Description
Technical field:
The manufacture method of the relevant a kind of linear synchronous motor long stator of the present invention, especially a kind of method for continuous production that is used for the linear synchronous motor long stator of magnetic suspended railway.
Background technology:
The long stator linear electric machine is main carrying and a driver part of high-speed maglev train rail system, for magnetic suspension train provides suspending power and actuating force.The manufacturing technology of electromagnetism structure assembly long stator can be referring to German patent DE 41 15 936 A1 of public publication on the 14th August in 1997 in the prior art neutral line synchronous machine.This patent has proposed a kind of manufacture method of electromagnetism structure assembly, and resulting product is the magnetic pole form on the magnetic suspended railway, or the long stator iron core form of long stator linear electrical generator.
The manufacture method that this patent provided is roughly: go out the original electrical sheet of given shape, hot pressing is cohered the back and is constituted laminated core; Upper notch place at this laminated core inserts connector, iron core is inserted in left and right two moulds again, closes up, and withstands connector from bottom to top by hydraulic means again; Then indurative intermixture (as epoxy resin) is poured in the mould, and intermixture hardened or age-hardening, so the laminated core envelope is wrapped, and make it to be fixed as one and form long stator structure assembly, thereby make this electromagnetism structure assembly have characteristic on final electricity, magnetic and the mechanics generally with connector.
But this existing technical scheme adopts the form of two moulds, after epoxy is heating and curing technology, in order from mould, to deviate from long stator, hydraulic means under need contracting so just may make the epoxy that is in soft state drop in the dies cavity, directly causes the epoxy distortion.Simultaneously, in the demoulding, also cause the situation of damaging epoxy to take place easily.In addition, when the cast step,, make that the viscosity of epoxy casting material is very high owing to added curing agent and silica flour in the epoxy resin, mobile poor in mould; And owing in casting process, have gas inevitably and be present in the cast liquation, thereby can form the air bubble-shaped defective on the surface of long stator, and cause local epoxy layer thin partially, reduce its corrosion resistance.
Summary of the invention:
The technical problem to be solved in the present invention is to overcome above-mentioned the deficiencies in the prior art, and the method for continuous production of the linear synchronous motor long stator of a kind of effective solution epoxy damage and blibbing problem is provided.
Technical solution main points of the present invention are: a kind of method for continuous production of linear synchronous motor long stator comprises the following steps: step 1: have the electric steel plate of binding agent to go out the electrical sheet with certain cross sectional surface-coated; Step 2: a plurality of electrical sheet pressurizations are formed a lamination bag; Step 3: this lamination bag is heat-treated, bonding agent is solidified to form iron core; Step 4: iron core is adorned mould; Step 5: at the outside one deck epoxy layer that forms of iron core, be characterized in: step 2 is these a plurality of electrical sheets to be inserted in the closed assembly mould pressurize again; Step 3 is lamination bag and closed assembly mould one to be coexisted heat under 140 ℃～220 ℃ temperature, and keeps 0.4～4 hour, and the demoulding forms the iron core with good stiffness and intensity again; Step 4 is that iron core is packed in three moulds; Step 5 is in a vacuum iron core to be formed one deck epoxy layer.
These three moulds are made of patrix, left half module and right half module.
Dress mould in the step 4 comprises following process: insert the dovetail shaped connector in the upper notch of iron core, by bolt the patrix of connector and three moulds is coupled together, iron core is lifted on the patrix;
Patrix and iron core are placed on the support; Spraying contains silica-based release agent on the inner surface of the clean left and right sides half module of cleaning; Again left and right sides half module is closed up, again patrix and left and right sides half module are connected to one by bolt;
With three moulds behind iron core, the matched moulds being housed in 160～200 ℃ furnace temperature, three moulds and iron core are preheating to more than 100 ℃, put into a vacuum chamber then.
Step 5 is to come the outside cast formation of the iron core in being in vacuum chamber one deck epoxy layer by running gate system, and its detailed process is as follows:
By flexible pipe the vacuum degree of mould and vacuum chamber is evacuated to below the 1000Pa with vacuum pump;
After the epoxy packages material stirred, put into running gate system, the temperature of running gate system keeps stirring in running gate system and suitably vacuumizing less than 100 ℃, removes bubble wherein, is pressurized to 1～6kgf then, can not stir during pressurization;
Open the valve that connects the epoxy running gate system, the state that maintenance vacuumizes, begin to carry out epoxy casting then, after epoxy appears in the emitting of vacuum system to be connected, close the valve of vacuum system, stop epoxy casting, the valve of epoxy casting system stays open state, the valve of running gate system is closed in pressurize 1～30 minute again, stops cast;
After stopping cast, open vacuum chamber, removal connects flexible pipe, with three moulds and the iron core that is enclosed with epoxy layer are in vacuum chamber, shift out, put into heating furnace, in the environment about 100～200 ℃, after solidifying about 1～10 hour, in stove, mould is shifted out, cool off.
To be cooled after 40～100 ℃, three moulds and the iron core that is enclosed with epoxy layer are together placed and are fixed on the fixed mount; Throw off earlier left and right sides half module, again the iron core that is enclosed with epoxy layer pulled down from fixed mount together with patrix, be placed on the curing mold, the removal patrix, again with long stator in 100～200 ℃ temperature environment, solidified about 1～20 hour.
Linear synchronous motor long stator method for continuous production of the present invention, by adopting the form of three moulds, carry out epoxy casting at vacuum chamber, each operation is carried out temperature control, and control corresponding vacuum degree or pressure etc., solved problems such as the demoulding of the prior art and bubble effectively.
