J21S Series Deep Throat Flywheel Press

The deep throat punching machine drives the flywheel by the motor with the crank linkage mechanism, the flywheel drives the large gear through the shaft and the pinion gear, the large gear drives the crankshaft through the clutch, and the crankshaft drives the connecting rod to make the slider work. The number of strokes per minute of the slider and the motion curve of the slider are fixed.

Deep throat punching machine is also called deep neck punching or deep sea mouth punching machine. It refers to the distance from the center of the die hole of the punch to the back wall plate. The throat depth is in 300mm, 500mm, 800mm and 1250mm, which should be customized according to actual production needs.

Deep throat punching is a kind of punching machine, generally used in sheet metal punching. For example, the blind window opened in the middle of the large electrical box or electrical cabinet, the cat’s eye opened in the middle of the security door.

Because the distance between the hole and the edge of the plate is usually more than 300mm or more, the throat depth of the ordinary punch is only about 180-230mm. After the plate is put into the punching machine, the wall plate is pressed against the sheet, which needs to be realized by deep throat punching.

Deep throat punching machines are widely used in aircraft, luxury bus and high-speed EMU silencer and heat sink punching, hole punch of the blind window on electric box and electrical cabinets, security door locks, cat eye, fresh cabinet heat emission.
