Description

Wire forming bending tool

Technical field

The utility model relates to wire forming device, particularly relates to wire forming bending tool.

Background technology

For wire rods such as automobile chair frames, in its bending forming process, need to use wire rod bending forming machine to carry out bending produce.Particularly, for wire product as shown in Figures 1 to 3, wire rod is after the bending tool (as shown in Figure 4) that end of incoming cables enters bending forming machine, bending process will be carried out successively to position 1,2,3,4,5, but when producing to position 5, leading-out terminal will be blocked in front end bending part 1,2, namely interfere, and cause cannot continuing to produce.If solve this stop interference problem with additive method, then when continuing the position A that bending is produced as shown in Figure 5, the knuckle head that position A is bent again frock stops, again causes continuing bending and produces; And position 3 is also very easily turned core stop interference by the knuckle of the circle of bending tool.The existing method overcome the above problems is, is retained by position B as shown in Figure 6 and does not first bend production, then completed by manual knuckle.

Still there is following defect in existing bending method above: bending operation is loaded down with trivial details, and need manual knuckle supplement production, causes unstable product quality.

Utility model content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide wire forming bending tool, and it effectively prevents from interfering the stop of wire product in bending production process, and the stable bending realizing wire product is produced.

Utility model

The purpose of this utility model realizes by the following technical solutions:

Wire forming bending tool, comprise knuckle and turn core and be located at the knuckle head that knuckle turns core side, knuckle turns the first knuckle post that core comprises flap and protruded by the plate face of flap, and the middle part of flap has the installing hole with outside rotary power unit synchronized links; First knuckle post forms one group between two, and often organizes the spaced gap forming confession wire product and pass of the first knuckle post, and the two ends of flap are arranged with two group of first knuckle post; The both sides of flap are divided into the straight relief portion be parallel to each other, and the two ends of two straight relief portion and flap enclose formation rectangular shape; The second knuckle post that knuckle head comprises base and protruded by the top of base, the second knuckle post is divided into the both sides of base top, and the two side portions of base is set to the inclination relief portion narrowed gradually from top to bottom.

Preferably, the two ends of flap are set to the arcuate shape of outer arch.

Compared to existing technology, the beneficial effects of the utility model are:

(1) the shaping bending method of wire product is changed by wire forming knuckle frock of the present utility model, solve the production process of half mechanical semi-hand in prior art, the quality of product is made to be more conducive to keep stable, more crucially be, the straight relief portion of flap makes flap form approximate rectangular shape, make the leading section of wire product, rearward end can effectively prevent from the edge turning core with knuckle from producing stopping interfering, and the relief portion that tilts makes base form approximate del, also the leading section of wire product and rearward end and knuckle head can be avoided to interfere the problem of stop, thus be beneficial to the continuous prodution of wire product bending, and, owing to eliminating hand process, also production efficiency is improved.

Detailed description of the invention

Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:

Wire forming bending tool as shown in Fig. 7 ~ 8, comprise knuckle turn core 10 and be located at the knuckle head 20 that knuckle turns core 10 side, knuckle turns the first knuckle post 12 that core 10 comprises flap 11 and protruded by the plate face of flap 11, and the middle part of flap 11 has the installing hole 13 with outside rotary power unit synchronized links; First knuckle post 12 forms one group between two, and often organizes the spaced gap forming confession wire product 30 and pass of the first knuckle post 12, and the two ends of flap 11 are arranged with two group of first knuckle post 12; The both sides of flap 11 are divided into the straight relief portion 14 of the straight relief portion 14, two be parallel to each other and enclose formation rectangular shape with the two ends of flap; Knuckle head 20 comprises base 21 and the second knuckle post 22, second knuckle post 22 of being protruded by the top of base 21 is divided into the both sides at base 21 top, and the two side portions of base 21 is set to the inclination relief portion 23 narrowed gradually from top to bottom.

The shaping bending method of wire product 30 is changed by wire forming knuckle frock, solve the production process of half mechanical semi-hand in prior art, the quality of product is made to be more conducive to keep stable, more crucially be, the straight relief portion 14 of flap 11 makes flap 11 form approximate rectangular shape, make the leading section of wire product 30, rearward end (i.e. position 3a as shown in Figure 7 or position 5a) can effectively prevent from the edge turning core 10 with knuckle from producing stopping interfering, and the relief portion 23 that tilts makes base form approximate del, also the leading section of wire product 30 and rearward end (namely position A ＇) as shown in Figure 8 can be avoided to interfere the problem of stop with knuckle head 20, thus be beneficial to the continuous prodution of wire product 30 bending, and, owing to eliminating hand process, also production efficiency is improved.Wherein, under the rotary power unit effect of bending forming machine, drive knuckle to turn core 10 and rotate; The flap 11 of rectangular shape is beneficial to and reduces to greatest extent to occur to stop the probability of interfering with wire product 30, and for reducing this probability further, the two ends of flap 11 are set to the arcuate shape of outer arch.

Adopt the bending method of above-mentioned wire forming bending tool, comprise the following steps:

S1, wire product 30 is penetrated in the gap of two group of first knuckle post 12;

S2, turn core 10 bend (as shown in Figure 7 to the leading section of wire product 30 and rearward end successively by rotating knuckle, carry out the bending of position 1a, 2a, 3a, 5a, 6a, 7a), it is spacing that the second knuckle post 22 of knuckle head 20 carries out stop to the leading section of wire product 30 and the bending part of rearward end successively;

S3, reversion knuckle turn core 10, in the gap making the middle part of wire product 30 return the first knuckle post 12 (as shown in Figure 7, carry out the bending of position 4a), and under the position-limiting action of the second knuckle post 22 of knuckle head 20, bend this be positioned at kink in the middle part of wire product 30.

First bending forming is carried out to the leading section of wire product 30 and the bending part of rearward end, core 10 is turned again by upset knuckle, in the gap that the middle part of wire product 30 is back between two first knuckle posts 12, bend under the auxiliary stopper effect of knuckle head 20, the oneself not only avoiding self leading section of wire product 30 and rearward end stops interference, manual procedure can also be saved, make wire product 30 one-shot forming, therefore quality is more stable, finally forms the wire product 30 shown in Fig. 1 ~ 3.

To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
