Servo- pressing machine

Abstract

The invention discloses a servo press mechanism, a sliding device is arranged between a beam of a machine body and a mainshaft bracket and connected with connecting rod brackets through pull rods, the connecting rod brackets are connected with the beam of the machine body through upper connecting rods; and meanwhile, the connecting rod brackets are connected with slide block through lower connecting rods, and two sets of push rods, connecting brackets, upper connecting rods and lower connecting rods are symmetrically arranged along the sliding device; a servo motor drives the sliding device to slide up and down, and the sliding device drives the connecting rods to swing through the push rods; and meanwhile, the connecting rod brackets drive the slide block to move up and down through the lower connecting rods, thereby the pressure processing to a workpiece made of metal or nonmetal materials is finished. In the invention, each connecting rod in a motion branch chain adopts a parallelogram structure so that the connecting rod brackets at two sides and the slide block can be always kept in a horizontal state during the moving process, thereby the overturning freedom degree of the movement of the slide block is eliminated; and four support points are arranged between the beam of the machine body and the slide block, thereby the unbalance-loading resistance capacity is improved, and the slide block in the work can be ensured to move more stably.

Description

technical field [0001] The invention is used in the field of metal or non-metal pressure processing, especially a servo press mechanism. Background technique [0002] Forging production occupies an extremely important position in the defense industry and civilian industry. The plastic forming of the forging process moves the material faster than the cutting process, and the production efficiency is high; it can improve the internal structure and defects of the material, and improve the mechanical properties of the parts; the parts are light in weight and the material utilization rate is high. Therefore, the number of parts processed by forging and pressing accounts for a large proportion in all walks of life. With the development of modern society, there are more and more individualized social needs, which requires that the products produced by enterprises must be diverse, so the production equipment also requires high flexibility and can produce products of various specifi...

Problems solved by technology

However, in the toggle mechanism designed for these two servo presses, the slider will have a redundant rotational degree of freedom without the constraint of the slider guide rail. This redundant rotational degree of freedom is completely constrained by the guide rail, which is easy to make the guide rail Movement accuracy affected by wear

In addition, there are only two fulcrums of the symmetrically arranged double toggle mechanism, and the anti-eccentric load capacity is not strong, which affects its stiffness.
