Example Embodiment

[0026] Examples:

[0027] Such as figure 1 As shown, the commutator segment includes a first elongated portion 1, a second elongated portion 2 arranged side by side, and a connecting portion 3 arranged between the first elongated portion 1 and the second elongated portion 2.

[0028] Such as figure 2 The device shown for processing the commutator includes an upper mold base 4 and a lower mold base 5 adapted to the upper mold base 4. The upper mold base 4 and the lower mold base 5 move along the direction of the profile 6 A press forming unit 7 and a punching unit 8 are arranged in sequence. The end face of the profile 6 is an I-shape.

[0029] Such as image 3 As shown, the press forming unit 7 includes an upper pressing plate 9 arranged at the bottom of the upper mold base 4 and a lower pressing plate 10 arranged on the lower mold base 5 and located below the upper pressing plate 9, and between the upper pressing plate 9 and the lower pressing plate 10 is provided with The cavity...

Abstract

The invention relates to a device for processing a reversing sheet, comprising an upper mold base and a lower mold base adapted to the upper mold base, wherein a pressing molding unit and a punching unit are sequentially arranged between the upper mold base and the lower mold base along a profile moving direction. Compared with the prior art, the invention converts the single punching process of the existing commutating sheet into continuous punching process, so that each person can process 700 PCS copper strips per minute per device, thus greatly improving the processing efficiency of the commutating sheet and reducing the production cost of the commutating sheet. I-shaped profiles (non-flat profiles) close to commutator are selected for machining, and the pressing surfaces of upper and lower platens are changed to profile surfaces (non-planar), which reduces the difficulty and complexity of commutator machining and improves the efficiency and machining accuracy of commutator machining.

Description

technical field [0001] The invention belongs to the technical field of motor component processing, and relates to a device for commutator segment processing. Background technique [0002] In the motor industry, the commutator of the rotor of a high-power motor is an indispensable part. It has a large demand, many types, and high cost. The main part of the commutator, the commutator (copper bar) Very important. At present, the commutator segments of the commutator on the market are mostly processed by stamping profiles, and each machine can process 150-180 PCS copper bars per minute. They are all produced through intensive labor, with low benefits and high costs. . Therefore, how to improve the efficiency and machining accuracy of commutator segment processing is an urgent task in the field of commutator segment processing. Contents of the invention [0003] The object of the present invention is to provide a device for commutator segment processing in order to overcome ...
