T/GDWCA 0039-2018 Technical Specifications for Guide Wheels - General Requirements

Scope

Scope: This section specifies the classification and naming, structure and requirements, finished guide wheel testing requirements, and marking of storage guide wheels, general guide wheels, metering guide wheels, fiber optic cable guide wheels, enameled machine guide wheels, drawing guide wheels, drawing annealing machine guide wheels, line-dividing guide wheels, and other guide wheels (hereinafter referred to as guide wheels). This technical specification applies to guide wheels with a minimum diameter of 5mm to 1500mm, where the diameter of the guide wheels shall include the thickness of the surface treatment layer. Main technical contents: 1. Materials. The materials of the guide wheels include aluminum alloy, plastic, steel, ceramic, and other materials, which shall meet the requirements specified in the appendix of the standard text. 2. Appearance. The surface shall not have obvious sand holes, air holes, shrinkage holes, cracks, and looseness, and the non-processed surface shall not have defects affecting strength. 3. Dimensions and geometric errors. The basic dimensions of the guide wheels shall comply with the design and manufacturing requirements of the manufacturer and the buyer. Other unspecified provisions shall be agreed upon by the manufacturer and the buyer. 4. Surface roughness of the wire-passing groove. The surface roughness of the wire-passing groove of the guide wheels manufactured by mechanical processing methods shall not be lower than Ra1.6 in GB/T 1031, and the surface roughness of the wire-passing groove of the plastic guide wheels molded by injection molding shall not be lower than Ra3.2 in GB/T 1031. The surface roughness of the inner hole of the guide wheel bearing shall not be lower than Ra1.6, and the surface roughness of other unspecified processing surfaces shall not be lower than Ra 6.3 in GB/T 1031. 5. Surface treatment. It can be spray-painting, electroplating, anodic oxidation, tungsten carbide, ceramic spraying, rubber coating
