Technical Field
[0001] This utility model relates to the field of steel metallurgical equipment technology, specifically a multi-specification split-type conveying guide trough. Background Technology
[0002] Guide grooves: In the rolling of structural steel, guide grooves guide the workpiece into or out of the rolling mill, ensuring that the workpiece is rolled accurately and stably in a predetermined direction and state. If the guide grooves are worn or deformed, it can lead to steel piling accidents during the workpiece's journey, affecting production safety. The condition of the guide grooves directly affects the mill's operating rate; good guide groove maintenance helps reduce rolling scrap and improve mill operating rate. By improving guide groove design and materials, maintenance workload and frequency can be reduced, thereby lowering production costs. The performance and maintenance of guide grooves have a direct impact on the production efficiency and product quality of the steel rolling mill. Therefore, the importance and management of guide grooves are an indispensable part of the steel rolling process.
[0003] There are a total of 155 conveyor guides between the pre-finishing and finishing mills of wire rod in the rolling mill. They need to be replaced every two months. If the guides are severely worn and not replaced, it will cause the risk of steel piling up. When replacing them, the entire guide needs to be replaced. Since the guide weighs about 25-30 kg, replacing a guide requires a lot of manpower, material resources and time. When replacing the new guide, the rolling line also needs to be corrected, and there are also high spare parts costs. Utility Model Content
[0004] The purpose of this utility model is to provide a multi-specification split conveyor guide to solve the problem of 155 conveyor guides between the pre-finishing and finishing mills of wire rod in a rolling mill, which need to be replaced every two months. If the guides are severely worn and not replaced, it will cause the risk of steel accumulation. When replacing them, the entire guide needs to be replaced. Since the guide weighs about 25-30 kg, replacing a guide requires a lot of manpower, material resources and time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-specification split-type conveying guide trough, comprising a guide trough seat, a wear-resistant core component, a positioning screw, and a limiting seat. A square groove is formed in the center of the conveying guide trough seat, and limiting seats are fixedly connected to the left and right ends of the square groove. A wear-resistant core component is provided between the left and right limiting seats.
[0006] The left and right ends of the wear-resistant core abut against the limiting seat. The wear-resistant core is concave and fits tightly against the inner wall of the groove. The wear-resistant core is composed of several connecting plates spliced together. One end of the connecting plate has vertically arranged sliding grooves symmetrically opened on the front and rear sides. The other end is connected to an extension part that cooperates with the sliding groove. The extension part fits tightly against the inner wall of the sliding groove. The front and rear ends of the connecting plate are symmetrically opened with positioning holes. The front and rear ends of the groove have threaded through holes corresponding to the positions of the positioning holes. A positioning screw is screwed into the threaded through hole. The positioning screw passes through the bottom end of the groove and abuts against the inner wall of the positioning hole.
[0007] Preferably, it also includes a pressure plate, symmetrically arranged at the front and rear ends of the top of the groove. The bottom end of the pressure plate is tightly fitted with the top of the groove. Through holes are symmetrically opened on the left and right ends of the pressure plate. A threaded hole is opened at the top of the groove corresponding to the position of the through hole. A screw is provided in the threaded hole.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1: Please refer to Figure 1-4 This utility model provides an embodiment of a multi-specification split-type conveying guide trough, comprising a guide trough seat 1, a wear-resistant core component 2, a positioning screw 3, and a limiting seat 5. The conveying guide trough seat 1 has a square groove in the middle, measuring 280*70mm. The guide trough seat 1 is the basic component of this structure, used to accommodate other parts and form the support frame of the entire guide trough device. It supports the wear-resistant core component 2, the limiting seat 5, and other components, providing support and fixation. The left and right ends of the square groove are respectively fixedly connected to the limiting seats 5. The limiting seats 5 prevent the wear-resistant core component 2 from sliding beyond a predetermined range. The wear-resistant core component 2 is positioned between the left and right limiting seats 5.
