Description

Technical Field

[0001] The invention relates to the technical field of rotor copper bar end processing, in particular to a rotor copper bar end forming machine. Background Art

[0002] At present, the kinetic energy of wind is converted into mechanical kinetic energy, and then the mechanical energy is converted into electrical kinetic energy. This is wind power generation. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed of rotation through the speed increaser to drive the generator to generate electricity. The rotor refers to the rotating body supported by the bearing, which is mostly the main rotating part in power machinery and working machinery. Objects such as optical disks that do not have their own rotating shaft can be regarded as a rotor when a rigid connection or additional shaft is used;

[0003] With the development of the wind power industry, semi-closed slot rotors have become an industry trend. However, the semi-closed slot rotor structure cannot embed the rotor copper bars formed at both ends. The current wire embedding process for this type of motor is to first form the N end of the copper bar, embed it into the rotor slot, and then manually form the D end of the copper bar. This method has low production efficiency.

[0004] The twisting and bending of the rotor copper bars depends entirely on the joint efforts of multiple personnel. Only one copper bar is formed at a time, while there are dozens to hundreds of copper bars that need to be formed on a rotor. This results in huge labor intensity, time-consuming and labor-intensive work, and extremely low work efficiency. Three people can only complete the copper bar forming operation of one rotor in a day. Summary of the invention

[0032] The copper bar end forming die 7 comprises an outer die 12, an inner die 13, a servo motor 14 and a working frame 16. The two servo motors 14 are respectively installed at the middle of the front ends of the two sides of the working frame 16 by bolts. The inner die 13 is movably installed in the middle of the inner cavity of the working frame 16. The outer die 12 is movably installed outside the inner die 13.

The teeth and grooves are meshed, and the servo motor 14 is electrically connected to the electric control mechanism 1. In this way, the ends of the inner and outer ring copper bars of the rotor end are clamped by the circumferential grooves of the outer mold 12 and the inner mold 13 of the copper bar end forming mold 6, and the outer mold 12 and the inner mold 13 are driven by the servo motors 14 on both sides, respectively, and rotate counterclockwise or clockwise in the opposite direction, respectively, clamping the copper bar end to drive the copper bar to twist a certain angle to form an integral body. When the forming work starts, the copper bar end forming mold 7 is pushed forward by the mold pushing mechanism 8, so that the forming is carried out with the movement, forming a specific forming motion curve;

[0033] The outer mold 12 and the inner mold 13 are provided with a plurality of slots at equal intervals. The working frame 16 is a circular ring structure when viewed from the side. A fixing frame plate is installed at the bottom of the working frame 16 by bolts, and the bottom of the fixing frame plate is slidably connected to the top of the guide rail, so that the root of the copper bar is located inside the slot during the forming operation.

[0035] Working principle: During processing, the present invention utilizes a crane or other equipment to hoist the rotor body 3 onto the rotor lifting and lowering mechanism 4, and the crane can be driven away. The rotor lifting and lowering mechanism 4 realizes the lifting function through an electric telescopic rod, which facilitates the positioning and clamping of the rotor body 3 on the rotor clamping mechanism 2. After the rotor is clamped and fixed by the rotor clamping mechanism 2, the rotation of the rotor body 3 during the copper bar forming operation is prevented. The copper bar clamping follower mechanism 6 is used to clamp the root of the copper bar, so that the root of the copper bar is engaged with the inner cavity of the latch mechanism 9 and fixed on the arc groove of the follower disk 10. When the forming work is performed, it rotates along the copper bar forming path, so that the copper bar forms an arc angle and passes through the guide disk 17 at the same time. Moreover, the guide disk 8 can also rotate together with the copper bar during the forming process, and the follower guide disk 17 A guide groove is provided on the back, and the tail of the latch mechanism 9 is clamped in the guide groove of the follower guide plate 17 and slides in the centrifugal direction. After the molding operation is completed, the guide plate 17 and the follower plate 10 can be driven by the single-phase motor 11 to move and perform the core pulling action, so that the copper bar can be demoulded, and the ends of the inner and outer ring copper bars of the rotor end are clamped by the circumferential clamping grooves of the outer mold 12 and the inner mold 13 of the copper bar end molding mold 6, and the outer mold 12 and the inner mold 13 are respectively driven by the servo motors 14 on both sides, respectively rotating counterclockwise or clockwise in the opposite direction, clamping the copper bar end to drive the copper bar to twist a certain angle and integrally mold. When the molding work starts, the copper bar end molding mold 7 is pushed forward by the mold pushing mechanism 8, so that the molding is carried out in a follow-up manner, forming a specific molding motion curve;

[0036] After the forming operation is completed, the copper bar clamping follower mechanism 6 first performs a core-pulling action to allow the clamping pin mechanism to break away from the contact with the copper bar, and then pushes the copper bar end forming mold 7 back, and then releases the rotor clamping mechanism 2 from clamping the rotor shaft, pushes the rotor clamping mechanism 2 away from the rotor, and then uses a crane or other equipment to lift the rotor as a whole through a sling, and the rotor end copper bar forming operation process is completed.
