Abstract

本实用新型为盾构机滚刀圈用合金块,属于盾构机用刀具领域,采用与圈体弧形相应的硬质合金弧形条,特点是弧形条主要由下体、上体和中间的过渡体组成,上体的上部为圆弧体;上体的厚度大于下体,过渡体在上体和下体之间采用弧形过渡。便于钎焊,钎接牢固,耐磨性强。同时有效提高了弧形条的工作性能,从而提高了整个滚刀圈的使用寿命。

Description

盾构机滚刀圈用合金块
技术领域
本实用新型属于盾构机用刀具领域,具体说是一种用于制作盾构机用滚刀圈的合金块。
背景技术
盾构机用滚刀圈属于盾构机的易损配件,安装在盾构机转动刀盘的滚刀座上。滚刀圈由多块弧形的合金块组成,钎焊在圈体外周上开设的环形内凹槽,形成合金条,用于开挖、掘进等施工。现在的合金条采用方形合金块,钎焊难度大,牢固性差,造成不耐磨损,工作寿命短。
发明内容
本实用新型的目的在于提供一种便于钎焊的盾构机滚刀圈用合金块,使用寿命长。
本实用新型是这样实现的:
盾构机滚刀圈用合金块,采用与圈体弧形相应的硬质合金弧形条,其特征在于:所述弧形条主要由下体、上体和中间的过渡体组成,上体的上部为圆弧体;上体的厚度大于下体,过渡体在上体和下体之间采用弧形过渡。
本实用新型采用上述结构后,由下体、上体和中间的过渡体组成的弧形条,便于钎焊,同时有效提高了弧形条的工作性能,从而提高了整个滚刀圈的使用寿命。增设的纵向筋,也便于钎焊,钎接牢固,耐磨性强。
附图说明
图1为本实用新型的一种结构示意图,图2为图1的侧视图,图3为图1沿A-A的断面图。
附图中,1为下体,2为上体,3为纵向筋,4为过渡体,5为圆弧体。
具体实施方式
下面结合附图对本实用新型的实施例作详细说明。
如图1所示,本实用新型为盾构机滚刀圈用合金块,采用与圈体弧形相应的弧形条,内凹槽的槽形与弧形条相配合,弧形条用硬质合金材料制造,多个弧形条共同钎焊于圈体的环形内凹槽中,形成高强度滚轧环。如图2所示,弧形条的下部为下体1,上部为上体2,上体2厚度大于下体1,中间为过渡体4,过渡体4在上体2和下体1之间采用弧形过渡;上体2的上部为圆弧体5。如图1、3所示,在上体2、过渡体4和下体1组成的弧形条的两个横侧面上分别设置有凸起的纵向筋3,每个横侧面上设置两条或两条以上的纵向筋3,便于钎焊,保证焊缝厚薄均匀。
