1 Roll plates from 6 mm, up to 80-100 mm thick
2 Machines are suitable machines for production of cylinders, ovals and square shaped objects
3 Fully welded and stress relieved before machining to have sufficient strength
4 The four rolls bending machine utilizes 2 driven rolls to ensure the rolling torque power transfer
5 Steel rolls with optimal crown
6 Easily Complete Pre-Bending, Elliptic, Polycentric & Conical Bent Shapes
7 Hardened rolls as standard
8 The remaining flat end is as short as one time the plate thickness
1 Secured rolling traction throughout the process
2 Accurate and easy to operate
3 High strength steel rolls are very crack-resistant
4 The plate is kept squared without slipping during the pre-bending and bending cycle
5 The material grip is assured between top roll and lower roll always
Prebending of edges without turning the sheet over
2.Description of finished products
Ferrules in full circle or varying radiuses can be done easily
3.Description of coil capability
4-ROLL plate bending machines are ideal for plates thicknesses 6- 150 mm and widths 500 – 6000
(1) Cooling and heating systems pipes
The bending rolls designed are widely applied in the production of heating and ventilation equipment. The machines are ideal to roll thin metal plates and mass produce pipes for fireplaces, stoves, household boilers or air handling and ventilation systems. an extensive range of 4-roll and 2-roll bending rolls suited to meet effectively the needs of manufacturers in the industry.
(2) Food Industry bending machines
Specialized in the production of plate bending machines for the food industry with four rolls and numerical control indispensable for the production of stainless steel food containers, which offers strength and longevity
1、Why need rolls camber?
Roll camber is required to counter act roll deflection that occurs as bending forces are applied, so as to ensure a perfect closing of the longitudinal seam, it is a vitally important factor. If the camber is calculated incorrectly, the result will be.
(1) a barrel shaped cylinder ie not closing perfectly along the longitudinal seam, gap in the middle.
(2) an hour glass shaped cylinder, the longitudinal seam touching in the middle, but not at the ends.
