Product details
1、 Overview
This machine belongs to the imported Japanese technology hydraulic three roll plate rolling machine, which is used to roll steel plates into cylindrical, conical, circular arc and other shapes.
W11S-30 × 2500 Universal Rolling Machine with Upper Roller Digital Display Diagram
This machine belongs to the hydraulic three roll plate rolling machine, which is used to roll plates into cylindrical, circular arc, and conical shapes at room temperature.
The upper roller can move vertically or horizontally.
Pre bending is achieved by horizontally moving the upper roller to an asymmetric position relative to the lower roller.
When rolling, the two lower rollers are driven by an electric motor and a reducer.
Due to the unchanged elevation of the lower roller, it is convenient for feeding and operation.
The tipping frame adopts hydraulic tipping.
The vertical displacement of the upper roller is driven by hydraulic transmission, while the horizontal movement is driven by mechanical transmission.
Adopting PLC programmable display control.
Provide a detailed electrical schematic diagram, strictly follow the electrical wiring diagram, and ensure that the numbers on both ends of each wire are clear and complete. The wire terminal block should be labeled with the same wire number as the wire, and corresponding markings should be made on the electrical wiring diagram and schematic diagram;
All electrical components used in the equipment are high-quality products from well-known enterprises. Electrical protection devices (such as current relays, air switches, etc.) must be strictly tested by the electrical manufacturer before installation to ensure reliable operation.
The hydraulic components used in the equipment are branded products. The equipment runs smoothly, controls flexibly, has no jamming, oil leakage, and abnormal noise.
Adding a cone device can roll cones within a certain range.
The equipment has high reliability and low failure rate.

Performance and Features:
1. High precision end pre bending
Free setting of straight edge length, direct pressure pre bending of the upper roller, capable of achieving high-precision end pre bending.2. NC control, high production efficiency
The process parameters of rolled products are normalized, making operation simple and significantly improving efficiency.3. The precision of the product exceeds the standard
The upper roller is in the shape of a drum, and the lower part of the lower roller is adjusted by a support roller, which can continuously bend and roll ideal products from thin plates to thick plates.4. Safety of homework
Two rollers are fixed, and the upper roller moves up and down, left and right. The workpiece does not move with the work roller, ensuring the safety of the operator.5. Integrated structure, simple foundation, easy to move
The equipment adopts an integral chassis, without the need for anchor bolts, with a simple foundation and easy mobility in the workplace.6. Different uses, corresponding control methods
According to the purpose, there are the following control methods:
TNC (Upper NC): Multiple varieties, used for small-scale production;
T&BNC (upper and lower NC): Used for mass production with few varieties.7. Rich curved shapes
It has a rolling O-shaped, U-shaped, multi-stage R, and auxiliary cone device, which can roll a certain range of cone tubes.
O-shaped bending: rear bending method
U-shaped bending: Forward bending method:
Multi segment R bending: combined method.
