Abstract

The invention discloses a steam engine model for metalworking practice teaching. The steam engine model comprises a base for installing a heating furnace bracket and a steam engine bracket, and a heating furnace fixedly installed on the heating furnace bracket for steam output. The steam engine model for metalworking practice teaching has the advantages that the structure is reasonable, compared with a double-acting steam engine model, a principle of the steam engine model is simpler, for university students who have just contacted the mechanical principle, the steam engine model enables the principle of mechanical transmission to be easily understood, when a cylinder piston is stuck at the limiting position due to insufficient steam inertia power, the students can be guided to analyze reasons of being stuck, then, by installing a balance rod, aerodynamic force of the exhaust of the steam engine is utilized to push a foaming ring wall to swing forwards to drive the cylinder piston to pass through the limiting position smoothly, the students are guided to think deeply, own solutions are put forward, and the imagination and creative thinking of the students are inspired.

Description

technical field [0001] The invention relates to a teaching auxiliary device, in particular to a steam engine model used for metalworking practice teaching. Background technique [0002] Metalworking practice teaching plays a vital role in students' understanding and mastering of traditional machinery manufacturing and processing technology and modern machinery manufacturing and processing technology, and it is also an important way to cultivate students' practical ability. [0003] At present, the basic content of metalworking practice includes general lathe, planing, welding, casting, forging, fitter, CAD / CAM, NC milling, NC turning, rapid prototyping and other process knowledge and basic operations. [0004] A steam engine is a reciprocating power machine that converts the energy of steam into mechanical work. It consists of a base, a cylinder, a piston, a connecting rod crank mechanism, a steam distribution device, and a flywheel. The structure is relatively simple. The p...
