一、概要宇部兴产股份公司设计、制造和使用的2000吨双立柱下拉式锻造液压机,是高压油泵直接驱动的,用来锻造特殊钢和特殊超耐热合金钢。由于锻造温度范围狭,必须在短时间内将工件锻造到所需尺寸。而且,由于变形阻力大,对油压装置的要求是相当严格的;精锻时,锻造液压机的工作周期必须是90次/分。由于对现代锻造液压机要求制品精度高、锻造速度快、操作方便等等,故必须采用数字控制的厚度控制装置,以及压机和操纵机联动的一
I. Outline The 2,000 ton twin column pull-down forging hydraulic press designed, manufactured and used by UBE Co., Ltd. is a direct drive of high-pressure oil pump for forging special steel and special superalloy. Due to the forging temperature range is narrow, the workpiece must be forged to the required size in a short time. Moreover, due to large deformation resistance, the hydraulic device requirements are quite strict; precision forging, forging hydraulic press working cycle must be 90 beats / min. Due to the requirements of modern high forging hydraulic products, forging speed, easy to operate, etc., it must be used to control the thickness of the digital control device, and press and control of the linkage of a
