Description

A kind of processing method in screw tap surface industrial titanizing
Technical field
The present invention relates to a kind of processing methods in screw tap surface industrial titanizing.
Background technique
Screw tap is common process tool, application it is extremely wide, existing screw tap processing method be divided into thread forming tap and Cut tap, two kinds of processing methods respectively have feature, and thread forming tap is a kind of advanced chipless forming thread process tool, after processing Accuracy of thread is high, is widely used in the Seiko industry such as automobile, aviation, electronics.Since extrusion forming chipless is interfered, plus Work accuracy of thread may be up to 4H, and thread surface roughness is up to Ra0.3 or so.But it since thread forming tap uses extrusion forming, needs Extruding force is increased, therefore its screw thread process for not being suitable for hard material is used, and cut tap can be applied to hard material Screw thread process, but its precision is not too high, it is therefore desirable to is further improved.
So in order to promote the hardness of screw tap, in order to process screw thread in harder material surface.Silk is often used now The method that poppet surface increases the coat of metal, it is most common exactly to plate one layer of Titanium on the surface of screw tap, and according to atmosphere Difference, it is most commonly seen in the titanium nitride of yellow to be plated under nitrogen environment.But existing industry titanizing mode, overlay coating are thick Degree is uneven, and plating defect is more.
Summary of the invention
The purpose of the present invention is to solve the above the deficiencies in the prior art, propose one kind in screw tap surface industrial titanizing Processing method.
A kind of processing method in screw tap surface industrial titanizing, comprising the following steps:
One, surface polishing;Screw tap surface is processed by shot blasting using polishing cotton, removes dirt and the cutting on screw tap surface Tumor;
Two, electrochemical deoiling;Screw tap surface is cleaned using sodium hydroxide or phosphoric acid, when cleaning a length of 10-25s;
Three, drying is rinsed;Using the bottom of tooling clamping screw tap, using swiftly flowing high temperature dry gas to screw tap Surface is dried up;
Four, vacuum titanizing;First magnetron sputtering apparatus is vacuumized, reinjects argon gas, and gradually heat up;It is passed through nitrogen again, And the plated film that is powered, until screw tap surface layer forms one layer of yellow coating;
Five, it stands;Screw tap is extracted out from magnetron sputtering apparatus, and is placed in rest chamber and stands, it is initial in rest chamber Temperature is maintained at 50-200 DEG C, preferably 80-185 DEG C, then cools down in staged, cools down 10-30 DEG C per hour, until being down to often Temperature further takes out screw tap;
Six, oiling is cleaned;Screw tap surface is purged with air gun, and is placed in the darkroom of the antirust oil full of atomization, oiling Shi Changwei 10-15s;
Seven, it encapsulates;Examine encapsulation.
It preferably, further include that Shot Blasting is carried out to screw tap surface in step 1.
Preferably, the temperature of the high temperature dry gas in step 3 is 200-300 degrees Celsius.
It preferably, further include being cleaned using ultrasonic cleaner to screw tap surface in step 2.
Preferably, the cathode in the magnetron sputtering apparatus is rotating cathode.
The utility model has the advantages that
The application is plated by the way of ti coat on diamond, and in the environment of protective atmosphere is nitrogen on the surface of screw tap One layer of titanium nitride in yellow enhances the surface strength of screw tap with this.
It is dried up by surface polishing, electrochemical deoiling, flushing the high screw tap semi-finished product of surface cleanliness are made, with this with this Guarantee that coating is combined closely with metal layer, centre does not have the uniformity of impurity effect coating, in plating, first uses indifferent gas Body argon gas supports vacuum environment, and is warming up to suitable temperature, and at this time under the protection of argon gas, the metal layer on screw tap surface will not It chemically reacts, then by nitrogen, and under the protection of nitrogen, magnetron sputtering apparatus starts operation, will be in cathode targets Titanium uniformly sputters in a device, and reacts with nitrogen, finally plates the titanium nitride in yellow on the surface of screw tap, plating After, cooling velocity is too fast in order to prevent, leads to coating fragmentation situation, by the way of standing simultaneously ladder cooling, with every small Screw tap is gradually cooling to room temperature by the speed of Shi Jiangwen 10-30 DEG C, guarantees the uniformity of coating, to realize the surface work of screw tap Industry titanizing.
