Abstract

The invention discloses a servo drive traction machine. The servo drive traction machine comprises a machine frame, an electric box, an operation box and a transmission mechanism, wherein the electricbox is arranged on the machine frame. The transmission mechanism comprises a linear polish rod, a screw rod, an opening and closing servo motor, an upper side traction device, a lower side traction device, a driving servo motor and a reduction gearbox, wherein the linear polish rod is connected with the upper side traction device and the lower side traction device through a linear bearing, the opening and closing servo motor is connected with the screw rod, the lower side traction device and the lower side traction device are installed on the side part of the screw rod through a nut and a nutseat, an air cylinder is further connected between the lower side traction device and the nut seat, and the air cylinder is driven by the opening and closing servo motor to provide the transaction opening and closing power for the upper side traction device and the lower side traction device. A belt pulley of the upper side traction device and a belt pulley of the lower side traction device provide the driving power by the driving servo motor and the reduction gearbox, the belt pulleys drive belts to carry out traction, and guide mechanisms are further arranged at the two ends of the upper side traction device and the lower side traction device. According to the servo drive traction machine, the clamping pressure is conveniently adjusted, the constant clamping force can be provided, and the stable wire production speed can be provided.

Description

technical field

[0001] The invention belongs to the technical field of mechanical devices, and belongs to traction equipment for extrusion production lines of pipe products, in particular to a servo-driven traction machine. Background technique

[0002] With the rapid development of the domestic economy, especially the rapid development of the automobile industry and high-speed rail, rubber hoses have become an indispensable material in daily life and industrial development. In the production process of rubber hose extrusion, the traction equipment is very important. It must not only ensure that the product is not crushed during the production process, but also ensure that it can provide sufficient and stable traction. The clamping of the existing equipment is often adjusted by the hand handle, the clamping force is difficult to adjust and quantify, and the speed of the production line is unstable, especially in the initial stage of production line start-up and speed-up, and...
