Abstract
The multiple cylinder sequential action hydraulic loop for ten thousand ton hydraulic press includes two-position three way high speed solenoid valve and conic valve. Each oil cylinder has first stage control comprising 2 conic valves and 1 two-position three way high speed solenoid valve, the conic valves act as the main control valves and the high speed solenoid valve as the fore running valve. All the oil cylinders are connected in parallel, and 4 conic valves and 2 two-position three way high speed solenoid valves constitute the second stage or central control. The present invention has obvious reduced number of conic valves and high speed solenoid valves, and thus raised reliability and operation performance of the hydraulic loop.
Description
Technical field
The present invention relates to a kind of ton water hydraulic press that is used for material pressure processing, particularly relate to multiple cylinder sequential active hydraulic loop for ten thousand ton hydraulic press.
Background technology
The ton water hydraulic press control system will be controlled a plurality of hydraulic cylinder sequentially-operatings, traditional hydraulic circuit adopts the direct control mode of one-level, as shown in Figure 1, each hydraulic cylinder needs 4 cone valves and 2 high-speed switch electromagnetic valves, along with the increase of hydraulic cylinder quantity, required cone valve and high-speed switch electromagnetic valve quantity sharply increase, and cause the hydraulic circuit cost to increase, reliability reduces, and navigability descends.
Summary of the invention
In order to reduce the quantity of required cone valve of hydraulic circuit and high-speed switch electromagnetic valve, improve the reliability and the navigability of hydraulic system, the present invention provides a kind of employing secondary control mode multiple cylinder sequential active hydraulic loop for ten thousand ton hydraulic press according to the logical order of multi-cylinder sequentially-operating.
The technical solution adopted for the present invention to solve the technical problems is:
Multiple cylinder sequential active hydraulic loop for ten thousand ton hydraulic press, mainly comprise the two-position three way high-speed switch electromagnetic valve, cone valve, wherein each oil cylinder constitutes one-level control by 2 cone valves and 1 two-position three way high-speed switch electromagnetic valve control, wherein cone valve is as main control valve, high-speed switch electromagnetic valve is as pilot valve, and all oil cylinders that will control all are connected in parallel, and adopts 4 cone valve (V1, V2, V3, V4) (D1 D2) constitutes secondary control and carries out centralized Control with 2 two-position three way high-speed switch electromagnetic valves.By control D1, D2 and the action that just can control corresponding oil cylinder in requisition for the pilot valve of control oil cylinder.When certain oil cylinder carried out motion control, all the other oil cylinders were in locking state.
Described multi-cylinder sequentially-operating hydraulic circuit adopts the action of 2 cone valves and an oil cylinder of 1 two-position three way high-speed switch electromagnetic valve control.
Described multi-cylinder sequentially-operating hydraulic circuit can be controlled a plurality of hydraulic cylinders that the sequentially-operating logic is arranged.
Described multi-cylinder sequentially-operating hydraulic circuit, a plurality of hydraulic cylinders are in parallel, during one of them motion, all the other oil cylinders are in locking state.
Described multi-cylinder sequentially-operating hydraulic circuit, and 4 cone valves of employing (V1, V2, V3, V4) (D1 D2) constitutes secondary control centralized Control is carried out in the action of a plurality of oil cylinders with 2 two-position three way high-speed switch electromagnetic valves.
Described multi-cylinder sequentially-operating hydraulic circuit, the oil cylinder number of control is unrestricted, can be that N (N is the natural number greater than 2) is individual.
Utilize the present invention can significantly reduce the quantity of multiple cylinder sequential active hydraulic loop for ten thousand ton hydraulic press cone valve and high-speed switch electromagnetic valve, improve the reliability and the navigability of hydraulic circuit.
Description of drawings
Fig. 1: one-level control multi-cylinder sequentially-operating hydraulic circuit;
Fig. 2: secondary control multi-cylinder sequentially-operating hydraulic circuit of the present invention.
The specific embodiment
Multiple cylinder sequential active hydraulic loop for ten thousand ton hydraulic press as shown in Figure 2, mainly comprises two-position three way high-speed switch electromagnetic valve 1, cone valve 2 will be realized moving to right of oil cylinder G1, and the remaining fluid cylinder pressure is locked simultaneously, the action of high-speed switch electromagnetic valve is as follows: D1 and D3 get electric, all the other high-speed switch electromagnetic valve dead electricity; Realize moving to left of G1, the action of high-speed switch electromagnetic valve is as follows: D2 and D3 get electric, all the other high-speed switch electromagnetic valve dead electricity; When the D1 dead electricity, G1 is in locking state, and when D1 gets electricly, during all the other high-speed switch electromagnetic valve dead electricity, G1 is in quick condition.The action of all the other cylinders similarly.
