Problems solved by technology

However, when the thickness specification of the strip steel is less than 0.5 mm or the material thickness of the strip steel head and tail is different, manual welding on site is difficult, time-consuming, and the welding quality is difficult to guarantee. Any bumps will cause scratches to the roll surface on the production line

Abstract

The invention relates to a strip steel sewing machine tool, comprising: a frame, an upper stamping mechanism, a lower stamping mechanism and a flattening mechanism. The strip stitching machine tool provided by the invention realizes the automatic fast stitching of strips on a continuous cold-rolling production line, improves operating efficiency and safety, reduces manual welding and stitching labor intensity, production preparation time, and improves production capacity. The present invention completely adopts the cold stamping method to carry out strip steel stitching, realizes the punching and flanging and flattening through the servo motor and the electric cylinder, does not generate light, heat, noise and smoke pollution during the processing, and does not need to use pressurized fluid, On-site applicability is stronger. During stitching, the upper stamping head, lower punching head, and flattening head of different specifications and sizes can be selected and switched according to the minimum bending radius of the strip steel on the production line roll equipment to ensure that the strip steel will not remain on the roll surface during riveting. under scratches.

Description

technical field [0001] The invention relates to a strip steel sewing machine tool, which belongs to the technical field of cold stamping processing. Background technique [0002] In the continuous production of cold rolling, when the strip on the production line is broken or artificially cut off due to equipment maintenance, it is necessary to reconnect the head and tail of the cut-off part of the strip before the production line starts production. The connection is mainly completed by on-site manual welding. However, when the thickness specification of the strip steel is less than 0.5 mm or the material thickness of the strip steel head and tail is different, manual welding on site is difficult, time-consuming, and the welding quality is difficult to guarantee. Any bumps will cause scratches to the roller surface on the production line. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the shortcomings of the ...
