Description
技术领域technical field
本发明属于特种加工技术领域，尤其涉及一种水平式电解电火花加工装置及方法。The invention belongs to the technical field of special processing, and in particular relates to a horizontal electrolysis electric discharge processing device and method.
背景技术Background technique
近年来，随着现代工业的高速发展，新型难加工材料的不断发现，微型化和精密化成为现在先进制造业发展的一个重要方向，对复杂微小零件的加工要求也越来越高。同时，随着微机电系统、微流体系统、航空航天等领域的蓬勃发展，耐热玻璃、陶瓷等具有耐高温、耐腐蚀、强度高等性能的非导电硬脆材料的应用也越来越广泛。然而，绝大部分硬脆材料，由于加工难度大，加工精度、表面质量和损伤层深度都将会对器件的性能产生影响，所以难以用传统的微细机械切削方法和常规的电火花加工技术对其加工。电解加工是一种基于阳极电化学溶解原理去除金属材料的制造技术，具有表面质量好、不受材料限制、工具无损耗等优点，加工过程中不存在变形层和残余应力等问题。In recent years, with the rapid development of modern industry and the continuous discovery of new difficult-to-machine materials, miniaturization and precision have become an important direction for the development of advanced manufacturing industries, and the processing requirements for complex and tiny parts are also getting higher and higher. At the same time, with the vigorous development of microelectromechanical systems, microfluidic systems, aerospace and other fields, heat-resistant glass, ceramics and other non-conductive hard and brittle materials with high temperature resistance, corrosion resistance, and high strength are more and more widely used. However, most of the hard and brittle materials are difficult to process, and the processing accuracy, surface quality and depth of the damaged layer will all have an impact on the performance of the device, so it is difficult to use traditional micro-machining methods and conventional EDM techniques. its processing. Electrolytic machining is a manufacturing technology based on the principle of anodic electrochemical dissolution to remove metal materials. It has the advantages of good surface quality, not limited by materials, and no loss of tools. There are no problems such as deformed layers and residual stress during processing.
电解电火花的加工过程大致为：阴极和阳极电解产生气泡，气泡经过聚集产生气膜，并包围在工件表面，气膜对电极产生绝缘作用，在工具电极和电解质溶液之间形成电势差，工具电极在气膜处产生电火花放电，工件材料就会在不断放电产生的热量作用下被蚀除。由上述加工过程可知，气膜是产生电火花效应的必要条件，气膜的厚度、形成速度、稳定性等都对加工过程有着非常重要的影响。但由于目前常采用的电解液的表面张力、粘度、密度等都比较小，因此，电解过程所产生的气泡会在浮力的作用下溢出电解液表面，使得只有小部分气泡可以参与气层的形成，从而使得气层的形成占据了比较长的时间，而这会大大缩短有效的放电时间，降低加工效率。The processing process of electrolytic spark is roughly as follows: the cathode and anode electrolysis generate bubbles, the bubbles gather to form a gas film, and surround the surface of the workpiece, the gas film insulates the electrode, and forms a potential difference between the tool electrode and the electrolyte solution, and the tool electrode Spark discharge is generated at the gas film, and the workpiece material will be eroded under the action of heat generated by continuous discharge. It can be seen from the above processing that the air film is a necessary condition for generating the spark effect, and the thickness, formation speed, and stability of the air film all have a very important influence on the processing process. However, due to the relatively small surface tension, viscosity, and density of the commonly used electrolyte, the bubbles generated in the electrolysis process will overflow the surface of the electrolyte under the action of buoyancy, so that only a small part of the bubbles can participate in the formation of the gas layer. , so that the formation of the gas layer takes a relatively long time, which will greatly shorten the effective discharge time and reduce the processing efficiency.
