Description

Technical Field

[0001] This invention belongs to the field of steel ingot end cutting technology, specifically a cylindrical steel ingot end cutting device. Background Technology

[0002] After the columnar steel ingot is cast, casting defects such as shrinkage cavities, porosity, and unevenness are prone to occur at both ends of the ingot. In order to ensure that the end face quality meets the inspection requirements, the two ends of the steel ingot need to be precisely cut by sawing or flame cutting to obtain a flat and smooth end face, thereby ensuring the accuracy and reliability of the test data. Since sawing has advantages over flame cutting, such as high precision, smooth end face, and no heat-affected zone, sawing is generally used for cutting columnar steel ingots.

[0003] Patent CN217832114U discloses a cylindrical steel ingot end-cutting device, including a base, an electric turntable, a platform, rollers, upper and lower clamping blocks, a cutting box, and a cutting saw. The working principle is as follows: the steel ingot is placed on the rollers, and a hydraulic cylinder drives a push plate to rise. The lower clamping blocks, arranged in a staggered pattern, lift the ingot and clamp it securely with the upper clamping blocks. The electric turntable rotates the platform 180° to flip the ingot, allowing the cutting saw in the cutting box to complete the end-cutting operation. This compact device, through the coordinated actions of roller conveying, clamping, and turntable flipping, achieves efficient positioning, stable clamping, and double-sided cutting of the steel ingot, improving the automation level and ease of operation in the cutting process.

[0004] In the above-mentioned scheme, after one end of the cylindrical steel ingot is cut, multiple processes need to be completed in sequence, such as the pusher plate descending, the steel ingot being removed, clamping, the platform rotating 180°, the pusher plate descending again, being fed in again, and being clamped again, before the other end of the cylindrical steel ingot can be cut. The non-cutting auxiliary time is too long, which reduces the cutting efficiency of the cylindrical steel ingot. Secondly, after the cylindrical steel ingot is processed, it is necessary to remove the processed cylindrical steel ingot before the next set of steel ingots can be processed, which seriously affects the cycle time of steel ingot processing and further reduces the cutting efficiency of steel ingot. Therefore, the present invention provides a cylindrical steel ingot end cutting device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A cylindrical steel ingot end cutting device of this invention includes a cutting box, a first conveying mechanism arranged behind the cutting box, a second conveying mechanism and a third conveying mechanism arranged sequentially in front of the cutting box, a discharge port opened on one side of the lower end of the cutting box, a feeding box placed below the discharge port, an inclined plate fixedly installed inside the discharge port, a cutting mechanism installed on the cutting box, and conveying holes opened on both the front and rear sides of the cutting box. A fixing mechanism for clamping the steel ingot is arranged inside the conveying holes. The cutting mechanism includes a lifting plate movably inserted into the cutting box. On the cutting box, a hydraulic cylinder is fixedly installed to drive the lifting plate, a cutting blade is rotated and installed at the lower end of the lifting plate, two sets of synchronous gears are rotated and installed on the lifting plate, both sets of synchronous gears mesh with a synchronous belt, a motor is fixedly installed at the upper end of the lifting plate to drive one set of synchronous gears, the cutting end is connected to another set of synchronous gears, the fixing mechanism includes two sets of clamping plates, the two sets of clamping plates are symmetrically distributed on both sides of the inner end of the conveying hole, the clamping plates are slidably connected to two sets of guide rails, the guide rails are fixedly installed on the inner wall of the cutting box, and a first cylinder is fixedly installed on the outer wall of the cutting box to drive the clamping plate; After one end of the steel ingot is cut, the process of releasing the steel ingot from its fixed position, moving the steel ingot forward, and fixing the steel ingot again is required. This greatly reduces the non-cutting auxiliary time of the steel ingot and improves the cutting efficiency of the steel ingot end. Secondly, during the cutting of the other end of the steel ingot, the next set of steel ingots can be placed on the first conveying mechanism, and the processed steel ingots can be taken off from the third conveying mechanism, saving the time of loading and unloading the steel ingots and further improving the cutting efficiency of the steel ingot end.

