Abstract

本实用新型涉及机械领域,尤其是用于粉煤热压预成型的螺旋挤压机的螺旋轴。其特征在于螺旋轴的前部安装有半球状耐磨头和带切向键槽的轴套,轴套上焊有叶片,与螺旋轴上叶片对接,半球状耐磨头与轴套焊接成一体,切向键上设有螺孔,用螺钉将切向键固定在螺旋轴上的切向键槽内。特点是增强了螺旋挤压机的螺旋轴的轴头及端部螺旋的耐磨性,延长了螺旋轴的使用寿命,带半球状耐磨头的轴套可以拆卸,便于更换。

Description

带耐磨头和轴套的螺旋轴
本实用新型涉及机械领域,尤其是用于粉煤热压预成型的螺旋挤压机的螺旋轴。
现有技术中,申请号为94230186.2的实用新型专利《用于粉煤热压预成型的螺旋挤压机》提供一种用于粉煤热压预成型的螺旋挤压机,其特征是在螺旋轴上的螺旋叶片径向边沿镶焊或铆接耐磨硬质合金块或淬火后的高速钢条,衬套内槽插镶淬火后的高速钢条形成耐磨的内表面,该结构提高了设备的使用寿命,但螺旋轴前部耐磨性差。
本实用新型的目的是提供一种前部带耐磨头和轴套的螺旋挤压机的螺旋轴。
本实用新型内容简述:
一种用于粉煤热压预成型的螺旋挤压机的螺旋轴,其特征在于:螺旋轴的前部安装有半球状耐磨头和带切向键槽的轴套,轴套上焊有叶片,与螺旋轴上叶片对接,半球状耐磨头与轴套焊接成一体,切向键上设有螺孔,用螺钉将切向键固定在螺旋轴上的切向键槽内,将轴套的切向键槽套入切向键上,然后用螺钉在轴端将耐磨头与螺旋轴端部固定。
本实用新型的特点是:增强了螺旋挤压机的螺旋轴的轴头及端部螺旋的耐磨性,延长了螺旋轴的使用寿命,带半球状耐磨头的轴套可以拆卸,便于更换。
图1为带耐磨头和轴套的螺旋轴示意图。
下面结合附图给出如下实施例:
螺旋轴6的前部安装有半球状耐磨头1和带切向键槽的轴套7,轴套7上焊有叶片5,与螺旋轴上叶片对接,半球状耐磨头1与轴套7焊接成一体。切向键3上设有螺孔4,用螺钉将切向键3固定在螺旋轴上的切向键槽内,安装时,将轴套7的切向键槽套入切向键3上,然后用螺钉2在轴端将耐磨头1与螺旋轴6端部固定。
半球状耐磨头1及轴套7上的螺旋叶片5外表面喷焊碳化钨合金,厚度1—2mm。
