高温、粉尘环境下的大型铸件浇、冒口半自动气割装备设计

Design of Semi-automatic Gas Cutting Equipment for Pouring and Raising Large Castings Under High Temperature and Dust Environment

大型铸件的浇、冒口切割是铸造工艺过程中铸件清理的重要工序。对于大型铸钢件,近年来主要采用天然气或者氧乙炔火焰气割。为了防止铸件浇、冒口气割中产生较大的铸造应力,气割必须在高温环境下进行。由于受高温、粉尘及铸件的结构形状、尺寸的限制,往往只能依靠工人手持特制加长型割枪气割。为减轻工人劳动强度,改善劳动条件,提高气割效率,根据企业要求,设计研制出新式的、多自由度、半自动气割装备,满足了企业的需求,并且申报了国家实用新型专利。

The pouring and riser cutting of large castings was an important process for casting cleaning during the casting process. For large steel castings, natural gas or oxyacetylene flame gas cutting had been used in recent years. In order to prevent the casting gate, result in bigger stress riser gas cutting, gas cutting must be under the environment of high temperature. Due to the high temperature, dust and the structure of the casting shape, size restrictions, often can only rely on workers with special long cutting torch gas cutting. To reduce labor intensity, improve working conditions, improve the efficiency of gas cutting, according to the requirements of the enterprise, develop new, more degrees of freedom, semi-automatic gas cutting equipment were designed. To meet the needs of the enterprise, and applied for the national utility model patents.
