1 引言
一般把单向送丝速度低于0.2m/s的电火花线切割加工方法称为慢走丝线切割加工.慢走丝线切割具有切割尺寸精度高、表面质量好的特点,能保证好的表面粗糙度、行位精度、基本尺寸精度等.慢走丝线切割的电极丝传送为单向输送,一次性使用,所以不存在电极丝变细的情况.由于慢走丝线切割的走丝速度较慢,电极丝的抖动也较小,能适合大锥度的切割加工.鉴于慢走丝线切割的诸多加工优点,现主要介绍如何采用慢走丝线切割加工层倍增器中最具代表性的大锥度异形孔.
2 加工难点分析
层倍增器是由6个不同板类零件装配而成,材料是S136,经过调质处理后硬度达到35HRC.现选其中最具代表性的一块板为例进行说明.加工难度分析如下：
（1）一般慢走丝线切割加工锥度在0~30°,而此次加工的异形孔锥度为41°,属于特殊的加工类型,零件结构如图1所示.
（2）上、下面4个孔前后异形,一侧是8㎜×6㎜的矩形孔,另一侧是6㎜×8㎜的矩形孔,需要找到它们的共同基准进行加工,可采用“四边分中”的方法选取工件中心作为加工基准.
（3）由于层倍增器各板间有连续塑料熔体流过,前一块板与后一块板的孔需要有较高位置精度来防止漏料,对孔的位置精度及表面质量要求较高,尤其在进行大锥度线切割加工中尤为明显.
（4）由于加工41°的大锥度异形孔需要打特殊的穿丝孔,一般打孔机只能加工直穿丝孔,需要做一个特殊的专用工装.
（5）用正常的加工方法加工此异形孔残料根本无法取出,所以需要编2个程序.用特殊的2次加工方法来完成.
（6）在试加工过程中,由于41°的大锥度使上下导丝嘴错开,切屑液无法冲洗加工部位,极易断丝,这在加工孔的拐角处尤为明显,需要结合机床本身的一些工艺参数和实际加工情况进行工艺参数修改.

1 introduction Generally delivers the silk speed to be lower than one way 0.2m/s the electrical fire colored thread cutting processing method to be called walks slowly the silk thread cutting processing. Walks silk thread cutting to have the cut lengths precision slowly to be high, the surface quality good characteristic, can guarantee the good surface roughness, the good position precision, the basic size precision and so on .Walks silk thread cutting the electrode silk transmission is the unidirectional transportation slowly, disposable use, therefore does not have the electrode silk thinning the situation. Because walks silk thread cutting to walk the silk speed slowly to be slow, the electrode silk's vibration is also small, can suit the big taper the cutting processing. In view of the fact that walks silk thread cutting slowly many processing merit, presently mainly introduces how to use walks in slowly the silk thread cutting processing level multiplier the most representative big taper abnormity hole.
2 processing difficulties analyze The level multiplier is becomes by 6 different planking component assembly, the material is S136, after undergoing the quenching and retempering treatment, degree of hardness achieves 35HRC. Presently elects is most representative a board to carry on the explanation for the example. The processing difficulty analysis is as follows:
(1) Generally walks the silk thread cutting processing taper slowly in 0~30°, but this processing's heteromorphous morse taper for 41°, belongs to the special processing type, components structure as shown in Figure 1.
(2) On, around the following 4 holes the abnormity, one side is 8㎜×6㎜ the rectangular hole, another one side is 6㎜×8㎜ the rectangular hole, needed to find their common datum to carry on the processing, might use “in four side minutes” the method selection workpiece center took the processing datum.
3) Because between level multiplier various boards has the continual plastic melt to wind through, the preceding board needs to have the high position precision with the latter board's hole to prevent to leak the material, is high to the hole position precision and the surface quality request, especially in carries on the big taper line to cut in the processing to be especially obvious.
(4) Because processes 41° the big taper abnormity hole needs to hit specially puts on the silk hole, generally the punching machine can only process puts on the silk hole straight, needs to make special special-purpose work clothes.
(5) Processes this heteromorphous hole remnant with the normal processing method to be unable to take out radically, therefore needs to arrange 2 procedures. Completes with the special 2 processing method.
(6) In tries in the processing process, because 41° the big taper causes to lead the silk mouth to stagger up and down, the scrap fluid is unable to flush the processing spot, Yi Duansi, this especially is extremely obvious in the processing hole's corner, needs to unify engine bed's some technological parameter and the actual processing situation makes the technological parameter revision.
