In order to find out the wear of the wire drawing die in the inverted wire drawing machine in time, some equipments have a set of process control system, which is used to monitor the change of the size of each wire and the size of all the passes, so that the inverted wire drawing machine can be measured. The wear of the wire drawing die is made possible.
The inverted wire drawing machine is equipped with a laser size gauge and a radiant pyrometer so that the wire length can be measured by a pulse counter mounted on a reel. Compared with the error measured by the micrometer, the laser measurement has smaller dimensional error and the calculated value is also more.
As for the amount of wire drawing wear in the inverted wire drawing machine, it is calculated by subtracting the size of the die hole measured before the test, and the wire length here is measured by the length of the die hole for better reflection. The wear of the wire drawing die.
The test proves that the drawing die wear in the inverted wire drawing machine is divided into two aspects: the change of the wear ring and the increase of the size, and the pressure die can reduce the wear and prolong the service life of the wire drawing die, and also contribute to better guarantee. Brushed effect.
