Steel coil tensioning device of full-automatic uncoiler

Abstract

The invention provides a steel coil tensioning device of a full-automatic uncoiler, belongs to the technical field of uncoilers and overcomes the defects of high price, huge volume, difficult popularization and application and short service life of a conventional large heavy-duty uncoiler. The steel coil tensioning device of the full-automatic uncoiler comprises a hollow rotary shaft of which one end part serves as a construction section and the other end serves as a cantilever section, and a plurality of tensioning plates distributed at the periphery of the cantilever section of the rotary shaft; the construction section of the rotary shaft is connected to a base; a connection rod is arranged between each tensioning plate and the rotary shaft; one end of the connection rod is hinged to the corresponding tension plate, while the other end is hinged to the rotary shaft; and the tensioning plate is connected with a spreading / shrinking mechanism capable of driving all tensioning plates to spread or shrink at the same time. The tensioning device has the advantages of low manufacturing cost, adaptability to various steel coils with different specifications and relatively light weight, less abrasion, good tensioning effect and long maintenance period.

Description

technical field [0001] The invention belongs to the technical field of fully automatic uncoilers, and relates to a steel coil tensioning device, in particular to a steel coil tensioning device applied to a fully automatic uncoiler. Background technique [0002] In the plate processing industry, large-scale rolling equipment is usually used to continuously press and form metal plates. In order to facilitate production, improve efficiency and reduce labor intensity, the raw material plates used are pre-wound into cylindrical steel coils and stored in special on the charging rack so that it is kept in a reasonably controlled state. An uncoiler is a device that unrolls a cylindrical steel coil continuously or intermittently. [0003] At present, there are many forms of uncoilers. From the function, there are mainly mechanical passive uncoilers, semi-automatic uncoilers, automatic uncoilers and other uncoilers. No matter what kind of uncoiler, there is a steel coil on it.
