Reinforcing steel bar cutting device for building construction

The invention provides a reinforcing steel bar cutting device for building construction. The reinforcing steel bar cutting device comprises a rack, a workbench, a propelling mechanism, a limiting frame, a touch plate, a pressure sensor, an adjusting mechanism, a fixing frame, a lifting frame, a lifting mechanism, a pressing assembly, a knife rest, a cutting assembly, a translation mechanism, a cooling mechanism and a controller. In the working process, the adjusting mechanism adjusts the position of the limiting frame, a plurality of reinforcing steel bars on the workbench are pushed to move through the propelling mechanism, when the pressure sensor detects that the touch plate is abutted by the reinforcing steel bars, the pressure sensor feeds back the information to the controller, and the controller stops the propelling mechanism and starts the lifting mechanism to drive the lifting frame to drive the pressing assembly and the cutting assembly to descend; the reinforcing steel bars are pressed by the press
