Product Introduction:
The dual-head capacitor discharge projection welding special machine is a semi-automatic welding powerhouse purpose-built for carbon steel circular buckle clamps (clamps/hoop clamps). The equipment innovatively adopts left and right dual vibratory bowl feeders to automatically feed small buckle parts; the operator only needs to place the ring, and the dual independent welding heads press down stepwise according to the program, using millisecond-level capacitor discharge to instantly complete projection welding at both ends. It not only thoroughly solves the problems of welding deformation and heavy spatter in ring-shaped thin-wall parts, but also produces attractive and strong weld spots. With the support of a pneumatic-hydraulic booster cylinder and a fully enclosed safety guard, plus one-touch touchscreen operation, it enables your hardware workshop to easily achieve high-efficiency, high-consistency mass production.
Features:
1.Custom-built for clamps/buckle clamps: A non-standard automated dual-head projection welding special machine with strong application focus.
2.Left and right dual vibratory bowl automatic feeding: Small buckle parts are fed automatically, eliminating manual picking and placement.
3.Capacitor discharge welding with millisecond-level discharge: Minimal spatter, small heat-affected zone, and no deformation of thin-walled rings.
4.Dual-head stepwise precise pressing: Independent cylinder control ensures uniform force on weld spots, with no cold welds or missed welds.
5.Single clamping, both ends formed: Workers only need to load the ring and remove the finished part; production capacity doubles, and ordinary workers can operate it.
6.HMI touch screen: Safe and reliable, with pressure/time/energy visible and adjustable at the touch of a button.
