Fine adjustment device for stroke of hydraulic oil press

Abstract

The invention provides a fine adjustment device for stroke of a hydraulic oil press. The fine adjustment device comprises a top plate, upright columns, a lower plate, an upper slider, a first slide groove, a second slide groove, a proximity switch, a limiting stopper and a micrometer. One end of each upright column is connected to the lower end of the top plate, the other end of each upright column is connected to the upper end of the lower plate; the upper slider is positioned below the top plate, through holes are formed in the upper slider, the upright columns penetrate the through holes, and the upper slider slides along the upright columns up and down via the through holes; the first slide groove and the second slide grooves are formed in positions between the top plate and the lower plate; the proximity switch is arranged on the first slide groove and moves along the first slide groove up and down; the limiting stopper is fixedly arranged on the second slide groove; the micrometer is mounted on the limiting stopper and is used for finely adjusting the limiting stopper up and down. The fine adjustment device has the advantages that adjustment and control on the stroke of the hydraulic oil press can be displayed via readable data of the micrometer, accordingly, accurate adjustment and control effects can be realized, debugging frequency can be effectively reduced in forging procedures, a die trial rejection rate can be reduced, the cost can be decreased, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the field of presses, in particular to a stroke fine adjustment device for hydraulic presses. Background technique [0002] The hydraulic press is a kind of special hydraulic oil as the working medium and the hydraulic pump as the power source. The force of the pump makes the hydraulic oil enter the cylinder / piston through the hydraulic pipeline, and then there are several sets of seals in the cylinder / piston that cooperate with each other. , The seals in different positions are different, but they all play a role in sealing, so that the hydraulic oil cannot leak. Finally, the hydraulic oil is circulated in the oil tank through the check valve, and the oil cylinder / piston is circulated to do work to complete certain mechanical actions as a kind of productivity machine. When adjusting the mold clamping height h (the mold clamping height refers to the distance between the upper slider and the lower plate), it is used to adjust t...

Problems solved by technology

When adjusting the mold clamping height h (the mold clamping height refers to the distance between the upper slider and the lower plate), it is used to adjust the extrusion stroke of the punch. To achieve a certain mold clamping height, you need to manually adjust the asymptotic switch to determine the slide There is no accurate digital concept for on-site manual adjustment. All relying on this experience and feel, it is impossible to achieve accurate positioning of the slider, which affects the quality of the product and produces more debugging and scrapping.
