The outer knurling of knurling copper insert nuts has two forming methods, one is to use copper raw material to pull forming, and then production on the equipment, generally this pull pattern is straight line, the other is in the production process of direct tapping of round copper material tooth embossing, this processing method can produce some non-standard size knurling copper nuts, such as straight embossing, twill, mesh embossing, figure 8 embossing, herringbone embossing and so on
Copper knurled insert nut outer knurled pattern is a kind of metal processing technology. The desired tooth profile is distributed on the outside of the nut insert. The outer knurled pattern of the insert is very important and directly affects the torque of the nut. Vertical knurls can provide maximum torque, but the pull force is small, which is increased by the value of the grooves between the knurls. Diagonal or spiral knurls balance resistance in both directions, i.e. balancing tension and torque performance.
Knurled copper nut outer pattern knurled simple, high-speed automatic lathe can be completed in a single time, complex copper nuts plus molding knife processing and table car/tapping machine after processing, many products are relatively simple mesh copper nuts and straight pattern copper nuts, made of C3604, cutting brass, surface pattern for the original rod direct pull, full pattern, tooth peak tooth base clearly visible, Can withstand greater torque after injection molding.
