• Cylindrical Thread Rolling Dies

Cylindrical thread rolling dies are specialized tools used for cold forming threads on cylindrical workpieces. They are designed to produce accurate and precise threads on a variety of materials such as steel, aluminum, brass, and copper.

Thread rolling cylindrical dies are typically made of high-speed steel, or other hardened materials to withstand the stresses of the rolling process. They come in various sizes and thread profiles to accommodate different types of workpieces and thread specifications.

Thread Rolling Cylindrical Dies are made for through-feed rolling and in-feed rolling. The thread-turning device is used on a multi-axis automatic lathe to be opposite to the workpiece. The turning device is at right angles to it and moves in this direction to turn the thread. There are usually two roll cones used in one set. The 2 cones are arranged to operate in conjunction like gears. The threaded head is used to make the workpiece clamped at one end eat into the cone, and the thread is made by step rolling. After the processing is completed, the cone is opened and the workpiece can be taken out without reversing. Thread Rolling Cylindrical Dies Applications The cylindrical thread rolling dies are made of high-quality tool steel Cr12MoV, which provides excellent wear resistance and durability. The dies are cylindrical in shape and are available in a wide range of sizes and thread profiles. The dimensions and shape of the dies are determined by the thread diameter and pitch of the workpiece.

We are rolling these threads:Metric thread (M),Trapezoid thread (Tr),Whitworth thread (W, BSF),Unified thread (UN, UNC, UNF, UNJF),Pipe thread (G),Round thread(Rd). Cylindrical thread rolling dies are used in various industries such as automotive, construction, and aerospace for the production of bolts, and studs as well as longer-length threaded pieces.

In feed type thread rolling dies:(Pluge type) In feed thread rolling dies In feed type thread rolling is suitable for thread rolling shorter length. (The thread rolling length is shorter the length of the thread rolling die) Thru feed type thread rolling dies Thru feed type thread rolling is suitable for thread rolling longer length thread rolling. Generally, there are 4 different types of thru feed:

  • Annular ring type
  • Helical slow feed type
  • Continuous rolling type
  • Speed up type
Material Hardness (HRC) Features Applications
D2 55-62 D2 steel is a high-carbon, high-chromium cold work steel, with high hardenability, hardenability, wear resistance, high-temperature oxidation resistance. Used for tensile dies, cold extrusion dies, first punch holder, etc.
Cr12MoV 58-61 Cr12MoV steel is wear-resistant chromium steel, has high hardenability, wear-resistant, small deformation, and affordable price. Used for cold forming dies, common drawing dies, cold heading dies, shear die, cut-off knives.
