An automatic processing technology for die-casting aluminum rotor of ceiling fan motor

Abstract

The invention discloses an automatic processing technology for die-casting aluminum rotors of ceiling fan motors, comprising the following steps: pouring aluminum alloy materials into a melting furnace and heating to a set temperature; die-casting and forming the motor rotors through die-casting molds; The motor rotor with the handle behind the mold is taken out from the die-casting mold and put into the punch; the punch punches the handle off the motor rotor, and the removed handle falls from the punch and flows onto the conveyor belt , and automatically returned to the furnace through the conveyor belt. At the same time, the palletizing robot takes out the punched motor rotors in the punching machine and stacks them on the receiving rack in an orderly manner; repeat the above steps to realize the continuous automatic production of the motor rotors. Realize automatic production from die-casting molding, removing die-casting parts from the die-casting mold and moving them to the punching machine, punching the material handle, stacking the punched motor rotors in an orderly manner, and returning the material handle to the furnace, with high production efficiency. The fluctuation of furnace temperature is small, and the production yield is high.

AI Technical Summary

Problems solved by technology

The die-casting production of the existing motor aluminum rotor is usually produced by a manually operated die-casting machine. Due to the rest of the staff in the middle of each shift, the mold temperature will drop, resulting in unstable mold temperature and large temperature fluctuations, resulting in a high defect rate of aluminum rotor castings.

In addition, the existing ceiling fan industry motor aluminum rotor die-casting die-casting motor aluminum rotor often has poor warping and deformation, and is not dense enough, the gravity of each part is uneven, and the instability of the mold temperature will lead to the aggravation of the above problems. It is very easy to generate electromagnetic noise, and uneven gravity can easily cause noise when the ceiling fan motor is working. Die-casting molds generally use side-to-side pouring, and the side-to-side die-casting pressure is too large. After the casting is formed, many products will have a slight ellipse. Follow-up Turning will cause more turning on one side and less turning on the other side, which will also cause uneven gravity of the rotor and generate noise

After the die-casting of the aluminum rotor of the motor, the die-casting is manually taken out from the die-casting machine. At this time, the die-casting includes two parts: the aluminum rotor of the motor and the material handle. The jig folds the material handle from the aluminum rotor of the motor. Since the material handle is located on the side of the aluminum rotor of the motor, it is easy to fix. Usually, the material handle is fixed by a clamp, and then the aluminum rotor of the motor is moved to make the two from the connection. This production method is likely to cause deformation of the aluminum rotor of the motor, which eventually leads to the generation of rotor noise

[0003] In addition, after the material handle is broken, the material handle is usually collected manually and then returned to the furnace for reuse. Because the temperature of the furnace is very high, the manual feeding work is intensive when returning to the furnace, and the weight of each feeding is different, resulting in fluctuations in the temperature of the furnace. , and after adding a large amount of handle suddenly, the temperature will drop sharply, these operations will reduce the yield rate

[0004] Due to the limitations of the existing manufacturing process, the current aluminum rotor die-casting mold for motors is usually a one-out-one structure to reduce the probability of defective products. Some companies also try to make one out of two, but the technical difficulties have not been overcome, and the defectiveness is too high. ended in failure

[0005] The existing production method of aluminum rotors for motors requires a lot of manpower, the production personnel work hard, the production efficiency is low, and the yield rate of aluminum rotors for motors is also low, which makes the quality stability of aluminum rotors for motors processed by subsequent vehicles poor.
