Abstract
The utility model relates to a composite metal wire with a fan-shaped cross section. The composite metal wire is made of silver alloy and copper alloy, the upper surface of the composite metal wire is used as a working area and a supporting area is arranged below the working area. The composite metal wire has advantages of simple production method and low cost.
Description
Technical field
The utility model relates to a kind of wire, and relating in particular to a kind of cross section is fan-shaped clad metal wire.
Background technology
The commutator of electrical micro-machine is the electrical micro-machine core component, and the commutator inefficacy of electrical micro-machine can cause whole electrical micro-machine to break down.Usually making the electrical micro-machine commutator has dual mode, a kind ofly is: the multiple copper alloy stratiform composite material of preparation silver alloy, through striking out circular-arc element; And be made into commutator through injection mo(u)lding, and this mode is produced commutator, and advantage is that noble metal dosage is less; Production cost is lower; But shortcoming is a complex manufacturing technology, needs the punch forming of high accuracy progressive die during punching press, especially requires higher to its Sheet Metal Forming Technology of micro motor; Another kind is: the mode silver alloy noble metal is rolling through roller die or drawing is processed into special-shaped silk material; Can be made into commutator segment through simple die-cut bending blanking, be made into commutator through injection mo(u)lding again, adopt this mode to produce commutator; Advantage is: require lower to punch-forming mold; The also convenient commutator of making various micromachines, shortcoming is: whole commutator segment is a noble metal silver, and cost is higher; Especially silver-colored valency continues under the high situation, and is bigger to the manufacturing cost influence of downstream cost.
The utility model content
To the deficiency of prior art, it is fan-shaped clad metal wire that the utility model provides a kind of manufacture method simple cross-section, and this wire is used for the electrical micro-machine commutator, has the low advantage of cost.
The technical scheme of the utility model is following: the cross section that is used for the electrical micro-machine commutator is that fan-shaped clad metal wire is made up of silver alloy and copper alloy; The upper surface of said clad metal wire is the working region; Supporting zone is positioned at the below of working region, and the cross section of clad metal wire is fan-shaped.
Said working region is a silver alloy, and supporting zone is a copper alloy.
The beneficial effect of the utility model is:
(1) adopt silver alloy because described cross section is the working region of fan-shaped clad metal wire, supporting zone adopts copper alloy, and material cost is lower;
(2) because described cross section is the working region of fan-shaped clad metal wire is arc surface, with can injection moulding being assembled into commutator behind its shearing bending, technology is simple, and is not high to the required precision of equipment.
Description of drawings
Fig. 1 is a kind of structural representation in the utility model cross section.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Embodiment 1
Referring to Fig. 1, cross section is that fan-shaped clad metal wire is made up of silver alloy and copper alloy, and the upper surface of described clad metal wire is working region 1, and supporting zone 2 is positioned at the below of working region, and the cross section of clad metal wire is fan-shaped.The contact-making surface of described working region and supporting zone is an arc surface, and with can injection moulding being assembled into commutator behind its shearing bending, therefore, manufacture method is simple, and is not high to the required precision of equipment.Said working region is a silver alloy, and supporting zone is a copper alloy, can significantly reduce the consumption of noble metal, reduces cost, and can guarantee the performance of commutator.
Claims (2)
1. a cross section is fan-shaped clad metal wire, and this clad metal wire is made up of silver alloy and copper alloy, it is characterized in that: the upper surface of said clad metal wire is the working region, and supporting zone is positioned at the below of working region.
2. cross section according to claim 1 is fan-shaped clad metal wire, it is characterized in that: said working region is a silver alloy, and supporting zone is a copper alloy.
