一、抛砂机的使用特点与现状抛砂机是以高速旋转的叶片,将型砂抛入砂箱,得到紧实铸型的造型设备。它以机械代替人工加砂与捣实,一般每小时可抛砂12—15米~3/,比手工生产效率提高3-10倍。这就大大地提高了劳动生产率,减轻了工人体力劳动。而且由于抛出铸型紧实度均匀,从而也提高了铸件的质量。抛砂机主要的特点是适应性强,对大小高低不同的砂箱均可抛制,也能抛制型芯。工艺装备要求不高,即使手工造型用的也可使用。这对各类大小铸件,各种批量生产,尤其对不易实现机械化的单件小批生产的大甲型铸件,是较好的方法。此外,抛砂机还
First, the use of sand throwing machine characteristics and status Sand throwing machine is a high-speed rotation of the leaves, the sand thrown into the sand box, get a tight molding equipment modeling. It is a mechanical alternative to artificial sand and tamping, the general throwing sand per hour 12-15 m ~ 3 /, than the manual production efficiency increased by 3-10 times. This has greatly increased labor productivity and alleviated the manual labor of workers. And because the casting mold solidity uniform, which also improves the quality of the casting. Sand throwing machine is characterized by the main adaptability, the size of different sand boxes can be cast, but also cast core. Process equipment is not demanding, even if the manual modeling can also be used. This is a good method for all kinds of castings of various sizes, all kinds of mass production, especially for large-size castings that are not easy to realize mechanized single-piece small-batch production. In addition, throwing machine also
