我厂的熔模精密铸造车间,自去年起开始生产自行车中接头(五通)及其它小型零件。形状复杂的自行车中接头喷砂,成了生产上的一大难关。如用立式手动喷砂机喷砂,操作者必须将两只手插在喷砂室里不停地翻动产品,其劳动强度大,效率低,劳动条件差,质量不稳定,不适宜批量生产。故此,去年下半年我们设计制造了一台自滚式喷砂机(如图)。该机克服了上述缺点,减 Our factory investment casting workshop, starting from last year to produce bicycles in the joints (five links) and other small parts. The complex shape of the bike in the joint blasting, has become a major production difficulties. As with the vertical manual sandblasting sand blasting, the operator must be two hands inserted in the sandblasting room constantly turning the product, its labor-intensive, low efficiency, poor working conditions, the quality is unstable, not suitable for mass production . Therefore, in the second half of last year, we designed and manufactured a self-rolling sand blasting machine (pictured). The aircraft to overcome the above shortcomings, minus
