Description
Technical field
The invention belongs to machining technique field, particularly relate to a kind of bar apparatus for bending.
Background technology
Bending for Φ less than 10 bar, utilizes simple mould usually on arbor press, and to the bending that bar carries out repeatedly, school shape just can complete.Also need to analyze bend before bending, if the material of bool has enough plasticity, yield ratio is little, and the ratio of yield point and springform is little, is just conducive to the quality of bending forming and guarantee workpiece.Otherwise bending effect is poor, even cannot bend.
Utilize simple mould bending, workpiece size precision is low, and the precision at an especially U-shaped right angle is difficult to be guaranteed.Some U-shaped part also needs to manufacture and design special mould and just can machine, and such production cost is higher.And the frictional force of part and die is comparatively large in the process of bending, make the easy sassafras wound of piece surface, affect accessory appearance quality, the easy resilience of part after bending, needs pincers worker correction repeatedly, corrects difficulty large.
Therefore, the direction becoming these those skilled in the art and make great efforts how is solved the problems of the technologies described above.
Summary of the invention
Object of the present invention is just to provide a kind of bar apparatus for bending, can solve above-mentioned prior art Problems existing completely.
Object of the present invention is realized by following technical proposals:
A kind of bar apparatus for bending, the bending tool comprising base and be connected with drive unit, under the effect of drive unit, bending tool can move back and forth in the vertical direction up and down, base is provided with bending groove, in bending groove, interval arranges two bending rollers one, and bending tool is arranged at directly between two bending rollers one.
Further, described bending tool one end is connected with drive unit, and other end rotating shaft connects bending roller two, in the middle part of bending tool, be provided with slotted eye.
Further, on described base, symmetrical installation fixes right baffle-plate and right baffle plate, and between left and right baffle plate, form bending groove, two bending rollers one are arranged in bending groove by rotating shaft.
Further, stopper slot is circumferentially offered in described bending roller one surface.
Further, also comprise stopping means, this stopping means comprises fixed block, L shape locating piece, screw rod and spring, and described fixed block is fixed on base, and fixed block is offered the bar hole consistent with bending groove bearing of trend, L shape locating piece is fixed on bar hole by screw, nut, spring housing is connected on screw rod, and screw rod tail end is threaded with L shape locating piece, and is locked by locking nut, this screw rod is positioned at above bending groove, and parallels with bending groove.
Further, the head upper surface of described screw rod is the inclined-plane under being tilted to.The bar after a bending can be located in this inclined-plane, bar is leant against on this inclined-plane and positions, and avoids bar transition friction to produce impression.
Compared with prior art, beneficial effect of the present invention is: structure is simple, reasonable in design, can process the U-shaped part of different size and shape, can the bending at shaping U-shaped right angle, only needs pincers worker to correct a little after Bending Processing.The rebound degree of part is lower, and the part processed is without impression.Ensure that product quality, improve production efficiency, save production cost.Further, this apparatus structure manufacture is simple, and disassembly and assembly are convenient and swift, are particularly suitable for the U-shaped bending of Φ less than 10 bar.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
As shown in Figures 1 to 6, a kind of bar apparatus for bending, the bending tool 2 comprising base 1 and be connected with drive unit, the drive unit that the present embodiment adopts is palm punch press, bending tool 2 is connected with the main shaft of palm punch press, when palm punch press works, bending tool 2 can move back and forth in the vertical direction up and down.On base 1, symmetrical installation fixes right baffle-plate 3 and right baffle plate 4, bending groove 5 is formed between left and right baffle plate 3,4, installed between two bending rollers, one 6, two bending rollers 1 by rotating shaft in bending groove 5 and be spaced a distance, stopper slot 7 is circumferentially offered on described bending roller 1 surface.Described bending tool 2 is arranged between two bending rollers 1 directly over middle part, and this bending tool 2 one end is connected with palm punch press, and the other end offers U-lag hole 8, connects bending roller 29 in the end in U-lag hole 8 by rotating shaft.
In order to locate bar and adapt to different bending sizes, the U-shaped part of bending height, mounting limit device on right baffle-plate 3, this stopping means comprises fixed block 10, L shape locating piece 11, screw rod 12 and spring 13, described fixed block 10 is fixed on right baffle-plate 3, fixed block 10 is offered the bar hole 14 consistent with bending groove 5 bearing of trend, L shape locating piece 11 passes through screw, nut is fixed on bar hole 14, spring 13 is socketed on screw rod 12, screw rod 12 tail end is threaded with L shape locating piece 11, and locked by locking nut 15, the head upper surface of screw rod 12 is the inclined-plane 16 under being tilted to, lower surface is the inclined-plane that symmetry tilts upward, this screw rod 12 is positioned at above bending groove 5, and parallel with bending groove 5.
See Fig. 7 to Fig. 9, in use, the base 1 of this device is fixed on the work top of arbor press by screw or pressing plate, bending tool 2(is equivalent to punch) be fixed on the main shaft of arbor press, base 1 is adjusted to suitable position, be placed on by bar 17 in the stopper slot 7 of bending roller 1, the cambered surface of stopper slot 7 and the face of cylinder of bar 17 fit, and the gap between two bending rollers 1 is equivalent to die.Different highly different with bending according to the bending size of part, L shape locating piece 11 can move along the bar hole 14 on fixed block 10, thus the position of adjusting screw(rod) 12, screw rod 12 coordinates for locating bar 17 and inching with spring 13.The main shaft of palm punch press drives bending tool 2 vertical downward movement, the gap between bending roller 29 extruded bar stock 17 to two bending rollers 1 of bending tool 2 end, thus bending bar 17, and repeatedly bending can obtain the shape of needs several times.Because bending roller 1 and bending roller 29 all can Free-rollings, the part after therefore can effectively preventing bending there is impression.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
