AI Technical Summary
The belt tensioning device of the existing cold heading machine requires a large space when adjusting the tension, which makes the belt wear easy and affects its service life.
The structure uses a hydraulic cylinder to drive the tensioning wheel to extend and retract, reducing the space required for tensioning and avoiding belt friction. The design of support rods and stabilizer rods ensures operational stability.
It effectively reduces belt friction loss, extends belt service life, and improves equipment operational stability.
