第七十二章轴承与来信

劳动人民的智慧又让苏油大吃一惊,滚珠轴承的研发虽然尚未成功,但是程石两家工坊的人一合计,竟然将滚珠换成了短圆柱。

滚珠轴承,变成了滚子轴承!大大降低了技术难度不说,还增加了轴承的抗压强度!

滚子轴承折刀虽然用不上,但是已经完全满足了球磨机的要求!

接下来的事情,苏油亲自作图,让程石两家立刻将轴承投入使用当中。

程家向大型装备进军,开通水渠,开发出了可以利用水能的球磨机,日出观音土泥浆五百斤!

石家则还是人力驱动,设备较小,但是精度极高,轴承加上螺纹夹具,旁边加上一把刀片夹具,加上精准到厘级的量尺,一台原始的车床,出现在了石家铁坊的一间屋子里!

这可是加工柱形件和螺纹的神器。

看过复杂而精细的刀具手工打磨程序,苏油又给自己喜欢的徒弟设计了两件设备,砂轮机和砂带机。

砂轮机好理解,就是轴承带着一个圆形的砂轮旋转,用于打磨工件。

这玩意儿其实玉工早就在用了,叫飞陀。

但是有一个问题,砂轮的钢性会带动打磨的铁件跳动,只能用于粗磨。

而砂带机则是利用两个轮子,带动一条环形的皮带转动,带子是用喷枪喷上胶液,然后均匀洒上各种粗细程度的沙子制成。

一个轮子是可调的,可以在上好砂带后调节两个轮子之间的距离,将砂带绷紧。

转动轮子,轮子之间的砂带成水平运动,并且由于砂带本身的弹性,可以抵消使用砂轮时的那种跳动,贴合性更好,可以满足打磨平面的需要。

于是在打造好五柄羽纹花钢的剑胚之后,再磨出精致的剑条,简直就是轻而易举的事情。

石通对这小师父已经比对自己亲爹还孝顺了,这两件东西,直接关系到铁器的产量,这是量级跳跃式的增长,两台机器,足能抵上新开五个铁器坊!

这天苏轼和苏油就在铁坊,苏油指导石通,而苏轼在一边看热闹。

石通和苏轼也混熟了:“大郎这是怎么了,天天来看我们工坊的运作,读书考进士才是正理。”

苏轼挥着手不以为意地说道:“嵇康是大文豪,还不是一样亲自打铁,这是雅趣。”

石通不信:“大郎这话说得,欺哄我措大呢。”

苏油笑道:“这事情还真是有记载的,嵇康尝与向秀共锻于大树之下,钟会往造,嵇康不为之礼,而锻不缀。钟会良久乃去,康谓曰‘何所闻而来?何所见而去?’会曰‘闻所闻而来,见所见而去。’不用理会子瞻,我们继续聊四把火。”

“所谓的四把火,是整体热处理的四种基本工艺,分别是退火、正火、淬火、回火。”

“退火是将工件加热到适当温度,根据材料和工件尺寸采用不同的保温时间,然后进行缓慢冷却,目的是使金属内部组织达到或接**衡状态,获得良好的工艺性能和使用性能。”

“比如要增加铁片的韧性,延展性,弹性,便要用到这个工艺,其实你应该是熟悉的。”

石通说道:“对,退火后的铁片会变得很软。”

苏油点头:“第二种叫正火,是将工件加热到适宜的温度后在空气中冷却,少了退火的保温过程,得到的效果同退火也很相似,只是得到的铁中组织更细,还常用于改善材料的切削性能与弹性,这个对我们打造羽纹花钢很重要。”
