The invention discloses a strip material roll shearing roll extruding mechanism. The strip material roll shearing roll extruding mechanism comprises an uncoiler, a
welding machine, a storing material tensioning gear, a roll shearing roll extruding unit, a length detection camera
system, a measuring
pile, an outlet storing material pendulous device, and a recoiling
machine which are arranged in sequence; a flat guide roller is arranged between the
welding machine and a inlet storing material device, and a flat guide roller is also arranged between the roll shearing roll extruding unit and the length detection camera
system; the roll shearing roll extruding unit is composed of a tension pad, a vertical guide roll, and four
hobbing press racks which are arranged in sequence; a unit is arranged between each pair of
hobbing press racks; two guiding devices are arranged in front of the two
hobbing press racks close to the vertical guide roll respectively; hobbing
cutting tools are arranged on the hobbing press racks close to the vertical guide roll; and roll extruding
cutting tools are arranged on the rest hobbing press racks. Raw materials of automobile sealing strip skeletons are subjected to uncoiling using the uncoiler firstly. The strip material roll shearing roll extruding mechanism is capable of ensuring continuous
processing of automobile sealing strip skeletons in installation of new
strip steel coiling blocks; the tension pad is capable of protecting the surfaces of the automobile sealing strip skeletons from scratches, adjusting automobile sealing strip skeleton tension, and ensuring the type of coil is qualified.
