Description

一种基于前混合磨料射流切割曲面厚度不均匀板材的装置 技术领域
本发明涉及磨料水射流机械设备设计技术领域，尤其涉及一种基于前混合磨料射流切割曲面厚度不均匀板材的装置。
背景技术
水射流是由喷嘴流出形成的不同形状的高速水流束，射流的流速取决于喷嘴出口截面前后的压力降。水射流是能量转变与应用的最简单的一种形式。通常，动力驱动泵通过对水完成一个吸、排过程，将一定量的水泵送到高压管路，使其以一定能量到达喷嘴。而喷嘴的孔径要求比高压管路直径小得多，因此到达喷嘴的这一一定量的水要想流出喷嘴孔，必须加速。这样，经过喷嘴孔加速凝聚的水就形成了射流。
然而，现有的前混合磨料射流切割设备虽然实现曲面厚度不均匀板材工件的切割加工功能，但存在加工精度低，射流能量浪费严重等问题，尤其前混合磨料射流设备因受磨料罐体积的限制，无法提供长时间持续作业，射流能量的浪费进一步缩短了切割作业时间。有些前混合磨料射流切割设备无法根据板材工件的弯曲率及厚度来实时调节喷枪的距离工件的靶距和移动速度，无法保证曲面厚度不均匀板材工件的切割质量，严重影响切割效率和工件加工质量，有些前混合磨料射流切割设备无法实现并联工作伺服控制同步运动，难以实现精确调节喷枪的射流参数功能，还有的前混合磨料射流切割设备难以实现自动设置射流切割参数功能，无法精确保证射流切割靶距参数，不能满足实际情况的需求。

所述喷枪的上端通过高压胶管连接有混合腔，所述混合腔的上端安装有磨料罐，所述混合腔的下端安装有便携推车，所述磨料罐还安装在便携推车上，所述混合腔的右端通过高压胶管连接有高压泵站。
现场使用时，首先，操作人员将曲面厚度不均匀板材工件固定在工件台上端的靶物架上，调节智能检测装置的位置使上检测器下端的球形头与下检测器上端的球形头位于曲面厚度不均匀板材工件的两侧，再调节起始喷头与曲面厚度不均匀板材工件位置，确保喷头底部与曲面厚度不均匀板材工件上侧面的距离处于合适切割的靶距范围内，设立曲面厚度不均匀板材工件起点位置后，根据数控面板上的走刀线路依次通过控制器将行走参数依次传输到辐射均布孔内的应力测试传感器上，辐射均布孔内的应力测试传感器根据路线自动分配依次激活辐射均布孔内对应的应力测试传感器。
其次，操作人员将混合腔移动到实验室非工作区内，再混合腔固定，将水管接入端安装 在高压泵站的水箱上，通过高压胶管将高压泵站输出端与混合腔的输入端相连接，再通过高压胶管将混合腔的输出端与喷枪的输入端相连接，启动高压泵站使高压水进入磨料罐内并在混合腔混合腔内与磨料混合，磨料混合液经高压胶管和喷枪从喷头中喷出，使用过后的磨料混合液从切穿的缝隙经通孔和C形同步架的下侧壁上的长腰形孔流入工件台内。
再次，启动控制器，在走刀过程中，被激活的应力测试传感器根据实际走刀的位置，来调节切割射流参数，根据反馈的切割射流参数进行切割作业，直至完成曲面厚度不均匀板材工件全部走刀过程并完成切割作业。具体是：曲面厚度不均匀板材工件两侧弯曲率和厚度检测的参数通过导柱和弹簧，并将位移参数经应力测试传感器转换为力参数，应力测试传感器通过数据线将参数传输给控制器，控制器通过数据线启动步进电机，再步进电机的驱动下，齿轮带动竖直齿条使沿着喷枪孔内进行上下移动并调节喷头与曲面厚度不均匀板材工件的靶距，与此同时，二维机床台根据控制器内参数调节C形同步架的位置，进行切割作业。
最后，操作人员依次关闭控制器和磨料罐下端的磨料阀门，待喷枪内全部输出的为清水后，降低高压泵站的输出流量，直至关闭高压泵站，根据下次作业时间，合理清理磨料罐内的磨料，做好设备定期维护，等待下次进行切割作业工作。
与现有的技术相比，本发明的有益效果是：本发明能实现曲面厚度不均匀板材工件的切割加工功能，根据板材工件的弯曲程度及厚度来调节喷枪的距离工件的靶距和移动速度，确保曲面厚度不均匀板材工件的切割质量，大大提高切割效率，减少射流能量剩余，通过设置上环形同步环形传动链组和下环形同步环形传动链组和中心动力电机能保证上检测器和下检测器同步运动，并将上检测器和下检测器内应力测试传感器传导的力参数经控制器实时反馈给步进电机，实现精确调节喷枪的射流参数功能，通过设置辐射均布孔能测量多方向曲面厚度不均匀板材工件的弯曲率和厚度参数，并根据喷枪位置走向将参数反馈给控制器，实现自动设置射流切割参数功能，通过设置弹簧和导柱能将位移参数转化为力学参数并反馈给控制器，通过设置移动轮、移动轮槽、喷枪、竖直齿条和齿轮能实现喷枪在喷枪孔内移动功能，精确保证射流切割靶距参数，且结构简单，操作方便，经济实用。
