Description
Technical Field
The invention relates to the technical field of metal special-shaped wire forming, in particular to a double-direct-drive roller tractor and a metal special-shaped wire production line.
Background
With the progress of science and technology, the consumption of metal special-shaped wires is continuously increased, and the quality requirement and the performance requirement of users on the metal special-shaped wires are higher and higher. The special-shaped steel wire can meet the quality requirement and the performance requirement of a user on the steel wire, has wide application range, and mainly has the mechanical processing industry, the textile industry, the sealing steel wire rope, the structural steel wire, the nail-making steel wire and the like. For example, the special-shaped metal wire is mainly realized by two ways at present, namely drawing by a special-shaped die and rolling by a passive special-shaped roller. The two forming modes both need a tractor to provide power, and the power is transmitted to a belt pulley and a belt from a motor of the tractor to a speed reducer to a transmission shaft to a traction roller to finally drive the special-shaped metal wire.
As for a traction machine, in a traction machine represented by an isodynamic traction (tensioning) traction rope traction device capable of withdrawing a rope disclosed in chinese patent publication No. CN109987535A (publication date of 2019, 7/9), the following traction driving methods are mainly used in the prior art: single motor, single roller and single drive; the double-roller double-drive single motor adopts double rollers which are connected by a chain; the single motor and the double rollers are driven singly, the motor only drives one roller, and the other roller is driven. When the motor is driven by a single roller, the wires are completely wrapped on the roller, and the heat dissipation is poor; the flat cables are densely arranged, the forming material is discharged before the rear forming material is extruded, and the wires are easy to be transversely scratched; the wire outlet mode is extrusion, so that wire clamping is easily caused; only simple special-shaped wires can be produced, and complex special-shaped wires cannot be produced; the equipment inevitably causes the defects of wire distortion and deformation and the like. When a single motor and double rollers are adopted for double driving, the double rollers are generally subjected to power transmission through a belt or a chain, the chain transmission is often adopted to drive the double rollers, the double rollers are difficult to achieve synchronization at a speed ratio of 1:1, and a wire rod is easy to slip on the rollers to cause longitudinal scratching; the flat cable is forcibly separated by the wire distributor, and the wire is easy to be transversely scratched and deformed. The wire rod is driven by a single motor and double rollers, only one roller is driven by the motor, when the other roller is driven, only one roller is powered, the other roller is driven, and the wire rod is easy to slip on the driven roller to cause longitudinal scratching; the traction force is generated by the static friction force of the contact surface of the power roller and the wire rod, the contact surface of the single-motor double-roller single-drive tractor and the wire rod is only half of double drive, four times of pressure is needed to achieve the same static friction force, the wire rod is easy to deform, the roller is easy to strain, and the like. And the three have the problems of low power efficiency, energy consumption, low production efficiency, high noise and the like because the power is transmitted through the belt or the chain.
In conclusion, the traction machine in the prior art has the defects of unstable traction power and high energy consumption, and further causes the problems of damage to the metal special-shaped wire rod and the like.
