Detailed description of the invention

Embodiment one:

See Fig. 1, Fig. 2, there is provided a kind of can by the Special hand vice of the bound edge bending 90 ° with right angle flanging, hand vice comprise tong arm 1 and lower tong arm 2, the center of going to the bottom of upper tong arm 1, be provided with the projection 3 of isosceles right triangle, the front end face of upper tong arm 1, concordant with the right-angled apices of projection 3, left and right two waist of projection 3 is respectively A cutting edge 4 and B cutting edge 5; The upper base center of described lower tong arm 2, is provided with the groove 6 of the isosceles right triangle corresponding with projection 3, the front end face of lower tong arm 2, concordant with the right-angled apices of groove 6, two waists of groove 6, are respectively the C cutting edge 7 corresponding with A cutting edge 4, and the D cutting edge 8 corresponding with B cutting edge 5.Groove 6 is enclosed by the wherein both sides of two corner blocks 9 and forms, and two corner blocks 9 are smart steel matter, be connected, be specifically as follows welding with the upper base of lower tong arm 2.Projection 3 is smart steel matter, is connected, is specifically as follows welding with upper going to the bottom of tong arm 1.

See Fig. 1, Fig. 2, Fig. 4, Fig. 5, when processing the bound edge of band right angle, both sides flanging, need bending part first by wherein one right angle flanging, be placed between projection 3 and groove 6, user presses the upper and lower handle of hand vice, A cutting edge 4 coordinates with C cutting edge 7, B cutting edge 5 coordinates with D cutting edge 8, can the disposable gap cutting isosceles right triangle, then needs bending part by relative on another right angle, road flanging, be placed between projection 3 and groove 6, in like manner also disposablely can cut the gap of isosceles right triangle.By bound edge along two opening position bendings, per pass right angle flanging is all equivalent to by two 45° angle splits, bound edge can realize accurate 90 ° of bendings, very attractive in appearance.

See Fig. 1, Fig. 2, Fig. 6, when processing both sides and the bound edge stereogram of centre all with right angle flanging, the same reason, disposablely respectively can need bending part at three right angle, road flangings, cut the gap of isosceles right triangle, then by bound edge along three opening position bendings, bound edge can realize accurate 90 ° of bendings.

See Fig. 1, Fig. 2, Fig. 7, during the bound edge at processing right angle, the same reason, disposablely respectively can need bending part, cut the gap of isosceles right triangle on bound edge both sides, then by bound edge along two opening position bendings, bound edge can realize accurate 90 ° of bendings.

See Fig. 1, Fig. 2, Fig. 8, during the bound edge of processing T font, the same reason, can the disposable right angle flanging in centre need bending part, cut the gap of isosceles right triangle, then by bound edge along this opening position bending, bound edge can realize accurate 90 ° of bendings.

Embodiment two:

See Fig. 3, be only with the difference of embodiment one that the front end face of lower tong arm 2 is connected with the block 10 vertical with lower tong arm 2, the upper surface of block 10, indicates position line 11, position line 11 aligns with the drift angle bisector of projection 3 and groove 6.

See Fig. 3, Fig. 4, Fig. 5, when the bound edge of both sides band right angle flanging described in process embodiment one, the horizontal edge between twice right angle flanging can be made to be close to the inner side of block 10, and hand vice can not occur tiltedly askew, positioning action can be played to each cutting edge, make the gap that cuts more accurate.When after the gap cutting one right angle flanging, when cutting another right angle, road flanging, position line 11 can be made to align the summit of first gap, precise positioning effect can be played to by cut second gap, make it completely relative with first gap, the bending effect of bound edge is better.

See Fig. 3, Fig. 6, when bound edge all with right angle flanging of both sides and centre described in process embodiment one, the twice right angle flanging of both sides can the same reason operation, but one right angle flanging of centre then can only adopt the mode of embodiment one to process.

See Fig. 3, Fig. 7, during the bound edge at right angle described in process embodiment one, also can the same reason operate, two gap can obtain precise positioning, the bending excellent of bound edge.

Above-described embodiment is preferred embodiment of the present utility model, and all structures similar with the utility model and the equivalence done change, and all should belong to protection category of the present utility model.
