Description
Technical field
The utility model belongs to hydraulic transmission technology field.
Background technique
Forging hydraulic press is also called free-forging hydraulic, for completing various smith forging technique.Under about the pressure of hydraulic machine working cylinder, by upper and lower anvil and some simple general utility tools, steel ingot or blank is made at high temperature to produce moulding deformation, to obtain the forging of required form and size.High-pressure high-flow oil hydraulic pump conventional in forging hydraulic press has cam-type axial piston pump, angle type axial piston pump and radial plunger pump, wherein common with bent axis type axial piston pump.
Existing angle type axial piston pump is made up of transmission shaft, connecting rod, cylinder body, plunger, plane thrust plate, transmission shaft and rod hinge connection, plunger in connecting rod and cylinder body plunger cavity is hinged, plane thrust plate and cylinder body offset, in plunger cavity, hydraulic oil can flow in the extrusion chamber in plane thrust plate, and the hydraulic oil in plane thrust plate suction chamber can flow in plunger cavity.Cylinder body and transmission shaft are certain angle of inclination, when drive axis, cylinder body also rotates thereupon, and plane thrust plate maintains static, by changing the plunger length stretched in plunger cavity, plunger cavity volume is changed, thus complete oil suction and the force feed of plane thrust plate window.The shortcoming of technique scheme is: planar oil distributing dish and cylinder body strut need to be connected by rolling bearing, to ensure that cylinder body rotates relative to planar oil distributing dish, but in actual using process, the noise and vibration of rolling bearing is comparatively large, affects the use of plunger pump.On the other hand, planar oil distributing dish needs and cylinder bottom close contact, and mainly in order to ensure that plunger cavity communicates with the oil duct on planar oil distributing dish, but planar oil distributing dish can produce with the part of cylinder bottom except plunger cavity and rubs, cylinder body rotational velocity is reduced, affects the working efficiency of plunger pump.
Model utility content
The utility model be intended to provide a kind of rub little, rotate fast and that noise is little forging hydraulic press plunger pump.
Forging hydraulic press plunger pump in this programme, comprise the pump housing, this pump housing is provided with transmission shaft, the output face of transmission shaft is hinged with strut and some connecting rods, and connecting rod is centered around around strut, the piston hinge in connecting rod free end and cylinder body plunger cavity, strut is connected with oil distribution casing after running through the strut mounting hole at cylinder body center, be arranged with the shell fixing with the pump housing outside cylinder body, oil distribution casing is welded on this outer casing bottom, and the rat of this oil distribution casing forms the cambered surface for supporting cylinder base.
Beneficial effect: the oil distribution casing surface in the utility model is in cambered surface, relative motion surface between the bottom surface of cylinder body and oil distribution casing is with mating spherical surfaces, cylinder body is just connected with the cambered surface of oil distribution casing securely by the strut at center, swing because cylinder body can do spheroid around the strut at center, there is self-align effect; In addition, an oil distribution casing cambered surface high position and cylinder body plunger cavity close contact, oil distribution casing cambered surface low level does not contact with cylinder body, and the friction be subject to when cylinder body rotates is less, and rotation rotational velocity is high; Adopt strut and oil distribution casing cambered surface hinged, compare traditional plunger pump cylinder body and be connected by rolling bearing with strut, noise with vibrate less.
Further, described cylinder body axis and drive shaft axis are 25 ° of angles, and the stroke of plunger cavity inner carrier is longer, and whole plunger pump transmitting power is larger.
Further, the number of described connecting rod is 7, and corresponding plunger cavity number is also 7, exportable higher pumping force.
Further, the hinged place of described strut and transmission shaft output face is provided with shock-absorbing spring, reduces the vibration produced when cylinder body rotates.
Further, oil distribution casing has arc and not connected pumping cavity and go out oil pocket, pumping cavity is identical with the motion radius of curvature of the radius of curvature with plunger cavity that go out oil pocket, pumping cavity when plunger cavity moves and on oil distribution casing or go out oil pocket, realizes force feed or oil suction.
