Technical Field

[0001] This utility model relates to the field of I-beam wheels, specifically to a large I-beam wheel made of thin steel plate. Background Technology

[0002] A spool is a tool used to wind metal wire or steel wire rope. Spools for winding steel wire are generally made of steel plate and their parts are connected by welding. The welded joints of the spool are relatively weak and may break after long-term use.

[0003] Technical solution CN219408702U discloses an I-beam wheel, including side flanges and an I-beam wheel cylinder connected between them. Both sides of the I-beam wheel cylinder, at their respective connections to the side flanges, are provided with arc-shaped transition structures. The radius of the arc-shaped transition structures is 0.4 mm. The side flanges, the cylinder, and the arc-shaped transition structures are integrally connected. Both sides of the clamping surface of the cylinder have inwardly opening mounting mating surfaces. The cylinder and side flanges are both made of carbon structural steel. In this solution, the I-beam wheel is directly machined on a lathe, and the material is carbon structural steel, which allows it to withstand long-term operation and improves its service life.

[0004] In technical solution CN219408702U, the H-beam is directly machined by a lathe, which is a complicated process and has a high cost. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is to provide a large H-beam wheel made of thin steel plate.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a thin steel plate type large H-beam wheel, including side flanges, a central through hole and a support tube through hole opened in the side flanges, a central shaft cylinder welded and connected between the two central through holes of the two side flanges, a support tube welded and connected between the two support tube through holes of the two side flanges, and a winding drum shaft connected between the two side flanges and located on the outer periphery of the central shaft cylinder and the support tube. The two side flanges have opposing inner surfaces, and the central through hole and / or the support tube through hole have a punched edge facing the inner surface. The punched edge is welded to the central shaft cylinder and / or the support tube.

[0007] Preferably, in order to enhance the strength of the steel plate around the central shaft cylinder and / or the support tube, the angle between the punched edge and the central shaft cylinder and / or the support tube is 40~70°.

[0008] Preferably, in order to prevent the steel wire reel from deforming due to large axial tension when it is winding up, the edge of the support tube is provided with first reinforcing ribs at intervals around the circumference. The first reinforcing ribs are either convex or concave ribs.

[0009] Preferably, in order to improve the applicability of the I-beam to customer equipment, the end faces of the central shaft cylinder and the support tube are flush with or lower than the outer side of the side flange.

[0010] Preferably, in order to improve the deformation resistance of the side flange, the edge of the side flange is provided with raised ribs.

[0011] Preferably, for ease of welding, at least one of the punched edges is connected to a sleeve portion on its inner edge, one end of which is fixedly connected to the punched edge, and the sleeve portion has an inner wall that abuts against the central shaft and / or the support tube.

[0012] Preferably, for good welding results, the sleeve portion is composed of several segments, and the cuts of the segments extend to the punched edge.

[0013] Preferably, in order to enhance the strength of the flange, the side flange is a rolled flange.

[0014] Preferably, in order to enhance the flange's resistance to deformation, the outer side of the side flange is provided with a central area and an outer peripheral area, the central perforation and the support pipe perforation are located in the central area, and the outer peripheral area is provided with a second reinforcing rib, which is a raised rib or a concave rib.

[0015] The advantages and beneficial effects of this utility model are as follows:

[0016] The center perforation and / or support pipe perforation of the side flange have a punched edge facing inward, which effectively enhances the strength of the surrounding steel plate and prevents the surrounding steel plate from deforming due to large radial force.

[0017] The folded edge facing inward provides a larger welding area between the flange and the central shaft and / or support tube, resulting in a stronger weld and a longer service life for the I-beam. This structure also avoids the need to reserve space for the weld when welding the central shaft and / or support tube to the side flange, thus preventing the end face of the central shaft and / or support tube from protruding from the outer side of the side flange.

[0018] The I-beam wheel has a reasonable structure, low failure rate, is easy to manufacture, and is well-suited to customer machines. Attached Figure Description

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0026] Example 1

[0027] like Figure 1 , 2 As shown, the thin steel plate type large H-beam wheel of Embodiment 1 includes a side flange 1, a central through hole and a support tube 4 through hole opened in the side flange 1, a central shaft cylinder 3 welded between the central through holes of the two side flanges 1, a support tube 4 welded between the support tube 4 through holes of the two side flanges 1, and a winding drum shaft 2 connected between the two side flanges 1 and located on the outer periphery of the central shaft cylinder 3 and the support tube 4. The two side flanges 1 have opposing inner surfaces, and the central through hole and the support tube 4 through hole have punched edges 101 facing the inner surfaces. The punched edges 101 are welded to the central shaft cylinder 3 and the support tube 4.

