Circular sawing machine of electric driving for cutting plate

In the present invention， the protrusion height of the circular saw from the upper surface of the mounting plate can be easily adjusted according to the thickness of the plate or timber to be cut， and the circular saw is erected at a right angle with respect to the upper surface of the mounting plate to the side. By allowing you to adjust the inclination within the angle range of 45° so that the cutting angle of the plate or timber can be adjusted， the convenience of use can be maximized， while separate safety on the upper part of the circular saw protruding from the top of the mounting plate. A new electric circular saw device for cutting plate materials is disclosed so that the cover member is detachably coupled to prevent safety accidents caused by sharp circular saw blades during work. The present invention includes a mounting plate having a through hole formed on an upper surface in a direction coincident with the cutting direction of the plate material; A housing disposed at a lower portion of the mounting plate vertically below the through hole， pivotally hinged to the left and right bottom surfaces of the mounting plate， and having an open top; A side plate that is erected and installed in a state spaced apart from a side portion of the housing at a predetermined distance from the lower side of the mounting plate; An electric motor installed in a horizontal direction from the outside of the housing and driven according to the application of current; An operation switch installed on one side of the side plate and controlling driving of the electric motor when cutting the plate material in a state that is electrically connected to the electric motor and an external power source; In a state disposed inside the housing corresponding to the vertical bottom of the through hole， the upper part is installed to protrude from the upper and outside of the through hole on the mounting plate， and the motor shaft of the electric motor is fixedly coupled to the center of the electric motor. A circular saw for cutting the plate material placed on the mounting plate while rotating in place according to the driving direction; A circular saw lifting member installed between the electric motor and the mounting plate and the side plate to lift the electric motor and the circular saw in the vertical direction according to the thickness of the plate material; A circular saw angle adjusting member installed on the housing and the side plate to adjust the inclination of the circular saw within a 45° angle range from a vertically erected state according to the cutting angle of the plate material; A safety cover member that prevents the operator from being injured by the circular saw that rotates while being lifted upward by the thickness of the plate material when cutting the plate while it is installed on the upper part of the circular saw protruding from the upper part of the through hole on the mounting plate. It consists of including.
