Abstract
The invention relates to dropping varnish technical field in electric machine manufacture, especially an improved electric machine rotor dropping varnish process comprising preheating the workpiece: setting the preheating area tempreture of the tunnel type dropping varnish machine at 80-100 DEG C when the ambient temperature is higher than 30 DEG C, setting the preheating area tempreture of the tunnel type dropping varnish machine at 135 DEG C when the ambient temperature is lower than 10 DEG C; dropping varnish to the workpiece when the workpiece dropping varnish position temperature is controlled at 90+/-5 DEG C; solidifying the workpiece, setting the solidifying area tempreture of the tunnel type dropping varnish machine at 135 DEG C when the ambient temperature is higher than 30 DEG C, setting the solidifying area tempreture of the tunnel type dropping varnish machine at 145 DEG C when the ambient temperature is lower than 10 DEG C; taking out the workpiece to standby after completing the dropping varnish, clearing the surface redundant varnish to put into next process. Compared with the prior art, the invention can adjust the dropping varnish parameter based on the ambient temperature and ensuring the workpiece product quality.
Description
[technical field]
The present invention relates to dripping in the motor manufacturing and coat with lacquer technical field, specifically a kind of improved technique for painting electric machine rotor.
[background technology]
Because motor rotor runs up and descend temperature higher in working order, need wrap a unsaturated polyester varnish at the rotor line reinforces and the reinforced insulation performance, yet, if the residing space of trickle impregnation machine does not have the efficient temperature control appliance, in the winter time with summer the temperature difference can reach more than 40 degree, very be unfavorable for dripping the carrying out of lacquer, temperature is crossed the low malabsorption that can cause workpiece to lacquer, when high rotating speed used, enamelled wire can fly out from groove; Temperature is higher, can reduce the flowability of lacquer, produces bubble or stops up peristaltic pump, must regulate the viscosity, temperature etc. of trickle impregnation machine preheat temperature, curing temperature and lacquer according to ambient temperature.
[summary of the invention]
Purpose of the present invention overcomes the deficiencies in the prior art exactly, adjusts the parameter of technique for painting according to ambient temperature, carries out quantitative management, eliminates variation because of ambient temperature to the physics of lacquer, the influence that chemical property produces, and guarantees product quality.
For achieving the above object, design a kind of improved technique for painting electric machine rotor, it is characterized in that: (1) workpiece preheating: when ambient temperature is higher than 30 ℃, the preheating zone temperature of tunnel type trickle impregnation machine is arranged on 80-100 ℃, when ambient temperature is lower than 10 ℃, the preheating zone temperature of tunnel type trickle impregnation machine is arranged on 100-110 ℃ workpiece carried out preheating; (2) drip lacquer: workpiece drips lacquer place temperature and is controlled at 90 ± 5 ℃, and workpiece is dripped lacquer; (3) solidify: when ambient temperature is higher than 30 ℃, the curing area temperature of tunnel type trickle impregnation machine is arranged on 135 ℃, when ambient temperature is lower than 10 ℃, the curing area temperature of tunnel type trickle impregnation machine is arranged on 145 ℃; (4) taking-up is standby: after a lacquer is finished, workpiece is taken out, the surperficial unnecessary lacquer of cleaning changes next procedure over to.Employed when sealing 1.15 times of the viscosity of sealing lacquer when lacquer makes its viscosity greater than 20 ℃ because of ambient temperature in the described technique for painting step, the temperature that then adopts cooling device will seal lacquer remains on below 35 ℃.
The present invention compares with prior art, can drip the parameter of lacquer according to the ambient temperature adjustment, is convenient to quantitative management, eliminates variation because of ambient temperature to the physics of lacquer, the influence that chemical property produces, and guarantees the workpiece product quality.
[embodiment]
Below the invention will be further described.
Adopt following processing step that the rotor line is dripped lacquer:
Workpiece carries out preheating: when ambient temperature is higher than 30 ℃, the preheating zone temperature of tunnel type trickle impregnation machine is arranged on 80-100 ℃, when ambient temperature is lower than 10 ℃, the preheating zone temperature of tunnel type trickle impregnation machine is arranged on 100-110 ℃ rotor carried out preheating;
Drip lacquer: the temperature that workpiece drips the lacquer district is controlled at 90 ± 5 ℃, and workpiece is dripped lacquer, and when ambient temperature made the viscosity of sealing lacquer seal 1.15 times of viscosity of lacquer during greater than 20 ℃, the employing cooling device remained on the temperature of coating with lacquer below 35 ℃.
Solidify: when ambient temperature is higher than 30 ℃, the curing area temperature of tunnel type trickle impregnation machine is arranged on 135 ℃, when ambient temperature is lower than 10 ℃, the curing area temperature of tunnel type trickle impregnation machine is arranged on 145 ℃;
Take out standby: after a lacquer is finished, workpiece is taken out, the unnecessary lacquer in cleaning surface changes next procedure over to.
