Description
Technical field
The present invention relates to motor Parts manufacturing technology field, particularly a kind of hysteresis machine magnet ring annealing device.
Background technology
Hysteresis machine is a kind of synchronous machine having self-starting ability, and the magnetic hysteresis of the magnetic hysteresis rotor be made up of hysteresis material and the eddy current loss of inducting are to produce rotor torque.The rotation of motor is the effect by stator rotating magnetic field, makes rotor produce hysteresis torque, by electric motor starting and operation of pulling in.The characteristic feature of hysteresis machine be moment of torsion large, operate steadily, structure is simple, noise is low, starting current is little, high temperature resistant.In field extensive uses such as instrument and meter, household electrical appliance, automatically control, national defense industry.
The characteristic of hysteresis machine is determined by the hysteresis property of its rotor magnetic ring.In prior art, the manufacture method that magnetic hysteresis rotor is conventional directly becomes rotor to use after adopting the band punch forming reprocessing such as martensite steel, and its magnetic property is low, and the moment of torsion of hysteresis machine is less, and performance is low, cannot meet the instructions for use of special industry.FeCoV magnetic hysteresis alloy has excellent hysteresis characteristic, manufactures magnetic hysteresis rotor with FeCoV magnetic hysteresis alloy, and the moment of torsion of its hysteresis machine is large, and performance is high.But FeCoV alloy is because of high containing Co amount, and elongation is low, adopts band punch forming, it is very large to be drawn into the equal difficulty of processing mode such as pipe or welding; Someone adopt and prepare silk material after Wrapping formed mode, the higher and poor effect of its cost.FeCoV alloy material could obtain good hysteresis property after having to pass through the temper of about 600 DEG C, and after tempering, crisp Qie Ying ﹐ is difficult to reprocessing.Magnetic hysteresis alloy material produces distortion being heated because of tempering heat treatment, and magnet ring ovality changes, and the not good hysteresis property that causes of dimensional accuracy is deteriorated, and rate of finished products is low, thus affects performance and the stability of hysteresis machine, and this is the defect that always exists of prior art just.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above prepared magnet ring and exist, and provides a kind of hysteresis machine magnet ring annealing device.Adopt the magnet ring that this device is produced, ovality is little, and opening is completely closed, and size is accurate, and easy and hysteresis machine rotor case assembles, and greatly improves the moment of torsion of magnet ring, has good hysteresis property.In addition, this apparatus structure is simple, easy to operate, easily realizes.
Above-mentioned task realizes by this way: a kind of hysteresis machine magnet ring annealing device, it is characterized in that by external mold, mandrel and securing member composition, the centre of described external mold is longitudinally provided with the internal diameter nib identical with magnet ring external diameter, whole external mold is engaged by the upper module of symmetry and lower module and forms, fin is provided with outside upper module and lower module two, fin is provided with fastener hole, upper module and lower module are tightened together through fastener hole by securing member, the external diameter of described mandrel is identical with the external diameter of magnet ring, equidistantly on mandrel be provided with several sizes annular groove identical with magnet ring size, whole mandrel is arranged in the nib of external mold, described external mold and mandrel refractory steel are made.
In technique scheme, following measure can also be taked perfect further.
To arrange 4 ~ 7 annular grooves on mandrel, spacing be 3 ~ 5 millimeters proper, to reduce heat treated distortion, ensure precision.
A spacing flange is provided with so that install in mandrel one end.
Described external mold and mandrel are made with containing niobium hot die steel, to ensure not deform in heat treatment process.
The utility model uses like this: first will with magnetic hysteresis alloy band itemize, cutting, preforming has the magnet ring blank of opening to be set in the annular groove of mandrel, then the mandrel that magnet ring is housed is put in half nib of the lower module of external mold, then upper module nib is snapped onto downwards on lower module, its fastener hole is passed by the bolt of securing member, with fastening nuts, upper and lower module and the mandrel that magnet ring is housed are fixed together, finally put into heat-treatment furnace to heat-treat, heat treatment temperature 570 ~ 630 DEG C, temperature retention time 15 ~ 35 minutes, to come out of the stove air cooling, take upper and lower module apart, take out mandrel, deviate from magnet ring just can.
The beneficial effects of the utility model: from structure of the present utility model and using method, due to magnet ring in whole heat treatment process by the external mold made containing niobium hot die steel of same heat proof material and mandrel fix, substantially do not deform, made magnet ring dimensional accuracy is high, ovality is little, greatly improve its moment of torsion (i.e. hysteresis characteristic), thus effectively overcome the weak point that prior art exists always.It is simple that the utility model also has structure, maneuverable advantage.
