Plate Bending Machine

Brief Introduction
Plate Bending Machine, also named plate rolling machine, is a sheet shaping machine that rolls the metal sheets through continuous points. It is simply constructed with the upper roller moving vertically or horizontally. It can produce different shapes of plate, such as O sections, U sections and R sections, etc. and also provide pre-bending, bending, as well as correcting work pieces. Plate Rolling Machine is widely used in petroleum, chemical industry, cement, boiler, shipbuilding, aviation, water conservancy, power transmission towers and so on.

1. Three-roller plate bending machine is mainly adopted in the production of circular hulls of the ship. Based on the clients’ requirements, the three-roller Plate Bending Machine can be designed symmetrically or dissymmetrically. It can realize the non-rod chamber work of the cylinders and reduce the amount of the bearing seals. Our machine has been widely adopted in shipping, boiler, aviation, hydropower, chemical industry, mental construction and mechanical manufacturing industry.
2. Four-roller plate bending machine can bend the edges of the plate, thus when rolling thin plates, Plate Bending Machine can avoid sheets’ skidding and also make the coarse plates become smooth.

The Whole Structure of Hydraulic Plate Rolling Machine:

Our Plate Bending Machine embodies both upper and lower rolls driven by hydraulic motor, electrical motor and planetary gear box. It can well function by the joint efforts of the following mechanism: horizontal movement mechanism, supporting mechanism, downturn system, chassis and balance mechanism.

The Features of Hydraulic Plate Rolling Machine:

(1). High precision pre-bending, flexible setup of the plate’s width.
(2). Upper roller can not only makes horizontal and vertical movement without moving the plate, but also can collaborate with carrier roller to realize continual bending of plate of any thickness.
(3). Unitary structure with a hardy pan, making it convenient to move the whole machine as there is no need to anchor bolt.
(4). Different controlling ways are available for different operations, like top numerical control and below numerical control.
(5). By adopting exclusive technology, Plate Bending Machine can eliminates the scars on the surface of the shell or roll as well as avoids the need for grinding the lamination (bull nosing) on the minor diameter edge in most cases.

CNC Control System:

1. Typical of TC computerized numerical control.
2. HMI (human machine interface) for the intelligent operation.
3. Self-compensating, highly efficient, safe and convenient.
4. Many models for choice.

Major Parts Involved When Manufacturing Plate Bending Machine:

1. Working rollers: cast steel ingot (chemical composition analysis): check performance-forging roughcast — forging annealing-UT flaw — roughing (mechanical tests)-heat treatment (hardening and tempering) — UT flaw — semi finishing — finishing — MT.

2. Large forgings: cylinder body, gear, gear shaft forging roughcast — surface inspection – roughing — UT flaw — UT flaw detector heat treatment — finishing semi—finishing — MT.

3. Welding structure: racks, chassis, wheel box

4. Plate into the factory (chemical composition analysis, mechanical properties test) — pretreatment — for sheet metal cutting-welding-seam UT or RT flaw — annealing treatment — roughing-finishing— vibration destressing—hot blasting —finishing
