[0027] The first motor 212 described in this patent, a motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (i.e., the stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magnetoelectric dynamic rotating torque. Motors are divided into DC motors and AC motors according to the different power supplies used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the rotational speed of the stator magnetic field of the motor does not remain synchronous with the rotational speed of the rotor). A motor mainly consists of a stator and a rotor. The direction of the force on the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic induction line (magnetic field direction). The working principle of the motor is the action of the magnetic field on the current, which causes the motor to rotate.

[0028] The working process is as follows:

[0029] 1. The staff can first push the machine body 1 to the location where it is needed through the movable wheels 3, and then connect the power supply device to the machine body 1. When processing the bolt later, first insert the workpiece from the front to the back into the pressure plate 4, so that the workpiece fits against the inner side of the pressure plate 4. Then the staff can rotate the screw rod 9 by turning the second handle 10. Thus, the screw rod 9 will rotate in cooperation with the limit frame 8 through the thread. The screw rod 9 continuously pushes out to the left until the limiting member 11 slides to the left end of the chute 12 and fits against the workpiece. Then the staff can stop rotating, so as to achieve the effect of limiting the workpiece. Then, through the operation of the machine body 1, the processing effect of bending the workpiece is realized;

[0030] 2. After the workpiece is processed, the generated debris and impurities will fall on the workbench 1. At this time, the staff can start the first motor 212 to work, and the output shaft of the first motor 212 can drive the fan blade 213 to start rotating at a high speed. Because it is a closed environment, the high-pressure wind force can absorb the external metal debris and impurities, so that the metal debris and impurities can be sucked in through the suction port 25, and the impurities are introduced into the dust bag 22 through the connecting pipe 24. The wind will be filtered by the first filter 215 and the second filter 216, and then discharged from the air outlet 214, so that the impurities can be sucked into the dust bag 22 for storage;

[0031] 3. However, during long-term use, dust and other impurities are prone to adhere to the inner wall of the dust bag 22, which is inconvenient for the staff to clean, and long-term accumulation will greatly reduce the storage capacity of the dust bag 22. At this time, the second motor can start to work, and the output shaft of the second motor can drive the rotating shaft 2341 to make a circular motion. Because the turntable 2343 arranged on the upper end of the rotating shaft 2341 is an equilateral triangle turntable, during the rotation of the turntable 2343, it can rotate with the rotating wheel 2344, thereby realizing the swing rod 2345 to make a left and right reciprocating motion in the limit block 2346, so that the swing rod 2345 can repeatedly hit the dust bag 22 to knock off the dust on the inner wall of the dust bag 22, and when the dust bag 22 needs to be cleaned, the first handle 6 is pulled to open the movable door 5 so that the dust bag 22 can be taken out for cleaning.

[0032] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.
