The specific embodiment
Be below specific embodiments of the invention by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiment.
As shown in Figures 1 to 4, this multi-angle hydraulic pipe bender comprises frame 1, in frame 1, be provided with the hydraulic cylinder 2 of horizontal positioned, at hydraulic cylinder 2 front ends, be provided with two pressing plates that be arranged in parallel up and down 3 and hydraulic cylinder 2 piston rod ends between two pressing plates 3, between two pressing plates 3, be provided with two moving blocks 4 and two moving blocks 4 and be symmetricly set on hydraulic cylinder 2 piston rod both sides, on two pressing plates 3, offer a plurality of locating hole 3a that are symmetrical set and be arranged in multiple row in the locating hole 3a of pressing plate 3 the same sides dip-parallel, moving block is inserted respectively admittedly in corresponding locating hole 3a and can circumferentially rotate in two ends Shang Xia 4, in frame 1 one sides, guide post 5 is installed and on guide post 5, is provided with stopper 6, and when tubing through between two pressing plates 3 during gap the end of tubing can be resisted against on stopper 6.
By moving block 4 being arranged between two pressing plates 3, thereby make tubing moving block 4 when carrying out crooked work there will not be the phenomenon of rocking, stability during assurance work, moving block 4 can circumferentially rotate simultaneously, make tubing when flexural deformation, moving block 4 rotates and drives position that tubing is resisted against moving block 4 originally along with bending work is moved to hydraulic cylinder 2 piston rod moving directions, avoids tubing with moving block 4, stuck phenomena to occur when mobile or because moving block 4 and outer pipe wall contact the situation that causes outer pipe wall to cave in firmly.
At hydraulic cylinder 2 piston rod strokes, constant in the situation that, in the time of in moving block 4 is inserted the solid locating hole 3a at same a line or same row, moving block 4 is the closer to cylinder piston rod, and tubing flexibility is less.
When needs carry out bending work to tubing, first according to tubing, need bend bit position to adjust the position of stopper 6 on guide post 5, again according to the diameter of tubing and tubing need crooked angle adjust moving block 4 need to insert solid on pressing plate 3 position of concrete locating hole 3a, finally tubing is inserted in two pressing plates 3 and pipe end is resisted against on stopper 6, primer fluid cylinder pressure 2, makes Tube Bending Deformation thereby tubing is applied to a thrust by hydraulic cylinder 2 piston rods.
Further, the pressing plate 3 that is positioned at below is fixedly mounted in frame 1, and the pressing plate 3 that is positioned at top is articulated and connected on hydraulic cylinder 2, and moving block 4 is axially fixed on pressing plate 3 by bolt.When adjusting the position of moving block 4 on pressing plate 3, moving block 4 need to be inserted admittedly on other locating holes 3a, after therefore first moving block 4 being unscrewed, be opened the pressing plate 3 of top, again moving block 4 is plugged into corresponding locating hole 3a upper, finally covers pressing plate 3 and again screw moving block 4.
Further, on moving block 4 periphery walls, offer a plurality of circumferential equally distributed arc groove 4a, when tubing interts between two pressing plates 3, primer fluid cylinder pressure 2, hydraulic cylinder 2 piston rods withstand on the outer wall of tubing and to tubing and carry out bending work, now the stress point on tubing withstands on the position at tubing place except hydraulic cylinder 2 piston rods, also have two stress points to be tubing and be resisted against the position on moving block 4, by being opened in the arc groove 4a on moving block 4 periphery walls, tubing periphery wall is resisted against in arc groove 4a and with plane-plane contact at the bottom of arc groove 4a, thereby increased the contact area of tubing periphery wall and arc groove 4a, avoid pressure that tubing bears in BENDING PROCESS too to concentrate and cause the situation of tubing distortion.
Further, stopper 6 is fixed on guide post 5 by bolt is sheathed, when needs are adjusted tubing and are needed bend bit position, first unscrew bolt, stopper 6 is moved axially until stopper 6 and hydraulic cylinder 2 piston rod vertical line distances need crooked position to the distance of pipe end for tubing along guide post 5, because hydraulic cylinder 2 piston rods are constant to frame 1 sidewall (this sidewall is that frame 1 is for installing the sidewall of guide post 5) air line distance, therefore stopper 6 and hydraulic cylinder 2 piston rod vertical line distances are stopper 6 to the distance of frame 1 sidewall and add that hydraulic cylinder 2 piston rods to the air line distance of frame 1 sidewall is tubing and needs crooked position to the distance of pipe end, now stop mobile stopper 6, and again screw bolt stopper 6 is retightened on guide post 5, then tubing is inserted between two pressing plates 3 and pipe end is resisted against on stopper 6, the position that now tubing faces hydraulic cylinder 2 piston rods is tubing needs crooked position, this structure can accurately be controlled tubing needs crooked position, position, avoids the long situation that needs cutting to cause the wasting of resources in its one end after bending pipes.
Further, on guide post 5, be carved with scale, by the scale on guide post 5, can need crooked position to the distance of pipe end to come accuracy controlling stopper 6 in the position of guide post 5 according to tubing, accuracy be high.
Further, on hydraulic cylinder 2, be provided with a mount pad 10, in mount pad 10, be interspersed with the screw rod 8 be arrangeding in parallel with hydraulic cylinder 2 piston rods, and the head end of screw rod 8 is connected with hydraulic cylinder 2 piston rods by contiguous block, the tail end of screw rod 8 be threaded adjusting nut 9 and when screw rod 8 moves axially adjusting nut 9 can be resisted against on mount pad 10.When the tubing of diameter of the same race is carried out to bending machining, in the situation that moving block 4 is arranged on the invariant position on pressing plate 3, by adjusting the position of adjusting nut 9 on screw rod 8, carry out the stroke of regulator solution cylinder pressure 2 piston rods, hydraulic cylinder 2 piston rod strokes are different, and when tubing is carried out to crooked work, the flexibility of bending pipes part is also different.
Further, in hydraulic cylinder 2 piston rod ends, be fixed with arc jacking block 7, the arcwall face of arc jacking block 7 faces hydraulic cylinder 2 piston rods and ejects direction, and along circumferential direction, offers deep-slotted chip breaker 7a on this arcwall face.When piston rod ejects, the deep-slotted chip breaker 7a on arc jacking block 7 is resisted against on the outer surface of tubing, and arc jacking block 7 is contacted with tubing face, avoids thrust that tubing bears in BENDING PROCESS too to concentrate and causes the situation of tubing distortion.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various modifications or supplement or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
