The frame requirements and wire arrangement of the high speed cut to length line
The high speed cut to length line is a kind of electrical process machine. The wire electrode does the high-speed reciprocating motion and the walking speed is 8 ~ 10m/s. The wire electrode can be used repeatedly and the processing speed is high. It is the main type of production and use in our country, and it is the original electrospark wire-electrode cutting processing mode in our country.
The thread feeding mechanism of the high speed cut to length line is mainly composed of the coil holder, wire winding drum and guide wheel. When the accuracy of the thread feeding mechanism drops, the radial run-out and axial movement of the wire winding drum will be caused. The radial run-out of the wire winding drum will reduce the tension of the wire electrode, causing the wire to loose. And the molybdenum wire will break away from the guide wheel groove when it is serious.
The axial movement of the wire winding drum of the high speed cut to length line will make the wire arrangement uneven and produce the fiber folding. The shaft and bearing of wire winding drum often produce clearance due to abrasion, and it is easy to cause the broken wire. So the worn shaft and bearing must be replaced in time. When the wire winding drum is changing the direction, if the high frequency power supply is not cut off, the molybdenum wire will be burnt due to the high temperature in a short time. Therefore, it is necessary to check whether the over travel-limit switch at the end of the wire winding drum is out of order.
During the use of the high speed cut to length line, it is necessary to keep the wire winding drum and guide wheel rotating flexibly. Otherwise, it will cause vibration of the wire transporting system in the process of reciprocating movement. The positive stop at the back end of the wire winding drum must be adjusted so as to avoid the broken wire.The link stopper contacts and rubs the fast moving molybdenum thread, which will be easy to produce the groove and cause the tension fracture,so it also needs to be replaced in time.
