Description

Technical Field

[0001] The utility model relates to the technical field of cold rolling roller tempering equipment, in particular to a novel cold rolling roller tempering device. Background Art

[0002] Cold rolling rolls, commonly known as cold rolling rolls or cold rolling work rolls, are the main components of the cold rolling mill and are directly involved in the metal processing process. Cold rolling rolls are generally flat rolls and are mainly used for rolling plates and strips. In a broad sense, cold rolling rolls include working rolls that are in direct contact with the rolled piece and supporting rolls that serve as a support. However, in a narrow sense, cold rolling rolls often refer to cold rolling work rolls. The cold rolling work rolls are required to have sufficient strength, uniform high hardness and good surface quality to withstand extremely high rolling forces, ensure sufficient wear resistance and meet the precision requirements of the rolled materials. Forged steel rolls that can be quenched to high hardness are often used as cold rolling rolls. Cold rolling work rolls will produce large residual stresses during the quenching process. These stresses may cause cracks or deformation of the rolls during use. Tempering treatment can effectively reduce these residual stresses and improve the stability and service life of the rolls. The structure of the cold rolling work rolls after quenching is in an unstable state. Tempering treatment can make the structure more stable and prevent structural changes during use, thereby affecting the performance of the rolls. Because the hardness and strength of the steel after cold rolling are higher, but the brittleness also increases accordingly, which is easy to cause fracture. Tempering treatment can reduce the hardness of the steel while improving the toughness and ductility, making the rolls safer and more reliable during use. The internal residual stress generated during the cold rolling process may cause the rolls to deform or break during use. Tempering treatment can reduce the hardness of the steel while improving the toughness and ductility, making the rolls safer and more reliable during use. Fire treatment can eliminate these residual stresses and reduce the deformation and damage of the rolls. At present, the cold roll tempering heat treatment equipment faces significant structural limitations in actual operation. These limitations directly affect its treatment effect and efficiency. Specifically, due to design deficiencies, the equipment often lacks an effective fixing mechanism when performing the tempering process, resulting in excessively high temperatures in local areas of the workpiece and prone to tilting. This not only aggravates the stress concentration inside the material, but also easily causes quenching cracking problems, making the finished products that should have met the standards become defective products and cannot be recycled, thereby significantly increasing the waste rate of resources. In addition, there is a common problem in the tempering heat treatment devices currently on the market, that is, the lack of flexible adjustment capabilities to adapt to the processing needs of workpieces of different sizes. This design rigidity limits the application range of the equipment, making it unable to meet diversified production needs and difficult to meet the pursuit of efficient and flexible production processes in modern manufacturing. For example, "Utility Model CN214115653U The cold rolling roller tempering heat treatment device is provided with a connecting plate. The arrangement of this component, under the action of the connecting plate, enables the width of the body to be adjusted within a certain range, thereby facilitating the processing of workpieces of different lengths and increasing the practicality of the device; it is also provided with a clamping block and a motor. The arrangement of this component, under the cooperation of the clamping block and the motor, can rotate the processed workpiece, thereby ensuring that the workpiece is heated evenly during heat treatment and increasing the stability of the device. In response to the above problems, technical means to solve them may already exist in the prior art, but this case aims to provide an alternative or replacement technical solution.
