Description

Technical Field

[0001] The utility model relates to the technical field of steel plate processing measurement, in particular to a device for measuring the width of a heating furnace loading plate. Background Art

[0002] During the sheet metal processing process, unprocessed sheet metal must be transported to the hot rolling mill or designated storage area. Before storage, the dimensions of each sheet metal must be initially measured and recorded in detail to provide accurate data support for subsequent processing steps.

[0003] During the hot rolling process, when sheets enter the heating furnace, sheets of the same size are typically loaded together within a single processing period. This allows the temperature in the heating furnace to be adjusted according to the specific size of the sheets, ensuring that each sheet is heated evenly, thereby improving overall processing quality.

[0004] However, since the size measurement of the blanks when they are stored is usually carried out at room temperature, the temperature of the blanks is relatively low at this time. When the blanks are approaching the heating furnace through the loading device, the ambient temperature around the heating furnace is relatively high, and the blanks may experience a certain degree of thermal expansion, resulting in different degrees of changes in the width of the blanks with the same size specifications originally measured. As a result, the pre-set heating strategy of the heating furnace cannot guarantee the heating effect of the blanks, affecting the processing quality of the blanks. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a device for measuring the width of the blank for loading into the heating furnace, which can measure the width of the blank before and after entering and exiting the heating furnace, facilitating data comparison so as to better adjust the heating strategy of the heating furnace.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for measuring the width of a loading plate of a heating furnace, comprising a front measuring component installed on a loading rack and a discharging measuring mechanism installed on a discharging rack, the loading rack and the discharging rack are respectively located at the feeding end and the discharging end of the heating furnace body, the front measuring component comprises a loading measuring mechanism and a feeding measuring mechanism, the loading measuring mechanism is located at an end of the loading rack away from the heating furnace body, the feeding measuring mechanism is located at an end of the loading rack close to the heating furnace body, and the discharging measuring mechanism is located at an end of the discharging rack close to the heating furnace body.

[0007] Furthermore, the feeding and measuring mechanism is a visual camera, and is installed above the end of the feeding rack away from the heating furnace body through a mounting bracket.

[0008] Furthermore, the feed measurement mechanism is a laser rangefinder, and is installed above the loading rack near one end of the heating furnace body through a mounting bracket.

[0009] Furthermore, a first high-temperature airflow protective cover is provided on a side of the feed measuring mechanism close to the heating furnace body, and the first high-temperature airflow protective cover is fixedly connected to the mounting frame of the feed measuring mechanism.

[0010] Furthermore, the discharge measuring mechanism is an infrared rangefinder or a thermal imaging camera, and is installed above the discharge rack near one end of the heating furnace body through a mounting bracket.

[0011] Furthermore, a second high-temperature airflow protective cover is provided on a side of the discharge measuring mechanism close to the heating furnace body, and the second high-temperature airflow protective cover is fixedly connected to the mounting frame of the discharge measuring mechanism.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This heating furnace loading sheet metal width measuring device can measure the width of the sheet metal before and after entering and exiting the heating furnace through the loading measuring mechanism, the feeding measuring mechanism and the discharging measuring mechanism. By comparing the measurement data, the thermal expansion amplitude of the sheet metal after heating can be analyzed, thereby facilitating the adjustment of the heating furnace heating strategy to better achieve the heating effect of the sheet metal.

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] See also Figure 1 A device for measuring the width of a sheet metal for loading a heating furnace comprises a front measuring assembly installed on a loading rack 1 and a discharging measuring mechanism 6 installed on a discharging rack 2. The loading rack 1 and the discharging rack 2 are respectively located at the feeding end and the discharging end of a heating furnace body 3. The front measuring assembly comprises a loading measuring mechanism 4 and a feeding measuring mechanism 5. The loading measuring mechanism 4 is located at an end of the loading rack 1 away from the heating furnace body 3, the feeding measuring mechanism 5 is located at an end of the loading rack 1 close to the heating furnace body 3, and the discharging measuring mechanism 6 is located at an end of the discharging rack 2 close to the body of the heating furnace body 3.

