The machine is four roller plate bending machine, upper roller as initiative roller, down roller and side rollers as driven rollers; upper roller is fixed, down roller does up and down movement; Upper roller is mechanical initiative, while down roller and side rollers are driven by friction from plate and rollers.
Down roller and side rollers are driven by hydraulic oil tank to do lifting movement.
Upper roller’s ventro-bearing overturn and reset are also driven by hydraulic oil tank.
Rollers’ bearing and oil tank are installed on left and right side of machine frame.
Left and right machine framework are the main parts of whole machine, which is totally steel welded, installed on the welded base, and all operations are finished on console.
It’s easy to operate,rich shape bending
Double pre-bending without return
Aligning the material is convenient and accurate, avoid wrong side phenomenon
Once forming, the productivity is higher 50%-80% than three rolls plate bending machine
The top and bottom roller clamp the plate during rolling without slipping
The minimum bending diameter of cylinder can get to 1.5times the diameter of top roller,the almost almost no flat edge.
Rolls (42CrMo with quenching treatment)
Compared with three roller plate bending machine, this four roller plate bending machine can finish end pre-bending without other device or mold, and the left straight edge is little; compared to asymmetric three roller plate bending machine, this four roller plate bending machine can complete bending without turning around the plate.
In this way, user can improve work efficiency, guarantee the workpiece quality, besides, four roller plate bending machine has simple craftwork, convenient operation, and reduce the work strength to a large extent.
