Abstract
The utility model relates to a hydraulic ejector, which comprises a hydraulic cylinder, a material ejection bracket, a material ejection rod, a lower guide sleeve and an upper guide sleeve, wherein, one end of the hydraulic cylinder is installed on a hydraulic cylinder seat, and the other end of the hydraulic cylinder is installed at the bottom part of a workbench base of a pressing machine; the material ejection rod is upwards driven by a piston rod of the hydraulic cylinder; the lower guide sleeve used for guiding the material ejection rod is installed at the lower part of the workbench base; and the upper guide sleeve used for guiding the material ejection rod is installed at the upper part of the workbench base. The hydraulic ejector has the advantages of compact structure, convenient operation, high material ejection precision, high ejecting force, easy demoulding of forgeable pieces, safety and reliability, stable operation, high transmission efficiency and long service life, and can be widely applied to screw presses.
Description
Technical field
The present invention relates to a kind of hydraulic pressure ejector, can be widely used in the fly press.
Background technology
Existing Lifting Device is generally pneumatic liftout, and liftout power is little, and liftout is unreliable, often locates to occur not push up the situation of workpiece, the liftout weak effect.
Summary of the invention
The object of the present invention is to provide that a kind of compact conformation, easy to operate, liftout precision height, ejecting force are big, forging is easy to the demoulding, safe and reliable, operate steadily, the hydraulic pressure ejector of transmission efficiency height, long service life.
In order to achieve the above object, hydraulic pressure ejector of the present invention, comprise hydraulic jack, the liftout carriage that one end is installed on the hydraulic jack seat, the other end is installed in press bench base bottom, the ejector beam that upwards drives by hydraulic cylinder piston rod, be installed in the table base bottom, be used for the following fairlead that ejector beam leads, be installed in table base top, be used for the last fairlead that ejector beam leads.
Hydraulic pressure ejector of the present invention, its operation principle is: be installed in press frame workbench below, with forcing press action frequency coupling, independently finish the inloading part action.Drive ejector beam by hydraulic cylinder piston rod and move up, the forging in the counterdie is ejected, the oil cylinder piston bar resets then, and ejector beam falls, and finishes a working cycles.
Hydraulic pressure ejector of the present invention owing to adopt Driven by Hydraulic Cylinder, is compared with air cylinder driven, and structural volume is little, compact, and response is fast, the transmission efficiency height, and the pressure loss is little, reliable in action.And oil pressure pressure is big, and liftout power is big, solves the problem of die forging demoulding difficulty.
Hydraulic pressure ejector of the present invention, owing to adopt upper and lower fairlead guide-localization, the ejector beam operation is accurate, liftout precision height.
Hydraulic pressure ejector of the present invention, owing to adopt oil pressure actuated, easy to operate, the stationarity height transmits motion accurately and reliably, and transferring power is big, and ejecting force is big, and is safe and reliable, operates steadily long service life.
In sum, hydraulic pressure ejector of the present invention, compact conformation, easy to operate, liftout precision height, ejecting force is big, and forging is easy to the demoulding, and is safe and reliable, operates steadily transmission efficiency height, long service life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further explanation.
Fig. 1 is a structural representation of the present invention.
The specific embodiment
In Fig. 1, hydraulic pressure ejector of the present invention, comprise hydraulic jack 1, the liftout carriage 2 that one end is installed on the hydraulic jack seat, the other end is installed in press bench base bottom, the ejector beam 3 that upwards drives by hydraulic cylinder piston rod, be installed in the table base bottom, be used for the following fairlead 4 that ejector beam leads, be installed in table base top, be used for the last fairlead 5 that ejector beam leads.
