Technical Field

[0001] This utility model relates to the technical field of steel coil processing equipment, and in particular to a clamping device for steel coil processing. Background Technology

[0002] Steel coils are coiled steel products made from steel plates through hot or cold rolling processes. They are characterized by high strength, corrosion resistance, and ease of processing, and are mainly used in construction, automobiles, shipbuilding, and home appliances. Types include hot-rolled coils, cold-rolled coils, galvanized coils, and stainless steel coils, which can be processed into steel plates, pipes, and machine parts. Transporting steel coils in bulk reduces logistics costs and is suitable for large-scale industrial production needs.

[0003] Research indicates that traditional steel coil fixing often involves manual binding with wire ropes or wooden strips, requiring multiple people and demanding high levels of operator experience, resulting in low loading and unloading efficiency and high labor costs. Therefore, a clamping device for steel coil processing is provided to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping device for steel coil processing, which has the advantages of high steel coil clamping efficiency and convenient and quick loading and unloading, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping device for steel coil processing, comprising: a support frame, a drive motor fixedly connected above the support frame, and a steel coil locking mechanism fixedly connected to the rotating shaft of the drive motor;

[0006] The steel coil locking mechanism includes an electric telescopic rod, a cross-shaped fixing frame fixedly connected to the side of the electric telescopic rod, a limit groove formed on the side of the cross-shaped fixing frame, a central moving cylinder fixedly connected to the movable end of the electric telescopic rod, a rotating support arm rotatably connected to the outer side of the central moving cylinder, an inner support plate of the steel coil rotatably connected to the other end of the rotating support arm, a limit slider fixedly connected to the side of the inner support plate near the cross-shaped fixing frame, a spring groove formed on the side of the inner support plate, a support spring fixedly connected to one end of the inner wall of the spring groove, and a trapezoidal locking block fixedly connected to the other end of the support spring.

[0007] As a further improvement of this utility model, the limiting slide groove is provided in four sets, which are equidistantly arranged in a ring on the outside of the cross fixing frame.

[0008] As a further improvement of this utility model, the inner side of the inner support plate of the steel coil is provided with a rotating groove for rotating the support arm.

[0009] As a further improvement of this utility model: the number of rotating support arms is set in four groups, arranged in a circular array on the outside of the middle moving cylinder, and each group has two rotating support arms, and each group of rotating support arms is rotatably connected to the inner support plate of the same group of steel coils.

[0010] As a further improvement of this utility model: the limiting slider is adapted to the limiting groove, and the inner support plate of the steel coil is slidably connected to the cross fixing frame through the limiting slider.

[0011] As a further embodiment of this utility model: when the support spring is naturally extended without being subjected to external force, the trapezoidal locking block is partially located inside the spring groove, and only the inclined part of the trapezoidal locking block extends out of the spring groove. When the support spring is compressed, the trapezoidal locking block can be completely retracted into the spring groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the axial displacement of the moving cylinder is controlled by an electric telescopic rod, which can precisely adjust the radial expansion range of the four sets of inner support plates of the steel coil, thereby adapting to steel coils with different inner diameters.

The embodiments of this utility model will be described below based on its overall structure.

[0021] Reference Figures 1 to 4 In this embodiment of the present invention, a clamping device for processing steel coils includes: a support frame 1, a drive motor 2 fixedly connected above the support frame 1, and a steel coil locking mechanism 3 fixedly connected to the rotating shaft of the drive motor 2.

[0022] The above scheme employs a support frame 1 that provides rigid support for the entire device. The drive motor 2, through its rotating shaft, drives the steel coil locking mechanism 3 to rotate, thereby driving the fixed steel coil to rotate synchronously with the steel coil locking mechanism 3, thus achieving power transmission during the processing. The steel coil locking mechanism 3, through the cooperation of its internal telescopic and locking structures, completes the fixing and releasing of the inner wall of the steel coil.

