Electric Pipe Roll Grooving Machine

Core Functional Capabilities

Hydraulic-Driven Precision Grooving:

· Mechanism: High-force hydraulic cylinder combined with a heavy-duty manual or electric hydraulic pump.

· Function: Delivers smooth, progressive downward force on the upper grooving roll, cold-forming the pipe wall against the lower drive roll.

· Benefit: Ensures uniform groove profiles and prevents pipe wall fracturing or deformation.

Standardized Groove Profile Control:

· Mechanism: Precision depth adjustment gauge and micro-metric limit switch.

· Function: Allows operators to pre-set the precise groove depth according to international piping standards (e.g., AWWA, ASTM).

· Benefit: Guarantees consistency across hundreds of grooved joints, ensuring leak-free coupling fitment.

High-Torque Spindle Drive:

· Mechanism: Low-RPM, high-torque industrial induction motor with a hardened steel gear reduction box.

· Function: Drives the lower knurled shaft to rotate heavy steel pipes under high hydraulic pressure without slipping.

· Benefit: Provides smooth rotation, reducing tool wear and ensuring concentric groove tracking.

 Core Functional Capabilities

High-Torque Multi-Speed Drill Spindle:

· Mechanism: High-output universal or induction motor coupled with a heavy-duty industrial keyed drill chuck.

· Function: Drives industrial hole saws (bi-metal or carbide-tipped) at optimized rotational speeds through thick-walled carbon steel pipes.

· Benefit: Prevents tool bog-down and stalling, resulting in clean, circular holes without jagged edges.

Heavy-Duty Chain Clamping & Alignment System:

· Mechanism: High-tensile alloy steel chain clamp with a quick-tensioning lever and an integrated spirit level (bubble level).

· Function: Secures the machine firmly to any pipe diameter, ensuring the spindle is perfectly perpendicular to the pipe centerline.

· Benefit: Prevents machine oscillation or slipping during drilling, ensuring exact hole positioning and vertical alignment for mechanical tees.

Integrated Feed & Depth Travel Control:

· Mechanism: Ergonomic feed handle with a rack-and-pinion feed system and an adjustable depth stop.

· Function: Provides smooth, manual control over the drilling feed rate, allowing precise cutting depths and automated spring-back after drilling completion.

· Benefit: Protects the hole saw teeth from sudden impact damage and allows for rapid, repetitive boring operations.
