Abstract

本发明公开了可检测螺栓搓丝过程中跳动的螺栓搓丝工艺。螺纹成型加工过程中，螺栓刚进入牙板时由于突然受到牙板的作用力或进料有倾斜时容易跳起。本发明的步骤：螺栓冷镦半成品在上料振动盘振动下由搓丝轨道进入动、静搓丝板的间隙进行搓丝；动、静搓丝板的入口端设有感应片，若螺栓冷镦半成品刚进入动、静搓丝板的间隙时发生跳起情况，螺栓头部会触碰到感应片；感应片将信号传给螺栓搓丝设备；螺栓搓丝设备自动停机，并发出异常警报；此时，需要取出报废的螺栓，重新调试并启动螺栓搓丝设备；若螺栓冷镦半成品未发生跳起情况，则螺栓杆柱面在动、静搓丝板相互搓动下形成配合螺纹。本发明可避免搓丝过程中螺栓跳起引起的螺牙长度不合格现象。

Description

可检测螺栓搓丝过程中跳动的螺栓搓丝工艺
技术领域
本发明属于车用紧固件技术领域，涉及车用螺栓，具体涉及一种可检测螺栓搓丝过程中跳动的螺栓搓丝工艺。
背景技术
螺纹的成型加工通过搓丝机以及牙板进行螺牙成型，在螺纹成型加工的过程中，螺栓刚进入牙板时由于突然受到牙板的作用力，或螺栓进料有倾斜时，都会致使螺栓容易跳起，导致螺纹长度太短，达不到要求。
发明内容
本发明的目的是为了解决搓丝过程中螺栓跳起引起的螺牙长度不合格的现象，提出一种可检测螺栓搓丝过程中跳动的螺栓搓丝工艺。
本发明的具体步骤如下：
步骤一、螺栓冷镦半成品放入上料振动盘。
步骤二、上料振动盘振动，螺栓冷镦半成品进入到搓丝轨道，并由搓丝轨道进入动、静搓丝板的间隙内。
步骤三、动、静搓丝板对螺栓冷镦半成品进行搓丝。静搓丝板固定不动，动搓丝板与静搓丝板相对设置且沿平行静搓丝板方向往复移动。在动、静搓丝板的入口端设有感应片，若螺栓冷镦半成品刚由搓丝轨道进入动、静搓丝板的间隙时发生跳起情况，螺栓头部会触碰到感应片；感应片将信号传给螺栓搓丝设备；螺栓搓丝设备自动停机，并由警报器发出异常警报；此时，需要取出报废的螺栓，重新调试并启动螺栓搓丝设备。若螺栓冷镦半成品未发生跳起情况，则螺栓杆柱面在动、静搓丝板相互搓动下形成配合螺纹。
步骤四、对搓丝后的螺栓进行热处理，所述的热处理为调质或渗碳。
步骤五、对热处理后的螺栓进行表面处理，所述的表面处理为表面镀锌、涂覆或磷化处理。
本发明具有的有益效果：
本发明可避免搓丝过程中螺栓跳起引起的螺牙长度不合格现象，保证螺栓成品的合格率。
具体实施方式
下面通过实施例对本发明做详细的说明。
可检测螺栓搓丝过程中跳动的螺栓搓丝工艺，具体步骤如下：
步骤一、螺栓冷镦半成品放入上料振动盘。
步骤二、上料振动盘振动，螺栓冷镦半成品进入到搓丝轨道，并由搓丝轨道进入动、静搓丝板的间隙内。
步骤三、动、静搓丝板对螺栓冷镦半成品进行搓丝。静搓丝板固定不动，动搓丝板与静搓丝板相对设置且沿平行静搓丝板方向往复移动。在动、静搓丝板的入口端设有感应片，若螺栓冷镦半成品刚由搓丝轨道进入动、静搓丝板的间隙时发生跳起情况，螺栓头部会触碰到感应片；感应片将信号传给螺栓搓丝设备；螺栓搓丝设备自动停机，并由警报器发出异常警报；此时，需要取出报废的螺栓，重新调试并启动螺栓搓丝设备。若螺栓冷镦半成品未发生跳起情况，则螺栓杆柱面在动、静搓丝板相互搓动下形成配合螺纹。
步骤四、对搓丝后的螺栓进行热处理，热处理为调质或渗碳，使螺栓的硬度值达到要求。
步骤五、对热处理后的螺栓进行表面处理，表面处理为表面镀锌、涂覆或磷化处理。
