Description

Motor lamination burring device

Technical Field

The utility model relates to a mechanical device processing technology field specifically is a motor core burring device.

Background

The gas water heater on the market at present is different from the old flue type water heater, and the burning is in airtight combustion chamber, and quick burning companion can produce a large amount of used heat, just needs to use the fan to carry out waste gas exhaust to the water heater and what the fan needs the motor to provide power, and the motor comprises other accessories such as stator, rotor and punching. The punching sheet is usually manufactured by a punching process, and because burrs are remained on one surface of the punching sheet, the motor stator punching sheet has overlarge burrs, so that the quality and the electrical performance of the whole motor are seriously damaged. The iron core lamination coefficient is reduced due to the fact that the burrs are too large, and the electric performance is influenced as the weight of the stator iron core is not enough. The excessive burr makes the elastic opening of the stator core tooth part larger than an allowable value, which can cause the reduction of power factor, the increase of copper consumption and the increase of temperature rise. After the stator is pressed and assembled, short circuit occurs between the stator punching sheets, eddy current loss is increased, meanwhile, the outer circle of the stator core is uneven, the contact area with the base is reduced, heat conduction is affected, and the temperature rise of the motor is increased. The control of the burrs of the stator punching sheet is very important for improving the quality of the whole motor.

The existing main methods for punching the motor are as follows: firstly, the existing deburring device for the motor mostly adopts a deburring roller to remove burrs, the stator punching sheet can be bent and deformed in the deburring process, and if the friction force is too small, the deburring is not clean, so that the deburring device is difficult to control in operation, the stator punching sheet is easy to damage, and the edge after the burrs are removed is easy to remain and is not smooth; and secondly, the trimming of the stamping die is realized, the deburring is carried out according to different products, namely different rough dies, fine stamping dies and the like, the reuse rate of the stamping die is low, the stamping die is only suitable for products with simpler parting, and the manufacturing cost is correspondingly improved.
