Description

Technical Field

[0001] This utility model relates to the field of bolt production technology, and in particular to a cutting device for bolt production. Background Technology

[0002] High-strength bolts are core connecting components in fields such as engineering machinery, bridge construction, and wind power equipment. Their production process has extremely high requirements for blank precision, surface quality, and production continuity. Cutting equipment, as a key piece of equipment in the front-end of high-strength bolt production, is mainly responsible for processing high-strength alloy round steel or wire rod into fixed-length blanks, providing qualified raw materials for subsequent cold heading, heat treatment, and other processes.

[0003] Existing cutting equipment for high-strength bolt production typically uses a heavy-duty workbench as its base. The top of the workbench is equipped with a raw material conveying mechanism and a cutting execution mechanism. The raw material conveying mechanism usually uses two sets of parallel fixed conveying rollers. The conveying rollers are driven by a motor to rotate synchronously, thereby moving the high-strength bolt raw material toward the cutting execution mechanism. The cutting execution mechanism mainly consists of a hydraulically driven cutting frame and a high-speed rotating circular saw blade. The cutting frame can move along the longitudinal guide rail of the workbench. When the raw material is conveyed to the set position, the cutting frame descends, and the saw blade rotates at high speed to cut the raw material.

[0004] However, existing cutting equipment for high-strength bolt production has significant defects in the raw material conveying process. Since high-strength bolt raw materials are mostly high-strength alloy materials, they are prone to slight bending due to stress release during rolling or storage. At the same time, the conveying rollers are fixed installation structures, and their spacing cannot be adjusted according to the actual bending degree or slight diameter deviation of the raw materials. When the bent high-strength bolt raw materials enter between the conveying rollers, the bent parts of the raw materials are prone to friction with the edges of the conveying rollers, resulting in uneven material conveying speed. This poor conveying or jamming phenomenon not only causes scratches on the surface of the raw materials, affecting the quality of the blanks in the subsequent cold heading process, but also forces the production line to stop. Therefore, a cutting equipment for bolt production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a cutting device for bolt production, which aims to improve the problem of poor conveying of bolt raw materials in the prior art due to their own bending or uneven conveying track.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A bolt cutting device includes a workbench, a guide assembly on the top of the workbench, a cutting machine on the top of the workbench, and an adjustment assembly at the bottom of the cutting machine. The guiding assembly includes a guide wheel, the outer wall of which is disposed on the top of the workbench. A bracket is fixedly connected to the top of the workbench, and a sliding rod is slidably connected to the inner wall of the bracket. A slot is formed inside the sliding rod. The outer wall of the guide wheel is rotatably connected to the inner wall of the sliding rod. A locking block is slidably connected to the inner wall of the bracket, and the outer wall of the locking block is slidably connected to the inner wall of the slot. A connecting rod is fixedly connected to the top of the locking block, and the outer wall of the connecting rod is slidably connected to the inner wall of the bracket. A pulling block is fixedly connected to the top of the connecting rod, and a spring is sleeved on the outer wall of the connecting rod. One end of the spring is fixedly connected to the top of the locking block, and the other end of the spring is fixedly connected to the inner wall of the bracket.

[0007] As a further description of the above technical solution: The adjustment component includes a sliding block, the top of which is fixedly connected to the bottom of the cutting machine.

[0008] As a further description of the above technical solution: The workbench has a sliding groove inside and a fixing groove inside.

[0009] As a further description of the above technical solution: The outer wall of the sliding block is slidably connected to the inner wall of the sliding groove, and the sliding block has a sliding groove inside.

[0010] As a further description of the above technical solution: The inner wall of the sliding block is slidably connected to a fixed block, and the outer wall of the fixed block is slidably connected to the inner wall of the fixed groove.

[0011] As a further description of the above technical solution: A limiting plate is fixedly connected to the outer wall of the fixed block, and the outer wall of the limiting plate is slidably connected to the inner wall of the sliding block.

[0012] As a further description of the above technical solution: A pull rod is fixedly connected to the outer wall of the limiting plate, and the outer wall of the pull rod is slidably connected to the inner wall of the slide groove.

[0013] As a further description of the above technical solution: A second spring is provided inside the sliding block. One end of the second spring is fixedly connected to the inner wall of the sliding block, and the other end of the second spring is fixedly connected to the outer wall of the limiting plate.

