Band-shaped lubricating material for dry wiredrawing and process for producing same

Abstract

Provided is an innovative belt-shaped lubricating material for dry wiredrawing which not only can be used under severe wiredrawing processing conditions such as those of high temperature / high pressure / high speed as well as conventional powdered or granular lubricants for dry wiredrawing but also can cope with diameter reduction to a wide range of wire diameters ranging from a small diameter to a large diameter and a wide range of linear speeds ranging from a low speed to a high speed, has excellent functionalities such as lubricity, followability, spreadability, adhesiveness, heat resistance, processability, workability, safety, durability and productivity irrespective of a processed shape, is effective in improving work environments and is friendly to the global environment.The belt-shaped lubricating material for dry wiredrawing includes a film containing 10 to 90% by weight of a metal salt of a saturated fatty acid and 10 to 90% by weight of a thermoplastic resin.

Description

TECHNICAL FIELD [0001]The present inventions relates to a belt-shaped lubricating material for dry wiredrawing, which is used for maintaining a stable processing state by preventing seizure due to direct contact between a base material such as a wire material or a rod and a die when the base material is pulled out and reduced in diameter to perform wiredrawing.BACKGROUND ART[0002]Powdered or granular lubricants for dry wiredrawing are commonly used for wiredrawing processing in which a base material such as a large-diameter wire material or rod made of a metal such as iron and steel or a nonferrous metal is pulled out from a hole of a mold steel such as a die, reduced in diameter into a small-diameter wire material or rod, and plastically deformed. Such a lubricant for dry wiredrawing is used in order to prevent a base material and a die from seizing by coming into direct contact with each other, so that sliding is facilitated to maintain a stable processing state.[0003]For example,...

AI Technical Summary

Benefits of technology

The present invention relates to a belt-shaped lubricating material for dry wiredrawing which can be used in high-temperature, high-pressure, and high-speed wiredrawing processing conditions. This lubricating material can cope with a wide range of wire diameters and linear speeds without causing mass consumption or disposal. It exhibits excellent functional effects such as lubricity, followability, spreadability, adhesiveness, heat resistance, processability, and durability. It can be used at the initial time or intermittently to maintain an adequate lubricating film on the surface of the wire material, thus improving production efficiency and cost-effectiveness. The belt-shaped lubricating material is safe, friendly to the global environment, and can be conveniently and efficiently produced. The wiredrawing method using this belt-shaped lubricating material ensures reliable plastic deformation of the processed base material and can be repeated without the necessity of rewinding the lubricating material.

Problems solved by technology

Therefore, the total amount of the remainder is unwillingly discarded.

Since the recent social situation has been shifting to a society taking care of the global environment through reuse of resources, etc., the above-mentioned mass consumption / mass disposal is becoming a problem.

Since the above-mentioned lubricant is powdered or granular, there is the problem of causing deterioration of work environments, health hazards to operators and environmental pollution which result from dust and the like at the time of use.

Further, it is necessary to use properly or adjust the particle shape of the lubricant for dry wiredrawing according to a processed shape, leading to poor efficiency on the operator side and the producer side.
