Description

Technical Field

[0001] This utility model relates to the field of mechanical protection, and in particular to a blade protection mechanism for a double-belt flying shear machine. Background Technology

[0002] The dual-belt flying shear is a key piece of equipment in the metal processing industry, used to achieve high-speed continuous shearing of metal strips. Its cutting tool system, as the core actuator, faces challenges such as high operational safety risks, significant potential for accidental tool contact, and insufficient stability of the protective structure during high-speed operation. Existing protective mechanisms generally suffer from the following defects, hindering improvements in equipment safety and processing efficiency.

[0003] Traditional cutter protection devices mostly use fixed protective covers, which cannot dynamically adjust the protective position according to process parameters such as strip thickness and shearing speed. When switching between different product specifications, the machine must be stopped and the protective structure manually adjusted, resulting in reduced production efficiency and high risks of manual intervention. For example, when the strip thickness changes, the fixed protective plate may interfere with the strip or lose its protective effect due to being too far from the cutter.

[0004] Based on this, we propose a blade protection mechanism for dual-belt flying shears. Utility Model Content

[0005] To address the technical problem that traditional knife protection devices mostly use fixed protective covers, this utility model provides a knife protection mechanism for a double-belt flying shear machine.

[0006] This utility model is achieved using the following technical solution: a blade protection mechanism for a double-belt flying shear machine, comprising a positioning sleeve, which is composed of two semi-circular frames. The two semi-circular frames are joined together to form a circumferential positioning sleeve, and an ear plate is installed at the connection point of the two semi-circular frames. The ear plate is fixedly installed on the surface of the positioning sleeve, and a threaded rod is threaded through the inner side of the ear plate.

[0007] The outer surface of the positioning sleeve has a sliding groove, and a slider is slidably engaged inside the sliding groove. The slider slides circumferentially around the sliding groove and along the positioning sleeve to adjust its position. The sliding groove is a concave groove, and protruding retaining plates are fixedly extended from the upper and lower ends of the sliding groove. The slider is I-shaped, and a moving groove is formed on the surface of the slider, with retaining plates engaging inside the moving groove. A fixing block is fixedly installed on the outer side of the slider, and a damping adjustment shaft block passes through the outer side of the fixing block. A protective plate is fixedly connected to the outer side of the damping adjustment shaft block.

[0008] As a further optimization of this utility model, the positioning sleeve is composed of two semi-circular frames joined together to form a circumferential structure, and quick assembly and disassembly are achieved through the threaded connection between the ear plate and the threaded rod.

[0009] As a further optimization of this utility model, during installation, the positioning sleeve is fitted onto the outside of the double-belt flying shear cutter shaft and tightened by the threaded rod to fix the positioning sleeve in the designated position of the cutter shaft, providing an installation reference for the subsequent protective structure.

[0010] As a further optimization of this utility model, the sliding groove is a concave groove, and the cooperation between the retaining plate and the moving groove forms a guiding and limiting structure. During the sliding process of the slider, the retaining plate moves along the moving groove, which not only restricts the radial movement of the slider, but also provides a stable guiding path for its circumferential sliding, preventing the protective plate from shifting or falling off during the adjustment process, and ensuring the reliability and safety of the entire protective mechanism.

[0011] As a further optimization of this utility model, the damping adjustment shaft block passes through the fixed block and is fixedly connected to the protective plate, providing rotational resistance through the internal damping structure. Simultaneously, the damping force can be adjusted through the external structure of the shaft block to adapt to the protection requirements under different working conditions.

[0012] As a further optimization of this utility model, the slider is I-shaped, and its moving groove is engaged with the locking plates at the upper and lower ends of the sliding groove, so that the slider can slide circumferentially along the sliding groove on the outer surface of the positioning sleeve.

[0013] As a further optimization of this utility model, when it is necessary to adjust the position of the protective plate, the fixed block is pushed to drive the slider to rotate along the sliding groove. According to the requirements of the strip shearing process, the protective plate is adjusted to a suitable position in the circumferential direction of the tool axis to achieve precise matching of the dynamic protection range.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a circumferential sliding structure of positioning sleeve and slider, which allows the protective plate to be dynamically adjusted in position along the circumferential direction of the tool axis, accurately matching the shearing requirements of strips of different thicknesses, and significantly improving the equipment's adaptability to processing products of multiple specifications and production efficiency.

[0016] 2. This utility model provides rotational resistance through the internal damping structure of the damping adjustment shaft block, ensuring that the protective plate remains in a fixed position when the tool is running at high speed, preventing displacement due to vibration or external impact. At the same time, the damping force can be adjusted externally to adapt to different working conditions, taking into account both adjustment flexibility and protection stability, and reducing safety risks.

[0017] 3. This utility model forms a stable guiding and limiting path by cooperating the concave groove of the sliding groove with the I-shaped moving groove of the slider. This restricts the radial movement of the slider while guiding its circumferential sliding, preventing the protective plate from shifting or falling off during adjustment. This ensures the structural reliability of the protective mechanism during dynamic adjustment and provides more stringent safety protection for operators.

