Abstract

The utility model discloses an oil circuit structure realizing reverse differential motion of an oil cylinder by additionally arranging oil storage cylinders. The oil circuit structure includes oil circuit structures and a reverse differential motion control valve, and is characterized in that two or more oil circuit structures with the total cross sections less than the actual cross section of the basic oil cylinder are additionally arranged on the two sides of the basic oil cylinder; and a reverse differential motion control valve is additionally arranged on the basic oil circuit, so as to control the differential oil from the oil storage cylinders to go into the left chamber of the basic oil cylinder, and enable the reverse differential motion of the basic oil cylinder to pull the load at a high speed.

Description

A kind of usefulness is set up the oil channel structures that oil storage cylinder is realized the oil cylinder reversing differential
Technical field
The utility model relates to the basic oil cylinder of all kinds of hydraulic machineries such as being used for injection machine, die casting machine, realizes reverse differential oil channel structures.
Background technique
Present all hydraulic machinery all is the oil channel structures that adopts a basic oil cylinder and a basic control valve; The reversing differential oil storage cylinder all is not set; Can only realize that forward is differential so promote load; Can not realize reverse differentially, cause the speed of the reverse pulling load movement of present hydraulic machinery slow, the disadvantage that energy consumption is big.
The model utility content
To the defective that existing technology exists, the purpose of the utility model is to provide a kind of oil channel structures that oil storage cylinder is realized the reverse differential pulling load of basic oil cylinder of setting up.
Above-mentioned purpose realizes through following technological scheme:
A kind of usefulness is set up the oil channel structures that oil storage cylinder is realized the oil cylinder reversing differential; Include oil storage cylinder and reversing differential control valve; It is characterized in that: set up two or two oil storage cylinders that above sectional area sums are amassed less than basic oil cylinder actual cross-section in the both sides of basic oil cylinder; And in basic oil circuit, set up a reversing differential control valve, the differential oil of controlling oil storage cylinder with this valve gets into chamber, a basic oil cylinder left side, thereby realizes that basic oil cylinder reversing differential spurs load at a high speed.
The advantage of this oil channel structures: can be widely used in the differential action of die sinking and the lathe that oil pressure is used as power of the folding mould oil cylinder of injection machine, die casting machine, thereby can improve the speed and the effect of saving energy consumption of all kinds of oil pressure lathes greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of usefulness is set up the oil channel structures that oil storage cylinder is realized the oil cylinder reversing differential, includes basic oil cylinder 1 and basic control valve 2, and other has additional two oil storage cylinders 7 and reversing differential valve 3 realizes sending load oil cylinder reversing differential.
During work; During (backward) pulling load 6 to the right of basis oil cylinder 1, electromagnet D1, D4 energising, the P chamber of basic control valve 2 communicates with the A chamber; The P1 chamber of reversing differential valve 3 communicates with the B1 chamber; Pressure fuel pump oil moves to right to the left chamber 4 pulling loads 6 of basic oil cylinder 1 from the P chamber of basic control valve 2 to the A chamber again, and under load 6 moved to right the effect of power, the differential oily 8 B1 chambeies through reversing differential valves 3 of two oil storage cylinders 7 got into the P1 chambeies simultaneously; Also get into the left chamber 4 of basic oil cylinder 1 simultaneously, thereby realize that basic oil cylinder 1 reversing differential spurs load 6 fast.
