Automatic expanding and shrinking waste edge coiling machine drum

Abstract

The invention discloses an automatic expanding and shrinking waste edge coiling machine drum, which comprises a main shaft and a barrel, wherein the main shaft is connected with a transmission shaft of a transmission device, and the barrel is sleeved outside the main shaft and used for coiling the waste edge; the barrel consists of at least two barrel petals; each barrel petal is connected with the main shaft through a telescopic mechanism; and the telescopic mechanism is used for driving the barrel petals to stretch along the barrel in the radial direction. The drum realizes automatic expansion and shrinkage of the barrel and automatic falling of waste coils, so the drum can reduce the taper of the barrel, increase the effective coiling space, prolong the uncoiling period, effectively improve the production rhythm and meanwhile avoid the scratch of the barrel; and the processing precision requirement for the surface of the barrel is greatly reduced, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the coiling technology of waste edges cut by disc shears after pickling of cold-rolled strip steel, in particular to a waste edge coiler reel. Background technique [0002] In the cold rolling production line, the steel plate after pickling needs to be cut by disc shears to meet the requirements of the width of the finished strip, and the waste edges cut by the disc shears need to be treated accordingly. At present, there are two ways to deal with the waste edge: one is to directly chop the waste edge, and then return the chopped waste edge to the furnace; the other is to roll the waste edge into regular steel coils, which can be like finished steel Sold as a roll. It is not difficult to see that the waste edge coiling has a very high economic value from the application of the waste edge treated by the two methods. Therefore, the waste edge coiler is widely used. [0003] The reel of the waste edge coiler is a conical structu...

AI Technical Summary

Problems solved by technology

At present, the reel of the existing waste edge coiler is integrally welded, and the expansion and contraction of the cylinder cannot be realized. In order to realize automatic blanking by self-weight, the taper of the cylinder is designed to be large, and in order to reduce friction, the surface of the cylinder The manufacturing and processing precision requirements are very high, and the manufacturing cost is relatively high; moreover, when the waste edge with a large thickness is coiled, the additional tension is relatively large, so that after the waste coiling is completed, it often happens that the material cannot be blanked, and the operator needs to use a pry The rod unloads the waste roll from the barrel, which greatly affects the production rhythm; at the same time, after a long time of production, the barrel and clamping head will be severely worn, and automatic blanking cannot be realized, and a new roll has to be replaced