[0018] 4. This utility model adopts a double semi-circular frame combination structure through the positioning sleeve, and the ear plate and threaded rod can be quickly disassembled and assembled, so that the installation and maintenance of the protective mechanism can be completed without disassembling the entire tool system.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example 1:

[0026] Please combine Figures 1-3 This embodiment proposes a blade protection mechanism for a double-belt flying shear machine, including a positioning sleeve 1. The positioning sleeve 1 is composed of two semi-circular frames, which are joined together to form a circumferential positioning sleeve 1. An ear plate 2 is installed at the connection point of the two semi-circular frames. The ear plate 2 is fixedly installed on the surface of the positioning sleeve 1, and a threaded rod 3 is threadedly connected to the inner side of the ear plate 2.

[0027] The positioning sleeve 1 consists of two semi-circular frames joined together to form a circumferential structure. It is quickly assembled and disassembled through the threaded connection between the ear plate 2 and the threaded rod 3. During installation, the positioning sleeve 1 is fitted onto the outside of the double-belt flying shear cutter shaft and tightened by the threaded rod 3 to fix the positioning sleeve 1 in the designated position on the cutter shaft, providing an installation reference for the subsequent protective structure.

[0028] The outer surface of the positioning sleeve 1 is provided with a sliding groove 4, and a slider 5 is slidably engaged on the inner side of the sliding groove 4. The slider 5 slides around the sliding groove 4 along the positioning sleeve 1 in a circular motion to achieve position adjustment.

[0029] The sliding groove 4 is a concave groove, and protruding retaining plates 41 are fixedly extended from the upper and lower ends of the sliding groove 4. The slider 5 is I-shaped, and a moving groove 51 is formed on the surface of the slider 5. The surface of the moving groove 51 is provided with rubber protrusions to increase the friction between it and the retaining plate 41 and prevent displacement. The retaining plate 41 is engaged inside the moving groove 51.

[0030] Specifically, the sliding groove 4 is a concave groove, and the cooperation between the retaining plate 41 and the moving groove 51 forms a guide and limiting structure. During the sliding process of the slider 5, the retaining plate 41 moves along the moving groove 51, which not only restricts the radial movement of the slider 5, but also provides a stable guide path for its circumferential sliding, preventing the protective plate 8 from shifting or falling off during the adjustment process, and ensuring the reliability and safety of the entire protective mechanism.

[0031] A fixing block 6 is fixedly mounted on the outer side of the slider 5. A damping adjustment shaft block 7 passes through the outer side of the fixing block 6, and a protective plate 8 is fixedly connected to the outer side of the damping adjustment shaft block 7. The damping adjustment shaft block 7 passes through the fixing block 6 and is fixedly connected to the protective plate 8, providing rotational resistance through an internal damping structure. At the same time, the damping force can be adjusted through the external structure of the shaft block to adapt to the protection requirements under different working conditions.

[0032] More specifically, the slider 5 is I-shaped, and its moving groove 51 engages with the locking plates 41 at the upper and lower ends of the sliding groove 4, allowing the slider 5 to slide circumferentially along the sliding groove 4 on the outer surface of the positioning sleeve 1. When the position of the protective plate 8 needs to be adjusted, the fixed block 6 is pushed to drive the slider 5 to rotate along the sliding groove 4. According to the requirements of the strip shearing process, the protective plate 8 is adjusted to a suitable position in the circumferential direction of the tool axis, achieving precise matching of the dynamic protection range.

[0033] Working principle of the blade protection mechanism for double-belt flying shears

[0034] I. Overall Installation and Positioning Principles

[0035] The positioning sleeve 1 consists of two semi-circular frames joined together to form a circumferential structure. It is quickly assembled and disassembled through the threaded connection between the ear plate 2 and the threaded rod 3. During installation, the positioning sleeve 1 is fitted onto the outside of the double-belt flying shear cutter shaft and tightened by the threaded rod 3 to fix the positioning sleeve 1 in the designated position on the cutter shaft, providing an installation reference for the subsequent protective structure.

[0036] II. Principle of Circumferential Adjustment of Protective Plate 8

[0037] The slider 5 is I-shaped, and its moving groove 51 engages with the locking plates 41 at the upper and lower ends of the sliding groove 4, allowing the slider 5 to slide circumferentially along the sliding groove 4 on the outer surface of the positioning sleeve 1. When it is necessary to adjust the position of the protective plate 8, the fixed block 6 is pushed to drive the slider 5 to rotate along the sliding groove 4. According to the requirements of the strip shearing process, the protective plate 8 is adjusted to a suitable position in the circumferential direction of the tool axis, achieving precise matching of the dynamic protection range.

[0038] III. Damping Adjustment and Stability Principle

[0039] The damping adjustment shaft block 7 passes through the fixed block 6 and is fixedly connected to the protective plate 8, providing rotational resistance through its internal damping structure. Simultaneously, the damping force can be adjusted via the external structure of the shaft block to adapt to protection requirements under different working conditions.

[0040] IV. Guiding and Limiting Principles of Snap-fit ​​Structures

[0041] The sliding groove 4 is a concave groove, and the cooperation between the retaining plate 41 and the moving groove 51 forms a guide and limiting structure. During the sliding of the slider 5, the retaining plate 41 moves along the moving groove 51, which not only restricts the radial movement of the slider 5, but also provides a stable guide path for its circumferential sliding, preventing the protective plate 8 from shifting or falling off during the adjustment process, and ensuring the reliability and safety of the entire protective mechanism.
