330-800mm Core Height | Automatic Tube-Laying Radiator Core Assembling Machine |

This equipment is specifically designed for automotive radiator core assembly, handling the automatic arrangement and fixing of tubes, fins, side plates, and header plates. Featuring an automatic tube-laying mechanism driven by a motion controller and servo system, it enables continuous feeding and precise positioning of radiator tubes. Typical applications include passenger car and commercial vehicle radiator core assembly lines, particularly suited for single-row tube cores and multi-variety, medium-to-small batch mixed-flow production.

2. Industry Challenges & Root Cause Analysis

Low tube-laying efficiency:Manual or semi-automatic methods rely on workers placing tubes one by one – slow and error-prone. Root cause: lack of automated tube feeding and sequencing mechanisms.

High changeover cost:Different core sizes require extensive tooling replacement and complicated adjustments. Root cause: tube magazine and support structures lack width-adjustable designs, requiring disassembly and reassembly of multiple components.

Insufficient end-face leveling accuracy:Uneven tube and fin ends compromise subsequent header plate pressing quality. Root cause: no dedicated leveling mechanism – relying on manual tapping results in poor consistency.

Header plate positioning deviation:Misalignment between header plates and tube ends causes tube deformation or plate damage. Root cause: lack of precise coordinated control between header positioning and tube-laying platform.

3. Solution

3.1 Automatic Tube-Laying Mechanism:Tube magazine width adjustable via modular inserts; tube length adjusted by gear motor. Tube push mechanism uses servo-driven dual sprockets with pusher blocks on chains for continuous feeding – fast and stable. Magazine traversing uses servo motors with dual timing belts for smooth movement.

3.2 Core Support Worktable:Core height adjustment via servo control; table surface uses precision aluminum profiles – accommodates various core heights.

3.3 Fin/Tube Leveling Mechanism:Integrated design levels tube and fin ends to provide flat end faces for subsequent header plate pressing – high changeover versatility.

3.4 Core Clamping Mechanism:Linear guide rails with servo-driven clamping force. Clamping base positioned beneath the support table – accommodates different edge-distance specifications.

3.5 Header Plate Positioning & Pressing:Combination tooling with header locating modules and left/right positioning cylinders – accurately positions header plates and presses them onto the arranged tubes.

3.6 Operation & Control System:Motion controller and touchscreen with manual/auto dual modes; product parameters storable and recallable – intuitive HMI programming.
