Description

Technical Field

[0001] The present invention relates to the technical field of punching devices, in particular to a punching device for machining motor rotors. Background Art

[0002] The motor rotor is also the rotating component in the motor. A motor consists of two parts: the rotor and the stator. It is a device used to convert electrical energy into mechanical energy and vice versa. Motor rotors are categorized as motor rotors and generator rotors. Motor rotors can be classified as either internal rotor or external rotor. In the internal rotor, the central core of the motor acts as the rotating body, outputting torque (for motors) or receiving energy (for generators). In the external rotor, the outer body of the motor acts as the rotating body. These different methods facilitate various applications. Motor rotor laminations are thin, sheet-like parts manufactured through a stamping process and are typically made of magnetic materials such as electrical steel. These laminations are stacked one by one to form the motor's rotor core, which serves as a critical path for the motor's magnetic field.

In addition, by pulling the fixing pin 32, the tension spring 29 is stretched, so that one end of the fixing pin 32 is disengaged from the pin fixing hole 35 opened by the connecting block 34, thereby facilitating the removal of the connecting block 34 from the inside of the connecting groove 33, facilitating the replacement of the punching head 26, and improving the adaptability, thereby solving the problem that the punching head 26 model used in the punching device for the motor rotor in the prior art is fixed, and the punching head 26 needs to be replaced when the punching size is to be changed. However, the installation of the punching head 26 lacks a quick disassembly structure, which makes disassembly inconvenient and replacement troublesome.

[0031] In summary, the application enables the elastic deformation of the torsion spring 24 by rotating the blocking piece 21 to be parallel to the protruding block 20, so that the rotating disc 15 can be conveniently removed from the outer side of the rotating shaft 18, different sizes of the rotating disc 15 with the accommodating grooves 14 can be conveniently replaced, different diameter punches can be placed, and the practicability is enhanced.

[0032] A certain amount of punch to be punched is reserved in the inside of the blanking cylinder 8. When the accommodating groove 14 is aligned directly below the blanking cylinder 8 during use, the punch will automatically fall into the inside of the accommodating groove 14, and the driving motor 37 is started to drive the rotating shaft 18 connected with the output shaft to drive the rotating disc 15 to rotate, so that the punch is located directly below the lowermost punch head 26, at this time, the first hydraulic telescopic rod 10 is started to move the punch head 26 downward to punch the punch, the waste is dropped into the inside of the right drawer 16 through the second blanking port 38, when the punched punch rotates to the first blanking port 36, the punch will fall into the inside of the left drawer 16.

[0033] When the rotating disc 9 needs to be rotated, first adjust the second hydraulic telescopic rod 25 to be shortened, so that the clamping block 31 is separated from the limiting gear 27, then rotate the rotating disc 9 by a certain angle, and finally adjust the second hydraulic telescopic rod 25 to be lengthened again, so that the clamping block 31 is clamped with the limiting gear 27, so that the rotating disc 9 after rotation is fixed. When the stamping head 26 needs to be disassembled, first pull the plug-in pin 32, so that the tension spring 29 is stretched, so that one end of the plug-in pin 32 is separated from the inside of the pin hole 35, then take out the connecting block 34 from the inside of the connecting groove 33, and remove the stamping head 26. When the rotating disc 15 needs to be disassembled, first adjust the liftable vertical plate 5 to be raised, so that the lower end of the blanking cylinder 8 is away from the rotating disc 15, then turn the blocking piece 21 to be parallel to the protruding block 20, so that the torsion spring 24 is elastically deformed, and finally take the rotating disc 15 from the outside of the rotating shaft 18 upward.

[0034] The above-described embodiments only express certain embodiments of the present application, which are described in detail and specifically, but should not be understood as a limitation on the scope of the present application; it should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application; therefore, the protection scope of the present application should be subject to the appended claims.
