Description
Technical field:
The present invention relates to a kind of metal tapping processing and use tapping liquid, especially a kind of can reduce to greatest extent tapping cutting temperature and cutting firmly, improve tapping cut efficient, the precision that guarantees workpiece and surface quality and also can prolong the work-ing life of tapping cutting tool, the alloyed steel work-piece tapping oil that reduces cost, satisfies environmental requirement and working method.
Background technology:
Metal tapping processing provides under the condition of power at lathe exactly; Adopt dedicated tool that metal blank is cut; Making it to obtain all satisfactory internal and external threads workpiece of shape, size, precision and surface quality, is the most common, more a kind of technology of application in the metal cutting processing.In the tapping course of processing, it is main viscous deformation that the tapping cutting lay produces with the slippage after the extruding of the rake face that receives cutter, and the smear metal of tapping simultaneously acts on the rake face with the pressure up to 2~3GPa, and flows out along rake face with higher speed.Friction between cutter and workpiece generates heat can make tapping process zone temperature rise to more than 1000 ℃, and the tapping cutting pressure of threading tool and the contacted point of contact of surface irregularity part can make this place's surface load reach 5000N/mm
2, therefore, in the metal tapping course of processing, just need to use tapping liquid with excellent lubrication property, cooling property and rust-preventing characteristic, cause the melting welding phenomenon of severe local when cutting to prevent tapping.Owing to have now and be used to make large-scale nut with steel alloy (42CrMn, 20CrMnSi, 25CrMnSi; 30CrMnSi, 30CrMnSiA, 40CrMnMo; The oilness of tapping oil materials such as 30CrMnTi) is not enough, cooling property is insufficient, to such an extent as to following phenomenon can occur in the production process:
1. Luo Feng, screw thread position collapse tooth and fall tooth;
2. thread surface is coarse, and smooth finish is low;
3. the phenomenon of forging a knife appears in the cutting edge of threading tool easily, and work-ing life is short.
Summary of the invention:
The present invention is in order to solve the existing in prior technology technical problem, provide a kind of can reduce to greatest extent tapping cutting temperature and cutting firmly, improve tapping cut efficient, the precision that guarantees workpiece and surface quality and can prolong the work-ing life of tapping cutting tool, the alloyed steel work-piece tapping oil that reduces cost, satisfies environmental requirement and working method.
Technical solution of the present invention is: a kind of alloyed steel work-piece tapping oil, it is characterized in that raw materials used and weight percent following:

Different plug azoles quinoline ketone 0.15%.
A kind of working method of alloyed steel work-piece tapping oil is characterized in that carrying out as follows:
A. elder generation joins 5# high-speed engine oil, 20# machinery oil and the acid of sulfuration cotton seed of calculated amount in the reaction kettle successively; Heat to 50~60 ℃ of agitator; Rotating speed by 240 rev/mins stirs; And adding chlorinated paraffin and lead naphthenate successively, continuously stirring cooled the temperature to below 30 ℃ in 2 hours;
B. the sulphur phosphorus fourth octanol zinc salt, 2-6 ditertbutylparacresol, petroleum sodium sulfonate, the different plug azoles quinoline ketone that add calculated amount more successively, continuously stirring continue to be heated to 70~80 ℃ again and stirred 2 hours after 1 hour, shut down;
C. reduce to normal temperature.
The present invention has following advantage:
1. the present invention's work viscosity of having good conduction of heat, significant thermal conductivity, specific heat capacity, vaporization heat and being complementary; Can promptly take away heat in metal cutting from cutter and workpiece; Thereby reduce tapping cutting temperature and cutting effectively firmly; Thereby reduce the thermal distortion of workpiece and threading tool, keep the hardness of threading tool, prevent to collapse the phenomenon of cracking a joke that tooth falls tooth and blade in Luo Feng, the generation of screw thread position;
2. contained slip additive, cooling additive, extreme pressure agent and the oiliness improver of the present invention all contains the polar molecule of q.s; Steel alloy is had bigger avidity and has stronger chemisorption and physisorption; Can form the higher more stable lubricant film of fusing point on steel alloy surface, this tunic not only firmly but also firm, can be resisted the huge friction between threading tool and the workpiece; Thereby reach better lubricant effect; Prolong the work-ing life of cutter, reduced production costs significantly, improved production efficiency; Simultaneously can reduce workpiece surface roughness, improve surface smoothness;
3. violent smoldering do not take place in the present invention in the courses of processing such as High Speed Threading and heavy cut tapping, do not have the hidden danger that causes fire, and be nontoxic to the operator, environmentally safe;
4. the present invention is in long storage or use, especially use in summer not perishable, long quality-guarantee period.