[0007] Preferably, two sets of through holes are symmetrically opened on the lifting plate, and the through holes are slidably connected to the guide posts, which are fixedly installed on the cutting box; As the lifting plate moves downward, the through holes on the lifting plate will slide along the guide post, guiding the movement of the lifting plate.

[0008] Preferably, a first positioning component is provided inside the cutting box. The first positioning component includes a second cylinder, which is fixedly installed inside the cutting box. A first positioning plate is fixedly connected to the output end of the second cylinder. Two sets of guide sleeves are symmetrically arranged on both sides of the first positioning component. A slide rod is slidably connected to the guide sleeves. The slide rod is fixedly installed inside the cutting box. A second positioning component is provided on the second conveying mechanism. The second positioning component includes a bracket, which is fixedly installed on the second conveying mechanism. A second positioning plate is slidably installed on the bracket. A third cylinder is fixedly installed on the bracket to drive the second positioning plate. Pressure sensors for positioning the end of the steel ingot are installed on both the first positioning plate and the second positioning plate. By coordinating the first positioning plate, the second positioning plate, and the pressure sensor, precise positioning of both ends of the steel ingot is achieved, ensuring that the cutting amount at the ends of the steel ingot remains consistent and improving the automation rate of the device.

[0009] Preferably, the first positioning plate includes a plate frame, two sets of guide sleeves respectively installed on both sides of the plate frame, a support plate movably installed on the plate frame, a pressure sensor fixedly installed on the support plate, two sets of insert plates symmetrically and movably inserted into the plate frame, two sets of insert plates connected to both ends of a horizontal plate, an output end of a second cylinder connected to the insert plates, a pressure plate fixedly connected to the lower end of the insert plates, a spring set below the pressure plate, a rectangular groove opened on the plate frame, two sets of slide rails provided on both sides of the rectangular groove, two sets of slide grooves opened on both sides of the support plate, the slide rails slidably connected to the slide grooves, an oblique groove opened on the insert plate, a receiving shaft provided on both sides of the support plate, the end of the receiving shaft located in the oblique groove, and the support shaft driven along the oblique groove to move the support plate; When one end of the steel ingot is pressed against the pressure sensor on the pallet, the second cylinder pulls the horizontal plate. Under the action of the spring rebound force, the pallet and the pressure sensor are pushed back into the rectangular groove, releasing the pressure sensor from contact with one end of the steel ingot. This avoids damage to the pressure sensor caused by friction and improves the service life of the pressure sensor.

[0010] The beneficial effects of this invention are as follows: 1. After one end of the steel ingot is cut, the process of releasing the steel ingot from its fixed position, moving the steel ingot forward, and fixing the steel ingot again is required. This greatly reduces the non-cutting auxiliary time of the steel ingot and improves the cutting efficiency of the steel ingot end. Secondly, during the cutting of the other end of the steel ingot, the next set of steel ingots can be placed on the first conveying mechanism, and the processed steel ingots can be taken off from the third conveying mechanism, saving the time of loading and unloading the steel ingots and further improving the cutting efficiency of the steel ingot end.

