[0002] Guide rail: A device made of grooves or ridges made of metal or other materials that supports, secures, and guides moving devices or equipment while reducing friction. The longitudinal grooves or ridges on the surface of a guide rail are used to guide and secure machine parts, specialized equipment, and instruments. Guide rails, also known as slide rails, linear guides, and linear slides, are used for linear reciprocating motion. They have higher load ratings than linear bearings and can withstand a certain amount of torque, enabling high-precision linear motion under high loads.

[0003] Due to the actual demand for some wear-resistant guide rails, corresponding bending operations need to be performed. When the existing guide rails are stamped and bent, their tooling lacks limit stops on both sides, which has hidden dangers of movement, resulting in poor bending and poor reliability.
