Abstract
In a method of working a metal member, a liquid synthetic detergent mainly composed of a surface-active agent is supplied to a metal plate as a lubricant in a press working step of holding the metal plate between a male die and a female die and press-forming the same. According to this working method, press working of a stainless steel plate or the like can be smoothly performed due to excellent lubricity of the surface-active agent contained as the main component in the liquid synthetic detergent. When a lubricant prepared from a liquid synthetic detergent containing a rust preventive is applied to lubrication of a carbon steel plate or the like, excellent workability can be attained without rusting, due to the action of the rust preventive, and with no contamination by oil.
Claims27
A method of working a metal member comprising the following steps:
- supplying an oil-free lubricant consisting of a liquid synthetic detergent that is mainly composed of a surfaceactive agent to a metal plate consisting of a work-hardenable material, and excluding the application of a lubricating oil onto said metal plate;
- and
- press working said metal plate with said oil-free lubricant thereon by holding and press-forming said metal plate between male and female dies to form said metal member.
A method of working a metal member comprising employing a liquid synthetic detergent as an oil-free lubricant and excluding the use of a lubricating oil, while performing working on a corrosion-resistant metal material to form a prescribed metal member.
A method of working a metal member comprising employing an oil-free lubricant comprising a liquid that is mainly composed of a surface-active agent and that further contains polyoxyethylene alkyl ether, alkyl sulfuric ester and fatty acid, and excluding the use of a lubricating oil, while performing working on a plate of stainless steel to form a prescribed metal member.
A method of working a metal member comprising the following steps:
- supplying an oil-free lubricant consisting of a liquid synthetic detergent that is mainly composed of a surface-active agent, and a rust preventive agent to a metal plate, and excluding the application of a lubricating oil onto said metal plate;
- and
- press working said metal plate with said oil-free lubricant thereon by holding and press-forming said metal plate between male and female dies.
A method of working a metal member comprising employing an oil-free liquid containing a liquid synthetic detergent and a rust preventive as an oil-free lubricant and excluding the use of a lubricating oil on a metal material, while performing working on said metal material to form a prescribed metal member.
A method of working a metal member comprising employing an oil-free lubricant comprising a liquid that is mainly composed of a surface-active agent and that further contains polyoxyethylene alkyl ether, alkyl sulfuric ester, fatty acid and a rust preventive agent, and excluding the use of a lubricating oil, while performing working on a metal plate to form a prescribed metal member.
