The method includes the following steps: (1) a conductor is processed and made into a certain dimensional accuracy; (2) a mica tape painted with an insulation material is wrapped on the conductor; the conductor covered by the electromagnetic wire is drawn with a rolling-drawing method to lead the dimension of the conductor to reach high accuracy; The insulation material adopts mica tape with reinforced polyester film to enhance the anti-voltage, anti-corona and anti-drawing strength, etc. capability indexes of the electromagnetic wire; the wrapping process is controlled by a digital driving service system, a start-stop program of weaving, a stroboscopic indicator and a manufacturing-control software, thus realizing the purpose of the invention.
Description
Technical field
The present invention relates to a kind of manufacture method of lapping electromagnetic wire, particularly a kind of multi layer cloud master tape lapping electromagnetic wire manufacture method that is used for high-voltage motor.
Background technology
At present; because motor manufacture level development both at home and abroad is swift and violent; particularly external high-output power, the try one's best small and exquisite electric machine structure and the environmental protectionization of production process have proposed harsh specification requirement for the electromagnetic wire of motor heart component: as the insulating barrier that requires electromagnetic wire to have high pressure resistant, anti-corona, surface will approach as much as possible, high-precision overall dimension, high-precision wrapped tolerance and do not have impregnated insulating paint manufacturing etc.
This electromagnetic wire has only domestic minority electromagnetic wire producer producing at present, also has only world-class electrical machinery plant using, the creating of our success, and offer the use of how tame foreign motor producer.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high-voltage motor with multi layer cloud master tape lapping electromagnetic wire manufacture method, specification requirements such as, anti-corona high pressure resistant for the motor electromagnetic line now to satisfy.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
A kind of high-voltage motor multi layer cloud master tape lapping electromagnetic wire manufacture method is characterized in that it comprises following step:
1) conductor is processed, made certain dimensional accuracy;
2) it is wrapped on conductor to be coated with the mica tape of insulating material.
Described conductor dbus cross roll-daraf(reciprocal of farad) processes, and earlier through the rolling certain size of finish rolling, draws through mould then, can keep the high accuracy of conductor size.
Described conductor is a copper conductor.
Described insulating material is a mica tape, has covered one deck mylar by adhesive glue on the described mica tape, can improve performance index such as the reactance voltage of electromagnetic wire, anti-corona, tensile strength.
The composition of described mica tape is a mica paper, accounts for mica tape content 〉=45%wt.
Described adhesive glue is the epoxies adhesive glue, accounts for 7～10%wt of mica tape content.
Described mylar is used the PET film for the electrician, and its thickness is 0.019～0.025mm.
Described wrapped Tension Control precision is 0.1%.
The wrapped interstice coverage of described mica tape is 0.1～0.3mm.
Layer in the described wrapped process and the lapping rate precision between the layer are ± 1.0mm.
High-voltage motor of the present invention multi layer cloud master tape lapping electromagnetic wire manufacture method, roll by the conductor in the middle of the electromagnetic wire is used-daraf(reciprocal of farad) draws, make the size of conductor reach high accuracy, the mica tape that insulating material adopts polyester film to strengthen, improve performance index such as the reactance voltage of electromagnetic wire, anti-corona, tensile strength, startup, shut down procedure, stroboscopic display instrument, production process Control Software by digital drive service system, establishment are controlled whole wrapped process, realize purpose of the present invention.
Embodiment
A kind of high-voltage motor multi layer cloud master tape lapping electromagnetic wire manufacture method, it comprises following step:
1) conductor is processed, made certain dimensional accuracy;
2) apply insulating material in surface of conductors;
3) mica tape and the conductor that will be coated with insulating material carries out wrapped.
Described conductor is a copper conductor.
In the present invention, described conductor dbus cross roll-daraf(reciprocal of farad) processes; Conductor is rolled down to certain size through finish rolling earlier, passes through the stretching of mould then, one-shot forming; Because conductor enters the rolling basic forming of the preceding process earlier of mould milling train, when entering mould and draw, just very little to the stretching resistance of mould, greatly reduce wearing and tearing for mould, solved the problem of the conductor size precision fluctuation that die wear brings; Simultaneously, the conductor size before entering mould can be regulated arbitrarily by regulating rolling mill roll, can guarantee the precision of conductor size after entering mould like this, keeps the fluctuation of conductor size to be controlled in the scope of 0.01mm, is implemented in the size high accuracy of conductor.
Among the present invention, selection for insulating material, in order to make electromagnetic wire reach anti-high voltage, anti-corona and high tensile strength, insulating material among the present invention adopts mica tape, on described mica tape, covered one deck mylar, can improve performance index such as the reactance voltage of electromagnetic wire, anti-corona, tensile strength by adhesive glue.
The composition of described mica tape is a mica paper, accounts for mica tape content 〉=45%wt, and described adhesive glue is the epoxies adhesive glue, accounts for 7～10%wt of mica tape content, and described mylar is used the PET film for the electrician, and its thickness is 0.019～0.025mm.
Because the thickness and the Unit Weight of mica tape are standard codes, and the mica composition in required standard range changing mica tape, adhesive glue composition and mylar composition can change indexs such as reactance voltage, anti-corona, tensile strength, can satisfy the specification requirement of different user.
Mica tape wrapped is the key during electromagnetic wire is made, for reaching thin dielectric layer and keeping electromagnetic wire in the motor coil manufacture process, not damage mica tape after the bending, mica tape is must the gap wrapped and for reaching high voltage withstanding, again can not impregnated insulating paint, thus wrapped gap, layer with layer between lapping all to accomplish as much as possible little.
Among the present invention, startup and wrapped rotary speed precision of shut down procedure control by high-precision digital drive dress system establishment reach 0.01%, by control mica tep reel in process of production the wrapped tension force precision of the change control mica tape of diameter in 0.1%, thereby make being controlled between 0.1～0.3mm of the wrapped gap strictness of mica tape; By the stroboscopic display instrument is installed in equipment, show in real time in the wrapped process layer with layer between the real-time condition of lapping power, make lapping rate precision be strict controlled in ± 1.0mm between; Simultaneously,, data and operation in all production processes are presented on the touch-screen, greatly help operation and production assurance by production process monitoring software.
More than show and described basic principle of the present invention and principal character and advantage thereof.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
