摘 要
弹簧制作>卧式双轴搅拌机剪切机广泛地被运用在轧钢机械中，本文中涉及的是连铸机采用剪切机对各种型号的钢坯进行定尺处理。液压剪切机比火焰切割机运行成本低，而在同等的体积下，液压装置能比电气装置产生出更大的动力；同样在同等的功率下，液压装置的体积小、重量轻、结构紧凑。所以从各种角度看选择液压剪切机是比较合理的。液压剪切机是用液压作为主传动的剪切机，该剪切机采用平行刀片式的下切式。下切式剪切机的上下两个刀片都是运动的，但剪切扎件的动作是由下刀片来完成的。目前被广泛应用于初轧和钢坯车间。 剪切机液压系统主要由三部分组成。分别是下刀台系统、辊道小车驱动系统和上刀台抬升系统。其中下刀台剪切系统主要控制下刀片的进刀和快退；辊道小车驱动系统主要用于前进时保持剪切机与钢坯同速，剪切完成后快速返回；上刀台抬升系统用来移动上刀台。其中下刀台剪切缸单独采用变量泵驱动，而辊道下车油缸和上刀台抬升缸共用一个定量泵，其动作由换向阀实现。 关键词：剪切机 、 一周药盒>升降柱cncame辊道小车 、 油缸
Abstract
Shearing machine is widely used in steel rolling machines,this paper introduces the continuous casting machine by useing shearing machine to handle various types of steel billet. Hydraulic shearing machine has lower operating cost than flame cutting machines. However, in the same volume, the hydraulic device generates mush power than electrical equipment. In the same power, the hydraulic device small volume, light weight and compact structure. So from various perspectives, choosing hydraulic shearing machine is more reasonable. Hydraulic

穿戴式步态分析仪shearing machine is a kind of shearing machine that uses hydraulic pressure as the main drive. It chooses the down-cut sheet of parallel slice. The up-cut sheet and the down-cut sheet of down-cut shearing machine are movable, but the action of shearing the rolled piece is done by down-cut sheet. At present, it is widely used in the workshop of bloom and billet.
The hydraulic system of shearing machine mainly consists of three parts: the system of down-cut bed, the driving system of table roller vehicle and the system lifted by top-cut se
t. Its down-cut bed’s shearing system. Mainly controls advancement and retreat of the down-cut slice. The driving system of table roller vehicle is used to keep the shearing machine having the same speed with billet and resets quickly after finishing shearing. The lifting system of top-cut table can drift the top-cut bed. And the shear cylinder of down-cut bed is driven by variable pump independently, while the cylinder of table roller and lifting vat of top-cut bed are used a quantitative pump, and the operation is done by using reversing valve.
