An anti-eccentric load device for a precision hot die forging press

Abstract

The invention relates to the technical field of forging mechanical presses, in particular to an anti-unbalance-loading device of a precise hot die forging press. The anti-unbalance-loading device comprises a rack, a working table plate and a sliding block body, wherein the rack is of an integral cast steel box type frame symmetrical structure, and a symmetrical cage type is formed through a transverse plate; a positioning key is arranged at the bottom of the working table plate and fixed to the rack; the sliding block body is of an integral cast steel structure, and a long octahedral guide rail is arranged on the sliding block body; the guide rail on the front side, the guide rail on the right side and the guide rail on the rear side are 90-degree straight guide rails, and guide rails at the front and the rear of the left side are inclined guide rails; and a left-right gap adjusting mechanism is arranged on the left side of the inside of the rack, and a front-back gap adjusting mechanism is arranged on the front side of the inside of the rack. The anti-unbalance-loading device has the beneficial effects that the rigidity of the whole machine is remarkably improved, the guide precision of the sliding block is improved, and the anti-unbalance-loading capacity is high; and meanwhile, the weight of the whole machine can be reduced, green material saving is achieved, the operation precision and the forging quality are improved, and the remarkable effects of improving the precision, rigidity, efficiency and green material saving of the hot die forging mechanical press and an automatic production line are achieved.

Description

Technical field: [0001] The invention relates to the technical field of forging mechanical presses, in particular to an anti-eccentric load device for precision hot die forging presses. Background technique: [0002] Currently, existing mechanical presses such as figure 1 As shown, the frame and slider are one of the main components of the hot die forging press. The frame and slider guides of the traditional structure mostly use 45° inclined guide rails, which are distributed around the slider. Professionals need to adjust the gap during installation. , in order to ensure the accuracy of the machine tool, and when the hot forging press is thermoforming, the workpiece needs to be heated to a constant temperature of 800-1000°C, which has high requirements for the rigidity of the frame and slider. The 45° inclined guide rail will expand and deform in a high temperature environment, which will easily cause the gap between the slider guide rail to become smaller, which will caus...

Problems solved by technology

[0004] In order to make up for the deficiencies in the prior art, the present invention provides an anti-offset load device for a precision hot forging press, which solves the problem of precision improvement restricted by the insufficient rigidity of the hot forging press and the automation line frame, and solves the problem of heavy offset The problem that the guide rail of the rack is prone to displacement and affects the accuracy of the machine tool under the action of load has solved the problem that the thread of the adjustment bolt of the slider guide rail is damaged due to eccentric load at the bottom dead point and cannot be adjusted or disassembled. The fastening of bolts under the action of force will easily cause the problem that the displacement of the worktable affects the accuracy
