Description

Manufacturing method of wire drawing lubricant {PROCESS FOR THE PREPARATION OF A LUBRICANT}

The present invention relates to a method for drawing a wire, and more particularly, a method for manufacturing a wire drawing lubricant which can improve working conditions and improve lubricating performance in manufacturing a lubricant for reducing friction when drawing a wire. It is about.

As is well known, during the drawing operation of wires in which the metal is rapidly deformed, a lot of heat is generated at the contact surface between the wire and the drawing die while maintaining the compression and friction conditions under severe conditions, and a relatively soft surface of the wire compared to the die. Surface defects, such as a scratch, generate | occur | produce in the inside.

That is, in the contact surface between the wire surface and the die surface is a severe friction state, in order to reduce the friction force generated at this time to supply a lubricant to the surface interface of the wire and the die, the friction between the wire and the die surface by the supplied lubricant States are divided into two types: fluid lubrication and boundary lubrication. The fluid lubrication is a state in which the surface of the wire and the die is indirect contact through the lubricant layer, which is an ideal friction state, but the friction state of the wire and the die surface is caused by the high pressure applied to the two contact surfaces. It is broken and it becomes the boundary lubrication state which mixes fluid lubrication and a non-lubrication state.

Accordingly, pick-up due to breakdown of the boundary lubrication film caused by rapid pressure rise and frictional heat during drawing of the boundary lubrication state, specifically, prevents surface defects of the wire, and reduces friction coefficient and heat of the wire die and the wire contact surface. At the same time, in order to improve the freshness, the lubricant supplied to the contact surface between the wire and the drawing die is different from the lubricant supplying method according to the characteristics of the wire to be drawn, and is largely classified into dry drawing and wet drawing according to the supplying method.

In the dry drawing method, the lubricant is applied to the surface by dropping the lubricant on the surface of the wire at a point on the path of movement of the wire to the drawing die or by depositing the wire through the lubricant before the wire passes through the drawing wire die. The lubricant applied to the surface of the wire by the method of drawing the wire of is not recovered.

However, such a dry drawing method not only contaminates the working environment due to dust and dust, but also increases the cost of lubricating oil because the lubricant is not continuously consumed and recovered.

In contrast, the wet drawing method is a drawing method that can be applied to a method of applying a lubricant to a wire surface by applying a lubricant of dry drawing and applying a relatively high amount of frictional heat. It is a fresh way to apply. In other words, the drawing operation is performed in a state in which both the drawing die and the drawn wire are deposited in a lubricating coolant, which is an aqueous solution in which a wet lubricant is added to water at a constant concentration.

Accordingly, the present invention is to provide a method for producing a wet lubricant used in the wet drawing method, specifically, a method for producing a wire drawing lubricant that can improve the lubrication performance as well as realizing cooling and cleaning properties. The purpose is to provide.

The present invention, in the manufacturing method of the wire drawing lubricant, after putting soap and water and diluting by heating, and then put carbon powder and lime powder here and heating it, and then put flour again here, heating and diluting 1 Tea manufacturing process; Adding a soap and water and diluting the mixture, and then adding a mixture of glutinous rice flour and flour to the mixture and heating it to boil, and then adding waste oil and grease to the mixture and diluting the mixture while heating; The result obtained by the primary manufacturing process and the resultant obtained by the secondary manufacturing process is compounded in a ratio of 4:14, and then heated to prepare a third manufacturing process for producing a wire drawing lubricant.

The present invention can solve the problem of the dry lubricant (that is, the problem of contaminating the working environment due to dust and dust, the problem of raising the cost of the lubricant, etc.), and also the problem of poor cooling and detergency, which is a disadvantage of the wet lubricant Not only can solve the problem, but there is an advantage to improve the lubricating performance of the lubricant.

Hereinafter, a preferred embodiment will be described to specifically describe the present invention. DETAILED DESCRIPTION In the following detailed description, one exemplary embodiment of the present invention will be presented to accomplish the above technical problem. And other embodiments which may be presented by the present invention are replaced by descriptions in the constitution of the present invention.
In the present invention, when manufacturing a wet lubricant by using a composition such as soap, carbon powder, lime powder, wheat flour, glutinous rice flour and waste oil and grease to solve the problem of dry lubricant as well as improve the lubricating performance of the lubricant. To implement a method for producing a wire drawing lubricant.
For this purpose, not only the method of preparing the lubricant should be disclosed in detail, but also the composition ratio for each composition should be presented. In particular, the present invention should be focused on the manufacturing method of the lubricant because of the technical characteristics of the manufacturing method of the lubricant and the composition ratio of each composition is variable at any time will be presented when explaining the following embodiments. Therefore, since the technical features of the present invention in the composition and manufacturing method of the lubricant, the scope of the present invention should not be reduced due to the following composition ratio.

{Example 1}
Primary manufacturing process
First, 445 g of soap and 4.5 L of water are placed in a 20 L container, and heat (preferably 70 ° C.) is diluted with the container. At this time, it is preferable to apply heat until the soap contained in the container is dissolved (that is, about 10 minutes).
Thereafter, 5.5 kg of powdered powder consisting of carbon powder and lime powder was put into the container and heated with a small amount of 4.5 L of water so that bubbles did not flow into the container. Then, the fire applied to the container was turned off and the carbon powder and lime powder were released. Leave on for about 1 hour. At this time, the soap, carbon powder and lime powder plays a role of lubrication.
Next, 670 g of flour and some water are added to the container, and the container is diluted with heating (preferably, about 10 minutes) with a rod while heating to a temperature of 70 ° C. so that they can be diluted. At this time, the flour allows the soap, carbon powder and lime powder to be mixed smoothly.
Second manufacturing process
736 g of soap and 8.8 L of water are added to a 20 L container, which is heated to a temperature of 70 ° C. until the soap dissolves. Then, 445 L of glutinous rice flour and 445 L of flour are kneaded in a little water and put into a container. Preferably, 70 ° C.) and boil for 10 minutes. At this time, the glutinous rice powder to improve the adhesion to the lubricant so that the surface of the wire well buried.
Thereafter, 2 liters of waste oil and 1.7 liters of grease are diluted, then placed in a container and diluted for about 5 minutes while heating to a temperature of 70 ° C. At this time, the waste oil and grease serves to increase the lubricating performance of the lubricant.
3rd manufacturing process
The wire drawing lubricant of the present invention is produced by placing the resultant obtained in the above-described first manufacturing step and the resultant obtained in the second manufacturing step into a container at a ratio of 4:14, and heating it for about 10 minutes.
The wire drawing lubricant produced by the method as described above may improve the cooling and cleaning properties as described above, and in particular, may improve the lubricating performance of the lubricant.
