Product Introduction:
Non standard customized dual head energy storage resistance projection welding machine, specially designed for efficient welding of carbon steel circular buckle clamps (clamps/clamps). The resistance welding machine integrates left and right dual vibration discs for automatic feeding, dual independent welding heads, gas-liquid booster cylinder, and energy storage welding control box. During operation, manual placement of large circular pieces is only required, and the left and right vibration discs automatically send the buckle small pieces to the welding station. The resistance welder presses down and discharges them step by step from left to right according to the preset program, and uses millisecond level energy storage convex welding technology to instantly complete the fusion. The fully enclosed safety protection and touch screen control system ensure safe operation and adjustable parameters, greatly reducing manual intensity and perfectly solving the pain points of easy deformation and large splashing in the welding of thin-walled circular pieces. It is an ideal choice for the hardware fastener, auto parts, and home appliance industries to achieve high-quality mass production.
Features:
1. Extremely low heat affected zone: Energy storage discharge is only completed in an instant, and the workpiece does not generate large-scale heat conduction, perfectly maintaining the original metallic properties and appearance color of carbon steel.
2. Say goodbye to secondary polishing: The convex welding process, combined with precise discharge energy, results in almost no spatter during the welding process. The fusion joint between the buckle and the ring is smooth and flat, eliminating the need for manual polishing and polishing costs in the future.
3. High consistency at both ends: The PLC program strictly controls the timing and discharge energy of the left and right welding heads, ensuring that the welding strength and appearance of the buckle at both ends of the same clamp are completely consistent.
4. Convex point centralized welding: Using pre stamped convex points of buckle small parts, current is concentrated through the convex points to instantly collapse and weld, forming a strong metallurgical bond with high tensile strength.
5. Independent pressure regulation: The left and right cylinders are equipped with independent pressure regulating valves, which can adjust the welding pressure on the left and right sides according to different material thicknesses or protrusion sizes, making the process adjustment extremely flexible.
Welding Test:


Welding Workpiece: Specifically engineered for welding Tabbed Steel Clamp Rings, and also broadly accommodates various ring-shaped hardware components such as Pipe Hoops, Exhaust Clamps, Hose Clamps, Pipe Clamps, Tab Clamps, Metal Fastening Rings, and U-clamps. Whether processing ring-shaped metal parts with custom Stamping Tabs made of carbon steel, galvanized steel, or stainless steel, the equipment utilizes a dual-head, step-by-step capacitor discharge projection welding process. This perfectly solves the common pain points of thin-walled ring welding—such as thermal deformation and excessive spatter—making it highly suitable for mass production across industries including hardware fasteners, automotive parts, home appliance assemblies, and pipeline engineering.

Dual independent welding joints and upper and lower electrodes: The left and right dual head program controls step-by-step downward pressure, ensuring even force distribution and preventing displacement; The high conductivity copper alloy electrode ensures precise, consistent, and secure solder joints at both ends.

Pneumatic-hydraulic intensifier cylinder: It outputs strong and stable thrust several times higher than conventional air pressure, ensuring instant compression without bouncing, and eliminating virtual welding and leakage from the source.

Left and right double vibration discs and feeding mechanism: Automatic directional sorting and precise delivery of small fasteners, achieving fully automatic feeding without manual grasping, significantly reducing labor intensity and improving cycle time.

Energy storage welding control box: Built in large capacity capacitor with millisecond level pulse discharge, heat concentration, minimal splashing, perfectly solving the pain points of thermal deformation and annealing of thin-walled ring components.
