Traction machine with multiple direct-drive rollers and metal wire production line

Abstract

The invention relates to the technical field of metal wire forming, in particular to a double-direct-drive-roller traction machine and a metal special-shaped wire production line. Compared with the prior art, the double-direct-drive-roller traction machine is provided with a first driving part connected with a first roller and a second driving part connected with a second roller; the first roller and the second roller of the traction machine are directly driven, a transmission device does not need to be additionally arranged between the first roller and the second roller, and the traction machine has high power efficiency, low energy consumption and low noise; the first roller and the second roller have larger winding areas, so that the wire wound on the first roller and the second roller can be endowed with more stable traction force under the same tension, on one hand, the deformation of the wire can be avoided, and on the other hand, the reining damage of the rollers is avoided; and the first roller and the second roller can rotate synchronously by adjusting the speed ratio of the output shafts of the first driving part and the second driving part, and damage caused by sliding friction between the roller surfaces and the wires can be avoided.

Description

technical field [0001] The invention relates to the technical field of forming metal special-shaped wires, in particular to a double direct-drive roller tractor and a metal special-shaped wire production line. Background technique [0002] With the advancement of science and technology, the consumption of special-shaped metal wires is also increasing continuously, and the quality requirements and performance requirements of users for special-shaped metal wires are also getting higher and higher. Among them, special-shaped steel wire can meet the quality requirements and performance requirements of users for steel wire. Special-shaped steel wire is widely used, mainly in machinery processing industry, textile industry, sealing steel wire rope, structural steel wire and nail-making steel wire. For example, special-shaped metal wires are mainly realized in two ways at present, one is special-shaped die drawing, and the other is passive special-shaped roll rolling. Both of thes...

Problems solved by technology

When the motor is single-drum and single-driven, the wire is fully wrapped on the drum, and the heat dissipation is poor; the wire arrangement is densely arranged, and the rear molding material is extruded and the front molding material is discharged, and the wire is easy to be scratched horizontally; because the outlet method is by extrusion It is easy to cause wire clamping; only simple special-shaped wires can be produced, and complex special-shaped wires cannot be produced; the equipment will inevitably cause shortcomings such as twisting and deformation of the wires

When single motor, double drum and double drive are used, the power transmission between the double drums is generally carried out by belts or chains, often with chain transmission, driving the double drums, and the 1:1 speed ratio is difficult to synchronize the two drums, and the wire is easy to be on the drums. Slipping, causing longitudinal scratches; the cables are forcibly separated by the splitter, and the wires are easy to be scratched and deformed horizontally.

Single drive with single motor, double drums, the motor only drives one drum, and when the other drum is passive, only one drum is powered, and the other drum is passive, and the wire is easy to slip on the passive drum, causing longitudinal abrasion; the traction is determined by The static friction of the contact surface between the power roller and the wire is generated. The contact surface between the single motor, double roller and single drive tractor and the wire is only half of that of the double drive. It must use four times the pressure to achieve the same static friction. The wire is easy to deform, and the roller Disadvantages such as easy strangulation

Moreover, the three all have problems such as transmission of power through belts or chains, low power efficiency, energy consumption, low production efficiency, and high noise.

[0004] To sum up, the tractors in the prior art have the disadvantages of unstable traction power and high energy consumption, which in turn will cause problems such as damage to metal special-shaped wires
