Anti-eccentricity pressing piston rod connecting device of no-guiding slider type hydraulic press

Abstract

The invention belongs to the mechanical manufacturing field. The anti-eccentricity pressing piston rod connecting device of a no-guiding slider type hydraulic press relates to a piston rod and a working slider of a hydraulic cylinder and is characterized in that: the connecting device comprises a bolt, a pressing flange, a fixed support and a hinged support; a piston rod radial through hole is arranged in the middle part of the pressing flange, the aperture of the piston rod radial through hole is 3-5mm more than that of the radial part of the piston rod, a hinged support mounting hole is arranged in the middle part of the fixed support, and the aperture of the hinged support mounting hole is 3-5mm more than the maximum diameter of a piston rod ball head, the fixed support is welded on the working slider, and the hinged support is arranged in the hinged support mounting hole of the fixed support, the radial part of the piston rod penetrates through the piston rod radial through hole on the pressing flange, the radial part of the piston rod is arranged in a space surrounded by the pressing flange, the fixed support and the hinged support, and the pressing flange and the fixed support are fixed by a bolt; and the connecting device can effectively avoid damage to mechanical equipment, caused by eccentric pressing.

Description

Technical field [0001] The invention belongs to the field of mechanical manufacturing, and particularly relates to a hydraulic press for large-pressure and large-span spherical tank flaps (a hydraulic machine for manufacturing molded components), and in particular to a connection between a piston rod and a working slider of a non-guided slider type hydraulic press Device. Background technique [0002] The spherical tank is a large-capacity, pressure-bearing steel spherical storage container, which is widely used in petroleum, chemical, metallurgical and other sectors. It can be used as a medium for liquefied petroleum gas, liquefied natural gas, liquid oxygen, liquid ammonia, liquid nitrogen and other media. Storage container. The structure of the spherical container is composed of two parts: a spherical shell and a support. The spherical shell is assembled and welded by many spherical flaps. Due to the large geometry of the spherical storage tank and the transportation restrict...

AI Technical Summary

Problems solved by technology

[0004] Affected by the resultant force in the horizontal and vertical directions, the pressure on the flange thread connection between the hydraulic press piston and the working slider is uneven, and the force point of the piston is offset, which can easily lead to damage to the thread of the piston rod, damage to the guide sleeve of the cylinder port, and damage to the bolts. Cutting accidents occur, the light ones damage the mechanical equipment, and the serious ones lead to work-related accidents
