Heavy-duty die-forging hydraulic press

Abstract

The invention relates to a heavy-duty die-forging hydraulic press, which comprises an upper transverse beam, a lower transverse beam, four upright posts, pull rods, lock nets, a cylinder-including slide block, a side cylinder and a return cylinder, wherein the lower transverse beam is provided with a movable workbench. The heavy-duty die-forging hydraulic press is characterized in that: the cylinder-including slide block and the four upright posts are provided with guide devices which are matched with one another; the side face of each corner of the cylinder-including slide block is provided with a groove; three adjacent side faces of the grooves are provided with guide rail assemblies; three adjacent side faces of each upright post are provided with fixed guide plates which are matched with the guide rail assemblies so as to construct an entire guide structure of the hydraulic press of which the four corners and twelve faces have eccentric load resistance; and a workbench detection transmitting device is arranged on the lower transverse beam. The heavy-duty die-forging hydraulic press has the advantages that the eccentric load resistance of the press can be enhanced greatly, the press is prevented from being damaged, the service life is prolonged, and user input cost is reduced; and a mechanical transmission way is adopted, so that the use requirement on hot die forging is met, the influence of high temperature is eliminated, accurate detection is realized, and extremely high sensitivity is always kept under high-frequency use conditions. The forging requirements of various types of workpieces are met, the workpiece quality is enhanced, and the production efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of forging machinery, in particular to a heavy-duty die 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 temperature is very...
