Technical field
The utility model flexible pipe terminal mould is specifically related to a kind of flexible die of wound form bending machine.
Background technology
The mould of bending machine is made up of bending die, clamping claw, servo-actuated chute or roller and straight core print at present.This die set is difficult to realize bending thin-walled small-bend radius pipe fitting, light-wall pipe is meant the relative wall thickness in the art: pipe wall thickness/tube outer diameter＜0.04, small-bend radius is a relative bending radius: the pipe of tube bending radius/tube outer diameter≤2, use existing mold when bending the minor radius light-wall pipe, can cause the ovality that bends pipe fitting overproof, the inboard wrinkling defective of crooked position.
The utility model content
The utility model overcomes the deficiency that prior art exists, and problem to be solved is: a kind of flexible pipe terminal mould is provided.
In order to address the above problem, the scheme that the utility model adopts is: the flexible pipe terminal mould mainly comprises straight core print, bending die, clamping claw, and the back of straight core print is connected with a multi-directional ball core print at least.
Described multi-directional ball core print is made up of ball core print, middle interior connector, middle outer shroud and following connector, the structure of multi-directional ball core print is passed through the screw rod suit of lower end by connector and following connector in middle for the ball core print, outer shroud in the middle of the outer face of middle interior connector is set with.
Described ball core print is " people " font, and its top is the ball-type connector, and its middle part is provided with inside draw-in groove, and its underpart end face is provided with the screw thread of connecting screw rod, and the groove that adapts with its top ball-type connector inwardly is set in the middle of the end face of its underpart.
The structure of connector is in the described centre: the middle part of connector is provided with through hole in middle, middle in the inboard of connector be provided with the ball-type cambered surface that the ball-type connector with the ball core print adapts.
The structure of outer shroud is in the middle of described: the outer face of middle outer shroud is provided with the ball-type cambered surface, the outside of interior connector in the middle of the inner face of middle outer shroud is sleeved on.
Described connector down is the entity that end face is provided with through hole.
The utility model flexible pipe terminal mould is connected with the multi-directional ball core print by straight core print, can be according to the diameter of pipe and the different multi-directional ball core prints of making different sizes of bending radius, the multi-directional ball core print is by the ball core print, connector in middle, middle outer shroud and following connector are formed, the structure of multi-directional ball core print is passed through the screw rod suit of lower end by connector and following connector in middle for the ball core print, outer shroud in the middle of the outer face of connector is set with in middle, the outer face of middle outer shroud is provided with the ball-type cambered surface, the multi-directional ball core print can become tube bending the bend pipe of same internal diameter neatly, and bend pipe carried out set round, can be not wrinkling.
Description of drawings
Below in conjunction with accompanying drawing the utility model flexible pipe terminal mould is further specified:
Fig. 1 is the structural representation of flexible pipe terminal mould of the present invention;
Fig. 2 is the enlarged diagram of multi-directional ball core print 3 in the flexible pipe terminal mould shown in Figure 1;
Fig. 3 is the structural representation of connector 6 in the centre shown in Figure 2;
Fig. 4 is the structural representation of connector 8 down shown in Figure 2.
The specific embodiment:
Flexible pipe terminal mould shown in Fig. 1-4 mainly comprises straight core print 1, bending die 2, clamping claw, and the back of straight core print 1 is connected with 3 multi-directional ball core prints 3.Each multi-directional ball core print 3 is made up of 6,1 middle outer shroud 7 of connector in 5,6 centres of 1 ball core print and 6 following connectors 8, the structure of multi-directional ball core print 3 is that ball core print 5 passes through the screw rod suit of lower end by middle interior connector 6 and following connector 8, outer shroud 7 in the middle of the outer face of middle interior connector 6 is set with.The structure of ball core print 5 is: ball core print 5 is " people " font, its top is the ball-type connector, its middle part is provided with inside draw-in groove, and its underpart end face is provided with the screw thread of connecting screw rod, and the groove that adapts with its top ball-type connector inwardly is set in the middle of the end face of its underpart.The structure of connector 6 is in middle: the middle part of connector 6 is provided with through hole in middle, middle in the inboard of connector 6 be provided with the ball-type cambered surface that the ball-type connector with ball core print 5 adapts.The structure of middle outer shroud 7 is: the outer face of middle outer shroud 7 is provided with the ball-type cambered surface, the outside of interior connector 6 in the middle of the inner face of middle outer shroud 7 is sleeved on.Following connector 8 is provided with the entity of through hole for end face, connector 6 and middle outer shroud 7 in the middle of hold the upper surface of following connector 8, the draw-in groove of the ball core print 5 of next multi-directional ball core print 3 is blocked in the inboard of following connector 8, make in the ball core print 5 spacing endosphere die cavities that connector 6 forms in ball core print 5 and centre, connect thereby form universal ball.
In the tube bending process, straight core print 1 is positioned at the flexural center all the time or slightly is ahead of the flexural center among the figure, and multi-directional ball core print 3 is deep in the bending deformation area of pipe, and crooked with steel pipe 4, multi-directional ball core print 3 limits the ovalizing deflection of steel pipe internally.Bending die 2 is from the distortion of outside restriction steel pipe.Extract straight core print 1 and multi-directional ball core print 3 out and can carry out set round by means of oil cylinder behind the tube bending pipe.
The installation method of multi-directional ball core print 3 is: the screw rod with ball core print 5 bottoms all connects earlier, the ball core print 5 that will be connected with screw rod is again arranged one by one from top to down, connector 6 in the middle of cover is packed into then, the outer end of connector 6 in the middle of then middle outer shroud 7 covers being packed into, connector 8 under cover is packed into again gets final product ball core print 5, middle interior connector 6 and 8 lockings of following connector with screw rod at last.
