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

Embodiment Construction

[0019] In order to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the embodiments and accompanying drawings, see figure 1 , image 3 , Figure 4 , Figure 5 :

[0020] The anti-eccentric pressing piston rod connecting device of the non-guided slider hydraulic press involves the piston rod 2 and the working slider 3 of the hydraulic cylinder. The connecting device includes bolts 6, compression flanges 7, fixed supports 8, and hinged supports 9. A piston rod diameter through hole 12 is provided in the middle of the compression flange 7, and the diameter of the piston rod diameter through hole 12 is 3 to 5 mm larger than the diameter of the piston rod diameter 11 (and the diameter of the piston rod diameter through hole 12 is smaller than the maximum diameter of the piston rod ball head 10), the compression flange 7 is provided with a plurality of bolt through holes 13 (the plurality ...

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 in particular relates to a hydraulic press (hydraulic machine for manufacturing forming components) for large-pressure and large-span spherical tank flaps, and in particular to a connection between a piston rod and a working slider of a non-guiding slider 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 departments. It can be used as a container 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 welded by many pieces of spherical valves. Due to the large geometry of the spherical storage tank and the limitation of tran...
