Characteristics of cold pipe rolling machine
Operation theory of cold rolling mill with more than 2 rollers
As shown: Drive by the main motor, Via the reducer, Brace connecting Rod structure to drive rocker system (OABCD) to do swing movement, thus, the upper and lower connecting rods drive the nose sleeve and the roller Frame to make regular reciprocating straight movement along the rolling line. The difference between their reciprocating straight travel is the rolling travel, a period of reciprocating movement, roller No 3 rolls on slide NO 4 and the pass formed by the three roller is regulated by the slide curve to complete a change of “Big-small-big”. When the taper Die is maximum, the roller does not contact with the Shell 2. At this time, the shell rotates at a specified angle and pushes forward a specified Length by the feeding Structure. After that, the pass gradually becomes smaller, to the taper DIE is the smallest, complete the finished Size of wall thickness, Inner and Outer diameter. The continuous completion of such a cycle, to achieve the tube shell Rolling.

Overview


Our Cold Rolling Pipe Mill with More Rollers is a revolutionary piece of equipment that sets new standards in pipe manufacturing technology. The multi - roller architecture of this mill is a game - changer, offering significant advantages over conventional pipe rolling methods.


The multiple rollers are carefully calibrated and arranged in a specific configuration to provide a balanced and controlled rolling force. This setup ensures that the pipe blank is uniformly compressed and shaped, resulting in pipes with consistent quality throughout the production run. The mill's construction is based on heavy - duty materials and advanced manufacturing techniques, guaranteeing its durability and ability to operate continuously under high - load conditions.


The control system of the Cold Rolling Pipe Mill with More Rollers is based on the latest automation technology. It features an intuitive human - machine interface (HMI) that allows operators to easily input production parameters and monitor the rolling process in real - time. The system also incorporates advanced sensors and feedback mechanisms that can detect and correct any deviations from the set parameters, ensuring the production of pipes with the highest level of precision.


Features


Advanced Process Control

The Cold Rolling Pipe Mill with More Rollers comes with an advanced process control system. This system can precisely regulate the temperature, speed, and pressure during the rolling process. By maintaining optimal process conditions, the mill can produce pipes with excellent mechanical properties, such as high tensile strength and ductility. The ability to control these parameters accurately also reduces the occurrence of defects, such as cracks and uneven wall thickness, improving the overall yield of the production process.


Enhanced Material Compatibility

This mill is designed to work with a wide variety of materials, including carbon steel, alloy steel, copper, and aluminum. The multi - roller configuration provides better material deformation control, allowing for the production of high - quality pipes from different metals and alloys. Whether it's for general - purpose pipes or specialized pipes for high - end applications, this mill can handle the material requirements with ease.


Quick - change Tooling System

To increase production flexibility, the Cold Rolling Pipe Mill with More Rollers is equipped with a quick - change tooling system. This system enables operators to change the rollers and other tooling components rapidly, reducing downtime between different production runs. With this feature, manufacturers can quickly switch from producing one type of pipe to another, responding promptly to market demands and increasing production efficiency.


Intelligent Maintenance System

An intelligent maintenance system is integrated into the mill, which uses sensors and data analytics to monitor the condition of critical components. This system can predict potential failures in advance, allowing for scheduled maintenance and reducing unexpected breakdowns. By ensuring timely maintenance, the mill's service life is extended, and production disruptions are minimized, resulting in cost savings for the manufacturer.


Applications


Marine Industry

In the marine industry, pipes are exposed to harsh saltwater environments and extreme mechanical stresses. The Cold Rolling Pipe Mill with More Rollers can produce pipes made from corrosion - resistant materials that are suitable for use in shipbuilding, offshore platforms, and marine pipelines. The high - precision and consistent quality of the pipes ensure reliable performance in marine applications, reducing the risk of leaks and failures that could lead to environmental disasters or costly repairs.


Power Generation

The power generation industry requires pipes for steam turbines, boilers, and cooling systems. Pipes produced by our Cold Rolling Pipe Mill with More Rollers can meet the stringent requirements of this industry. The mill's ability to produce pipes with high mechanical strength and excellent dimensional accuracy makes it possible to manufacture pipes that can withstand high temperatures and pressures in power plants. Additionally, the pipes' smooth surface finish reduces fluid resistance, improving the overall efficiency of the power generation systems.


Oil and Gas Downhole Applications

For oil and gas downhole operations, pipes need to have exceptional strength and durability to withstand the high pressures and corrosive substances present underground. The Cold Rolling Pipe Mill with More Rollers can produce pipes with customized wall thicknesses and internal profiles that are specifically designed for downhole applications. The precise control over the rolling process ensures that the pipes have consistent quality, enhancing the safety and productivity of oil and gas extraction operations.
