Control of drawing quality of inverted wire drawing machine

Oct 08, 2018

In order to ensure the quality of the drawing, it is also necessary to ensure good control during the operation of the inverted wire drawing machine. The first is to ensure the quality of wire drawing lubrication, because the temperature, concentration and cleanliness of the lubricant have a great influence on the stretching. If the temperature is too high, the heat generated when the metal wire is stretched is not easily taken away, and the temperature of the metal wire and the mold is raised, and the wire is easily oxidized and discolored.


It also affects the service life of the inverted wire drawing machine and will result in a decrease in lubrication. Conversely, if the temperature is too low, the viscosity rises, which is not conducive to stretching. Therefore, the lubricating fluid should be controlled at a certain temperature when the equipment is pulled. Generally, various lubricant concentrations are prepared according to the process requirements to ensure sufficient lubrication of the wire.


In addition, it is necessary to follow the correct matching principle. In this way, in the process of operating the inverted wire drawing machine, the plasticity of the metal can be fully utilized, and the minimum drawing pass can be used to improve the production efficiency; The safety factor reduces the pull-off and the thinning phenomenon.https://www.chinawiredrawingmachine.com/
