Description

Technical Field

[0001] The invention relates to a cutting mechanism used when rolling a connected elevator guide rail. Background Art

[0002] Currently, elevator guide rails are mostly rolled individually, which is inefficient. If two guide rails are rolled at the same time, production efficiency can be improved, but there is currently no equipment suitable for online cutting of two conjoined guide rails.

[0003] In addition, due to the small cross-sectional size and asymmetrical shape of the rolled piece (elevator guide rail), the deformation of the rolled piece is large during the rolling process, and the straightening workload is large; while the two conjoined guide rails are connected to each other at the heads, the cross-sectional size of the rolled piece is large and the shape is symmetrical, so the deformation of the rolled piece is small during the rolling process, which can reduce the straightening workload.

[0004] The invention patent with publication number CN105290109A discloses a method for rolling a conjoined elevator guide rail, that is, by changing the hole shape of the roller assembly, a conjoined elevator guide rail can be rolled out, and then the two elevator guide rails can be separated by shearing.

[0010] A slitting roller is provided below the straightening roller. The slitting roller has a two-half structure, that is, the slitting roller consists of two slitting roller monomers, which are connected by a number of connecting bolts. A gap is left between the two slitting roller monomers, and the connecting bolts exposed from the gap are covered with a spacer sleeve. The gap between the two slitting rollers is located directly below the slitting blade. The slitting roller is installed on the slitting roller shaft, and the inner and outer support plates are provided with through holes at the positions corresponding to the slitting roller shafts.
