Abstract
The utility model provides a novel pipe bending die and a pipe bending machine with the novel pipe bending dies. The novel pipe bending die comprises an upper die and a lower die, wherein die splitting surfaces are formed at the joint of the upper die and the lower die, and the outer circumference of the die splitting surface of the upper die and the outer circumference of the die splitting surface of the lower die are provided with concave positions respectively. When the upper die and the lower die are assembled, the concave position of the upper die and the concave position of the lower die form a groove used for allowing a pipe fitting to be embedded into. A limiting structure for preventing the pipe fitting from being disengaged from the groove is arranged at one end of the groove. Due to the facts that the vertical die splitting mode is adopted and the groove is divided into two parts from the die splitting faces, when the pipe fitting is bent by more than 180 degrees, the pipe fitting can be separated from the dies only by separating the upper die from the lower die, and the requirement for over-180-degree bending is achieved.

The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing, for specific embodiment of the utility model, be explained and illustrated.
The direction that indicates L in Fig. 1 is left and right directions, and the direction that indicates B is fore-and-aft direction.
As shown in Figure 3 and Figure 4, a kind of Novel elbow pipe mould 11, comprise: patrix 111 and counterdie 112, the joint portion of patrix 111 and counterdie 112 forms die joint 117, the excircle of the die joint 117 of patrix 111 and counterdie 112 is equipped with recess 119, when patrix 111 and counterdie 112 matched moulds, the recess 119 of patrix 111 and counterdie 112 forms for holding the groove 116 of pipe fitting 3; One end of groove 116 is provided with the position limiting structure 115 that restriction pipe fitting 3 departs from from groove 116.
Owing to adopting the pattern of upper and lower parting, groove 116 is divided into two parts from die joint 117, therefore, when pipe fitting 3 bendings surpass 180 °, as long as by upper and lower mould 112 separately, the width of opening of the pipe fitting 3 after bending only need reach and be positioned at the locating shaft 4 at Novel elbow pipe mould 11 centers and the driving shaft external diameter of the first hydraulic cylinder just can be realized the separated of pipe fitting 3 and mould, has realized the demand over 180 ° of bendings.
Patrix 111 and counterdie 112 are cylinder, and position limiting structure 115 is located at cylindrical side.Position limiting structure 115 can be made one and embed cylindrical cuboid, also can make other shape, as long as reach restriction pipe fitting 3 object separated with mould.
Patrix 111 and counterdie 112 are provided with two crossing sections near a side of position limiting structure 115.
When patrix 111 and counterdie 112 matched moulds, the recess 119 and the position-limit mechanism that are positioned at die joint 117 form manhole.Groove 116 at clamping part patrix 111 and counterdie 112 is combined the shape that forms through hole, is in order to be conducive to the clamping of pipe fitting 3.Therefore, in fact also can make a complete round shape.
Due to when bending, be by rotating Novel elbow pipe mould 11, to reach the object of bending pipe fitting 3.Therefore in bending process, pipe fitting 3 can be pressed in the groove 116 between patrix 111 and counterdie 112 die joints 117, for this reason, the groove 116 being combined at kink patrix 111 and counterdie 112 can not surpass the shape of semicircle, otherwise there will be pipe fitting 3 to press situation that not enter groove 116.But if groove 116 does not reach semi-circular shape, the pardon of 116 pairs of pipe fittings 3 of groove meeting variation, so optimal cases is that groove 116 is semi-circular through hole.
Described Novel elbow pipe mould 11 is also provided with base 113, and described counterdie 112 is fixed on base 113.
