We can combine the diameter of the wire in and out of the wire to obtain the total compression ratio and partial compression ratio of the straight wire drawing machine, and adjust the partial compression rate according to the process requirements, and then calculate the wire diameter of each drawing channel, according to the second. The principle of equal flow rate is used to derive the drawing speed of each pass of the straight-through wire drawing machine.
Then, according to the empirical formula, the wire strength and the drawing force of each drawing pass of the straight-through wire drawing machine are obtained, so that the motor power can be calculated according to the obtained value. We know that the choice of power of the wire drawing machine is directly related to the manufacturing cost and operating cost of the wire drawing machine. The appropriate power is the basic requirement for the equipment.
Therefore, in the design work, we must first determine the compression ratio of the steel wire. According to the conventional partial compression ratio distribution principle, the first pass is smaller, the second pass is larger, and then successively decremented, and the finished pass is the smallest. According to the compression ratio, the wire diameter of each drawing pass can be calculated. Then, according to the compression ratio, the wire diameter of each drawing pass can be calculated. According to the principle of equal flow of each pass of the straight-through wire drawing machine, the speed of each drawing pass is calculated.
