Abstract: A ripper tool for a tunnel boring machine includes a tool body and a plurality of cutting element inserts. The tool body has a plurality of socket cavities. A tool body blank can be heat treated to increase the hardness of the tool body blank. The socket cavities can be machined in the tool body blank after the tool body blank is heat treated. The cutting element inserts are mounted to the tool body. The cutting element inserts are respectively press fit in the socket cavities. The ripper tool can be pivotably mounted to a cutter head of the TBM.

Abstract translation: 用于隧道掘进机的松土工具包括工具主体和多个切割元件插入件。 工具主体具有多个插座空腔。 可以对工具坯体进行热处理，以增加刀体坯料的硬度。 在工具主体坯料进行热处理后，可以在工具主体坯料中加工插座空腔。 切割元件插入件安装到工具主体上。 切割元件插入件分别压配合在插座腔中。 松土工具可以可枢转地安装到TBM的刀头上。
