Multiwire cutting machine and wiring device thereof

Abstract

The invention provides a wiring device of a multiwire cutting machine, which is used for wiring the multiwire cutting machine. The wiring device comprises a first driving main shaft, a second driving main shaft, a third driving main shaft and a fourth driving main shaft, wherein a working mode of a driving motor of at least one driving main shaft is set into a torque control mode; the torque directions of the driving motors are the same as the rotation directions of the driving main shafts, so that the rotation frictions of part of the driving main shafts are counteracted; the torque of each driving motor is set to be less than friction torque of each driving main shaft, so that the friction torque of each driving main shaft is counteracted with the torque set on each driving motor; the torque of each driving motor is less than the friction torque of each driving main shaft, so that each driving main shaft is kept in a static state when wiring is not performed; and outer force can be used for wiring the cutting machine by only counteracting the friction torque of part of the driving main shafts, so that resistance of a roller system during wiring is reduced, the wiring time is shortened, and the wiring speed of the multiwire cutting machine is increased.

Problems solved by technology

When wiring a multi-wire cutting machine, it is necessary to wind a very long metal wire on dozens of rollers. Due to the large number of rollers that need to be wound, the resistance is large, and the pulling of the metal wire cannot drag the entire roller system. Currently, the control The system controls the take-up and pay-off reel and the main reel to rotate slowly and synchronously, and the wire is wound up slowly with the rotation of the reel manually. This method requires two people to carry out the wiring for more than two hours. The wiring speed is slow and requires a lot of labor. , affecting the overall efficiency of the multi-wire cutting machine
