About Roll Thread Machine Threading Die

What is Roll Thread Rebar threading die?

A rebar threading machine is a precision mechanical device used to cut straight or tapered threads onto the ends of steel reinforcement bars (rebar). A threading die, also known as a chaser, is the specialized cutting tool located within the machine's die head that carves the specific thread profile into the steel. These dies are typically manufactured from high-strength materials such as High-Speed Steel (HSS), particularly grades like M2 or M42, to ensure durability against the hardness of TMT bars.

Why it is Used?

Material Grain Preservation: It does not cut the metal fibers; it compresses them, making the thread 30% stronger than cut threads.
Surface Finish: Produces a mirror-like, smooth finish which reduces friction in rebar couplers.
Speed: It is significantly faster than traditional lathe threading.

Technical Specifcation of Roll thread Rebar Threading die:

Feature	Standard Specification
Rebar Diameter Range	12 mm to 50 mm
Motor Power	3 kW to 7.5 kW (4 HP to 10 HP)
Threading Speed	40 to 62 RPM
Thread Pitch	2.0 mm, 2.5 mm, 3.0 mm, or 4.0 mm
Threading Length	Up to 150 mm or 300 mm (depending on model)
Die Hardness	Typically 60 HRC
Machine Weight	400 kg to 850 kg

Application of Roll Thread :

High-Rise Buildings: Used for vertical reinforcement in core walls and columns to maintain continuous structural strength floor by floor.
Bridges and Flyovers: Employed to prepare high-strength joints for piers, decks, and girders capable of handling heavy dynamic loads.
Metro and Railway Tunnels: Applied for on-site processing of threads for reinforced concrete segments and tunnel linings.
Dams and Power Plants: Used in massive hydro projects where pressure-resistant and leak-proof joints are necessary for safety.

Classification

Circular Dies: Used in two-roll or three-roll cylindrical machines (common for rebar).
Flat Dies: Used in reciprocating machines for bolts and screws.
Planetary Dies: For high-speed mass production of fasteners.

Application

Manufacturing Parallel Thread Rebar Couplers.
Production of Foundation Bolts and Anchor Bolts.
Fastener manufacturing for the automotive and aerospace industries.

Installation

Sleeve Fixation: The plastic sleeve is nailed to the wooden formwork at the mid-depth of the slab.
First Pour: Concrete is poured around the sleeve.
Formwork Removal: The formwork is removed, exposing the sleeve opening.
Plate Insertion: The steel plate is slid into the sleeve before the second slab is poured.

Testing (IS 16172)

Under IS 16172, while the code focuses on mechanical splices (couplers), the Roll Threading Dies used to create the threads and the Dowel Plates used for load transfer must meet specific mechanical requirements:

Tensile Strength: Must match or exceed the parent bar's strength.
Yield Strength: Ensuring no permanent deformation under peak loads.
Hardness Testing: Dies must maintain hardness (usually 58-62 HRC) to withstand repeated rolling.

Since you are a seasoned manufacturer with over 12 years of experience at Surya Engineering, you understand that precision is key. Whether you are supplying Roll Thread Machine Dies for industrial floors, meeting standards like IS 16172 is what sets your brand apart in the Mumbai and PAN India markets.
