Abstract
The invention relates to a pipe bending machine which comprises a horizontally-arranged fixed base. The pipe bending machine is characterized in that a rotary base is horizontally and rotatably arranged on the fixed base; a pipe bending driving wheel is concentrically and fixedly arranged on a rotary shaft of the rotary base; pipe bending driven wheels are horizontally and rotatably arranged on the fixed base; a bending crack is formed among the pipe bending driving wheel and the pipe bending driven wheels; a locking assembly composed of a fixed locking block and a movable locking block is arranged on the rotary base, and a locking crack is formed between the fixed locking block and the movable locking block. The bending curve of a pipe is limited by cooperation of the pipe bending driving wheel and the pipe bending driven wheels, the pipe is locked through cooperation of the fixed locking block and the movable locking block, the pipe is rotated and drawn, and therefore the pipe is bent precisely and efficiently. The clamping face of the fixed locking block is tangential to the pipe bending driving wheel, and therefore the pipe is drawn and bent more smoothly. The pipe bending driven wheels can move horizontally and linearly, and therefore the width of the bending crack can be adjusted to adapt to bending of pipes of different thicknesses.
Description
Technical field
The present invention relates to a kind of bending machine.
Background technology
The operation principle of existing bending machine is: be placed on by metal tube in the mould that links with line shaft, pressure roller extruding is fixing, during work, line shaft driven mold and metal tube move together, metal tube is made to be bent into the bend pipe of required angle along mould, because metal tube is that frictionally pulls advance, therefore in bend pipe process, pipe fitting knee outer wall easily causes the problem of fracture, or pipe fitting knee inwall easily causes the problem of fold.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of bending machine.
Described a kind of bending machine, comprises horizontally disposed fixed pedestal, it is characterized in that described fixed pedestal horizontally rotates being provided with rotating basis; The rotating shaft of described rotating basis is fixedly installed bend pipe driving wheel with one heart; Described pedestal horizontally rotates and is provided with bend pipe follower; Bending crack is formed between described bend pipe driving wheel and bend pipe follower; Described rotating basis is also provided with the locking assembly be made up of fixing lock dog and movable lock dog, between described fixing lock dog and movable lock dog, forms locking crack.
Described a kind of bending machine, is characterized in that described fixing lock dog is fixedly installed on rotating basis, its clamping face and bend pipe driving wheel tangent.
Described a kind of bending machine, is characterized in that described bend pipe follower can horizontal linearity move.
Described a kind of bending machine, is characterized in that described rotating basis is driven by motor and rotates.
The present invention passes through the bending curve of the cooperation restriction tubing of bend pipe driving wheel and bend pipe follower, locks tubing, rotation traction traction tubing, thus accurately complete the bending of tubing efficiently by fixing lock dog and movable lock dog; Fixing lock dog clamping face and bend pipe driving wheel tangent, the traction of tubing is bent more smooth; Bend pipe follower energy horizontal linearity moves, thus the width that can adjust bending crack bends with the tubing adapting to different thicknesses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the right TV structure schematic diagram of Fig. 1.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described:
This bending machine comprises the fixed pedestal 1 that fixing horizontal is arranged, and fixed pedestal 1 rotates and is provided with rotating basis 2, rotating basis 2 can horizontally rotate on fixed pedestal 1.Be provided with motor below fixed pedestal 1, rotate in order to drive rotating basis 2.Rotating basis 2 is provided with bend pipe driving wheel 3, fixing lock dog 4 and movable lock dog 6.Be fixedly installed bend pipe driving wheel 3 with one heart on the rotating shaft of rotating basis 2, the wheel face of bend pipe driving wheel 3 offer the semicircular bending groove 13 of a circle.The right of bend pipe driving wheel 3 is fixedly installed a fixing lock dog 4, and the lower surface of fixing lock dog 4 is cross section is semicircular locking slot 14, locking slot 14 be left and right towards straight-line groove, and tangent with the lower end of bend pipe driving wheel 3.The below of fixing lock dog 4 is fixedly installed movable lock dog shell 8, in movable lock dog shell 8, movable lock dog 6 is set, movable lock dog 6 can move up and down and lock in movable lock dog shell 8, the upper surface of movable lock dog 6 is also the locking slot 14 of cross section semicircular in shape, lock crack 12 with the locking slot 14 of fixing lock dog 4 formation one of being separated by, fixing lock dog 4 and movable lock dog 6 and movable lock dog shell 8 etc. form tubing locking assembly jointly.
Fixed pedestal 1 is fixedly installed a follower shell 7, it is positioned at the below of bend pipe driving wheel 3, a motion bar is provided with in follower shell 7, this motion bar can move up and down and lock in follower shell 7, the upper end of motion bar is rotated and is provided with two bend pipe followers 5, these two bend pipe follower 5 left-right situs, the bend pipe follower 5 on the right and bend pipe driving wheel about 3 are point-blank.The wheel face of bend pipe follower 5 also offers the semicircular bending groove 13 of a circle, bend crack 11 with the bending groove 13 of bend pipe driving wheel 3 formation one of being separated by.Bending crack 11 and locking crack 12 are co-located on straight line.
Fixedly mount an electric cabinet 9 in the lower left of fixed pedestal 1, electric cabinet 9 is arranged switch 10, rotate in order to the motor switch controlled under fixed pedestal 1 to drive rotating basis 2 or stop.
When the work of this bending machine, first bend pipe follower 5 and movable lock dog 6 are moved down, bending crack 11 and locking crack 12 are opened, tubing is put into bend pipe crack 11 and locking crack 12; Upwardly bend pipe follower 5, makes bending groove 13 be clamped by tubing, then locks bend pipe follower 5, more upwardly movable lock dog 6, coordinates fixing lock dog 4 that tubing is locked by locking slot 14, then locking activity lock dog 6; Open switch 10, motor drives rotating basis 2 to be rotated counterclockwise, the stiff end of locking assembly traction tubing is rotated counterclockwise, the movable end of tubing is limited point-blank all the time by two bend pipe followers 5, under the effect of bend pipe driving wheel 3, tubing is bent out the curved of circle accurately, thus efficiently completes the bending of tubing accurately.
