Abstract

This utility model relates to the field of high-speed wire production and testing technology, and in particular to a thermal inspection device with inlet and outlet conduits. It includes a thermal inspection mechanism and two conduit mechanisms respectively located at its inlet and outlet. Each conduit mechanism includes a wire conduit and an annular air head connected to one end of the wire conduit. The ends of the two wire conduits away from the annular air heads extend to the inlet and outlet of the thermal inspection mechanism, respectively. The two wire conduits are positioned at the inlet and outlet of the thermal inspection mechanism by conduit fixing mechanisms and are located on the same straight line. This utility model, by separating the inlet and outlet conduit mechanisms and the thermal inspection mechanism, allows for adjustment of the height of the thermal inspection mechanism.

Description

Technical Field

[0001] This utility model relates to the field of high-speed wire production and testing technology, and in particular to a thermal inspection device with inlet and outlet conduits. Background Technology

[0002] During high-speed wire rod production line rolling, to improve product surface quality, a thermal inspection device is usually installed between the water tanks after the reducing and sizing mill. Its main function is to scan the surface of the rolled piece for defects such as peeling and scabbing using its built-in high-temperature detection lens. Through its high-efficiency detection, it can effectively intercept and stop the machine when defects are found on the surface of the rolled piece, thereby avoiding quality accidents.

[0003] The hot eye is equipped with four high-temperature detection lenses evenly distributed in a 360-degree spatial ring. The inlet and outlet guide tubes are fixedly installed on the hot eye body, with their center lines coinciding with the axis formed by the four high-temperature detection lenses and with the center lines of the front and rear heat-conducting grooves (i.e., the rolling line) to ensure smooth rolling.

[0004] In actual production, the four high-temperature detection lenses can only ensure accurate detection if the rolled piece runs along the (virtual) trajectory of the rolling line. Otherwise, the distance between the rolled piece surface and the four evenly distributed high-temperature detection lenses in a 360-degree spatial ring will be uneven, directly affecting the transmission of detection signals. However, due to the weight of the rolled piece, when producing ultra-large specifications of 13mm or more, the rolled piece will run close to the bottom of the guide tube and deviate from the rolling line (the axis formed by the four high-temperature detection lenses), causing the top lens to be unable to effectively detect the upper surface of the rolled piece and thus failing to effectively intercept surface defects.

[0005] As mentioned above, in typical hot-eye designs, the inlet and outlet conduits are fixedly mounted on the main body. When the phenomenon of the rolled wire running tightly against the bottom of the conduit is observed, the axis formed by the four high-temperature detection lenses must be adjusted accordingly. Against this backdrop, it is essential to design an inlet and outlet conduit device capable of stably guiding ultra-large diameter, high-speed wire into the specified position for precise hot-eye detection. Utility Model Content

[0006] To address the aforementioned technical issues, this utility model provides a thermal inspection device with inlet and outlet conduits. By separating the inlet and outlet conduit mechanism from the thermal inspection mechanism, the height of the thermal inspection mechanism can be adjusted when the rolled piece inside the thermal inspection mechanism falls due to its own weight. This facilitates the acquisition of images of the wire from four directions by the four inspection lenses, effectively preventing ultra-large-diameter high-speed wire from falling when entering the thermal inspection due to its own weight, thus avoiding errors in wire inspection data.

[0007] This solution includes a thermal eye detection device with inlet and outlet conduits, comprising a thermal eye detection mechanism and two conduit mechanisms respectively located at its inlet and outlet. Each conduit mechanism includes a wire conduit and an annular air head connected to one end of the wire conduit. The ends of the two wire conduits away from the annular air head extend to the inlet and outlet of the thermal eye detection mechanism, respectively. The two wire conduits are respectively positioned at the inlet and outlet of the thermal eye detection mechanism by a conduit fixing mechanism and are located on the same straight line.

[0008] Furthermore, the inner wall of the annular air head is provided with a number of air holes in a ring shape, and each air hole is connected to an air guide connector through an air passage, and the other end of the air guide connector is connected to an air guide tube.

[0009] Furthermore, the air duct located at the inlet side of the thermal eye detection mechanism is connected to an external air source, and the air duct located at the outlet side of the thermal eye detection mechanism is connected to an external negative pressure generating device.

[0010] Furthermore, the conduit fixing mechanism includes two conduit fixing bodies with guide grooves, which position the wire conduit in the guide grooves.

[0011] Furthermore, the two catheter fixation bodies are connected by bolts to form a single unit.

[0012] Furthermore, the two catheter fixing bodies are pressed together into a single unit by a handwheel screw assembly.

[0013] Furthermore, the thermal eye detection mechanism is equipped with pads at the four corners of its bottom.

