Abstract

The invention relates to a hydraulic machine for rapid water squeezing and shaping. The hydraulic machine comprises a frame, sliding blocks, a plurality of oil cylinders, a hydraulic control system, an oil supply pipeline and an electric appliance control system, wherein the sliding blocks are mounted in the frame in parallel in a guiding manner; the oil cylinders are evenly distributed on the frame below the sliding blocks at intervals; the oil cylinders are connected with the hydraulic control system respectively through the oil supply pipeline; and the electric appliance control system controls each action of the hydraulic control system according to a predetermined command. The hydraulic machine is characterized in that the rapid raising, the pressurized water squeezing, the pressure-maintaining shaping, the low-speed decompressing and the rapid descending of the sliding blocks are carried out by utilizing a pressurization control return circuit and a decompression control return circuit respectively, wherein the pressurization control return circuit controls the rapid raising, the pressurized water squeezing, the pressure-maintaining shaping of the sliding blocks; and the decompression control return circuit controls the low-speed decompressing and the rapid descending of the sliding blocks. The hydraulic machine has the advantages of low cost, simple structure, convenience in repair, low operation cost, high working efficiency and excellent cost performance, thereby overcoming the defects of high-grade and low-grade water squeezing and shaping equipment.

Description

technical field

[0001] The invention belongs to the field of hydraulic pressure, and relates to a hydraulic machine, in particular to a hydraulic machine for quickly squeezing water and setting the shape. Background technique

[0002] Squeezing and setting is one of the necessary processes for dehydration and setting in the process of prefabricated paper fiber composite board, soaking fiber materials, leather making, etc. The main function of this process is to squeeze the prefabricated paper fiber composite board, soak Squeeze out the excess water in fiber materials, leather and other materials, and press them into a certain shape, such as pressing into plates, etc., to meet the operating requirements of the next process. Therefore, the water squeezing and setting equipment requires high pressure and fast speed. When the pressure is released, the plate will not burst and the machine will not vibrate.

[0003] The currently used water squeezing and setting equipment include...

Embodiment Construction

[0019] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0020] A hydraulic press for rapid water extrusion (such as figure 1 shown), including frame 4, slide block 6, oil cylinder 5, hydraulic control system 2, oil supply pipeline 3 and electrical control system 1, slide blocks are installed in parallel guides in the frame, and the frame below the slide block Oil cylinders are evenly distributed on the top, and the oil cylinders are respectively connected with the hydraulic control system through oil supply pipelines. The electrical control system controls each action of the hydraulic control system according to preset instructions. The working form of the hydraulic press is to lift the material, pressurize the water, keep the pressure and set the shape.

[0021] The technical scheme of the hydr...
