Abstract
A kind of forcing press is the utility model is related to, concretely relates to a kind of air pipe line structure of press air cushion.It includes air tank, air cushion, the air tank exhaust outlet is connected with choke valve, throttling valve outlet is connected with Pneumatic controlling three-way valve, and the outlet of Pneumatic controlling three-way valve is respectively communicated with the upper cylinder air inlet and lower cylinder air inlet of air cushion, and upper cylinder exhaust outlet connects air tank with lower cylinder exhaust outlet by check valve.The utility model structure design advantages of simple, air inlet pipeline are provided with choke valve, and air inlet pipeline diameter is less than gas exhaust piping diameter, and air inflow is easy to control, and piston operates steadily, and exhaust is fast, and piston return is fast, and forcing press operating efficiency improves.
Description
Technical field
A kind of forcing press is the utility model is related to, concretely relates to a kind of air pipe line structure of press air cushion.
Background technology
The air inflow of existing press air cushion is uncontrollable, and air inlet is fast, unstable, causes piston fluctuation of service, and outlet is slow,
Efficiency is low.
The content of the invention
Therefore, the purpose of this utility model is to provide the press air cushion that a kind of air inflow is controllable, air inlet is slow, outlet is fast
Air pipe line structure.
What the purpose of this utility model was realized in.
A kind of air pipe line structure of press air cushion, including air tank, air cushion, the air tank exhaust outlet are connected with section
Flow valve, throttling valve outlet is connected with Pneumatic controlling three-way valve, the outlet of Pneumatic controlling three-way valve be respectively communicated with the upper cylinder air inlet of air cushion with
Lower cylinder air inlet, upper cylinder exhaust outlet and lower cylinder exhaust outlet connect air tank by check valve.
Above-mentioned technical proposal can be also made to the following further improve.
The upper cylinder, the air inlet of lower cylinder and exhaust ports are in same position.
The air cushion is two or more, and each air cushion upper cylinder, the air inlet of lower cylinder connect gas control threeway respectively
The outlet of valve, each air cushion upper cylinder, the exhaust outlet of lower cylinder connect with check valve jointly.
The utility model structure design advantages of simple, air inlet pipeline are provided with choke valve, and air inlet pipeline diameter is less than exhaust
Pipeline diameter, air inflow is easy to control, and piston operates steadily, and exhaust is fast, and piston return is fast, and forcing press operating efficiency improves.
Brief description of the drawings
Fig. 1 is the utility model piping arrangement.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Embodiment, with reference to accompanying drawing, a kind of air pipe line structure of press air cushion, including 1, two air cushion 2 of air tank, institute
State the exhaust outlet of air tank 1 and be connected with choke valve 3, the outlet of choke valve 3 is connected with Pneumatic controlling three-way valve 4, the outlet point of Pneumatic controlling three-way valve 4
Not Lian Tong two air cushions 2 the air inlet of upper cylinder 5 and the air inlet of lower cylinder 6, the exhaust outlet of upper cylinder 5 of two air cushions 2 and lower gas
The exhaust outlet of cylinder 6 connects air tank 1 commonly through check valve 7.Upper cylinder, the air inlet of lower cylinder and exhaust ports are in same position
Put.During inflation, the vent of air tank, air distinguishes air inlet upper cylinder and lower cylinder by choke valve, Pneumatic controlling three-way valve,
Because air pressure tank is more than Air Cushion Cylinder pressure, air can only enter cylinder, will not return to air tank by check valve.Exhaust
When, piston pushes, and the air in upper cylinder and lower cylinder is through check valve air inlet tank, and only a small amount of air is through Pneumatic controlling three-way valve
Return to air tank.
