present and use CNC or other lathes such as milling machine amorphous alloy material to be carried out to the technique of screw thread process, cracking of cutter frequency and cutter changing time can be reduced on a small quantity, can be used for batch production reluctantly, but do like this and can not solve the short-life problem of cutter, cost is remained high.
Application number is that the invention of by name " method that non-crystaline amorphous metal is combined with dissimilar materials and the complex " of 201110237931.X provides a kind of solution: the prefabricated component of dissimilar materials (as nut) and non-crystaline amorphous metal can be put into mould one-body molded, thus the sub-assembly of acquisition amorphous alloy material and dissimilar materials.Application the method not only needs to propose higher requirement to the design processing of mould, and only can carry out just one-step forming, cannot process non-crystaline amorphous metal product.
Summary of the invention
In order to solve described the deficiencies in the prior art, the invention provides a kind of non-crystaline amorphous metal product that makes using any cutter, procedure of processing simple and quick that do not need and there is the processing method of female thread structure.
Technical problem to be solved by this invention is achieved by the following technical programs:
1, female nut is selected.
Further, selected female nut is tape guide platform nut or without guide table nut.Do not affect the press-in of follow-up nut with or without guide table, both differences are, have the nut of guide table more easily accurately can be positioned over the position in non-crystaline amorphous metal Product processing hole, the nut without guide table then needs by tool to aim at the position of machining hole.
Further, selected female nut is round nut, and outer surface annular knurl.
Further, nut outer surfaces annular knurl is straight burr, reticulate pattern or twill.
After nut press-in, the interference fit of nut and machining hole can cause machining hole side face to produce certain deformation, and annular knurl back nut surface can produce gap, after nut press-in, the annular knurl on nut surface then can be out of shape, the deformation that the interference fit just in time can offsetting partial nut and machining hole causes.
2, non-crystaline amorphous metal product needed internal thread place is machined into straight hole, straight hole aperture is less than selected nut external diameter.Straight hole processing can use lathe or CNC, and straight hole can be through hole or blind hole.
Further, preferred straight hole aperture 0.03-0.30mm less of selected nut external diameter.
Straight hole machining accuracy is not as screw thread, therefore straight hole processing is simple, only need meet hole and nut forms interference fit.But, if straight hole aperture again can cause nut pressure more too small than nut external diameter is not entered, or it is comparatively serious to compress into rear deformation of products, it is best that present inventor finds after deliberation by straight hole pore size control in the scope of 0.03-0.30mm less of nut external diameter, both the interference fit after being pressed into can have been ensured, deformation of products is also very little, can not affect integral product quality.
3, nut and non-crystaline amorphous metal product are positioned in tool, nut axis and straight hole axis are consistent, nut axis and straight hole axis are consistent, to guarantee that nut is pressed in straight hole smoothly, there will not be skew to cause the situation that cannot be pressed into.
Described tool is made up of firm banking and briquetting, and both carry out dismountable locking connect by screw thread, buckle, hinge, external securing member; Firm banking be positioned at bottom, on base according to non-crystaline amorphous metal shape of product fluting for placing product, briquetting is positioned at base upper end, and size is identical with base, on briquetting according to product straight hole position correspondence perforate in order to placing nut.
In above-mentioned tool use procedure, product is placed in the product groove of base, builds briquetting, base and briquetting are locked, then nut is put into the position of opening on briquetting.
4, utilize press equipment that nut is directly pressed into non-crystaline amorphous metal interiors of products, make nut be interference fit with processing straight hole.
Further, the press-in pressure of press equipment is 50-1000KN.The selection of press-in pressure is depending on the hardness of non-crystaline amorphous metal product itself and intensity.Press equipment selects commercially available pressing equipment, pressing machine etc. can meet the common equipment of press-in pressure.
Can use that the non-crystaline amorphous metal of the processing method in the present invention is zirconium-base amorphous alloy, Fe-based amorphous alloy, al based amorphous alloy, cu-based amorphous alloys, titanium-based amorphous alloy, ni-based amorphous alloy.
The present invention has following beneficial effect:
1, process is without the need to using the main equipment such as cutter and CNC, greatly reduces cost;
2, processing method is simple and convenient, effectively promotes process velocity and working (machining) efficiency, and suitable batch is produced;
3, process does not comprise direct machining screw, the problem that there will not be machining screw low precision to cause product cannot to use.
