Description

Technical Field

[0001] This utility model relates to the technical field of coil defect quantification device, specifically a device for quantifying edge tightness defects of cold rolled coil. Background Technology

[0002] During the high-speed rolling of aluminum sheet and strip, the deformation area of ​​the roll gap is affected by friction and the heat generated by the strip deformation, resulting in uneven thermal expansion deformation of the rolls. As the strip coil diameter increases and the rolling time is extended, the uneven thermal protrusion of the roll shape gradually increases, eventually causing a tight edge defect at the edge of the coil. That is, the edge of the coil tightens towards the central axis of the coil, forming a conical edge. There is no dedicated device for quantifying tight edge defects in the existing technology, making it difficult to quantify them. This results in some coil defects being too large, affecting the use by downstream customers and leading to quality complaints from them. Utility Model Content

[0003] The main objective of this invention is to provide a device for quantifying edge tightness defects in cold-rolled coils, thereby solving the problem that the prior art lacks a dedicated device for quantifying edge tightness defects, making it difficult to quantify these defects. This results in some coils having excessively large defects, affecting downstream customers' use and leading to quality complaints from them.

[0004] To achieve the above objectives, this utility model provides a device for quantifying tight edge defects in cold-rolled coils, including a base plate, a right-angled triangle, and a ruler. The base plate has a groove, and the right-angled triangle is slidably connected to the groove, with one right-angled side of the triangle located within the groove. A ruler groove parallel to the groove is provided on one side of the groove, and the ruler is engaged within the groove. Scales are provided on the rear side of the right-angled triangle near its hypotenuse and on the upper surface of the ruler. The right-angled triangle slides within the groove, allowing measurement of the height of the tight edge defect, while the ruler measures the length of the defect. Furthermore, the ruler, being engaged within the groove, facilitates replacement when the scale on its surface wears down.

[0005] Furthermore, the right end of the base plate is connected to the right end of the top rod via a connecting rod. The top rod is parallel to the base plate and located above the right-angled triangle ruler. The left end of the top rod is fixedly connected to an end plate perpendicular to the top rod. The sliding groove and the ruler groove are set in the left-right direction. The base plate is used for positioning from the bottom surface of the roll material, and the top rod and the end plate are used for positioning from the side surface of the roll material, thereby making the measurement data of the right-angled triangle ruler and the ruler more accurate and faster.

[0006] Furthermore, the zero mark of the ruler is located directly below the left side of the end plate; the zero mark of the right-angled triangle is aligned with the upper surface of the base plate; the positions of the zero marks of the ruler and the right-angled triangle facilitate quick reading, and no conversion is required after reading.

[0007] Furthermore, the connecting rod is fixedly connected to a handle.

[0008] The cold-rolled coil edge tightness defect quantification device of this utility model can quickly measure and quantify tightness defects, perform measurement and quality inspection of tightness defects, and pick out unqualified products with serious tightness defects, thereby ensuring product quality and reducing quality complaints from downstream customers.

[0012] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0013] like Figures 1 to 3 As shown, according to an embodiment of the present invention, a device for quantifying edge tightness defects of cold-rolled coil is provided for measuring edge tightness defects of cold-rolled coil 8. The device includes a base plate 1, a right-angled triangle ruler 2, and a ruler 3. The base plate 1 has a length, width, and height of 200mm, 10mm, and 20mm, respectively. A groove 101 is provided on the base plate 1, and the right-angled triangle ruler 2 is slidably connected to the groove 101. The three angles of the right-angled triangle ruler 2 are 30°, 60°, and 90°, respectively. The length of the longer right-angled side of the right-angled triangle ruler 2 is 150mm, and the longer right-angled side is located within the groove 101. A ruler groove 102 parallel to the groove 101 is provided on one side of the groove 101, and the ruler 3 is engaged within the ruler groove 102. Scales are provided on the rear side of the right-angled triangle ruler 2 near the hypotenuse and on the upper surface of the ruler 3.

[0014] The right-angle triangle ruler 2 slides in the slide groove 101, which can measure the height H of the tight edge defect, and the ruler 3 can measure the length L of the tight edge defect; and the ruler 3 is stuck in the ruler groove 102, which makes it easy to replace when the scale on the ruler surface is worn.

[0015] The right end of the base plate 1 is connected to the right end of the top rod 4 via the connecting rod 5. The top rod 4 is parallel to the base plate 1 and located above the right-angle triangle ruler 2. The left end of the top rod 4 is fixedly connected to the end plate 6, which is perpendicular to the top rod 4. The sliding groove 101 and the ruler groove 102 are arranged in the left and right directions.

[0016] The base plate 1 is used for positioning from the bottom surface of the roll material, and the top rod 4 and end plate 6 are used for positioning from the side surface of the roll material, so that the measurement data of the right angle triangle ruler 2 and ruler 3 are more accurate and faster.

[0017] The zero mark of ruler 3 is located directly below the left side of end plate 6; the zero mark of right triangle ruler 2 is aligned with the upper surface of base plate 1; the positions of the zero marks of ruler 3 and right triangle ruler 2 facilitate quick reading, and no conversion is required after reading.

[0018] The connecting rod 5 is fixedly connected to the handle 7.

[0019] The working principle of the above embodiments is as follows: The edge of the cold-rolled coil 8 has a tight edge defect, that is, the edge of the coil tightens towards the central axis of the coil, and the edge of the coil forms a cone shape; When measuring edge tightness defects, place the cold-rolled coil 8 on the bracket, with the bottom center of the cold-rolled coil 8 in contact with the bracket and the sides suspended; press the base plate 1 of the cold-rolled coil edge tightness defect quantification device against the lowest end of the cold-rolled coil 8, and press the end plate 6 against the side of the cold-rolled coil 8; push the right-angle triangle ruler 2 towards the cold-rolled coil 8, and stop when it cannot be pushed further; read the value of the edge tightness defect length through the ruler 3, and read the value of the edge tightness defect height through the right-angle triangle ruler 2.

[0020] The cold-rolled coil edge tightness defect quantification device in this embodiment can quickly measure and quantify tightness defects, completing the measurement of a cold-rolled coil every 10 seconds on average. This allows for the measurement and quality inspection of tightness defects, identifying and removing substandard products with severe tightness defects, thereby ensuring product quality and reducing quality complaints from downstream customers.

[0021] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
