Large eccentric load multifunctional forging hydraulic machine

Abstract

The invention relates to a large eccentric load multifunctional forging hydraulic machine. The large eccentric load multifunctional forging hydraulic machine is composed of upper cross beams, lower cross beams, four stand columns, pull rods, nuts, a sliding block with a cylinder, a side cylinder and a return cylinder. A movable workbench is arranged on the lower cross beams. The forging hydraulic machine is characterized in that the sliding block with the cylinder and the four stand columns are provided with mutually matched guiding devices; the side faces of all corners of the sliding block with the cylinder are each provided with a groove; the three side faces adjacent to each groove are each provided with a guide rail assembly, and the three side faces adjacent to each stand columns are each provided with a fixing guide plate matched with the corresponding guide rail assembly, so that a four-corner twelve-face overall guiding structure with the anti-eccentric load capacity of the hydraulic machine is formed; and a workbench detecting transmission device is mounted on the lower cross beams. The hydraulic machine has the advantages that the anti-eccentric load capacity of a press can be greatly improved, the hydraulic machine is prevented from being damaged, the service life is prolonged, and the user input cost is lowered; a mechanical transmission mode meets the hot die forging using requirement and is accurate in detection without being influenced by high temperatures, and the quite high sensitivity is maintained all the time under the high frequency application working condition. The forging requirements of various workpieces are met, and the workpiece quality and production efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of forging machinery, in particular to a large partial load multifunctional forging hydraulic press. Background technique [0002] At present, hot die forging presses have been widely used in the manufacturing and processing of automobile hubs and aviation parts. According to different forging processes of different workpieces, the forging temperature is constantly increasing from 100-900 °C. When the working table of the hot die forging press is moved into the press and then falls, it is necessary to check whether the bonding surface of the working table and the lower beam is completely attached through the signaling device. If the bonding is not in place, the press continues to work, which will cause Severely damaged, in severe cases, the device cannot be used normally. The drop-in-position signaling device of the traditional press is to install the detection switch on the lower beam, but when the forging...

AI Technical Summary

Problems solved by technology

The traditional hot die forging hydraulic press generally adopts four-corner and four-sided guide structure to overcome the working conditions that often cause high unbalanced loads. However, the aforementioned guide structure will cause serious damage to the fuselage during use, not only affecting the quality of the workpiece and production efficiency. Cause a certain impact, the workpiece after forging and forming cannot meet the requirements of use; and it will also shorten the service life of the hydraulic press and increase the production cost of the user
