Scale breaking roll with dust suction function for cold rolling pickling line

Abstract

The invention relates to the field of auxiliary cleaning equipment for metal pressure machining, in particular to a cold-rolling pickling unit scale-breaking roller with a dust-sucking function. The cold-rolling pickling unit scale-breaking roller with the dust-sucking function comprises a swinging arm (100), and is characterized in that the swinging arm (100) comprises a front-end bottom plate (1), an outer sealing plate (2), a lifting lug (3), a top cover plate (5), an inner sealing plate (6), a shaft sleeve air outlet (8), a shaft sleeve (9), a rotating shaft (10), supporting frames (11), an air guide pipe (12), a front-end air guide plate (13), a bottom cover plate (15) and a side cover plate (16); and the two sides of the swinging arm (100) are provided with the supporting frames (11)correspondingly, the rear ends of the supporting frames (11) are arranged on and fixed to the rotating shaft (10) in a sleeving mode, and an inner cavity of the shaft sleeve (9) communicates with aninner cavity of the shaft sleeve air outlet (8). According to the cold-rolling pickling unit scale-breaking roller with the dust-sucking function, the structure is simple, installation is convenient,dust sucking is direct and effective, and adaptability is high.

Description

Technical field [0001] The invention relates to the field of auxiliary cleaning equipment for metal pressure processing, in particular to a scale-breaking roller with dust suction function for cold-rolling pickling units. Background technique [0002] In the straightening section of the cold-rolling pickling line, scale-breaking rolls are often used to strengthen the removal of scale on the surface of the strip. When the strip passes through the scale-breaking roller, the bending deformation is the largest, and the surface is in different stress states, which will cause different forms of tearing and peeling of the iron oxide scale on the surface, and the formation of fine iron oxide powder is also the most. If these fine iron powders are not collected effectively, not only the surface quality of the strip steel will be affected, but also the health of the operators in the area will be unfavorable. [0003] Existing dust removal systems are generally arranged in the subsequent pro...

Problems solved by technology

If these fine iron powders are not collected effectively, it will not only affect the surface quality of the steel strip, but also be detrimental to the health of operators in this area

[0003] Existing dedusting systems are generally arranged in the subsequent process of descaling rolls, but rarely take targeted dedusting measures for the process of descaling rolls, which produces the most oxidized fine iron powder on the surface of the strip, which will bring a lot of dust to the subsequent process. to greater difficulty and pressure
