Die for winding machine and die closing device for die

Abstract

The invention relates to a die for a winding machine and a die closing device for the die. The die closing device comprises a device body and a shaping module, wherein the device body comprises a base plate and two main boards which are arranged at intervals on one surface of the base plate; the interval between the two main boards is gradually reduced from the base plate; a mounting hole is formed in the base plate; a main shaft of the winding machine can pass through the mounting hole to be between the two main boards; the side surfaces of one of the sides of the two main boards, far away from the base form a clinging surface which is used for protecting a rotor iron core; the shaping module comprises four end parts shaping blocks; two end part shaping blocks are arranged on each main board; two end part shaping blocks on different main boards are corresponding to a bending area; the four end part shaping blocks can be driven by the main shaft to move toward or far away from the rotor iron core in order to press a varnished wire from the bending area on to the rotor iron core. With the adoption of the die closing device, a rotor with the characteristic of high groove fullness can be manufactured.

Description

technical field [0001] The invention relates to the technical field of rotor winding, in particular to a mold for a winding machine and a mold clamping device thereof. Background technique [0002] The eps (Electric Power Steering, electric power steering system) rotor includes a rotor core and an enameled wire wound on the rotor core. Such as figure 1 As shown, when producing the rotor, when winding the enameled wire 12 on the rotor core 11, it is necessary to hang the enameled wire 12 on a certain hook 22 of the commutator 21, and control the rotor core 11 and the commutator 21 to rotate at the same time. angle, so that the enameled wire 12 is hung on the hook 22 stably. Then the enameled wire 12 is wound from one wire slot 13 of the rotor iron core 11 to another wire slot 13 of the rotor iron core 11, thereby obtaining a circle of enameled wire 12, and multiple turns of the enameled wire 12 form a coil of the rotor. After obtaining the first coil, control the rotor iro...

AI Technical Summary

Problems solved by technology

The number of coils that can be accommodated in each wire slot 13 directly affects the performance of the rotor, but when the winding machine is winding into the wire slot 13, it is difficult to move the enameled wire 12 to the slot bottom position of the wire slot 13, resulting in There is no enameled wire 12 at the bottom of the wire slot 13, and the enameled wire 12 is quickly accumulated in the bending area 15, so that as many coils as possible cannot be wound in the wire slot 13, and a rotor with a high slot filling rate cannot be obtained.
