Variable-diameter coiling machine

Abstract

The invention discloses a variable-diameter coiling machine, and belongs to the technical field of metallurgical machinery. The variable-diameter coiling machine comprises a rack, and is characterizedin that two ends of a 6-inch reel are fixed to one lateral side of the rack through bearing seats, the right end of the 6-inch reel extends out of the bearing seat and is connected with a motor through a coupler, and the bearing seats at the two ends of the 6-inch reel are respectively hinged to one air cylinder through a hinge lug; the two ends of a 3-inch reel are fixed to the other lateral side of the rack through bearing seats, the bearing seats at the two ends of the 3-inch reel are respectively connected with one air cylinder through a hinge lug, the bearing seats are connected with a linear sliding block, the linear sliding block is arranged on a linear guide rail and slides on the linear guide rail, and the linear guide rail is fixedly mounted on the rack. The variable-diameter coiling machine realizes the coiling of ultra-thin stainless steel belts with different inner diameters, improves the product tension precision and edge rolling uniformity precision, reduces the labor intensity of an operator, ensures the operation safety, and provides a high-level and high-precision stainless steel product for a user.

Description

technical field [0001] The invention belongs to the field of metallurgical machinery technology, and is specifically used for the production of ultra-thin stainless steel strips in the precision strip steel industry. Background technique [0002] In the stainless steel industry, the coiling inner diameter of the usual coiler is mostly 408mm, 508mm, etc., while customers in Japan, Europe and the United States require an inner diameter of 3 inches and 6 inches, and the edge coiling effect must reach ±0.2mm. The configuration of the existing unit The gap with the above-mentioned requirements is too large, and the coiling of steel coils with an inner diameter of 508mm can only be realized, and the size of the reel is severely limited, and diameter change cannot be realized. At the same time, the coiling tension of ultra-thin stainless steel is required to be 0.1~1.0N / mm 2 Between, while the existing equipment unit coiling tension is 2.5N / mm 2 Above, the high-precision coiling ...

[0002] In the stainless steel industry, the coiling inner diameter of the usual coiler is mostly 408mm, 508mm, etc., while customers in Japan, Europe and the United States require an inner diameter of 3 inches and 6 inches, and the edge coiling effect must reach ±0.2mm. The configuration of the existing unit The gap with the above requirements is too large, only coils with an inner diameter of 508mm can be coiled, the size of the coils is severely limited, and the diameter cannot be changed

At the same time, the coiling tension of ultra-thin stainless steel is required to be 0.1~1.0N / mm 2 Between, while the existing equipment unit coiling tension is 2.5N / mm 2 Above, the high-precision coiling of ultra-thin stainless steel cannot be realized, and the market requirements cannot be met.
