济南模具现在是应用非常去普遍的!但是模具加工的技术要求也是非常重要的,那么今天就由济南市宏捷模具有限公司带大家了解一下模具精密电火花加工的技术都需要哪些技巧?
  Jinan mold is now widely used! However, the technical requirements of mold processing are also very important. Today, Jinan Hongjie Mold Co., Ltd. will take you to know what skills are needed in the technology of mold precision EDM?
  1. 精密电火花加工的前提
  1. Premise of precision EDM
  对于高附加值模具0件的电火花加工,一般放电机床难-以胜任完成,选择高-精密电火花加工机床是前提。精密电火花加工机床在结构的力学性能、主轴和工作台的各几何精度方面应满-足高-精度要求。高-精度光栅尺的全闭环控制方式,能获得及高的自动定位精度。机床的脉冲电源性能决定放电加工的性能,要尺寸精、轮廓清的话就要求放电间隙很。谛〖湎都庸ぬ跫下能实现稳定加工,自动监控每个放电脉冲的状态,确-保不-良脉冲不产生破坏作用。高速抬刀技数能使加工废屑和焦油有-效地排出,获得稳定的放电间隙。
  For EDM of 0 pieces of high value-added mould, it is difficult to put the motor bed in order to be competent to complete, so the selection of high-precision EDM machine is the premise. The mechanical properties of the structure, the geometric accuracy of the spindle and the worktable of the precision EDM machine tool should meet the requirements of high precision. The full closed-loop control mode of high-precision grating ruler can obtain high automatic positioning accuracy. The performance of pulse power supply of machine tool determines the performance of EDM. If the size and contour of the machine tool are to be fine, the discharge gap is required to be very small. Under the condition of small gap machining, stable machining can be realized, and the state of each discharge pulse can be monitored automatically to ensure that the bad good pulse does not have destructive effect. High speed knife lifting technology can effectively discharge the processing waste and tar, and obtain a stable discharge gap.
  2. 精密电火花加工的工艺方法
  2. Process method of precision EDM
  精密电火花加工采用多电及加工的工艺方法。根据加工部位在粗、半精、精加工中放电间隙不同的特点采用几个相应尺寸缩放量的电及完成一个型腔的粗、半精、精加工。
  The precision EDM adopts the technology of multi electricity and machining. According to the different characteristics of the discharge gap in the rough, semi-fine and finish machining of the machining parts, several scaling quantities of corresponding dimensions are used to finish the rough, semi-fine and finish machining of a cavity.
  因摇动量。故蔷哂泻芨叩姆滦尉,且摇动加工使放电稳定,可获得侧面与底面均匀的表面粗糙度,被广-泛采用。精密加工中需要换用多个电及,只要保正重复的定位精度,就可以达到满意的工艺效-果。
  Because of the small rolling momentum, it still has a high profiling accuracy, and the rolling machining makes the discharge stable, which can obtain the surface roughness of the side and the bottom, which is widely used. In the precision machining, it is necessary to use more than one electromotor. As long as the positive and repeated positioning accuracy is maintained, satisfactory process efficiency can be achieved.

  3. 保正精密加工定位精度的方法
  3. Method to ensure the positioning accuracy of precision machining
  精密电火花加工为保正及高的重复定位精度,也不降-低加工效率,采用快-速装夹的定位系统,如GF加工方案3R快-速装夹夹具。使用这类夹具时,只要在配套前对精度作好了调试,在加工中重复定位精度可达±2μm,电及和工件都可以快-速换装,加工前使用分中基准球工具,利用数控电火花机床的自动分中功能,完成主轴夹头与工件中-心0点的定位。
  In order to ensure positive and high repetitive positioning accuracy, and to keep low machining efficiency, precise EDM adopts the positioning system of fast clamping, such as GF machining scheme 3R fast clamping. When using this kind of fixture, as long as the accuracy is adjusted before matching, the repeated positioning accuracy can be up to ± 2 μ m in the process of machining, and the electric and workpiece can be changed quickly. Before machining, use the reference ball tool of the center dividing, and use the automatic center dividing function of the CNC EDM machine tool to complete the positioning of the zero point of the main axis chuck and the workpiece center.
  4. 精密加工对电及的要求
  4. Requirements of precision machining on electricity and
  电及的材料在精密加工中是一个关键的问题。紫铜在电加工领域里是用得多的电及材料,能满-足较高-精度的加工要求,但在微细加工中,为了减少电及损耗,减少电及数量,提-高加工表面质量,实现高稳定的加工,应考虑选用价格较贵的铜钨合金电及材料。电及在用于电火花加工前应对尺寸、形状进行详细的投影测量,全-面检测合格后才用来加工。在实际生产加工中,由于电及不合格的问题造成的报废事例是很多的。因此精密加工中抓好电及的制造这一环节是重要的。
  Electric materials are a key problem in precision machining. Copper is widely used in the field of electrical processing and materials, which can meet the requirements of high-precision machining. However, in order to reduce electrical and loss, reduce electrical and quantity, improve machining surface quality, and achieve high and stable machining, we should consider the selection of expensive copper tungsten alloy electrical and materials. Before being used in EDM, the size and shape shall be measured in detail, and only after passing the full face test can it be used for machining. In the actual production and processing, there are many cases of scrap due to the problems of electricity and disqualification. Therefore, it is important to pay attention to the manufacturing of electricity and precision machining.
  5. 精密加工中电规准的控制
  5. Control of electric gauge in precision machining
  精密加工使用的高-档机床电规准的控制方法一般是智-能化控制的。加工中由计算机监测、判断电火花加工间隙的状态,在保持稳定电弧的范围内自动选择使加工效率达到高的加工条件。
  In general, the control method of high-grade machine tool electric gauge used in precision machining is intelligent energy control. In the process of machining, the gap state of EDM is monitored and judged by computer, and the machining condition of high machining efficiency is automatically selected within the range of keeping stable arc.
