摘要本次设计的为可用于可塑性材料压制工艺的锻压机，例如冲压、弯曲、翻边、薄板拉伸等工艺，同样适用于校正、压装、砂轮成形、冷挤金属零件成形、塑料制品及粉末制品的压制成形工艺等。锻压机液压系统所使用的控制方式为为集中按钮控制，可以实现手动调整和半自动循环两种操作规范。
本次设计的锻压机的工作压力、快速下行和减速下行的行程范围，可根据工作需要进行调节。它能够实现带顶出和不带顶出两种工艺方式，而且每种工艺方式中又有定压成形和定程成形两种工艺动作可供选择。主缸在压制后具有保压、延时及回程等功能，而顶出时则有顶出延时、退回等动作。保压延时和顶出延时的时间均可由时间继电器调定。本次设计的锻压机具有独立的动力系统，采用PLC控制，便于调整及文修。液压装置系板式阀集成，结构紧凑，动作可靠。27897

ABSTRACT
This machine is suitable for the suppression of plastic materials, processes, such as stamping, bending, flange, sheet steel and other technology can also be used to correct, press-fit, wheel forming, cold extrusion forming of metal parts, plastic products and powder products forming process .Button on the machine for centralized control, can be manually adjusted to achieve the two practices and semi-automatic cycle
Working pressure of the machine, fast, and slow down the trip down the scope of work to be done according to regulation. It can achieve with the top out and without the top two kinds of process methods, the way each technology have given constant pressure forming and shaping of two-way process moves to choose from. After the suppression of the master cylinder has a packing, delay, and return other functions, and top out top out when there are delays, return and other activities. Paul rolled the top of the time and the time delay relay can be adjusted by the time set. This machine has an independent power system, easy adjustment and maintenance. Plate valve hydraulics system integration, compact and reliable action.
Keywords: forging machine, centralized control, Design of machinary, Hydraulic System, Programmable Logic Controller
