Pressing method of four-column hydraulic machine

Abstract

The invention discloses a pressing method of a four-column hydraulic machine, and relates to the technical field of hydraulic machines, in particular to the pressing method of the four-column hydraulic machine. The pressing method of the four-column hydraulic machine comprises a supporting base and a hydraulic mechanism, a main body frame is arranged above the supporting base, a machining base isarranged in the middle of the upper portion of the main body frame, and the hydraulic mechanism is arranged above the machining base; and the hydraulic mechanism comprises a hydraulic column, a fixingsleeve, a mounting panel, a light supplementing lamp, sliding sleeves, a guide column and a pressing panel, wherein the light supplementing lamp is arranged in front of the fixing sleeve, the mounting panel is arranged below the hydraulic column, and the sliding sleeves are arranged in the left end and the right end of the pressing panel. According to the pressing method of the four-column hydraulic machine, the system overall control does not contain a proportional servo valve or proportional pump link, the servo-driven hydraulic machine has the advantages of being capable of saving energy,low in noise, small in temperature rise, good in flexibility, high in efficiency, convenient to maintain and the like, and the servo-driven hydraulic machine can save electricity by 30%-70% compared with a traditional hydraulic machine according to different machining processes and production takts.

Description

technical field [0001] The invention relates to the technical field of hydraulic presses, in particular to a pressing method of a four-column hydraulic press. Background technique [0002] A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal’s principle to transfer energy to realize various processes. The hydraulic press is generally composed of three parts: the machine, the power system and the hydraulic control system. The hydraulic press is classified into valve hydraulic press, Liquid hydraulic press, engineering hydraulic press; a hydraulic press is a machine that uses hydrostatic pressure to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing processes and pressing forming processes, such as forging, stamping, cold extrusion, calibration Straight, bending, flanging, sheet drawing, powder metallurgy, press-fitting, etc. Its principle is to use Pascal's law to make use of liquid pr...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a pressing method of a four-column hydraulic press, which solves the problem of poor buffering performance of the hydraulic press proposed in the above-mentioned background technology during use, and the hydraulic bar is easy to damage the workbench and the workbench when it is in contact with the workbench. The base produces a large impact force, resulting in damage to the lower workbench, which cannot meet people's needs and other problems.
