Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a drawing machine, and more particularly to a drawing machine with an oiling device.

[0002]

[Prior art]

 Conventional drawing processes, such as pipe drawing processes, include hot working and cold working, but are usually used to produce pipes that require high precision, high surface gloss, and high mechanical properties. According to the cold drawing method. Prior to cold drawing, a lubricant is applied to the working material, e.g. rods or pipe-making materials such as larger pipes, to reduce and prevent friction and scratches due to friction during processing. It is possible to improve the glossiness of the product surface. Conventionally, a lubricant with a viscosity of about 400 to 600 cSt has been used to lubricate the material for processing so that the adhered lubricating oil will be stably attached to the surface of the material during transportation before being drawn and will not fall off easily. Although the material is immersed in an oil bath, the higher the viscosity of the lubricating oil, the thicker the film that adheres to the material, so the oil film isolates the material from the die during cold drawing. Since they do not come into complete contact with each other, there is a drawback that the roughened surface of the product after the drawing process increases and precision and gloss deteriorate. On the other hand, the working material is usually long rods or tubes, and longer dipping baths have to be used, which is a significant disadvantage for the factory layout and after lubrication. However, there is also a drawback that when the material is transported to the drawing machine, it touches the oil film and makes the film thickness non-uniform, causing poor processing. Note that the cold drawn material has been hot worked once before that, and since the temperature during hot working is high, oxide scale will grow on the surface of the material, and this scale Can be removed by pulling the material through the die during the first drawing process, but if the film thickness of the lubricating oil is too thick on the material, the scale cannot be completely removed, and the scale continues to be polished. There is also the drawback that it takes time and effort to remove the residual scale by pickling or pickling.

[0003]

[Problems to be solved by the device]

 In view of the above-mentioned drawbacks, the present invention has an oiling device provided in a drawing machine, and thinly lubricates the surface of the processing material only immediately before the processing material enters the die of the drawing machine. During processing, the die can completely remove the scale, thus improving the precision and surface gloss of the product, as well as being advantageous in terms of factory layout and processing convenience. The purpose is to provide an extractor with a device.

Then, before entering the die through the tube (44), that is, immediately before the drawing process, the surface of the pipe forming material immediately before being drawn is coated with lubricating oil by pouring it evenly into the pipe forming material. After that, the pipe-making material can be immediately pulled out through the die, so that the lubricating oil only needs to be thinly inserted, and the disadvantages of the conventional thick film can be eliminated. That is, the extractor with an oiling device of the present invention reduces the precision and gloss of the product due to the conventional film being too thick, and the surface quality due to incomplete removal of scale caused by hot working. , Defects such as disadvantages on the factory layout due to having to use longer dipping tanks to lubricate long working materials, or material after lubrication When the oil is transported to the extractor, the oil film can be touched and the film thickness can be made non-uniform to eliminate defects that cause processing defects.
