Winding isostatic hydraulic press

Abstract

The invention discloses a winding isostatic hydraulic press, which comprises a machine seat, an oil supply device, a machine frame, a machine frame driving device, an upper end cover, an upper end cover driving device, a lower end cover, a cushion block and a cushion block driving device. A cylinder body is fixedly arranged on the machine seat, a workpiece to be processed is placed in the cylinder body, and the cylinder body is communicated with the oil supply device. The machine frame driving device can drive the machine frame to move relative to the machine seat, the upper end cover driving device comprises a first cylinder and a second cylinder which are located on two sides of the upper end cover respectively, the first cylinder and the second cylinder synchronously drive the upper end cover to move relative to the machine frame, and the upper end cover is placed on the upper portion of the cylinder body to seal the upper portion of the cylinder body. The lower end cover is arranged on the lower portion of the cylinder body, and a returning spring is arranged between the lower end cover and the machine seat. The cushion block driving device enables the cushion block to be placed on the upper portion of the upper end cover.

Description

technical field [0001] The invention relates to an isostatic hydraulic machine, in particular to a winding type isostatic hydraulic machine. Background technique [0002] The winding type isostatic hydraulic press in the prior art usually uses a cylinder to drive the upper end cover to move. According to the principle of leverage, this will cause an imbalance of pressure on the left and right sides of the upper end cover, resulting in insufficient sealing between the upper end cover and the cylinder body. tight. Contents of the invention [0003] In view of the above problems, the main purpose of the present invention is to provide a winding type isostatic hydraulic machine, which can place the upper end cover on the cylinder body more smoothly. [0004] In order to solve the above problems, the solution adopted by the present invention is a winding type isostatic hydraulic machine, which includes: a machine base; an oil supply device having an oil supply passage; The wo...
