Abstract
The invention discloses a casting method for a solid cage rotor, belonging to the technical field of an electric spindle. The casting method comprises the steps of preparation of a sand mold, drying, pouring, cooling and sand cleaning. Liquid copper is poured into a groove in an outer edge surface of the cage rotor inside the sand mold so as to obtain the solid cage rotor. The solid cage rotor cast by the method disclosed by the invention is free of pores and slag inclusion, normal running performances are guaranteed during high-speed running, the solid cage rotor is suitable for the application requirements of the electric spindles with higher rotating speed and larger power, and beneficial technical conditions are provided for developing ultrahigh-speed electric spindles and improving the work efficiency.
Description
[technical field]
The invention belongs to electric spindle technology field, especially relate to a kind of casting method of ultrahigh-speed electricity main shaft cage rotor.
[background technology]
Known, ultrahigh-speed electricity main shaft rotating shaft thinner, the hole of stator is also less, the cage rotor that silicon steel sheet and cage bar cannot be set by the region trochanterica in stator containing district again improves its power, the solid rotor that can only make of pure iron, but the solid rotor power that pure iron is made is less, efficiency is lower, and the quality of production can not guarantee, cannot use high efficiency Production requirement, in order to address the above problem, can on the external diameter of solid rotor, offer the groove of dove-tail form, then brazing is connected in the groove of dove-tail form, , form cage rotor, but can often there is the shortcoming of pore or slag inclusion in this welding method, cause disconnected bar, use and impact is normal.
[summary of the invention]
In order to overcome the deficiency in background technology, the invention discloses a kind of casting method of solid cage rotor, described method, by copper water being poured in sand mold in the Baltimore groove on cage rotor outer edge surface, is obtained solid cage rotor; The solid cage rotor that method of the present invention casts out not only there will not be pore or slag inclusion, in the time running up, guarantee normal behavior in service, be applicable to the instructions for use of higher, the more powerful electric main shaft of rotating speed, increase work efficiency favourable technical conditions are provided for exploitation ultrahigh-speed electricity main shaft.
In order to realize the object of foregoing invention, the present invention adopts following technical scheme:
A casting method for solid cage rotor, comprises and makes sand mold, oven dry, cast, cooling and sand removal, and its concrete steps operation is as follows:
(1) make sand mold
Cage rotor is placed on to the middle part in sandbox, on the top of sandbox, one side arranges cup, the gate of cup lower end is arranged on the outer edge surface of cage rotor, with sand, sandbox is filled up and compacting after exhaust passage is arranged on to the surrounding of sandbox uniformly, make sand mold;
(2) dry
Connect previous step, the sand mold of making is put into high temperature oven, will after mold drying, be taken out by high temperature oven;
(3) cast
Connect previous step, copper water is poured into from the cup of sand mold, copper water is in gate flows into the Baltimore groove on cage rotor outer edge surface, until pouring area is watered full;
(4) cooling
Connect previous step, be cooled to normal temperature by watering the sand mold that fills copper water;
(5) sand removal
Connect previous step, first the sand, cup, gate and the exhaust passage that are cooled in the sand mold of normal temperature are taken out, obtain solid cage rotor.
The casting method of described solid cage rotor, the bake out temperature of the high temperature oven described in step 2 is 600-700 ℃.
The casting method of described solid cage rotor, the copper water pouring temperature described in step 3 is: 9500-1000 ℃.
The casting method of described solid cage rotor, described Baltimore groove is dove-tail form Baltimore groove.
Owing to adopting technique scheme, the present invention has following beneficial effect:
The casting method of solid cage rotor of the present invention, described method, by copper water being poured in sand mold in the Baltimore groove on cage rotor outer edge surface, is obtained solid cage rotor; The solid cage rotor that method of the present invention casts out not only there will not be pore or slag inclusion, in the time running up, guarantee normal behavior in service, be applicable to the instructions for use of higher, the more powerful electric main shaft of rotating speed, increase work efficiency favourable technical conditions are provided for exploitation ultrahigh-speed electricity main shaft.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present invention;
In the drawings: 1, cup; 2, gate; 3, handle; 4, sandbox; 5, exhaust passage; 6, sand; 7, Baltimore groove; 8, cage rotor; 9, pouring area.
[specific embodiment]
Can explain in more detail the present invention by the following examples, disclose object of the present invention and be intended to protect all changes and improvements in the scope of the invention, the present invention is not limited to the following examples:
The casting method of the solid cage rotor described in 1 by reference to the accompanying drawings, comprises and makes sand mold, oven dry, cast, cooling and sand removal, and its concrete steps operation is as follows:
