Circular sawing machine for cutting plate

In the present invention， the inclination of the electric circular saw for cutting the plate， etc. placed on the upper surface of the working table can be adjusted within a 45° angle range from the vertically erected state to the upper surface of the mounting plate， but the front and rear of the circular saw By allowing the direction position to be finely adjusted， the plate material can be cut more accurately， and the blade is installed on the motor shaft that transmits the driving force of the motor to the circular saw， so that the saw housing from the rear of the motor cover when the motor is driven. ) A new circular saw device for cutting plate materials is disclosed to create a pleasant working environment by allowing external air to flow into the inside and then discharge it to the lower and outside of the top housing together with sawdust. 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 top housing that is hingedly coupled to the left and right bottom surfaces of the mounting plate in a state disposed under the mounting plate corresponding to the vertical lower portion of the through hole and has an open top; A side plate that is erected and installed in a state spaced apart from a side portion of the housing under one side of the mounting plate; An electric motor installed in the horizontal direction from the outside of the top housing and driven according to the application of current; An operation switch that is installed on one side of the side plate and controls driving of the electric motor when cutting the plate material while being electrically connected to the electric motor and an external power source; The upper part is installed to protrude from the upper and outer sides of the through hole on the mounting plate in the state of being disposed inside the tube housing vertically below the through hole， 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 of; 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; An angle adjusting member installed on the top housing and the side plate to adjust the inclination of the circular saw within an angle range of 45° from the vertically erected state to the side according to the cutting angle of the plate material; Includes a safety cover that prevents the operator from being injured by the circular saw that rotates while being lifted upward by the thickness of the plate 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. In the circular saw device for cutting plate materials， the position of the saw housing in which the circular saw is accommodated is finely adjusted in the front and rear direction by an operation of rotating it in a forward and reverse direction installed at a lower end of a front side of the mounting plate. An adjustment member; It is installed on the front outside of the motor shaft of the electric motor and the top housing to allow external air to flow into the top housing from the rear side of the motor cover according to the driving of the electric motor when cutting the plate material， and then the lower outside of the top housing with sawdust. It is configured to further include a sawdust discharge member to be discharged.
