[0002] Motor core slotting is an important part of the motor manufacturing process. It involves the slot processing of the stator and rotor of the motor core. Its main purpose is to punch out slots that meet the design requirements on the silicon steel sheet of the core so that the coil can be embedded in the subsequent motor assembly process to form an electromagnetic circuit. The accuracy and precision of the slot shape have a vital impact on the performance of the motor.

[0003] When the existing notching device for the motor core is working, it first notches the moving silicon steel strip and then reels the notched silicon steel strip. During the notching process of the silicon steel strip, the silicon steel strip is not straightened and tightened, which may easily cause the notch size of the notched silicon steel strip to be substandard, affecting the product quality of the motor core. At the same time, during the notching process, metal debris will be generated at the notch of the silicon steel strip, and the metal debris attached to the notch of the silicon steel strip may easily affect the normal reeling of the silicon steel strip.

At the same time, the extended end of the hydraulic cylinder drives the flip plate to rotate, and cooperates with the first lever to drive the sliding sleeve to squeeze the thrust spring downward, so that the baffle and the lifting square rod move downward. At this time, the extrusion force of the rotating roller on the silicon steel strip increases, and then cooperates with the transmission roller to rotate, so that the transmission roller cooperates with the rotating roller to provide a straightening and tightening pulling force to the silicon steel strip, ensuring that the size of the silicon steel strip notch meets the standard and avoids affecting the product quality of the motor core.

[0011] A further technical improvement of the present invention is that the vibration unit includes a first support frame and a second support frame fixedly connected to the processing table, the top of the first support frame is rotatably connected to a rotating rod, one end of the rotating rod is rotatably provided with a transmission wheel, and six rubber sheets are fixedly connected at equal angles on the outer edge surface of the end of the rotating shaft away from the driving motor, one of the rubber sheets is in contact with the other end of the rotating rod.

The protruding end of the hydraulic cylinder is also movably connected to one end of the flip plate through a second lever.

[0016] A working method of a high-speed slotting device for machining a motor core, the working method specifically comprising the following steps:

[0017] Step 1: Pull out the silicon steel strip on the winding wheel, and then place one end of it between the rotating roller and the conveying roller. At this time, the extended end of the hydraulic cylinder is in the shortest state, and the driving motor is turned on to make the conveying roller cooperate with the rotating roller to convey the silicon steel strip. The extended end of the hydraulic cylinder is controlled to extend to the longest, and the silicon steel strip is notched by the notching tooling in conjunction with the die groove and two modules, so that the waste material from the notching falls into the guide trough along the die groove and the discharge port, and then the waste material is recycled through the guide trough;

[0018] Step 2: When the extended end of the hydraulic cylinder is extended to the longest, the rubber plate first contacts the top surface of the silicon steel strip, and the push force of the push-pull spring on the rubber plate is cooperated, so that before the notching tool contacts the silicon steel strip, the rubber plate cooperates with the base to press and fix the silicon steel strip. At the same time, the extended end of the hydraulic cylinder drives the flip plate to rotate, and the first lever drives the sliding sleeve to squeeze the thrust spring downward, so that the baffle and the lifting square rod move downward. At this time, the extrusion force of the rotating roller on the silicon steel strip increases, and then the transmission roller rotates, so that the transmission roller cooperates with the rotating roller to provide a straightening and tightening tension to the silicon steel strip, ensuring that the size of the notch of the silicon steel strip meets the standard, avoiding affecting the product quality of the motor core;

[0019] Step 3: After completing the grooving of the silicon steel strip, control the extended end of the hydraulic cylinder to retract and reset, and drive the silicon steel strip to move through the conveying roller and the rotating roller, and perform the above operation again, so as to continue to grooving the silicon steel strip. The continuous rotation of the conveying roller and the rotating shaft causes the six rubber sheets to continuously impact the other end of the rotating rod. The rotating rod cooperates with the tension spring to drive the L-shaped flip rod to flip back and forth, so that the first impact bar and the second impact bar continuously impact the silicon steel strip, so as to shake off the metal debris attached to the notch of the silicon steel strip and prevent it from affecting the normal winding of the silicon steel strip; at the same time, turn on the vacuum tooling to absorb the metal debris that falls on the processing table.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When the present invention is in use, during the process of the extended end of the hydraulic cylinder extending to its longest length, the rubber plate first contacts the top surface of the silicon steel strip, and cooperates with the push-pull spring to exert a thrust on the rubber plate, so that before the notching tool contacts the silicon steel strip, the rubber plate cooperates with the base to press and fix the silicon steel strip. At the same time, the extended end of the hydraulic cylinder drives the flip plate to rotate, and cooperates with the first lever to drive the sliding sleeve to squeeze the thrust spring downward, so that the baffle plate and the lifting square rod move downward. At this time, the squeezing force of the rotating roller on the silicon steel strip increases, and then cooperates with the rotation of the conveying roller, so that the conveying roller cooperates with the rotating roller to provide a straightening and tightening pulling force to the silicon steel strip, thereby ensuring that the size of the notch of the silicon steel strip meets the standard and avoiding affecting the product quality of the motor core.

[0022] 2. When the present invention is in use, after completing the grooving of the silicon steel strip, the extended end of the hydraulic cylinder is controlled to retract and reset, and the silicon steel strip is driven to move by the conveying roller in cooperation with the rotating roller, and the above-mentioned operation is performed again, so as to continue to grooving the silicon steel strip. The continuous rotation of the conveying roller and the rotating shaft causes the six rubber sheets to continuously impact the other end of the rotating rod, and the L-shaped flip rod is driven to flip back and forth by the rotating rod in cooperation with the tension spring, so that the first impact bar and the second impact bar continuously impact the silicon steel strip, so as to facilitate the shaking off of metal debris attached to the notch of the silicon steel strip and prevent it from affecting the normal winding of the silicon steel strip.

Step 3: After the silicon steel strip is notched, the extended end of the hydraulic cylinder (1) is controlled to retract and reset, and the silicon steel strip is driven to move by the conveying roller (213) in cooperation with the rotating roller, and the above operation is performed again, so as to continue to notch the silicon steel strip. The conveying roller (213) and the rotating shaft (212) continue to rotate, so that the six rubber sheets (211) continuously impact the other end of the rotating rod (2056), and the L-shaped flip rod (2052) is driven to flip back and forth by the rotating rod (2056) in cooperation with the tension spring (2054), so that the first impact bar (2051) and the second impact bar (2057) continuously impact the silicon steel strip, so as to facilitate the shaking off of metal debris attached to the notch of the silicon steel strip.
