Operating principle
Three-roll rolling machines are designed for longitudinal bending of sheet metal workpieces. In most applications, the required cross-sectional profile of the preform is specifically designed to allow the machine to bend the metal as needed. In addition to the production of non-closed pipe blanks, these machines can perform cut-off transitions, as well as shallow forming of the ribs of rigidity.
Three-roll rolling machines usually work in a continuous cycle. The sheet is loaded into the gap between the rolls, after which, during their rotation, the metal is bent to the required radius. The transitions considered are usually performed in the cold state.
Modern models of three-roll rolling machines allow processing of workpieces with a thickness of 1−100 mm with a width of 500−8000 mm. All machines have unique functions required for high precision and versatility. The design of the machine provides the installation of rollers in the idea of a triangle, which ensures a good rolling precision.
When rollers and short tubular blanks are rolled out, it is possible to obtain a flat version of the profile finish. It is also possible to pre-bend both ends of the sheet without the need to remove, rotate and reinstall the plate.
The versatility of the equipment can be further expanded by adding a variety of attachments to the work rolls that are installed from the end parts of the tool.
Urgency of application
Three-roll rolling machines work with high speeds of rotation of rolls, for which a set of various gears is provided. Such machines are used in the production of various parts from sheet — trays, troughs, spiral pipes, shells, etc. The main area of application is the production of steel structures for roofing, the construction of ventilation and heating ducts, plumbing communications and other sheet products with relatively small production lots.
Supplier — AvecGlob Company — offers at affordable prices from the manufacturer various models and sizes of three-high-speed rolling machines designed for working with sheet metal. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Design Features
Modern models of three-roll rolling machines differ:
Presence of a hydraulic drive of pressing of rolls with the differentiated effort of pressing ;.
Infinitely adjustable speed of rotation of the lower rolls;
Control of parallelism of both ends of the rolled workpiece, regardless of the working forces of rolling.
To increase the service life, the machines are supplied with spherical bearings, in which working rolls rotate. The finished product is dumped by a special hydraulic cylinder. Modern roller equipment is supplied with an automated tool adjustment system.
Supplier — AvekGlob Company — offers to purchase different sizes of three-roll forming machines intended for obtaining uninterrupted circular cross-sectional blank pieces from sheet metal. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
