[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The shearing device for angle iron processing disclosed in this invention is mainly used in scenarios where existing angle iron shearing equipment is used in operation, but the small cutting end face of the scrap material and the concentrated shearing impact force cause uneven force on the material head, resulting in rapid ejection and easily causing safety accidents such as personnel injury and equipment damage.

[0020] Reference Figures 1-5 A shearing device for processing angle iron, comprising: Base 1, with shearing machine body 3 mounted on its upper side; The anti-ejection assembly 2 is located on one side of the shearing machine body 3. The anti-ejection assembly 2 includes a setting frame 201 and two fixed ratchet plates 211, which are arranged opposite to each other on the outer wall of the setting frame 201. Anti-warping component 4 is located on the other side of the shearing machine body 3. Anti-warping component 4 includes an upper fixing plate 401.

[0021] In this invention, the anti-material ejection assembly 2 further includes: The buffer bag 205 is located on the side of the setting frame 201 away from the shearing machine body 3. Multiple soft magnetic rings 206 of different sizes are evenly spaced on the outer wall of the buffer bag 205.

[0022] In this invention, the anti-material ejection assembly 2 further includes: The tube frame 208 is disposed on the outer wall of the end of the cushioning bag 205 away from the mounting frame 201; Rotating rod 209 is located inside the tube frame 208.

[0023] In this invention, the anti-material ejection assembly 2 further includes: Multiple fixing brackets 204 are disposed on the outer wall of the setting frame 201, and each of the multiple fixing brackets 204 has a retracting shaft 213 disposed inside it. Multiple take-up and take-down wheels 212 are respectively disposed on the outer wall of the corresponding take-up and take-down shaft 213.

[0024] In this invention, the anti-material ejection assembly 2 further includes: Two collars 207 are provided on the outer walls of both ends of the rotating rod 209. The outer walls of the two collars 207 are fixedly connected to the ends of two take-up and release ropes 214. The other ends of the multiple take-up and release ropes 214 are respectively wound around the outer wall of their respective take-up and release wheels 212. Multiple receivers 5 are mounted on corresponding fixed frames 204, and the drive ends of the multiple receivers 5 are connected to one end of the corresponding receiver shaft 213 via couplings.

[0025] In this invention, the anti-material ejection assembly 2 further includes: Two U-shaped plates 203 are disposed opposite to each other on the outer wall of the shearing machine body 3, and two tie rods 217 are slidably connected inside the two U-shaped plates 203 respectively; Two locking ratchet plates 215 are respectively disposed at one end of the corresponding two pull rods 217, and the two locking ratchet plates 215 are respectively engaged with the corresponding fixed ratchet plates 211. Multiple locking springs 216 are respectively sleeved on the outer wall of the corresponding pull rod 217. One end of each locking spring 216 is fixedly connected to the corresponding locking ratchet plate 215, and the other end of each locking spring 216 is fixedly connected to the inner wall of the corresponding U-shaped plate 203. Two pull plates 218 are respectively set at the other end of the two corresponding pull rods 217; Two air-gathering boxes 202 are disposed opposite to each other on the outer wall of the shearing machine body 3, and two connecting holes are respectively opened on one side of the two air-gathering boxes 202.

[0026] In this invention, the anti-material ejection assembly 2 further includes: Multiple blowing pipes 210 are respectively disposed inside the corresponding fixed ratchet plate 211. The air inlet ends of two blowing pipes 210 located inside the same fixed ratchet plate 211 are respectively located inside two connecting holes opened in the same air gathering box 202, and the air outlet ends of the two blowing pipes 210 located inside the same fixed ratchet plate 211 pass through the setting frame 201 and are located inside it. Two air pumps 6 are respectively installed on the corresponding air collection box 202, and the air filling end of the two air pumps 6 is connected to the inside of the corresponding air collection box 202.

