一种氩弧焊焊丝送丝夹持装置
本技术一种氩弧焊焊丝送丝夹持装置,涉及一种在进行氩弧焊焊接时,对焊丝进行夹持固定防止焊丝回位脱落的装置,属于机械加工领域。特别涉及一种通过调节压缩弹簧的压缩量,来挤压夹套对焊丝进行夹持的防止焊丝脱落装置。
技术介绍
目前,在进行机械加工焊接时,为了确保焊接质量,会采用氩弧焊,氩弧焊在焊接时,焊丝通过送丝机送入,并通过焊枪进行焊接送出,由于氩弧焊的焊丝都是通过送丝管进行送入,焊枪的移动范围有限,在焊接过程中,会穿线焊丝受力断裂在送丝管内,使得焊丝在进行重新牵引时困难,有的甚至会沿着送丝管往回收缩,导致焊丝需要重新进行牵引送丝,虽然现有的送丝机都能够单独的进行送丝回收回,但送丝效率低,耽误焊接时间,使得焊接位置温度下降,影响焊缝质量,不能够在焊丝断裂时对焊丝进行单向的夹持固定,现有的一侧单向夹持固定通过电磁阀进行,在进行夹持时,会造成压痕,再次出现断裂,且不同焊丝所需要的夹持力不同,不能进行调节有针对性的进行夹持固定,影响焊丝的送丝防脱。
