Description

Technical Field

[0001] This utility model relates to the field of uncoiler technology, and in particular to an uncoiler for welded pipe equipment. Background Technology

[0002] An uncoiler is a specialized piece of equipment for metal sheet leveling lines. It is used for placing metal coils and feeding them to the next process. It can be configured into uncoiling, leveling, and shearing production lines and other metal sheet processing production lines according to relevant processing requirements. It is suitable for industries such as steel, automobile, chemical, metallurgy, electronics, rail transportation, construction machinery, food machinery, textile machinery, air conditioning, elevator, building machinery, environmental protection machinery, and advertising decoration. When welding steel coil materials into tubular structures, the steel coil needs to be uncoiled and then re-coiled laterally into a tubular structure. Then, the edges on both sides of the steel sheet are welded to form a tubular structure.

[0003] The existing publication number CN220311354U discloses an uncoiling machine for welded pipe equipment. By setting up a coiling component one, three shaping components and a coiling component two in cooperation, it is convenient to coil flat steel sheet material into a tubular structure. Finally, the tubular material is fed into the welded coiling tube for shaping, exposing the two ends of the steel sheet to the welding hole. This facilitates simultaneous welding when the steel pipe structure passes through the welded coiling tube, thus improving welding efficiency.

[0004] However, during the implementation of this solution, since the first coiling assembly, the three shaping assemblies, and the second coiling assembly are all in a fixed state, they cannot be replaced. In actual factory production, due to different customer needs, steel pipes of different sizes need to be formed. Since this solution cannot meet the processing of multiple types of steel pipes, the effect is poor and the applicability is low, making it unsuitable for actual factory use. Therefore, an uncoiling machine that can form a variety of steel pipes and is suitable for the actual production use of welded pipe equipment in factories is proposed. Utility Model Content

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: an uncoiler for welded pipe equipment, including an uncoiler body 2 for uncoiling coiled steel sheets. This is existing equipment and will not be discussed in detail here. A base 1 is fixedly connected to one side of the uncoiler body 2. A first coiling cone 4 and a second coiling cone 7 are provided on the base 1 for shaping the steel sheets into steel pipes. A weld seam (not shown in the figure) is opened on the surface of the second coiling cone 7 away from the support component 3, which provides an insertion space for the welding component. A welding component (not shown in the figure) is provided at the end of the second coiling cone 7 away from the first coiling cone 4 to weld the butt joint. This has been described in detail in the prior art and will not be discussed here.

[0021] Two symmetrically arranged winding rollers 5 are provided between winding cone 1 4 and winding cone 2 7. The cross-section of winding roller 5 is hourglass-shaped, which further reduces the diameter of the steel sheet structure.

[0022] The surface of the base 1 is provided with multiple sets of support components 3. The first winding cone 4 and the second winding cone 7 are respectively fitted into the corresponding support components 3 to support the first winding cone 4 and the second winding cone 7, so as to facilitate the subsequent replacement of the first winding cone 4 and the second winding cone 7 for welding processing of different types of steel pipes.

[0023] Support assembly 3 includes a support ring plate 301. Inside the support ring plate 301, clamping plates 304 arranged equidistantly in a circular pattern are slidably connected. The clamping plates 304 penetrate the surface of the support ring plate 301 and are used to compress and fix the first winding cone 4 and the second winding cone 7. Inside the support ring plate 301, a worm gear 302 is rotatably connected. An internal gear ring 303 is fixedly connected to the inner wall of the worm gear 302. Inside the support ring plate 301, gears 307 arranged equidistantly in a circular pattern are rotatably connected. The surface of the gears 307 meshes with the internal gear ring 303. The clamping plates... A rack 305 is fixedly connected to the surface of 304. The rack 305 also slides through the surface of the support ring plate 301 and is slidably connected to the inside of the support ring plate 301. The surface of the rack 305 meshes with the surface of the gear 307. Thus, the rotation of the internal gear ring 303 can synchronously drive all the gears 307 to rotate, thereby driving the rack 305 and the clamping plate 304 to retract inward or move outward, thereby realizing the fixing and loosening of the first winding cone 4 and the second winding cone 7, thus realizing the replacement of the first winding cone 4 and the second winding cone 7.