[0027] Specifically, during the shearing of small-area scrap of angle iron, the anti-material ejection assembly 2 is first installed onto the shearing machine body 3. Two fixing ratchet plates 211 are aligned with the interior of two U-shaped plates 203 and pushed in until the setting frame 201 is pressed against one side of the shearing machine body 3. At this point, the two locking ratchet plates 215 are firmly engaged with the corresponding fixing ratchet plates 211 under the elastic force of the corresponding locking springs 216, thus fixing the setting frame 201 securely to one side of the shearing machine body 3. Multiple blowing pipes 210 follow the movement of the two fixing ratchet plates 211. The moving parts are inserted into the corresponding connecting holes of the air-gathering boxes 202. Then, by turning on the two air pumps 6, a large amount of air is injected into the two air-gathering boxes 202. The large amount of air then leaves the two air-gathering boxes 202 and enters the buffer area formed by the shearing machine body 3, the setting frame 201, and the buffer bag 205 through multiple blowing pipes 210. The buffer bag 205 expands and stretches under the blowing of a large amount of air, thereby causing the rotating rod 209 to move outward and causing the two collars 207 on it to pull the take-up and release rope 214. During this process, multiple take-up and release motors 5 are turned on to make multiple Each take-up and release shaft 213 drives the corresponding take-up and release wheel 212 to rotate, thereby maintaining the tension of the take-up and release rope 214 while cooperating with the pull rope work of the two collars 207, thus achieving stable expansion and uniform expansion of the cushioning bag 205. When the cushioning bag 205 expands to its maximum value, multiple take-up and release motors 5 are turned off. Through the restriction of multiple take-up and release ropes 214 and the continuous blowing of multiple air pumps 6, the cushioning bag 205 is always kept in an expanded and elongated state, thereby maintaining the cushioning environment. When cutting small-area scraps of angle iron, due to the cutting position of the angle iron... The rear end is squeezed and fixed by the triangular anti-warping plate 402, so that the angle iron will not warp during shearing. Since the shearing end area of ​​this scrap is small, the impact force at the moment of shearing is concentrated and too large, causing the cut scrap to be unevenly stressed and ejected rapidly. The ejected scrap is buffered and blocked by the expanded and elongated buffer bag 205, so that the scrap will not be ejected into the external environment. While the scrap is buffered and blocked by the buffer bag 205, multiple soft magnetic rings 206 further weaken the impact force of the scrap under the action of magnetic force, so that the scrap falls steadily into the interior of the buffer bag 205.

[0028] In specific application scenarios, by aligning the fixed ratchet plate 211 with the U-shaped plate 203 and pushing it in, the locking ratchet plate 215 automatically engages under the elastic force of the locking spring 216, achieving quick and stable installation of the anti-material ejection component 2 and the shearing machine body 3. No additional tools are required, operation is simple, and the connection is reliable. After the air pump 6 inflates the air collection box 202, the air is evenly delivered into the buffer area through the blowing pipe 210, providing a continuous and stable air source for the buffer bag 205, ensuring the smooth start and maintenance of the expansion action. The buffer bag 205 expands and elongates under the blowing of a large amount of air, forming a flexible buffer barrier, effectively intercepting and absorbing the kinetic energy of the sheared material head, preventing the material head from splashing into the external environment. The take-up and discharge motor 5 drives the take-up and discharge shaft 213 and the take-up and discharge wheel 212, equipped with... The pulling of the collar 207 on the take-up and release rope 214 can maintain the tension of the take-up and release rope 214 and guide the bag to stretch evenly, avoiding excessive local expansion and ensuring the shape stability and expansion uniformity of the buffer area. While the buffer bag 205 blocks the material head, the soft magnetic ring 206 uses magnetic force to generate additional damping on the metal material head, further weakening the impact force of the material head and allowing the material head to fall smoothly into the bag, reducing the risk of rebound or penetration. When there is no risk of ejection when shearing large areas of scrap material, pulling the pull plate 218 can disengage the locking ratchet plate 215 from the fixed ratchet plate 211, quickly releasing the lock and facilitating the overall disassembly of the anti-material head ejection assembly 2. At the same time, it is convenient to clean and recycle the material head accumulated in the buffer bag 205, improving the equipment's versatility and maintenance convenience.

[0029] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 In a preferred embodiment, the anti-warping component 4 further includes: The lower fixing plate 404 is located on the other side of the shearing machine body 3, and is located directly below the upper fixing plate 401. Guide groove block 403 is disposed on the upper side of the lower fixing plate 404.

[0030] In this invention, the anti-warping component 4 further includes: An electric telescopic rod 405 is installed on the upper side of the upper fixed plate 401. The telescopic end of the electric telescopic rod 405 is provided with a triangular anti-tilting plate 402. The outer wall of the triangular anti-tilting plate 402 is provided with multiple delivery slots, and two support plates 408 are respectively installed inside the multiple delivery slots.

[0031] In this invention, the anti-warping component 4 further includes: Multiple rotating shafts 406 are connected to the interior of two corresponding support plates 408 via bearings, and delivery wheels 407 are respectively provided on the outer walls of the multiple rotating shafts 406. Multiple delivery motors 409 are respectively mounted on corresponding support plates 408, and the drive ends of the multiple delivery motors 409 are respectively connected to one end of the corresponding rotating shaft 406 via couplings.

