1. Track: 28 # H shaped steel is machined and installed with 40 40 cold-drawn square steel, which improves the track installation accuracy and ensures the stability of the traction car, thus ensuring the quality of aluminum.

2. Traction car: all parts are machined and manufactured to ensure the machining accuracy of each part, improve the manufacturing accuracy of the whole machine, and improve the reliability and accuracy of car operation; Mechanical buffering device is installed to avoid accidental shock failure.

3. Clamping mechanism: the pallet is raised at 90 degrees to ensure that the return journey does not scratch aluminum. The design of the pressing curve makes the self-locking pressure reliable. At the same time more convenient maintenance management.

4. Traction power: special frequency conversion motor is used to improve the controllability of speed and tension; The constant torque output of frequency converter is used to achieve the purpose of constant tension traction. Two speed regulation to improve the control performance of the tractor return speed, reduce the return stroke fault.

5. Traction device: use chain to drag the traction trolley to improve the stability of traction tension and avoid the possibility of wire rope slipping.

6, brake: dc brake, brake more stable, at the same time do not use mechanical brake, there is no problem with the life of the brake, reduce the fault parts, more convenient maintenance management.

7, display: use the man-machine interface to display the main parameters, information, such as traction length, speed, etc., to facilitate the timely adjustment of the length of aluminum rod, improve the product yield, and more convenient for maintenance and management.

8. Control: manual and automatic control, coordinated operation with interruption of saw, main machine and sliding stage, improved the degree of automation and reduced labor intensity.
