Description

Technical Field

[0001] The utility model relates to the technical field of roll groove crescent groove positioning and measurement, in particular to a roll crescent groove rapid positioning and measurement device. Background Art

[0002] The roll crescent groove is a special design on the roll surface in steel rolling production. Its existence is crucial to ensure the dimensional accuracy, surface quality and stability of the steel during the rolling process. The following is an introduction to the roll crescent groove:

[0003] 1. Crescent grooves are grooves with a certain depth and width arranged along the circumferential direction on the surface of the roll, and are shaped like crescents. These grooves are designed to accommodate excess metal during the rolling process, prevent the edges of the rolled pieces from folding, cracking or excessive deformation at high temperatures, and also help improve the bite conditions of the rolled pieces.

[0004] 2. The geometric parameters of the crescent groove include depth, width and spacing. The setting of these parameters needs to be optimized according to the material, thickness, width and rolling speed of the rolled piece. A crescent groove that is too deep or too wide may cause the surface of the rolled piece to be uneven, while a crescent groove that is too shallow or too narrow may lose its proper function.

[0005] 3. The processing of the crescent groove is usually done by milling, grinding or laser engraving, which requires high-precision processing equipment and strict process control. During the use of the roller, the crescent groove will gradually wear out and needs regular inspection and maintenance, and grinding or replacement of the roller when necessary.

[0006] 4. The effect of the crescent groove is affected by many factors, including the hardness of the roll material, surface roughness, lubrication conditions, and the temperature and material of the rolled piece. Reasonable selection and adjustment of these parameters are very important to give full play to the effect of the crescent groove, extend the service life of the roll and improve rolling efficiency.

[0007] 5. With the development of steel rolling technology, some new design concepts and technologies have been introduced into the optimization of the crescent groove, such as the use of composite materials and coating technology to improve wear resistance, and the use of computer simulation technology to predict and optimize the geometric parameters of the crescent groove to adapt to more complex and demanding rolling conditions.

[0008] At present, the crescent groove milled by the thread milling machine needs to ensure the processing depth size, and the existing base is an inclined flat V-type. The outer circle of the roller is an arc-shaped, and the inclined flat V-type base cannot completely match the roller, and the measurement stability is low. With long-term use, the base wears, and once it is worn, it cannot be accurately measured. The existing table seat is made of ordinary material, which is easy to wear and bump and leave pits.

[0009] Therefore, there is an urgent need to design a rapid positioning and measuring device for the crescent groove of a rolling mill to solve the problem that the existing crescent groove measuring device on the raised stripes of the rolling mill cannot fit the surface of the rolling mill, resulting in poor measurement stability and inaccurate judgment of rolling mill wear, affecting the quality of steel rolling.
