Description
Technical Field
The utility model relates to a welding equipment field specifically is an automatic wire drive feed unit of electric welding.
Background
Welding is a mature technology, repair to the defect on metal surface and need adopt the build-up welding to fill, then machining is in order to restore the original size of work piece again, in order to raise the efficiency when the welding volume is great, reduce intensity of labour and generally adopt automatic electric welding, automatic electric welding is automatic to carry the welding wire through wire feeder during operation, the wire feeder of current automatic electric welding generally is through two fixed pinch rollers, the welding wire passes between two pinch rollers, the friction through the pinch roller drives the welding wire and removes, different work pieces probably need use the welding wire of different specifications, consequently need change the pinch roller when changing different welding wires, the operation is inconvenient, and work efficiency is reduced.
Disclosure of Invention
The utility model aims at providing a wire drive feed unit of automatic electric welding machine for solve the wire drive feed unit of current automatic electric welding machine and operate inconveniently when changing the welding wire, reduced work efficiency's problem, provide an automatic electric welding machine.
The utility model has the following concrete scheme: the wire feeding device of the automatic electric welding machine comprises a reduction gearbox, a speed reducing mechanism is arranged in the reduction gearbox, a driving motor is arranged on one side of the reduction gearbox, a driving wheel is arranged at the output end of the reduction gearbox, an elastic pinch roller is arranged on one side of the driving wheel on the outer wall of the reduction gearbox, the elastic pinch roller is matched with the driving wheel and used for conveying welding wires downwards, at least two guide wheels are arranged below the driving wheel and the elastic pinch roller on the outer wall of the reduction gearbox, the welding wires penetrate through a channel between the guide wheels from top to bottom, an L-shaped support is arranged at the bottom of the reduction gearbox, a bottom plate of the L-shaped support faces one side of the guide wheels, and a vertical downward guide pipe is arranged on the bottom plate.
Elasticity pinch roller includes a horizontal pole, and horizontal pole one end bottom is equipped with a Y-shaped support, is equipped with a pinch roller in the Y-shaped support, and a round pin axle is equipped with to the top that lies in the Y-shaped support on the horizontal pole, round pin axle and reducing gear box outer wall fixed connection, and horizontal pole other end bottom is equipped with a pressure spring, and the reducing gear box outer wall is equipped with a boss, pressure spring bottom and boss fixed connection.
The utility model is provided with a welding flux guide tube on one side of the guide tube on the L-shaped bracket.
The utility model discloses the theory of operation as follows: the welding wire passes through a channel between the driving wheel and the pressing wheel from top to bottom, the pressing wheel elastically compresses the welding wire under the action of the pressure spring, the motor drives the driving wheel to rotate through the reduction box, so that the driving wheel and the pressing wheel twist the welding wire downwards through friction force, the welding wire is introduced into the guide pipe through the driving theory and the two guide wheels below the pressing wheel, the welding wire passes through the lower end of the guide pipe to reach the surface of a workpiece, and meanwhile, the welding flux falls onto the welding surface of the workpiece through the welding flux guide pipe, so that submerged-arc welding process operation is realized.
Compared with the prior art, the utility model has the following advantages: set up the elasticity pinch roller, when trading the welding wire, need not change the pinch roller, the pinch roller compresses tightly the welding wire automatically through the effect of pressure spring to improve work efficiency.
