The utility model provides an impact needle and a needle sleeve assembly for non-explosive charge, including a strike needle and a strike needle sleeve; the strike needle is arranged in the strike needle sleeve; the main improvement is that the front section of the strike needle consists of a strike needle cone, a cylinder section and a cone section in turn; and the strike needle cone is located at the front end of the strike needle sleeve; The diameter of the circle on the cone table is the same as the inner diameter of the hole in the plastic shell charge chamber of the nail-shooting component, and the diameter of the circle at the bottom of the cone table is larger than that of the plastic shell charge chamber of the nail-shooting component. Furthermore, the length of the needle cone is 1/10 to 1/5 of the length of the column. The utility model has the advantages that: 1) when the nail-shooting component of the non-explosive charge is fired, the nail-shooting component of the non-explosive charge is advantageous to fire transmission and full combustion. 2) When the upper chamber of the nail-shooting assembly is ready to be fired, the plastic shell of the nail-shooting assembly can produce certain deformation and close to the chamber, which is beneficial to the adherence to prevent gas leakage.
【技术实现步骤摘要】
无击发药装药击针及击针套组件
本技术涉及钉塑一体或分体射钉组件的击发机构,尤其是一种无击发药装药击针及击针套组件。
技术介绍
通常直射式(无活塞杆)射钉器击针1和击针套2如图1所示;击针1切入射钉组件3药柱部位是圆锥形,这种形状利于延长击针1使用寿命,其特点是随着击针1切入药柱,击针锥部对药柱产生的挤压和摩擦是逐步递减的;也就是说击发过程药柱的着火点是靠近射钉组件3的药室顶部,这对有击发药装药而言是极其合理的,因为击发药就装在射钉组件3药室顶部附近,但对无击发药装药而言就十分不利。一是不利于传火,导致燃烧不完全,影响威力;二是不利于贴壁(射钉组件3的塑壳与弹膛间),易泄露气压,导致威力下降,噪声增加。
技术实现思路
针对现有技术中存在的不足,本技术提供一种无击发药装药击针及击针套组件,对于无击发药装药射钉组件,药柱的着火点靠近药柱底部,这种着火方式利于传火,利于贴壁;在射钉组件上膛待击发时,射钉组件塑壳能够产生一定的形变紧贴弹膛,利于贴壁防止气体泄漏。本技术采用的技术方案是:一种无击发药装药击针及击针套组件,包括击针和击针套;所述击针设于击针套内;其主要改进之处在于,击针前段依次包括击针锥台、圆柱段和锥形段;其中击针锥台位于击针的前端部;击针套端部设有一个锥台,锥台上圆直径与射钉组件塑壳装药室孔内径相当,锥台底圆直径大于射钉组件塑壳装药室孔内径。进一步地,击针锥台的长度为圆柱段长度的1/10~1/5。本技术的优点在于:1)对于无击发药装药射钉组件击发时利于传火,燃烧充分。2)在射钉组件上膛待击发时,射钉组件塑壳能够产生一定的形变紧贴弹膛,利于贴壁防止气体泄漏。 ...
