Technical field
What the present invention relates to is steel bar traction mechanism, particularly be three slot type traction wheels in steel bar traction mechanism.
Technical background
Along with economic construction is fast-developing, automation screwing steel bars equipment is widely used, be unable to do without steel bar traction mechanism in automation screwing steel bars equipment, the effect of haulage gear is that the reinforcing bar after driving aligning moves forward, for next step screwing steel bars is carried.
Steel bar traction mechanism of the prior art comprises: the axis of traction be connected with motor, axis of traction installs traction wheel, above traction wheel, is provided with contact roller, and described contact roller is arranged on hold-down mechanism.In work, hold-down mechanism drives contact roller that reinforcing bar is pressed on traction wheel, and when driven by motor axis of traction rotates, traction wheel rotates thereupon, and under the effect of frictional force, traction wheel rotates and drives reinforcing bar reach, realizes traction reinforcing bar.
The traction wheel outer rim of prior art is designed to single arc groove with the contact surface of reinforcing bar or singlely rises as high as the banks, and in traction reinforcing bar process, is improve working (machining) efficiency, selects small diameter reinforcing bar two to draw, the single traction of larger diameter reinforcing bar simultaneously.The traction wheel of rising as high as the banks as single is when drawing single steel bar, and because traction wheel will bear very large frictional force and impulsive force, use for a long time, single steel bar produces one polishing scratch in traction wheel is risen as high as the banks; When still use above-mentioned single traction wheel of rising as high as the banks lead at the same time draw two reinforcing bars time, in one polishing scratch that wherein reinforcing bar must be absorbed in being worn, and another root reinforcing bar is pulled on unworn, there will be the inconsistent phenomenon of contact surface of two reinforcing bars and traction wheel, trailed two reinforcing bars occur asynchronous, cause the two inconsistent defects of reinforcing bar length produced.Namely, on same single arc groove or single traction wheel of rising as high as the banks, when single steel bar, bi-steel are alternately drawn in front and back, the Wear track depth that the friction of reinforcing bar to traction wheel produces has difference, traction bi-steel there will be the inconsistent phenomenon of contact surface of bi-steel and traction wheel, must occur the defect in reinforcing bar quality after traction.
Summary of the invention
The object of the invention is to the defect overcoming above-mentioned prior art, there is provided a kind of on a traction wheel, be provided with the arc groove of traction bi-steel and the arc groove of traction single steel bar, the bi-steel of traction and the single steel bar of traction are taken their own roads, there is efficiency high, three slot type traction wheels in the steel bar traction mechanism that traction steel bar quality is good.
The technical scheme solved the problems of the technologies described above is: three slot type traction wheels in a kind of steel bar traction mechanism, described three slot type traction wheels are arranged on the axis of traction in steel bar traction mechanism below contact roller, the center mounting hole of described three slot type traction wheels is fitted in axis of traction one end, the wheel hub of three slot type traction wheels has multiple fastening installing hole, and three slot type traction wheels are fixed on the cascaded surface of axis of traction through described fastening installing hole by securing member; The outer rim of three slot type traction wheels has three half-arc grooves be set up in parallel, and described three half-arc grooves and reinforcing bar coincide.
Preferred version is: the structure of described three half-arc grooves is identical.
Preferred version is: two the half-arc groove structures being positioned at outside in described three half-arc grooves are identical.
The invention has the beneficial effects as follows: the present invention overcomes the deficiencies in the prior art, three slot type traction wheels of the present invention can make reinforcing bar be pulled in fixing groove, traction bi-steel (two reinforcing bars) and traction single steel bar (reinforcing bar) are taken their own roads, reinforcing bar is pulled along fixing arc groove, consistent to the traction race arc degree of wear, avoid occurring that traction wheel causes occurring the defect that length is inconsistent during traction reinforcing bar due to the vestige difference that is worn, guarantee to be pulled bi-steel synchronous operation consistent with the length after traction.
