Technical Field
[0001] The utility model relates to the technical field of high-speed wire rod production in the metallurgical industry, and specifically relates to a high-speed wire rod precision turning water-cooled sliding guide device. Background Technique
[0002] The high-speed wire rod rolling mill production line is the main model currently used for high-speed wire rod production in China. Its main production process flow is billet loading, heating, rough rolling, medium rolling, pre-finishing rolling, finishing rolling, water cooling, laying head, Stelmor air cooling line, coiling, P / F line, trimming, packing, weighing, uncoiling, and warehousing. The main function of the finishing mill unit is to precisely form the incoming material from the pre-finishing mill unit and roll out the final finished product that meets the national standard requirements. Therefore, the rolling force of each rolling mill in this unit is in a normal design state. However, due to the fast speed of the rolled piece inside the finishing mill and the fast deformation rate of the rolled piece, after undergoing large deformation rolling through 8 - 10 passes in a short time, the temperature of the rolled piece will rise sharply, resulting in the growth of metal grains and affecting the mechanical properties of the metal after rolling. Moreover, due to the increase in the temperature of the rolled piece, the thickness of the scale on the surface of the rolled piece becomes thicker, which will also affect the performance of the final product.
[0003] During the use of the existing sliding guide device, it is unable to effectively control the temperature rise of the rolled piece during the rolling process in the finishing area, nor can it inhibit the growth of metal grains of the rolled piece and the thickening of the surface scale thickness. At the same time, it is not convenient to adjust the use height after installation and cannot meet the use requirements. Therefore, a high-speed wire rod precision turning water-cooled sliding guide device is provided. Content of the Utility Model

[0021] Embodiment 1:
[0022] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown in the figures, the present invention provides a high-speed wire finishing water-cooled sliding guide device, which includes a rear shell 1 of the finishing water-cooled guide group box. A finishing water-cooled guide group plug-in 4 is arranged on the front surface of the rear shell 1 of the finishing water-cooled guide group box. A front shell 6 of the finishing water-cooled guide group box is arranged on the front surface of the finishing water-cooled guide group plug-in 4. A fixed seat 5 and a connecting seat 7 are fixedly connected to the front and back surfaces of the finishing water-cooled guide group plug-in 4 from left to right in sequence. A guide box water inlet hole 17 is opened at the central axis of the front surface of the front shell 6 of the finishing water-cooled guide group box.

A tongue is fixedly connected to one side of the finishing water-cooled guide group plug-in 4. A fixed block 2 is connected to the central axis of the back surface of the rear shell 1 of the finishing water-cooled guide group box through a screw 3.
[0023] Specific functions of this technical solution: By providing cooling water to the front shell 6 of the finishing water-cooled guide group box, the rolled piece is cooled by the cooling water to avoid the temperature rise of the rolled piece, which can effectively control the temperature of the rolled piece during the rolling process in the finishing area, inhibit the growth of the rolled piece metal grains and the thickening of the surface scale thickness, and also solve the accident of the elbow impacting the guide due to the unreasonable design of the guide (far from the roll ring) and the influence brought by the accident, so as to achieve the purpose of improving the final mechanical properties of the product, increasing the production operation rate and reducing the production cost. A tongue is designed at the middle position on the left side of the finishing water-cooled guide group plug-in 4. During normal assembly, the tongue extends into the roll ring groove to ensure that the rolled piece enters the high-speed wire finishing water-cooled sliding guide group in the first time after leaving the roll ring groove, reducing the steel piling accident caused by the head elbow of the rolled piece hitting the high-speed wire finishing water-cooled sliding guide group with a far distance.
[0024] Embodiment 2:
[0025] Based on the first embodiment, the present utility model is as follows Figure 1 , Figure 2 , Figure 4 and Figure 5 shown. On both sides of the bottom of the rear shell 1 of the finish rolling water-cooled guide guard group box and the front shell 6 of the finish rolling water-cooled guide guard group box, brackets 9 are fixedly connected. On one side of the bracket 9, a housing 10 is provided. On the right side of the housing 10, a motor 11 is fixedly connected. The output end of the motor 11 is fixedly connected with a first crankshaft 19. On the left side of the surface of the first crankshaft 19, a driving gear 12 is fixedly connected. Behind the driving gear 12, a driven gear 13 is meshed. Inside the cavity of the driven gear 13, a second crankshaft 14 is fixedly connected. On the left side of the surfaces of the first crankshaft 19 and the second crankshaft 14, a connecting rod 15 is movably connected. On the front and back of the connecting rod 15, cross bars 16 are fixedly connected. On both sides of the top of the cross bar 16, it is fixedly connected with the bracket 9. Inside the cavity of the cross bar 16, a sliding rod 18 is slidably connected. The bottom of the sliding rod 18 is fixedly connected with the housing 10. On one side of the connecting rod 15, a movable groove is opened. The right side of the second crankshaft 14 is movably connected with the housing 10 through a bearing. On the bottom of the front and back of the housing 10, mounting blocks are fixedly connected, and mounting holes are opened on the top of the mounting blocks.
[0026] Specific function of this technical solution: Start the motor 11. The motor 11 drives the first crankshaft 19 to rotate. The first crankshaft 19 drives the driving gear 12 to rotate. The driving gear 12 drives the driven gear 13 to rotate. The driven gear 13 drives the second crankshaft 14 to rotate, thereby driving the connecting rod 15 to move. The connecting rod 15 drives the cross bar 16 to move. The cross bar 16 drives the bracket 9 to move, thus facilitating the adjustment of the working height.
[0027] Working principle: By supplying cooling water to the front shell 6 of the finish rolling water-cooled guide guard group box, the rolled piece is cooled by the cooling water to prevent the temperature of the rolled piece from rising. It can effectively control the temperature of the rolled piece during the rolling process in the finish rolling area, inhibit the growth of the metal grains of the rolled piece and the thickening of the surface scale thickness. It also solves the accident of the elbow impacting the guide guard and causing steel piling due to the unreasonable design of the guide guard and its far distance from the roll ring, as well as the impact brought by the accident. Thus, the purpose of improving the final mechanical properties of the product, increasing the production operation rate, and reducing the production cost is achieved. A tongue is designed at the middle position on the left side of the finish rolling water-cooled guide guard group plug-in 4. During normal assembly, the tongue extends into the roll ring groove to ensure that the rolled piece enters the finish rolling water-cooled sliding guide guard group immediately after leaving the roll ring groove, reducing the steel piling accident caused by the impact of the elbow of the rolled piece head on the finish rolling water-cooled sliding guide guard group with a relatively long distance.
[0028] Start the motor 11. The motor 11 drives the first crankshaft 19 to rotate. The first crankshaft 19 drives the driving gear 12 to rotate. The driving gear 12 drives the driven gear 13 to rotate. The driven gear 13 drives the second crankshaft 14 to rotate, thereby driving the connecting rod 15 to move. The connecting rod 15 drives the cross bar 16 to move. The cross bar 16 drives the bracket 9 to move, thus facilitating the adjustment of the working height.
