Hydraulic system of hydraulic machine with power regulation function

Abstract

The invention discloses a hydraulic system of a hydraulic machine with a power adjusting function. The hydraulic system comprises a base, supporting legs, a fixed seat, a power adjusting mechanism, supporting columns, a top seat, a hydraulic cylinder, a hydraulic pipe and a hydraulic system. According to the hydraulic system, through the arrangement of the power adjusting mechanism, when in use, if a thicker workpiece is encountered, a driving oil cylinder drives the hydraulic seat to contract into a square block, so that the pressing stroke of the hydraulic cylinder is increased, and the pressing precision of the workpiece is guaranteed; through the arrangement of cushion blocks and clamping grooves, the multiple clamping grooves are formed in the two sides of the hydraulic seat from top to bottom, after the position of the hydraulic seat is adjusted, the cushion blocks are clamped in the clamping grooves, the cushion blocks bear the punching force of the hydraulic cylinder on the hydraulic seat, and the driving oil cylinder is prevented from being exploded or damaged; and the thickness of the cushion blocks is less than that of the clamping grooves, the structure is simple, clamping is convenient, and the labor intensity of workers is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of testing hydraulic presses, in particular to a hydraulic system of a hydraulic press with power regulation. Background technique [0002] Hydraulic press (also known as: hydraulic press) 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 process and pressing forming process, such as: forging, stamping, cold extrusion, straightening, bending, flanging, sheet drawing, powder metallurgy, press fitting and so on. [0003] The stroke of the existing hydraulic press is fixed when pressing. If the thickness of the workpiece to be pressed is large, the pressing stroke of the hydraulic press will be shortened, so that the pressing accuracy of the workpiece cannot meet the requirements. If the workpiece to be pressed is thin, an additional hydraulic press is required. The pressing stroke may not be able to pres...

Problems solved by technology

[0005] The object of the present invention is to provide a hydraulic system with a power-regulated hydraulic press to solve the problem that the stroke of the existing hydraulic press proposed in the background art is constant during pressing. If the thickness of the workpiece to be pressed is relatively large, the hydraulic press The pressing stroke of the hydraulic press is shortened, so that the pressing accuracy of the workpiece cannot meet the requirements. If the workpiece to be pressed is thin, the pressing stroke of the hydraulic press is increased, and the workpiece may not be pressed. For this reason, the staff also need to install a heightening block, which is very difficult to use. Inconvenient question
