Abstract
The invention discloses a four-column hydraulic press and belongs to the field of metal forming machinery. The four-column hydraulic press comprises a machine base, stand columns, an upper beam, a movable beam and hydraulic cylinders, wherein the stand columns are fixedly installed on the machine base, the upper beam is fixedly installed on the top portions of the stand columns, the movable beam is installed on the stand columns in a sleeved mode, the hydraulic cylinders are fixedly installed on the upper beam, an output rod of each hydraulic cylinder is connected with the movable beam to drive the movable beam to move vertically along the stand columns, the hydraulic cylinders are connected with a plunger pump which is connected with a hydraulic control unit, and multiple pressure sensors are arranged on the machine base and are connected with the hydraulic control unit. According to the four-column hydraulic press, pressure information of the hydraulic press can be fed back to the hydraulic control unit, the hydraulic control unit regulates the pressure of the hydraulic cylinders quickly according to forming technological parameters, so that the pressure during the whole hydraulic process is controlled more accurately, and requirements of different technologies are met; the number of the pressure sensors is four, the four pressure sensors are arranged on four corners of the machine base, and pressure signals obtained through measurement are more accurate.
Description
?
Technical field
The present invention relates to a kind of hydraulic press, is specifically a kind of four-column hydraulic press, belongs to metal forming machinery field.
Background technology
Four-column hydraulic press is a kind of plant equipment of utilizing the static pressure of oil pump conveying liquid force feed to come the goods such as processing metal, plastics, rubber, timber, powder.It is usually used in pressing process and block pressing forming process, as forging and stamping, punching press, cold-extruded, alignment, bending, flange, process of sheet drawing, powder metallurgy, press-fit etc.The middle four-column hydraulic press of prior art is realized transmission by the static pressure of liquid pump conveying liquid force feed, but cannot hydraulic press pressure accurately be grasped and be controlled in practical work process, affects hydraulic press compacting efficiency and quality.
Summary of the invention
Technical problem to be solved by this invention is to overcome prior art defect, and providing a kind of can carry out to hydraulic pressure the four-column hydraulic press of accurately controlling in time.
In order to solve the problems of the technologies described above, four-column hydraulic press provided by the invention, comprise support, column, entablature, moved cross beam and hydraulic jack, described column is packed in support, described column top is fixedly mounted with entablature, described moved cross beam is sleeved on column, described hydraulic jack is packed on entablature, the take-off lever of described hydraulic jack is connected with moved cross beam, drive moved cross beam to move up and down along column, described hydraulic jack connects plunger displacement pump, described plunger displacement pump connects hydraulic control unit, it is characterized in that: described support is provided with several pressure sensors, pressure sensor is connected with hydraulic control unit.
As improvement, described pressure sensor is 4, is separately positioned on 4 angles of support.
As improvement, described hydraulic jack is 2, is set up in parallel on entablature.
Beneficial effect of the present invention is: (1), the present invention by being provided with pressure sensor on support, in time the pressure information of hydraulic press is fed back to hydraulic control unit, hydraulic control unit is adjusted the pressure of hydraulic jack fast according to molding technique parameter, use the pressure control of whole hydraulic pressure process more accurate, meet the demand of different process; (2), pressure sensor is 4, is separately positioned on 4 angles of support, makes the pressure signal that measures more accurate; (2), hydraulic jack is 2, is set up in parallel on entablature, ensured that moved cross beam pressure is more even.