[0018] like Figure 1As shown, the structure of the device for measuring the width of the blank for loading materials in the heating furnace is similar to that of the existing device for measuring the width of the blank for loading materials in the heating furnace. The main improvement of the device is to improve the measurement effect of the blank. Figure 1 As shown, when the heating furnace feeding sheet width measuring device of the present invention is in use, the sheet transported from the feeding rack 1 to the heating furnace body 3 can be measured by the feeding measuring mechanism 4, thereby detecting the width data of the sheet to be heated. Subsequently, in the process of gradually moving the sheet toward the heating furnace body 3, it is affected by the heat diffused from the heating furnace body 3, and the temperature of the sheet rises slightly and expands. Before the sheet is about to enter the interior of the heating furnace body 3, it is again measured by the feeding measuring mechanism 5. The width of the sheet metal is measured, and then after the sheet metal is heated at high temperature by the heating furnace body 3, when the high-temperature sheet metal moves from the heating furnace body 3 to the discharge rack 2, the width of the heated sheet metal is measured by the discharge measuring mechanism 6, and the width data of the sheet metal in three stages can be obtained. By comparing the thermal expansion ratio data of the sheet metal in the database, it can be determined whether the heating furnace body 3 has fully heated the sheet metal, so as to more accurately adjust the heating strategy of the heating furnace body 3 and improve the heating effect of the heating furnace body 3 on the sheet metal.

[0019] like Figure 1 As shown, the feeding measurement mechanism 4 is a visual camera, which is installed above the end of the feeding rack 1 away from the heating furnace body 3 via a mounting bracket. Since the feeding measurement mechanism 4 is installed at the end of the feeding rack 1 away from the heating furnace body 3, where the temperature is generally lower, the visual camera can be used as the feeding measurement mechanism 4 to perform more comprehensive data measurement of the sheet metal on the feeding rack 1. This is not limited to width measurement, and can also measure the thickness, length, and width of the sheet metal. At the same time, it can also determine whether there is any foreign matter on the sheet metal surface, thereby improving the stability of the feeding operation.

[0020] like Figure 1 As shown, the feed measurement mechanism 5 is a laser rangefinder, which is mounted on the upper side of the loading rack 1 near the end of the heating furnace body 3. The temperature of the sheet metal at the feed inlet of the heating furnace body 3 is relatively high before the sheet metal is about to enter the heating furnace body 3. Using a laser rangefinder as the feed measurement mechanism 5 can more accurately measure the width of the sheet metal.

[0021] like Figure 1 As shown, a first high-temperature airflow shield 7 is provided on the side of the feed measurement mechanism 5 near the heating furnace body 3. The first high-temperature airflow shield 7 is fixedly connected to the mounting bracket of the feed measurement mechanism 5. The first high-temperature airflow shield 7 can block the high-temperature airflow emanating from the feed inlet of the heating furnace body 3, preventing the high-temperature airflow from causing high-temperature damage to the internal feed measurement mechanism 5. The first high-temperature airflow shield 7 can be made of high-temperature resistant and explosion-proof glass, and covers the feed measurement mechanism 5 inside for high-temperature protection.

[0022] like Figure 1 As shown, the discharge measurement mechanism 6 is an infrared rangefinder or thermal imaging camera, mounted on a mounting bracket above the discharge rack 2 near the end of the heating furnace body 3. Because the sheet metal is extremely high just after exiting the heating furnace body 3, the high-temperature radiation from the sheet metal surface can affect the detection of a conventional rangefinder. Using an infrared rangefinder or thermal imaging camera as the discharge measurement mechanism 6 allows for more accurate width measurement of the hot sheet metal.

[0023] like Figure 1 As shown, a second high-temperature airflow shield 8 is provided on the side of the discharge measuring mechanism 6 near the heating furnace body 3. The second high-temperature airflow shield 8 is fixedly connected to the mounting bracket of the discharge measuring mechanism 6. The second high-temperature airflow shield 8 can block the high-temperature airflow emanating from the discharge port of the heating furnace body 3 and the high temperature of the high-temperature sheet metal surface, thereby preventing the high-temperature discharge measuring mechanism 6 from being damaged by high-temperature heat. The second high-temperature airflow shield 8 can be made of high-temperature resistant and explosion-proof glass, and covers the discharge measuring mechanism 6 inside for high-temperature protection.

[0024] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention.
