Heavy-duty isothermal forging press with four corner leveling function

Abstract

The invention relates to a heavy-duty isothermal forging press with a four corner leveling function. The heavy-duty isothermal forging press with the four corner leveling function comprises an upper transverse beam, a lower transverse beam and a stand column which are connected through tie rods and lock nuts to form an integrally stressed frame body, wherein the upper transverse beam is fixed with the bottoms of a main cylinder and a side cylinder, piston ends of the main cylinder and the side cylinder are fixedly installed with a sliding block, an upper cushion plate is fixedly arranged on a lower plane of the sliding block, and a movable workbench is installed on the lower transverse beam. The heavy-duty isothermal forging press with the four corner leveling function is characterized in that upper leveling cylinders are fixedly arranged at four corners of the upper transverse beam, lower leveling cylinders are fixedly arranged on the lower transverse beam at positions corresponding to the upper leveling cylinders on the upper transverse beam, and each of upper leveling cylinders and lower leveling cylinders has an independent leveling control system. The heavy-duty isothermal forging press with the four corner leveling function has the advantages that since the pressure of the leveling cylinders at a certain corner of the sliding block is controlled to be increased or decreased through a control loop and the leveling cylinders at the opposite corner are simultaneously controlled, the levelness of the sliding block in the downward forging process is guaranteed; not only can the leveling response time be shortened and can the sliding block leveling accuracy and production efficiency be improved, but also the loss of the main tonnage of a hydraulic press can be avoided, the energy can be greatly saved and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of forging presses, in particular to a heavy-duty isothermal forging press with four-corner leveling functions. Background technique [0002] With the development of the titanium alloy industry, the specifications of forgings are getting larger and larger, and the tonnage of corresponding presses is also increasing. The demand for presses for some aviation forgings has exceeded 20,000 tons. Precision requirements are getting higher and higher. At present, the typical structure of the hydraulic press used for processing titanium alloy is three beams and four columns. The layout of the main cylinder and slider of the hydraulic press is that four main cylinders are installed in the middle of the upper beam, and the slider is connected with the plunger of the main cylinder. 1. Columns are installed between the workbench and the lower beam. The slider moves up and down along with the four columns under the drive...
