4 Roll Plate Bending Machine Tube Roller Machine SS Sheet Rolling Machine
We produces and sells various types of plate bending machines as per products application, material and rolling diameter. The range includes three models suitable for bending thin and thick plates: mechanical type three-roll bending roll with cheap price and hydraulic three-roll initial pinch bending roll with pre-bending function, and high speed and very high productivity four roll bending machines.
Now many factories use CNC-supported operation for thier production. CNC on four roll-plate bending machines specifically designed for bending round cylinders for applications like wind tower production line and also complex shapes for applications.
1. Bending of oval, elliptic or rounded box shapes is possible.
2. Pre-bending of sheet edges.
3. Numerical control for automatic mass production.
4. Conic bending device, conic bending positioning from control panel.
5. Hydraulic powered cover for easy material extracting.
6. Precise, faster and easier to operate.
7. Work piece only needs to be aligned once at the start of the bending process.
8. Simple cone bending.
9. Simple calibrating of apple- or pear-shaped welded tubes.
10. Can be controlled by CNC numerical control.
The warranty period of the equipment is 1 year, and the supplier shall be responsible for solving any quality problems in the equipment within 1 year.
During the warranty period, the buyer has the ability to resolve the fault by himself. In the event of a major fault, the supplier will give a clear answer within 24 hours after receiving the notice from Party A.
During the equipment warranty period, the supplier shall provide timely and free maintenance services for all types of equipment failures, and any non-human-caused parts damage shall be replaced free of charge in a timely manner. The warranty period of the replaced parts shall be recalculated from the replacement date.
(1) Metal Fabrication and Machining Workshops
Metal fabrication shops perform bending activities of various materials, from normal steel, to stainless and special high hardness steels.
(2) Plants for production of storage silos
Large-sized tanks and silos are not normally subject to major internal pressures and are therefore made by bending metal plates of small and medium thickness.
we offers tank manufacturers a range of 4-roll plate bending rolls for plates with thickness up to 20-30 mm able to meet any production requirement. Ideal for the production of large silos, typical applications being the food industry or storage of liquids.
(3) Tubes & Pipes
The pipes to convey fuel are usually mass produced. Production of such items therefore requires productivity, repeatability and automation.
(1) Why we use two hydraulic motors for 4 roller bending machines?
1. The upper and lower rollers can clamp the steel plate to prevent it from slipping when bending.
2. It is convenient for bending conical parts, elliptical parts and special-shaped products.
3. When using the CNC function, the rolling effect is better.
(2) Why adopt swing guide technology for bending plates?
What influences the flat-end of a rolled can? The flat-end (prebending) depends almost solely by the load that can be generated on the lower clamping roll.
The length of the flat-end does NOT depend by the side bending roll distance from the clamping spot, or large or narrow geometry of the side bending rolls, compared to the centre of the machine (the axis of the two clamping rolls).
The more load that can be applied on the bottom clamping roll, no matter how far the side bending roll would raise to bend the plate, the shorter the flat-end (best pre-bending).
