  In the case of manual scissors, the operator needs to move the scissors at a cutting speed required for cutting the scissors blade while pressing the scissors with a predetermined force, and therefore requires a large amount of labor and a predetermined skill.

  In the case of an electric kite, in order to obtain a predetermined surface accuracy, the rotor must be rotated at a high speed, which requires a large amount of power. Since the chips are finely cut, dust is generated and high noise is generated. The blade is dangerous because it rotates at high speed.

  With a reed that moves the reed blade back and forth, the work material can be cut more smoothly with less labor compared to conventional manual reeds. However, since the scissors blade is moved in the front-rear direction, the resistance is large and the capacity of the drive device cannot be reduced so much.

  The present invention provides a manual scissor with a drive device that can cut a workpiece more smoothly with less labor and can reduce the capacity of the drive device in a manual scissor equipped with a drive device. It is in.

  According to a first aspect of the present invention, there is provided a driving device in which a blade is mounted on an intermediate portion in the front-rear direction of the rack so as to be horizontally movable in the horizontal direction of the rack, and the blade is reciprocated in the horizontal direction with a predetermined stroke. An electric rotary motor, an electric linear motor, an electromagnetic force drive device, an ultrasonic motor, etc.) are provided on the stand.

  When the blade is vibrated with a predetermined stroke in the left / right direction with the drive device, the sharpness of the blade is increased, and when the blade is pulled back (when pulling), or pushed (when pressed) The resistance to this force is greatly reduced, and the work is greatly facilitated by smooth cutting in the front-rear direction. Since the scissors blade slides in the lateral direction perpendicular to the cutting direction, the driving force of the driving device is small, and the driving device can be greatly reduced in capacity.

  The invention according to claim 2 of the present invention is the manual scissors with drive device according to claim 1, characterized in that left and right cutting edges are formed by notches at both ends of the cutting edge of the scissors blade. This is a manual scissor with a driving device.

  By providing left and right cutting edges at both ends of the cutting edge at the lower end of the scissors blade, cutting can also be performed in the left and right directions, the horizontal sliding cutting becomes smoother, and the cutting in the front and rear direction becomes even smoother.

  Since the present invention is configured as described above, the following effects can be obtained.

(1) By oscillating the blade with a predetermined stroke in the left-right direction with the drive device, the sharpness of the blade is increased, the resistance to the force when brushing is greatly reduced, and the work is performed by smooth cutting in the front-rear direction Is extremely easy. In addition to saving labor, anyone can make a good hit.

(2) Since the scissors blade slides in the lateral direction perpendicular to the cutting direction, the driving force of the driving device is small, the driving device can be greatly reduced in capacity, and the cost can be reduced.

(3) By providing left and right cutting edges at both ends of the cutting edge at the lower end of the scissors blade, the horizontal sliding cutting becomes smoother, and the cutting in the front-rear direction becomes even smoother.

  Hereinafter, the present invention will be described based on the illustrated embodiment. FIG. 1 is a side view, a plan view, and a top view of a scissors blade showing an embodiment of the scissors of the present invention.

  As shown in FIG. 1, a V-shaped chip discharge hole 2 is formed in the front-rear direction intermediate portion of the gantry 1 in a side view. A blade 3 is attached.

  In the present invention, the scissors blade 3 is mounted so as to be horizontally movable in the left-right direction perpendicular to the front-rear direction (stripping direction) of the scissor base 1, and this scissors blade 3 is reciprocated in the left-right direction with a predetermined stroke by the drive device 5. Let

  A guide groove 10 that is continuous in the left-right direction is formed on the mounting surface of the scissors blade 3, and a guide member 11 that is inserted into the guide groove 10 is integrally provided on the back surface of the scissors blade 3. Is supported so that it can slide stably in the left-right direction. In order to be able to adjust the saw blade 3 in and out, the guide groove 10 is formed in the substrate 12, and the substrate 12 is moved along the inclined surface so that the saw blade 3 and the substrate 12 are adjusted in and out. To do.

  The drive device 5 is housed in the base 2 and uses, for example, an electric rotary motor 20 and converts the rotation of the motor 20 into a linear reciprocating motion in the left-right direction (for example, a crank using a crank and a crank rod). The mechanism) is connected to the scissors blade 3, and the scissors blade 3 is vibrated with a predetermined stroke in the left-right direction. The drive device 5 may be an electric linear motor, an electromagnetic force drive device (solenoid), an ultrasonic motor, or the like.

  Left and right cutting blades 3b are formed at both ends of the cutting blade 3a of the scissors blade 3 so that cutting can be performed during sliding movement in the left and right direction.

  The scissors blade 3 can be provided with a backing metal (presser plate), and the scissors blade 3 can be used by stacking a plurality of two or more.

  FIG. 2 is an example in which a plate blade 15 having a cutting edge 15 a for preventing clogging of chips is provided on the surface of the scissors blade 3. The plate blade 15 has a cutting edge 15 a at the tip, and is screwed to the gantry 1 with a bolt 17 penetrating the heel blade 3.

  Also in this case, the guide groove 10 is formed on the upper surface of the scissors blade 3, the guide member 11 is formed on the lower surface of the plate blade 15, and the bolt hole of the bolt 17 is formed as a slide hole 16 that is long in the left-right direction. The saw blade 3 is allowed to slide stably in the left-right direction. A spring 18 is disposed under the bolt neck of the bolt 17 to press the plate blade 15 against the scissors blade 3.

  In the manual scissors with a drive device having the above-described configuration, the scissors blade 3 is pulled by pushing or pushing in the front-rear direction while reciprocating the scissors blade 3 with a predetermined stroke in the left-right direction. Since the scissors blade 3 vibrates with a predetermined stroke in the left-right direction, the sharpness of the scissors blade 3 is increased, the resistance to the force at the time of scoring is greatly reduced, and smooth cutting in the front-rear direction makes the work extremely easy. Further, since the scissors blade slides in the horizontal direction, the driving force of the driving device 5 can be small, and the capacity of the motor or the like can be greatly reduced. Further, by providing the left and right cutting edges 3b at both ends of the lower cutting edge 3a of the scissors blade 3, the horizontal sliding cutting becomes smooth, and the longitudinal cutting becomes even smoother.
