As shown in Figures 2 to 6, the first described bending apparatus 5 includes being located at the first cover half The first curved portions 51 on 31 and be located at the first arcuate socket 52 supported on platform 2, described the Being provided with in one arcuate socket 52 can be within it along the first moving lever 53 of movement in a curve, described One moving lever 53 be provided with coordinate with the first curved portions 51 and make pipe fitting 100 bend first curved Folding wheel 54, described frame 1 is provided with the first driving machine driving the first moving lever 53 motion Structure 55；The second described bending apparatus 6 includes the second curved portions being located on the second cover half 41 61 and be located at the second arcuate socket 62 supported on platform 2, it is provided with in the second described arcuate socket 62 Can be within it along the second moving lever 63 of movement in a curve, the second described moving lever 63 is provided with The the second bending wheel 64 coordinated with the second curved portions 61 and make pipe fitting 100 bend, described machine Frame 1 is provided with the second drive mechanism 65 driving the second moving lever 63 motion.

As it is shown on figure 3, the first described drive mechanism 55 includes being located at the supported on platform 2 One drives cylinder 551, and the cylinder rod of the first described driving cylinder 551 connects the first tooth Bar 552, the first described tooth bar 552 and the first gear being connected on the first moving lever 53 553 coordinate；The second described drive mechanism 65 includes being located at the second driving supported on platform 2 Cylinder 651, the cylinder rod of the second described driving cylinder 651 connects and has the second tooth bar 652, The second described tooth bar 652 coordinates with the second gear 653 being connected on the second moving lever 63.

Operation principle:

First, the first clamping device 3 and the second clamping device 4 are in open mode.Put into one In root pipe fitting the 100 to the first clamping device 3 and the second clamping device 4.Then, adjustment is unclamped Bolt 93, promotes forward adjustment block 91, makes pipe fitting 100 be adjusted block 91 and promote forward, when When adjustment block 91 arrives desired position, locking adjusts bolt 93, thus have adjusted pipe fitting 100 It is exposed at the length outside the first clamping device 3, thus can make the length of the first bending segment 200 Being controlled, such benefit also includes when processing second pipe fitting 100, to pipe fitting 100 During clamping, the end of pipe fitting 100 is directly withstood in adjustment block 91, it can be ensured that processing every The length of the first bending segment 200 that root pipe fitting 100 finally obtains is equal.

When the length adjustment of the first bending segment 200 is complete, by unclamping regulation bolt 83, make Left support plate 21 moves relative to right support plate 22, during left support plate 21 moves, Second clamping device 4 thereon and the second bending apparatus 6 also follow movement, thus have adjusted pipe Part 100 other end is exposed at the length outside the second clamping device 4, thus can make the second bending The length of section 300 is controlled, and such benefit also includes when processing second pipe fitting 100, Position owing to one end of pipe fitting 100 is adjusted block 91, so every pipe fitting 100 other end is After the length of the second bending segment 300 that obtains equal.

After pipe fitting 100 is adjusted block 91 location, the first cylinder 35 promotes the first dynamic model 32, Therefore, first on the first dynamic model 32 moves first on arcuate groove 34 and the first cover half 31 calmly Pipe fitting 100 is clamped by arcuate groove 33.Meanwhile, the second cylinder 45 promotes the second dynamic model 42, therefore, second on the second dynamic model 42 moves on arcuate groove 44 and the second cover half 41 Two determine arcuate groove 43 clamps pipe fitting 100 opposite side.Then first cylinder 551 is driven to promote First tooth bar 552 action, the first tooth bar 552 promotes the first gear 553 to rotate, the first gear 553 drive the first moving lever 53 along movement in a curve in the first arcuate socket 52, the first trace On 53 first bending wheel 54 just coordinate just pipe fitting 100 to bend with the first curved portions 51 and Form the first bending segment 200.Then the first cylinder 35 and the second cylinder 45 are died, but first Dynamic arcuate groove 34 is determined arcuate groove 33 with first and is still closed, and second moves arcuate groove 44 and second determines Arcuate groove 43 still closes, and simply pipe fitting 100 is not had clamping force.Then regulation cylinder 72 Promoting swinging plate 71 to rise, swinging plate 71 promotes the first bending segment 200 during rising, Therefore, the holding position of relative first clamping device 3 of the first bending segment 200 occurs upwards to reverse, The angle of the first bending segment 200 is just adjusted, and adjusts regulation cylinder 72 by screw rod 76 Stroke can regulate the windup-degree of the first bending segment 200.Why by before windup-degree One cylinder 35 and the second cylinder 45 are died, and are to just can reverse the first bending by less power Section 200, the most not only size accurately but also will not sprain pipe.If the first cylinder 35 and Two cylinders 45 are not died, and the first cylinder 35 and the second cylinder 45 can hold very tight, regulation Cylinder 72 is accomplished by the biggest power just can make the first bending segment 200 reverse, and pipe fitting 100 At the position reversed, damage easily occurs, resilience occurs simultaneously, it is impossible to ensure the essence of windup-degree Really requirement.

Then the first cylinder 35 and the second cylinder 45 are ventilated again, and pipe fitting 100 is clamped again. Then second driving cylinder 651 to promote the second tooth bar 652 action, the second tooth bar 652 promotes the Two gears 653 rotate, and the second gear 653 drives the second moving lever 63 at the second arcuate socket 62 Interior along movement in a curve, the second bending wheel 64 on the second trace 63 just with the second curved portions 61 coordinate and are bent by pipe fitting 100 and form the second bending segment 300.Two bent after the One cylinder 35 and the ventilation of the second cylinder 45 are return, and manually take out pipe fitting.

Therefore, the second bending segment 300 is positioned at horizontal plane, and the first bending segment 200 relative The holding position of one clamping device 3 there occurs torsion, and therefore, the first bending segment 200 is just with second Bending segment 300 is not in approximately the same plane, but mutually in different surface beeline (the most as shown in Figure 7). The whole course of processing completes on a machine, only needs clamping once, and production efficiency is greatly improved, And steady quality.
