Problems solved by technology

Undoubtedly, the above-mentioned patents have shortcomings such as unreasonable structure and inconvenient practical operation, and can only be applied to steel coils with an inner hole diameter > φ1900mm, especially because of the long length of the mandrel and the large reciprocating stroke of the push-pull drive mechanism, and its scope of application is limited. limit
To sum up, the above-mentioned existing technologies do not meet the current industry standard process requirements of uncoiler reel specification φ625max / φ610 / φ510min×1500mm

Abstract

The invention discloses an uncoiler drum of cold-rolled coil, comprising hollow core shaft, push-pull rod, pyramid sleeve, bond trough bore, sector plate and fixture block. The pyramid sleeve is cooperated with the sector plate in internal and external wedges and they are connected by sliding block. The wedge angle is in 14degree-15degree. Concave grooves, which can be used to avoid interference with each other in movement, are set on the pyramid sleeve and the sector plate respectively. The purpose of enlarging expansion and shrinkage quantity of drum is realized under conditions that the drum diameter is small and the to-and-fro journey of push-pull rod is small. It is provided with reasonable and compact structure, convenient operation, large expansion and shrinkage quantity of drum along the radial direction and wide change range of internal diameter of incoming material steel coil so on.

Description

technical field [0001] The invention relates to a cold-rolled steel coil uncoiler reel, which belongs to metallurgical machinery technology. Background technique [0002] Among the many pieces of equipment in the steel rolling process, the first piece of equipment is the uncoiler that opens the billet coil. The uncoiler reel is a component of the uncoiler with a cantilevered shaft-shaped radial expansion and contraction structure, which ensures that the incoming steel coils of different specifications are matched with it and work normally. The bearing capacity of the reel and its radial expansion and contraction determine the application range, service life and stability of the rolling process equipment of the uncoiler. [0003] At present, the radial expansion and contraction of the uncoiler reel is in the range of 30-70mm, and the wedge angle of the pyramid sleeve is in the range of 7°-12°. Due to the small range of expansion and contraction of the reel, the requirements...
