Description
Technical field
The invention belongs to technical field of motor manufacture, in particular to a kind of electrical-coil manufacturing method.
Background technique
Currently, when producing electrical-coil, it is necessary to punching is carried out to coil, is allowed to meet the height of design and thickness,
During punching, first is that processing large labor intensity, production efficiency is low and high production cost, when coil punching, needs special set
Standby and expensive blade, a piece of blade need 450-600 first, blade can only punching 5-6 platform coil, increase and be produced into
This, the coil section after punching needs to carry out molding Shape correction, and production efficiency is very low；Second is that needing manually to be formed whole
Shape processing, the size inaccuracy of coil, appearance is also poor, third is that in the grinding process, can generate a large amount of dust and
Material is scrapped, is polluted to environment.
Summary of the invention
When in order to overcome existing electrical-coil molding Shape correction, the shortcomings that polishing is processed is carried out, the present invention provides
A kind of manufacturing method of electrical-coil.
To achieve the above object, the present invention adopts the following technical scheme: a kind of electrical-coil manufacturing method, including following step
It is rapid:
(1) packaged winding former is assembled on coil winding machine and carries out coiling, after coiling, coil is packaged,
First stop collar is cleaned with acetone, the dirt on stop collar is removed, one layer of release agent is then coated on stop collar, then
Stop collar is fixed on mold core by the height support plate and positioning screw of design requirement；
(2) external mold is packaged, after encapsulation, line mould feeding drying chamber is carried out baking and is warming up to 110-118 degree, is protected
Stop heating after holding constant temperature 7-8 hours, the line mould baked is sent into pouring can, line mould is sent into temperature in pouring can and is not less than
70 degree, casting sebific duct is placed, is then preheated, be warming up to 64-74 degree, while starting the vacuum pump of pouring can, is taken out
Vacuum outgas makes vacuum degree reach 1mbar hereinafter, line mould temperature is maintained at 64-74 degree；
(3) during online mould moves into pouring can degassing, specified slack tank is added in resin, curing agent mould material and is distinguished
It heated, vacuumized, stirred, be allowed to uniformly mixed, before starting casting, adjust in pouring can that vacuum degree is to 4-6mbar, in tank
Temperature is maintained at 64-74 degree, and the temperature of pouring nozzle in pouring can is adjusted to 60-70 degree, and when starting casting, poring rate is according to line
The size of mould is adjusted, and makes its 40 seconds/stroke of speed, and the duration of pouring of each line mould controlled at 30-60 minutes, casting tree
The height of rouge is subject to pressurize after resin height be no more than stop collar；
(4) it being stood after being poured, time of repose is greater than 30 minutes, while keeping vacuum degree in tank is 4-6mbar,
Temperature is 64-74 degree；
(5) after standing, the charging valve of pouring can is opened, is allowed to be depressed into 1 atmospheric pressure, after pressing,
Repressurization to 3 atmospheric pressure, and pressing time at least at 30 minutes or more, keep resin fully penetrated in coil；Pressurization finishes
Afterwards, pouring can institute inflatable body is discharged, then is allowed to be depressed into 1 atmospheric pressure；
(6) the line mould being poured is sent into drying chamber, is warming up to 85 degree, and kept for temperature constant state at least seven hour, makes
Then resin gel is warming up to 110-120 degree again, kept for 8 hours stop heating, solidify resin, to natural cooling
Line mould is come out of the stove when spending to 60-70；
(7) the line mould after coming out of the stove demoulds, and is then gone out burr after molding, wedge angle with file, obtains motor
Coil.
The beneficial effects of the present invention are: after the present invention, processing coil is no longer needed using special punching equipment
With expensive blade, coil does not need reserved punching surplus when being poured, and the shaping after coil moulding by casting, processing time
Original one third is needed, labor intensity is alleviated, improves production efficiency；In addition, one-time formed coil dimension is accurate, outside
Appearance quality is good, exempts from punching coil using what the present invention was poured, either coil height or oil wall thickness is all very accurate.
Specific embodiment
The invention will be further described With reference to embodiment.
A kind of electrical-coil manufacturing method, comprising the following steps:
Packaged winding former is assembled on coil winding machine and carries out coiling, after coiling, coil is packaged, is first used
Acetone cleans stop collar, removes the dirt on stop collar, one layer of release agent is then coated on stop collar, then by setting
It counts desired height support plate and positioning screw is fixed on stop collar on mold core；Then external mold is packaged, has been encapsulated
Line mould feeding drying chamber is carried out baking and is warming up to 110-118 degree, stopped heating after being kept for constant temperature 7-8 hours, will bake by Bi Hou
Good line mould is sent into pouring can, and line mould is sent into temperature in pouring can and is not less than 70 degree, places casting sebific duct, then carries out pre-
Heat is warming up to 64-74 degree, while starting the vacuum pump of pouring can, carries out vacuumizing degassing, so that vacuum degree is reached 1mbar hereinafter,
