Metal Cabinets Double Spot Welding Machine For Steel
Product Introduction:
The welding device is an efficient and intelligent automatic spot welding machine for door panels. It is based on a fixed spot welding machine, adds dual electrode synchronous welding function, and is equipped with X/Y-axis moving fixtures and fixture exchange racks. Its working principle is clear: after manually placing the flat workpiece into the fixture and starting it with both hands, the equipment automatically moves the workpiece to the welding position; Firstly, execute the pressurization program, and the electromagnetic valve drives the cylinder to vertically press the upper electrode against the workpiece; Continuing with the welding program, the thyristor conducts to control the transformer to generate welding current; After welding is completed, the thyristor is turned off, the electrode is released, the workpiece is displaced, and the above steps are repeated until all points are welded, and finally moved to the exchange rack. The overall size of the machine is 5250 × 3775 × 2067mm, with a welding thickness of 0.5~1.5mm. The pneumatic system is stable and reliable, and the overall efficiency is energy-saving and easy to maintain.
Features:
1. Optimization of whole machine footprint: Although it includes X/Y fixtures and exchange racks, the welding machine body only accounts for about one-third of the total size of 5250 × 3775 × 2067mm, which is suitable for local layout in the workshop.
2. Vertical movement of the upper electrode: Without a rocker arm or extension arm rotating mechanism, the equipment has the lowest top height and can be installed in factories with limited height requirements.
3. Side hanging design of tooling exchange rack: closely attached to the welding machine body, without occupying additional front and rear channels, making it convenient for a straight line layout.
4. The controller is integrated into the body: there is no independent electrical cabinet, reducing cable dragging on the ground, and the overall appearance is simple.
5. Integrated valve island for pneumatic components: The cylinder, solenoid valve, and pressure regulating valve are centrally installed on the back of the machine body, with short pipelines and few leakage points.
Detailed Images:
Double Electrode Head (up/down): A pair of copper alloy electrodes that directly contact the workpiece (welding 2 points at a time), apply current under pressure, concentrate heat on the contact surface of the plate to form a weld core, and complete spot welding.
X/Y Fixture Moving Mechanism: Driven by servo or stepper motor, the screw/synchronous belt accurately moves the workpiece in the horizontal plane, aligning the welding points of the door panel with the electrodes in sequence, achieving multi-point automatic welding.
Intermediate Frequency Control Box: Inverts AC power to DC power, achieving millisecond level high-precision welding, effectively reducing spatter, saving 30% energy, and significantly reducing transformer weight. It is particularly suitable for stable welding of materials such as aluminum and galvanized sheets.
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.
