Example Embodiment

[0045] Example one

[0046] Reference figure 1 , Is a commutator segment 1 for commutator 2 disclosed in the present invention, which includes a segment body 17 and a hook 14. The sheet body 17 includes a contact block 11 and a clamping block 12. The contact block 11 is a rectangular parallelepiped and is provided with a connecting block 15 along its length. The end of the connecting block 15 away from the contact block 11 is provided with a connecting sheet 13 in the vertical direction, and the connecting sheet 13 The end away from the connecting block 15 is fixedly connected to the clamping block 12. The length of the connecting piece 13 is less than the length of the contact block 11 and the clamping block 12. The contact block 11, the connecting block 15, the connecting piece 13 and the clamping block 12 are integrally formed, and the sheet body 17 The overall shape is an I-shape, which is convenient for the commutator piece 1 to be assembled into the commutator 2. The hook ...

[0050] Example two

[0051] Reference figure 2 with Figure 4 , Is a kind of production equipment applied to the commutator 1 in embodiment 1 disclosed by the present invention, including a body 61, a stamping cover 5 and a stamping die 4. The body 61 is provided with a punch 62 that moves in the vertical direction, The bottom of the punch 62 is connected with the stamping cover plate 5. The stamping die 4 is located directly under the stamping cover plate 5 to fit into the stamping cover plate 5. The outer side wall of the stamping die 4 is provided with a feeding hole 47, and the feeding hole 47 conveys The elongated profile 3, in this embodiment, the elongated profile 3 is formed by drawing a elongated silver-copper alloy. The punch 62 applies pressure to the stamping cover plate 5, and then presses the elongated profile 3 in the lower stamping die 4.

[0052] Reference Figure 5 , The top end of the punching die 4 is sequentially provided with a first punching groove 48, a se...

Example Embodiment

[0060] Example three,

[0061] Reference Picture 10 The difference from the first embodiment is that the cross section of the two deformation grooves 141 on the commutator piece 1 is an isosceles trapezoid, the two deformation grooves 141 both penetrate the upper and lower end surfaces of the hook portion 14, and the linear distance between the bottom of the two deformation grooves 141 It is also 1.03mm, and the setting of the deformation groove 141 with an isosceles trapezoid cross-section can also reduce the pressure on both sides of the hook 14 when it is bent. The distance between the commutator segments 1 further increases the space where the enameled wire is wound around the commutator segment 1 and reduces the mutual interference between the enameled wires. When processing the commutator piece 1 in this embodiment, it is only necessary to change the shape of the fifth punch head 53 on the punch cover plate 5 to a shape that matches the deformation groove 141.

Abstract

The invention discloses a commutator segment for a commutator and production equipment of the commutator segment and belongs to the technical field of commutators. The invention aims to solve the problem that bulges and burrs are generated due to the fact that two sides of the hook part of a commutator segment are extruded outwards under pressure in a hooking process. The commutator segment is characterized in that the commutator segment comprises a segment body and a hook par; the segment body comprises a contact block and a clamping block; the contact block is provided with a connecting block in the length direction of the contact block; the connecting block is provided with a connecting sheet in the vertical direction of the connecting block; one end, far away from the contact block, ofthe connecting sheet, is fixedly connected with the clamping block in the length direction of the connecting sheet; the contact block, the connecting block, the connecting sheet and the clamping block are fixedly connected with one another; two ends of the connecting block, two ends of the connecting sheet and two ends of the clamping block jointly clamping grooves; one end of the contact block in the length direction of the contact block is fixedly connected with the hook part; deformation grooves are formed in two ends of the hook part in the width direction of the hook part; and the two deformation grooves penetrate through the upper end surface and the lower end surface of the hook part. With the commutator segment for the commutator and the production equipment of the commutator segment of the invention adopted, the problem that bulges and burrs are generated due to the fact that two sides of the hook part of a commutator segment are extruded outwards under pressure in a hookingprocess can be solved.

Description

technical field [0001] The invention relates to the technical field of commutators, in particular to a commutator segment for a commutator and production equipment thereof. Background technique [0002] The commutator is a component used for current commutation on DC motors and AC series motors in order to allow the motor to continue to rotate, commonly known as a commutator. Structurally, the commutator is a circle surrounded by several commutator segments, which are respectively connected to each tap on the rotor, and two electrodes connected to the outside are called brushes to contact it, and only two of them are in contact at the same time. The principle is that when the coil passes through the current, it will rotate through the attraction and repulsion force under the action of the permanent magnet. The brushes are separated, and the brushes are connected to the contacts corresponding to the set of coils that produce the driving force. Commutator segments are genera...
