Description

Technical Field

[0001] The utility model relates to the technical field of steel casting cutting, in particular to an edge cutting device for producing steam turbine steel castings. Background Art

[0002] A steam turbine, also known as a steam turbine engine, is a rotary steam power device. High-temperature and high-pressure steam passes through a fixed nozzle to become an accelerated airflow and is then sprayed onto the blades, causing the rotor equipped with the blade rows to rotate and perform work externally. Steam turbines are the main equipment in modern thermal power plants and are also used in the metallurgical industry, chemical industry, and ship power plants. During production, the edge surfaces of steam turbine castings will have risers and burrs, so these risers and burrs need to be removed by external cutting equipment.

[0003] For example, the invention patent CN109865883B discloses a "reciprocating steel plate cutting device based on the crank slider principle". When cutting steel, due to its structural limitations, its reciprocating range is small, resulting in a small range of use, and it can only perform horizontal cutting. When performing horizontal cutting, the steel needs to be pushed manually, and it cannot cut the steel vertically. It needs to cooperate with manual rotation or flipping of the steel to complete the vertical cutting work. After the steel is rotated or flipped manually, the position of the steel needs to be adjusted. Not only does it require a lot of physical strength from the workers, but also manual rotation, flipping and adjustment of the steel position will waste a certain amount of time, thereby reducing its cutting efficiency.
