Technical background

For a long time, the steel wire newly curved for needs all is that steel wire is placed on the working face that locating shaft is housed, and turns an angle along locating shaft, is bent into required shape.But owing to be subjected to condition restriction, steel wire can only be converted into simple shape.As steel wire will being converted into complicated shape, or repeatedly angle bending is not or not same plane, and not only time-consuming taking a lot of work can't guarantee that the shape that bending goes out is unified, so the quality of bending can not get guaranteeing.

Summary of the invention

For overcoming the existing in prior technology problem, the utility model provides a kind of repeatedly bender, and it can be bent into various complicated shapes by desired angle with steel wire, and not only the shape of bending is unified, and bending efficient increases substantially.

The technical scheme in the invention for solving the technical problem is: above-mentioned repeatedly bender comprises frame, be packed in the supporting plate of frame one side, supporting plate is equipped with the steady pin on outstanding its plane, difference is, above-mentioned frame opposite side is equipped with rotating shaft, shaft set has rotating rotor plate, one side of rotor plate is equipped with handle, but the die change that is used to limit steel wire bending position and size is housed on the rotor plate, but die change has the straight groove of placing steel wire, leave the interval of placing steel wire between the port of straight groove one end and the said fixing pin, straight groove one side extension line and steady pin external cylindrical surface are tangent, in the straight groove or its place of extending axially is equipped with projection against the retaining platform, and straight groove one or both sides have the second perpendicular groove.

Be equipped with the height shelves on above-mentioned second groove, be used to shelve the steel wire of bending, steel wire and horizontal plane constitute angle α, if steel wire is continued bending, steel wire are put pavilion on shelves, steel wire can be converted into required bending angle.

But above-mentioned die change is made up of first mould and second mould, and first mould and second mould are fitted and be packed on the above-mentioned rotor plate.

But straight groove port one side has wear-resistant block on the above-mentioned die change, and this wear-resistant block adopts black steel hard material, can prevent that straight groove port from wearing and tearing fast at its bending part, but prolongs die change service life.

Above-mentioned supporting plate and rotor plate are positioned at same plane, and above-mentioned supporting plate is equipped with block, are used to place restrictions on the rotor plate anglec of rotation.

Above-mentioned supporting plate is equipped with the plastics supporting plate, and above-mentioned rotor plate is equipped with the plastic rotary plate, adopts plastics to help the skin sparing of hand.

It is as follows that repeatedly bender of the present utility model has advantage compared with prior art: but the die change of this bender is arranged on the rotor plate, and but the one side extension line of the straight groove on the die change and steady pin external cylindrical surface are tangent, in the straight groove or its place of extending axially is equipped with projection against the retaining platform, straight groove one or both sides have the second perpendicular groove, be equipped with the height shelves on above-mentioned second groove, steel wire can be bent into various complicated shapes by desired angle, not only the shape of bending is unified, and bending efficient increases substantially; Secondly, but the die change of this bender form by first mould and second mould, its discrete mould is not only easy to make, but and can obtain various required die changes by the first different moulds and second die combination.

The specific embodiment

Below in conjunction with drawings and Examples repeatedly bender of the present utility model is described further.

As Figure 1-3, above-mentioned repeatedly bender comprises frame 1, be packed in the supporting plate 2 of frame 1 one sides, supporting plate 2 is equipped with the steady pin 21 on outstanding its plane, difference is, above-mentioned frame 1 opposite side is equipped with rotating shaft 11, rotating shaft 11 is set with rotating rotor plate 3, one side of rotor plate 3 is equipped with handle 31, but the die change 4 that is used to limit steel wire bending position and size is housed on the rotor plate 3, but die change 4 has the straight groove 41 of placing steel wire, leave the interval of placing steel wire between the port of straight groove 41 1 ends and the said fixing pin 21, straight groove 41 1 side extension lines and steady pin 21 external cylindrical surfaces are tangent, in the straight groove 41 or its place of extending axially is equipped with projection against retaining platform 41a, and straight groove 41 one or both sides have perpendicular second groove, 42, the second grooves 42 and artificially set according to required bending position in straight groove 41 positions.Be equipped with height shelves 42a on above-mentioned second groove 42.Shown in Fig. 4-8, but above-mentioned die change 4 is made up of the first mould 4a and the second mould 4b, its discrete Mold Making is convenient, the first mould 4a can make the mould of first kind of form or second kind of form or the third form easily, the second mould 4b can make the mould of first kind of form or second kind of form easily, but and can obtain required various die changes by the different first mould 4a and second mould 4b combination, the first mould 4a and the second mould 4b can fit and be packed on the above-mentioned rotor plate 3.But straight groove 41 ports one side has wear-resistant block 41b on the above-mentioned die change 4.Above-mentioned supporting plate 2 is positioned at same plane with rotor plate 3, and above-mentioned supporting plate 2 is equipped with block 22.Above-mentioned supporting plate 2 is equipped with plastics supporting plate 23, and above-mentioned rotor plate 3 is equipped with plastic rotary plate 32.
