Abstract
The utility model provides an oil cylinder device of a hydraulic press, which comprises an oil cylinder and a piston rod, wherein the oil cylinder is a double oil cylinder. The double oil cylinder is characterized in that two oil paths are arranged separately on the piston rod, an inner cavity is arranged in the piston rod, a small piston rod is sealed and connected to the inside of the inner cavity via a sealing ring, the inner cavity is divided into an upper cavity and a lower cavity by the small piston rod, and the upper cavity and the lower cavity are respectively communicated with the two oil paths. By adopting a built-in mode, arranging a small piston inside the piston rod and using the hollow inner cavity as a cylinder body, the oil cylinder device can save space and meet requirements of different processes, which is particularly adaptable to manufacturing of stair-like products.
Description
Technical field
The utility model relates to a kind of hydraulic press, is specifically related to a kind of conserve space, and the cylinder apparatus of the hydraulic press of energy simultaneous adaptation kinds of processes.
Background technology
Hydraulic press in the market is a lot, and range of application is also very extensive, and still different goods also have nothing in common with each other to the requirement of press, if for each based article is made a hydraulic press to measure, obviously very waste, if but do not make to measure, the minor variations of some like products can't realize again.
The utility model content
Main task of the present utility model is to provide a kind of cylinder apparatus of hydraulic press, specifically is a kind of conserve space, and the cylinder apparatus of the hydraulic press of energy simultaneous adaptation kinds of processes.
In order to solve above technical problem, the cylinder apparatus of a kind of hydraulic press of the present utility model is made of oil cylinder and piston rod, it is characterized in that: be two oil cylinders at described oil cylinder.
Described pair of oil cylinder be for to set up two oil circuits separately and piston rod is drawn into an inner chamber on piston rod, by the sealing ring small piston rod that is tightly connected, described inner chamber is divided into two chambeies up and down by small piston rod in inner chamber, and described two chambeies up and down are communicated with formation with two oil circuits respectively.
The advantage of above structure is: establish valve piston in piston rod, the inner chamber of emptying is made cylinder body, adopt built-in mode, promptly saved the space, adapted to the requirement of different process again, be particularly suitable for the making of notch cuttype goods.
Description of drawings
Figure is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, in the piston rod 2 of oil cylinder 1, establish oil circuit 3,4, again piston rod 2 drawn into an inner chamber, in inner chamber by sealing ring 6 small piston rod 7 that is tightly connected.Described small piston rod 7 is divided into upper and lower cavity 8,9 by sealing ring 6 with inner chamber, and above-mentioned oil circuit 3,4 is communicated with respectively at upper and lower cavity 8,9, and like this, the part that piston rod 2 is emptied just becomes the small oil tank of a repacking.
During work, if only need use oil cylinder 1, the small oil tank of that repacking is with regard to transfixion, if arts demand needs the small oil tank with repacking, if turnover hydraulic oil, just valve piston 7 can be worked.This structure compact, the repacking small oil tank just leaves standstill in it when not using, and need not to shirk, and during use, unlatching can be used, and is practical and convenient.
Claims (2)
1, a kind of cylinder apparatus of hydraulic press is made of oil cylinder and piston rod, it is characterized in that: be two oil cylinders at described oil cylinder.
2, the cylinder apparatus of a kind of hydraulic press according to claim 1, it is characterized in that: described pair of oil cylinder is for to set up two oil circuits separately and piston rod is drawn into an inner chamber on piston rod, in inner chamber by the sealing ring small piston rod that is tightly connected, described inner chamber is divided into two chambeies up and down by small piston rod, and described two chambeies up and down are communicated with formation with two oil circuits respectively.
