Abstract

本实用新型公开了一种防脱落钢芯,它包括钢芯,在钢芯的外表面背靠背方向加工有凸起的倒刺。所述倒刺的材料采用不锈钢制作。本实用新型具有以下效果:利用鱼钩倒刺的原理加工出钢芯,将钢芯装入铝管后倒刺能够卡住铝管壁,从而起到防止钢芯的脱落。

Description

一种防脱落钢芯
技术领域:
本实用新型涉及一种防脱落钢芯,特别适用于家电制冷行业冰箱、冷柜及蒸发器中氩弧焊焊接时使用。
背景技术:
现有的钢芯是一根圆柱形不锈钢管,因钢管采用的是不锈钢,其表面较为光滑,将此钢芯装入钢管中,如受到颠簸,振动时会导致钢芯脱落,从而造成氩弧焊接时焊点堵塞。
发明任务:
本实用新型的任务是提出降低产品报废、提高产品质量的一种防脱落钢芯。本实用新型的任务是这样完成的,它包括钢芯,其特征在于:在钢芯的外表面背靠背方向加工有凸起的倒刺。所述倒刺的材料采用不锈钢制作。本实用新型具有以下效果:利用鱼钩倒刺的原理加工出钢芯,将钢芯装入铝管后倒刺能够卡住铝管壁,从而起到防止钢芯的脱落。
附图说明:
图1是现有技术结构示意图;图2是本实用新型的结构示意图。
具体实施方式:
结合以上附图详细描述实施例,在钢芯的外表面背靠背方向加工有凸起的倒刺2,倒刺的材料可以选用不锈钢片,将此钢芯装入铝管后倒刺自身受到铝管壁的挤压,因不锈钢片具有良好的刚性和柔韧性会产生一种反作用力,利用倒刺的特征卡紧钢管壁,从而防止了钢芯的脱落。

Claims (2)

1.一种防脱落钢芯,它包括钢芯,其特征在于:在钢芯的外表面背靠背方向加工有凸起的倒刺。
2.根据权利要求1所述的一种防脱落钢芯,其特征在于:所述倒刺的材料是不锈钢制作。
