W12-25X2000 PLC Controlled CNC Four Rollers Rolling Machine with Pre-Bending Function

Product Description

W12-25X2000 PLC Controlled CNC Four Rollers Rolling Machine with Pre-Bending Function 

Main uses and application of equipment
W12 series four-roller plate rolling machine has pre-bending function at the end of the plate. The metal sheet can be finished pre-bending and rolling at the end without turning head. The remaining right angle of the cylinder is small.It has a mobile independent operation desk, To improve work efficiency, ensure the quality of the workpiece, and the process is simple, easy to operate, is the ideal machine for rolling round, arc-shaped workpieces in oil, chemical, boiler, shipbuilding, hydropower, metal sheet structures and other industries.

1. Upper roller part: The upper roller part is composed of upper roller, bearing, hydraulic motor and planetary reducer. The upper roll section provides torque to the rolled sheet. The working roll is the main part of the equipment, using high-quality steel 42CrMo material, after rough processing, quenched and tempered HB220~260, medium frequency quenched after finish machining HRC46-52

2.Side roller part: The side roller part is composed of side roller, bearing, arm, cylinder, etc. The side roller section provides a bending deformation force for the rolled sheet. When feeding the rolled plate, one side roller can be used as a counter device.

3.The lower roller part: The lower roller part is composed of the lower roller, the bearing, the lower roller bearing seat, the lower roller oil cylinder and the like. When the lower roller part is pre-benting, it can clamp sheet metal to prepare pre-bent as straight flange
 

Top support system: (optional)
The top bracket is the center upper bracket, which is installed behind the fuselage.
It consists of a movable stand. The support can be translated up and down according to the size of the cylinder, and supported from the inside of the cylinder during the winding stage. The medium and above center upper bracket has a tie rod fixed to the ground. The user must embed the anchoring device in the foundation.
The center upper bracket is either hydraulically driven or mechanically driven and is controlled by an electrical system.

 

Left and right support system: (optional)
Hydraulic support on both sides, also known as side bracket: It is used to support both sides of the large-diameter cylinder to prevent the rolling accuracy of the steel plate due to the drooping weight during the rolling process. The hydraulic support on both sides has multiple rows of rollers, and each side can be divided into two sections to better support the cylinder. The hydraulic support can be used as a raceway at normal time, and the hydraulic support on the feed side is provided with an axial hydraulic push rod.

Rolling Process:

 

Work roller balance control
Diagonal slide rail: Using the most advanced and sophisticated EPS electronic balancing system (as shown below), XTW Machine Tool Company's W12 series machine tools have an EPS electronic balancing system, through 2 sets of hydraulic cylinders for synchronous movement, OMRON PLC central controller to ensure that the work rolls under any coil load are perfectly parallel. The trim error of EPS is ±0.1mm.
