Abstract
The utility model relates to a function test device of a press for simulating practical operating condition of the press. The function test device comprises an oil cylinder, a piston and a gas-liquid container, wherein the gas-liquid container is provided with a compressed air inlet, and an oil outlet of the gas-liquid container is communicated with an oil inlet of the oil cylinder through an oil pipeline; and the oil pipeline is provided with a one-way valve, one side of the one-way valve is provided with a bypass pipe connected with a bypass one-way valve in the oil pipeline, and the bypass pipeline is provided with a hydraulic pressure gauge and an overflow valve where an overflow pressure can be preset. The function test device is characterized in that the oil cylinder and the gas-liquid container are connected by the one-way valve, one side of the one-way valve is the bypass overflow valve, and gas source of the gas-liquid container is from the compressed air of the press. The function test device has the advantages that the compressed air of the press is used as the power source, so that extra air pump or oil pump is not required, and production cost is low; and hydraulic oil is driven by the compressed air to enter the oil cylinder with a high speed, rapid stamping test requirement of the press is satisfied, and test efficiency of the test device is improved.
Description
Technical field
The utility model relates to a kind of function detection device that simulates the pressing machine of pressing machine practical working situation.
Background technology
The function detection device of pressing machine of the prior art all is to establish power source by other, oil pressure oil-feed cylinder, drift by pressing machine hits piston again, again oil is squeezed into fuel tank by piston, this pick-up unit has two weak points, the one, oil flow speed is slower, can not satisfy the quick punching press test request of pressing machine.The 2nd, additional configuration motor and oil pump increase and detect cost.
The utility model content
The purpose of this utility model is to provide a kind of and realizes fast detecting, utilizes the existing pressurized air of tested pressing machine to do the device for testing functions of the pressing machine of power source simultaneously.
The purpose of this utility model is to realize like this.
A kind of device for testing functions of pressing machine, comprise oil cylinder, piston, gas-liquid jar, described gas-liquid jar is provided with compressed air inlet, the oil export of described gas-liquid jar is by oil pipe line and the conducting of oil cylinder oil-in, be provided with retaining valve in the oil pipe line, one side of retaining valve is provided with by-pass pipe, and by-pass pipe is connected in bypass retaining valve in the oil pipe line, is provided with hydralic pressure gauge and the surplus valve that can preestablish oil pressure relief in the bypass line.
Oil cylinder of the present utility model is connected by retaining valve with the gas-liquid jar, one side bypass of retaining valve has surplus valve, the source of the gas of gas-liquid jar comes from pressing machine pressurized air, because adopt the compressed air source of pressing machine, the utility model need not optional equipment air pump or oil pump, production cost is low, owing to adopt pressurized air to promote, it is fast that hydraulic oil enters the speed of oil cylinder, satisfies the quick punching press test request of pressing machine, improved the testing efficiency of proving installation.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model schematic diagram.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As depicted in figs. 1 and 2, a kind of device for testing functions of pressing machine, comprise piston 1, oil cylinder 2, gas-liquid jar 3, gas-liquid jar 3 is provided with compressed air inlet, inflow point is provided with pneumatic triple piece 4, stop valve 5 and safety valve 6, and the pressurized air that produces when tested pressing machine does work imports in the gas-liquid jar 3 by air in.Gas-liquid jar 3 is provided with oil export 7, and oil export 7 is provided with retaining valve 8 by oil pipe line and oil cylinder 2 oil-in conductings in the oil pipe line, and the air that enters the gas-liquid jar enters oil cylinder to the hydraulic oil pressure flow container of giving vent to anger through retaining valve, piston jack-up.At other its by-pass pipe of bypass that is provided with of retaining valve, by-pass pipe is connected in the oil pipe line, be provided with the hydralic pressure gauge 9 that shows oil pressure and the surplus valve 10 that can set oil pressure relief in the bypass line, when piston 1 is hit by the drift of pressing machine, compressed action pushes back the gas-liquid jar surpassing the hydraulic oil that preestablishes pressure through surplus valve downwards, is the pressure that hydralic pressure gauge shows according to formula: F=P*S(P, S is the piston base area) just can obtain the pressing machine stamping pressure, thus the performance of test pressure machine.
The embodiment of the above is preference of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.
