摘要
剪板機是機械生產(chǎn)中關(guān)鍵的輔助設(shè)備之一，運用電液結(jié)合對其進行自動化控制實現(xiàn)了剪板機的高效率、低噪聲、操作簡單、維護方便等諸多優(yōu)點。液壓技術(shù)作為實現(xiàn)現(xiàn)代傳動與控制的關(guān)鍵基礎(chǔ)技術(shù)之一，已成為工業(yè)機械、工程建設(shè)機械及國防尖端產(chǎn)品等不可缺少的基礎(chǔ)，是它們向自動化、高精度、高效率、高速度方向發(fā)展的關(guān)鍵技術(shù)。PLC是近幾年發(fā)展起來的一種新型工業(yè)控制器,由于它把計算機的編程靈活、功能齊全、應(yīng)用面廣泛等優(yōu)點與控制器系統(tǒng)的控制簡單、使用方便、抗干擾能力強、價格便宜等優(yōu)點結(jié)合起來，而其本身又具有體積小、重量輕、能耗低等特點，在工業(yè)過程控制中的應(yīng)用越來越廣泛。加之PLC以其在硬件設(shè)計中采用了屏蔽、濾波、光電隔離等技術(shù)，在軟件設(shè)計中采用了故障檢測、信息保護與恢復等措施，進一步提高了PLC的可靠性。
本課題中我主要進行液壓控制系統(tǒng)和泵站設(shè)計、PLC控制系統(tǒng)設(shè)計，該部分的完成是為了實現(xiàn)剪板機的自動化加工，減少勞動強度，提高加工效率。本文詳細介紹了設(shè)計的整個過程。

Abstract
The shearing machine is one of the most important accessory machinery in manufacturing. Controlled by electric and hydraulic make the shearing machine has high efficiency,low noise,simple operating and service freely. The hydraulic technology as one of the essential foundation technologies of the realization modern transmission and controlling, has become the essential foundation of the industry machinery, the engineering construction machinery and the national defense state-of-the-art product and so on, It is their essential technology to the automation,high accuracy,high efficiency and high speed . PLC is the controller of a kind of infant industry developed in recent years. Because the programming of a pair of computer of its is flexible , and controller control of system simple easy to use, anti-interference ability strong, price getting cheap advantage combined together, and it has characteristics such as small , light , power consumptive provinces ,etc, the application in the industrial process is controlled is more and more extensive. In addition PLC adopt , shield , strain wave , photoelectricity person who isolate technology in hardware design with their, have adopted measures such as detection of trouble , information protection and resuming ,etc. in software design, have further improved the dependability of PLC.
I mainly solve the shearing machine’s hydraulic system design,its pumping station design and the take-up parts’ PLC control in this topic, in order to realizes the machinery automatic processing, reduce worker's labor intensity, and enhance the mechanical efficiency.
Key words: Hydraulic system; Integrated hydraulic system; Pumping station; Programmable logic controller ; Full-automatic board cutting machine
