In the field of jewelry production, precision and efficiency are important standards for measuring the level of craftsmanship. As a professional equipment, Hasung jewelry rolling mill is gradually becoming an indispensable tool for many jewelry craftsmen and manufacturers. It occupies an important position in the jewelry making industry with advanced technology, excellent performance, and wide applicability. ​

1.Brand background and R&D philosophy

Hasung’s subsidiary, Shenzhen Huasheng Precious Metal Equipment Technology Co., Ltd., has been deeply involved in the research and development, production, and sales of precious metal automation products for many years. The company was formerly known as Shenzhen Huajie Jewelry Equipment Co., Ltd. Since its establishment in 2014, it has always adhered to the principle of “technology first, quality first”. On the basis of a profound understanding of industrial automation systems, advanced technologies are applied to processes such as precious metal and alloy melting, casting, and wire making and sheet production. The jewelry rolling mill developed by it aims to provide highly automated and high-precision electromechanical integrated equipment for the jewelry industry, meeting the dual needs of efficient production and precise craftsmanship in the industry. ​

2.Analysis of Working Principle

The Hasung jewelry rolling mill mainly achieves the pressing of metal materials through two opposing rotating rollers. When the metal material is fed between the rollers, the strong pressure applied by the rollers causes plastic deformation of the metal material, thereby achieving the goal of changing its thickness and shape. ​

(1)Roll system: As the core component of the rolling mill, the roll is made of high hardness special materials. For example, some models of rolling rolls have a hardness of HRC64 degrees or higher. This high hardness characteristic allows the rolling rolls to withstand tremendous pressure, ensuring that they do not easily deform during the pressing process, thereby ensuring that the metal sheet produced is uniformly thick and highly accurate. Taking a 120mm wide metal sheet as an example, its left-right deviation can be controlled within 0.005mm, and the front back deviation is within 0.002mm, providing high-precision basic materials for jewelry production. ​

(2)Transmission and regulation system: The equipment adopts a multi-stage transmission mode, and multiple transmission structures cooperate with each other to ensure that the speed of the rolling mill is moderate, effectively preventing possible jamming during the pressing process. At the same time, by synchronizing connecting rod gears and other devices, the distance between the rollers can be precisely controlled to ensure uniform and consistent thickness of the processed metal. The rolling mill is also equipped with a high-precision dial, with accurate readings. One rotation of the handle is 1mm, and one small grid is 0.01mm. The operator can accurately adjust the roller spacing according to actual needs to obtain the desired thickness of the metal sheet.

(3)Lubrication and cooling system: In order to ensure the stability and reliability of the equipment during long-term operation, the Hasung jewelry rolling mill is equipped with an automatic oiling and lubrication system. This system can continuously and accurately lubricate key parts such as the sliding bearings of the rolling mill, without the need for manual lubrication, which not only improves work efficiency but also reduces equipment wear caused by improper lubrication. Some large rolling milles also use electric gear pumps to continuously supply oil circulation cooling to the rolling mill sliding bearings, effectively reducing the temperature during equipment operation and extending the service life of the equipment.
