Description
Technical field
The utility model relates to the extrusion forming of bend pipe tools more particularly to a kind of rotary elbow pipe piece forming machines.
Background technique
Pipeline for fluid conveying generally includes pipe and connects the pipe fitting (also referred to as pipe fitting) of pipe.Traditional pipe
The connection of part and pipe is usually threadedly coupled to realize, and generally requires the materials such as cooperation unsintered tape to prevent from leaking, and makees
Industry inefficiency.
Had already appeared the compression joint type pipe-line system using compression joint type interconnection technique comprising: tubing, compression joint type pipe fitting,
Crimping tool three parts.The sealing tongue of compression joint type pipe fitting end is provided with special rubber seal, and when installation inserts steel pipe
Enter bellmouth pipe fitting to positioning step position, carries out circumference extruding with position of the dedicated crimping tool to sealing tongue.Rubber is close
Seal seals after being squeezed, and contraction distortion plays positioning fixed function while crimping position pipe fitting and tubing, to have
Realize to effect the connection of pipeline.
Extrusion forming process can be used in compression joint type pipe fitting, generally includes: flaring process, tack process, extrusion forming work
Sequence.

Raw material, which first passes around, to be cut blanking and forms straight pipe.Straight pipe forms bend loss raw material after bending, and Fig. 1 a shows this
The bend loss raw material of sample.Then expanding operation is carried out to above-mentioned bend loss raw material, i.e., it will be curved using flaring extrusion die head
The section diameter at pipeline section both ends increases, until the diameter needed for obtaining.Workpiece after flaring is as shown in Figure 1 b.Due to expanding
Deformation will lead to variation of the workpiece in length, therefore the Workpiece length after being flared does not meet required length requirement usually.
Therefore it needs accurately to be processed (for example, using turnery processing) to the length of the workpiece both ends part after flaring, i.e., tack adds
Work operation, thus the length dimension needed for obtaining.Workpiece after tack operation is as illustrated in figure 1 c.After finally needing to operate tack
Workpiece carry out extrusion forming operation and so that the both ends part of workpiece be made to form final shape especially form required ring
Shape groove (such as, it may include seal groove, annular groove etc.) structure.After extrusion forming operation, workpiece is formed as final pipe
Part product, the bend pipe tools product are as shown in Figure 1 d.
Above-mentioned compression joint type formation of tubes technique at least has the following disadvantages: to be circulated between different processes due to workpiece, is needed
It to be repeatedly loaded, cause working efficiency low.Different stations needs different personnel to operate, and leads to human cost height.Due to
Workpiece circulates between different molds, is unfavorable for being accurately positioned, and product size precision is not easy to guarantee, causes yield rate low, and
Increase die cost.