[0028] Specifically, in this large H-beam wheel made of thin steel plate, the side flange 1 is made of thin steel plate material, and its outer surface is punched to form a central perforation and a perforation of the support tube 4, as well as a corresponding punched edge 101 facing inward. During the manufacturing of this large H-beam wheel made of thin steel plate, the operator first welds the side flange 1 on side a to the central shaft cylinder 3; during welding, flux fills the gap between the punched edge 101 corresponding to the central perforation and the central shaft cylinder 3, without overflowing the outer surface of the side flange 1. Next, the support tube 4 and the winding drum shaft 2 are welded to the side flange 1 on side a in sequence. The inner surface of the side flange 1 on side a is welded to the end face of end a of the winding drum shaft 2. Next, place the side flange 1 on side a flat on the workbench. At this time, the central shaft cylinder 3 stands above the side flange 1 on side a. Place the side flange 1 on side b flat on the central shaft cylinder 3. The end faces of the central shaft cylinder 3 and the support tube 4 pass through the central through hole and the through hole of the support tube 4, respectively, but do not exceed the outer side of the side flange 1 on side b. Weld the side flange 1 on side b to the central shaft cylinder 3 and the support tube 4. After welding, weld the end face of the b end of the winding drum shaft 2 to the inner side of the side flange 1 on side b. The final thin steel plate type large I-beam wheel has no protrusions on the side, and the I-beam wheel has high applicability to customer equipment. The central through hole of the side flange 1 and the through hole of the support tube 4 have punched edges 101 facing inward, which effectively enhances the strength of the surrounding steel plate and prevents the surrounding steel plate from deforming due to large radial force. The folded edge 101 facing inward provides a larger welding area between the side flange 1, the central shaft cylinder 3, and the support tube 4, resulting in a stronger weld and a longer service life for the I-beam wheel. This structure also avoids the need to reserve space for the weld seam when welding the central shaft cylinder 3 and the support tube 4 onto the side flange 1, thus allowing the end faces of the central shaft cylinder 3 and the support tube 4 to protrude from the outer side of the side flange 1.

[0029] Preferably, the angle between the punched edge 101 and the central shaft cylinder 3 and / or the support tube 4 is 40~70°. Specifically, as shown in the figure... Figure 1 , 2 As shown, the punched edge 101 can enhance the strength of the steel plates around the central shaft cylinder 3 and the support tube 4. When the angle between the punched edge 101 and the central shaft cylinder 3 and the support tube 4 is 40~70°, the strengthening effect of the punched edge 101 on the strength of the steel plates around the central shaft cylinder 3 and the support tube 4 is more obvious.

[0030] Preferably, the edge of the perforation in the support tube 4 is provided with first reinforcing ribs 102 at intervals around the periphery. The first reinforcing ribs 102 are either convex or concave ribs. Specifically, the I-beam reel experiences significant axial tension and deformation when winding the steel wire. Providing reinforcing ribs 102 at intervals around the perforation in the support tube 4 enhances the strength of the steel plate surrounding the perforation, preventing deformation of the I-beam reel due to large axial tension during wire winding. Figure 1 , 2 The reinforcing rib 102 is a concave rib.

[0031] Preferably, the end faces of the central shaft cylinder 3 and the support tube 4 are flush with or lower than the outer surface of the side flange 1. Specifically, some wire winding machines have requirements for the shape of the I-beam, that is, the side of the I-beam cannot have protrusions. Therefore, the end faces of the central shaft cylinder 3 and the support tube 4 are set to be flush with or lower than the outer surface of the side flange 1. Figure 1 As shown, the end faces of the central shaft cylinder 3 and the support tube 4 are lower than the outer side of the side flange 1, which can improve the applicability of the I-beam wheel to customer equipment.

[0032] Preferably, the edge of the side flange 1 is provided with raised ribs 103. Specifically, as shown in the example... Figure 1 As shown, the side flange 1 of the thin steel plate type large H-beam wheel is made of thin steel plate, which is prone to axial deformation after impact. The rib 103 on the edge of the side flange 1 can improve the deformation resistance of the side flange 1.

[0033] Preferably, at least one folded edge 101 has a sleeve portion 1011 connected to its inner edge. One end of the sleeve portion 1011 is fixedly connected to the folded edge 101, and the sleeve portion 1011 has an inner wall that abuts against the central shaft cylinder 3 and / or the support tube 4. Specifically, as Figure 3 As shown, the inner edge of the punched edge 101 has a gap with the outer wall of the central shaft cylinder 3 and the support tube 4. When the central shaft cylinder 3 and the support tube 4 are welded to the side flange 1, it is difficult to keep the central shaft cylinder 3 and the support tube 4 perpendicular to the inner side of the side flange 1. However, the sleeve part 1011 is provided with an inner wall that abuts against the central shaft cylinder 3 and the support tube 4, making it easier to keep the central shaft cylinder 3 and the support tube 4 perpendicular to the inner side of the side flange 1.

[0034] Preferably, the sleeve portion 1011 is composed of several segments, the cuts of which extend to the punched edge 101. Specifically, as... Figure 4 As shown, the segmentation is formed by stamping after the side flange 1 is cut, and the cut is produced during this process. When welding the central shaft cylinder 3 and the side flange 1, the flux melts and generates high-temperature fumes. If some air and fumes do not escape from the weld before the flux cools, there will be holes inside the weld, affecting the welding effect. The segmented cut makes it easier for air and fumes to escape from the weld, resulting in fewer holes inside the weld after cooling and a better welding effect.

[0035] Example 2

[0036] The side flange 1 and the second reinforcing rib 104 of Embodiment 2 will be described. In Embodiment 2, components that are identical to those in Embodiment 1 are labeled with the same symbols as in Embodiment 1, and detailed descriptions are omitted. Figure 5As shown, the side flange 1 in Embodiment 2 is a rolled flange, and the outer side of the side flange 1 is provided with a central area and an outer peripheral area. The central through hole and the through hole of the support tube 4 are located in the central area, and the outer peripheral area is provided with a second reinforcing rib 104, which is a concave rib. Specifically, the rolled flange has higher structural strength than the ordinary flange, especially better resistance to torsion. The second reinforcing rib 104 is provided in the outer peripheral area to prevent deformation due to large axial tension when the H-beam reel is winding up the steel wire.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
