The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments, can be implemented so that those skilled in the art can better understand the present invention also, but illustrated embodiment is not as a limitation of the invention.
As Fig. 1～shown in Figure 3, pipe bender of the present invention comprises instrument pincers 1, instrument pincers 1 wherein be connected with turning rolls 9 on the jaw 4, turning rolls 9 is provided with fixed wheel 6; Also be provided with chute 7 on the turning rolls 9, be provided with slidably movable supporting board 14 in the chute 7, movable supporting board 14 is provided with roller 10, is equipped with groove on the periphery of this roller 10 and aforementioned fixed wheel 6, and roller 10 is relative with fixed wheel 6, between form the clamp space; Be connected with handle 13 on the turning rolls 9; Described turning rolls 9 can relatively rotate for axle the junction with instrument pincers 1.Be respectively equipped with on two jaws 4 of instrument pincers 1 on the relative face of the fixing card of 2, two on fixing card 2 and be respectively equipped with V-shaped groove 16.Fixing card 2 is hinged on the described jaw 4, make fixing card 2 can instrument clamp 1 with the relative Plane of rotation of turning rolls 9 in swing.
Wherein, turning rolls 9 can directly be hinged on the jaw 4 of instrument pincers 1, also can be connected on the jaw 4 of instrument pincers 1 by a support plate 8, between the jaw 4 of support plate 8 and instrument pincers 1 for fixedlying connected, be connected through the hinge between support plate 8 and the turning rolls 9, thereby instrument pincers 1 can be relatively rotated with turning rolls 9.
As a preferred embodiment of the present invention, the hinge between support plate 8 and the turning rolls 9 can adopt one 5, and this axle 5 passes turning rolls 9, support plate 8 and fixed wheel 6 backs and fixed by nut.Like this, the axle of hinged turning rolls 9 and support plate 85 also is used to fixed wheel 6 is installed simultaneously, makes pipe bender more compact structure of the present invention, and volume is littler, to be suitable for the pipe of minor diameter.
On movable supporting board 14, be provided with and regulate and positioner,, and be located when needed with the position of adjusting roller 10.As a kind of preferred version of this structure, can be at turning rolls 9 end formation a junction 12 away from fixed wheel 6, handle 13 passes this connecting portion 12 and is threaded with connecting portion 12 formation; Described handle 13 is by marking closely 11 or otherwise be pivotally connected on the movable supporting board 14.Like this, turning handle utilizes the threaded engagement between handle 13 and the connecting portion 12, can regulate the position of roller 10, also can realize the location simultaneously.This simple in structure, and easy to use.Certainly, can also other multiple structure realize regulating and the location, for example adopt worm structure etc.
Groove on the periphery of fixed wheel 6 and roller 10 can equal the external diameter of the pipe that will bend for the diameter in the formed relatively clamp of deep-slotted chip breaker 17 space on 17, two faces of deep-slotted chip breaker.The benefit of deep-slotted chip breaker is that tubing place wall and fixed wheel 6, roller 10 are closely cooperated, and makes tubing not yielding in when bending, but that shortcoming is the scope of application is little, only is applicable to the tubing of respective diameters, for the tubing of different-diameter, needs to change fixed wheel and roller.Groove on the periphery of fixed wheel and roller also can be V-shaped groove, and the benefit of being arranged to V-shaped groove is the tubing that can be suitable for different-diameter.
Pipe bender of the present invention in use, at first turning handle 13, regulate the position of movable supporting board 14 in the chute 7 of turning rolls 9, make the spacing maximum between fixed wheel 6 and the roller 10, so that tubing stretches into.When tubing passes the rhombus groove district that fixing card 2 synthesizes, fixing card 2 floats, the rhombus groove district of being convenient to the synthesize adjustment that swings, after regulating correct position, instrument pincers 1 are clamped, tighten handle 13 axially-movables again, tubing is placed between the arc groove of fixed wheel 6 and roller 10 and fix, rotary handle 13 arms are realized bend pipe at any angle.Referring to Fig. 4 to Fig. 7, the present invention can be bent into tubing 90 degree, 180 degree even angles arbitrarily.
Specifically, support plate 8 is fixed on the instrument pincers 1, belongs to axial restraint, realizes clamping motion.Fixing card 2 floats, and can swing on the plane that is parallel to support plate 8, and such purpose is, along with the change of fixed wheel 6 sizes, the fixing card 2 that floats can corresponding swing to change clamping position.
In same plane, vertical direction, tubing drives fixing card 2 lockings by the instrument pincers, in the horizontal direction simultaneously, tubing drives roller 10 horizontal movements by handle 13, and tubing passes the synthetic horizontal direction arc groove of the synthetic vertical direction rhombus grooves of fixing card 2 and fixed wheel 6, roller 10 simultaneously, regulates correct position, for the rotoflector motion ready.
When tubing at desired correct position after the time locking, the left hand instrument pincers 1 of holding with a firm grip, right hand rotary handle 13 arm of forces, tubing along the rotational trajectory of roller 10, is that pivot rotates arbitrarily with fixed wheel 6 under the effect of the arm of force, according to arm of force institute cradle angle degree, realize the angle of bend of tubing.
Omnipotent pipe bender of the present invention is particularly useful for diameter of phi 6 following metric systems, made in Great Britain tubing, and the structure unanimity can be changed fixed wheel 6, roller 10, cooperates with the tubing of respective diameters, realizes above-mentioned any bend pipe effect.
Moreover; but the continuous bend pipe of pipe bender especially of the present invention implementation space arbitrary plane is fixed the unsteady orientation of blocking, and adjusts the swing position of tubing at any time along with the change of fixed wheel size; both protect tubing to be difficult for distortion, also can adjust the control of any bend pipe direction and angle.
The above embodiment is the preferred embodiment that proves absolutely that the present invention lifts, and protection scope of the present invention is not limited thereto.Being equal to that those skilled in the art are done on basis of the present invention substitutes or conversion, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
