Stainless steel tensile crack wrinkle may be tensile oil formula selection is not correct

Stainless steel products with its good corrosion resistance, heat resistance, low temperature resistance and other properties are widely used in tableware, household appliances, machinery manufacturing, building decoration, coal, petrochemical and other fields. With the development of the economy and the improvement of living standards, the application of stainless steel is more and more extensive, and the demand is also growing, and consumers have higher requirements for product beauty and service life.

1. Stainless steel stretching

The elongation of stainless steel is small, the hardness is large, the factory in the process of tensile processing, due to the workpiece and the mold surface relative movement, under the action of a certain pressure will produce adhesion phenomenon, resulting in scratches on the surface of the product and the mold surface "bonding tumor", so that the product surface scratches, wrinkles, cracking, reduce the service life of the mold.

In the face of stainless steel products, pull, pull and crack problems, some factories use general peanut oil, only physical protective film, mold easy to pull. With salad oil, paraffin oil, oil, blended oil viscosity is too large, not only can not solve the problems of pull, strain, tear, but also cause difficulties in later cleaning. Only in the drawing with professional drawing oil, can form an effective lubrication state.

Because the mold continues to heat up, it is necessary to form a chemical reaction film on the surface of the mold and the material to reduce wear, which requires the corresponding anti-wear extreme pressure agent to be added to the stretching oil, otherwise the general Base Oil will break when the temperature rises, and the oil film cannot play the corresponding lubricating protection role.

After changing to a professional stretching oil, there are anti-wear extreme pressure agents, which can form a chemical reaction film very well to protect the mold from strain. The surface finish of the stretched workpiece is very good, but also reduces the frequency of mold repair, improves productivity, and reduces material waste.

2. Formulation properties of stainless steel tensile oil

Stainless steel stretching oil is a combination of a variety of functional additives, is dedicated to stainless steel and alloy steel high depth and high strength extrusion, stretching, stamping processing lubrication oil. Can be used for battery shell, stainless steel pipe, etc.

Performance characteristics:
1. Excellent lubrication performance, can effectively reduce the wear of the mold, extend the life of the mold;
2. High surface finish and good gloss of the workpiece;
3. High oil film strength, excellent extreme pressure performance;
4. Good anti-rust performance to prevent workpiece corrosion;
5. With excellent extreme pressure, it can ensure that under high, deep and difficult processing conditions, effectively improve the quality and processing power of the workpiece, and increase the life of the mold. Can withstand the high temperature caused by metal friction; Tensile forming parts do not crack, do not crack.
6. Easy to clean, save cleaning costs, improve labor efficiency!

Main parameters:
Appearance: yellow viscous liquid;
Kinematic viscosity 40℃ : > 180mm2/s;
Flash point: > 200℃;
PD value: > 7500N

3. How to choose the right stretching oil?

1, high viscosity, to ensure continuous effective oil film thickness, to avoid local scratching or sintering of the mold;
2, with excellent extreme pressure wear resistance, especially designed for high hardness, high toughness stainless steel processing;
3, excellent lubrication performance, make punching sharp incision smooth, reduce mold wear, reduce product burrs, good rust resistance, prevent workpiece corrosion.
4, high lubrication effect, constantly provide efficient lubrication in plastic changes.
