Precision welding \u00b7 MCB thermal trip assembly<\/div>\n

MCB Bi-metal Support Frame Automatic Welding Machine<\/h1>\n

MCB Bi-metal Support Frame automatic welding machine: The bi-metal strip, the indispensable core of the MCB thermal trip mechanism, is welded onto its support frame or carrier with sub-millimeter alignment accuracy and flawless joint strength, therefore enhancing the overload tripping performance of the miniature circuit breakers.<\/p>\n

This includes a servo driven workpiece positioner, a programmable welding power supply (capacitive discharge or inverter DC), machine part feeder, accurate pick\u2011and\u2011place of bimetal strips, alignment against a preadjusted distance, application of specified welding energy, and finally verification of product quality by either pull\u2011test or monitoring welding resistance. The whole cycle is PLC\u2011controlled, and parameters can be entered for each different type and size of bimetal and support frame. Outputs are in the range 1200 to 2000 welds per hour and defects are usually reduced to nil.<\/p>\n

Lead time: 30 to 45 days. Precise positioning is ensured within \u00b10.05mm. Thermal trip time satisfies requirements of IEC 60898\u20111.<\/p>\n<\/p><\/div>\n

What is an MCB Bi-metal Support Frame Automatic Welding Machine?<\/h2>\n

An MCB Bi-metal Support Frame automatic welding machine. This machine joins the thermal strip to the metal support frame (or carrier); this is a very important subassembly of the thermal trip unit in miniature circuit breakers. The bimetal strip deforms when heated by the overload current, and this position, together with the integrity of the weld, determines the trip accuracy (IEC 60898\u20111). This is a precision resistance welding (or capacitive discharge welding) machine that creates a consistent, low\u2011resistance joint without damaging the bimetal. Vision\u2011guided or mechanical part alignment, automatic part feeding, and in\u2011process quality checks (monitoring pull force or weld energy, for example) are featured, and the system is designed for 24\/7 running in high\u2011volume MCB manufacturing plants.<\/p>\n

Key Advantages of Automated Bi\u2011metal Welding<\/h2>\n
\n
\n

Consistent thermal trip performance<\/h4>\n

The weld position and energy directly control bimetal deflection. Automation eliminates variation from manual welding, ensuring every MCB trips within its IEC time\u2011current curve.\n <\/p><\/div>\n

\n

Zero\u2011defect quality target<\/h4>\n

In\u2011process energy monitoring and optional pull\u2011test verification reject defective welds immediately, reducing field failures caused by loose bimetal attachments.\n <\/p><\/div>\n

\n

Schneller Wechsel<\/h4>\n

Recipe\u2011based parameters and quick\u2011change welding electrodes allow switching between different bimetal\/frame sizes in under 15 minutes.\n <\/p><\/div>\n

\n

Higher throughput<\/h4>\n

Manual welding achieves 200\u2011300 assemblies per hour; this machine produces 1,400\u20112,400 per hour \u2013 a 600\u2011800% increase.\n <\/p><\/div>\n<\/p><\/div>\n

Kundenerfolgsgeschichte<\/h3>\n

An MCB manufacturer in Vietnam was encountering a 3% bimetal weld failure using a manual resistance welding system resulting in thermal trip rejects at final calibration. By utilising our automatic welding machine the defect rate fell to 0.1%. The automating energy monitoring also took into account electrode wear and warned operators of impending drift before actual quality standards were reached. The increase in production varied from 800 to 2,000 welded assemblies per shift and the equipment was eventually paid for in 8 months.<\/p>\n
