Abstract

The invention relates to a cold drawing processing technology of a rocker support rod of a spinning frame. The cold drawing processing technology includes steps of (1) cold drawing of a V-shaped slot for the first time; (2) annealing for the first time; (3) rough drawing of shape for the second time; (4) annealing for the second time; (5) fine drawing of the shape for the third time; (6) straightening; (7) fixed-length milling of a step; (8) hole drilling; (9) chambering; (10) deburring; and (11) surface treating. The cold drawing processing technology of the rocker support rod is simple in steps, high in automation degree, uniform in forming and stable in quality, and adopts special equipment, clamps and tools. Further, the cold-drawn rocker support rod is good in uniformity of an outer circle, and the 100-degree V-shaped slot is good in uniformity, provides the basis for accuracy and flexibility in positions of various components of a drafting part of the spinning frame, and is convenient to match with various rockers. The surface of the cold-drawn rocker support rod can be in various specifications, thereby being convenient to use by users.

Description

technical field [0001] The invention relates to the technical field of forming a cradle rod of a spinning frame, in particular to a cold drawing process of a spinning frame cradle rod. Background technique [0002] The cradle rod is an important supporting part in the drafting part of the spinning frame. It provides the installation foundation and mechanical fulcrum for other key parts in the drafting part. Consistent, high hardness, anti-bending features. These requirements ensure accurate position and stable pressure when the cradle is installed and pressurized. Therefore, the molding quality of the cradle rod directly affects the matching quality of the drafting parts of the spinning frame. At present, the existing processing steps for preparing cradle struts are: sawing material - straightening - punching center hole - turning outer circle - grinding outer circle - milling "V" shaped groove - milling steps with fixed length - Drilling - Reaming - Deburring - Surface t...
