Linear guide rail cold drawing process

The invention discloses a linear guide rail cold drawing process which comprises the following steps: blank selection; heading: manufacturing a process chuck; an intermediate frequency furnace is used for heating one end of a raw material, a process chuck is manufactured according to the size of the section of a guide rail finished product, and the process chuck needs to be smaller than the minimum section of the guide rail, so that the chuck can smoothly pass through a die hole, clamp the process chuck, draw and generate drawing force. The special drawing equipment and mold are used in the drawing process, the size of the product is accurate, and the surface is smooth and bright; tools and equipment are simple and convenient to maintain; small-specification long products can be continuously produced at a high speed; in the drawing process, high strength and stability of equipment can be kept, abrasion resistance and durability of a die are good, abrasion of a drawing tool and the drawing die can be effective
