Chinese patent application prospectus ZL200710302501 discloses a kind of head of bending machine, this head is that a kind of fuselage that is not subjected to pins down, reduce whole bending machine manufacturing cost, the pipe bender head that operates steadily, comprise: headstock, be movably set with the main shaft and the driving shaft that are parallel to each other in the headstock, be provided with head sprocket on the main shaft, be provided with the drive sprocket that matches with head sprocket on the driving shaft, head sprocket links to each other with drive sprocket by driving chain, also be provided with driven wheel on the described driving shaft, also be provided with the master cylinder and the guiding mechanism that match with driven wheel on the described headstock, guiding mechanism is positioned at the below of driven wheel, between guiding mechanism and driven wheel, be provided with the tooth bar that is meshed with driven wheel, the bottom of tooth bar is shelved on the guiding mechanism, and an end of tooth bar and the piston rod of master cylinder are set together.This head is mainly used in the full-automatic multi-layer mould bending machine.
Chinese patent application 200710109091.2 prospectus disclose a kind of bending machine, this bending machine is provided with the feed mechanism of carrying pipe fitting in support one end, pipe fitting is through carrying pan feeding in swan neck system, and the swan neck system correspondence is mounted on a mechanism that can make its vertical upper and lower displacement, and this length travel mechanism correspondence is incorporated on the substrate with horizontal left and right displacement mechanism, and substrate be incorporated on the support set have can the mechanism of 360 degree rotations on, and this rotating mechanism can pass through for the material pipe of feeding mechanism, carries out the free angle bend pipe with feeding to swan neck system; By the said structure setting, make this bending machine have the circumference radial rotary and cooperate the in length and breadth motion that turns to of axial three-dimensional space of X, Y, allow this bending machine can apply the workpiece of arbitrary curvature.
In the prior art, be the Anti-wrinkling board that the Chinese invention patent " bending machine special-purpose split type Anti-wrinkling board " of ZL200920094258.7 discloses a kind of bending machine such as the patent No., this Anti-wrinkling board is the special-purpose split type Anti-wrinkling board of a kind of bending machine, it is characterized in that: the Anti-wrinkling board frame body is No. 45 steel, Anti-wrinkling board is copper, cooperate with holotype between wrinkle resistant grillage and the Anti-wrinkling board, Anti-wrinkling board is provided with locating slot, is connected on the wrinkle resistant grillage with the bolted connection.Its split type Anti-wrinkling board only need more renew the copper sheathing Anti-wrinkling board and just can continue to use after using wearing and tearing, can reduce the manufacturing cost of Anti-wrinkling board, has reduced it and has changed the cost of part.
And for example the patent No. is the flexible anti-corrugating-plate device that the Chinese invention patent " flexible anti-corrugating-plate device of bending machine " of ZL99201541.3 discloses a kind of bending machine, to be provided with a rotating shaft at a bending machine device, one grip slipper, one guide wheel mould, one Anti-wrinkling board and a positioning seat, and Anti-wrinkling board is installed in one and revolves an edition end face, before the workpiece feeding, rotating plate is subjected to the driving of a driving element can drive Anti-wrinkling board swing outwardly, make workpiece end try one's best convergence grip slipper and guide wheel mould, take this to reach and save tailing and save the required processing cost of sawing tailing.
But, the pipe fitting pusher of above-mentioned patent bending machine, complex structure is made the assembly trouble.And, usually bending machine adds man-hour carrying out bend pipe, in order to guarantee the circularity of workpiece, can plug plug in pipe fitting, adopt the clout pusher of above-mentioned patent bending machine, these devices can produce with plug interferes, so that its stroke is not enough to the clout in the pipe fitting clamping device is released fully, if dwindle the plug radius for adapting to these devices, that just can't guarantee to process the circularity of pipe fitting, and pipe fitting is easy in the bend pipe process in bending place generation fold.Therefore, the pipe fitting pusher of above-mentioned patent bending machine still can't be realized taking full advantage of clout under the prerequisite that guarantees crudy.
In addition, the Anti-wrinkling board of bending machine in the above-mentioned patent does not reduce the friction between Anti-wrinkling board surface and the bend pipe pipe fitting, does not namely improve the wear problem of Anti-wrinkling board, therefore, is still waiting to do further improvement.
In addition, the head of bending machine in the above-mentioned patent needs to cooperate pipe end forming machine could realize enlarging, reducing, and the multiple tube end maching function such as pier nose, and can not carry out the curved disjunctor processing in the left and right sides, also can't switch fast station according to the needs of processing.
