The invention relates to an automatic
cutting and
grinding equipment for low-
carbon steel pipes used for splicing building structure grids, which includes a supporting base plate, a
cutting device, a clamping device, a
grinding device and a fixing device, and a
cutting device is installed on the top of the left end of the supporting base plate , the clamping device is installed on the top of the support base plate, the
grinding device is connected with the middle part of the support base plate, and the fixing device is installed on the top right side of the support base plate. The present invention can solve the existing steel
pipe welding problems that the steel
pipe cannot be firmly fixed when the steel
pipe is
cut, the
cut of the steel pipe after cutting is not neat, the
cut of the steel pipe needs to be manually polished, the grinding effect of the cut of the steel pipe is poor, and the steel pipe needs to be manually polished before
welding. The position of the steel pipe is corrected, and there will be errors in the position of the steel pipe after correction; it can realize the functions of cutting the steel pipe at a
fixed angle, grinding the incision of the cut steel pipe, and accurately splicing the polished steel pipe together.
