The invention discloses a vacuum pre-drying device used in a motor immersing process. The device comprises a heating box, a top cover disposed at the top of the heating box, and a fixing device whichis disposed in the heating box. The bottom of the heating box is provided with a heating block, and the top cover comprises a left top cover and a right top cover. The top of the heating box is provided with a support plate, and the support plate is provided with a first drive part which drives the left top cover and the right top cover to make horizontal motion. One side of the heating box is provided with an exhaust tube, and the exhaust tube is connected with an air pump. The interior of the exhaust tube is provided with a sealing device. When a motor stator is placed into the heating box for pre-drying, the motor rotor is baked for a time period through the heating block, and then the exhaust tube performs the vacuum pumping, and then the motor rotor is baked again for a time period, thereby saving the energy, and achieving the pumping of the moisture in a furnace. The boiling point of water decreases under the vacuum pumping condition, and the drying can be performed under lower temperature, so as to alleviate the insulating thermal damages, and improving the pre-drying efficiency of the motor.
Description
technical field [0001] The invention belongs to the technical field of motor production equipment, and in particular relates to a vacuum pre-drying device used in the motor pouring process. Background technique [0002] The winding is the most fragile part in the motor structure. In order to improve the moisture resistance, corrosion resistance and insulation strength of the winding, as well as improve the mechanical strength, thermal conductivity and heat dissipation effect and delay aging, the motor winding after rewinding must be dipped in paint. It is also required that the varnish dipping and drying should be carried out strictly according to the insulation treatment process, so as to ensure good permeability of the insulating varnish, smooth surface of the paint film and high mechanical strength, so that the stator winding can be bonded into a solid whole. The main methods of varnish dipping are: pouring, immersion, vacuum pressure immersion, and dipping of a single re...
