Description

Technical Field

[0001] The utility model relates to the technical field of hot-rolled wire rod measurement, in particular to a hot-rolled wire rod measurement device. Background Art

[0002] Hot rolled wire rod is made of square billet (mainly continuous casting billet) as raw material. After heating, it is rolled into $5-17mm long strip wire by rough rolling unit, intermediate rolling unit and finishing rolling unit, and then the wire rod is sized to about 1.1m in a continuous circle by a spinning machine. The shaped wire rod is cooled to the set temperature through a Stelmor road and collected into a coil by a coiler.

[0003] Hot rolled wire rod is mainly used for subsequent processing into various wire products. Due to different transportation methods and production equipment, in order to maximize the benefits, there are different requirements for the coil diameter and length of the wire coil. The inner / outer diameter and length of the hot rolled wire rod are usually measured with a tape measure. Due to the uneven surface of the hot rolled wire rod, the measurement error of the inner / outer diameter and length of the hot rolled wire rod is large, resulting in reduced measurement accuracy.

[0004] Therefore, the utility model provides a hot-rolled wire rod measuring device. Utility Model Content

DETAILED DESCRIPTION

[0024] The following is a further description of the method of use of the present invention in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figures 1 to 3 As shown, a hot-rolled wire rod measuring device comprises:

[0026] The main support 1 is slidably connected with two sliders, namely the first slider 2 and the second slider 3, wherein one side of the two sliders has a parallel abutment portion 4, which is used to abut the hot-rolled wire rod, and the other side of the two sliders has an extension portion 5 arranged in line with the abutment portion 4; the abutment portion 4 and the extension portion 5 can be welded to the first slider 2 and the second slider 3 by welding, and the abutment portion 4 and the welding portion are in line to ensure the measurement accuracy. And the length of the abutment portion 4 is greater than the extension portion 5, and both are perpendicular to the main support 1.

[0027] A laser rangefinder 6 is installed on the extension portion 5 on the first sliding block 2 ; the laser rangefinder 6 can be installed on the first sliding block 2 by means of bolt connection.

[0028] The extending portion 5 on the second slider 3 is provided with a reflective film 7 for reflecting the optical fiber of the laser rangefinder 6 .

[0029] The main support 1 comprises:

[0030] A first branch pipe 11, to which the first slider 2 is connected;

[0031] A second branch pipe 12, one end of which is slidably connected to the first branch pipe 11 and slides inside the first branch pipe 11;

[0032] The third branch pipe 13 is slidably connected to the other end of the second branch pipe 12 and slides outside the second branch pipe 12 . The second slider 3 is connected to the third branch pipe 13 .

[0033] The first branch pipe 11, the second branch pipe 12 and the third branch pipe 13 are square pipes respectively.

[0034] It should be noted that, since the main support 1 is retractable, it can be applied to hot-rolled wire rod packaging shapes of different sizes. When measuring the hot-rolled wire rod packaging shapes of different sizes, a 20×20×2100mm square stainless steel square tube can be selected for production.

[0035] The first branch pipe 11 is provided with a first knob 111, and the third branch pipe 13 is provided with a second knob 131. The first knob 111 and the second knob 131 are used to fix the first branch pipe 11 and the third branch pipe 13, fix the main support 1, and adapt to the packaging shape of hot-rolled wire rods of different sizes.

[0036] The first slider 2 is provided with a third knob 21, and the second slider 3 is provided with a fourth knob 31. The third knob 21 and the fourth knob 31 are used to fix the first slider 2 and the second slider 3 on the main bracket 1, and prevent the first slider 2 and the second slider 3 from sliding and driving the abutment portion 4 to move when measuring, thereby causing inaccurate measurement.

[0037] Working process: When measuring the hot-rolled wire rod, first, adjust the length of the main bracket 1 according to the size of the hot-rolled wire rod, and slide the first branch pipe 11 and the third branch pipe 13 on the second branch pipe 12. After adjusting to the approximate length, fix the first branch pipe 11 and the third branch pipe 13 on the second branch pipe 12 by turning the first knob 111 and the second knob 131, thereby fixing the main bracket 1.

[0038] Subsequently, the abutment 4 on the first slider 2 and the second slider 3 on the main bracket 1 are placed in the hot-rolled wire rod, and then the first slider 2 is fixed on the first branch pipe 11 by turning the third knob 21, and the second slider 3 on the third branch pipe 13 is moved. The movement of the second slider 3 drives the abutment 4 and the extension 5 on the second slider 3 to move. When the abutment 4 is in close contact with the inside of the hot-rolled disk, the second slider 3 is fixed on the main bracket 1 by turning the fourth knob 31, so that the laser rangefinder 6 on the extension 5 on the second slider 3 emits a laser and irradiates it on the extension 5 on the first slider 2. Since the extension 5 on the first slider 2 is affixed with a reflective film 7, the reflective film 7 will reflect the laser, so that the laser rangefinder 6 measures the distance between the two extensions 5, thereby measuring the length or inner and outer diameters of the hot-rolled disk.

[0039] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
