Abstract
An automatic expanding technology for shaping the frame-type windings of stator is disclosed. A mandrel with expanding arms is used as the expanding center of the expanding mechanism. Two straight fixtures is used to directly shape two straight lines and to fix two straight sides of winding. The straight expanding fixtures are fixed to two expanding arms respectively. Two expanding arms rotate around the mendrel to ensure the parallelism of two straight sides of the winding. A special arc die is used to automatically shape the winding by predefined arc.
Description
The invention belongs to a kind of coil of stator of motor processing technology thereof and equipment, be mainly used in all size asynchronous traction motor stator coil bulging shaping usefulness, also can be used for alternating current machine stator coil once-forming and end bending.
Stator frame coil many expanding machines with once-forming when manufacture craft is strict are made and are shaped, when particularly making asynchronous traction motor stator frame coil for usefulness corona-resistant polyimide electromagnetic wire, because manufacture craft requires very strict, in forming process, forbidden to strike, forbidden to beat, and do not wish to use again complex mould complex after being shaped, in case the insulating properties of coil is influenced, so this class stator frame coil is fully by automatic forming of the automatic expanding machine of stator frame coil.But because existing stator frame coil spreading machine is when coil straight line bulging, be the center normally with two axle center, two straight lines of coil constitute two straight lines in space by four bulging fixture blocks, and be that two straight lines that rise into by coil are outwards rotated at the center with the axle center of two axles respectively, and by two groups of nose clips the coil both ends are stretched in the end along another axle center simultaneously, form the end limit by top arc mechanism top arc again.Though this manufacture craft has realized the purpose that disposable bulging is shaped, but because the coil straight line of this manufacture method is two straight lines that are configured to the space with four bulgings, and be again respectively around two axle center rotary formings, this just is difficult to guarantee that coil two straight lines remain in the course of processing parallel, and the axle center that just in time aligns motor after being shaped of straight line.Straight line is stressed stressed not at grade with the end hypotenuse.And the end formed of existing expanding machine is to adopt top arc mechanism top arc to be shaped.Phenomenons such as bulge, crackle very easily appear, thus be difficult to guarantee that coil forming does not need the technological requirement of complex again, and must not behind coil forming, re-use complex mould complex.To greatly influence the quality of coil so again, and reduce the qualification rate of product, therefore, the utmost point remains to be improved.
The objective of the invention is to deficiency at the existing automatic bulging Processes and apparatus of stator coil, it is effective to propose a kind of bulging, do not need complex again after the bulging, and bulge can not appear at turning, bulging process cathetus limit, the automatic bulging Processes and apparatus of novel stator coil of crackle, the partly automatic curved arc of end hypotenuse.
The objective of the invention is to be achieved by following technical proposals, adopt the arm axle that rises, each bulging mechanism all with same single mandrel as bulging center bulging, and with the method for four two straight lines in space that arm constitutes that rise of fixed coil two straight lines, change into by two linears anchor clamps that rise and directly form space two straight lines, and with two straight lines of this anchor clamps fixed coil, the linear expanding fixture is contained in respectively on the arm that rises of two mandrels, two rise by arm when bulging, simultaneously around same axle to the inner rotary bulging, so just be easy to guarantee that coil two straight lines remain parallel in the bulging process, exactly because also two straight lines of coil are all the time round same axis heart rotation bulging, and this axle center and electrical axis are same axle center, thereby two straight lines that can guarantee coil all the time are towards electrical axis, so just guarantee product quality fully, when preventing subsequent processing motor coil rule, four angles of coil are scratched in the rule process.In addition, the part at coil two ends is to be clamped by nose clip, and the solid frame of nose clip is on the nose clip frame, and the nose clip frame is installed on the nose clip stand, and the nose clip stand is contained in the nose clip rising mechanism, and is placed on the guide rail of lathe bed by nose clip rising mechanism.And special curved arc mould is housed on nose clip, in the bulging process, adopt the bag arc bulging technology of non-top arc, by special curved arc mould on the nose clip, in the bulging process, adopt the bag arc bulging technology of non-top arc, determine that by special curved arc mould on the nose clip the good automatic curved arc of radian is shaped in bulging in advance.Adopting straight line that the spacing space of the straight line clamp ends of particular design guaranteed coil and the switching of end arc to be in the bulging process four jiaos seamlessly transits.
This product is shaped with a novel bulging utilizing a single mandrel to realize stator frame coil dexterously, the centering that can avoid two axle center to bring effectively is inaccurate like this, be difficult to guarantee the coil straight line all the time towards a series of problems that electrical axis produced, thereby can prevent that the coil of stator of motor phenomenon that four angles of coil are scratched when rule from occurring.Improved the phenomenon appearance that four angles of the qualified coil of stator coil in the rule process are scratched greatly.Improved the qualification rate of stator coil in the rule process greatly.And owing to adopted bag arc technology generations to replace top arc technology, and adopt stopping means to guarantee that coil can seamlessly transit for four jiaos in the bulging process in coil straight line corner, not bulge, stator coil after the bulging does not need complex again, this has further improved the quality of coil spreading again, make the coil of bulging meet the requirement of the stator coil forming technology of 200 grades of corona-resistant insulation structures fully, realized once automatically complete bulging, do not strike and do not beat, automatic curved arc, and do not need multiple high performance requirements such as complex after being shaped, improved the reliability that coil uses, the stator coil that states such as present technique and West Europe and Japan are current and the improvement synchronised of wire insertion technology, and technical characterstic is respectively arranged, reach the international leading level.Employing should be widely promoted.
