Steel Pipe Rolling Machine CNC Plate Bending Machine Iron Sheet Rolling Machine
4 roller steel pipe rolling machine is the best metal fabrication equipment that is best solution for large production as it can be equpped with NC or CNC. The four roll iron sheet rolling machine provides total pre-bending to reduce the flat end to a minimum, The cnc hydraulic double pinch plate bending machine can considerably increase the productivity compared to 3 roll machine. and application of the cone rolling device, make it possoble to bending conical shapes. come to us to get best proposals for your project.
The structure of the CNC roller bender is a four-roller type. The upper roller is the main drive, and the output gear of the reducer meshes with the upper gear to provide torque for the rolled plate; the lower roller moves vertically and passes through the hydraulic cylinder. Hydraulic oil is obtained by acting on the piston to clamp the plate, which is hydraulic transmission; there are side rollers on both sides of the lower roller and tilting along the guide rail of the frame, which is driven by the screw nut, worm gear and worm. The design of the overload protection system of the rolling machine is very accurate, it can maintain the equipment well and reduce the occurrence of equipment failures.
This Advanced Design Has The Following Benefits Such As:
(1) Plate is introduced horizontally (and not tilted as on the three roll double pinch)
(2) Plate is squared instantly against the back roll (reducing risk of a mis-matched end condition of the part)
(3) Requires space only on one side of the machine, where the plate is introduced to the machine
(4) Greatly reduced flat-end (due to better pre-bending) thanks to the clamping roll that can take the edge to the precise tangent points of the top and bottom rolls
(5) It is the fastest machine to roll a can, as it would require only one position for each side bending roll
(6) The entire cylinder can be finished in only one pass (within a suitable capacity), including pre-bending of the edges
* No need to pre-bend both ends before starting to roll the entire cylinder, as required with a 3 roll
* No need to remove, turn and re-insert the plate as on a 3 roll single pinch
(7) The four roll could be even 50-80% faster and more productive than any style three roll
(8) The most suitable for CNC operation, as the plate is under a better control, clamped between the top and bottom rolls, until the part is finished
The Four Roll Design Is Recommend For Clients Who:
1. Wish to operate through CNC, with less dependence on operator skills
2. Look for more steady quality of the rolled products.
3. Look for high productivity, and increased profits.
4. Require good accuracy and quality improvements.
5. Need handling equipment for larger plates, who are also concerned for production or safety reasons.
6. Are new to plate rolling, as it is the easiest plate roll to operate. 
1. Extremely robust structure machined with CNC control machines
2. Two hydraulic motors coupled to planetary gear units for the rotation of the two central rolls
3. Hardened rolls / Hardened and polished rolls
4. Separate control desk on wheels
5. Hydraulic opening of shoulder by control desk
6. Hydraulic inclination of lateral rolls for conical bending directly from control desk
7. Numerical control for automatic production
8. Movements of rolls on swing guides to reduce flat part
9. It can be used to roll tubes, tube segments, rounded boxes, ovals or other shapes.
10. Rolls rotation on high resistance selfaligning bearings
11. Rolls Cambering: know how variable cambering to avoid reel and barrel effect to increase bending performance and precision
(1) How long is the service life of your product?
It depend on the worker skills and experience and working hours every day, if do normal maintenence for the rolling machine under instruction, its life can upto 10 years. and we need to see the working plan every day, if working 12 hours even more, that will effect the service life.
(2) What are the specific categories of your products?
We have main 3 kinds of roll bending machine, Mechanical 3 roller, hydraulic 3 roller with prebending and hydraulic 4 roller with pre bending.
(3) What are the specifications and styles of existing products?
We have light and heavy types rolling machine, thickness from 6-150mm, width 1000-12000mm, and we can make special machine as per customer special request, for example, smaller rolling diameter, special application like oil pipe, wind tower, loader etc.
The temperature of the condensed water discharged from the steam drum of the evaporation tank is higher than the steam temperature of the steam drum of the next effect tank. If it is decompressed in a container, self-evaporation is generated, and the steam from the evaporation tank can be used as the heating of the lower-effect evaporation tank or the corresponding heater. This equipment is called a self-evaporation tank. There are two types of self-evaporating tanks used in sugar factories: column type and horizontal type.
These types of tanks are rolled by CNC roller bender. high precision and well performance
The structure of the column type self-evaporating tank is very simple, there are no moving parts, and there will be no mechanical failure. The operation is safe and reliable, no manual management is required, and it also functions as a steam condensate eliminator. Therefore, this self-evaporating tank has become a common device in standard thermal processes.
