AUTOMATIC WIRE-NAIL MACHINE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: machine has a body, a drive, a wire metering feed mechanism, a wire clamping mechanism, a wire sharpening and cutting mechanism with a positioning mechanism, an upset slider with a punch fastened to it, the punch has a positioning mechanism. A multiple-link reduction gear is rigidly connected to a drive and is located on the central axis of the device. A profile templet roller is mounted in the body of the wire metering feed mechanism. The upset slider is made in the form of a body with an inner cavity on which outer surface gear racks are fastened symmetrically to the axis of machining. The upset slider positioning mechanism is made in the form of a load-carrying impact spring positioned in the body of the upset slider, an end force regulator of the load-carrying impact spring and two gear rims mounted on output shafts of the multiple-link reduction gear for engagement with the gear racks of the upset slider body. The wire sharpening and cutting mechanism is made in the form of two hollow bodies positioned symmetrically to the wire feed axis, the gear rack is fastened on the outer surface of each body. Its positioning mechanism is made in the form of two load-carrying compression springs each of which is mounted in the cavity of the corresponding body of the wire sharpening and cutting mechanism, end force regulators of the corresponding compression spring, and two gear rims mounted on output shafts of the multiple-link reduction gear. EFFECT: improved structure. 3 dwg
