Power Transformer Radiator Automatic Production Line

Loading

Lift high-quality cold-rolled coil plate raw materials to the loading station of the automatic uncoiling equipment, ensuring the raw materials are placed stably and accurately positioned to prepare for subsequent production processes.

Automatic Uncoiling
The automatic uncoiling equipment monitors the tension and uncoiling speed of the coil material in real time through sensors, automatically adjusting the uncoiling status according to production needs. This ensures the coil material is smoothly and continuously transported to subsequent processing procedures, avoiding issues such as coil slack or breakage.

Roll Forming

High-precision roll forming dies are used to continuously roll and process the coil material. Through gradual extrusion and forming by multiple sets of rolls, the coil material is processed into radiator shapes that meet design requirements. During roll forming, the dimensions and shape accuracy of radiators can be precisely controlled by adjusting the spacing and angle of the rolls.

Automatic Plating

An automated plating device is used to accurately position and combine the roll-formed single radiator plates according to the set plate spacing and center distance, providing a good foundation for subsequent welding processes. During the plating process, sensors and mechanical grippers work together to ensure accurate plating positioning.

Multi-Point Welding 1 (Odd Points)

A multi-point welding machine is used to perform spot welding on odd-numbered points of the plated radiators. Multiple welding heads work simultaneously to quickly complete spot welding at odd positions, initially fixing the connection parts of the radiators and improving welding efficiency.

Multi-Point Welding 2 (Even Points)

Subsequently, spot welding on even-numbered points is carried out, cooperating with odd-point spot welding to further strengthen the connection between radiator plates and make the radiator structure more stable.

Double-Side Seam Welding

A double-side seam welding machine is used to perform continuous seam welding on the two side edges of the radiators, forming firm weld seams to ensure the sealing and overall strength of the radiators. During seam welding, parameters such as welding current, welding speed, and electrode pressure are controlled to ensure uniform weld quality.

End Seam Welding 1 (Head)

End seam welding is performed on the head of the radiator to strengthen the connection strength at the head, preventing end cracking and other issues during use and ensuring the integrity and reliability of the radiator.

End Seam Welding 2 (Tail)

Similar to head seam welding, end seam welding is performed on the tail of the radiator to ensure both ends of the radiator have good connection strength and sealing performance.

Double-Side Rolling Cut

Rolling cutting equipment is used to precisely roll and cut the two side edges of the radiator, removing excess material to ensure the radiator width meets design requirements. This also makes the edges smooth and flat, improving the product's appearance quality.

End Cutting

End cutting equipment is used to cut the head and tail of the radiator, ensuring the end length meets design standards and the overall dimensional accuracy of the radiator.

Flattening

Flattening equipment is used to flatten the radiator, eliminating deformation and warping generated during production to make the radiator surface flat and smooth, improving product flatness and quality stability.

Unloading and Sorting

The processed radiators are automatically unloaded from the production line and sorted, facilitating subsequent assembly and packaging processes.

Assembly

According to product design requirements, the sorted radiators are assembled with other components to complete the entire production process of power transformer radiators.
