Therefore, it is necessary to a kind of swan neck system is provided, to overcome drawbacks described above.

Utility model content

The purpose of this utility model is to provide a kind of swan neck system, and technical problem to be solved is to cause swan neck system Step needed for reducing dismounting when bend pipe is taken out, work can not be dismantled while the loss of bending machine is reduced during bend pipe Part and to workpiece, other positions carry out bend pipe.

To achieve the above object, the utility model provides a kind of swan neck system, including：Support base, slide cylinder and Press rods, the support base is provided with rotation section and connecting portion, and the press rods include ejection cylinder, master mold and press rods Pipe sleeve, the slip cylinder drives the press rods to be moved along a straight line on the support base, and the master mold is fixed on described One end of cylinder is ejected, the rotation section is provided with the secondary mould and fixed dress being fixed on by housing pin on the rotation section Put.

Compared with prior art, the utility model fixes workpiece by adjustable fixing device, eliminates dismounting The fixing device could take out the operation of bend pipe, mould is avoided during curved workpieces and is damaged by the pulling force of workpiece Mould, in addition, can by it is described slip cylinder and the ejection cylinder reach fine setting crooked position purpose, also achieve without Dismounting workpiece is the function at flexible other positions.

It is preferred that the master mold is to set reeded round roller with the secondary mould.

It is preferred that the fixing device includes regulating tank and binding clasp, the regulating tank is provided with some fixing holes, described Binding clasp is fixed on the regulating tank by selecting suitable fixing hole, so that the fixed position of workpiece is adjustable.

It is preferred that the slip cylinder is fixed on the connecting portion and perpendicular to the press rods.

It is preferred that the rotation section is circular Rotary tray.

It is preferred that the secondary mould is removably connected with the rotation section.

It is preferred that the displacement for sliding cylinder can adjust with phase interworking with the advance distance of the ejection cylinder Close.

Specific embodiment

With reference now to Description of Drawings embodiment of the present utility model, the reference numerals being similar in accompanying drawing represent similar group Part.

Fig. 2 is refer to, is a kind of swan neck system 100 of the present utility model, included support base 20, slide cylinder 30, pressure Power bar 40 and workpiece 50.

The support base 20 is provided with rotation section 21 and connecting portion 23, and the rotation section 21 is circular Rotary tray, described Rotation section 21 is provided with secondary mould 212 and fixing device 213, and the fixing device 213 includes regulating tank 215 and binding clasp 216。

The secondary mould 212 to set reeded round roller and being removably connected with the rotation section 21, by institute State housing pin 219 to be fixed at the coaxial center surface of the rotation section 21, the slip cylinder 30 drives the press rods 40 slide on the connecting portion 23, and the regulating tank 215 is provided with fixing hole 217, the clamping in tubular construction and at surface Device 216 is fixed in the regulating tank 215 by the fixing hole 217, and one end of the regulating tank 215 is fixed on the secondary mould Near edge, the other end is fixed on the rotation section 21 near edge to tool 212.

The slip cylinder 30 is fixed on the two ends of the connecting portion 23, and sliding length is the width of the connecting portion 23, institute Press rods 40 are stated to be connected with the connecting portion 23 by the slip cylinder 30 and perpendicular to the slip cylinder 30.

It is the structural perspective of press rods described in the utility model 40 with continued reference to Fig. 3, the press rods 40 include ejection Cylinder 231, master mold 232 and pressure frame pipe sleeve 233, the ejection cylinder 231 are installed on inside the pressure frame pipe sleeve 233 At space, the master mold 232 ejects the one end of cylinder 231 to set reeded round roller and being fixed on.The slip cylinder 30 displacement can adjust to cooperate with the advance distance of the ejection cylinder 231.
