Description

Technical Field

[0001] This utility model relates to the field of flat steel rolling technology, specifically a clamping mechanism suitable for flat steel rolling. Background Technology

[0002] In the flat steel rolling production process, the clamping mechanism is a key piece of equipment to ensure production continuity and product quality. There is a clamping mechanism located between two conveyor lines. The clamping mechanism is used to clamp and suspend the material, and transport it from the front conveyor line to the rear conveyor line. During the suspended transport process, other existing equipment is used to process it.

[0003] Traditional flat steel clamping mechanisms mostly employ rigid clamping structures. When dealing with flat steel of different sizes and specifications, this often requires frequent manual clamp changes or equipment parameter adjustments, resulting in cumbersome and inefficient operations that fail to meet the demands of modern industrial production for high efficiency and flexibility. Some clamping mechanisms with adjustable structures suffer from complex adjustment methods and insufficient precision, leading to problems such as inaccurate flat steel positioning and unstable clamping during the clamping process. This causes the flat steel to shift and wobble during rolling, affecting not only the dimensional accuracy and surface quality of the product but also potentially causing equipment malfunctions and safety accidents. Furthermore, existing clamping mechanisms often rely on additional unlocking devices to release the flat steel, increasing equipment costs and maintenance complexity. Therefore, we propose a clamping mechanism suitable for flat steel rolling to address these existing problems. Utility Model Content

[0004] The purpose of this invention is to provide a clamping mechanism suitable for flat steel rolling, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping mechanism suitable for flat steel rolling, comprising a base, mounting components, a drive motor, a mounting seat, and a clamping mechanism. Mounting components are fixedly connected to both sides of the base, and slide rails are symmetrically arranged on the base. A mounting seat is fixedly connected to the center of the base. A bidirectional lead screw is movably connected to the mounting component on the mounting seat. A drive motor is fixedly connected to one side of the mounting component, and a bidirectional lead screw is fixedly connected to the output end of the drive motor. Sliding seats are symmetrically slidably connected to the slide rails, and each sliding seat is provided with a clamping mechanism.

[0006] Preferably, the clamping mechanism includes a clamping frame, a top plate, a clamping plate, a rotating frame, a limiting plate, a reset groove, a rotating rod, a reset spring, and a guide rail. Each sliding seat is fixedly connected to a clamping frame, and guide rails are symmetrically arranged inside the clamping frame. A top plate is slidably connected to the guide rails. Rotating frames are fixedly connected to both the upper and lower sides of the top plate. Each rotating frame is movably connected to a clamping plate. The clamping plate has an L-shaped structure, and a rotating rod is movably connected to the middle of the clamping plate. The clamping plate is movably connected to a clamping plate through the rotating rod.

[0007] Preferably, a reset groove is provided on the side of the top plate near the sliding seat, a reset spring is provided in the reset groove, a mounting base is fixedly connected to the side of the reset spring away from the reset groove, and a limit plate is fixedly connected to the side of the top plate away from the sliding seat.

[0008] Preferably, the sliding seat has a through hole below the clamping frame, and a placement seat is fixedly connected to the upper side of the mounting seat, with the placement seat and the through hole matching each other in size.

[0009] Preferably, a flat steel bar is placed on the placement seat, and the flat steel bar cooperates with the limiting plate and the clamping plate.

[0010] Preferably, the lower part of the sliding seat has a threaded structure, and the threads of the sliding seat and the bidirectional lead screw are mutually engaged.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The drive motor starts and drives the double-acting screw to rotate. Because the sliding seat has a threaded structure and is threaded with the double-acting screw, the two sliding seats will move closer to each other on the slide rail. As the sliding seats move, the clamping frame fixed on the sliding seats will also move to accommodate flat steel of different sizes.

[0013] 2. During the movement of the clamping frame, the top plate contacts the flat steel and slides on the guide rail. When the top plate moves, it drives the rotating frame to move, which in turn causes the clamping plate to rotate around the rotating rod, gradually approaching the flat steel and finally clamping it. During this process, the limiting plate restricts the position of the flat steel in the horizontal direction, ensuring that the flat steel is accurately clamped. During the clamping process, the return spring is compressed. The function of the return spring is to provide a reverse elastic force. When it is necessary to release the flat steel, the drive motor reverses, the bidirectional lead screw rotates in the opposite direction, and the sliding seat moves relatively away. At this time, under the elastic force of the return spring, the top plate will slide away from the sliding seat on the guide rail, causing the clamping plate to rotate around the rotating rod, so that the clamping plate releases the flat steel and returns to the initial open state.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] like Figures 1-4 As shown, the present invention proposes a clamping mechanism suitable for flat steel rolling, comprising a base 1, mounting parts 2, a drive motor 3, a mounting seat 4, and a clamping mechanism 8. Mounting parts 2 are fixedly connected to both sides of the base 1, and slide rails 10 are symmetrically arranged on the base 1. The mounting seat 4 is fixedly connected to the middle of the base 1. A bidirectional lead screw 5 is movably connected to the mounting parts 2 on the mounting seat 4. A drive motor 3 is fixedly connected to one side of the mounting parts 2, and the output end of the drive motor 3 is fixedly connected to the bidirectional lead screw 5. Sliding seats 7 are symmetrically slidably connected to the slide rails 10, and each sliding seat 7 is provided with a clamping mechanism 8.

