Abstract

盾构机用可旋转撕裂刀的硬质合金头属于盾构机刀具领域，它由球R体1，截圆锥体2，圆柱体3，过渡体4，钎焊柄5，筋6组成，在钎焊柄5和过渡体4的外周上设置有均布的五条外凸筋6，采用上述结构后，五条外凸筋6的外周与刀体7孔的内周可设置为极小间隙配合，使安装钎焊过程中定位精度高，钎焊层厚度均匀，钎焊牢固，保证了刀具使用寿命。

Description

盾构机用可旋转撕裂刀的硬质合金头
技术领域
盾构机用可旋转撕裂刀的硬质合金头属于盾构机用刀具领域，是易磨损零件。
背景技术
地铁隧道、矿山、水利等工程中，广泛应用盾构机的撕裂刀、中心刀、刮刀、滚刀等刀具施工，对岩石、泥土、砂砾等地层开沟撕裂、碾轧、破碎和刮削，其中撕裂刀主要是对地层开沟撕裂。现在的撕裂刀上面的硬质合金头，钎焊柄和过渡体的外周上没有筋，因钎焊柄的外周与刀体孔的内周需要大间隙配合，安装钎焊过程中，易出现钎焊层厚度不均匀，钎焊不牢固的缺陷，需要改进其结构。
实用新型内容
本实用新型的目的是提供一种使钎焊层厚度均匀，钎焊牢固的盾构机用可旋转撕裂刀的硬质合金头，从而保证刀具使用寿命，它由球R体，截圆锥体，圆柱体，过渡体，钎焊柄，筋组成，钎焊柄和过渡体的外周上设置有均布的五条外凸筋，采用上述结构后，五条外凸筋的外周与刀体孔的内周可设置为极小间隙配合，使安装钎焊过程中定位精度高，钎焊层厚度均匀，钎焊牢固，保证了刀具使用寿命。
附图说明
说明书附图为盾构机用可旋转撕裂刀的硬质合金头的结构示意图，其中图1为主视图，图2为图1的仰视图，图3为图1中A-A的剖面图，图4为其与刀体的安装钎焊示意图，剖面位置也在图1中的A-A。
附图中，1是球R体，2是截圆锥体，3是圆柱体，4是过渡体，5是钎焊柄，6是筋，7是刀体，8是钎焊层。
具体实施方式
下面结合附图对盾构机用可旋转撕裂刀的硬质合金头的实施例作详细说明。
如图1、图2、图3所示，盾构机用可旋转撕裂刀的硬质合金头，由球R体1，截圆锥体2，圆柱体3，过渡体4，钎焊柄5，筋6组成，在钎焊柄5和过渡体4上设置有均布的五条外凸筋6，又如图4所示，钎焊柄5和过渡体4安装钎焊于刀体7的孔中，采用上述结构后，五条外凸筋6的外周与刀体7孔的内周可设置为极小间隙配合，使安装钎焊过程中定位精度高，钎焊层8厚度均匀，钎焊牢固，保证了刀具使用寿命。
