The technical problems to be solved in the utility model: wire is in Bending Processing, and wire has very large damage, and working (machining) efficiency is very low.

For solving the problems of the technologies described above, the utility model proposes a kind of special-purpose wire bending jig being arranged on mould bases, concrete technical scheme is as follows:

A wire bending jig, described tool is arranged on a mould bases, comprises wire positioning seat, wire pressing block and bending tool; Described mould bases comprises lower bolster, cope match-plate pattern and guide pillar; Described wire positioning seat is positioned on described lower bolster, and its upper surface is provided with the groove of placing described wire; Described wire pressing block and described bending tool are arranged on described cope match-plate pattern, and can follow described cope match-plate pattern and move up and down along described guide pillar, and its position is corresponding with described wire positioning seat.

Preferably, described lower bolster is provided with guide rail and limited post, and described guide rail limits the position, left and right of described wire positioning seat, and described limited post limits the front and back position of described wire positioning seat.

Preferably, described guide rail is two rectangular metal pieces that are parallel to each other, and its trend is fore-and-aft direction, and the width of the spacing of described guide rail and described wire positioning seat matches.

Preferably, described limited post is located in described guide rail.

Preferably, described cope match-plate pattern is provided with a screw, and the screw portion of described screw spins through described cope match-plate pattern and described wire pressing block.

Preferably, between described wire pressing block and described cope match-plate pattern, be also provided with Compress Spring, described Compress Spring is sleeved on the screw rod of described screw.

Preferably, described wire positioning seat is also equipped with a feeding handle.

Preferably, the quantity of described wire positioning seat is greater than 1.

Preferably, described bending tool is strip, and front and back respectively have 1, and itself and described wire contact position are provided with an arc surface.

By technique scheme, the utility model is provided with wire positioning seat, wire pressing block and bending tool on mould bases, and detailed process is: wire is put into wire positioning seat, and wire pressing block is pushed down in the middle of wire, and bending tool is by the bending of wire two ends.Because cope match-plate pattern moving up and down on guide pillar is more steady, and the machined surface of bending tool is an arc surface, so the damage of wire is less, then because the quantity of wire positioning seat has a plurality ofly, material loading and processing can be carried out simultaneously, so efficiency is higher.

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1, Figure 2 and Figure 3, a kind of wire bending jig, is arranged on a mould bases, comprises wire positioning seat 1, wire pressing block 2 and bending tool 3.Mould bases comprises lower bolster 4, cope match-plate pattern 5 and guide pillar 6, and wire positioning seat 1 is positioned on lower bolster 4, and its upper surface is provided with the groove of placing wire 10.Wire pressing block 2 and bending tool 3 are arranged on cope match-plate pattern 5, and can follow cope match-plate pattern 5 and move up and down along guide pillar 6, and its position is corresponding with wire positioning seat 1.

Lower bolster 4 is provided with guide rail 41 and limited post 42, the position, left and right of guide rail 41 restriction wire positioning seats 1, the front and back position of limited post 42 restriction wire positioning seats 1.Guide rail is two rectangular metal pieces that are parallel to each other, and for operator, the trend of guide rail 41 is fore-and-aft direction, and the width of the distance of two guide rails 41 and wire positioning seat 1 matches.Limited post 42 is located in guide rail 41, and from operator, in the back, its position is to coordinate bending tool 3 above and wire pressing block 2 to limited post 42.Briefly namely wire positioning seat 1 can move from front to back along guide rail 41, moves to limited post 42 places and stops moving, and its position bending tool 3 and wire pressing block 2 just and is above corresponding.

Persons of ordinary skill in the art may appreciate that the above-mentioned localization method to wire positioning seat 1 has a variety of, as alignment pin etc., at this, do not limit.

Between wire pressing block 2 and cope match-plate pattern 5, by screw 7, be connected.Cope match-plate pattern 5 is provided with a through hole, and wire pressing block 2 is provided with screwed hole, and the screw portion of screw 7 is screwed onto wire pressing block through through hole, and wire pressing block has just connected together with cope match-plate pattern 5 like this.In order to guarantee that 2 of line balls have pressure to impose on wire 10 all the time, between wire pressing block 2 and cope match-plate pattern 5, be also provided with Compress Spring 8, Compress Spring 8 is sleeved on the screw rod of screw 7.When wire pressing block 2 compresses wire 10, Compress Spring 9 is in compressive state.

Persons of ordinary skill in the art may appreciate that method that above-mentioned wire pressing block 2 is connected with cope match-plate pattern 5 has a variety of, whether need to add Compress Spring in centre, also can determine according to the situation of concrete scheme, at this, do not limit.

For the ease of the seat 1 that positions the wire, along guide rail, deliver to bending tool 3 times, wire positioning seat 1 is equipped with a feeding handle 9.Feeding handle 9 connects 7 by screw and receives wire positioning seat 1, and for lightly, the material of feeding handle 9 is aluminium alloy.

In order to raise the efficiency, the quantity of wire positioning seat 1 has a lot of, and like this, material loading and processing can be carried out simultaneously.

Bending tool 3 is strip, and front and back respectively have 1, and itself and wire 10 contact positions are provided with an arc surface.Arc surface can effectively be avoided the damage of 3 pairs of wires 10 of bending tool.In order to improve the service life of bending tool 3, the material of bending tool 3 is mould steel Cr12, and surface is also made hard chrome plating and processed.Hard chrome plating not only makes bending tool 3 case hardnesses improve, not easy to wear, and has greatly improved surface roughness, has further reduced the injury of 3 pairs of wires 10 of bending tool.

By the explanation of above-described embodiment, the utility model is provided with wire positioning seat, wire pressing block and bending tool on mould bases, and detailed process is: wire is put into wire positioning seat, and wire pressing block is pushed down in the middle of wire, and bending tool is by the bending of wire two ends.Because cope match-plate pattern moving up and down on guide pillar is more steady, and the machined surface of bending tool is an arc surface, so the damage of wire is less, then because the quantity of wire positioning seat has a plurality ofly, material loading and processing can be carried out simultaneously, so efficiency is higher.

Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
