Summary of the invention
The purpose of this invention is to provide a kind of when bend pipe is worked, thereby pipe fitting can the demoulding, doing to vert motion can be in order to the bending die device in the full-automatic numerical-control hydraulic bending machine of crooked coil pipe.
For achieving the above object, the present invention has adopted following technical scheme.
Bending die device in the full-automatic numerical-control hydraulic bending machine, comprise: the wheel mould, be characterized in: in the wheel mould, be provided with inner chamber, be provided with piston in inner chamber, piston is separated into two not connected left inside chambeies and right inside chamber by inner chamber, piston is connected with piston rod thread, cylinder cap is fixed on the wheel mould, the cylinder cap seal cover is pressed on inner chamber, piston rod is movable to be fixedly connected with upper piece through after cylinder cap, between piston rod and cylinder cap mutually sealing contact, left inside chamber communicates with the first through hole on the wheel mould, right inside chamber communicates with the second through hole on cylinder cap, be fixed with the dovetails matched with upper piece on the wheel mould, on under the promotion of piston rod, piece can slide along dovetails, also be installed with lower piece on the wheel mould, lower piece is positioned at the below of piece, and with can clamp pipe fitting after upper piece coordinates.
Further, the bending die device in aforesaid full-automatic numerical-control hydraulic bending machine, wherein: the lower end at the wheel mould is provided with in order to bending pipe arm, mutually to locate fixing short mandrel.
Further, the bending die device in aforesaid full-automatic numerical-control hydraulic bending machine, wherein: between dovetails and upper piece, be provided with the gag in order to adjusting play.
Beneficial effect of the present invention: bend pipe when work, by built-in oil cylinder, drive piece to move back and forth, can clamp pipe fitting like this, can make again pipe fitting carry out the demoulding, the also do motion of verting, thereby can be suitable for crooked coil pipe.
