电磁阀里有密闭的腔,在不同位置开有通孔,每个孔连接不同的油管,腔中间是活塞,两面是两块电磁铁,哪面的磁铁线圈通电阀体就会被吸引到哪边,通过控制阀体的移动来开启或关闭不同的排油孔,而进油孔是常开的,液压油就会进入不同的排油管,然后通过油的压力来推动油缸的活塞,活塞又带动活塞杆,活塞杆带动机械装置。这样通过控制电磁铁的电流通断就控制了机械运动。
机床是指制造机器的机器,亦称工作母机或工具机,习惯上简称机床。一般分为金属切削机床、锻压机床和木工机床等。现代机械制造中加工机械零件的方法很多:除切削加工外,还有铸造、锻造、焊接、冲压、挤压等,但凡属精度要求较高和表面粗糙度要求较细的零件,一般都需在机床上用切削的方法进行终加工。机床在国民经济现代化的建设中起着重大作用。
车床是主要用车刀对旋转的工件进行车削加工的机床。在车床上还可用钻头、扩孔钻、铰刀、丝锥、板牙和滚花工具等进行相应的加工。车床主要用于加工轴、盘、套和其他具有回转表面的工件,是机械制造和修配工厂中使用广的一类机床。
锻压机床
锻压机床是金属和机械冷加工用的设备,他只改变金属的外形状。锻压机床包括卷板机,剪板机,冲床,压力机,液压机,油压机,折弯机等。
液压机是一种以液体为工作介质,根据帕斯卡原理制成的用于传递能量以实现各种工艺的机器。液压机一般由本机(主机)、动力系统及液压控制系统三部分组成。液压机分类有阀门液压机,液体液压机,工程液压机。
液压机(又名:油压机)液压机是一种利用液体静压力来加工金属、塑料、橡胶、木材、粉末等制品的机械。它常用于压制工艺和压制成形工艺,如:锻压、冲压、冷挤、校直、弯曲、翻边、薄板拉深、粉末冶金、压装等等。
它的原理是利用帕斯卡定律制成的利用液体压强传动的机械,种类很多。当然,用途也根据需要是多种多样的。如按传递压强的液体种类来分,有油压机和水压机两大类。
