Enclosures Spot Welding Machines for Sheet Metal
Product Introduction:
A double headed automatic spot welding machine designed specifically for mass production of elevator door panels. Based on the standard fixed spot welding machine, it creatively adds double electrode heads (welding two points at once), X and Y axis moving fixtures, and fixture exchange racks, with a total size of 5250 × 3775 × 2067mm. After manual loading and unloading, the switch is activated with both hands, and the workpiece is automatically moved to the welding position; The upper electrode moves vertically under pneumatic pressure to press the workpiece tightly; The thyristor precisely controls the conduction angle, enabling the welding transformer to be energized and generate current; After welding, the thyristor is turned off, the electrode is released, and the workpiece is moved to the next welding point cycle. After completion, it is sent to the exchange rack. This machine can weld 0.5-1.5mm thick plates, with a simple and compact structure, novel and beautiful appearance, and efficient energy-saving characteristics due to the use of thyristor control, making it safe and reliable to use.
Features:
1. PLC+HMI fully digital control: Welding timing, movement trajectory, and pressure regulation are all controlled by programs, and parameters can be uploaded to the MES system.

Double Electrode Head (up/down): One compression, dual point simultaneous welding - This pair of upper and lower copper alloy electrode heads can be called the "dual guns" of spot welding. Under stable pressure, they instantly flow through, allowing heat to be precisely locked in the contact surface of the plate. In the blink of an eye, fusion nucleation is formed, and two welding points can be completed in one go. Not only does the welding speed double, but the welding points are also firm and beautiful, greatly improving the welding capacity of door panels and making your production line run faster and more stable!

X/Y Fixture Moving Mechanism: Say goodbye to the troubles of manual moving and inaccurate alignment - The X/Y fixture moving mechanism uses servo/stepper motors combined with screw rods or synchronous belts to quickly and accurately "move" the workpiece in a horizontal plane. Each welding point is automatically sent to the electrode, and multi-point welding is completed in one go, greatly improving the efficiency and yield of door plate welding, saving labor and reducing strength. It is a powerful assistant for automated production lines!

Intermediate Frequency Control Box: Say goodbye to the splashing and high energy consumption of traditional power frequency welding - the intermediate frequency control box uses intermediate frequency DC inverter technology to achieve millisecond level rapid response, making each weld precise and controllable. The splashing reduction is immediate, saving 30% electricity. The lightweight design of the transformer allows the equipment to move and be installed easily, whether it is aluminum or galvanized plate, it can easily weld the perfect effect, helping you reduce costs and increase efficiency in one step!

Human Computer Interaction Interface: Touch screen or button panel, used to set welding parameters, call programs, display status and alarms, and achieve intuitive operation dialogue between people and devices.
