The first wire at the wire inlet end and the first wire at the wire outlet end of the cutting wire mesh can be prevented from being broken; and by adjusting the length of the cutting gaps,the crystal rods of different lengths can be quickly switched to be cut.

PendingCN111619026AImprove flowGood cutting precisionWorking accessoriesFine working devicesRobot handEngineering
The invention provides a double-silicon-rod diamond wire squaring machine comprising a lathe bed extending in the left-right direction. Single-silicon-rod cutting systems are symmetrically arranged onthe left side and the right side of the lathe bed. A feed system and a discharge system are arranged on the front side of the middle portion of the lathe bed. A crystal line detection system used fordetecting silicon rod crystal lines is arranged on the rear side of the middle portion of the lathe bed. A cross slide table system is arranged on the middle portion of the lathe bed and comprises alower slide table system extending in the front-back direction and an upper slide table system extending in the left-right direction. A silicon rod grabbing mechanical hand system used for grabbing silicon rods is installed on the upper slide table system. Two squaring machines share one crystal line detection device and one silicon rod grabbing mechanical hand system, and meanwhile cutting nets of the two squaring machines do not influence each other.