[0011] 2. When the second cylinder drives the first positioning plate to move downward, the second cylinder pushes the horizontal plate to move the entire first positioning plate downward. When the guide sleeve is blocked by the end of the slide rod and cannot continue to move, the second cylinder pushes the horizontal plate to make the two sets of insert plates continue to move downward. The insert plates compress the spring through the pressure plate. During this process, the two sets of receiving shafts will slide along the corresponding inclined groove. Under the guidance of the inclined groove, the receiving shaft drives the support plate to move along the slide rail to the outside of the rectangular groove, so that the front of the support plate is flush with the front of the plate frame. Therefore, when one end of the steel ingot is pressed against the pressure sensor on the support plate, the second cylinder pulls the horizontal plate. Under the action of the spring rebound force, the support plate and the pressure sensor enter the rectangular groove again, releasing the contact between the pressure sensor and one end of the steel ingot, thereby avoiding damage to the pressure sensor caused by friction and improving the service life of the pressure sensor.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] Example 1: As Figures 1 to 3As shown in the embodiment of the present invention, a cylindrical steel ingot end cutting device includes a cutting box 1, a first conveying mechanism 2 arranged at the rear of the cutting box 1, a second conveying mechanism 3 and a third conveying mechanism 4 arranged sequentially at the front of the cutting box 1, a discharge port 5 opened on one side of the lower end of the cutting box 1, a feeding box 6 placed below the discharge port 5, an inclined plate 7 fixedly installed inside the discharge port 5, a cutting mechanism 9 installed on the cutting box 1, and conveying holes 10 opened on both the front and rear sides of the cutting box 1, a fixing mechanism 11 for clamping the steel ingot is arranged at the inner end of the conveying hole 10, the cutting mechanism 9 includes a lifting plate 901 movably inserted into the cutting box 1, and a hydraulic system fixedly installed on the cutting box 1 for driving the lifting plate 901. The device includes a pressure cylinder 902, a cutting blade 903 rotatably mounted at the lower end of the lifting plate 901, two sets of synchronous gears 904 rotatably mounted on the lifting plate 901, both sets of synchronous gears 904 meshing with a synchronous belt 905, a motor 906 fixedly mounted at the upper end of the lifting plate 901 for driving one set of synchronous gears 904, and the cutting end connected to another set of synchronous gears 904. The fixing mechanism 11 includes two sets of clamping plates 111, which are symmetrically distributed on both sides of the inner end of the conveying hole 10. The clamping plates 111 are slidably connected to two sets of guide rails 112, which are fixedly mounted on the inner wall of the cutting box 1. A first cylinder 113 is fixedly mounted on the outer wall of the cutting box 1 for driving the clamping plates 111.

[0024] Specifically, the cutting box 1 is made of transparent tempered glass. The first conveying mechanism 2, the second conveying mechanism 3, and the third conveying mechanism 4 have the same structure. They all adopt the mechanism composed of support rods, rollers, driven sprockets, chains, drive sprockets, and motors from the cylindrical steel ingot end cutting device of the aforementioned patent. When it is necessary to cut the end of the steel ingot, the steel ingot is placed on the first conveying mechanism 2. The first conveying mechanism 2 moves the steel ingot towards the cutting box 1, so that the end of the steel ingot passes through a set of conveying holes 10 and enters the cutting box 1 until the end of the steel ingot moves below the cutting blade 903. Then, a set of fixing mechanisms 11 near the first conveying mechanism 2 is activated, and the two sets of... A cylinder 113 drives two sets of clamping plates 111 to move towards each other along corresponding guide rails 112, clamping the steel ingot and fixing it in place. Then, a motor 906 drives a set of synchronous gears 904 to rotate. These gears, via a synchronous belt 905, drive another set of synchronous gears 904 and the cutting blade 903 to rotate together. Next, a hydraulic cylinder 902 drives a lifting plate 901 and the rotating cutting blade 903 to move downwards, cutting off one end of the steel ingot. The resulting scrap falls onto the lower inclined plate 7 and rolls down into the discharge box 6 for scrap recovery. The cutting plate is then withdrawn. Cutting blade 903 releases the fixing mechanism 11 from the steel ingot. Then, the first conveying mechanism 2 continues to convey the steel ingot, moving it to the second conveying mechanism 3. The second conveying mechanism 3 simultaneously conveys the steel ingot until the other end of the steel ingot is below the cutting blade 903. At this point, the steel ingot is fixed by another fixing mechanism 11. Then, the cutting mechanism 9 cuts the other end of the steel ingot. During the cutting process, the next set of steel ingots can be placed on the first conveying mechanism 2. After cutting, the fixing mechanism 11 is released from the steel ingot, the cutting blade 903 is withdrawn again, and the processed steel ingot is conveyed to the second conveying mechanism 3. On the third conveying mechanism 4, during the cutting of the next set of steel ingots, the steel ingots on the third conveying mechanism 4 can be removed to realize the unloading of the workpiece. The above operation is repeated. Compared with the prior art, after the steel ingot is cut at one end, it is necessary to perform the process of releasing the steel ingot fixation, moving the steel ingot forward, and fixing the steel ingot. This greatly reduces the non-cutting auxiliary time of the steel ingot and improves the cutting efficiency of the steel ingot end. Secondly, during the cutting of the other end of the steel ingot, the next set of steel ingots can be placed on the first conveying mechanism 2, and the processed steel ingots can be removed from the third conveying mechanism 4, saving the steel ingot loading and unloading time and further improving the cutting efficiency of the steel ingot end.

