Shelf Pillar Roll Forming Line

Shelf pillar roll forming line adopts industrial control PLC and man-machine operation interface to realize production automation; by inputting product length, hole distance, quantity and other parameters, it can complete punching, forming, cutting and other processes at one time during production; continuous production without stopping to ensure products Stable quality and accurate size.


The shelf column plays a supporting role in the storage shelf. As the height of the shelf increases and the number of layers increases, the column is heavily loaded, and most of them use cold-formed punching thin-walled steel, which has certain processing stress remaining and actual stress. The situation is also more complicated, so the design and selection of the column has become the key to the entire shelf system, which is directly related to the safety of the structure and the economy of use.

Shelf pillar roll forming line adopts industrial control PLC and man-machine operation interface to realize production automation; by inputting product length, hole distance, quantity and other parameters, it can complete punching, forming, cutting and other processes at one time during production; continuous production without stopping to ensure products Stable quality and accurate size.

Shelf pillar roll forming line is mainly composed of uncoiler, power leveler, CN servo feeding mechanism + punching mechanism, roll forming machine, electronic control system, hydraulic system, mechanical tracking and shearing mechanism and other components.
