Description

Technical Field

[0001] This utility model relates to the field of casting roll technology, specifically a casting roll strength testing device. Background Technology

[0002] Rolls are the main working parts and tools on a rolling mill that cause continuous plastic deformation of metal. A roll is mainly composed of a roll body, a roll neck, and a shaft end. The roll body is the middle part of the roll that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The roll neck is installed in a bearing and transmits the rolling force to the mill stand through the bearing housing and the pressing device. The drive end shaft end is connected to the gear housing through a connecting shaft, which transmits the rotational torque of the motor to the roll. Rolls can be arranged in two-roll, three-roll, four-roll, or multi-roll configurations in the mill stand. During the roll production process, in order to ensure that the produced rolls meet the hardness requirements, it is necessary to test the hardness of the cast steel parts. Therefore, the demand for a roll hardness testing device is increasing.

[0003] In response, Chinese patent application number CN214584506U discloses a roll hardness testing device, including a first vertical box and a testing machine. A gravity plate is fixedly connected to the bottom end face of the first vertical box, and a roller is fixedly connected to the inner side of the bottom end face of the gravity plate. A rotating rod is rotatably connected to the inner side of the left end face of the first vertical box, and a first bevel gear is fixedly connected to the right end face of the rotating rod. A second bevel gear is meshed with the top face of the first bevel gear, and a threaded rod is fixedly connected to the inner side of the second bevel gear. A second vertical box is threadedly connected to the outer side of the threaded rod, and the second vertical box is slidably connected to the first vertical box. In this invention, the height can be adjusted, making it suitable for testing different roll production lines. It avoids secondary movement of the rolls, reduces the labor intensity of workers, can test the hardness of rolls at any position, and is easy to disassemble and install, reducing space occupation and facilitating storage and organization.

[0004] However, existing strength testing devices for cast rolls may experience displacement at both ends of the roll due to pressure during the strength testing process, causing the detector to slip on the roll surface, which in turn affects the accuracy of the test to some extent.

[0005] Therefore, in order to solve the above problems, a strength testing device for casting rolls is proposed. Utility Model Content