[0023] The steel coil locking mechanism 3 includes an electric telescopic rod 31. A cross-shaped fixing frame 32 is fixedly connected to the side of the electric telescopic rod 31. Limiting grooves 33 are provided on the side of the cross-shaped fixing frame 32. Four sets of limiting grooves 33 are provided, arranged in a ring at equal intervals outside the cross-shaped fixing frame 32. A central moving cylinder 34 is fixedly connected to the movable end of the electric telescopic rod 31. A rotating support arm 35 is rotatably connected to the outer side of the central moving cylinder 34. The other end of the rotating support arm 35 is rotatably connected to a steel coil inner support plate 36. A rotating groove for rotating the rotating support arm 35 is provided on the inner side of the steel coil inner support plate 36. Four sets of rotating support arms 35 are arranged in a ring array outside the central moving cylinder 34. Each set contains two rotating support arms 35. Each set of rotating support arms 35 is rotatably connected to the same set of steel coil inner support plates 36. The steel coil inner support plate 36 is close to... A limiting slider 37 is fixedly connected to one side of the cross-shaped fixing bracket 32. The limiting slider 37 is adapted to the limiting groove 33. The inner support plate 36 of the steel coil is slidably connected to the cross-shaped fixing bracket 32 ​​through the limiting slider 37. A spring groove 38 is opened on the side of the inner support plate 36 of the steel coil. One end of the support spring 39 is fixedly connected to the inner wall of the spring groove 38. The other end of the support spring 39 is fixedly connected to the trapezoidal locking block 310. When the support spring 39 is not subjected to external force and naturally extends, part of the trapezoidal locking block 310 is located inside the spring groove 38. Only the inclined part of the trapezoidal locking block 310 extends out of the spring groove 38. When the support spring 39 is compressed, the trapezoidal locking block 310 can be completely retracted into the spring groove 38. The trapezoidal locking block 310 allows four sets of inner support plates 36 of the steel coil to be inserted into the inner side of the steel coil while automatically popping out to prevent the steel coil from axial displacement and falling out when rotating.

[0024] Using the above scheme: When the electric telescopic rod 31 pushes the moving cylinder 34 axially, the lever action of the rotating support arm 35 drives the four sets of inner support plates 36 of the steel coil to slide radially along the limiting groove 33 of the cross fixing frame 32, realizing the expansion or contraction of the inner support plates 36 of the steel coil. When the inner support plate 36 of the steel coil is inserted into the inner hole of the steel coil, the inclined surface of the trapezoidal locking block 310 is squeezed by the inner wall of the steel coil, causing the support spring 39 to be compressed. At this time, the trapezoidal locking block 310 is completely retracted into the spring groove 38. When the inner support plate 36 of the steel coil is completely inserted into the steel coil, the support spring 39 resets and pushes the trapezoidal locking block 310 to partially extend out of the spring groove 38. Its vertical surface forms an axial limit with the outer end of the steel coil to prevent the steel coil from coming out during processing. At this time, the inner support plate 36 of the steel coil can be appropriately expanded to make the steel coil and the steel coil locking mechanism 3 tightly connected. After that, when the drive motor 2 drives the entire steel coil locking mechanism 3 to rotate, the inner support plate 36 of the steel coil is allowed to rotate synchronously with the steel coil to avoid structural interference.

[0025] The working principle of this utility model is as follows: The steel coil is placed on the outside of the steel coil locking mechanism 3. At this time, the electric telescopic rod 31 is in a retracted state, the central moving cylinder 34 drives the rotating support arm 35 to retract, and the four sets of inner support plates 36 of the steel coil are in a radially retracted state, which facilitates the insertion of the inner hole of the steel coil. When the inner support plate 36 of the steel coil is inserted into the inner hole of the steel coil, the inclined surface of the trapezoidal locking block 310 on its side is squeezed by the inner wall of the steel coil, and the support spring 39 is compressed, so that the trapezoidal locking block 310 is completely retracted into the spring groove 38, so as to avoid obstructing the insertion of the steel coil. When the inner support plate 36 of the steel coil is fully inserted into the steel coil, the trapezoidal locking block 310 loses the squeeze of the inner wall of the steel coil, the support spring 39 returns to its original position and pushes the trapezoidal locking block 310 partially out of the spring groove 38. Its vertical surface forms an axial limit with the outer end of the steel coil to prevent the steel coil from axially coming out during processing.

[0026] The electric telescopic rod 31 is activated to push the central moving cylinder 34 to move axially. Through the lever action of the two sets of rotating support arms 35, the four sets of inner support plates 36 of the steel coil are driven to expand radially and synchronously outward along the limiting slide groove 33 of the cross fixing frame 32 until the outer wall of the inner support plate 36 of the steel coil is tightly attached to the inner wall of the steel coil.

[0027] After the drive motor 2 starts, it drives the steel coil locking mechanism 3 to rotate as a whole through the rotating shaft. The inner support plate 36 of the steel coil maintains radial stability through the sliding cooperation between the limiting slider 37 and the limiting groove 33. The axial limiting function of the trapezoidal locking block 310 can counteract the axial displacement trend of the steel coil during processing and ensure clamping reliability.

[0028] After processing, the electric telescopic rod 31 retracts in the opposite direction, causing the inner support plate 36 of the steel coil to retract radially inward, pressing the trapezoidal locking block 310 into the inner side of the spring groove 38 so that it retracts completely into the spring groove 38. At this time, the steel coil can easily disengage from the steel coil locking mechanism 3 along the axial direction.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
