Description
Technical field
The utility model relates to a kind of pipe fitting bending apparatus, particularly relates to a kind ofly can bending out about bending machine from having concurrently of asymmetric three-dimensional contouring to the bend pipe function to pipe fitting both ends.
Background technology
As shown in Figures 1 and 2, existing a kind of bending machine (TaiWan, China application case number No. 92105312 patent case) includes fixedly die holder 2 and two that a board 1, is installed in the middle of this board 1 and is separately positioned on this fixedly bend pipe head 3 of die holder 2 both sides.Should be fixedly die holder 2 have one fixedly fixture block 201 and one can with respect to this fixedly fixture block 201 generation closings with the movable clip block 202 of clipping one pipe fitting.Aforementioned bend pipe head 3 respectively has a movable mould wheel 301, and can be located on this toggling device 302 and with respect to this movable mould wheel 301 with respect to the toggling device 302 and that this movable mould wheel 301 produces swings and be the eccentric curved mould wheel 303 that is provided with.When the pipe fitting stage casing be subjected to this fixedly die holder 2 clippings locate, and two ends also are clamped in the movable mould wheel 301 of bend pipe head 3 and should take turns between 303 by curved mould, and when driving 302 swings of this toggling device and driving curved mould wheel 303, just can make these pipe fitting two ends finish the bend pipe operation with respect to movable mould wheel 301 swings.
Though this bending machine can carry out the bend pipe operation to pipe fitting because when bend pipe, this fixedly 2 of die holders to the pipe fitting clipping, so can only bend the pipe fitting that extends (dual space) on same plane.
Again as shown in Figure 3, the bending machine (United States Patent (USP) the 4th, 843, No. 861 cases) of another kind of two curved formulas, it comprises is located at the swan neck system 5 that middle rotating and clamping device 4 and two is located at these rotating and clamping device 4 both sides.As Fig. 4, Fig. 5 and shown in Figure 6, this rotating and clamping device 4 have a shell block 401 and be installed in a power unit 402 of these shell block 401 inside, a gear unit 403, a brake units 404, fastens a unit 406 and an idle pulley unit 407 in order to the driver element 405, that drives this brake units 404.This gear unit 403 and brake units 404 respectively have the external gear 403 that an internal gear 403 ', 404 ' and two is located at this internal gear 403 ', the 404 ' outside ", 404 ", this fastening unit 406 also have one with the interior clip wheel 408 of aforementioned internal gear 403 ', 404 ' engagement and two can with external gear 403 ", 404 " the outer clip wheel 409 of engagement, should in clip wheel 408 inside have grip hold arc face 408 ' in, aforementioned outer clip wheel 409 inside then respectively have one and are the outer grip hold arc face 409 ' of eccentric setting with respect to grip hold arc face 408 ' in this.When a motor 405 ' that starts this driver element 405, be to make the internal gear 404 ' of this brake units 404 check the location, this interior clip wheel 408 that fastens unit 406 also produces the location, and when power unit 402 input power, and utilize the external gear 403 of this gear unit 403 and brake units 404 ", 404 " when the outer clip wheel 409 of this fastening unit 406 of interlock produces eccentric rotation with respect to clip wheel in this 408, utilize the rotation that should outer grip hold arc face 409 ' be off-centre just can cooperate and with a pipe fitting clipping with grip hold arc face 408 ' in this.When discharging brake, clip wheel 408 and pipe fitting rotated together in outer clip wheel 409 just can drive, and adjusted the phase place purpose to reach.
Though the rotating and clamping device 4 of this bending machine can also can carry out the phase place adjustment, to reach the stereo bent pipe purpose with the moving location of pipe fitting clamping between the operation of secondary bend pipe.
But this bending machine overall architecture and rotating and clamping device 4 still have following disappearance:
One, the mobile range of swan neck system 5 is to be the boundary with this rotating and clamping device 4, and is synchronously symmetrical bending process to be carried out at the two ends of this pipe fitting, and is not suitable for the asymmetric pipe fitting processing in two ends.
Two, when adjusting phase place, clip wheel 408 is not subjected to the direct driving of this power unit 402 in this, but is dragged passively because of the clipping frictional force of pipe fitting, and the danger that pipe fitting gets loose takes place easily.
Three, constituent components is many, can cause overall volume big, uses (as bend external diameter 9mm locomotive oil pipe) for the bend pipe of some light clamping loads, does not need so complicated mechanism in fact.
The utility model content
It is a kind of simple in structure and can bend out about bending machine from having concurrently of asymmetric three-dimensional contouring to the bend pipe function at pipe fitting both ends that the purpose of this utility model is to provide.
To the bending machine of bend pipe function, comprise the rotating and clamping device and that a board, is arranged on this board and can produce the swan neck system of displacement about the utility model has concurrently along this board.This board is to extend along a length direction, and has that one first side, is with this first side that end face and two that second side, of opposite setting extends to this second side by this first side is arranged on this end face and along the guide rail of this length direction extension.This rotating and clamping device is arranged between first and second side of this board, and have the shell block, of being located at this top face and be installed in power unit, on this shell block to be installed in this shell block inner and be subjected to the rotating unit and of this power unit interlock to be installed in the fastening unit of this rotating unit inside, this fastens unit can be with this pipe fitting clipping, and utilizes this rotating unit to rotate and adjust phase place.This swan neck system is to produce displacement and to slide into second side by first side of this board along this guide rail, and has a pedestal that bridges on this board end face, one can produce the slide of lifting perpendicular to the vertical direction of this length direction with respect to this pedestal and along one, one is that the pivot central shaft is located at revolving bed and on this slide and is installed in bend pipe mould on this revolving bed with a first axle that is parallel to this vertical direction, this revolving bed is in a primary importance between this first side and this rotating and clamping device, this revolving bed when this second side slides, is in a second place by this rotating and clamping device by this primary importance pivot turnback and position.
Whereby, utilizing this rotating and clamping device and to adjust phase place to pipe clamp system, and utilize this rotating and clamping device to cooperate with this swan neck system, is to bend out asymmetric moulding to the pipe fitting both ends, and this swan neck system is simple in structure, can reduce cost.
