3 Rolls Heavy Plate Bending Machine

Brief Introduction

Three-Roller Bending Machine can be classified into two types, namely mechanical bending machine and hydraulic bending machine according to the driving force. And the mechanical ones can be further classified into symmetrical and dissymmetrical machine. It can make the sheet metal rolled into round, arc or some conical parts.

Application:

Hydraulic Three-Roller Bending Machine can be widely applied in a wide range of fields, including petroleum, chemical industry, cement, boiler, shipbuilding, aviation, water conservancy, power transmission towers and so on.
Components and Advantages

1. Built-in Pressure Cylinder:



The pressure cylinder’s setting on the lathe bed can avoid the piston rod damage triggered by accumulating rolling scales as well as rod exposure during the bending process. Our Three-Roller Bending Machine realizes the non-rod chamber work for both top and bottom cylinders, and reduces the amount of bearing seals, while increasing the reliability.

2. Strengthened Cone Bending Package:


A small cone-shaped slowing device is set on the top and bottom of bearing block. Hence, it can meet the requirement of specific bending, like small diameter, large cone angle bending. The electrical system of it can also flexibly control the working rollers inclination so as to maintain the top roller balance.

3. Advanced Hydraulic Release Pressure System:


With special design of hydraulic as well as working pressure checking systems, Our Hydraulic Bending Machine for Heavy Plate can be unloaded under high pressure, thus avoiding the problem of bouncing and "water hammer”, which makes the work piece compact while piping.

4. Clean Human-Machine Interface:

The screen can display the working pressure of each hydraulic cylinder, motor working state, displacement of sensor, the power failure of each valve, each soft and hard limitation, overload alarm, and oil temperature alarm.
