Abstract
The utility model provides a preparing press sliding block balance hydraulic system which does not have the defects of being easy to be eroded and great noise in the prior art. The technical proposal is that the preparing press sliding block equilibrium hydraulic system comprises a hydraulic pump, an oil tank, a balance-cylinder, an accumulator component, a direct drive overflow valve, an one-way valve, a pressure relay, and a pressure gauge. The hydraulic pump is connected with the oil tank. The hydraulic pump is connected with the balance-cylinder through the one-way valve and a hydraulic pipeline. The accumulator component is connected with the hydraulic pipeline through a middle hydraulic pipeline. The pressure relay is connected with the middle hydraulic pipeline. The pressure gauge is connected with the hydraulic pipeline. The direct drive overflow valve is connected with the middle hydraulic pipeline. The overflow port of the direct drive overflow valve is connected with the oil tank.
Description
Technical field
The utility model relates to the dead-weight balanced of bedding-in press ram and mould, belongs to proprietary system.
Background technique
At present, existing conventional machinery press machine since the deadweight of slide block and mould by air pressure balance, the main power source of balance portion is an air compressor, executive component is a cylinder, the pressure of general gas can only reach 0.7Mpa, hydro-cushion pressure can reach 10Mpa, comparatively speaking, needs very big cylinder; From environmental angle, the cylinder noise is very big, and subsidiary moisture in the gas, and pipeline corrodes easily.
Summary of the invention
The purpose of this utility model provides a kind of bedding-in press ram balanced hydraulic system, has the big defective of the easy burn into noise of pipeline to avoid existing pressure system.
The purpose of this utility model is achieved by the following technical solution: bedding-in press ram balanced hydraulic system, be made up of oil hydraulic pump, fuel tank, compensating cylinder, accumulator assembly, direct-acting overflow valve, one-way valve, pressure relay, pressure gauge; Oil hydraulic pump is connected on the fuel tank, and oil hydraulic pump is connected with compensating cylinder by one-way valve, hydraulic tubing, and the accumulator assembly is connected with hydraulic tubing by middle hydraulic tubing, and on the hydraulic tubing, pressure gauge was connected on the hydraulic tubing in the middle of pressure relay was connected; On the hydraulic tubing, the flow-off of direct-acting overflow valve was connected to fuel tank in the middle of direct-acting overflow valve was connected.
Pressure relay is used for balance is carried out in the deadweight of slide block and mould.Slide block and mould balance oil circuit in running, keep the compensating cylinder internal pressure near constant by accumulator, and by pressure relay setting high low pressure, when pressure is lower than low pressure, the starting electrical machinery repairing, when pressure was higher than high pressure, motor cut out, the accumulator pressurize.
The utility model patent is owing to whole employing is that hydraulic control structure and the air-pressure balancing device of conventional machinery machine use now relatively have following characteristics:
(1), at work, the accumulator pressurize, when having only energy storage pressure to be lower than pressure relay low pressure, just the starting electrical machinery repairing can reach energy-conservation effect like this.
(2), volume is little, installs easily, and is simple to operate.
(3), working medium is antiwear hydraulic oil, noise free in the course of the work, selflubricating does not have corrosion.
(4), power source is the driven by motor oil hydraulic pump, the output high pressure oil can have a power unit of one's own, uses simple, easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
In conjunction with shown in Figure 1, it is as follows to describe bedding-in press ram balanced hydraulic system: oil hydraulic pump 7 is connected on the fuel tank 8, oil hydraulic pump 7 is connected with compensating cylinder 4 by one-way valve 1, hydraulic tubing 10, accumulator assembly 3 is connected with hydraulic tubing 10 by middle hydraulic tubing 9, on the hydraulic tubing, pressure gauge 6 was connected on the hydraulic tubing in the middle of pressure relay 5 was connected; On the hydraulic tubing 9, the flow-off of direct-acting overflow valve 2 was connected to fuel tank in the middle of direct-acting overflow valve 2 was connected.
During work, regulate the high low pressure of pressure relay 5 in the system earlier.
In system's running, when compensating cylinder 4 pressure are lower than pressure relay 5 low pressure setting values, the starting electrical machinery repairing, high pressure oil enters accumulator assembly 3 and compensating cylinder 4 by one-way valve 1 earlier, when pressure is higher than the high pressure setting value of pressure relay 5, motor stops operating, (because the effect of one-way valve, fluid can only unidirectionally enter) accumulator pressurize.
2 safety effects of direct-acting overflow valve, when oil hydraulic cylinder was descending, energy storage pressure was too high, and direct-acting overflow valve 2 is opened, and reduces pressure, protection oil cylinder and accumulator.Go wrong high pressure can not stop the time at pressure relay, and direct-acting overflow valve 2 also can play safety effect.
The pressure of compensating cylinder can be regulated by the setting of direct-acting overflow valve 2 and pressure relay 5 high low pressures, and press machine table 6 is used for showing compensating cylinder 4 instantaneous pressures.
Claims (1)
1, bedding-in press ram balanced hydraulic system is characterized in that: be made up of oil hydraulic pump, fuel tank, compensating cylinder, accumulator assembly, direct-acting overflow valve, one-way valve, pressure relay, pressure gauge; Oil hydraulic pump is connected on the fuel tank, and oil hydraulic pump is connected with compensating cylinder by one-way valve, hydraulic tubing, and the accumulator assembly is connected with hydraulic tubing by middle hydraulic tubing, and on the hydraulic tubing, pressure gauge was connected on the hydraulic tubing in the middle of pressure relay was connected; On the hydraulic tubing, the flow-off of direct-acting overflow valve was connected to fuel tank in the middle of direct-acting overflow valve was connected.
