Description
Technical field
The invention belongs to machining technique field, particularly relate to a kind of bar apparatus for bending.
Background technology
Bending for �� less than 10 bar, usually pulls at hand and utilizes simple mould on punch press, bar is carried out bending repeatedly, and school shape just can complete. Also needing bend to be analyzed before bending, if the material of bool has enough plasticity, surrender is than little, and the ratio of yield-point and springform is little, is just conducive to bending forming and ensures the quality of workpiece. Otherwise, bending effect is poor, even cannot bend.
Utilizing simple mould bending, workpiece size precision is low, and the precision at especially U-shaped part right angle is difficult to be ensured. 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 relatively big in the process of bending, making the easy sassafras wound of piece surface, affect accessory appearance quality, the easy resilience of part after bending, it is necessary to pincers worker correction repeatedly, correction difficulty is big.
Therefore, how to solve the problems of the technologies described above the direction becoming these those skilled in the art and making great efforts.
Summary of the invention
It is an object of the invention to provide a kind of bar apparatus for bending, above-mentioned prior art Problems existing can be solved completely.
The object of the present invention is realized by following technical proposals:
A kind of bar apparatus for bending, the bending cutter comprising base and be connected with drive unit, under the effect of drive unit, bending cutter can up and down to-and-fro movement in the vertical direction, base is provided with bending groove, in bending groove, interval arranges two bending rollers one, the surface that bending cutter is arranged between two bending rollers one.
Further, described bending cutter one end is connected with drive unit, and the other end rotating shaft connects bending roller two, establishes grooved hole in the middle part of bending cutter.
Further, on described base, symmetrical installation fixes right baffle-plate and right baffle plate, forms bending groove between left and right baffle plate, and two bending rollers one are arranged in bending groove by rotating shaft.
Further, spacing groove is circumferentially offered on described bending roller one surface.
Further, also comprise stop means, this stop means comprises fixed block, L-shaped preset pieces, screw rod and spring, and described fixed block is fixed on base, offers the bar hole consistent with bending groove bearing of trend on fixed block, L-shaped preset pieces is fixed on bar hole by screw, nut, spring is socketed on screw rod, and screw rod tail end is threaded with L-shaped preset pieces, and is locked by set nut, this screw rod is positioned at above bending groove, and mutually parallel 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 and positions on this inclined-plane, avoids bar transition friction to produce impression.
Compared with prior art, the useful effect of the present invention is: structure is simple, reasonable in design, it is possible to process the U-shaped part of different size and shape, it is possible to 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 quality product, it is to increase 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 �� less than 10 bar.

Embodiment
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 cutter 2 comprising base 1 and be connected with drive unit, the drive unit that the present embodiment adopts is palm punch press, bending cutter 2 is connected with the main shaft of palm punch press, when palm punch press works, bending cutter 2 can to-and-fro movement up and down in the vertical direction. 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, being installed by rotating shaft in bending groove 5 and be spaced a distance between two bending rollers, one 6, two bending rollers 1, spacing groove 7 is circumferentially offered on described bending roller 1 surface. Described bending cutter 2 be arranged between two bending rollers 1 middle part surface, this bending cutter 2 one end is connected with palm punch press, and the other end offers U shape groove hole 8, U shape groove hole 8 end by rotating shaft connection bending roller 29.
In order to locate bar and adapt to different bending sizes, the U-shaped part of bending height, right baffle-plate 3 installs stop means, this stop means comprises fixed block 10, L-shaped preset pieces 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-shaped preset pieces 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-shaped preset pieces 11, and locked by set 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 it is mutually parallel with bending groove 5.
See Fig. 7 to Fig. 9, in use, by screw or pressing plate, the base 1 of this device is fixed on hand pulls on the work table top of punch press, bending cutter 2(is equivalent to punch) it is fixed on hand and pulls on the main shaft of punch press, base 1 is adjusted to suitable position, being placed in the spacing groove 7 of bending roller 1 by bar 17, the cambered surface of spacing groove 7 and the cylindrical surface of bar 17 fit, and the gap between two bending rollers 1 is equivalent to die. Bending size according to part is different highly different with bending, and L-shaped preset pieces 11 can move along the bar hole 14 on fixed block 10, thus regulates the position of screw rod 12, and screw rod 12 coordinates for locating bar 17 and inching with spring 13. The main shaft of palm punch press drives bending cutter 2 to move vertically downward, the gap between bending roller 29 extruded bar stock 17 to two bending rollers 1 of bending cutter 2 end, thus bending bar 17, and repeatedly bending can obtain the shape of needs for several times. Owing to bending roller 1 and bending roller 29 all can freely roll, the part after therefore can effectively preventing bending there is impression.
The foregoing is only the better embodiment of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. done within the spirit and principles in the present invention, all should be included within protection scope of the present invention.
