Abstract
The utility model discloses a hydraulic device which comprises a cylinder body. A piston is transversely arranged in the cylinder body, two ends of the piston are connected with the inner wall of the cylinder body, the inner wall of the cylinder body is provided with a groove matched with the piston, the lower surface of the piston is provided with a main oil cylinder, the main oil cylinder is fixedly connected with the cylinder body through a spindle and installed on a pull-down oil cylinder, sliding beams are arranged on two sides of the cylinder body, vertically arranged on two sides of the cylinder body and connected through a rotary shaft oil cylinder body, guiding tension columns are arranged on the sliding beams, two ends of the pull-down oil cylinder penetrate the guiding tension columns, the bottom of the pull-down oil cylinder is connected with a main valve oil outlet pipe, an oil outlet of the main valve oil outlet pipe penetrates the pull-down oil cylinder to be in communicated connection with the main oil cylinder, and an oil inlet of the main valve oil outlet pipe is in communicated connection with an auxiliary oil cylinder. Before the hydraulic device is used, air in the cylinder body is emptied, the pull-down oil cylinder provides mold closing force and enables the mold closing force to be large, the main oil cylinder only provides forging pressure for extruding a blank, a forge piece accurate in size can be obtained by extruding and enabling the blank to be filled in a mold cavity, and the hydraulic device is small in size and low in energy consumption.
Description
Technical field
The utility model relates to a kind of mechanical device, particularly a kind of hydraulic means.
Background technology
Block forging is advanced precision forging technology technology in a kind of present age.Block forging is called again inaccessible extruding, its principle is the die cavity that divides die to be closed into a sealing with enough large mold clamping force by two or several, metal blank is under the unidirectional or out movement of one or more drifts, be full of die cavity by extruding, thereby obtain one and the identical fine forge piece of die cavity shape and size.But the space of the flexible member that inaccessible mould bases can hold is very limited, therefore defect to some extent in forging process, and general hydraulic means is before forging, air better cannot be discharged, thus affect forging effect.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provide one can reach size fine forge piece accurately, volume is little, and few hydraulic means that consumes energy.
To achieve these goals, the technical solution adopted in the utility model is such: hydraulic means of the present utility model, comprise cylinder body, in cylinder body, be horizontally set with piston, piston two ends are connected with inboard wall of cylinder block, and on inboard wall of cylinder block, have the groove mating with piston, piston lower surface is provided with master cylinder, master cylinder is fixedly connected with cylinder body by main shaft, master cylinder is arranged on drop-down oil cylinder, cylinder body both sides are equipped with sliding beam, sliding beam vertically arranges cylinder body both sides, and be connected with cylinder body by rotating shaft, sliding beam is provided with guiding pulling force post, drop-down oil cylinder two ends arrange through guiding pulling force post, drop-down oil cylinder bottom connects a main valve flowline, main valve flowline oil-out is connected through drop-down oil cylinder and master cylinder, main valve flowline oil-in and auxiliary oil cylinder are connected, throttle is installed on auxiliary oil cylinder, between throttle and auxiliary oil cylinder, adopt snapping to be connected, auxiliary oil cylinder bottom is provided with a balanced valve, auxiliary oil cylinder both sides are extended at balanced valve two ends, and removably connect with auxiliary oil cylinder.
Further, as a kind of concrete version, cylinder body described in the utility model two ends all have oil inlet and outlet.
Further, as a kind of concrete version, on piston described in the utility model, be connected with piston rod, piston rod one end is through cylinder body.
Further, as a kind of concrete version, cylinder body described in the utility model both sides are also respectively equipped with a steam vent.
Compared with prior art, the utility model has the advantage of: the utility model hydraulic means before use can be by the air emptying in cylinder body, and provide mold clamping force by drop-down oil cylinder, make its mold clamping force more powerful, and master cylinder only provides the forging force of extrusion blank, be full of die cavity by extruding, thereby reach size fine forge piece accurately, volume is little, and power consumption is few.