[0014] This utility model has the following beneficial effects: In this invention, guide wheels guide the bolt material, and then sliding rods fix the position of the guide wheels on the inner wall of the bracket, thus achieving the effect of guiding the bolt material. This avoids situations where the bolt material is not transported smoothly due to its own bending, uneven conveying track, or other reasons, or even gets stuck in the conveying path. It also prevents friction and collision between the material and other parts of the equipment. As a result, the cutting equipment can operate continuously and stably, reducing downtime caused by equipment failure or material conveying problems and improving production efficiency.

[0015] In this invention, the sliding block slides on the inner wall of the sliding groove, and then moves to the inside of the fixed groove by the fixed block, thereby achieving the effect of adjusting the position of the cutting machine. This avoids the need to disassemble the original tool and replace it with a suitable tool holder or tool seat when processing bolts with different radial specifications or different cutting positions, which is not only cumbersome to operate, but also prone to causing the equipment reference to shift due to the disassembly process. This improves the flexibility of multi-specification production and reduces equipment downtime. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 The present invention provides an embodiment of a bolt production cutting device, including a workbench 1. The workbench 1 provides a stable platform for the installation and movement of various structures, thereby ensuring the overall operational stability of the device. A guide component is provided on the top of the workbench 1, and a cutting machine 2 is provided on the top of the workbench 1. The cutting machine 2 performs cutting operations on the bolt raw material, thereby processing the raw material into a blank that meets the requirements of subsequent bolt processes. An adjustment component is provided at the bottom of the cutting machine 2. The guiding assembly includes a guide wheel 6, which contacts the outer wall of the bolt material, converting the sliding friction during material conveying into rolling friction. This reduces frictional resistance between the material and the equipment, thereby reducing surface wear and ensuring smooth conveying. The outer wall of the guide wheel 6 is mounted on the top of the workbench 1, and a bracket 3 is fixedly connected to the top of the workbench 1. The bracket 3 is used to fix the sliding rod 4 and provide a track for its sliding, achieving stable support for the position adjustment of the sliding rod 4. The inner wall of the bracket 3 is slidably connected to the sliding rod 4, which drives the guide wheel 6 to slide along the inner wall of the bracket 3. Adjusting the distance between the two guide wheels 6 adapts to bolt materials of different diameters, expanding the equipment's material compatibility range. The sliding rod 4 has a slot 5 inside, and the outer wall of the guide wheel 6 is rotatably connected to the inner wall of the sliding rod 4. The guide wheel 6 works with the sliding rod 4 to adjust its position. When the sliding rod 4 is adjusted to the appropriate position, the guide wheel 6 can rotate synchronously with the material conveying, achieving both limiting the material's movement and not hindering its advancement, thus achieving a balance between limiting effect and conveying efficiency. The inner wall of the bracket 3 is slidably connected to the sliding rod 4. A locking block 7 is attached, which, in conjunction with the locking groove 5, fixes the sliding rod 4, thereby locking the position of the sliding rod 4 and preventing the guide wheel 6 from shifting during material conveying. The outer wall of the locking block 7 is slidably connected to the inner wall of the locking groove 5. A connecting rod 8 is fixedly connected to the top of the locking block 7, connecting the locking block 7 and the pulling block 10, enabling the pulling block 10 to control the lifting and lowering of the locking block 7, and allowing the position of the locking block 7 to be adjusted through external operation. The outer wall of the connecting rod 8 is slidably connected to the inner wall of the bracket 3, and a pulling block 10 is fixedly connected to the top of the connecting rod 8. The operator can manually pull the connecting rod 8 to move the locking block 7 synchronously, so as to conveniently control the locking block 7 and the locking slot 5. A spring 9 is sleeved on the outer wall of the connecting rod 8. One end of the spring 9 is fixedly connected to the top of the locking block 7, and the other end of the spring 9 is fixedly connected to the inner wall of the bracket 3. When the operator releases the pulling block 10, the spring 9 generates a downward elastic force through its own elastic deformation, pushing the locking block 7 to automatically embed into the locking slot 5, so as to maintain the locking state of the locking block 7 without continuous force and improve the convenience of operation.

