Product Description

Core Special Accessories for Prestressed Steel Bar Processing & Rebar Splicing Solutions

Rebar Upsetting Machine Pier Head - High-Strength

Product Overview

Rebar upsetting machine pier head (also known as upsetting die / heading die) is the core forming component of rebar upsetting machines, widely used in prestressed concrete pipe pile production, bridge engineering, high-rise building construction and other infrastructure fields. It is mainly used to perform cold upsetting forming on the ends of PC steel bars, prestressed steel wires and ordinary threaded steel bars, expanding the end cross-section to form a standard pier head, so as to meet the requirements of subsequent tension anchoring, mechanical splicing and thread processing.

Core Functions

End Forming
Forge the end of high-strength steel bar into a uniform, full and coaxial pier head under high hydraulic pressure, ensuring the size meets design standards.
Positioning & Stability
Guarantee accurate centering of steel bar and die cavity, avoid defects such as eccentric pier head, flat head, insufficient material and cracking.
Anchoring & Splicing Foundation
Provide reliable mechanical anchoring structure for prestressed tensioning and high-strength splicing, improving connection strength and structural safety.
Process Adaptability
Support subsequent threading, sleeve connection and tensioning procedures, ensuring smooth matching of the entire processing line.

Key Performance Advantages

High‑grade Material
Adopt forged Cr12MoV cold work die steel, with high hardness, wear resistance and fatigue resistance.
Precision Heat Treatment
Vacuum quenching and tempering, hardness controlled at HRC48–52, balancing hardness and toughness to resist impact and avoid chipping.
High Precision Machining
Cavity finished by precision grinding, coaxiality ≤0.03mm, ensuring stable and consistent pier head size.
Strong Pressure Resistance
Withstand long-term high-pressure upsetting force (50–200kN), no deformation, no cracking, long service life.
Wide Compatibility
Suitable for Φ7.1, Φ9.0, Φ10.7, Φ12.6mm prestressed steel bars and Φ16–40mm threaded steel bars, matching mainstream hydraulic upsetting machines.

Application Scenarios

Prestressed concrete pipe pile steel bar end upsetting
Bridge and high-speed rail rebar mechanical splicing
High-rise building steel bar connection and prestressed anchoring
Prefabricated component steel bar processing production line
