Hydropress with bidirectional couple levelling function

Abstract

The invention relates to a hydropress with bidirectional couple levelling function, comprising an upper separator, four supports, lower separators, master cylinders and lateral cylinders, wherein a slider is connected with the master cylinders and the lateral cylinders. The hydropress is characterized in that levelling cylinders are fixedly installed on the upper and lower parts of each support; piston rods of the levelling cylinders are connected with the upper and lower ends of the four corners of the slider; levelling cylinders at the upper ends of the four corners of the slider form a torque group capable of applying couples with equal magnitude and opposite directions with levelling cylinders at the lower ends of the diagonals of the slider; and displacement sensors are also arranged at the four corners of the slider. The hydropress has the following advantages: the hydropress realizes levelling the press slider by utilizing the bidirectional couple levelling principle, thus not only shortening the levelling response time and improving the slider levelling precision and press production efficiency, but also avoiding loss of the main tonnage of the hydropress, substantially saving energy and lowering the production cost.

Description

technical field [0001] The invention belongs to the field of hydraulic press machinery, and in particular relates to a hydraulic press with a two-way force couple leveling function. Background technique [0002] With the development of the titanium industry, the specifications of forgings are getting larger and larger, and the tonnage of corresponding presses is also increasing. The tonnage of some aviation forgings for presses has exceeded 20,000 tons. Therefore, titanium, zirconium and titanium, zirconium alloys The forging precision of forgings is getting higher and higher. At present, the typical structure of the hydraulic press used to process special metal electrodes is a three-beam four-column type. The layout of the main oil cylinder and slider of the hydraulic machine is that four main oil cylinders are installed in the middle of the upper beam, and the slider is connected with the plunger of the main oil cylinder. Pillars are installed between the crossbeam, workb...

AI Technical Summary

Problems solved by technology

In addition, because the distance between the four leveling cylinders is small, that is, the leveling torque is small, not only the leveling response time is long, the leveling accuracy and production efficiency are low, but also it is easy to cause the loss of the main tonnage of the press and waste energy
