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

Embodiment

[0021]The strip stitching machine tool of this embodiment, such asfigure 1 withFigure 6 , Including: frame 1, upper punching mechanism 4, lower punching mechanism 3 and flattening mechanism 5.

[0022]Such asfigure 2 , Frame 1 adopts a G-frame structure welded by square steel and steel plate, with upper frame 1-3, middle frame 1-2 and lower frame 1-1. The length of frame 1 is greater than the maximum width of the strip to be processed 500mm, the upper and lower frames are 500mm away from the middle frame respectively; among them, the middle frame 1-2 is welded with 10mm steel plate as the bottom plate 1-4, and the two sides of the bottom plate 1-4 are also equipped with pallets 1-5 and pallets 1-5 It is made of electrical wood and is installed on the middle frame 1-2 by bolts, and the supporting plate 1-5 is flush with the bottom plate 1-4.

[0023]The upper frame 1-3 is equipped with an upper stamping guide rail 4-1 and a flattening guide rail 5-1; the flattening guide rail 5-1 and the u...

Abstract

The invention relates to a strip steel sewing machine tool which comprises a rack, an upper stamping mechanism, a lower stamping mechanism and a flattening mechanism. According to the strip steel sewing machine tool, automatic and rapid sewing of strip steel on a cold rolling continuous production line is achieved, the operation efficiency and safety are improved, the labor intensity of manual welding and sewing is relieved, the production preparation time is shortened, and the productivity is improved. Strip steel sewing is conducted in a cold machining stamping mode completely, punching flanging and flattening are achieved through a servo motor and an electric cylinder, light, heat, noise and smoke dust pollution are not generated in the machining process, fluid under pressure is not needed, and the field applicability is higher. In the sewing process, an upper punching head, a lower punching head and a flattening head of different specifications and sizes can be selected and switched according to the minimum bending radius of the sewn strip steel on roller equipment of a production line, and it is guaranteed that the strip steel does not leave a scratch on the roller surface while riveting is conducted.

Description

Technical field[0001]The invention relates to a strip steel sewing machine tool, belonging 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 is manually cut due to equipment maintenance, the head and tail of the cut strip must be reconnected before the production line starts. The connection is mainly completed by on-site manual welding. However, when the thickness of the strip is less than 0.5mm or the thickness of the head and tail of the strip is different, the manual welding on site is difficult, takes a long time, and the welding quality is difficult to guarantee. It is easy to cause recurrence of strip breakage after the production line is running, and any welding seam The bumps will cause scratches on the roller surface on the production line.Summary of the invention[0003]The technical problem to be solved by the present invention is to overcome the short...
