Description

铰钳刃头
技术领域
本发明与五金工具有关,具体是指一种用来剪断钢筋的专用工具铰钳上装配的铰钳刃头。
背景技术
将中细度的钢筋截断一般采用一种名叫铰钳的五金工具人工施力操作来实现,它一般装置有两只长杆形的手柄,通过铰轴活动的连接着两块上下对称分布刃口正对的刃片,两刃片前后由两块长条状护板及上下分布的两个销轴活动的连接夹持组装成一体形成刃头,利用杠杆原理带动两刃片对钢筋共同产生向心方向的剪断压力来截断,但在实际的操作中,对于新使用的刃口较锋利的铰钳来说,上下刃口作剪断的运动时较锋利的上下刃口可以钳住钢筋不让其向外打滑脱离开刃口并顺利的将其截断,而当刃口稍钝,则这种操作就会变得不易:欲截断的钢筋会随着逐渐闭合的刃口(上下刃口间的夹角由大变小)向外滑动脱离开刃口,刃口的剪切力无法作用到钢筋上使得截断操作无法顺利完成,为此不得不需要另一人协作来稳住钢筋防止其打滑才能完成截断操作,这无疑会浪费人工降低工效,如能在刃头结构上加上让钢筋无法自动打滑外移的附加件使得截断操作一人即可很容易的完成则是其改进的一个方向。
发明内容
本发明的目的便是提供一种铰钳刃头的新的技术方案,它可以解决前述的问题。
本发明技术方案的内容如下:它包含上、下刃片、护板、销轴,所述销轴的外端都活动的连接一与刃片平行且伸向刃片开口端即左端的弧状卡片,卡片的右端向右略伸出护板右侧边,卡片以上下刃片的对称线为对称线也上下对称装置,上、下卡片的右半截间间隔有一定距离且在此处装置有一V形簧片将上、下卡片的右端分别上撑、下撑,一铆钉状的簧钉将簧片固定于上下对称线上;上、下卡片的左半截以对称线为中心紧靠且在此紧靠的边上都加工有相对应的齿牙且齿牙的左、右侧牙线与对称线间的夹角分别呈锐角、直角状。
本发明的有益效果是:铰钳对钢筋进行截断操作时钢筋不会再打滑且钢筋可以通过卡片齿牙左侧的锐角方便的撑开上下卡片进入刃片的上下刃口间并被上下卡片夹住,使得截断操作更容易工效更高。
附图说明:
图1是常用的铰钳刃头组件的正面视图。
图2是常用的铰钳刃头组件的左侧面视图。
图3是是常用刃头截断钢筋操作时钢筋外滑的情景演示。
图4是卡片装置就位后刃头的整体正面视图。
图5、图6是本设计刃头夹住钢筋过程的演示正视图。
各图中,1为上刃片,2为下刃片,3为护板,4为销轴,5为钢筋,6为卡片,7为簧钉,8为簧片。
具体实施方式:
下面结合附图对本设计作举例说明。
如图1、图2、图3所示,常见的传统使用的钢筋铰钳的刃片组件一般包含上刃片1、下刃片2、护板3、销轴4,刃片在作截断操作时常会出现如图3状的钢筋5外滑脱离开刃口的情况。为此,如图4、图5、图6所示,在销轴4的外端都活动的连接一与刃片平行且伸向刃片开口端即左端的弧状卡片6,卡片的右端则向右略伸出护板3的右侧边一段,卡片6以上、下刃片1、2的对称线为对称线也上下对称装置,上、下卡片的右半截间间隔有一定距离且在此空间处装置有一V形簧片8将上、下卡片的右端分别上撑、下撑,一铆钉状的簧钉7将簧片固定于护板3上的处于对称线上的部位,如图4所示;上、下卡片6的左半截以对称线为中心紧靠,同时在此紧靠的边上都加工有相对应的齿牙且齿牙的左、右侧牙线与对称线间的夹角分别呈锐角、直角状,藉此可以让欲剪断的钢筋5无需人为的撑开卡片再放进刃口内而是可以通过卡片的锐角特征方便的撑开上下卡片进入刃片的上下刃口间并被上下卡片夹住,使得截断操作更容易工效更高,如图5、图6所示。
