Structural rigidity and precision improving device for hot die forging press

Abstract

The invention relates to the technical field of forging mechanical presses, in particular to a device for improving the structural rigidity and precision of a hot die forging press. The device comprises a machine frame, a working table and a slider body. An overall cast steel box type frame symmetrical structure is adopted for the machine frame, and a symmetrical cage type structure is formed through an X-shaped connecting plate. The bottom of the working table is provided with positioning pins and bolts so that the working table can be fixed to the machine frame. The slider body is of an overall cast steel structure and is provided with long octahedral guide rails, wherein the guide rails on the front side, the right side and the rear side are 90-degree straight guide rails, and the frontand back guide rails on the left side are inclined guide rails. The left side in the machine frame is provided with a left-right gap adjusting mechanism. The front side in the machine frame is provided with a front-back gap adjusting mechanism. The device has the advantages that the dynamic rigidity of the whole machine is remarkably improved and a slider is high in guide precision and unbalanceloading resistance; and meanwhile, the weight of the whole machine can be reduced, the operation precision and the quality of forge pieces are improved, the precision forging of special-shaped complicated pieces of the hot die forging press is realized, and the effects of effectively improving the rigidity, being high in efficiency and green and saving materials are realized.

Description

Technical field: [0001] The invention relates to the technical field of forging mechanical presses, in particular to a device for improving structural rigidity and precision of hot 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, whi...

Problems solved by technology

[0004] In order to make up for the deficiencies in the prior art, the present invention provides a hot die forging press structural rigidity and precision improvement device, which solves the key technical problem of precision improvement restricted by the insufficient rigidity of the hot forging press and the automation line frame, and solves a major problem. Under the action of eccentric load, the guide rail of the rack is prone to displacement and affects the accuracy of the machine tool. It solves the problem that the thread of the adjustment bolt of the slider guide rail is damaged at the bottom dead point due to eccentric load and cannot be adjusted or disassembled. The load effect only depends on the bolt fastening, which may easily cause the displacement of the worktable to affect the positioning accuracy.
