Abstract

The invention is a long stator iron core component packaging process, belonging to electric machine manufacturing technical field, comprising the steps of: a. putting solidified long stator iron core component together with connecting piece into an epoxy resin or unsaturated polyester resin injection mould and heating to 60-200 deg.C, preserving heat for 2-60 min; b. pressurizing the injection mould while vacuumizing and pouring epoxy resin or unsaturated polyester resin and keeping 2-60 min at a pressure of 1-5MPa; c. opening the injection mould and putting injected piece into an oven or baking channel for post-solification and making the long station iron core packaged piece. And the invention has advantages of convenient operating, saving labor and time, simplifying injection device, etc. and the surface of the packaged long stator iron core component is compact, and smooth and birght and clean, and has no air holes and defects, and the invention is especially applied to packaging long stator iron core components for high speed magnetic suspension train and driving motor iron core components for city railway traffic.

Description

Technique for packaging long stator iron core assembly
Technical field
The present invention relates to a kind of technique for packaging long stator iron core assembly, belong to the motor manufacturing technology field.
Background technology
Long stator synchronous linear motor is by stator (armature; Rail portion) and mover (magnetic pole; Vehicle sections) form, its compact conformation, efficient and power factor are all very high, belong to a core technology in the high-speed maglev train, and technology requires very high.And the linear synchronous generator long stator is being undertaken suspension, propelling, vehicle power supply three big functions as the critical component of propulsion system and magnetic suspension system, plays crucial effects in high-speed maglev train.Vacuum pouring and vacuum automatic pressure gem technology are mainly adopted in the encapsulation of the long stator iron core assembly that existing high-speed maglev train is used, vacuum pouring process using mould vacuumizes the mode of direct casting epoxy resin in back and then curing, produce bubble or defective at assembly surface easily, influence the packing and the evenness of assembly surface; The vacuum automatic pressure gem arts demand is put into vacuum tank (chamber) with mould and vacuumized pressurization again, process equipment is had relatively high expectations, and operation easier is big, and is time-consuming.
Summary of the invention
The object of the present invention is to provide a kind of reasonable in designly, can satisfy the iron core lamination assembly instructions for use, the technique for packaging long stator iron core assembly that improves the quality.
The present invention is a technique for packaging long stator iron core assembly, it is characterized in that being undertaken by following processing step:
A, the long stator iron core assembly of solidified forming is packed in epoxy resin or the unsaturated polyester resin injection mould together with connector,, is heated to 60~200 ℃ by heater block, reach its injection temperature scope after, be incubated 2~60 minutes;
B, injection mould is pressurizeed while vacuumizing and casting epoxy resin or unsaturated polyester resin,, close vacuum pump then, under the pressure of 1~5Mpa, kept 2~60 minutes until injection mould relief hole flash;
C, open injection mould, remove cast gate, the overlap of injection member, injection member is put into baking oven or drying tunnel carries out back curing, the long stator iron core packaging part.
The described long stator iron core assembly is packed into together with connector also can preheat to 60~200 ℃ by heater block earlier behind epoxy resin or the unsaturated polyester resin injection mould.
Described heater block can be installed on the injection device or be directly installed on the injection mould.
Described heater block can be baking oven or drying tunnel, and injection mould directly puts into baking oven or drying tunnel heats;
Described rear curing time can be 5~8h, and temperature range is 120~220 ℃.
Pressuring method during described the cast can be air pressure or hydraulic pressure, the spiral extrusion way.
The present invention is optimized design by the packaging technology of long stator iron core assembly that existing high-speed maglev train is used, employing is packed the long stator iron core assembly of solidified forming into and is directly carried out the packaging technology of while vacuumizing pressurization and casting epoxy resin or unsaturated polyester resin in epoxy resin or the unsaturated polyester resin injection mould together with connector, many defectives of prior art have been overcome, have advantages such as handled easily, saving of work and time, simplification injection device, closely knit, smooth bright and clean, the pore-free of the long stator iron core assembly surface after the encapsulation, zero defect.Packaging technology of the present invention is applicable to the encapsulation of core assemblies such as micromachine, low-power machine, linear electric motors, motor special and transformer, is specially adapted to high-speed maglev train is used the drive motors core assembly with long stator iron core assembly and urban track traffic encapsulation process.
Embodiment
The present invention carries out according to the following steps:
1. the long stator iron core assembly of solidified forming is packed in epoxy resin or the unsaturated polyester resin injection mould together with connector, preheat to 60~150 ℃ by heater block.Heater block can be installed on the injection device, also can be directly installed on the injection mould, also injection mould directly can be put into baking oven or drying tunnel heats.
2. the epoxy resin or the unsaturated polyester resin injection mould of long stator iron core assembly of will packing into is heated to 120~200 ℃, reach its injection temperature scope after, be incubated 2~60 minutes.
3. open injection device and vacuum pump, the pressurization while vacuumizing simultaneously, vacuum degree is 0.07~0.1Mpa, the pressurization scope is 1~5Mpa; With air pressure or hydraulic pressure, spiral extrusion way casting epoxy resin or unsaturated polyester resin,, close vacuum pump then, under the pressure of 1~5Mpa, kept 2~60 minutes until mould relief hole flash.
4. unlatching injection molding removes cast gate, the overlap of injection member, and again with fixed head and connector combination, baking oven is put in lifting or drying tunnel carries out back curing, and rear curing time is 5~8h, and temperature range is 120~220 ℃.
5. after the temperature and time of curing regulation requires after reaching, open the long stator iron core assembly package that baking oven takes out shaping, check warehouse-in.
