The guide wheel system is responsible for the transmission and direction change of metal wires in the multi wire cutting machine. The wire speed of the multi wire cutting machine can reach up to 680 m/min, and the corresponding guide wheel speed is nearly 3000 r/min. This requires the guide wheel system to rotate at high speed and flexibly, with small jumping, high reliability, and long service life, to ensure stable tension of the metal wire and overall reliability of the equipment. At the same time, the guide wheel system is all located on one side of the winding box, in a relatively dirty working environment, and the mortar fluid will inevitably adhere to the guide wheel. To ensure the flexibility of the guide wheel rotation, a sealing device must be designed for the guide wheel.
The entire guide wheel system is mainly composed of components such as spacers, guide wheel shafts, guide wheels, pressure covers, bearings, etc. The guide wheel is the embodiment of accuracy in the entire system. The metal wire moves at high speed in the guide wheel groove, driving the guide wheel system to move at high speed. The rotational accuracy of the guide wheel reflects the accuracy of the entire system. Therefore, the entire system must ensure the rotational accuracy of the guide wheel after installation, including rotational flexibility, end jumping, and radial jumping accuracy. The high-precision angular contact ball bearings used back-to-back ensure the rotational accuracy of the guide wheel system, making it high-precision and long-life, Small end jumps and radial jumps.
