Abstract

The utility model relates to a steel bar binding machine, such as a steel bar binding machine which uses metal wires to crossly bind steel bars which are horizontally and vertically arranged on the building site field, in particular to a metal wire guiding device for the steel bar binding machine, and the size of the circle formation diameter is capable of being adjusted according to the operation conditions. The differences are that a radian regulation module is arranged, the radian regulation module is rotated according to different operation conditions, the shape and an installation angle of an extension groove which is arranged in the guiding device are regulated, thereby controlling the changing of the size of the diameter of a metal wire circle in a certain rang for the operation, and enlarging the selectable space of metal wires.

Description

A kind of reinforcing-bar binding machine wire guides

Technical field

The utility model relates to a kind of reinforcing-bar binding machine, for example the reinforcing bar that will arrange in length and breadth at the scene, building site with wire intersects the reinforcing-bar binding machine of tying up, be particularly related to a kind of reinforcing-bar binding machine wire guides, can become the size of circular diameter to adjust to wire according to the operation situation.

Technical background

In construction work, the reinforcing bar intersection that usually needs to arrange is in length and breadth tied up.Reinforcing-bar binding machine can be described as one on the architectural history and invents greatly, and it has replaced traditional manually tying up, and has alleviated working strength of workers greatly, has improved operating efficiency and bundling quality.

Now common reinforcing-bar binding machine includes main body 1 as shown in Figure 5 on the market, is provided with the ring forming portion of opening at the head of main body, the reinforcing bar 7 that intersects can be placed in one during use; Wire drum 2 can be installed in rear portion in main body.The wire 3 of pulling out from drum is fed to the front portion of this reinforcing-bar binding machine by wire feeder 5, is wrapped on the reinforcing bar of intending tying up 7 along guiding device 6 bendings with arc extension slot.After wire put in place, wire feeder 5 stopped to continue to feed; Structure 8 and the clamping device 4 of tightening in the strapper starts and protracts, and promotes cutting structure and cuts off with being about to wire 3 afterbodys; Clamping device is clamped wire 3 and is rotated, thereby finishes tying up reinforcing bar 7 until tightening wire 3.Whole binding reinforcing bars EP (end of program).

In this reinforcing-bar binding machine, wire 3 bends to circle with certain speed along the guiding device 6 with arc extension slot under the drive of feeder 5, becomes the diameter of a circle size directly related with the shape and the setting angle of the inner extension slot of guiding device.Simultaneously, the thickness of wire 3 changes the size that also directly influences into circular diameter with the change of hardness, and amplitude of variation has bigger difference.In operation, circle is excessive or too smallly may all can't finish the process of tying up.So under the operation situation,, and, require very harsh usually to used selection wiry for the selection of reinforcing-bar binding machine (, can't change) because the shape of the inner extension slot of its guiding device and setting angle are definite.

Summary of the invention

At above-mentioned the deficiencies in the prior art, the utility model provides a kind of reinforcing-bar binding machine wire guides, can be according to different operation situations, shape and setting angle to its inside extension slot are adjusted, thereby the diameter that can control the wire circle within the specific limits changes, make it be fit to this subjob, expanded the space of selecting wiry.

For realizing above-mentioned technical purpose, this utility model adopts following technical scheme, a kind of reinforcing-bar binding machine wire guides, be installed on the supporting walls of reinforcing-bar binding machine body front end, its difference is, include a radian adjustment module, have the arc extension slot on the described radian adjustment module.Can adjust forming diameter wiry (circle diameter) by the position of adjusting the radian adjustment module according to different performance wiry.

For further realizing above-mentioned purpose having two through holes on the described radian adjustment module, one is centre bore, and one is to regulate the waist hole, is installed in by fastening positioning bolt on the supporting walls of body front end.The radian adjustment module can be rotated in the certain angle scope around centre bore.

For further realizing above-mentioned purpose having the radian regulating tank in the outside of described radian adjustment module.

Advantage of the present utility model is, has expanded the space of selecting wiry, can reach desirable circle diameter by the angle of adjusting the radian adjustment module according to different performance wiry.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

Reinforcing-bar binding machine as shown in Figure 1 includes rifle type main body 10, is installed on wire guides 20 on the main body 10 front end supporting walls 11.

Fig. 2 is the structure enlarged drawing of the wire guides among Fig. 1.As shown in Figure 2, described wire guides 20 comprises radian adjustment module 21 and pressing plate module 22, and radian adjustment module 21 backs have wire arc extension slot (not marking) 214, also cries and draws a groove.All have two through holes on radian adjustment module 21 and the pressing plate module 22, and two supporting studs 111,112 are housed on body supports wall 11.By two

fastening positioning bolts

23,24 radian adjustment module 21 and pressing plate module 22 are fitted on the supporting walls 11.

Fig. 3 is the structural representation of radian adjustment module 21 among Fig. 2.

Two through holes on the described radian adjustment module 21, one for the center of circle is decided to be hole 211, and its diameter is identical with supporting studs 111 external diameters on the supporting walls 11, and one for regulating waist hole 212, and its diameter is greater than the external diameter of the supporting studs on the supporting walls 11 112.Have a radian regulating tank 213 in the outside of radian adjustment module 21.

Fig. 4 is the rear view of radian adjustment module 21 shown in Figure 3.Have at radian adjustment module 21 backs and to be provided with width and to draw a groove 214 greater than wire diameter.

The utility model can be adjusted forming diameter wiry (circle diameter) by the position of adjusting the radian adjustment module according to different performance wiry in use.

More than be preferred forms of the present utility model, according to the disclosed content of the utility model, some identical, replacement schemes that those of ordinary skill in the art can expect apparently all should fall into protection domain of the present utility model.
