The gear feed machine is a pioneering apparatus, instrumental in the realm of high-speed, precision stamping industries. Its application ranges from motors to transformers, from welding machines to AC contactors, carving a niche for itself as a game-changer. In comparison to its peers, the roller feed machine and the clamp feed machine, this mechanical marvel stands out, thanks to its unique power utilization strategy. Its operating energy comes not from an internal power device, but from the output shaft of the punch. This innovative approach enables the gear feed machine to deliver high-precision, high-speed step feeding capabilities, optimally utilizing energy and providing cost-effective solutions.
Assembly and Mechanics of the Gear Feed Machine
The assembly of the gear feed machine revolves around a key component: an eccentric wheel, mounted onto the output shaft of the punch. This wheel connects to a transmission rod, further linked with two umbrella gear groups. The power transmission process involves another pair of transmission rods, driving the pressing cam and feed wheel, two crucial elements of the system.
The pressing cam plays a central role in actuating the rocker. This triggers the oscillation of a small swing arm. During this oscillation, the swing arm applies pressure to a push rod in the feed seat, placed strategically on the pivot of the feed wheel. This initiates the feed seat’s reciprocal movement, accurately pressing the feeding clamp on the pivot of the feed seat.
From Coiled Metal to Precise Stamping
The transformation journey of coiled sheet metal begins with the uncoiling machine, followed by a high-speed U-type or S-type leveling machine that ensures the metal’s uniformity. The prepared sheet metal is then seized by the feeding clamp in the feed seat, awaiting the rotation of the feeding wheel. A strategically positioned screw on the side of the wheel propels the clamped sheet metal in the feed seat.
The Dance of the Cam and the Swing Arm
Adjacent to the feed wheel of the gear feed machine, a cam shares the same axis. This cam induces motion in one end of a large swing arm, anchored at its midpoint. This results in the other end of the swing arm swinging, pushing a vertically moving sliding seat at the rear of the feed seat.
The sequence of movement between this cam and the feed cam is perfectly staggered, 180 degrees apart. This precise coordination allows the feed seat to return to its original position smoothly, once the sheet metal reaches its designated location and the large swing arm has clamped the sheet metal in place. Consequently, the pressing cam can easily press the feeding clamp for re-clamping, while the sliding seat descends, releasing the sheet metal for the feed seat to begin another feed cycle.
Two buffer springs, mounted on either side of the screw pivot between the push feed seat and the pushing screw, absorb any interference arising from the overlap of the two cam journeys. This subtle synchronization enables precise alternation of the two journeys, completing the clamping work, and thus ensures the speed and accuracy of the gear feed machine.
The gear feed machine, through its innovative power sourcing and meticulous mechanical coordination, redefines the benchmarks of high-speed, high-precision stamping. Its ingenious design and operational efficiency pave the way for a new era in industries such as motors, transformers, welding machines, and AC contactors. This gear feed machine truly stands as a testament to human ingenuity and the power of engineering.
