摘要
针对轧钢机的只要特点,在分析其结构的基础上,进行设计。
主要设备直接使轧件产生塑性变形的设备称为主要设备,也称为主机列。它包括:工作机座(轧辊、轴承、轧辊调整装置、导卫装置及机架等),万向或梅花接轴,齿轮机座,减速器,主连轴节,主电机等。
辅助设备是指主机列以外的各种设备,它用于完成一系列辅助工序。辅助设备种类繁多,车间机械化程度越高,辅助设备所占整个车间机械设备总重比例也越大。
关键字:轧辊;工作机架;轴承
Abstract
Outside the abstract presses the question in view of the steam turbine
high school which the cylinder processes, in analyzes its unique feature in the foundation, should use the processing center processing, like this can increase the processing precision, the uniformity is good, moreover greatly enhanced the productivity, thus reduced the processing cost. Because the ordinary engine bed is controlled to the operation worker, therefore, uses on the ordinary engine bed is only a technological process card, the engine bed labor cutting specifications, the route,
Theorking procedure labor step and so on often all is operates the worker voluntarily to designate. The numerical control processing procedure is the numerical control engine bed instructional document. The processing center is controlled to the program directive, the processing entire process all is automatically enters according to the program directive for. Therefore, the numerical control proce