[0020] Reference Figure 4 and Figure 5The adjustment component includes a sliding block 13, which drives the cutting machine 2 to move along the sliding groove 11 of the worktable 1, thereby adjusting the lateral position of the cutting machine 2. The top of the sliding block 13 is fixedly connected to the bottom of the cutting machine 2. The sliding groove 11 is provided inside the worktable 1, serving as the movement track for the sliding block 13 and restricting its movement direction to prevent it from deviating during movement, thus ensuring the accuracy of the cutting machine 2's position adjustment. A fixing groove 12 is provided inside the worktable 1, which cooperates with the fixing block 15 to lock the sliding block 13 in different positions. To accommodate different cutting length requirements, the outer wall of the sliding block 13 is slidably connected to the inner wall of the sliding groove 11. The sliding block 13 moves laterally in conjunction with the sliding groove 11. When the sliding block 13 moves smoothly along the inner wall of the sliding groove 11, it drives the top cutting machine 2 to move synchronously, achieving precise adjustment of the cutting position of the cutting machine 2. The sliding block 13 has a sliding groove 14 inside, which is used to limit the movement direction of the pull rod 17 and prevent the pull rod 17 from tilting when pulled, thus ensuring the stability of the movement of the fixed block 15. The inner wall of the sliding block 13 is slidably connected to the fixed block 15, which is engaged in the fixed groove 11. The sliding block 13 is fixed within the 2-inch groove to fix the position of the cutting machine 2, preventing it from shifting during the cutting process. The outer wall of the fixing block 15 is slidably connected to the inner wall of the fixing groove 12. A limit plate 16 is fixedly connected to the outer wall of the fixing block 15, limiting the sliding distance of the fixing block 15 to prevent it from detaching from the sliding block 13 due to excessive sliding, thus ensuring the stability of the connection between the fixing block 15 and the sliding block 13. The outer wall of the limit plate 16 is slidably connected to the inner wall of the sliding block 13, and a pull rod 17 is fixedly connected to the outer wall of the limit plate 16. The pull rod 17 is pulled by the operator to move the limit plate. The plate 16 and the fixed block 15 move synchronously to separate the fixed block 15 from the fixed groove 12, thereby achieving the effect of easily unlocking the position of the sliding block 13. The outer wall of the pull rod 17 is slidably connected to the inner wall of the slide groove 14. A second spring 18 is provided inside the sliding block 13. One end of the second spring 18 is fixedly connected to the inner wall of the sliding block 13, and the other end of the second spring 18 is fixedly connected to the outer wall of the limiting plate 16. When the operator releases the pull rod 17, the second spring 18 generates a thrust through its own elastic deformation to push the limiting plate 16 to reset, thereby causing the fixed block 15 to automatically lock into the fixed groove 12, achieving the effect of quickly locking the position of the sliding block 13.

[0021] Working principle: First, the guide wheel 6 guides the bolt material to prevent bending and misalignment during cutting. Then, by pulling the pull block 10, the connecting rod 8 slides on the inner wall of the bracket 3. The sliding of the connecting rod 8 then moves the locking block 7. When the locking block 7 moves out of the slot 5, it releases the fixation of the sliding rod 4. Then, by pulling the sliding rod 4, it slides on the inner wall of the bracket 3. When it is adjusted to the appropriate position, the pull block 10 is released. Then, the spring 9 returns and the locking block 7 resets. When the locking block 7 moves into the slot 5, it fixes the sliding rod 4. This achieves the effect of adapting to bolt materials of different widths, avoiding the situation where the bolt material is not transported smoothly due to its own bending, uneven conveying track, etc., or even gets stuck in the conveying path, and causing friction and collision between the material and other parts of the equipment. When cutting bolt materials of different specifications, first pull the pull rod 17 to make it slide on the inner wall of the slide groove 14. Then, the sliding of the pull rod 17 causes the limiting plate 16 to slide on the inner wall of the sliding block 13. Subsequently, the sliding of the limiting plate 16 compresses the spring 18. Then, the sliding of the limiting plate 16 causes the fixing block 15 to move. When the fixing block 15 moves out of the fixing groove 12, the fixing of the sliding block 13 is released. Then, pulling the sliding block 13 drives the cutting machine 2. The sliding block 13 slides along the inner wall of the sliding groove 11. When the desired position is reached, the pull rod 17 is released. Then, the spring 18 returns and drives the limit plate 16 to reset. Subsequently, the reset of the limit plate 16 drives the fixing block 15 to move into the interior of the fixing groove 12, thereby completing the fixing of the sliding block 13. This avoids the need for traditional equipment to disassemble the original tool and replace it with a suitable tool holder or tool seat when processing bolts with different radial specifications or different cutting positions because the tool position is fixed. This is not only cumbersome to operate, but also easy to cause the equipment reference to shift due to the disassembly process.
