摘要： An electric power tool “A” operates a working part 5 by repeating rotation of a motor 4 in a normal direction and in a reverse direction one or more times. The motor 4 includes a brushless motor. Sensors H for detecting a position of a rotor 15 are provided on the motor 4 so as to be advanced by an electrical angle of 30°±θ° from an intermediate position between respective stator teeth 16 in a direction of the normal rotation of the rotor 15. A control part 20 for controlling the rotation of the motor 4 controls a driving signal of the motor 4 based on the results of detection by the sensors H. Moreover, the control part 20 selects a detection signal of the sensors H so that relation between the rotor 15 and the detection signal of the sensors H is equivalent in either of the normal rotation and the reverse rotation of the rotor 15.

摘要： A rechargeable electric tool includes a warning device which monitors a voltage of a power source battery and indicates a warning by means of an LED or a buzzer when the power source voltage is reduced to be equal to or lower than a reference voltage. The tool is configured such that, even when the warning is indicated, a control to interrupt a power supply to a motor is not performed, thereby enabling a usual operation in response to an activating operation on a trigger switch.

摘要： A reverse rotational number of a binding wire feed mechanism is set such that a binding wire is completely pulled back regardless of a boldness or flexibility of the binding wire, a diameter of a reinforcing bar or the like. A driven gear 14 having a V groove of the binding wire feed mechanism is brought into elastic contact with a main drive gear 13 having a V groove by a spring and the binding wire is fed by pinching the binding wire by the main drive gear 13 having the V groove and the driven gear 14 having the V groove. After feeding out the binding wire to form a loop around the reinforcing bar and clamping a front end of the binding wire by a twist mechanism, the binding wire feed mechanism is rotated reversely and the binding wire is pulled back to be wound around the reinforcing bar. After stopping the binding wire, the main drive gear 13 having the V groove and the driven gear 14 having the V groove are slipped relative to the binding wire to rotate idly and continue to rotate reversely until a predetermined rotational number.

摘要： A reinforcing bar binding machine is provided with a control unit operated in such a manner that at the time of turning on an electric power source switch, a setting position of a motor drive adjustment dial and a state of a trigger lever are read, and when the motor drive adjustment dial is at a specific setting position and when the trigger lever is turned on, a binding wire cutting mechanism is driven by a predetermined number of times for warming up the binding wire cutting mechanism. When the warming-up operation is carried out in a cold environment, it is possible to reduce the viscosity of grease coated on a mechanism portion. Therefore, it is possible to lower a viscosity of grease applied on a mechanical portion and conduct a reinforcing bar binding work without wasting a binding wire in the same manner as that in a warm environment.

摘要： A final gear (23) and a ball screw shaft (24) of a rotation drive system of a binding line twist mechanism are connected by a spline and a shaft portion of a center clamp plate (26) of a binding line clamp apparatus (25) is connected to a front end of the ball screw shaft (24). A shift mechanism for moving the ball screw shaft (24) and the binding line clamp apparatus (25) in a front and rear direction by a slide motor (22) is provided. A wire (W) is wound around a reinforcing bar (S) by a binding line feed mechanism, the wire is grasped by a front end portion of the binding line clamp apparatus (25) and thereafter, a shift mechanism applies a tension to a loop of the wire by moving rearward the binding line clamp apparatus (25). The binding line clamp apparatus (25) is rotated by a twist motor (21) and the shift mechanism twists up the wire by moving forward the binding line clamp apparatus (25). Since the wire is applied with the tension and twisted, a reinforcing bar binding strength of the wire loop is stabilized.

摘要： A front end of a ball screw shaft driven by a motor is connected with a binding line clamp apparatus (513) including three clamp plates (514, 515, 516). The left and right clamp plates (515, 516) are constituted to be brought into elastic contact with the center clamp plate (515) and close the left and right clamp plates by operation of cams (527, 528) when a sleeve is moved rearward. In a state of opening the clamp plates, a binding line is fed out to an upper side by passing through an interval between the right clamp plate (515) and the center clamp plate (514), formed in a loop shape and moved into an interval between the left clamp plate (516) and the center clamp plate (517). When the sleeve is moved rearward by driving to rotate a ball screw shaft, the left and right clamp plates are closed to grasp a front end and a rear end of the binding line loop and thereafter, the binding line clamp apparatus is rotated to twist the binding line to bind a reinforcing bar.
