一、熔模精密铸造的特点我厂生产的增压器有8号、16号、25号、35号、50号等几种,其中除8号增压器为径流式外,其他各种都为轴流式。 8号增压器的三个主要零件:透平叶轮、鼓风叶轮、喷嘴环,因为外形复杂,叶片成扭状,在样品试制时是用整块合金钢装上夹具,在铣床上铣成叶形开档,叶片的扭状则由人工用工具敲出。这样不但浪费大量合金钢材(透平叶轮重量约1公斤,过去锻成整块毛坯时重4公斤左右,材料利用零仅25％),且不能保证质量,机床负荷又很大。为了高速度建设社会主义,使我厂生产的增
First, the characteristics of investment casting Our superchargers have No. 8, No. 16, No. 25, No. 35, No. 50, and several, of which in addition to the No. 8 turbocharger radial run, the other all For the axial flow. 8 Turbocharger of the three main components: turbine impeller, impeller, nozzle ring, because of the complex shape, the blade into a twisted shape, the sample trial is the whole piece of steel fitted with clamps, milling machine milling Leaf-shaped open file, the blade twist is manually knocked out by the tool. This will not only waste a lot of alloy steel (turbine impeller weighs about 1 kg, in the past forged into a whole piece of about 4 kg weight, material utilization only 25%), and can not guarantee the quality of machine tools and a great load. In order to build socialism at a high speed, I will increase the production of our factory
