The utility model provides a
metal cast
ingot cold shut and
impurity grinding device which comprises a
machine body and a top
grinding wheel unit installed on the
machine body. The side edge
grinding assemblies are installed on the two sides of the
machine body, and each side edge grinding
assembly comprises a
grinding wheel, a transverse moving mechanism, a lifting mechanism and a hidden groove; the
grinding wheel is installed at the end of the transverse moving mechanism, the transverse moving mechanism is installed at the upper end of the lifting mechanism, the lifting mechanism is installed at the bottom in the hidden groove, and the hidden groove is fixedly connected to the side wall of the machine body. And the
grinding wheel is rotationally mounted in a mounting groove formed in the end part of the transverse moving mechanism and is in transmission connection with a motor I mounted on the transverse moving mechanism through a gear. The grinding device can
grind the top face and the two side faces of the cast
ingot at the same time, the cast
ingot is prevented from being disassembled and assembled multiple times, the disassembling and assembling frequency is reduced, the grinding efficiency of cold shut, impurities and other defects of the cast ingot is improved, and the
machining progress of the cast ingot is accelerated.
