Description
Technical field
The invention belongs to metal pipe material plasticity cold working field, it is related to a kind of space pipe fitting pane bending apparatus.
Background technology
In existing literature data, a kind of bending forming mechanism of spatial complex pipe fitting, its structural principle such as Fig. 7 institutes be present
Show, be mainly made up of forward block 1, stent 2 (being connected with frame), annular curved mould 3, pipe is crossed in stent and bending
Mould, bending die arbitrarily can be moved and rotated in xOy planes, realize the bending forming of different directions, at the same time, forward block pushes away
Dynamic pipe passes through the region between bending die and stent, final formingspace complex pipes.Generally, forward block also can be to pipe
Apply moment of torsion, to change the plane of bending during shaping or realize obstacle function.
Actuation means are mainly used in manipulating annular curved mould by regulation requirement campaign, realize the sky with complex appearance structure
Between pipe fitting shape.In existing literature, German Nuo Yi companies combine Japanese Nissin companies and develop a kind of free bend pipe
System, bending die is connected with stent by ball bowl structure, and under the cooperation of propulsive mechanism, actuation means manipulation bending die is lived
The bending forming of different shape pipe fitting is realized in a move in plane perpendicular to pipe axis in moved end.In the operating-controlling mechanism
In, because bending die die orifice axis points to the centre of sphere of ball bowl structure all the time, bending die die orifice plane and tubing axis can not be ensured
Vertically, the thrust and tube surfaces cut on forward block are added to a certain extent.United States Patent (USP) provide it is a kind of with six oneself
By the pipe bending mechanism of degree manipulator control, manipulator manipulation bending die deflects relative to stent, realizes arbitrary shape pipe
The bending forming of part.The device is flexible strong, can ensure that bending die die orifice plane is vertical with tubing axis, but needs to control simultaneously
Six-freedom degree, technological parameter decision-making difficulty are higher.
