Abstract
The utility model discloses a balance cylinder structure for a hydraulic machine. The balance cylinder structure comprises a hydraulic machine body, wherein hydraulic oil cylinders are arranged on the hydraulic machine body, and a sliding block is arranged below the hydraulic oil cylinders. The balance cylinder structure is characterized in that two sides of the upper portion of the hydraulic machine body are respectively provided with a balance cylinder which is connected with the sliding block through a piston rod. According to the balance cylinder structure for the hydraulic machine, in the operating process of the hydraulic machine, the balance cylinders arranged on two sides of the sliding block and are used for increasing suspension push force through inflation, weighting force equal to the weight of the sliding block can be eliminated, moreover motion speed of upward lifting is accelerated, and therefore work efficiency of the hydraulic machine is improved. When the sliding block of the hydraulic machine falls down quickly, in the prior art, the weight of the sliding block and the weight of an upper mold form downward gravitational potential energy, however, in current, the balance cylinder structure is used for counteracting energy required by the weight of the sliding block.
Description
Technical field
The utility model relates to the technical field of hydraulic press, specifically a kind of compensating cylinder structure for hydraulic press, particularly its frame for movement.
Background technology
Documents, the patent No.: CN200820074283.4, the applying date: 2008.04.02, patentee: Tianjin 2nd Forging Press Factory; This case discloses a kind of " the four post high-precision hydraulic machines that have pressure and Stroke Control and checkout gear ", comprise fuselage, master cylinder, the hydraulic power box that is connected with master cylinder by pipeline and be positioned at the electric control box that the fuselage opposite side connects by lead, it is characterized in that: described fuselage is by entablature, workbench and four columns are by the fixing formation of locking member general frame structure, master cylinder is installed in the entablature, the master cylinder piston end is fixed with pressure-detecting device, pressure-detecting device is connected in aggregates with slide block, fuselage one side is provided with device for detecting distance of travel, the master cylinder upper oil cavitie, lower oil cavitie connects the pressure oil outlet of ratio hydraulicdirectional control valve respectively by pipeline, the oil-in of ratio hydraulicdirectional control valve is connected with hydraulic oil pump pressure oil outlet on being installed in hydraulic power box, and hydraulic oil pump exports proportional pressure valve is housed.
Hydraulic press when production field uses does not all have the setting of compensating cylinder structure at present, and it is long conversion time to exist hydraulic system pressure, causes slow shortcoming of the slider of hydraulic press period of motion, need overcome the slide block own wt in addition, and the energy that consumes is bigger.After having increased compensating cylinder, compensating cylinder has played the effect of an energy storage, with rational balance the energy that consumes of slider of hydraulic press own wt.And increased the conversion speed of hydraulic system, thereby played energy-conservation and effect synergy.
Summary of the invention
The purpose of this utility model is to provide a kind of compensating cylinder structure for hydraulic press, and the art of this patent is in the both sides of top beam of hydraulic machine two bigbore compensating cylinders to be installed, and the piston rod of compensating cylinder links to each other by hanging feet with the slide block of hydraulic press and is fixedly connected.The air accumulator that compensating cylinder is used by pipe-line system and energy storage is connected.Compressed air inside the downward compensating cylinder of slide block can be compressed to and carry out energy storage in the air accumulator, when the slider of hydraulic press backhaul, and the compressed air in the air accumulator, the piston that promotes compensating cylinder moves upward.And discharge its energy, making hydraulic press send out slide block can move upward fast.Whole process is compared and is not used the needed time of compensating cylinder to shorten about 2/3.So effect is significantly, has overcome the shortcoming and defect that exists in the prior art.
To achieve these goals, the technical solution of the utility model is: a kind of compensating cylinder structure for hydraulic press, it comprises the hydraulic press body, hydraulic press body place is provided with hydraulic jack, the hydraulic jack bottom is provided with slide block, it is characterized in that: the both sides on described hydraulic press body top respectively are provided with a compensating cylinder, and compensating cylinder is connected with slide block by piston rod.
This case discloses a kind of compensating cylinder structure for hydraulic press, in the hydraulic press running, compensating cylinder by the installation of slide block both sides, inflate the pulling of the pulling force that suspends, can save the Lifting Capacity that is equivalent to slide block weight, and accelerate the movement velocity upwards lift, thereby improved the operating efficiency of hydraulic press.When slider of hydraulic press falls downwards fast, formed a downward gravitional force by slide block weight and patrix weight two parts originally, owing to adopted the compensating cylinder structure, overcome a slide block weight energy needed now.A gravitional force that has only patrix weight to produce also can fall as freely falling body is downward.When slide block is lifted in backhaul, saved about time more than 3 times, accelerated the speed of slide block movement.And required energy when having saved the slide block backhaul has been saved the electric energy that hydraulic press equipment consumes.Productive temp when also having improved simultaneously the hydraulic press operation has improved device efficiency.So the market prospects of the art of this patent are clearly.
