#$%^&*AU2020101341A420200820.pdf#####ABSTRACT The present invention discloses a steam engine model with an adjustable air output for metalworking practice teaching. The model includes a base for installing a heating furnace support and a steam engine support, a heating furnace fastened to the heating furnace support for steam output, and a steam distribution apparatus that can adjust different output speeds of a steam engine. Advantages of the present invention are as follows: The structure is proper, and the steam engine model has a principle simpler than that of a double-acting steam engine model. For the steam engine model, it is easier for college students who have just studied the mechanical principle to understand the mechanical transmission principle. When a cylinder piston is stuck at a limit position due to insufficient steam inertia, the students can be directed to analyze the reason why the cylinder piston is stuck, and then a wall of a foam ring is pushed to swing forward by installing a balance rod and using airflow power of exhaust of the steam engine to drive the cylinder piston to smoothly pass through the limit position, to direct the students to think deeply and propose their own solutions, and inspire the students' imagination and creative thinking.
