Integrated quick roll changing device for high-speed bar production line

Abstract

The invention provides an integrated quick roll changing device for a high-speed bar production line, and aims to solve the problem that in the prior art, the amount of labor for changing movements islarge. The integrated quick roll changing device comprises a bottom rail, a sliding car, a transport car, a second driving piece and an automatic unhooking mechanism, wherein the bottom rail is parallelly arranged in a rolling direction; the sliding car can be driven by a first driving piece and does reciprocating motion on the bottom rail; the transport car is used for loading new and old movements; the second driving piece of a fixed structure is used for pushing or pulling the transport car; and the automatic unhooking mechanism is used for connecting the second driving piece with the transport car. When the old movements are replaced with the new movements, collaborative operation of multiple workstations on the production line can be achieved; through the design of the automatic unhooking mechanism, automatic fastening and locking and automatic unhooking after the movements are in place can be achieved in the middle transfer process without the help of other unhooking or lockingdriving pieces.

Description

technical field [0001] The invention relates to the field of iron and steel manufacturing equipment, in particular to an integrated quick roll changing device for a high-speed bar production line. Background technique [0002] Due to the high passing speed of the pre-finishing rolling unit of the high-speed bar production line, the wear of the rolling groove is relatively faster, the service life is relatively shorter, and the replacement is more frequent. How to complete the roll changing operation faster and better has become a key node for the high-speed bar production line to reduce invalid downtime and increase production capacity. [0003] The existing method is: the movement is assembled offline by an assembly team, and lifted to the vicinity of the rolling mill. When changing rolls, first cut off the connection of energy medium pipelines, loosen the locking mechanism, use the roll changing trolley to pull out the movement to be replaced, then lift the old movement a...
