打撈用夯錘是地質勘探用的工具,形狀如图1,这个工具按照苏联設計标准,是用35钢制成。由于鋼材缺乏,苏联專家建議,采用鑄鉄和鍛钢連接的方法来制造該項产品。改进后如图2,1和3是用35钢制造,2是用普通鑄铁来制造,为了使它們能連接在一起,在孔4中穿入φ18公厘的元鉄,然后將兩端鉚死銼平,三件就連为一体了。这样每年可以节約9吨鋼材。制出 Hammer hammer salvage with geological exploration tools, the shape shown in Figure 1, this tool according to Soviet design standards, is made of 35 steel. Due to the lack of steel, Soviet experts suggested that the product be manufactured by joining cast iron and forged steel. Improved as shown in Figure 2, 1 and 3 are made of 35 steel, 2 is made of ordinary cast iron, in order to enable them to be connected together in the hole 4 into the φ18 mm yuan 鉄, and then both ends riveted Death file level, three even as one.
