Description
Technical field
What the present invention relates to is the reinforcing bar feed mechanism, particularly be a kind of anti-torsion steel bar feed mechanism.
Background technology
At present, various reinforcing bar products in the production and processing building industry, usually need to carry out deep processing in the process equipment being transported to again behind the raw material wire rod wire rod reinforcement metal straightening, before the wire rod reinforcing bar is delivered to deep processing equipment, the wire rod reinforcing bar need to be carried through haulage gear, by bar straightening mechanism moment reinforcement is processed into the vertical bar reinforcing bar again.
The haulage gear of prior art comprises: connect the main drive wheel and the pinch roller that is positioned at the main drive wheel top of motor, the wire rod reinforcing bar utilizes frictional force to be pulled movement between main drive wheel and pinch roller.For improving prior art reinforcing bar propulsive efficiency, once process simultaneously two wire rod reinforcing bars.Along with the development of construction demand, in order to improve reinforcing bar adhesive force in xoncrete structure, building industry adopts the wire rod reinforcing bar of hot-rolled ribbed grade III steel muscle instead of optical circle, and namely the Ribbed Bar surface distributed has fin, and it is oval that its cross section is.
Adopt the prior art steel bar traction mechanism, bar straightening mechanism carries the straightening Ribbed Bar to have following defective: at first, when two Ribbed Bar are passed between the main drive wheel of haulage gear and the pinch roller simultaneously, because the Ribbed Bar cross section is oval, two reinforcing bar cross sectional shapes that enter simultaneously between main drive wheel and the pinch roller there are differences, same pinch roller can not be pressed on two reinforcing bars simultaneously, it is inconsistent that existence is pressed in two pressure on the reinforcing bar, when increasing the pinch roller thrust simultaneously, can make wherein excessive rebar surface that weighs wounded of reinforcing bar pressure, rolling and skidding appear reversing in the reinforcing bar that pressure is little, and the prior art pressing wheel mechanism is difficult to guarantee that two reinforcing bars obtain uniform and stable compression driving force simultaneously.Secondly, the feed mechanism of prior art adopts a corresponding depress wheel above the main drive wheel, and reinforcing bar passes through from the tangential direction of main drive wheel and depress wheel, and the contact area of reinforcing bar and driving wheel is little, and the little hauling speed of frictional force is slow.Have, the direction of advance that is pulled reinforcing bar is a straight line again, and rotation easily occurs in sending process to, exists crooked stirrup out because reinforcing bar reversing in sending process to caused the not deformation defect in a plane of several limits.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned technology, provide a kind of reinforcing bar that is transferred to send to along circular arc path, strengthen main drive wheel and reinforcing bar contact area, reduce pinch roller to rebar surface pressure, pinch roller connects fine setting elasticity screw-down, so that every reinforcing bar all obtains the thrust that is fit to, guarantee many reinforcing bars send to simultaneously do not occur to skid, the asynchronous and anti-a kind of anti-torsion steel bar feed mechanism that reverses.
The technical scheme that solves the problems of the technologies described above is: a kind of anti-torsion steel bar feed mechanism, described a kind of anti-torsion steel bar feed mechanism comprises: frame, be arranged on two aligning wheels of haulage gear on the frame and structure same position symmetry, described haulage gear is arranged between two aligning wheels, and its position is higher than two aligning wheels that are positioned at both sides; Described haulage gear comprises: main drive wheel and the pinch roller that is positioned at the main drive wheel top; Be provided with the V-type groove of traction reinforcing bar on the described main drive wheel outer rim, main drive wheel one end connects rotating power source, and rotating power source is supported on the frame; Described pinch roller cross section outer rim is cambered outwards ladder type, and pinch roller is arranged on the screw-down of adjusting its position, and described screw-down is arranged on the frame; Described two aligning wheels comprise respectively: a plurality of aligning wheels and aligning wheel are depressed mechanism; It is curved that described a plurality of aligning wheel will wrap on main drive wheel trailed Rebar, and described pinch roller is pressed on the V-type groove arc reinforcing bar of main drive wheel.
The invention has the beneficial effects as follows: the present invention overcomes above-mentioned the deficiencies in the prior art, at first, what reinforcing bar of the present invention was walked between main drive wheel and aligning wheels is circular arc path, reinforcing bar forms arc surface with main drive wheel and contacts, strengthen reinforcing bar and main drive wheel and compressed contact area, reinforcing bar is not easy to occur reversing of self in the process that is sent to, traction effect is good.Secondly, special grooved on main drive wheel and the pinch roller can fasten reinforcing bar in the V-type groove, and the assurance reinforcing bar can be fixed a cross section and not twist, prevent that reinforcing bar from occurring skidding, hinder rib, reverse in distraction procedure, nonsynchronous defective, improve finished product reinforcing bar quality.Have, pinch roller is pressed in and prevents on the arcwall face of reinforcing bar that pinch roller to the weighing wounded of Ribbed Bar face rib, can reach perfect condition so that compress the crush of every reinforcing bar again, and the synchronism of many reinforcing bars is good.At last, the whole screw-down of the present invention and independent fine setting elasticity screw-down, adjust in can be at one time several bars synchronously, the charging coordinated, to so that can be unanimously synchronous being sent to of reinforcing bar, and be not subjected to separately cross section differentia influence.The present invention is simple in structure, and is easy to maintenance.
