Load-deflection resistant loading system for free hydraulic forging press

Abstract

The invention discloses a load-deflection resistance loading system for a free forging hydraulic press, and relates to the forging hydraulic press. The invention solves the problem that in the conventional loading system for the free forging hydraulic press, as a plunger and a movable cross beam are in rigid connection, the movable cross beam is subjected to eccentric load in the eccentric forging process to accelerate abrasion of a guide copper sleeve and a seal to cause earlier failure and leakage of seal of a main working cylinder so as to cause poor eccentric forging resistance of the loading system. The loading system for transmitting forging pressure of the free forging hydraulic press is characterized in that the combination movable cross beam with an overlong guide structure, fully enclosed wedge-shaped plane guide devices which can adjust gaps of the peripheries of upright posts, a double concave ball hinged short cylindrical rocker shaft device of which the main plunger is connected with the movable cross beam, and a levelness sensor monitoring device of the movable cross beam are adopted on the free forging hydraulic press. The load-deflection resistant loading system not only can be applied to various free forging hydraulic presses, but also can be popularized and applied to other vertical hydraulic presses suitable for the process.

Description

technical field [0001] The present invention relates to forging hydraulic presses. In particular it relates to the loading system of free forging hydraulic presses. Background technique [0002] Free forging hydraulic press is the key equipment widely used in forging production. In the traditional three-beam four-column free forging hydraulic press, the plunger of the main working cylinder of the loading system and the movable beam are mostly rigidly connected, and the lower end of the plunger is directly inserted into the movable beam and fixed with a gland and bolts. In mechanical analysis and calculation, it is often assumed that there is no lateral horizontal reaction force at the forging, which does not hinder the rotation of the movable beam; the gaps between the guide sleeves of the tension columns on both sides are the same, and when the movable beam is tilted by eccentric load, the tension columns on both sides are affected. Even force. [0003] In actual product...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art, provide a loading system for free forging hydraulic presses against partial load, and solve the problem of the traditional three-beam four-cylindrical free forging hydraulic press, because the main plunger and the movable beam of the loading system are rigidly connected, During eccentric forging, the movable beam is subjected to eccentric load, which intensifies the wear of the guide copper sleeve and seal, leading to early failure and leakage of the main working cylinder seal, and even damages and breaks the column, resulting in the problem of poor anti-eccentric forging ability of the loading system
