Drill Rod Upsetting Machine

The core forming unit of the drill pipe upsetting production line, dedicated to the end-upsetting (thickening) operation of oil drilling pipe bodies. Driven by a high-tonnage hydraulic system, it applies stable and precisely controlled axial force to the pre-heated pipe end, inducing controlled plastic deformation to produce a uniformly thickened upset zone that meets the strength and dimensional requirements of drill pipe tool joints.

The hydraulic system employs high-precision servo control for smooth pressure output and accurate stroke positioning. Upsetting pressure, speed, and stroke parameters can be flexibly set for different pipe specifications, ensuring consistent deformation volume and forming dimensions across every cycle — effectively preventing wall thickness deviation or end cracking caused by unstable force control.
Forming dies are manufactured from high-strength, heat-resistant alloy materials with excellent wear resistance and thermal fatigue performance. Tight dimensional tolerances on the die cavity enable precise control of the inner and outer diameters and transition geometry of the upset end, supporting internal upset, external upset, and combined internal-external upset process configurations, with straightforward die changeover.
The machine features a highly rigid structure with minimal deflection under maximum upsetting load, ensuring strong repeatability of upset dimensions across every pipe. An integrated clamping and positioning mechanism firmly secures the pipe body throughout the forming stroke, preventing workpiece displacement and maintaining consistent forming quality.
The intuitive operator interface supports digital storage and recall of process parameters, with multi-specification presets enabling fast product changeover without complex re-setup.
 Comprehensive safety protection systems ensure reliable and safe operation, and the machine integrates seamlessly into fully automated production lines for continuous unmanned operation.
