Embodiment Construction
[0015] The processing method of the small and medium-sized motor frame of the present invention comprises the following steps:
[0016] The first step is to cast the workpiece, and use the casting method to cast the workpiece blank;
[0017] The second step, heat treatment, adopts the annealing process to anneal the blank. When the workpiece is annealed, the furnace temperature is below 300°C and enters the furnace. After the workpiece enters the furnace, the furnace cavity is closed, and the heating rate is controlled within the range of 100-150°C / h. ,, when the furnace temperature rises to 550°C-650°C for the steel plate machine base, keep warm within this temperature range for 1-2 hours; when the cast iron machine base rises to 500°C-550°C, keep warm for 4 hours within this temperature range ~6 hours, after the heat preservation time is reached, the workpiece is cooled with the furnace, and the temperature drop rate in the furnace chamber does not exceed 100°C / h. If the...
