为了简化淬火压床的设计,便于制造、安装、操纵和维修,我们对国内外的淬火压床进行了分析对比。如 K-232型气动淬火压床结构简单,上压具中的内外压环压力分配件是由一组十二块摆动块组成的小杠杆,易于制造,压床刚度大。格利森529型压床自动化程度高,它的强制淬火时间可掌握到最短,有效地提高机床利用率。SP-3型压床结构简单,但液压油缸部分复杂,用三个套在一起的缸筒分别传递压力于内、外环和扩张器,磨削这些配合使用的缸筒要求很高技术。
In order to simplify the design of quench press, easy to manufacture, installation, operation and maintenance, we have analyzed and compared the quench press at home and abroad. Such as K-232-type pneumatic quenching simple structure, the pressure on the inside and outside the pressure ring pressure distribution member is composed of a group of twelve small swing lever consisting of small lever, easy to manufacture, the press stiffness. Gleason 529 high degree of automation of the press, it forced the quenching time can be mastered the shortest, effectively improve machine utilization. The SP-3 press has a simple structure, but the hydraulic cylinder is partially complicated. Cylinders with three sleeves are used to transmit pressure to the inner ring, the outer ring and the dilator, respectively. Grinding these cooperating cylinders requires high technology.