[0021] In an optional embodiment, the clamping mechanism 8 includes a clamping frame 801, a top plate 802, a clamping plate 803, a rotating frame 804, a limiting plate 805, a reset groove 806, a rotating rod 807, a reset spring 808, and a guide rail 809. The clamping frame 801 is fixedly connected to each of the sliding seats 7. The guide rail 809 is symmetrically arranged inside the clamping frame 801. The top plate 802 is slidably connected to the guide rail 809. The rotating frame 804 is fixedly connected to both the upper and lower sides of the top plate 802. The clamping plate 803 is movably connected to each of the rotating frames 804. The clamping plate 803 has an L-shaped structure, and the rotating rod 807 is movably connected to the middle of the clamping plate 803. The clamping plate 803 is movably connected to the rotating rod 807.

[0022] In an optional embodiment, a reset groove 806 is provided on the side of the top plate 802 near the sliding seat 7, a reset spring 808 is provided in the reset groove 806, a mounting base 4 is fixedly connected to the side of the reset spring 808 away from the reset groove 806, and a limit plate 805 is fixedly connected to the side of the top plate 802 away from the sliding seat 7.

[0023] In an optional embodiment, the sliding seat 7 has a through hole 9 below the clamping frame 801, and a placement seat 6 is fixedly connected to the upper side of the mounting seat 4, with the placement seat 6 and the through hole 9 matching each other in size.

[0024] In an optional embodiment, a flat steel bar is placed on the placement seat 6, and the flat steel bar cooperates with the limiting plate 805 and the clamping plate 803.

[0025] During the movement of the clamping frame 801, the top plate 802 contacts the flat steel and slides on the guide rail 809. When the top plate 802 moves, it drives the rotating frame 804 to move, which in turn causes the clamping plate 803 to rotate around the rotating rod 807, gradually approaching the flat steel and finally clamping it. During this process, the limiting plate 805 restricts the position of the flat steel in the horizontal direction, ensuring that the flat steel is accurately clamped. During the clamping process, the return spring 808 is compressed. The function of the return spring 808 is to provide a reverse elastic force. When it is necessary to release the flat steel, the drive motor 3 reverses, the double-acting screw 5 rotates in the opposite direction, and the sliding seat 7 moves relatively away. At this time, under the elastic force of the return spring 808, the top plate 802 will slide away from the sliding seat 7 on the guide rail 809, causing the clamping plate 803 to rotate around the rotating rod 807, so that the clamping plate 803 releases the flat steel and returns to the initial open state.

[0026] In an optional embodiment, the lower part of the sliding seat 7 has a threaded structure, and the sliding seat 7 and the bidirectional lead screw are threadedly engaged.

[0027] The drive motor 3 starts, causing the bidirectional lead screw 5 to rotate. Since the sliding seat 7 has a threaded structure at the bottom and is threadedly engaged with the bidirectional lead screw 5, the two sliding seats 7 will move relatively close to each other on the slide rail 10. As the sliding seats 7 move, the clamping frame 801 fixed on the sliding seats 7 will also move accordingly.

[0028] The working principle of this utility model is as follows: Before starting work, the reset spring 808 is in a certain initial state, so that the top plate 802 is in a relatively stable position on the guide rail 809. At this time, the clamping plate 803 is also in a relatively open position so as to accommodate the flat steel to be clamped and placed on the placement seat 6. The flat steel is placed on the placement seat 6, and the size of the through hole 9 under the sliding seat 7 matches each other to ensure the stability of the flat steel placement. At this time, the position of the flat steel corresponds to the limiting plate 805 and the clamping plate 803, which prepares for the subsequent clamping operation. The drive motor 3 starts and drives the bidirectional lead screw 5 to rotate. Since the sliding seat 7 has a threaded structure and is threaded with the bidirectional lead screw 5, the two sliding seats 7 will move relatively close on the slide rail 10. As the sliding seats 7 move, the clamping frame 801 fixed on the sliding seats 7 will also move accordingly.

[0029] During the movement of the clamping frame 801, the top plate 802 contacts the flat steel and slides on the guide rail 809. When the top plate 802 moves, it drives the rotating frame 804 to move, which in turn causes the clamping plate 803 to rotate around the rotating rod 807, gradually approaching the flat steel and finally clamping it. During this process, the limiting plate 805 restricts the position of the flat steel in the horizontal direction, ensuring that the flat steel is accurately clamped. During the clamping process, the return spring 808 is compressed. The function of the return spring 808 is to provide a reverse elastic force. When it is necessary to release the flat steel, the drive motor 3 reverses, the double-acting screw 5 rotates in the opposite direction, and the sliding seat 7 moves relatively away. At this time, under the elastic force of the return spring 808, the top plate 802 will slide away from the sliding seat 7 on the guide rail 809, causing the clamping plate 803 to rotate around the rotating rod 807, so that the clamping plate 803 releases the flat steel and returns to the initial open state.

[0030] It should be understood that the specific embodiments described above are for illustrative purposes or to explain the principles of this utility model, and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
