Abstract

A fine pulling lube cooling emulsified oil of iron-nickel alloy consists of motor oil 56-60wt%, oleic acid 8-12wt%, mersolates 18-22wt%, Turkey red oil 8-12wt%, triethanolamine 4-6wt%, chlorinated paraffin 20-30wt% and bactericide 0.15-0.3wt%. The process is carried out by adding motor oil and chlorinated paraffin into reactor successively, agitating at 600-650/min while heating to 70-80degree, agitating for 1-2hrs, lowering temperature to 40-50degree, adding mersolates and oleic acid into mixed liquid, agitating at 200-300/min for 1-2hrs, lowering to normal temperature, adding triethanolamine, Turkey red oil and bactericide into mixed liquid, and agitating at 200-300/min for 1-2hrs. It can prevent pulling metal from overheat and oxidation coloring and have better finish degree and brightness.

Description

Lubricated cooling emulsified oil of iron-nickel alloy wire fine drawing and production method

Technical field:

The present invention relates to a kind of drawing process with metalworking coolant and production method, especially a kind ofly prevent drawing wire local superheating fracture of wire, oxidation stain and can guarantee finished surface smooth finish, the lubricated cooling emulsified oil of the iron-nickel alloy wire fine drawing that luminance brightness is high and production method.

Background technology:

Drawing process is a kind of typical method for metal working, is under the drawing effect, reduces the sectional area of metal work material by the die hole core, to obtain high precision, the wire rod of best bright finish or a kind of plastic working technique of tubing.In the drawing course of processing,, need metalworking coolant that metallic substance, mould are lubricated, cool off because metal strain produces new surface of friction greatly and constantly.Especially iron-nickel alloy fine drawing technology, it generally is drawing speed with 18～20m/s, with diameter is that the blank material of  4mm is drawn to the filament that diameter is  0.3mm～ 0.5mm, and in so huge extrusion stretching process, lubricating and cooling agent plays crucial effects especially.At present, iron-nickel alloy fine drawing metalworking coolant all is to adopt lubricity oily lubricant preferably, but the problem that but has the bad and cooling performance difference of cleaning performance, to such an extent as to the drawing silk is through after the drawing repeatedly, at drawing silk surface and a large amount of metal powder of core edge, hole bonding, cause frictional coefficient between the two sharply to increase, drawing workpiece surface finish, luminance brightness are sharply reduced, also aggravate wearing and tearing, influence the work-ing life of mould mould; Cooling performance is undesirable in addition, often takes place because wire or mould local superheating and the quality problems of fracture of wire.In addition, because cleaning performance is bad, all will produce detrimentally affect to later process thermal treatment of drawing wire and annealing quality.

Summary of the invention:

The present invention is in order to solve the above-mentioned technical problem of existing in prior technology, to provide a kind of and prevent the overheated fracture of wire of drawing metal, oxidation stain and can guarantee finished surface smooth finish, the lubricated cooling emulsified oil of the iron-nickel alloy wire fine drawing that luminance brightness is high and production method.
