STRIP ASSEMBLING AND WELDING MACHINE Russian patent published in 2013 - IPC B23K37/04 

FIELD: process engineering.

SUBSTANCE: invention may be used at tube welding mills for production of high-quality 20-60 mm-dia tubes from stainless steel. Shears comprise fixed blades secured to bed and moving blades arranged on sides of housing displacing in bed vertical guides. Machine bed is composed of two halves with vertical slot there between to accommodate housing with shears. Housing drive is composed of two-slider drive mechanism. Said housing doubles as one of said sliders and is articulated with another slider furnished with horizontal displacement drive. Welding device copper shoe is equipped with horizontal displacement drive. Welding head is provided with rolls and cutter arranged there between to reinforce weld seam. Strip end reduction mechanisms are arranged to displace in machine bed horizontal guides with the help of slider. Said slider houses wedge mechanisms for strip end clamping and blades to cut odd strip parts with deficient weld seam.

EFFECT: expanded processing performances, decreased dimensions, easier servicing.
