According to the output of stamping parts of motor housing, the more hoists are selected, the better. However, considering the size of material box and the cost of the whole automatic disc loading equipment, the equipment cost is reduced as far as possible on the premise of meeting the production demand. Therefore, two crawler type inclined lifting conveyors are selected for the project. The elevator is built in the silo. The upper end of the elevator is connected with the pipeline by a screening device to identify and screen the stamping parts of the motor housing in the positive and negative directions, so that the stamping parts of the positive motor housing can smoothly enter the pipeline. The stamping parts of the negative motor housing slide out of the screening leak and return to the silo. The other end of the pipeline is fixed in the lead-in pipe of the rack platform.

The utility model relates to a three opening lost foam mold for a motor shell. The mold mechanism comprises an automatic feeding gun, an upper mold, a side core pulling insert, a core pulling cylinder, a lower mold, a lower mold, an upper mold core, an upper mold sealing plate, a positioning plate and a spring mechanism.

Improving the quality of Dalian motor shell blank

During the processing and assembly in the production workshop, it often happens that the workpiece cannot be assembled in place. Most of these cases are caused by the out of tolerance of the overall dimension of the motor shell, the large foot root and the height of the non mating surface higher than the processing plane. This situation not only increases the difficulty of assembly, but also increases the maintenance workload. We need to strengthen the quality control of the motor shell blank, and also consider modifying the mold to reserve a little space.

For the motor equipped with rolling bearings, remove the bearing outer cover first, then loosen the fastening screws of the end cover, mark the joint between the end cover and the base shell (the marks of the front and rear end covers should not be the same), screw the removed fastening screws of the end cover into the two specially set screw holes on the motor end cover, and push the end cover out. For motors without such screw holes, only chisels (also known as flat shovels) and hammers can be used to knock the joint between the end cover and the base to remove the end cover from the base. If the end cap is heavy, lift the end cap with lifting equipment and remove it gradually.

The motor shell heater can heat various metal motor shells, such as cast iron shell, steel plate shell, stainless steel shell, etc. generally, cast iron shell is used for motors, stainless steel shell is used for high-speed motors, and steel plate shell is commonly used.
