Description

水射流切割机 技术领域
本发明涉及一种切割机，尤其是一种水射流切割机。
背景技术
自水射流切割机出现之后，人类在一些高难度加工领域取得了长足进步，节省了大量人工劳力，并提高了切割加工水平。目前所生产的水射流切割机采用的技术有如下几点特点：Y轴横梁的铝材薄，缺点为易变形；Y轴横梁材料选用普通的铝型材，缺点为容易弯曲；选用圆导轨进行传动，缺点为直线度低；送沙装置为不可进行量控，缺点为浪费大，加大生产成本。
发明内容
本发明旨在针对目前市场上生产的水射流切割机所存在的诸多不足之处，对水射流切割机进行了优化、创新，意在使水射流切割机的性能更加稳定、提高生产效率、降低设备出现问题的概率、减少维修成本、加工成本节省人工。
具体地，根据本发明的水射流切割机包括Y轴部分、Z轴固定座部分、Z轴部分、切割平台、镀锌条、按钮箱、沙箱、磨料送料装置和切割头，沙箱和磨料送料装置共同组成送料系统，沙箱由上下两个料斗组成，两者通过装有密封圈的法兰连接在一起，上料斗作为储料罐可装大量磨料，可通过感应器测量磨料存量，下料斗内有一个微型气缸，通过气缸帽上下活动关闭或打开上下料斗连通。
优选地，磨料送料装置包括储沙罐、送料室和波轮，当磨料掉入下料斗后，下料斗内的压缩空气连同磨料通过软管一起注入位于切割头上方的磨料送料装置的储沙罐内，当开始切割时储沙罐内的沙子因为重力掉入送料器下方送料室内的波轮上，此时送料室内的步进电机转动波轮，根据所需沙量控制旋转速度将沙子送入与切割头连接的沙管内，在高压水的虹吸作用下沙子进入切割头。
优选地，Y轴横梁采用航空铝材进行加工，且铝材厚度加厚。
优选地，选用直线导轨进行传动。
本发明采用超厚的Y轴横梁，大大降低了横梁的变形量，采用航空铝材进行加工的横梁，不易弯曲，即增加了横梁的稳定性，又节约了因横梁弯曲维修的成本。选用直线导轨进行传动，提高了设备的直线度，保证了设备的精度。带有量控装置的送砂系统，杜绝了生产过程中砂石的浪费，节约了生产的成本。