[0014] Furthermore, the thermal imaging detection mechanism is equipped with four entrance-side cameras arranged in pairs facing each other.

[0015] The beneficial effects of this utility model are as follows: This utility model has a thermal eye detection device for inlet and outlet guide tubes. By separating the inlet and outlet guide tube mechanism and the thermal eye detection mechanism, the height of the thermal eye detection mechanism can be adjusted when the rolled piece inside the thermal eye detection mechanism falls due to its own weight. This is beneficial for the four detection lenses to collect images of the wire from four directions, which can effectively avoid the problem of errors in wire detection data caused by the falling of ultra-large specification high-speed wires when entering the thermal eye due to their own weight.

Detailed Implementation

[0021] The thermal imaging device with inlet and outlet conduits provided in this embodiment is as follows: Figure 2 As shown, the device includes a thermal inspection mechanism 203 and two guide tube mechanisms respectively located at its inlet and outlet. It can be understood that the guide tube mechanisms can also be mounted on other guide tube mechanisms to achieve positioning and guidance of the rolled piece. See also... Figure 1 The conduit mechanism includes a wire conduit 101 and an annular air head 103 connected to one end of the wire conduit 101. The annular air head 103 has several air holes in a ring shape on its inner wall, and each air hole is connected to an air guide connector 104 through an air passage. The other end of the air guide connector 104 is connected to an air guide pipe 102. The air guide pipe 102 located on the inlet side of the thermal eye detection mechanism 203 is connected to an external air source, which can be an air pump. The air guide pipe 102 located on the outlet side of the thermal eye detection mechanism 203 is connected to an external negative pressure generating device, which can be a vacuum pump or a fan.

[0022] Two of the wire conduits 101 extend from the ends away from the annular air head 103 to the inlet and outlet of the thermal eye detection mechanism 203, respectively. The two wire conduits 101 are positioned at the inlet and outlet of the thermal eye detection mechanism 203 by the conduit fixing mechanism, and are located on the same straight line.

[0023] like Figure 3 As shown, the conduit fixing mechanism includes two conduit fixing bodies 206 with guide grooves. The two conduit fixing bodies 206 position the wire conduit 101 in the guide grooves. The two conduit fixing bodies 206 are pressed together as a whole by a handwheel and screw assembly 205. The handwheel and screw assembly 205 includes a column and a clamping screw pressing mechanism connected to the column. The handwheel is rotated to drive the screw to rotate, thereby pressing the two conduit fixing bodies 206. This is a conventional clamping screw structure, which will not be described in detail here.

[0024] See Figure 4The thermal inspection unit 203 is equipped with four entrance-side cameras 801, which are arranged in pairs to take pictures of the wires passing through the thermal inspection unit 203. An exit-side light-collecting mirror 802 is set in the exit direction of the thermal inspection unit 203 to reflect light to the direction of the four entrance-side cameras 801.

[0025] In some specific implementations, shims can be added to the four corners of the bottom of the thermal imaging mechanism 203 to adjust its height. By using different numbers or thicknesses of the shims, the distance between the two entrance side cameras 801 and the upper and lower surfaces of the wire can be adjusted in real time.

[0026] Understandably, the conduit mechanism is installed on both sides of the inlet and outlet of the hot eye. The wire conduit 101 of the device is fixed by a conduit fixing body 206 of customized size. At the same time, the end of the wire conduit 101 is slightly inserted into a certain position at both ends of the inlet and outlet of the hot eye detection mechanism 203 and fixed therein. In addition, the inlet side wire conduit 101 supplies air to the inlet side air pipe 102 of the device through an external air source. The gas is sprayed out by the annular air head 103 to cool the wire passing through, and at the same time blows the water droplets of the water-cooled wire back into the water-cooled wire to avoid damage to the equipment due to excessive temperature and to prevent moisture from entering the hot eye device. The outlet side wire conduit 101 is connected to the annular air head 103 to absorb dust and other impurities brought out by the wire passing through the inside of the hot eye, reduce equipment detection interference, and extend the service life of the device.

[0027] Specifically, such as Figure 2 As shown, this device is used between the water-cooled line and the sizing line during high-speed wire rod production line rolling. Not only can guide tube mechanisms be arranged on both sides of the hot eye detection mechanism 203, but the aforementioned guide tube mechanism can also be used at the heat equalization guide groove 204 in the straight direction. Both are fixed by handwheel screw assembly 205. The oversized wire rod 201 will pass through the hot eye detection inlet 202 and the hot eye detection mechanism 203. During this process, the quality of the rolled wire is inspected. The improvement of the device avoids the production inspection problems caused by the oversized wire rod falling due to its weight and deviating from the position of the rolling line when using the hot eye detection device, which greatly saves production adjustment time.

[0028] In addition to the above embodiments, this utility model may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