[0022] The left and right ends of the wear-resistant core 2 abut against the limiting seat 5. The wear-resistant core 2 is concave and fits tightly against the inner wall of the groove. The concave shape of the wear-resistant core 2 ensures a tight fit with the inner wall of the groove on the guide slot seat 1, increasing friction. It is composed of multiple connecting plates. During installation, the extension of the connecting plate is aligned with the slide groove of another connecting plate, and the connecting plate is pressed down. The extension slides in the slide groove, and the two connecting plates fit tightly together. After installation, the upper and lower ends of the extension are flush with the upper ends of the slide groove. When the wear-resistant core 2 wears, the worn part is removed, and a new wear-resistant core 2 is installed. No modification to the guide slot seat 1 is required. The entire component can be replaced, facilitating the installation and replacement of worn wear-resistant core 2, thus reducing consumption costs. Wear-resistant core 2 is composed of several connecting plates spliced together. The extension of any connecting plate engages with the groove of another connecting plate, ensuring a tight fit at the joint after splicing. One end of each connecting plate has symmetrically arranged vertical grooves on both sides, and the other end is connected to an extension that engages with the groove, fitting tightly against the inner wall of the groove. The front and rear ends of each connecting plate also have symmetrically arranged positioning holes 201, which engage with positioning screws 3 to prevent the wear-resistant core 2 from shifting or sliding during use. Threaded through holes are provided at the front and rear ends of the groove corresponding to the positions of the positioning holes 201. Positioning screws 3 are screwed into the threaded through holes. Positioning screws 3 are used to fix the connection between the wear-resistant core 2 and the guide slot seat 1. By screwing on the positioning screws 3, the external thread of the positioning screw 3 cooperates with the internal thread of the threaded through holes, allowing the positioning screw 3 to penetrate the guide slot seat 1 and then abut against the inner wall of the positioning hole of the wear-resistant core 2, ensuring that the wear-resistant core 2 does not shift within the guide slot seat 1. The bottom end of the positioning screw 3 penetrates the groove and abuts against the inner wall of the positioning hole 201.
[0023] It also includes a pressure plate 4, symmetrically arranged at the front and rear ends of the top of the groove. The bottom end of the pressure plate 4 is tightly fitted with the top of the groove. The pressure plate 4 is used to further prevent the wear-resistant core 2 from shifting, so that the wear-resistant core 2 is always kept in the installed position. The left and right ends of the pressure plate 4 are symmetrically provided with through holes. The top of the groove is provided with a threaded hole corresponding to the position of the through hole. A screw is provided in the threaded hole. The screw passes through the pressure plate 4 and the bottom end is screwed into the threaded hole and tightened by a nut. Through the tightening of the screw and the nut, the pressure plate 5 can effectively press and fix the wear-resistant core 2, and facilitate later maintenance and adjustment, thereby installing and removing the worn wear-resistant core 2. The corresponding end faces of the pressure plate 4 extend towards the vertical end of the wear-resistant core 2. The extended end does not exceed the end of the wear-resistant core 2 away from the inner wall of the groove, so that the pressure plate 4 can position and press the top of the wear-resistant core 2, further ensuring the stability of the wear-resistant core 2 after installation.
[0024] The wear-resistant core 2 has a U-shaped inner part, and the U-shaped end abuts against the rolled piece.
[0025] During installation, align the extension of the connecting plate with the groove of another connecting plate, press down the connecting plate, and the extension slides in the groove. At the same time, the two connecting plates fit tightly together. After installation, the upper and lower ends of the extension are flush with the upper ends of the groove. Then, install it between the two limiting seats 5. The left and right ends of the wear-resistant core 2 fit and abut against the limiting seats 5. At the same time, install the positioning screw 3 and screw it in so that its top end abuts against the inner wall of the positioning hole on the connecting plate. Then, install the pressure plate 5 at the top of the groove to further limit the wear-resistant core 2. When the wear-resistant core 2 is worn, remove the worn part and then install a new wear-resistant core 2.
[0026] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
