Automatic equal-diameter hole punching machine for liquid-cooled pipes

High precision, stable hole drilling, excellent heat dissipation, smooth liquid cooling fluid flow, and corrosion-resistant 316L piping conforming to drawing requirements.

This fully automatic equal-diameter hole-drawing machine for liquid-cooled pipes is designed for high-efficiency, high-precision hole drawing of stainless steel/copper pipes in liquid-cooling systems (new energy, data centers, energy storage, etc.). Its core advantages are as follows:

Processing Accuracy and Quality (Core Requirements for Liquid Cooling)

• Equal-diameter hole drawing + flanging in one step: The outer diameter remains essentially unchanged, with extremely high precision in hole position and flanging height (servo ±0.02mm, flanging error ≤0.1mm)

• Burr-free orifice, smooth inner wall: Near-mirror finish, significantly reducing liquid resistance, refrigerant residue, and improving heat exchange efficiency

• Uniform wall thickness, no deformation: Suitable for thin-walled/thick-walled liquid-cooled pipes, ensuring pressure resistance and sealing reliability

• 36° rotational precise positioning: Multiple rows of holes, multiple angles, and multiple spacings are completed in one clamping operation, resulting in extremely high consistency.

Prduction Efficiency and Automation

• Fully automatic process: Loading → Feeding → Clamping → Hole drawing → Flanging → Discharge, completely unattended.

• High Speed: Stainless steel 10-12s/hole, copper tube 5-6s/hole, suitable for mass production of liquid cooling pipes

• Quick Changeover: CNC/PLC stores multiple programs, one-click switching on touchscreen, adaptable to different pipe diameters/hole spacings

• One Person, Multiple Machines: Significantly reduces manpower and reliance on skilled technicians

Specific Advantages for the Liquid Cooling Industry

• Compatible with Liquid Cooling Pipes: Stainless steel 304/316, copper, carbon steel, wall thickness ≤3.5mm, pipe diameter φ12.7–φ220mm

• Zero Leakage Guarantee: High flanging strength and good sealing performance, meeting the high-pressure/long-term operation requirements of liquid cooling systems

• Dedicated Liquid Cooling System: Protects the blade, protects the tube, and controls temperature, extending mold life and stabilizing processing quality

• Non-standard Customization Available: Adaptable to complex structures such as water distributors, manifolds, and liquid cooling plate pipes

Equipment Stability and Cost

• High Rigidity Machine Body + Servo Drive: Stable accuracy and low failure rate during long-term operation

• Long mold life: Dedicated hole-drawing mold, suitable for continuous batch production

• Reduced post-processing: No need for secondary deburring, grinding, or shaping, resulting in lower overall costs

Process flow: Laser pre-drilling of the bottom hole, followed by hole drawing, shaping, and flattening into a single machine with an accuracy of ±0.1mm. A powerful tool for butt pipe welding, reducing the labor intensity of workers, offering high efficiency and high precision.
