[0001] The invention belongs to the technical field of guide bases, and in particular relates to a rolling guide base of a finishing mill and a processing device thereof. Background Art

[0002] Finishing mill is mainly used for fine rolling of metal materials (such as steel, aluminum, etc.). Its purpose is to gradually reduce the thickness of metal materials to the required accuracy and size through repeated rolling processes, while improving the mechanical properties and surface quality of the materials. Finishing mill includes working roll system, support roll system, transmission device, adjustment device, lubrication and cooling system and control system;

[0003] The guide base is an important component in the finishing mill. It is responsible for supporting and fixing the guide device. The guide device is used to guide and stabilize the path of the material during the rolling process to prevent deviation and distortion, thereby ensuring that the material passes through the mill according to the predetermined trajectory. The guide base is usually installed at the entrance and exit of the finishing mill to ensure the correct guidance of the material when entering and leaving the working roll;

[0004] During the high-speed wire production and rolling process, the MA35, MA20 and other guide bases used in the high-speed area are fixed to the roll box panel by two horizontal bolts. As the speed of the finishing mill continues to increase, the impact force of the red steel on the imported rolling guide increases, and the force on the base also increases accordingly. The fixing strength of the two bolts can no longer meet the production requirements, and frequent breakage problems will occur, which will not only increase production failures, but also easily damage the roll box panel, causing more economic losses.

[0056] Preferably, a through hole 3 is provided on the side of the long hole 3 201 at the bottom of the base body 1.

[0057] Preferably, the size of the long hole can be set according to the roller diameter variation range of the roller ring. For example, when used with a 155mm-173mm roller ring, l=33mm, and when used with a 205mm-230mm roller ring, l=43mm. The two long holes on the top, namely the long hole 1 2 and the long hole 200, can be fastened with M20*120 hexagon socket bolts, and the long hole on the bottom, namely the long hole 3 201, can be fastened with M20*55mm hexagon socket bolts.

[0058] The through hole 3 of the M20 bolt can be used with an M20*100 hexagonal bolt and used in conjunction with the long hole below the base, i.e., the fastening bolt of the long hole three 201, to achieve the positioning function of the guide base.

[0059] The working principle and beneficial effects of the above technical solution are as follows: the present invention opens three long holes at corresponding positions on the base body 1 according to the arrangement of the wire holes on the roller box panel, so that the guide base can be fixed to the roller box panel using three bolts, and opens an M20 through hole 3 on the side of the long hole at the bottom, so that the fixing bolt on the long hole 3 201 below the guide base can be used as a positioning block in conjunction with the positioning bolt of the through hole 3 on the side, so as to ensure the positioning accuracy of the guide, and the guide base can be fastened by using three bolts arranged in a triangle to ensure that it will not break during the roller box replacement cycle;

[0060] The design of the three long holes and the through hole 3 ensures the fixing strength of the base body 1, and the fastening bolts will not break during the roller box replacement cycle, which greatly reduces the risk of damage to the steel pile and the roller box. In addition, the present invention has a simple structure and does not require changing the roller box panel structure. The base spare parts can be used after being purchased.

[0061] Example 2

[0064] A plurality of distance sensors, which are evenly arranged on the contact side of the base body 1 and the rolling guide;

[0065] A calculation unit, the calculation unit is electrically connected to the pressure sensor and the distance sensor, and is used to calculate an actual guide calibration prompt warning value within a current monitoring period based on the detection values ​​of the pressure sensor and the distance sensor;

[0066] A control unit and an alarm unit, wherein the control unit is electrically connected to the computing unit and the alarm unit, and the control unit is used to control the alarm unit to give an alarm prompt based on the computing unit;

[0068] Among them, ∈ is the actual guide calibration warning value in the current monitoring period, a1 is the detection value compensation coefficient of the pressure sensor, n is the total number of pressure sensors, N j is the detection value of the jth pressure sensor, e is a natural number, the value is 2.72, a2 ​​is the detection value compensation coefficient of the distance sensor, m is the total number of distance sensors, L i is the detection value of the i-th distance sensor, max(L i ) represents the maximum value among the detection values ​​of several distance sensors;

[0069] The control unit compares the actual guide calibration prompt warning value in the current monitoring period with the preset guide calibration prompt warning value. If the actual guide calibration prompt warning value in the current monitoring period is greater than the preset guide calibration prompt warning value, the control unit controls the alarm unit to issue an alarm prompt.

[0070] The working principle and beneficial effects of the above technical solution are as follows: the design of the calibration prompt module can monitor the fit of the guide installation when installing the guide, so as to ensure the reliability of the subsequent work of the guide. When the detection values ​​of several pressure sensors are uneven, that is, When the difference is large, or the detection value of one of the distance sensors is too large, it proves that the bottom surface of the guide guard is installed unstably or the guide guard is inclined to one side when installed. By calculating the actual guide guard calibration prompt warning value in the current monitoring period, when the actual guide guard calibration prompt warning value in the current monitoring period is greater than the preset guide guard calibration prompt warning value, the control unit controls the alarm unit to issue an alarm prompt. Timely adjustment of the guide guard can effectively ensure the processing accuracy of the finishing mill.
