For addressing the above problem, the utility model discloses a kind of special-shaped magnesium tube bending machine mandrel, it is characterized in that, comprising:
At least two spheroids and stone dead wire, described in each, on ball centre axle, have first through hole, described stone dead wire is chained together at least two described spheroids through described the first through hole, afterwards at a block of one end of described stone dead wire welding, the described stone dead wire other end welds another block through after mandrel adjusting sleeve, and described block is set to prevent that spheroid from dropping from described stone dead wire;
Mandrel adjusting sleeve, its be one end with the cylindrical shell of a bottom surface, described mandrel adjusting sleeve other end opening, described bottom center is provided with second through hole, described stone dead wire one end is through being welded and fixed by described block after described the second through hole.
Preferably, special-shaped magnesium tube bending machine also comprises with mandrel:
Mandrel connecting rod, it is shape round bar always, its front end is threaded, described mandrel rod rear end is fixedly attached on bending machine pedestal, on described mandrel adjusting sleeve openend madial wall, there is screw thread, described mandrel adjusting sleeve is connected to described mandrel connecting rod front end, and described mandrel connecting rod screw thread and described mandrel adjusting sleeve screw thread are intermeshing.
Preferably, the diameter of described spheroid and magnesium pipe interior diameter size adapt.
Preferably, the number of the above spheroid setting of described stone dead wire is adjusted according to the length of the central axis of magnesium pipe deformed area, is specially (length/magnesium pipe interior diameter of the central axis of described magnesium pipe deformed area)+1.
Preferably, the clearance distance between described spheroid is 0.5～1mm.
Preferably, the distance of described spheroid and mandrel adjusting sleeve front end face is 0.5～1mm.
Preferably, described in first of adjacent described mandrel adjusting sleeve, the opposite side top of spheroid and described bending machine distortion roller center line are tangent.
Preferably, described mandrel adjusting sleeve internal thread length is less than described mandrel length of connecting rod.
The beneficial effects of the utility model are that the setting of described stone dead wire makes the mandrel can be with the deformation process generation deformation of magnesium pipe deformed area, keep described spheroid to be distributed in all the time in magnesium pipe deformed area, guaranteed the phenomenon of flat pipe can not occur in magnesium pipe bending process, a block is welded in one end that described stone dead wire has been contacted after spheroid, and the described stone dead wire other end can prevent that through welding another block after mandrel adjusting sleeve spheroid from dropping from described stone dead wire; Mandrel connecting rod is generally regular length, and on mandrel connecting rod, the setting of sheathed described mandrel adjusting sleeve can make their entire length finely tune, thereby adapts to the needs of the distortion roller adjustment of different-diameter size.Mandrel adjusting sleeve can be for convenience detach, can change like this mandrel of different size.In a word, the utility model, simple in structure, easy to operate, make special-shaped magnesium pipe in BENDING PROCESS, not occur the phenomenon of flat pipe, and the replacing of described mandrel is convenient and swift, can be applicable to large-scale production.
Accompanying drawing explanation
Fig. 1 is special-shaped magnesium tube bending machine core shaft structure schematic diagram described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, to make those skilled in the art can implement according to this with reference to description word.
As shown in Figure 1, special-shaped magnesium tube bending machine described in the utility model comprises with core shaft structure:
At least two spheroids 2 and stone dead wire 3, described in each, on ball centre axle, have first through hole, described stone dead wire is chained together at least two described spheroids through described the first through hole, afterwards at a block 1 of one end of described stone dead wire welding, the described stone dead wire other end is through welding another block 4 after mandrel adjusting sleeve 7, and described block is set to prevent that spheroid from dropping from described stone dead wire; Mandrel adjusting sleeve 7; It is one end with a bottom surface cylindrical shell with the second through hole, described mandrel adjusting sleeve other end opening, is threaded in described mandrel adjusting sleeve front inner wall, described stone dead wire one end is through being welded and fixed by described block after described the second through hole.Mandrel connecting rod 6, it is shape round bar always, on its front end side, there is screw thread, described mandrel rod rear end is fixedly attached on bending machine pedestal, on described mandrel adjusting sleeve openend madial wall, there is screw thread, described mandrel adjusting sleeve is connected to described mandrel connecting rod front end, and described mandrel connecting rod screw thread and described mandrel adjusting sleeve screw thread are intermeshing.The number of the above spheroid setting of described stone dead wire is adjusted according to the length of the central axis of magnesium pipe 5 deformed areas 8, is specially (length/magnesium pipe interior diameter of the central axis of described magnesium pipe deformed area)+1.
