Abstract
The utility model relates to a guard door pneumatic device of die casting machine, which comprises a mechanical part of the guard door and a pneumatic driving device, wherein, the pneumatic driving device is provided with a cylinder which is connected with the mechanical part of the guard door. Air source is communicated with the cylinder through a pipeline, and a main pneumatic reversing valve is connected to the pipeline between the air source and the cylinder. A gas outlet of the main pneumatic reversing valve is connected with a secondary pneumatic reversing valve through a pipeline, and an outlet of the secondary pneumatic reversing valve is also provided with a throttle valve. When started, the guard door can be stably ran, when ran to the end, the guard door can be stably stopped. The utility model has the advantages of reasonable and simple structure.
Description
Technical field
The utility model relate to a kind of die casting machine the door that protects, particularly a kind of die casting machine protect a pneumatic system.
Background technology
Protecting door is one of important components on the die casting machine, is the indispensable safety device of machine.On the medium-and-large-sized die casting machine to protect a volume heavy.In order to alleviate working strength of workers, adopt compressed air as power source mostly, with no parts of control such as pneumatic operated valves, control the magnetic cylinder, thereby drag the keying of protecting door.Its weak point is: the operation of protecting door is very not steady, is difficult to control exactly and regulate operating rate.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of pneumatic means that protects of the die casting machine that operates steadily.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of die casting machine protect a pneumatic means, it comprises mechanical part and the pneumatic actuating device that protects door, described pneumatic actuating device is provided with and protects the cylinder that a mechanical part joins, source of the gas is connected with cylinder by pipeline, on the pipeline between source of the gas and the cylinder, be connected with main air operated reversing valve, be characterized in: be connected with secondary air operated reversing valve in described main air operated reversing valve gas outlet by pipeline, choke valve also be housed in the outlet of secondary reversal valve.Drag at cylinder and to protect when opening and closing, main air operated reversing valve conversion is by the chamber air feed of source of the gas to cylinder, lose heart by the gas outlet of reversal valve in another chamber of cylinder, because the air operated reversing valve of gas outlet and the effect of choke valve slow down the speed of giving vent to anger by adjusting, then make the keying of protecting door steady.
The technical problems to be solved in the utility model can also be achieved through the following technical solutions, and two gas outlets of described main air operated reversing valve all are connected with secondary air operated reversing valve respectively, in the outlet of each secondary reversal valve choke valve are housed all.
The utility model compared with prior art, two gas outlets of main air operated reversing valve of protecting in the pneumatic system of door at die casting machine add secondary air operated reversing valve and choke valve, make that protecting door operates steadily when opening and closing, and when running to the end, can steadily stop.The utility model is simple and reasonable, and result of use is good.
Description of drawings
Accompanying drawing is the utility model pneumatic system sketch.
The specific embodiment
As shown in the figure, a kind of die casting machine protect a pneumatic means, it comprises mechanical part and the pneumatic actuating device that protects door, described pneumatic actuating device is provided with and protects the cylinder 3 that a mechanical part joins, source of the gas 2 is connected with cylinder 3 by pipeline, on the pipeline between source of the gas 1 and the cylinder 3, be connected with main air operated reversing valve 4, two gas outlets at described main air operated reversing valve 4, be connected with two secondary air operated reversing valves 1 by pipeline respectively, choke valve 5 also be housed in the outlet of each secondary reversal valve 1.
