In general, the saw blade is machined to have an opposite inclination angle at one end of the metal material used for the saw, and the saw blade is required to have a very complicated working condition due to the constant size and spacing of the saw teeth. Accordingly, a dedicated saw blade cutting device is used for cutting the saw teeth of the saw blade to a predetermined size and interval.

However, in the case of the conventional saw blade cutting apparatus, the saw blade is moved to the position of the cutting cutter and the cutting operation is performed. However, since the operator moves the moving blade of the saw blade manually, the operation is troublesome and the size and spacing of the teeth are not constant. And the productivity of the saw blade is lowered.

In order to solve the above problems, as a conventional technique disclosed in Korean Patent Publication No. 473543 (Feb. 17, 2005), a first bolt rod rotated by a first motor moves upward, A supply portion provided with a guide plate on which the workpiece is placed and an end portion of which is vertically arranged so as to thread the hole of the workpiece and which stacks a plurality of the workpieces and a workpiece stacked on the guide plate of the supply portion, A workpiece grasping portion for picking up a state of being adsorbed one by one by an adsorption plate by a first sensor and an upper and a lower transmitter for moving an operation plate having the adsorption plate vertically along a guide rod by a first cylinder, The upper and lower sensors are selectively supplied to the pressure supply pipe to a position recognized by the second sensor and the third sensor in a state where the upper and lower sensors are attached to the moving body A left and right conveying portion that reciprocates along the first guide rail by pressure to move the workpiece from the supplying portion to the machining position; and a control portion that, when the state of the workpiece attracted to the workpiece gripping portion is recognized as a sensor, A left and a right supporting portion which moves the right knuckle by the third cylinder to support the left and right positions with respect to the workpiece; A workpiece support portion for holding the workpiece while the fixture hinged to the workpiece that moves backward by the fourth cylinder is rotated by the fifth cylinder about the hinge axis; With a saw blade having both sides and a chamfer of each saw blade, that is, a saw blade surface having an inclination angle A saw blade machining part for performing the cutting process four times, the saw blade machining part being mounted on the safety plate, the lower end of the saw blade part being fastened to the bolt rod rotated by the motor by screwing and moving left and right along the second guide rail A left and right moving unit for moving a circular arc around the rotational axis of the rear side to form a plurality of saw blades; and a rear end of the saw blade processing unit is fastened to the bolt rod rotated by the motor by screwing the lower end thereof, The saw blade is rotated in the forward and backward directions to move the saw blade in the forward and backward directions while the saw blade is moved in the left and right direction, And a gripper coupled to one side of the workpiece support portion is supported by a fifth cylinder And a workpiece discharge unit for picking up the processed workpiece while rotating around the center of the workpiece and transferring the processed workpiece to the finished article storage unit. Accordingly, a device for processing the workpiece while stably transferring the workpiece is minimized, Is known.

However, in the case of the above-described saw blade machining apparatus, only one tooth of the inclined angle with respect to the teeth having the opposite inclination angle is cut when the cutting operation is performed on the feed saw blade, so that the feeding and feeding processes over the number of times of the saw blade must be repeated There has been a problem that the speed and efficiency of the work are inferior and the accuracy of machining is remarkably deteriorated as the work progresses by switching the cutting direction and angle of the cutting head each time.