[0024] The support ring plate 301 is internally rotatably connected to a worm 306 protruding from the surface of the support ring plate 301. The surface of the worm 306 meshes with the surface of the worm wheel 302. Thus, the position of the clamping plate 304 can be locked by the arrangement of the worm wheel 302 and the worm 306, preventing the clamping plate 304 from moving arbitrarily and ensuring the stability of the device in fixing the first winding cone 4 and the second winding cone 7. Secondly, a rubber pad is provided at the end of the clamping plate 304 near the first winding cone 4 and the second winding cone 7 to increase the clamping force of the clamping plate 304 on the first winding cone 4 and the second winding cone 7, thereby improving the fixing effect of the device on the first winding cone 4 and the second winding cone 7.

[0025] An adjustment mechanism 6 is provided on the surface of the base 1. Both take-up wheels 5 are located above the adjustment mechanism 6. The adjustment mechanism 6 includes two moving blocks 603. The surfaces of the two moving blocks 603 are slidably connected to the interior of the base 1. The lower ends of the two take-up wheels 5 are rotatably connected to the interior of the two moving blocks 603 respectively. A movable block 607 is slidably connected to the interior of the base 1. A rotating shaft 606 is rotatably connected to the surface of the movable block 607. A sprocket 602 is fixedly connected to the surfaces of the rotating shaft 606 and the two take-up wheels 5. A chain 604 is meshed with the surfaces of the three sprockets 602, so that the rotating shaft 606 and the two take-up wheels 5 can rotate synchronously.

[0026] The base 1 is internally rotatably connected to a bidirectional threaded rod 601 that passes through the surface of the base 1. The bidirectional threaded rod 601 passes through the surfaces of two movable blocks 603 and is internally threaded to the two movable blocks 603. The internal threads of the two movable blocks 603 are respectively matched with the threads at both ends of the bidirectional threaded rod 601, so that when the bidirectional threaded rod 601 rotates, it can drive the two movable blocks 603 to move relative to each other or in opposite directions, thereby realizing the adjustment of the position of the two winding wheels 5. A spring 605 is fixedly connected between the movable block 607 and the interior of the base 1 to reset the movable block 607. The spring 605 is always in a stretched state.

[0027] Working principle: The steel coil to be welded is installed on the uncoiler body 2, and the uncoiler body 2 uncoils the steel coil. Then, the starting end of the steel sheet is inserted between two rollers (not marked in the figure) and the steel sheet is guided into the take-up cone 4. The take-up cone 4 performs preliminary shaping on the steel sheet, bending it into a semi-circular structure. Then, the steel sheet is sequentially guided into two take-up rollers 5 and the take-up cone 7, so that the steel sheet is bent into a circular tubular structure. Then, the butt joints on the left and right sides of the steel sheet are located in the welding seam. Finally, the butt joints are welded by the welding assembly.

[0028] When different diameter steel pipes need to be formed, i.e., when the winding cone 1 4 and winding cone 2 7 need to be replaced, the operator can rotate the worm gear 306 to drive the worm wheel 302 and the internal gear ring 303 to rotate. Since the internal gear ring 303 meshes with the gear 307, it drives the gear 307 to rotate synchronously. At the same time, since the gear 307 meshes with the rack 305, it drives the rack 305 and the clamping plate 304 to expand outward together, so that the clamping plate 304 no longer clamps and fixes the winding cone 1 4 and winding cone 2 7. At this time, the winding cone 1 4 and winding cone 2 7 can be pulled out to replace the winding cone 1 4 and winding cone 2 7. After the winding cone 1 4 and winding cone 2 7 have been replaced, the worm gear 306 is rotated in the opposite direction to replace the winding cone 1 4 and winding cone 2 7. This allows the device to shape steel pipes of different sizes.

[0029] Secondly, after the first winding cone 4 and the second winding cone 7 are installed, the operator can rotate the double-threaded rod 601 to drive the two moving blocks 603 to move relative to or away from each other in the base 1, thereby changing the position of the two winding wheels 5. As the two moving blocks 603 move, the position of the sprockets 602 on the two winding wheels 5 changes. At this time, under the elastic force of the spring 605, the movable block 607 is driven to slide in the base 1, which in turn drives the position of the sprocket 602 on the rotating shaft 606 to change accordingly, so that the chain 604 is always in a taut state, ensuring that the two winding wheels 5 can rotate synchronously. The movement of the two winding wheels 5 allows the winding wheels 5 to shape the steel sheet into different diameters.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
