Self-tapping Thread Rolling Die Rethreading Dies

 
The working principle of self-tapping thread rolling dies is mainly through the cold extrusion moulding, the screw light nail extrusion moulding for thread. Its teeth are usually shaped by cold rolling with needle rollers, which can withstand severe impact loads and extrusion stresses after heat treatment. This processing method makes the thread rolling dies in the high production efficiency, low processing costs at the same time, can also ensure the quality of the processed thread.
In industrial applications, thread rolling dies are mainly used in screw factories and bolt processing factories for the threading of a large number of small bolts. As technology continues to advance, thread rolling dies are constantly being improved to meet the needs of more specialized applications.

Materials: Stainless Steel and Alloy Steel


Our thread rolling dies are crafted from premium materials, including stainless steel and alloy steel, each selected for their unique properties to meet diverse industrial requirements.


  1. Stainless Steel Thread Rolling Dies: These dies are specifically engineered for screw factories that produce stainless steel screws. Unlike standard steel thread rolling dies, they undergo a distinct material selection and heat treatment process. This makes them ideal for manufacturing screws with specialized requirements, such as high strength, rust resistance, wear resistance, and the ability to withstand acid and alkali corrosion.


  2. Alloy Steel Thread Rolling Dies: Primarily utilized for the production of standard screws, these dies are renowned for their high hardness and exceptional wear resistance. They are designed to fulfill the general industrial demands for robust and durable fasteners.


By utilizing these high-grade materials, our thread rolling dies ensure optimal performance and longevity, catering to both specialized and general industrial applications.

Thread Rolling Plate Production Process


The manufacturing process for thread rolling plates is a meticulously engineered sequence designed to ensure the highest quality and performance. The detailed production route includes the following steps:


  1. Undercutting: This initial stage involves the removal of excess material to prepare the workpiece for subsequent processes.

  2. Forging: The material is then shaped through forging, a process that strengthens the metal by consolidating its internal structure.

  3. Spheroidal Annealing: This heat treatment process is employed to soften the material, making it more workable for the next stages and improving its machinability.

  4. Machining: Precision machining is carried out to achieve the desired dimensions and tolerances, ensuring that each component meets exacting specifications.

  5. Cold Rolling Threads: Threads are formed through cold rolling, a technique that enhances the strength and surface finish of the threads without removing material.

  6. Hardening and Low-Temperature Tempering: The components undergo a combination of hardening and low-temperature tempering to achieve the desired hardness and toughness, ensuring durability and resistance to wear.

  7. Grinding Process: The final stage involves precision grinding to refine the surface finish and achieve the exact dimensional accuracy required for the thread rolling plates.


Each step in this production route is critical to the final quality of the thread rolling plates, ensuring that they are capable of producing high-quality threads with precision and consistency.
