这样的数据里,最抢眼的就是适应线径从0.03到0.3mm。目前我问到的厂子里,最好的国产机器能加工的水品大约是0.2mm。受线径制约,很多需要细小位置的弹簧就因此很难被国内的厂商制造出来。比如心脏搭桥用的一种弹簧。

' ^7 Y& z' J/ A0 ^我问了些模具经销商,似乎加工机械的瓶颈主要还是在模具上。如果要用的话,0.2以下国内基本没希望,0.2以下台湾的还可以。日本的最好可以到上面的0.03mm。就是下面这三样东西:* }/ X& u# z( L, U9 y0 `

线板,图上是前线板,上面的凹槽也是和线径配合。 N5 T9 ]/ X0 l, c

这三样会在弹簧机上形成一个容纳钢丝的结构。如果凹槽与丝线直径配合的不好,就会影响弹簧的尺寸精度。凹槽小了过不去,卡线。凹槽大了,弹簧的尺寸会发生跳动,严重的会堵线。. P, E& `1 w$ X+ D+ D

对于论坛的能手来说,小尺寸的凹槽在制造的时候,究竟有哪些难度制约了这样的模具的制造?
