Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel plate welding technology, specifically to a vertical welding device for hot-rolled steel plates. Background Technology
[0002] Hot-rolled steel sheet is a type of steel sheet produced by heating steel ingots to a high temperature and then hot-rolling them. This process is typically carried out at temperatures between 900℃ and 1250℃, giving the steel good ductility and allowing it to be easily processed into various specifications and thicknesses. Because the steel is formed during hot rolling, the surface of the finished product is usually relatively rough, often containing defects such as oxide scale, and therefore often requires subsequent treatments such as spraying and polishing.
[0003] The main characteristics of hot-rolled steel sheets are high strength, good toughness, and the ability to withstand large external forces, thus exhibiting excellent performance in mechanical impact and vibration environments. Their production cost is relatively low, making them suitable for large-scale production, and therefore they are widely used in construction, bridges, ships, vehicles, and machinery.
[0004] When hot-rolled steel plates are used to manufacture structures requiring vertical connections (such as support columns, steel frames, etc.), two hot-rolled steel plates need to be vertically welded. Currently, most methods for vertical welding of hot-rolled steel plates involve spot welding or clamping to initially fix the two plates. However, spot welding leaves weld points that require subsequent cleaning, which can easily affect the quality of the welded area. Furthermore, when clamping steel plates, clamp components often cover the edges of the welding area, requiring the middle portion of the steel plate to be welded first, the clamp disassembled, and then the edges welded. To solve the aforementioned problems, a vertical welding device for hot-rolled steel plates is provided. Utility Model Content

[0024] 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.
[0025] Please see Figure 1-5 This embodiment provides a vertical welding device for hot-rolled steel plates, including a base 1, which has an inverted T-shaped structure, such as... Figure 1 and Figure 2 As shown, the base 1 comprises two vertically connected plates manufactured using a one-piece molding technique (mold casting). This design not only enhances the structural strength of the base 1 but also ensures its high stability and precision during long-term use. The mold casting technique allows for precise dimensional control and consistency, reducing welding problems caused by manufacturing errors. Furthermore, this one-piece molding technique significantly enhances the tensile strength and durability of the entire structure, making it suitable for withstanding greater workloads.
[0026] like Figure 1 As shown, clamping plates 2 are installed on both plates of the base 1, and the two clamping plates 2 are vertically distributed. Specifically, multiple limiting rods 3 are fixedly connected to the two edges of the end faces of the plates, and the limiting rods 3 are symmetrically arranged on both sides. The clamping plate 2 includes a side plate 21, a rotating plate 22, and a spring 23. The two sides of the side plate 21 are slidably sleeved on the limiting rods 3, and the limiting rods 3 keep the side plate 21 parallel to the plates of the base 1. This design can effectively maintain the parallelism of the side plate 21 and reduce welding deviations during the welding process. The design of the limiting rods 3 ensures that the clamping plate 2 is accurately clamped during the welding process.
[0027] like Figure 3 As shown, one end of the rotating plate 22 is rotatably connected to a side plate 21, and the other end of the rotating plate 22 is slidably inserted with a screw 221. The other side plate 21 has a screw hole. After rotating the rotating plate 22 so that one end of the rotating plate 22 with the screw 221 is attached to the other side plate 21, the screw 221 is aligned with the screw hole of the side plate 21. After the screw 221 is threadedly connected to the side plate 21 through the screw hole, the rotating plate 22 can be fixed so that the two side plates 21 and the rotating plate 22 are on the same horizontal plane.
[0028] like Figure 1 and Figure 2As shown, spring 23 is sleeved on limiting rod 3. Spring 23 applies a spring force to side plate 21 towards base 1, causing rotating plate 22 to fit against base 1. The design of spring 23 ensures the stability of the welding fixture while effectively absorbing external impact force (converting the impact force into its own compressive potential energy), improving the uniformity of clamping force, making the two hot-rolled steel plates more firmly welded, and avoiding misalignment caused by vibration or external force. The function of spring 23 allows clamping plate 2 to maintain appropriate pressure during long-term welding, thereby ensuring the stability of hot-rolled steel plates and preventing the weakening of clamping force from affecting the welding effect.
[0029] like Figure 5 As shown, taking the vertical rotating plate 22 as an example, the upper and lower ends of the rotating plate 22 are provided with inclined surfaces. The hot-rolled steel plate can be inserted between the rotating plate 22 and the base 1 through the inclined surfaces of the rotating plate 22. During the insertion of the hot-rolled steel plate, the side plate 21 and the rotating plate 22 will move away from the base 1, and the spring 23 will be compressed. After the two hot-rolled steel plates are inserted, one side of the two hot-rolled steel plates will be in contact with each other. The rotating plate 22 applies pressure to the hot-rolled steel plate through the elastic force of the spring 23, which, together with the base 1, clamps and fixes the hot-rolled steel plate. The inclined surface design makes the insertion of the hot-rolled steel plate smoother, reduces component damage caused by improper insertion, ensures perfect docking of the two hot-rolled steel plates, and improves clamping efficiency. The continuous pressure applied by the spring 23 helps to firmly clamp the hot-rolled steel plate in the ideal position during the welding process, reduces the possible displacement of the steel plate during welding, and thus ensures the uniformity and reliability of the welding quality.
[0030] The mating edges of the two hot-rolled steel plates fixed on the base 1 are located at the angle between the two plates of the base 1, between the gaps of the clamping plates 2. At this time, the connection between the two hot-rolled steel plates can be welded through the gaps of the clamping plates 2 (gas shielded welding or manual arc welding, manual arc welding is commonly used).
[0031] After welding is completed, rotate screw 221 to disengage it from side plate 21. At this time, rotating plate 22 can be rotated. After the two rotating plates 22 rotate, they interlock and fit together, exposing the welded hot-rolled steel plate, which can then be removed from base 1.
[0032] Compared to existing vertical welding of hot-rolled steel plates, spot welding leaves weld points that require subsequent cleaning, which can easily affect the quality of the welded area. Furthermore, the fixture can intrude into the welding area of the hot-rolled steel plate (components can easily cover the edges of the welding area, requiring the middle part of the steel plate to be welded first, the fixture disassembled, and then the edges welded). This embodiment uses clamping plate 2 to fix two closely fitting hot-rolled steel plates, exposing the joint and facilitating a one-time, complete welding process.
[0033] The two hot-rolled steel plates to be welded are mostly of equal length. During welding, the two plates need to be aligned. To align them, a positioning rod 4 is slidably installed at the included angle between the two plates of the base 1. For example... Figure 1 and Figure 4 As shown, a sliding frame 41 is fixedly connected to the included edge of the base 1, and a positioning rod 4 is slidably inserted into one end of the sliding frame 41. In use, the positioning rod 4 is slid out, and the weld edges of the two hot-rolled steel plates are aligned and fitted against one end of the positioning rod 4. The flat end of the positioning rod 4 aligns the two hot-rolled steel plates. The design of the positioning rod 4 effectively improves the precision of the hot-rolled steel plate butt joint, ensuring accurate positioning of the welding area before welding and avoiding welding defects caused by misalignment.
[0034] During welding, move the positioning rod 4 to retract it into the sliding frame 41, so that the positioning rod 4 is separated from the hot-rolled steel plate. At this time, the two vertical hot-rolled steel plates can be welded.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
