Roofing Sheet Shearing Machine

Roofing sheet shearing machine is specialized cutting equipment tailor-made for color steel roof panel,wall sheet and glazed tile production lines,working as a key matched device after uncoiler and roll former.It cuts continuous formed color coated steel,galvanized steel,aluminum roofing sheets into customized fixed lengths,directly determining finished roof panel dimensional accuracy,incision quality and overall production efficiency of building material factories.Focused on thin roofing sheet processing,its applicable cutting thickness ranges from 0.25 mm to 3.0 mm,with common working widths of 1000 mm,1250 mm and 1300 mm to fit mainstream raw coil widths for roof material manufacturing.

Classified by driving forms,roofing sheet shearing equipment mainly includes mechanical flywheel type and hydraulic guillotine type.Mechanical shearing machines feature compact structure,fast cutting frequency and affordable cost,widely adopted by small and medium roofing sheet workshops with intermittent production.Hydraulic roofing sheet shearing machines run smoothly with stable shearing pressure,less sheet deformation during cutting,which is the mainstream option for full-automatic continuous roll forming production lines.Most complete roofing production lines select linkage-type shearing machines that connect electrically with upstream roll forming host to achieve fixed-length automatic cutting without manual control.

The machine consists of heavy welded frame,high-hardness customized cutting blades,NC backgauge positioning component,driving system and electrical control cabinet.The whole machine body adopts thick steel plate integral welding followed by stress relief treatment to prevent frame deformation under long-term cyclic cutting load.Cutting blades use high alloy tool steel with overall quenching processing,designed according to the thin characteristic of roofing sheets,ensuring neat cutting edge free of burr,collapse edge or sheet curling,avoiding defective finished roof panels caused by rough incision.Equipped with digital backstop positioning system,production staff sets target cutting length on PLC control panel;servo backgauge automatically adjusts position for precise sizing,abandoning traditional manual measuring and marking operation.Standard safety infrared grating is installed near the cutting zone to halt blade movement instantly once unexpected intrusion happens,securing on-site operators’personal safety.

Its working flow closely cooperates with the roofing sheet forming line.After raw color steel coil is unwound by decoiler and shaped into continuous roofing profile via roll forming machine,the formed sheet moves forward to the shearing machine worktable synchronously.When the sheet reaches preset length,the forming machine sends synchronous signal to the shearing unit;the cutter instantly drops down to finish one-time straight cutting,then the finished single roofing sheet falls onto discharge rack automatically for collection.In unmanned automatic production workshops,matching conveying roller tables are equipped to transport cut finished products to stacking area continuously,greatly reducing manual material handling workload.Users can adjust cutting speed and shearing pressure on control panel according to different material hardness such as PPGI,galvalume and pure aluminum sheets.

Outstanding targeted advantages make this shearing machine irreplaceable in roofing material processing.First,professional blade design fits thin roof sheet processing perfectly,controlling cutting tolerance within±0.1 mm and lowering product rejection rate effectively.Second,host linkage automatic cutting cuts over 35%of labor cost compared with separate offline cutting equipment and remarkably boosts daily line output.Third,compact floor space fits limited workshop layout of small roof tile factories,convenient for installation and daily routine maintenance.

At present,roofing sheet shearing machines are in great export demand for prefab house,industrial factory roofing and warehouse wall panel manufacturers in Southeast Asia,Middle East,Africa and Latin America.Along with continuous upgrade of intelligent roof panel production,PLC-controlled fully automatic linkage shearing machines with counting and batch cutting functions become mainstream purchasing choice for new production lines,constantly promoting the development of global color steel roofing processing industry.
