Calculation of compression rate of each pass of straight wire drawing machine

Oct 11, 2018

In the process of using a straight-through wire drawing machine, the total compression ratio is generally calculated by combining the diameters of the wire in and out lines. According to the drawing characteristics of the wire and the requirements of the finished product, the average compression ratio is initially set, and the drawing pass of the wire drawing machine is calculated. Then, using the pull true extension method to calculate the compression ratio of each pass, calculate the wire diameter of each draw pass, and derive the pull speed of each pass according to the principle of equal flow of seconds.


The configured motor has an important influence on the production. Usually we combine the empirical formula to calculate the wire strength and drawing force of each drawing line of the straight-through wire drawing machine, and then calculate the motor by the drawing force and the drawing speed. power.


For straight-through wire drawing machines, the quality of the processing will directly affect the final quality of the product. A more reasonable drawing process can effectively improve production efficiency and finished product quality. Reasonable selection of motor power can effectively reduce the power consumption of product enterprises and reduce production costs. Therefore, it is necessary to calculate the compression ratio of each pass to ensure the safe operation of the device.http://www.chinawiredrawingmachine.com/
