Four-column hydraulic press energy-saving control system and method thereof

Abstract

The invention relates to a four-column hydraulic press energy-saving control system and a method thereof. The system comprises a hydraulic upper body and a carrying receiving mechanism; the end side of the middle of the hydraulic upper body is provided with an upper lifting ring, the side end of the hydraulic upper body is provided with an alarm, the bottom end of the hydraulic upper body is fixedly provided with a hydraulic lower body, the side wall of the hydraulic lower body is provided with a through channel, and the middle of the hydraulic lower body is provided with a through groove; thecarrying receiving mechanism is arranged on the side end of the through channel; and the alarm is electrically connected with a first-stage gravity early warning unit, a second-stage gravity early warning unit, a third-stage gravity early warning unit, a first-stage hydraulic early warning unit, a second-stage hydraulic early warning unit and a third-stage hydraulic early warning unit. The four-column hydraulic press energy-saving control system and the method thereof have the beneficial effects that by using cooling fins, the side end of a box can be subjected to heat dissipation treatment conveniently, the service life of the box is prolonged, and a better use environment for the box can be achieved.

Description

Technical field [0001] The invention relates to the technical field of four-column hydraulic presses, in particular to an energy-saving control system and method for four-column hydraulic presses. Background technique [0002] The four-column hydraulic press is a mechanical equipment that uses the static pressure of the hydraulic oil delivered by the oil pump to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing processes and press forming processes, such as: forging, stamping, cold extrusion, straightening, bending, flanging, sheet deep drawing, powder metallurgy, pressing and so on. Its principle is to use Pascal's law to make use of hydraulic pressure transmission machinery, there are many types. Of course, the uses are also diverse according to needs. For example, according to the type of liquid that transmits pressure, there are two categories: hydraulic and hydraulic. [0003] The existing four-column hydraulic press is not equipp...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an energy-saving control system and method for a four-column hydraulic machine, so as to solve the problem that the control components of the existing four-column hydraulic machine proposed in the above background technology are not equipped with a good end movable structure. There are situations such as not convenient enough to use and not convenient to adjust, and because the design of the control system of the four-column hydraulic press is not reasonable enough, so that the four-column hydraulic press cannot be well regulated and used, and there is a situation of extremely poor practical performance.
