Description

Technical Field

[0001] The utility model relates to a lamp used for online detection of iron sticking defects on the roller surface of a straightening roller of a plate straightening machine, and belongs to the technical field of steel rolling equipment. Background Art

[0002] The plate straightening machine is used to release the stress of the plate after rolling and eliminate the unevenness of the steel plate. It is an important equipment on the hot-rolled medium and thick plate production line. Its performance directly determines the quality of the finished plate, and is particularly important for the surface quality of the plate. The surface condition of the straightening roller directly affects the surface quality of the straightened product.

[0003] During the process of straightening the plate, due to reasons such as support roller blocking, high temperature, impact of the head and tail of the steel plate, and roller surface wear, iron oxide powder accumulates and is extruded on the surface of the steel plate during continuous straightening. Some of the iron oxide powder is pressed into the roller surface of the straightening roller, forming an iron sticking defect on the roller surface, which causes indentations or even pits on the surface of the steel plate after straightening, seriously affecting the surface quality of the product.

[0004] The usual solution is to stop the machine and manually check the iron sticking defects on the roller surface and grind them. It is generally difficult to find minor roller surface defects such as iron sticking, pits, and bulges. You can only manually place a flashlight on the roller surface to illuminate the roller surface, so that the tiny defects on the roller surface can be distinguished and displayed. Due to the limitation of the roller gap opening of the straightening machine, the operating space for personnel is small, and the light in the roller gap is not good. The operator can only hold a flashlight in one hand to check and a grinder in the other hand to grind the iron sticking on the roller surface. The disadvantages are high labor intensity, low efficiency, easy fatigue of personnel and safety hazards.

[0005] During the roller surface inspection and grinding process, the straightening roller needs to be manually rotated or inched to conduct a comprehensive inspection and grinding of roller surface defects. Since manual hand-held flashlights are prone to fatigue and the lighting is not fixed, it is easy to miss inspections.

[0006] If an external power lamp or other lighting fixture is used, it cannot be installed and fixed on the surface of the straightening roller that needs to be rotated, and the light of the general lamp is not concentrated, and it cannot form a beam parallel to the surface of the straightening roller. There is a reflection phenomenon on the roller surface, which affects the sight of the operator and is not convenient for finding small and slight iron defects on the roller surface. It is easy to cause missed detection and affect the surface quality of the steel plate. Therefore, it is very necessary to design a plate straightening machine roller surface defect detection lamp that is easy to operate and has good detection effect. Utility Model Content

The upper end position of the upper support arm 8 is located below the upper straightening roller 001.

[0046] The installation angle of the upper arm can be adjusted by changing the overlapping position of the circular through hole 81 of the upper arm 8 and the circular positioning hole 14 of the first substrate 1, so that the upper end of the upper arm 8 is located below different upper straightening rollers 001, so that the light of the flashlight 6 is irradiated along the roller surface of the straightening roller 001.

[0047] The use of the utility model:

[0048] See also Figure 7-9 When it is necessary to check the roller surface of the straightening machine, if the lower straightening layer is checked separately, place the lamp (excluding the upper arm) between two adjacent straightening rollers, so that the roller contacts the roller surface of the straightening roller or the vertical rib above the straightening roller cover is embedded in the positioning groove 18, turn on the flashlight, and then check the roller surface.

[0049] If both the upper and lower straightening rollers need to be inspected, on the basis of the above, it is only necessary to install and fix the flashlight in the rectangular notch of the upper arm and fix it, install the upper arm between the first substrate and the second substrate, and adjust the angle of the upper arm so that the flashlight is below the upper straightening roller. When the number of upper straightening rollers is greater than that of lower straightening rollers, the upper arm remains in a vertical state. When the number of upper straightening rollers is less than that of lower straightening rollers, the upper arm maintains a certain angle, and the upper end is located below the upper straightening roller, so as to ensure that the light is irradiated along the roller surface, which is convenient for rapid inspection of small iron sticking defects on the roller surface.

[0050] The utility model can effectively inspect the roller surface of the straightening machine, improve the inspection efficiency, and avoid the occurrence of missed inspections. The utility model also has the advantages of simple structure, low cost, convenient use, strong versatility, and the like.
