Embodiment Construction

[0028] Such as figure 1 As shown, the motor coil hydraulic shaping device according to the present invention includes an upper pressing plate 1, a lower pressing plate 4, two side molds 2, and a mold core 3.

[0029] The structures of the upper pressing plate 1 and the lower pressing plate 4 may be the same or different. But the opposite surface of upper pressing plate 1, lower pressing plate 4 is all provided with groove, and groove length direction and profile are identical, as figure 2 shown. Preferably, the upper pressing plate 1 and the lower pressing plate 4 can be designed to be the same according to the working platform of the hydraulic press, so as to facilitate borrowing and making.

[0030] The two side molds 2 are used to be placed on both sides of the groove of the lower platen 4, and the shape matches the shape on both sides of the groove; the mold core 3 is used to be placed in the middle of the two side molds 2, and the mold core 3 and the two side molds 2....

Abstract

The invention provides an oil pressure shaping device for a motor coil, and a method for shaping a motor coil. The oil pressure shaping device comprises an upper pressing plate, a lower pressing plate, two side molds and a mold core; wherein opposite surfaces of the upper and lower pressing plates are provided with grooves which have the same length direction and outline, the two side molds are used for being put at two sides of the groove of the lower pressing plate, and the shapes of the two side molds are matched with the shapes of the two sides of the groove; the mold core is used for being put between the two side molds, and the mold core can fully fill the groove of the lower pressing plate after being completely matched with the two side molds; and the height of a part which is exposed from the groove is higher than the height of the motor coil before shaping. The oil pressure shaping device of the invention has the beneficial effects that a conventional oil pressure shaping device for a coil is simplified, and in comparison with the conventional heavy shaping device, the oil pressure shaping device of the invention is low in steel consumption and concise in design, thus cost is saved, and the device does not deform under the pressure of a specified tonnage.

Description

technical field [0001] The invention relates to the technical field of motor coils, in particular to a motor coil hydraulic shaping device and a motor coil shaping method. Background technique [0002] As the core and important components of the motor, the main pole coil and additional pole coil of the rail transit DC traction motor, as well as the magnetic pole coil of the main generator, must be subjected to operations such as appearance shaping, inter-turn insulation, and ground insulation treatment after winding to meet the design requirements. and usage requirements. Due to the large size and weight of the coils of this type of motor, the magnetic pole coils of the main and auxiliary generators and the auxiliary pole coils of the DC motor are all shaped by oil pressure when the coils are shaped, and the applied pressure ranges from tens of tons to hundreds of tons. The design of the hydraulic shaping mold, the safety and convenience of the mold turning during operation...
