Description

Ultra-thin copper foil board water-base stamping stretching oil and working method

Technical field:

The present invention relates to a kind of Sheet Metal Forming Technology with metalworking coolant and working method; Especially a kind of lubricated and cooling performance is good; Can prevent that scratching from appearring in the stamped workpieces surface, corrosion, can guarantee that surface smoothness, degree of cleaning are easy to ultra-thin copper foil board water-base stamping stretching oil and working method to satisfy the direct matching requirements and the demoulding.

Background technology:

Punch process is called plate stamping again, is through mould sheet material to be exerted pressure, and makes it to separate or produce viscous deformation, thereby obtains the method for processing parts of certain size, shape and performance.In the punch process process; Metallic substance produces plasticity shearing strain; As strong friction takes place, then make local generation high temperature and cause " seam " and adhesive wear between shear surface that produces and mold work surface, therefore need use lubricant (punching drawing oil) with the effect of reducing friction, cool; In the hope of form withstand voltage heat-resisting and tough and tensile composite lubricating film in the metallic surface; New life's shear surface and die-face are separated, thereby reach the raising die life, the purpose of steady shear face surface quality.(thickness is that 0.06～0.15mm) copper foil plate (red copper, brass, xantal and berylliumbronze) has particular requirement when carrying out punching stretch because to ultra-thin; And existing punch process is mostly used is the oil base drawing oil, therefore ultra-thin (thickness is that 0.06～0.15mm) copper foil plate exists following problem when carrying out punching stretch:

1. can produce serious adhesion between ultra-thin copper foil board workpiece and the mould and make the demoulding difficulty, can not realize that the beat type works continuously, influence production efficiency;

2. because of behind the ultra-thin copper foil board workpiece punching stretch forming, because its structure can not be carried out the conventional clean in road, back, and existing workpiece surface can not reach the requirement that direct assembling is used;

3. can not carry out the processing of any surface sealing abate behind the ultra-thin copper coin workpiece punching stretch, but the existing antirust variable color phase of workpiece surface is short and have scuffing and microscopic fibers to tear phenomenon.

Summary of the invention:

The present invention is in order to solve the above-mentioned technical problem of existing in prior technology; Provide a kind of lubricated and cooling performance is good; Can prevent that scratching from appearring in the stamped workpieces surface, corrosion, can guarantee that surface smoothness, degree of cleaning are easy to ultra-thin copper foil board water-base stamping stretching oil and working method to satisfy the direct matching requirements and the demoulding.Technical solution of the present invention is: a kind of ultra-thin copper foil board water-base stamping stretching oil, raw materials used and weight percent is following:

A kind of working method of ultra-thin copper foil board water-base stamping stretching oil is characterized in that having the following steps:

A. elder generation dissolves benzotriazole with the industrial alcohols of calculated amount, and is subsequent use;

B. deionized water, phytic acid, Sodium Benzoate, the trolamine with calculated amount adds in the reaction kettle successively, a step gained solution also added wherein again, and agitator is also pressed 360 rev/mins, stirs at normal temperatures 2 hours;

C. stirring adds alizarin assistant, Voranol EP 2001, polyoxyethylene glycol, USP Kosher and RH-893 successively while heating, and temperature was controlled at 50～60 ℃ of continuously stirring 2 hours;

D. reduce to normal temperature.

The present invention compares with prior art, has following advantage:

1. the present invention is a water-base stamping stretching oil, and its cooling performance is good and relative viscosity is low, can not cause the ultra-thin copper foil board workpiece to stick to the phenomenon on the mould; The active group and the copper foil surface of lipid acid that the present invention is contained and alcohols organic cpds react; Hydrocarbon chain in the active group partly has the singularity that is vertically arranged in copper surface simultaneously; With the film of formation rule arrangement, i.e. chemisorbed film and physical adsorption film (also claiming boundary film).Can reduce friction effectively, stop the wearing and tearing of copper foil plate galled spots, not produce the surface microscopic fiber tearing and keep original smooth finish.

2. the present invention possesses the effect of the copper foil plate workpiece surface being carried out powerful cleaning, makes the ultra-thin copper foil board workpiece without the conventional clean in road, back, just can reach the requirement that direct assembling is used.

3. the present invention has the effect of the copper foil plate workpiece surface being carried out the passivation sealing, and its antirust anti-variable color phase can reach more than 6 months.
