W12-61500 Four-Roll Plate Rolling Machine Shipped
Today, a W12-61500 hydraulic four-roll plate rolling machine completed full-machine commissioning and inspection, was successfully loaded and shipped, and will soon arrive at the customer's workshop. As a mainstay machine for thin plate rolling and forming, the W12 series four-roll plate rolling machine is widely recognized in the sheet metal, tank, pipeline, and steel structure industries for its core advantage of completing pre-bending and rolling in a single loading. The W12-61500 model delivered this time is a popular choice for thin plate forming among small and medium-sized processing enterprises.
Model Parameters Explained
Many customers new to plate rolling machines cannot understand the meaning of the model. Breaking down W12-61500: W12 stands for
four-roll hydraulic plate rolling machine series
; 6 stands for
maximum rollable plate thickness of 6mm for ordinary carbon steel
; 1500 stands for
effective plate rolling width of 1500mm
. This model is suitable for carbon steel thin plates up to 6mm. When processing stainless steel plates, it is recommended to appropriately reduce the thickness to ensure forming quality. The machine uses the upper roll as the main drive, and the lower roll and both side rolls are hydraulically raised and lowered. The rolls are quenched and tempered, wear-resistant and not easily deformed. The overall structure is solid and stable.
Working Principle & Core Advantages
The biggest highlight of the four-roll plate rolling machine compared with traditional three-roll machines:
Single clamping, no need for plate flipping or turning, directly completes pre-bending of both ends of the plate + cylindrical shell rolling and forming
.Processing flow: the plate is fed between the upper and lower rolls; the lower roll rises hydraulically to clamp the steel plate and prevent slipping during rolling; the two side rolls are raised and lowered independently by hydraulic pressure to pre-bend both ends of the plate, greatly shortening the remaining straight edges; the rotation of the rolls drives the plate to reciprocate and feed, gradually adjusting the side roll height to control the bending radius, and continuously rolling out arcs and full-circle workpieces; after forming, the workpiece can be unloaded directly, eliminating the secondary pre-bending and manual plate-flipping processes.
Compared with three-roll plate rolling machines: three-roll equipment leaves long straight edges at both ends of the plate, and after rolling the cylindrical shell, a separate press is still needed to pre-bend both ends, resulting in more processes and higher labor costs; the W12 four-roll model provides good pre-bending results, with extremely small remaining straight edges, higher cylindrical shell roundness, and a neat finished product appearance, making it suitable for mass production of cylindrical shells and curved workpieces with high forming precision requirements. At the same time, the side rolls are independently adjustable, and with the aid of supporting tooling, conical shell parts can also be rolled, making it a multi-purpose machine.
Applicable Industries & Workpieces
W12-61500 is a small-to-medium four-roll plate bending machine, specializing in thin sheet processing. It is widely used in sheet metal fabrication plants, environmental protection equipment, ventilation ducts, pressure vessel accessories, steel structures, water tanks and tank bodies, construction machinery parts, and other fields. It can process various cylinders, semicircular arc parts, and conical cylinders. Products such as dust removal equipment shells, stainless steel water tanks, duct elbows, and equipment guards can all be roll-formed with this machine.
Equipment Delivery and After-Sales Service
Before the equipment leaves the factory, we have completed no-load and load test runs of the whole machine, inspected the hydraulic system, roller runout, and control system to ensure all indicators meet standards; the whole machine is spray-painted for protection, and secured for loading to avoid bumps during transportation. Thank you for trusting us and choosing our W12 four-roll plate bending machine. After the equipment arrives at the customer's site, technical personnel can be arranged for installation guidance, operation training, and explanation of equipment operating procedures, hydraulic system maintenance, and roller maintenance key points. We remind customers to replace hydraulic oil on time during daily use, clean the roller surface, avoid welding slag and hard objects scratching the roller surface, and extend the service life of the equipment. We wish the customer smooth production startup, a continuous stream of orders, and win-win cooperation!
