Hydraulic pressure pressing machine with multiple connecting rods

Abstract

The invention discloses a multiple-link hydraulic pressure press. The press includes a bed, two same multiple-link fork chains, a punch hammer, a fluid cylinder, wherein the two fork chains are positioned on two sides of the fluid cylinder symmetrically, a worktable is fixed on the bed, the bed connects with punch hammer through the fork chains to form a closed structure, the fork chains locks the two parallelogram agencies through intermediate components, and the punch hammer connects with the bed by a kinematic pair. The link and punch hammer of the invention have four supporting points to steady the movements of the punch hammer and overcome the influence of the accuracy caused by eccentrically load. The invention uses one fuel tank to drive to produce the power output which is equal to the power output produced by a plurality of equal fuel tanks, and overcomes the control problem of harmonizeing of a plurality of fuel tanks.

Description

a technical field [0001] The invention belongs to pressure processing technology, in particular to a multi-link hydraulic press. Two background technology [0002] In the field of pressure processing, when the nominal pressure is not large, a multi-link mechanical press is generally used to meet the production requirements; when the nominal pressure is relatively large, it is usually difficult for the mechanical press driven by the motor to provide the required power. , At this time, a hydraulic press is generally used instead of a multi-link mechanical press. The advantage of the multi-link press is that through the optimized design of the mechanism, the force-increasing function can be realized, and the efficiency is relatively high. The disadvantage is that the multi-link structure is complex and difficult to design. In addition, the connection between the hammer and the bar of the multi-link press is realized through a spherical joint. The fulcrums of the connecting rod...

Problems solved by technology

The method of increasing the diameter of the oil cylinder will cause many other problems, such as the control problem of the electro-hydraulic servo system with large flow and large flow difference; the method of connecting multiple hydraulic cylinders needs to control the synchronous and coordinated movement of multiple oil cylinders, which is also an unreasonable easy problem to solve
