Abstract
The utility model discloses a composite coil mould. The composite coil mould comprises nose clamping mechanisms, nose pin moving mechanisms, arch supporting plates, round corner plates and round corner pressing plates, wherein each nose clamping mechanism is divided into a first clamp and a second clamp which are connected with the arch supporting plate through the nose pin moving mechanism; the arch supporting plate is connected with one end of the round corner pressing plate; the round corner pressing plate is connected with the round corner plate; and the arch supporting plate is made of a non-metal material. The composite coil mould has the advantages that: strength and rigidity are guaranteed, insulation of a coil is not damaged and coil quality and yield are improved, the conception is ingenious, and the design is rational.
Description
Technical field
The utility model relates to a kind of coil composite die.
Background technology
Because the alternating current machine service conditions is relatively harsh and abominable, therefore, to the manufacturing of AC stator coil and insulating requirements than higher.The motor coil bulging is one important procedure of motor manufacture process, is to adopt bulging equipment that the motor coil semi-finished product of coiling moulding are carried out bulging processing to reach the shape that is complementary with motor stator, rotor.
The stator coil expanding machine of each motor manufacturer production is finished product coil covering not damaged and the coil both sides symmetry after the assurance moulding at present, adopts the two expanding arms in same axle center mostly, is fixed with fixture block or hydraulic connecting rod and comes promptly coil on expanding arm.Stator coil rises also needs to use shaping mould to carry out shaping behind the type, damages easily again insulating barrier, the useful life of having reduced motor in the shaping process.In AC stator coil manufacture process, mould designed and that use all adopts metal material in the existing manufacturing process.Because coiling mould, expanding die directly contact with coil, in the coil manufacturing, easily coil insulation is damaged and breakage, influence the workmanship and the rate of finished products of coil.Through the high-frequency detection instrument coil insulation is carried out all position detections, adopt the coil qualification rate of metal die manufacturing to be about 16%.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of coil composite die.This composite die is skillfully constructed, reasonable in design, both guaranteed the strength and stiffness of mould, accomplished again not damage coil insulation, improved mass of coil and rate of finished products.
For achieving the above object, the utility model solves the technical scheme that its technical problem adopts and is:
A kind of coil composite die, comprise nose clamping mechanism, nose pin movable device, top arc plate, radius plate and fillet pressing plate, described nose clamping mechanism is divided into first clamp and second clamp, first clamp is connected with top arc plate by nose pin movable device with second clamp, described top arc plate is connected with an end of fillet pressing plate, the fillet pressing plate is connected with radius plate, and described top arc plate is made by nonmetallic materials.
As optimal way, described nonmetallic materials are selected from a kind of in nylon, polytetrafluoroethylene or the teflon.
The utility model adopts nonmetallic materials such as nylon, polytetrafluoroethylene and teflon mutually compound with metal die, forms composite die.Composite die had both guaranteed the strength and stiffness of mould, made die surface have incomparable flexibility of metal material and smoothness again, had accomplished not damage coil insulation, had improved mass of coil and rate of finished products.Through the high-frequency detection instrument coil insulation is carried out all position detections, adopt the coil qualification rate of composite die manufacturing to be about 93%.Qualification rate has improved more than 5 times with respect to prior art.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
The utility model is skillfully constructed, reasonable in design, both guaranteed the strength and stiffness of mould, accomplished again not damage coil insulation, improved mass of coil and rate of finished products.
