Background technology
In numerically-controlled machine tool, cutter is direct machining tool, and the quality of cutter will have a direct impact on corresponding product Quality.
It is currently known in the market, the usually used material of metal product process tool is wolfram steel, but wolfram steel knife is being processed When metal product, still there is shortcoming, that is, the product processed, have bloom whiten, the bad orders such as white edge, band, bright line it is existing As, and the service life of tungsten carbide tipped tool is usually relatively low, and the service life is not sufficiently stable.
Invention content
The object of the present invention is to provide a kind of metal product processing technology and devices, can solve above-mentioned prior art problem One or more of.
According to an aspect of the invention, there is provided a kind of metal product processing technology comprising following steps:
Stainless steel substrate is selected, punching operation is carried out, obtains metal product embryo material;
Metal product embryo material is clamped using processing unit (plant);
Bloom chamfering operation is carried out to metal product embryo material using cutter, obtains metal product finished product;
In the process for carrying out bloom chamfering operation to metal product embryo material, the cutter used is sintex.
Advantage is due to the cutter of intermetallic composite coating, to use novel sintex, sintex is to use to receive Rice material " zirconium oxide " is process.It is pressed into upper mold with 300 tons of weight under 2000 degree of high temperature with Zirconium oxide powder Cutter blank, then with diamond polishing, mixing handle of a knife has just made finished product sintex later.
Sintex, wearability is good, can process the high hard material that conventional tool is difficult to or cannot process at all, thus Annealing can be exempted and process consumed electric power;And the hardness of workpiece therefore also can be improved, extend the service life of machinery equipment, no It is only capable of carrying out Roughing and fine machining to high hardness material, can also carry out milling, planing, interrupted cut and the impacts such as blank pull-shortage is rough turn The prodigious processing of power.In can be with effective solution metal product, such as mobile fingerprint ring product processing, conventional tool tool The problems such as some metal product white edges, bright line, band.
Small with metal friction power when ceramic tools in cutting, cutting is not easy to be bonded on blade, is not likely to produce built-up edge, in addition It can carry out high-speed cutting.So when condition is identical, workpiece table and roughness ratio is relatively low.The durability of sintex is than tradition High several times even tens times of tungsten carbide tipped tool, reduces the number of changing knife in processing, to ensure to be processed work from side The Small Taper and high-precision of part.Meanwhile sintex primary raw material is the very abundant nitrogen and silicon of nature, and hard tungsten is replaced with it Steel alloy can save the noble metals such as a large amount of W, Co, Ta and Nb.
In some embodiments, sintex is single-point tool, using dextrorotation right cut structure.Advantage is to adopt With single-point tool, there can be better cutting effect that it is white to prevent metal product to ensure the machining accuracy of product The problems such as side, bright line, band.
In some embodiments, sintex includes handle of a knife, blade side wall and blade head, and the angle of blade side wall is 127.9 degree to 128.9 degree, the vertical height of blade side wall is 1.16mm to 1.26mm, and a diameter of 0.99mm on blade head is extremely 1.01mm.Advantage is that using the cutter of the parameter, can there is preferable machining accuracy, while can ensure have again Preferable service life.
In some embodiments, further include step:
It tests to metal product finished product, according to inspection result, corrects the parameter of sintex.Advantage is, Be modified by examining, it is ensured that final products it is more excellent.
The invention also discloses a kind of metal product processing unit (plant)s comprising bottom plate, cover board and symmetrically arranged cylinder, gas The top of cylinder is equipped with gripping block, and the gripping block on symmetrically arranged cylinder is oppositely arranged, and cylinder is fixed on the side of bottom plate along upper, Cover board is covered on bottom plate, and gripping block pushes down the edge of cover board, is equipped with mounting hole on bottom plate and cover board, on bottom plate and cover board Mounting hole is oppositely arranged, and metal product embryo material to be processed is located between bottom plate and cover board.Advantage is to pass through cylinder Contraction, so as to which gripping block is shunk, finally by cover board with bottom plate being pressed together tightly, to by gold to be processed Belong to product embryo material to be located between bottom plate and cover board, easily corresponding metal product may finally be carried out using sintex Processing.
In some embodiments, be provided with cylinder support plate on cylinder, cylinder push-rod pass through cylinder support plate and with folder Tight block is connected, and cylinder support plate is fixed on the side of bottom plate along upper by fastening screw.Advantage is to pass through cylinder branch Board, it may be convenient to cylinder be fixed, and kept in the same plane, to ensure that the clamping to cover board is more stablized.
In some embodiments, bottom plate is equipped with location hole, and cover board is equipped with positioning pin, and positioning pin coordinates with location hole Setting.Advantage is, by the cooperation of location hole and positioning pin, cover board and bottom plate can be allowed to coordinate more stable.
In some embodiments, gripping block is trapezium structure, and gripping block is less than the other end towards one end of cover board.It has Beneficial effect is preferably cover board and bottom plate can be clamped together, while can reserve larger space again, facilitates Stupalox Tool is processed.
In some embodiments, cover board is equipped with fool proof bolt towards excellent power glue-line, bottom plate is covered in the one side of bottom plate, Cover board is equipped with fool proof groove, fool proof bolt and fool proof fit depressions.Advantage is, after being provided with excellent power glue-line, by It is also known as polyurethane PU elastomer in excellent power glue, is a kind of good with intensity, compressive deformation is small.One between plastics and rubber Kind new material, the rigidity with plastics, and have the elasticity of rubber, so metal product to be processed can be fixed, Excessive compression can be prevented again so that metal product to be processed deforms.
In some embodiments, it is set on cylinder support plate there are two cylinder installation station, the side of bottom plate is equipped with two Two cylinders of a cylinder, the same side are mounted on same rest pad.Advantage is that two cylinders can ensure to compress Effect, while two cylinders are arranged on same cylinder support plate, it is ensured that the consistency of two cylinders ensures to clamp Effect.
