With the fast developing of metal part processing technology, it’s more and more popular and widely usage of coil feed laser cutting line.
1. Raw material is coils not blanks, coil was payoff by decoiler and feed to laser cutting machine after flat by precision straightener/leveler machine, reducing steps of cut coil to blanks firstly and then take blanks to laser one by one, saving material cost, manpower & material resources, increasing producing efficiency etc.
2. It has great advantages for multi-sizes and small order quantity products of coil feed laser cutting line than blanking line by punch machine with stamping dies. As each size product may need one set mold, it will cost too much for muti-sizes and small order quantity products, for laser machine, it just need to program in the computer and start to produce immediately.
3. It can make several products in one row for laser machine, saving material cost. On the contrary, for blanking line by punch machine with stamping dies, it has to zigzag feeding for punch’s feeder or it has to slit to be required coil to produce one in a row.
4. Comparing to produce by punch machine with stamping dies, product surface flatness is better of laser cutting, improving the utilization efficiency of raw materials.
5. Higher degree of automation, more suitable for long-term continuous processing of workpieces.
Comprising of the blanking line
1) MT-1800 model 15T hydraulic decoiler 1set
2) 15T loading car 1set
3) SHL-1800A model straightener with feeder 1set
4) Electric cabinet 1set
5) RMT-1800 model scrap recoiler 1set
1. MT-1800 model 15T hydraulic decoiler
Function: It was used to loading coil and payoff strips automatically.
3. 15T coil car (refer to above image)
Function: It was used to load coils and automatically lift the coil to the mandrel of the unciler machine. And then the mandrel can expand and clamp the coil.
a) Loading capacity 15T (can be customized)
b) Motor power hydraulic type
c) Coil fix method 4pcs fixing bar
d) Coil width:250-1800mm (Min. Width coil should be fix by fixing bar)
4. SHL-1800A model Straightener with feeder
4.1 Machine image (just for reference)
4.2 Machine main feature
Electric adjust straightening roller gap. Just need to set data in HMI’s touch screen (refer to the following image). Moreover, it has the function of memory and call it back of the producing data: such as different products different part code, straightener gap set data. (Refer to following image)
Support bridge. It was used to guide strip head and assist strip head conveniently inserting straightener’s entrance and then go through straightener part. It also set support bridge at straightener’s exist part so as to guide straightener head inserting feeder’s entrance.
3 Electric cabinet with operation panel
It was used to control the total zigzag coil feeding line. All main components come from worldwide famous brands with CE CERTIFICATION, good quality and safety, such as full sets of Schneider low voltage components, Japan Mitsubishi PLC, Japan YASKAWA servo motor etc.
Machine main electric & electronic components
4 Scrap recoiler
It was used to roll scrap strips into coils, it equips with inverter, so machine’s running speed is adjustable of 1-15m/min
