Almost every workshop needs a good metal sheet rolling machine (steel plate bending machine). PRA and PR4 sheet metal bending machine from Borisbang Industrial Technology (BIT) is a perfect choice. The PRS, PRA, or PR4 small sheet metal roller offers a simple and rugged design, offering the medium to small fabricator years of quality service.
The difference between metal sheet rolling and metal plate rolling: If the thickness of the metal is ¼” (6mm) or more, then it is considered a plate. Plate thickness is typically measured in inches. If the thickness is less than ¼” (6mm), it is considered a metal sheet. Roll bending the metal sheet(thickness <6mm ¼”) or metal plate, (thickness >= 6mm ¼”), is pressed into great accuracy cylinders and cones, to make bulk storage containers, ductwork, piers for oil rigs, panels for the hulls of ships, etc. Read More: Plate Rolling
PR4 Sheet Metal Rolling Machine
The PR4 Sheet Metal Rolling Machine/Equipment can roll with a thickness of 4-12mm sheet metal. Used for cylinder pressure vessel manufacturing industries, PR4 Sheet Metal Rolling Machine has functions of roll-bending round, pre-bending, and correcting the circle, with a coarse leveling function.
Four Features of Specification
Roller: The upper roller of the sheet metal rolling machine is the main transmission, leading the lower roller and the side roller to move by friction between the steel plate/sheet metal and the upper roller, meanwhile, the upper roller provides torque for rolling rollers. The upper roller is the active roller by hydraulic transmission, lower roller, and the accessories, both sides turn plane and supporting roller lifting are driven by hydraulic pressure. The lower roller uses vertical lifting, and the side roller use tilt lifting, so the synchronization precision error is less than 0.15mm.
Pre-bending: To make pre-bending, the lower roller rises and clamp the sheet metal, the side roller inclined upward, sheet metal end pre-bending is done. According to the arrangement of the side roller to adjust the position of the two sides, the four-roll sheet metal rolling machine can do symmetric or non-symmetric bending so that the sheet metal rolling machine can be a rolled ideal very small arc straight edge into the theory of surplus. Compared with the symmetrical 3-roll sheet metal bending machine, four roller rolling machines do not need to use a pre-bending sheet metal press anymore.
Control System: The four-roller rolling machines’ control system adopted Japan OMRON intelligent high-speed PLC or CNC industrial control systems, the system can control the lower roller and the other roller accessories. The lower roller and the two-side roller’s displacement sensor use an encoder, so the action design of the sensor is reasonable, which can guarantee service life.
Bearings and Hydraulic Systems: All bearings used in the four-roller rolling machine are required to adopt the most advanced technology, from the most well-known manufacturers of leading products. Hydraulic cylinder with accurate manufacturing, good sealing effect, so the cylinder reduces the pressure relief and leakage of sealing device, in addition, all sealing accessories are imported from world famous brand products.
PRS Sheet Metal Rolling Machine is a three-roller symmetrical steel plate/sheet metal rolling machine(Read More:Bending Machine Wikipedia). It is mainly used to bend plates with a thickness of less than 3/8″(10mm) (σS≤245Mpa) into cylindrical tubes of various diameters during the cold working process. It is widely used in boilers, Chemical, mining, construction, shipbuilding, and other machinery industries.
