200噸液壓機畢業設計
摘要

本次畢業設計的主要任務為200T三梁四柱式液壓機的結構設計及控制系統設計。液壓機的應用較廣泛，在日常生活中到處可以見到，其基本工作原理為根據帕斯卡原理。以液體作為傳遞介質，達到實現能量的轉換的效果，從而實現各種鍛壓的成型工藝。這種液壓機適用于各種可塑性工件的壓制工藝，如沖壓、拉伸薄板、壓制、翻邊、彎曲等，也適用于砂輪成型、工件的校正、壓裝和各種冷擠金屬零件成型、塑膠制品及粉末制品的壓制成型工藝。液壓機是由主機和液壓控制系統、電氣控制系統組成。液壓機主機走成包括工作臺、上橫梁、導柱、滑塊、頂出缸、主缸、安裝地基等，動力機構包括泵、油箱、電機、電氣控制系統、各種液壓控制閥等。動力機構在電氣控制系統控制下，通過液壓系統，實現能量的轉換、傳遞和調節，完成各種工藝循環。

關鍵詞：四柱式液壓機，液壓系統，電氣系統，PLC控制

ABSTRACT
The graduation design task for 200T the structure design of three beam four-column type hydraulic press machine control system design. Hydraulic press application more widely, can be seen everywhere in our daily life, its basic working principle is according to the driving principle of the liquid to liquid as PASCAL transfer media, achieve the result of realization of energy conversion, so as to realize all kinds of forging press molding process. The hydraulic press suppression techniques are suitable for all kinds of plastic parts, such as stamping, stretching, pressing plate, flanging and bending etc., can also be applied to wheel molding, artifacts of calibration, pressure equipment and a variety of cold extrusion molding metal parts, plastic products and powder products of pressure molding process. Hydraulic press is controlled by the host and hydraulic system, electrical control system. Hydraulic press host go into workbench, beams, guide pin, slide block, ejection cylinder, master cylinder, such as installation of foundation, motivation mechanism including pumps, tanks, motor, electric control system, all kinds of hydraulic control valves, etc. Dynamic mechanism under control in the electric control system, through the hydraulic system, realization of energy conversion, transfer and adjustment, finish all kinds of process cycle.

Keywords: four column hydraulic machine, hydraulic system, electrical control system, PLC