[0032] Specifically, after the anti-material ejection assembly 2 is installed and debugged, the shearing end of the angle iron with shearing is placed on the upper side of the guide groove block 403. Then, the triangular anti-tilting plate 402 is lowered by opening the electric telescopic rod 405 until multiple delivery wheels 407 contact the inner side of the angle iron. Then, multiple delivery motors 409 are turned on to drive multiple rotating shafts 406 to rotate the corresponding delivery wheels 407, so that the angle iron is stably conveyed into the shearing machine body 3 for shearing. When shearing small-area scraps of angle iron, the rear end of the angle iron at the shearing position is squeezed and fixed by the triangular anti-tilting plate 402, so that the angle iron will not warp during shearing.

[0033] In specific application scenarios, the guide block 403 provides an accurate placement benchmark for the angle iron, ensuring precise positioning of the shearing end. The electric telescopic rod 405 controls the triangular anti-warping plate 402 to press down, forming a compression fixation at the rear end of the shearing position, effectively preventing warping of the angle iron during shearing, which is especially crucial for shearing small-area scraps. The delivery motor 409 drives the delivery wheel 407 to rotate through the rotating shaft 406, realizing stable and controllable feeding of the angle iron, improving the continuity and safety of shearing.

[0034] Working principle: Before cutting small areas of scrap angle iron during use, the anti-material ejection assembly 2 must be installed on the shearing machine body 3. During this process, first align the two fixing ratchet plates 211 with the two U-shaped plates 203 and push them in until the setting frame 201 is pressed tightly against one side of the shearing machine body 3. At this time, the two locking ratchet plates 215 are firmly engaged with the fixing ratchet plates 211 under the elastic force of the corresponding locking springs 216, thereby achieving stable fixing of the setting frame 201 on one side of the shearing machine body 3. Meanwhile, as the fixed ratchet plate 211 moves, multiple blowing pipes 210 are inserted into the corresponding connecting holes of the air-gathering boxes 202. Then, two air pumps 6 are started to continuously fill the two air-gathering boxes 202 with a large amount of air. The air is divided by the air-gathering boxes 202 and enters the buffer area formed by the shearing machine body 3, the setting frame 201, and the buffer bag 205 through each blowing pipe 210. Under the blowing action of high-pressure air, the buffer bag 205 continuously expands and elongates, driving the rotating rod 209 to move outward, thereby causing the two collars on the rod to... 207 pulls the take-up and release rope 214. During this process, multiple take-up and release motors 5 start simultaneously, driving the take-up and release shaft 213 to rotate the take-up and release wheel 212 to maintain the appropriate tension of the take-up and release rope 214. In conjunction with the rope pulling action of the collar 207, the expansion process of the cushioning bag 205 is ensured to be smooth and uniform. When the cushioning bag 205 expands to its maximum elongation, the take-up and release motors 5 are turned off. The limiting effect of the take-up and release rope 214 and the continuous air supply of the air pump 6 are used to keep the cushioning bag 205 in a fully expanded state, thereby creating a reliable cushioning and protection environment. After the anti-material ejection assembly 2 is installed and debugged, place the shearing end of the angle iron to be sheared on the upper side of the guide groove block 403, start the electric telescopic rod 405 to lower the triangular anti-tilting plate 402 until multiple delivery wheels 407 contact the inside of the angle iron. Then, turn on multiple delivery motors 409 to drive the rotating shaft 406 to rotate the delivery wheels 407, thereby smoothly feeding the angle iron into the shearing machine body 3 for shearing. When shearing small-area scraps, the rear end of the angle iron at the shearing position is pressed and fixed by the triangular anti-warping plate 402, which can effectively prevent the angle iron from warping during the shearing process. At the same time, because the cross-sectional area of ​​the scrap is small, the impact force is concentrated and large at the moment of shearing. The cut-off piece is subjected to uneven force and is prone to be ejected rapidly. At this time, the buffer bag 205, which has been expanded to its maximum state, can effectively block the flying piece and prevent it from being ejected into the external environment. Meanwhile, multiple soft magnetic rings 206 further absorb and weaken the impact kinetic energy of the piece under the action of magnetic force, so that the piece falls smoothly into the buffer bag 205. When cutting large-area angle iron scraps, the scraps are less likely to splatter due to their large size. In this case, the anti-scraping component 2 can be removed to avoid obstructing the cutting operation. To remove it, simply pull the two pull plates 218 to disengage the multiple locking ratchet plates 215 from the corresponding fixed ratchet plates 211. After unlocking, the component can be easily removed from the shearing machine body 3. At the same time, the scraps collected in the buffer bag 205 can also be recycled.
