Abstract
The utility model discloses a quick resetting means of hydro -cylinder, including moving beam, reach the big hydro -cylinder of a process with the moving beam mid -mounting, and set up in the big hydro -cylinder both sides of process, and the little hydro -cylinder of two return strokes with the moving beam installation, reach two four way solenoid valve that are connected with big hydro -cylinder of process and the little hydro -cylinder of return stroke, reach two three solenoid valve with the big hydro -cylinder separate connection of process. The utility model discloses a quick resetting means of hydro -cylinder can satisfy the requirement of opening speed 2000mmmin, and the quick oil drain in the big left chamber of hydro -cylinder mainly is the resistance that reduces the return stroke, left chamber of in addition little hydro -cylinder and the oil absorption in hydro -cylinder right side chamber greatly, and its effect keeps the lubrication in the jar and plays the effect that cushions.
Description
Technical field
The utility model relates to a kind of three cylinder control systems, is specifically related to a kind of oil cylinder Quick reset device, belongs to cylinder control system technical field.
Background technique
In horizontal tensile testing machine, oil cylinder is to provide the first-selection of power, and oil cylinder process is as tension test power, and its schedule speed is generally 20mm/min ~ 100mm/min, and oil cylinder backhaul general speed is 150mm/min to 250mm/min; In prior art, double pump system is usually adopted to go to realize this requirement; Process list pump work, backhaul double pump also connects work; And in practical application, in order to raise the efficiency, needing opening speed will reach 2000mm/min, the flow of oil pump is 10 times of our double pump flow, and it adopts the more difficult realization of existing cylinder system, or cost is very high.
Model utility content
(1) technical problem that will solve
For solving the problem, the utility model proposes a kind of oil cylinder Quick reset device, adopting three cylinder control systems, large tank is as process power, and two small oil tanks, as backhaul power, can meet opening speed 2000mm/min requirement.
(2) technological scheme
Oil cylinder Quick reset device of the present utility model, comprises dynamic crossbeam, and with dynamic crossbeam in the middle part of the process large tank installed; And be arranged at process large tank both sides; And the two backhaul small oil tanks installed with dynamic crossbeam; And two position four-way solenoid valves to be connected with process large tank and backhaul small oil tank; And the two-bit triplet solenoid valve to be connected separately with process large tank.
Further, backhaul small oil tank process end described in two connects is a road; It is a road that backhaul small oil tank backhaul side described in two connects.
Further, described dynamic crossbeam is installed with process large tank piston and two backhaul small oil tank pistons respectively.
(3) beneficial effect
Compared with prior art, oil cylinder Quick reset device of the present utility model, opening speed 2000mm/min requirement can be met, draining the oil fast of the left chamber of large tank mainly reduces the resistance of backhaul, the oil suction in the left chamber of small oil tank and the right chamber of large tank in addition, its effect keeps the lubrication in cylinder and plays buffering.
Accompanying drawing explanation
Fig. 1 is integral installation structural representation of the present utility model.
Fig. 2 is oil passage connection structure schematic diagram of the present utility model.
Embodiment
Oil cylinder Quick reset device as depicted in figs. 1 and 2, comprises dynamic crossbeam 1, and with dynamic crossbeam in the middle part of the process large tank 2 installed; And be arranged at process large tank both sides; And the two backhaul small oil tanks 3 installed with dynamic crossbeam; And two position four-way solenoid valves 4 to be connected with process large tank and backhaul small oil tank; And the two-bit triplet solenoid valve 5 to be connected separately with process large tank.
It is a road that backhaul small oil tank process end a, c described in two connect; It is a road that backhaul small oil tank backhaul side b, d described in two connect.
Described dynamic crossbeam 1 is installed with process large tank 2 piston and two backhaul small oil tank 3 pistons respectively.
During work, when two position four-way solenoid valves and two-bit triplet solenoid valves, two-bit triplet solenoid valve will drain the oil oil circuit disconnect, hydraulic oil is communicated with the left chamber of large tank by two position four-way solenoid valves, carry out tension test, at this moment two small oil tank pistons are drawn out, and the two right chambeies of small oil tank are in oil extraction state (the right chamber of large tank is also in oil extraction state); Left chamber place goes out oil suction state, after off-test, two solenoid valve power-off, two-bit triplet solenoid valve is in state of draining the oil fast, two position four-way solenoid valves are in small oil tank right chamber oil-feed, and because flow system flow is constant, and two small oil tank piston areas are far smaller than large tank piston area, so can realize quick return, its speed is than relevant with size piston area.
Embodiment recited above is described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that related domain ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
Claims (3)
1. an oil cylinder Quick reset device, is characterized in that: comprise dynamic crossbeam, and with dynamic crossbeam in the middle part of the process large tank installed; And be arranged at process large tank both sides; And the two backhaul small oil tanks installed with dynamic crossbeam; And two position four-way solenoid valves to be connected with process large tank and backhaul small oil tank; And the two-bit triplet solenoid valve to be connected separately with process large tank.
