Anti-blocking metalworking practice teaching steam engine model

Abstract

The invention discloses a metalworking practice teaching steam engine model with the air output capable of being adjusted. The model includes a base which is used for installing a heating furnace bracket and a steam engine bracket, a heating furnace which is fixedly installed on the heating furnace bracket and used for steam output, and a heating furnace which is provided with three air outlets. The model has the advantages that the structure is reasonable, the principle of the steam engine model is simpler than that of a double-acting steam engine model, and for college students who are new to mechanical principles, the principle of mechanical transmission is easier to understand through the steam engine model; when a steam-cylinder piston is stuck in the limiting position due to the lack of steam inertial power, the students can be guided to analyze the reason of being stuck, then by installing a balance bar, the wall of a foaming ring is pushed to swing forwards by using airflow power of exhaust of the steam engine, and then the steam-cylinder piston is driven to smoothly pass through the limiting position; and the students are guided to think deeply and propose own solutions, and imagination and creative thinking of the students are inspired.

Description

technical field [0001] The invention relates to a teaching auxiliary device, in particular to an anti-blocking metalworking practice teaching steam engine model. 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....
