Abstract
The invention discloses a linkage telescopic valve applied to a rebar forming machine bending mechanism. The linkage telescopic valve applied to the rebar forming machine bending mechanism comprises a valve body connected with an oil cylinder oil channel and a telescopic valve pin installed in the valve body. The telescopic valve is in a linkage control by means of the oil cylinder oil channel, so that the telescopic valve can extend out the telescopic valve pin before an oil cylinder moves and retract back to the telescopic valve pin automatically after the oil cylinder moves. The linkage process does not need to be controlled by electronic equipment or watched and operated manually, so that the effect of structure simplifying and labor saving is achieved. Meanwhile, due to the fact that the linkage telescopic valve is arranged in the oil channel, the linkage telescopic valve can move by means the oil pressure of the oil cylinder, so that other powers do not need to be provided and cost is saved.
