Abstract
The utility model discloses a large gantry travelling type hydraulic press compound oil cylinder. The upper part of the oil cylinder body of a primary plunger piston oil cylinder thereof is connected with an oil cylinder elongated back cover by a bolt; the lower part of the oil cylinder elongated back cover is connected with an oil cylinder front cover; the primary plunger piston oil cylinder is connected with an upper work bench; a piston is sealed inside the oil cylinder body by a sealing piece; the two sides of the primary oil cylinder are connected with two assistant step-up oil cylinders symmetrically by a ring flange arranged on the oil cylinder body; the piston head of the assistant step-up oil cylinder is connected with the upper work bench by threads; the ring flange is provided with two guide levers which are connected with the assistant step-up oil cylinder coaxially and are provided with a guide sleeve; and the guide levers are arranged on the upper work bench. The utility model has the advantages of simple and compact structure and reasonable design. Because the device is adopted, an oil pump and all hydraulic devices realize low capacity and high speed action; both the downward speed and the rebound speed of the oil cylinder can meet the production requirement; consequently, the labor efficiency of an oil hydraulic press is improved.
Description
Technical field
The utility model belongs to the master cylinder of large-sized gantry mobile hydraulic machine and makes field, particularly a kind of large-sized gantry mobile hydraulic machine composite oil cylinder.
Background technology
In middle-size and small-size hydraulic press in the past, adopt a piston cylinder just can satisfy and produce needs, and in large-sized hydraulic press, have following problem: large-tonnage, High Voltage require high to structure, the hydraulic control of oil cylinder; Downstream rate and return speed are slow, and the control of the speed of service can not be satisfied needs of production, so just greatly reduce production efficiency.
Summary of the invention
The purpose of this utility model provides a kind of quick descending and return speed that can accelerate oil cylinder, and can realize the accurately large-sized gantry mobile hydraulic machine composite oil cylinder of control of oil cylinder position.
To achieve these goals, the technical scheme that the utility model is taked is: a kind of large-sized gantry mobile hydraulic machine composite oil cylinder, the cylinder body top of its main plunger oil cylinder is connected with oil cylinder lengthening bonnet by screw, described oil cylinder lengthening bonnet bottom is connected with the oil cylinder protecgulum, described main plunger oil is connected with upper table, be sealed with plunger by seal in the described cylinder body, described master cylinder bilateral symmetry must be connected with two auxiliary speedup oil cylinders by the ring flange that is located on the cylinder body, the piston head of described auxiliary speedup oil cylinder is threaded with upper table, also be provided with on the described ring flange and coaxial two guide posts that have fairlead that are connected of auxiliary speedup oil cylinder, guide post puts together on the upper table.
The composite oil cylinder that the utility model provides, simple and compact for structure, reasonable in design, use this device, can make and realize low capacities and can high speed motion from oil pump to whole hydraulic means, and oil cylinder downstream rate and return speed all can be satisfied produce needs, thereby improve workman's efficient of hydraulic press.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
As shown in Figure 1, a kind of large-sized gantry mobile hydraulic machine composite oil cylinder, cylinder body 2 tops of its main plunger oil cylinder are connected with oil cylinder lengthening bonnet 1 by screw, described oil cylinder lengthening bonnet 1 bottom is connected with oil cylinder protecgulum 5, described main plunger oil is connected with upper table 6, be sealed with plunger 3 by seal in the described cylinder body 2, described master cylinder bilateral symmetry must be connected with two auxiliary speedup oil cylinders 4 by the ring flange that is located on the cylinder body 2, the piston head of described auxiliary speedup oil cylinder 4 is threaded with upper table, also be provided with on the described ring flange and auxiliary speedup oil cylinder 4 coaxial two guide posts 7 that have fairlead that are connected, guide post 7 puts together on the upper table 6.
When pump start, at first be two auxiliary speedup cylinder 4 rodless cavity oil-feeds, the rod chamber oil extraction, by the quick downstream rate of one-way throttle valve regulation rod chamber, main plunger oil cylinder prefill valve is opened by suction, carry out fluid infusion, driving upper table 6 drives into fast, when pressure head is run into the speed change-over switch, main plunger oil cylinder and the oil-feed simultaneously of auxiliary speedup oil cylinder 4 rodless cavities, counterbalance valve cuts out, and auxiliary speedup oil cylinder 4 rod chamber fluid are by the counterbalance valve oil return, speed at this time is converted to the worker to be advanced, and auxiliary cylinders and plunger case are descending at a slow speed to be suppressed.After having suppressed, the oil-feed of auxiliary cylinders rod chamber, the plunger case release, upper table returns rapidly.
The oil cylinder speeder that the utility model provides is formed the principal pressure system by oil cylinder lengthening bonnet 1, cylinder body 2, plunger 3, oil cylinder protecgulum 5, upper table 6, mainly workpiece is suppressed, auxiliary speedup oil cylinder 4 is selected two overload hydraulic cylinders for use, by the cylinder body flange, symmetric arrangement, rod chamber one side of auxiliary speedup oil cylinder 4 is connected with upper table 6, the main descending and quick return fast that rises.Guide post 7 links together by fairlead and cylinder body 2, upper table 6 whole system is played the guiding stabilization.
Above-described only is preferred embodiment of the present utility model.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the utility model,, can also make other equivalent modifications and improvement, also should be considered as protection domain of the present utility model as the common practise of mechanical field.
