Abstract

一种旋铆铆杆,主要是旋铆铆杆的铆杆端头是用硬质合金制成的,铆杆的钢铁杆端头上设有一固定凹槽,硬质合金固定在凹槽内。本实用新型与已有技术相比,具有经久耐用、不易磨损的优点。

Description

旋铆铆杆
技术领域:
本实用新型涉及一种五金配件,特别是一种铆铆钉的五金配件。
背景技术:
现有的旋铆机用旋铆铆杆是一端头呈球状凹坑状或其它与铆钉相配的形状的钢铁杆,端头经热处理处理以便提高其硬度。使用时,在旋铆机的带动下,旋铆铆杆上的球状凹坑将铆钉的杆压塌成伞状。此种旋铆铆杆由于铆杆端头的材质是用一般的钢铁经热处理后制成的,在冷态下,是有足够的硬度将铆钉压塌,但事实上由于旋铆铆杆是在旋铆机的带动下高速旋压在铆钉的杆上,不可避免地会因摩擦发热使铆杆头处于高温状态,而钢铁在高温下会变软,硬度会急速下降,导致铆杆头磨损厉害而损坏,影响了旋铆铆杆的使用寿命。
发明内容
本实用新型的发明目的在于提供一种经久耐用、不易磨损的旋铆铆杆。
本实用新型是这样实现的,主要是旋铆铆杆的铆杆端头是用硬质合金制成的。工作时,基于硬质合金的耐热性能,铆杆在旋压铆钉时,硬质合金不会在高温下变软、磨损。
这里,在旋铆铆杆的钢铁杆端头固接一硬质合金而成。这样,既保证旋铆铆杆端头在工作时的高温下也能保持其原有的硬度,同时钢铁质杆使铆杆具有一定的柔性,保证铆杆在旋压过程中不容易断裂。
为了使硬质合金牢固地固定在钢铁杆端头,在钢铁杆端头上设有一固定凹槽,硬质合金固定在凹槽内。这样,工作过程中施加在硬质合金上的径向力主要由钢铁杆凹槽壁来承受,避免了因硬质合金与钢铁杆端头结合力不足以承受铆杆工作过程中所产生的径向力而断裂。
本实用新型与已有技术相比,具有经久耐用、不易磨损的优点。
附图说明:
图1为本实用新型的结构示意图。
具体实施方式:
现结合附图和实施例对本实用新型作进一步详细描述:
如图所示,本实用新型主要是在钢铁杆1端头固接一硬质合金2而成,硬质合金2的端头设有球状凹坑3,在铁杆1端头上设有一固定凹槽4,硬质合金2固定在凹槽4内。
