DETAILED DESCRIPTION OF THE INVENTION

[0014] The present invention will be further described below with reference to accompanying drawings by embodiments.

[0015] As shown in FIGS. 1 and 2, the present invention provides a rotor coil shaping device, including a locating piece 1 and a press piece 2 located above the locating piece 1. A locating boss 11, extending upward and having a width the same as that of a rotor slot opening of a rotor, is provided in the middle of the locating piece 1 in a longitudinal direction, stop bosses 12 extending upward are provided at both front and rear ends of the locating piece 1, and upper shaping blades 21 each having an arc groove opening downward are fixed on a lower side of both front and rear ends of the press piece 2.

[0016] The locating piece 1 is detachably fixed on the locating base 3 by screws, and the locating base 3 is sleeved on two vertically arranged guide rods 4, and a lower end of each guide rod 4 is fixed to a base plate 5. A spring 6 sleeved on each guide rod 4 is provided between the locating base 3 and the base plate 5, lower shaping blades 51, each extending upward and having an arc groove opening upward, are provided on the base plate 5, and each lower shaping blade 51 located under each upper shaping blade 21 is provided on each of front and rear sides of locating base 3. A nut is screwed at an upper end of the guide rod 4 is to prevent the upward disengagement of the locating base.

[0017] A V-groove opening upward is formed on the locating base 3 and includes two supporting groove faces 31 aslant arranged to form a V-shaped structure, and the locating piece 1 is fixed in the middle of the V-groove so that the locating piece 1 is located between the two supporting groove faces 31.

[0018] The press piece 2 is fixed at an output end of a press 7, and one end of a guide piece 8 is fixed to the press piece 2 while the other end thereof is located in a vertically arranged guide slot 91 of a fixed plate 9. The press 7 which is a gas cylinder is fixed on the base plate 5 by a bracket 50.

[0019] The present invention has the advantages of improving the production efficiency and reducing the labor intensity of workers.
