Sheet Metal Cone Roller

Sheet Metal Cone Roller is a speical machine for bending sheet metal cone.The equipment is a cantilever tapered roller three-roller plate bending machine.

This equipment is a conical three-roller plate rolling machine. The three rollers are all conical rollers. The two lower rollers are in fixed positions. The upper roller is lifted and lowered hydraulically. The three rollers are all main driving rollers. Specially designed for rolling cone-shaped workpieces, it adopts centralized control on the operating console. It is mainly used to bend metal plates of a certain thickness into a tapered shape at room temperature. Its working principle is rotary bending deformation.

Cone Roller is used to bend metal plates of a certain thickne of sheet metal plate to a certain taper at room temperature.

Its working principle is rotational bending deformation.It is widely used in manufacturing industries such as petroleum, chemical industry, cement, shipbuilding, boiler, aviation, water conservancy, power transmission and transformation towers, etc.

The cone roller is consists of some parts.

1.Hydraulic system 

An independent hydraulic pump station is used, which is composed of oil pump motor, hydraulic valve group, pipeline auxiliary parts, etc. An oil pump motor drives the high-pressure gear pump to output pressure oil through an internal toothed elastic coupling. To ensure that the oil is clean, an oil filter is installed at the oil port of the oil pump. The pressure oil from the oil pump first enters the pressure regulating system. Set the pressure, then pass through the channel block and lead to the oil cylinder through the three-position four-way directional valve.

The hydraulic pump station system is manufactured in strict accordance with national and industry standards and is reasonably arranged. Fully consider high efficiency, energy saving, waste reduction, and heat source reduction. The system is independent, and professional sealants are used at appropriate connection points to prevent leakage and facilitate repair and maintenance.

Among them, the hydraulic pumps and hydraulic valves are all selected from famous brand series, and the oil cylinders are customized supporting products. The maximum working pressure of the system is 20Mpa. The pipeline layout is simple, with less leakage and easy maintenance and debugging.

The lifting and lowering of the upper roller is controlled by hydraulic valves (electromagnetic reversing valve, throttle valve, hydraulic control check valve).

The up roller up and down is controlled by two oil cylinders.

The cylinders control the top rolle front and back parts seperatelly.It can move up and down individually or simultaneously.

2.Host machine

1) Frame: It is made of integrally welded steel and steel plates and stress-relieved processing, with good strength and rigidity. It is easy to install and use, especially suitable for production requirements with strong mobility. It has low requirements on foundation and is convenient for relocation. The upper part of the frame is equipped with an upper roller pressing down oil cylinder, and the piston rod of the oil cylinder is connected with the upper roller bearing seat. The upper roller rises and falls together with the oil cylinder. The structure of the top-mounted oil cylinder is based on many years of practice. It absorbs the advantages of several Japanese, German, and domestic models and combines them with process requirements. Both cylinders of the upper roller work with rodless chambers to maintain the consistency of the system, that is, consistent working pressure, consistent compatibility, and a large effective area of the cylinder. There is only one dynamic seal, and the lifting speed is suitable for the rolling process requirements, which makes it easy to control the synchronization of the two cylinders, facilitates maintenance, and greatly enhances maintainability.

(2) Upper and lower work roller devices: The upper and lower rollers are important components of the plate rolling machine. They are refined forgings. After flaw detection, they are first rough-shaped to leave a machining allowance, then are quenched and tempered, and then finely machined to the specified size and requirements. Finally, the roller surface is heat treated. The journals at both ends of the upper and lower rollers adopt rolling bearings, which have a long service life, save power consumption, improve the main transmission efficiency, and reduce the main transmission power.

(3) Main transmission device: The three rollers of this machine are all driving rollers, driven by a cycloidal reducer, motor, and coupling device. They can rotate forward and reverse to provide power for sheet rolling.

3.Electronic control system

The electrical control system consists of an electrical control cabinet and an operating console. The control electrical appliances of this machine are all installed in the power distribution cabinet. It adopts electrical centralized operation and is easy to operate. The main circuit uses three-phase 380V/50Hz AC power. Three motors drive the work rolls to rotate, and one motor drives the hydraulic pump station, which has short-circuit and overheating protection. The main original components are products from famous domestic manufacturers. Made in strict accordance with national standards, the structure is reasonably arranged and has necessary safety protection measures.

How to operate the sheet plate cone roll bending machine?

1.The feeding of the metal plate is driven by the friction between the metal plate and the work roll. The flat plate is bent into an arc according to the arc formed by the three tangent points in contact with the work roll. The desired height can be achieved by adjusting the tilt and lift of the upper roller. The required arc curvature radius.

2.When rolling: First, make the distance between the lower roller and the upper roller is greater than the thickness of the plate, then place the fan-shaped plate with the plate head in the middle and place it symmetrically on both sides on the lower roller as the basic working position, and gradually press down 2 oil cylinders (note that they are not pressed down simultaneously), operate the work roller to rotate (make the rotation direction consistent with the feeding direction) to bend the middle part of the sheet. According to the radius of curvature, adjust the tilt and lift of the upper roller accordingly, and repeat this for several times. Roll in forward and reverse directions until it closes.The position of the upper roller and the degree of pressing need to be mastered through multiple rolling experiences.

3.When unloading: raise the upper roller to a certain height, and the rolled metal cylinder can be unloaded from one end of the upper roller. At this point, the unloading work is completed.

4.Before rolling, the oxide slag around the unfolded piece should be removed. Do not mishandle the upper and lower rollers to squeeze each other. Excessive pressure may easily cause the taper roller neck to break.

If the two sides of the fan-shaped board are placed asymmetrically, it will easily lead to misalignment and misaligned edges when the final joint is closed. Improper adjustment of the position of the upper roller can easily cause small or large openings to butt first. Specific operations require experience and cannot be expressed in words. It is best for operators with plate rolling experience to operate the test machine.

If there is no pre-bent sector plate edge, you need to roll the two sides first like rolling a straight tube, and finally roll the center to ensure that both sides of the weld are straight, and then put it on the plate rolling machine for schooling after welding.
