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 rod 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 a cold-rolled steel coil uncoiler reel, which includes a hollow mandrel, a push-pull rod arranged in the hollow mandrel, a pyramid sleeve, a door key, a fan-shaped plate and a block; the pyramid sleeve and the fan-shaped plate are internal and external The wedges are matched and connected by sliders; the fan-shaped plates can expand and contract in the radial direction, and the angle of the wedges is in the range of 14° to 15°. main features. The purpose of increasing the amount of expansion and contraction of the reel is realized under the condition of small diameter of the reel and small reciprocating stroke of the push-pull rod. It has the characteristics of reasonable and compact structure, practical and convenient operation, large radial expansion and contraction of the reel, and a wide range of inner diameter changes for incoming steel coils.

Description

Technical field [0001] The invention relates to a cold-rolled steel coil decoiler reel, which belongs to metallurgical machinery technology. Background technique [0002] Among the numerous steel rolling process equipment, the first equipment is the uncoiler that opens the billet steel coil. The decoiler drum is a component of the decoiler with a cantilever 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 carrying capacity of the reel and the amount of radial expansion and contraction determine the applicable scope, service life and the stability of the rolling process equipment of the uncoiler. [0003] At present, the radial expansion and contraction of the existing uncoiler drum is in the range of 30-7mm, and the angle of the pyramid sleeve is in the range of 7°-12°. Due to the small expansion and contraction range of the reel, the requirements for the cha...
