Abstract

The invention discloses tapping oil for iron and steel workpieces and a production method for the tapping oil. The tapping oil is prepared from the following raw materials in percentage by mass: 6 to 26 percent of dinonyl naphthalenesulfonic acid barium salt, 1 to 8 percent of sulfurized cotton oil, 1 to 8 percent of hydrogenated paraffin, 1 to 6 percent of sulfurized tri-polybutylene, 1 to 3 percent of oleic acid, 1 to 5 percent of triethanolamine, 0.2 to 0.8 percent of isothiazolinone, 1 to 4 percent of odorless kerosene and the balance of machine oil. The production method comprises the following steps of: adding the machine oil and the odorless kerosene in calculated amount into a reaction kettle, heating to the temperature of between 58 and 62DEG C, starting a stirrer, and controlling the rotation speed to be 60rpm; adding the dinonyl naphthalenesulfonic acid barium salt, the sulfurized cotton oil, the hydrogenated paraffin, the sulfurized tri-polybutylene, the oleic acid, the triethanolamine and the isothiazolinone in calculated amount into the reaction kettle in turn, stirring for 30 minutes after one raw material is added, and continuously stirring for 2 to 4 hours after all raw materials are added; and cooling to room temperature.

Description

Iron and steel parts tapping oil and working method

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 also can prolong the tapping cutting tool work-ing life, reduce cost, satisfy the iron and steel parts tapping oil and the working method of environmental requirement.

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.The oilness of the tapping oil that is used for iron and steel parts is not enough, cooling property is insufficient owing to have now, 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 provides a kind of and can reduce the tapping cutting temperature to greatest extent and cut the work-ing life of exerting oneself, improving tapping cut efficient, the precision that guarantees workpiece and surface quality and can prolong the tapping cutting tool, iron and steel parts tapping oil and the working method that reduces cost, satisfies environmental requirement in order to solve the existing in prior technology technical problem.

Technical solution of the present invention is: a kind of iron and steel parts tapping oil is characterized in that raw materials used

And mass percent is following:

Dinonyl naphthalene sulfonate barium 6 ~ 26%

Sulfuration Oleum Gossypii semen 1 ~ 8%

Hydrowax 1 ~ 8%

Vulcanize three polybutylenes 1 ~ 6%

Oleic acid 1 ~ 3%

Trolamine 1 ~ 5%

RH-893 0.2 ~ 0.8%

Tasteless kerosene 1 ~ 4%

The machinery oil surplus.

A kind of working method of above-mentioned iron and steel parts tapping oil is characterized in that carrying out as follows:

A. machinery oil, the tasteless kerosene with calculated amount joins in the reaction kettle, is heated to 58 ~ 62 ℃, agitator control rotating speed 60 commentaries on classics/min;

B. join the dinonyl naphthalene sulfonate barium of calculated amount, sulfuration Oleum Gossypii semen, hydrowax, sulfuration three polybutylenes, oleic acid, trolamine, RH-893 in the reaction kettle successively again; Whenever add a kind of raw material stirring 30min, stir 2 ~ 4H when whole raw materials add the continued that finishes;

C. reduce to room 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; 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. the present invention has bigger avidity and has stronger chemisorption and physisorption iron and steel; Can form the higher more stable lubricant film of fusing point at steel 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.
