摘  要

 
冲压机机架采用三梁四柱结构，上下各一个固定横梁，横梁用四个立柱支撑，一个活动梁（滑块）沿四个立柱移动，在活动梁（滑块）和一个上下梁之间有上下加热板和模具。被加工的物料放在上下模具之间冲压成型。为了增加产量，提高生产效率，主机采用双机组结构。
   四柱式机构为冲压机常见的结构形式之一，机身是典型的三梁四柱结构。主缸布置在上横梁中心。活动横梁与主缸活塞刚性连结并由主缸活塞驱动。由四柱导向完成压制和回程动作。控制箱安装在主机右前侧，各控制按钮和压力表，调压阀等，均布置在箱体面板上，因此工作者在控制箱前即可集中操纵和调整。上滑块行程限位装置则布置于机身右前侧。可以调整活动横梁上限，减速和下限位置。动力机构布置于主机右侧并由管路系统与主机连接起来。

 ABSTRACT

    Punch machine hosts a three-beam four-column structure, a fixed upper and lower beams, beams with four columns support an active beam (slider) moves along the four columns, beams in the activity (slider) and a between the upper and lower beam there are upper and lower heating plate and the mold. Material to be machined on the heat and pressure between the upper and lower mold forming. In order to increase production, improve production efficiency, host dual unit structure.
Four-column hydraulic press agency as one of the common structure, the body is a typical three-beam four-post structure. Master cylinder arranged in the beam center. Centers are arranged in a table top of the cylinder. Activities rigid beam link with the main cylinder piston driven by the master cylinder piston. Suppressed by the four-post and return to complete the action-oriented. Right front control box installed on the host side, the control buttons and pressure gauge, regulator, etc., are arranged in the cabinet panel, so workers can focus on the control box before the manipulation and adjustment. On the slide stroke limit device is arranged in the front right side of the fuselage. Activities can be adjusted ceiling beams, slow down and lower position. Arranged in the power sector by the pipeline system with the right host the host to connect.
