Description

Technical Field

[0002] During the hot rolling production process, some steel coils have different degrees of flat coil phenomenon during the unloading process to the pallet transportation. Flat coil refers to the defect characteristics of hot rolled plate (coil), which is oval at the end of the coil and is easy to occur in thinner coils. This is because the coil diameter of the edge part of the coil is not equal to the coil diameter of the center part, thus forming a flat coil shape. Flat coil not only affects the appearance quality of the coil, but also affects the subsequent processing process, such as affecting the process feeding, and also brings difficulties to shearing, welding, bending and other operations, and may even cause product quality problems.

[0003] In order to control the flatness of the coil, it is necessary to adjust the flatness of the coil in time according to the change of the flatness value, but there is no suitable tool to detect the flatness of the steel coil. Utility Model Content

The detection is convenient and fast, and the adjustment reference value can be quickly read and adjusted, and real-time online detection can be performed. The measuring component extends the measuring block through the measuring rod to measure externally, and the end of the measuring rod can be against the flatness of the steel coil, mainly measuring the inner diameter of the flatness of the steel coil. The inner rod drives the connecting rod and the measuring rod, and the measuring rod can be applied to different steel coils, so that the flatness of the steel coil can be effectively measured. After obtaining the measurement data of the steel coil, the steel coil can be adjusted in time, which also reduces the situation where the subsequent process cannot be loaded due to the flat coil problem, and reduces the secondary repair cost.

Part of the measuring rod 112 is placed in the measuring block 111, and the other part of the measuring rod 112 is located outside the measuring block 111, and the measuring rod 112 can slide relative to the measuring block 111, which is achieved by arranging slots on the surface or both sides of the measuring block 111. The measuring rod 112 and the measuring block 111 are plug-in connected, and the two ends of the connecting rod 113 are respectively hinged to the measuring rod 112 and the first end of the inner rod 121, and the hinge is connected by a pin; the inner rod 121 is slidable relative to the sleeve 122, and the inner rod 121 drives the connecting rod 113 by sliding relative to the sleeve 122, and the connecting rod 113 drives the measuring rod 112 to be retractable, extended or retracted relative to the measuring block 111, and external measurement is performed through the relative position of the measuring rod 112 and the measuring block 111.

[0031] In the embodiment of the present application, a certain distance is formed between the measuring point and the steel coil through the inner rod 121 and the sleeve 122, and the steel coil is directly measured through the measuring component 110, and the reading is taken at a position other than the first end. In this way, measurement can be performed even when the temperature of the steel coil is high. The detection is convenient and quick, and the adjustment reference value can be quickly read to perform real-time online detection. The measuring component 110 extends the measuring block 111 through the measuring rod 112 to measure externally. The end of the measuring rod 112 can abut against the steel coil, and the inner rod 121 drives the connecting rod 113 and the measuring rod 112, so that the measuring rod 112 can be applied to different steel coils.

After obtaining the measurement data of the steel coil, the steel coil can be adjusted in time, which also reduces the situation where the subsequent process cannot be loaded due to the flatness problem, thereby reducing the secondary rework cost.

[0032] In an optional embodiment, the first end of the inner rod 121 is hinged with two connecting rods 113, and there are two measuring rods 112 in total.

The inner diameter of the flat roll of the steel coil can be measured by extending the ends of the two measuring rods 112 into the flat roll of the steel coil and abutting against the flat roll position. This is because the scale position of the inner rod 121 is pre-set, and the extension displacement of each small section of the measuring rod 112 relative to the measuring block 111 corresponds to the scale of the inner rod 121. In this way, the scale of the inner rod 121 can reflect the spacing between the ends of the two measuring rods 112, thereby obtaining the inner diameter of the flat roll of the steel coil.

It is set by welding, threaded clamping or other connection methods. In this way, after the inner rod 121 moves, the thrust spring 115 is subjected to force and can restore its deformation when the inner rod 121 is released, so as to rest against the flat roll of the steel coil.

[0035] In an optional embodiment, the sleeve 122 is provided with a reading window 122a, and the reading window 122a may be an opening on the sleeve 122, or may be made of a transparent material. The reading of the inner rod 121 inside the sleeve 122 may be read through the reading window 122a, and the scale mark position of the inner rod 121 corresponds to the position of the reading window 122a, so that data can be read at the reading window 122a. In an optional embodiment, the second end of the inner rod 121 extends out of the sleeve 122, and the corresponding value can be read through the end of the sleeve 122 corresponding to the scale position of the inner rod 121.

The limit plug 125 can be fixed by welding, threaded connection or other fixing methods, as long as it is ensured to be set at the second end of the inner rod 121. The size of the limit plug 125 is larger than the inner diameter of the sleeve 122, so that the limit plug 125 can always be placed outside the sleeve 122 to prevent the inner rod 121 from entering the sleeve 122 and being unable to be pulled out.
