Description

Technical Field

[0001] The present application relates to the field of inlet guides for high-speed bar finishing mills, and in particular to a guide base for inlet guides for high-speed bar finishing mills. Background Art

[0002] The bar mill is a kind of equipment that usually uses the two-roll rolling process to process metal materials. It can transform metal bars into different shapes and sizes, and it occupies an important position in the metal processing industry. The guide is a device installed on the mill before and after the roll hole. Its function is to help the rolled piece enter and exit the roll hole accurately and stably according to the predetermined direction and state. At present, many steel companies use a production process called high-speed bar production in order to use the world-class steel rolling technology to improve the dimensional accuracy and appearance quality of the finished product and to reduce production costs. This production process can effectively improve the production speed of the bar production line. Usually, this high-precision mill using the high-speed bar process is called a high-speed bar finishing mill. In order to ensure the production stability of high-speed production, the guide installed on the finishing mill is not only required to be stable, but also needs to be easy to adjust the position to ensure that the processed object, such as red steel, can accurately align the rolling groove on the roll to enter the roll hole. At present, the guide is mostly installed on the mill body by screws. Although the guide is stable, it is inconvenient to adjust the position. Utility Model Content

[0028] The present application is further described in detail below in conjunction with the accompanying drawings.

[0029] The embodiment of the present application discloses a guide base for an inlet guide of a high-speed bar finishing mill, which is used to adjust the position of the guide to ensure that the processed object can accurately enter the hole of the roller, and also needs to ensure the stability of the guide.

[0030] Reference Figure 1 and Figure 2 A guide base for the inlet guide of a high-speed bar finishing mill comprises a base body 1, the base body 1 is connected to the finishing mill, and the guide base is connected to the finishing mill. Figure 1 Specifically, a docking hole 11 is opened on the base body 1, and a connecting bolt 12 is arranged in the docking hole 11. By opening a threaded hole on the finishing mill, the connecting bolt 12 can be connected to the threaded hole to firmly connect the finishing mill and the base body 1; in addition, the finishing mill and the base body 1 are also commonly connected with a key 13 for making the connection between the finishing mill and the base body 1 more stable.

[0031] Reference Figure 1 and Figure 2 The base body 1 is provided with an adjustment mechanism 2, which is connected to the guide and is used to adjust the position of the guide; the base body 1 is also provided with a clamping mechanism 3, which is used to clamp the guide to prevent it from moving.

[0032] Reference Figure 1 and Figure 2 The adjustment mechanism 2 includes a slider 21. The base body 1 is provided with a slide groove 22, which is arranged horizontally. The slider 21 is slidably arranged on the inner wall of the slide groove 22. The slider 21 can move left and right in the slide groove 22. The slider 21 is used to connect with the guide, so the slider 21 and the guide can move left and right synchronously. A connecting hole 23 is provided in the slider 21, which is arranged horizontally. A connecting column 24 is arranged in the connecting hole 23. The connecting column 24 is threadedly connected to the connecting hole 23. The right end of the connecting column 24 extends to the external environment and is connected to a nut 25.

[0033] Rotating the nut 25 can drive the connecting column 24 to rotate, thereby driving the slider 21 to move left and right. The left and right movement of the slider 21 will drive the guide to move left and right to fine-tune the position of the guide.

[0034] Reference Figure 1 and Figure 2 In order to ensure that the connecting column 24 does not rotate under normal conditions and thus ensure the stability of the guide, a pad 26 is provided on the right end of the base body 1. The material of the pad 26 is preferably a high-strength steel plate. A receiving hole 261 is opened on the pad 26. The receiving hole 261 is in the direction of the connecting column 24, and the connecting column 24 is inserted into the receiving hole 261; a pressure spring 27 is provided between the pad 26 and the nut 25, one end of the pressure spring 27 is provided on the pad 26, and the other end of the pressure spring 27 is provided on the nut 25.

[0035] After the nut 25 is rotated, the pressure spring 27 applies a force in the axial direction of the connecting column 24 to the pad 26 so as to press the thread on the connecting column 24 against the thread on the connecting hole 23 , thereby ensuring the stable movement of the slider 21 .

[0036] Reference Figure 1 and Figure 2 The clamping mechanism 3 includes a pressing plate 31, and an abutting groove 32 is opened on the base body 1. The lower end of the pressing plate 31 is clamped on the inner wall of the abutting groove 32, and the upper end of the pressing plate 31 is used to abut against the guide; a T-shaped receiving groove 33 is also opened at the upper end of the base body 1, and a clamping hole 311 is opened on the pressing plate 31. A bolt rod 34 is passed through the clamping hole 311. The left end of the bolt rod 34 extends into the T-shaped receiving groove 33 and is connected to a bolt head 35. The bolt head 35 abuts against the T-shaped receiving groove 33. The other end of the bolt rod 34 is threadedly connected with a nut 36, and the nut 36 abuts against the pressing plate 31.

[0037] The nut 36 can be removed by twisting it, and then the bolt rod 34, the bolt head 35 and the pressure plate 31 can be easily removed to release the pressure on the guide.

[0038] Reference Figure 1 The abutment groove 32 is a V-shaped groove; one end of the pressure plate 31 located in the abutment groove 32 is an abutment end 312, and the abutment end 312 is arc-shaped; there is a gap between the clamping hole 311 and the bolt rod 34.

[0039] The present application can tighten the guide after fine-tuning: first loosen the nut 36, then fine-tune the guide, and then fine-tune the position of the pressure plate 31 to ensure that the pressure plate 31 is pressed on the guide, at this time the bolt rod 34 and the pressure plate 31 will be fine-tuned together, and then tighten the nut 36 to ensure that the pressure plate 31 is tightened and thus the guide is tightened.

[0040] Reference Figure 1 In order to guide the object to be processed flowing out of the self-guide so that the object to be processed can enter the hole type of the rolling roller stably and accurately, a guide base for the inlet guide of a high-speed bar finishing mill also includes a nose cone 4, which is arranged on the guide. The nose cone 4 is used to accurately guide the object to be processed flowing out of the self-guide. The specific structure of the nose cone 4 is the existing technology and will not be repeated here.

[0041] The implementation principle of a guide base for the inlet guide of a high-speed bar finishing mill in the embodiment of the present application is as follows:

[0042] Loosen the nut 36, rotate the nut 25 to drive the connecting column 24 to rotate, thereby driving the slider 21 to move left and right. The left and right movement of the slider 21 drives the guide to move left and right to fine-tune the position of the guide, fine-tune the position of the pressure plate 31 to ensure that the pressure plate 31 is pressed tightly on the guide, and retighten the nut 36 to ensure that the pressure plate 31 presses the guide.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
