Abstract

The invention relates to a heavy-duty isothermal forging hydraulic press, which comprises an upper transverse beam, a lower transverse beam, upright posts, a main cylinder, side cylinders and a slide block, wherein an upper baseplate is fixed on the lower plane of the slide block; and a movable workbench is arranged on the lower transverse beam. The heavy-duty isothermal forging hydraulic press is characterized in that the upper transverse beam and the lower transverse beam form a combined beam body structure; leveling cylinders are fixed on the four corners of the upper end of the upper transverse beam and the upper end of the lower transverse beam; each leveling cylinder is provided with an independent leveling control system; an upper knock-out device is arranged on the slide block; movable workbench positioning mechanisms are arranged on the lower part of the movable workbench body and in the lower transverse beam; and the movable workbench body is further provided with a movable workbench clamping device. The heavy-duty isothermal forging hydraulic press is characterized in that a combined transverse beam is light in weight and is convenient to transport and produce, and the manufacturing cost can be reduced; a leveling effect is achieved via the leveling cylinders, the leveling response time is shortened, and energy is saved greatly; through the upper knock-out device, successful demolding of workpieces can be realized, and the workpiece forging and pressing quality is ensured; and accurate positioning and stable running of a press workbench can be realized, and the production requirement of forging equipment for heavy-duty aviation forgings is met.

Description

technical field

[0001] The invention belongs to the technical field of forging machinery, in particular to a heavy-duty isothermal forging hydraulic press. Background technique

[0002] With the development of modern industry, titanium alloys are widely used in various fields. At present, isothermal forging presses and isothermal forging processes are generally used to produce large titanium alloy parts. Isothermal forging presses and forging processes not only have high production efficiency, but also have high precision and structure density for titanium alloy forgings formed by isothermal forging. In the isothermal forging process, after the blank is heated at a certain temperature, it is put into the preheated mold for high-precision forging. The isothermal forging press compensates the heat lost by the workpiece during the low-speed extrusion process, so that the workpiece is kept at a very stable temperature. The forging process is completed in the interval, and the i...