中国专利CN102528187A公开了一种倒置式电化学放电加工方法及装置，该申请提供一种特种加工领域的倒置电化学放电加工方法，具体是将工具电极安装在工件的下方，工具电极通过电极夹具固定在工作槽的底面并且浸没在电解质溶液中，工件与机床的进给装置相连接，通过工件的进给来实现加工过程中的进给运动。还提供相应的装置，通过改变工具电极和工件之间的相对位置，使加工过程中产生的加工屑在重力的作用下能够比较容易地排出，这就使得加工过程中加工孔内电解质的流动能力得到了增强，而且由于采用倒置布局，电解反应产生的气泡会富集在加工工件下方电极端部的周围，形成稳定的气膜，从而有效增加了电化学放电加工过程的稳定性并保证了加工深度。但是，该技术主要解决的是孔类或微槽类零件的微细电火花加工问题，更多的是实现了高效“点”式加工，运用在槽加工或缝加工过程中时，加工范围有限，存在明显地效率慢的问题。Chinese patent CN102528187A discloses an inverted electrochemical discharge machining method and device. This application provides an inverted electrochemical discharge machining method in the field of special processing. Specifically, the tool electrode is installed under the workpiece, and the tool electrode is fixed by the electrode fixture. On the bottom surface of the working tank and immersed in the electrolyte solution, the workpiece is connected with the feeding device of the machine tool, and the feeding motion during the machining process is realized by the feeding of the workpiece. Corresponding devices are also provided. By changing the relative position between the tool electrode and the workpiece, the machining debris generated during the machining process can be discharged relatively easily under the action of gravity, which makes the flow capacity of the electrolyte in the machining hole during the machining process It has been enhanced, and because of the inverted layout, the bubbles generated by the electrolytic reaction will be enriched around the end of the electrode under the workpiece to form a stable gas film, thereby effectively increasing the stability of the electrochemical discharge machining process and ensuring the machining depth. However, this technology mainly solves the problem of micro-EDM of holes or micro-groove parts, and realizes more efficient "point" processing. When it is used in groove processing or seam processing, the processing range is limited. There is an obvious problem of slow efficiency.

为满足线、面加工要求，工具电极3可为电极丝或者是柱形电极，柱形电极可选圆柱体状工具电极或非圆柱体状工具电极（包括矩形体状工具电极或其他形状的工具电极，具体形貌不做过多限制），当选择圆柱体状工具电极进行加工时，第一伺服电机71工作，带动圆柱体状工具电极3以0-2500 r/min的速度旋转加工，当选择的柱形电极为非圆柱体状电极时，工具电极3在加工过程中不旋转。In order to meet the requirements of line and surface processing, the tool electrode 3 can be an electrode wire or a cylindrical electrode, and the cylindrical electrode can be a cylindrical tool electrode or a non-cylindrical tool electrode (including a rectangular tool electrode or other shaped tools electrode, the specific shape is not too limited), when the cylindrical tool electrode is selected for processing, the first servo motor 71 works, driving the cylindrical tool electrode 3 to rotate at a speed of 0-2500 r/min for processing, when When the selected cylindrical electrode is a non-cylindrical electrode, the tool electrode 3 does not rotate during processing.

利用本实施例提供的装置进行水平式电解电火花放电加工过程时，由于采用水平加工方法，加工过程中产生的加工屑在重力的作用下能够比较容易地排出，对电蚀屑的顺利排出起到更积极作用，这就使得加工过程中电解质的流动能力得到了增强，减少了短路和非正常放电现象的发生；且由于采用水平布局，电解反应产生的气泡会富集在待加工工件下方电极的周围，增加了气膜的稳定性，从而有效增加了加工稳定性和加工深度；另外，水平布局能够弥补常规微细电火花放电加工采用单一纵向“点”加工方式的缺陷，可进行“线”或“面”的加工以及较厚非导电材料槽的加工，根据电极的选择不同，也可进行线切割的加工，增加放电加工深度，扩大加工范围，提高加工效率。When using the device provided in this embodiment to carry out the horizontal electrolytic EDM process, due to the adoption of the horizontal machining method, the machining chips generated during the machining process can be discharged relatively easily under the action of gravity, which plays a role in the smooth discharge of the electrolytic erosion chips. This enhances the flow capacity of the electrolyte during processing and reduces the occurrence of short circuits and abnormal discharges; and due to the horizontal layout, the bubbles generated by the electrolytic reaction will be concentrated in the electrodes under the workpiece to be processed The surrounding area increases the stability of the air film, thereby effectively increasing the processing stability and processing depth; in addition, the horizontal layout can make up for the defect of conventional micro-EDM using a single longitudinal "point" processing method, and can carry out "line" Or "surface" processing and processing of thicker non-conductive material grooves, depending on the selection of electrodes, wire-cut processing can also be performed to increase the depth of EDM, expand the processing range, and improve processing efficiency.
