Problems solved by technology

[0003] However, in the actual production process, the following problems will occur when the hydraulic press is running: 1. When the hydraulic press is working, its body will shake, and the unloading valve block will frequently fall off whether it is bolted or welded; 2. The temperature of the press body is high , the hot air rises, the unloading valve controls the lower circuit and the electromagnetic components are easily damaged; 3. When the unloading valve block breaks down for emergency repair or daily equipment inspection, it must be shut down, the crane and the hoisting cage must be used, which takes up a lot of time and affects production; 4. Due to the small space at the top of the press, regardless of the workload, only one person can operate it, and the risk factor is high

Embodiment Construction

[0011] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.

[0012] figure 1 Shown is a schematic diagram of the position of the unloading valve block of the prior art hydraulic press. The unloading valve block 1 is located at the top of the hydraulic press near the oil inlet of the oil cylinder 2. When the pressure is released, the high-pressure oil leaks into the oil tank 8 at the upper end of the unloading valve block 1; the present invention Program such as figure 2 As shown, the unloading valve block 1 is set on the hydraulic pump station 4, and the tee 6 is welded on the oil pipeline 3 near the oil outlet of the hydraulic pump station 4, and the tee 6 passes through the pipeline 5 and the inlet of the unloading valve block 1 Connected, the outlet of the unloading valve block communicates with the hydraulic pump station 4 through the pipeline 7. When the pressure is released, the high-pressure oil is d...

Abstract

The invention discloses a large heavy-duty open die forging oil press unloading system, and belongs to a large heavy-duty open die forging oil press hydraulic system. The hydraulic system comprises an unloading system with an unloading valve block, an oil cylinder, a hydraulic pump station and an oil conveying pipeline communicated with the hydraulic pump station and the oil cylinder. The hydraulic system is characterized in that the unloading valve block is arranged on the hydraulic pump station or near the hydraulic pump station, an inlet of the unloading valve block is communicated with the oil conveying pipeline, and an outlet of the unloading valve block is communicated with the hydraulic pump station.

Description

technical field [0001] The invention relates to the field of press unloading, in particular to the position placement of unloading valve blocks of hydraulic presses used for large and heavy punching and forging, and specifically relates to the unloading system of large and heavy free forging hydraulic presses. Background technique [0002] With the continuous development of my country's industrialization and the continuous improvement of the manufacturing industry, the requirements for the comprehensive performance and production efficiency of the workpiece are also getting higher and higher. In this case, various punching and forging hydraulic presses are widely used. Playing an important role, so various hydraulic machine manufacturers are constantly striving to improve the design level of their own hydraulic machines to meet market demand, but manufacturers often focus on the improvement of large parts, while ignoring small but effective improvements, such as the unloading ...
