Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, with reference to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3 known, a kind of simple portable thin-walled tube bending device, comprise mainboard 1, bending die 2, key 3, axle 4, clamping plate 6, back pressure wheel 7, pin 8, right angle handle 9, cross bar 10, spring 11, ball rod 12, roller mount 13 and guide wheel 14, mainboard 1 bottom is provided with the axle 4 that work is with it joined, axle 4 left end is provided with the bending die 2 be connected by key 3, bending die 2 is provided with clamping plate 6, be provided with it with dovetail groove mode roller mount 13 of joining alive in the middle part of mainboard 1, back pressure wheel 7 and guide wheel 14 is provided with in roller mount 13, mainboard 1 top is provided with shakes hands 9 by pin 8 right angle of joining alive with it, right angle handle 9 is transversely provided with an elongated hole, ball rod 12 is shaken hands 9 on by nut check at right angle through after described elongated hole with formula formula of living, mainboard 1 upper surface is provided with cross bar 10 affixed with it, spring 11 upper end and cross bar 10 affixed, lower end and roller mount 13 are connected, workpiece 5 diameter d that the back pressure wheel center line of 7 arranged in described roller mount 13 and the distance L of bending die 2 center line equal 0.3 ~ 0.5 times, and both wheel rim distance H equal 1 ~ 1.5mm, the wheel rim of described bending die 2 and back pressure wheel 7 and guide wheel 14 is equipped with reversible deformation arc groove, and the size of described reversible deformation arc groove is determined by with data in following table:
| R/d | r 1 | r 2 | r 3 | h |
| 1.5～2.0 | 0.5d | 0.95d | 0.37d | 0.56d |
| 2.0～3.5 | 0.5d | 1.0d | 0.4d | 0.54d |
| ≥3.5 | 0.5d | ≥1.0d | 0.5d | 0.5d |
In described table, R is the cross section neutral layer radius of workpiece 5, and d is the diameter of workpiece 5, r
1the reversible deformation arc groove radius of bending die 2, r
2the reversible deformation arc groove upper radius of back pressure wheel 7 and guide wheel 14, r
3be the reversible deformation arc groove bottom radius of back pressure wheel 7 and guide wheel 14, h is the reversible deformation arc groove degree of depth of back pressure wheel 7 and guide wheel 14.The utility model is used to carry out bend pipe, shape after bending and radius depend on bending die 2, BENDING PROCESS is completed by back pressure wheel 7 and guide wheel 14, can move up and down in the dovetail groove of roller mount 13 on mainboard 1 and be resetted by spring 11, during bend pipe, first axle 4 left end of the present utility model is clamped on bench vice, when operator hold right angle handle 9 rotate clockwise around pin 8 time, mainboard 1 will be driven to rotate around axle 4 together, now the bulb of ball rod 12 presses plane in roller mount 13, and exerted pressure to workpiece 5 by guide wheel 14 and produce moment of flexure, workpiece 5 is bent plastic deformation, and the effect of back pressure wheel 7 is exactly apply certain pressure at the crooked position of workpiece 5, make it to produce the ellipse that produces to offset tube bending of reversible deformation by the arc groove on wheel, and control fold to a certain extent, here, the bending quality of size to light-wall pipe of back pressure is vital, we can change the size of back pressure by the position of adjusting ball head bar 12, bending moment needed for a kind of metal tube flexural deformation is all certain, therefore on right angle handle 9, added power is also certain, the pressure of ball rod 12 suffered by bulb point is then relevant to the vertical range of pin 8 with this point, as long as by the adjustment to described vertical range, just can obtain the back pressure be applicable to.
