Problems solved by technology

During lamination, the positioning of tension screw hole 2', slot 3' and keyway 5' are very demanding, the degree of freedom in determining the number of slots is extremely low, and the manufacturing process is cumbersome. When the slot shape changes, it is necessary to Re-open the compound die, the cost is greatly increased

Embodiment Construction

[0019] A large and medium-sized motor link segment of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] see figure 2 , which shows one of the present invention, a large and medium-sized motor link segment, which includes several fan-shaped punches 11 that surround a full-circle punch 1, and the outer diameter of the full-circle punch 1 is greater than or equal to 1000mm, there is a seam 12 between every two adjacent sector pieces 11, and the seam 12 is dovetail-shaped.

[0021] In this embodiment, the diameter of the motor punch is 1240mm, and the number of slots is 172. Six sector pieces 11 are used to form a full circular punch 1. Among the six sector pieces, there are four first sector pieces 111 and two The second fan-shaped piece 112 is formed, the first fan-shaped piece 111 has 29 slots, the second fan-shaped piece 112 has 28 slots, and two first fan-shaped pieces 111 are sandwiched between the two second fan-...

Abstract

The invention provides a chaining segmental strip for large and middle scale electric machine and manufacturing method thereof, the chaining segmental strip comprises a segmental punching strip of complete round-shaped punching strip enclosed by a plurality of strips, a seam is dovetail-shaped arranged between each two neighboring segmental strips. The method comprises calculating number of slot of each segmental strip, blanking, splicing, and punching. The invention can effectively control radial and tangential displacements between the segmental strips, and the shape and the number of the slot are not constrained, the manufacturing method is simple, thereby reducing the labor intensity.

Description

technical field [0001] The invention relates to a link segment, in particular to a link segment for large and medium-sized motors and a manufacturing method thereof. technical background [0002] Usually, punching with a diameter of less than 1000mm is punched in a full circle. However, when the outer diameter of the punching of a large and medium-sized motor is greater than 1000mm, which exceeds the manufacturing width of the existing silicon steel plate, it cannot be directly punched in a full circle. For punching sheets with large diameters that cannot be used as a full circle, fan-shaped punching is generally used, and fan-shaped sheets are stacked. [0003] see figure 1 , is a kind of fan-shaped piece in the prior art, including several pieces of fan-shaped piece, on which there are tightening screw holes 2', each piece of fan-shaped piece 4' needs to be punched with a double die, and its groove shape and number of grooves are fixed . The seam of sheet and sheet just...
