Heavy Duty Double Head Xy Cnc Spot Welder Sheet Metal Welding Machines
Product Introduction:
The welding machine is a pneumatic double head spot welding equipment specially developed for the automation welding of elevator door panels. The main body is a standard fixed spot welding machine, with additional X/Y axis moving fixtures and fixture exchange racks. The total size is 5250 × 3775 × 2067mm. Its outstanding features include: the dual electrode head completes two welding points at once, the upper electrode moves vertically up and down, and the workpiece can move left, right, forward and backward. Workflow: After manual placement and manual start-up, the workpiece is moved to the welding position, the cylinder is pressurized and pressed, the thyristor is turned on for welding, the electrode is released after power failure, the workpiece is moved to the next point position and the above process is repeated. After all welding points are completed, it is moved to the exchange rack. This machine has low energy consumption, is safe and reliable, and can stably weld 0.5-1.5mm thick plates, making it a reliable assistant for door panel production.
Features:
1. Modular component design: Welding arms, conductive seats, cylinders, etc. can be independently disassembled, and there is no need to disassemble the entire machine for electrode replacement or maintenance.
2. Electrode quick change structure: The upper/lower electrodes are fitted with taper or threaded quick release, and can be replaced by hand within 30 seconds.
3. Self lubricating guide bearing: The moving parts of the upper electrode are equipped with oil containing copper sleeves or linear bearings, which do not require daily refueling maintenance.
4. Open X/Y tooling: The mobile slide guide rail is equipped with a scraper plate, and cleaning welding slag and dust only requires compressed air blowing.
5. Fault self diagnosis system: The controller can detect thyristor short circuits/open circuits, and the quality of solenoid valve coils, allowing maintenance personnel to directly locate the faulty module.
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.