[0025] Furthermore, two sets of through holes 9011 are symmetrically provided on the lifting plate 901. The through holes 9011 are slidably connected to the guide post 9012, and the guide post 9012 is fixedly installed on the cutting box 1.

[0026] Specifically, during the downward movement of the aforementioned lifting plate 901, the through hole 9011 on the lifting plate 901 will slide along the guide post 9012, which will guide the movement of the lifting plate 901.

[0027] like Figure 4 and Figure 5 As shown, a first positioning component 12 is provided inside the cutting box 1. The first positioning component 12 includes a second cylinder 121, which is fixedly installed inside the cutting box 1. A first positioning plate 122 is fixedly connected to the output end of the second cylinder 121. Two sets of guide sleeves 123 are symmetrically arranged on both sides of the first positioning component. A slide rod 124 is slidably connected to the guide sleeve 123. The slide rod 124 is fixedly installed inside the cutting box 1. A second positioning component 13 is provided on the second conveying mechanism 3. The second positioning component 13 includes a bracket 131, which is fixedly installed on the second conveying mechanism 3. A second positioning plate 133 is slidably installed on the bracket 131. A third cylinder 132 is fixedly installed on the bracket 131 to drive the second positioning plate 133. Pressure sensors 8 for positioning the end of the steel ingot are installed on both the first positioning plate 122 and the second positioning plate 133.

[0028] Specifically, when the steel ingot is moved under the cutting blade 903, the staff needs to judge the position of the steel ingot. Due to the error in the staff's judgment, it is difficult to keep the cutting amount at the end of the steel ingot consistent, which not only reduces the automation rate of the equipment, but also causes waste of steel ingots. The diameter of the end face of the pressure sensor 8 is larger than the cross-sectional diameter of the steel ingot. As the steel ingot moves from the first conveying mechanism 2 into the cutting box 1, the second cylinder 121 drives the first positioning plate 122 to move downwards. The first positioning plate 122 drives the guide sleeve 123 to slide downwards along the slide rod 124 until the guide sleeve 123 is blocked by the end of the slide rod 124 and can no longer move. As the steel ingot enters the cutting box 1, one end of the steel ingot is blocked by the first positioning plate 122, and this blockage presses against the pressure sensor 8 on the first positioning plate 122. The pressure sensor 8 feeds a signal back to the controller of the device, thereby stopping the conveying of the steel ingot and then solidifying it. Then, the first positioning plate 122 is retracted to position one end of the steel ingot. As the steel ingot moves from the cutting box 1 to the second conveying mechanism 3, the second positioning plate 133 is driven downward by the third cylinder 132. Similarly, the second positioning plate 133 will block the movement of the steel ingot, and the cut surface will press the pressure sensor 8 on the second positioning plate 133, stopping the conveying of the steel ingot and achieving the positioning of the other end of the steel ingot. Through the coordinated setting of the first positioning plate 122, the second positioning plate 133, and the pressure sensor 8, the precise positioning of both ends of the steel ingot is achieved, which not only ensures that the cutting amount at the ends of the steel ingot is consistent, but also improves the automation rate of the device.

[0029] Example 2: Figures 6 to 8As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the first positioning plate 122 includes a plate frame 1221, two sets of guide sleeves 123 are respectively installed on both sides of the plate frame 1221, a support plate 1222 is movably installed on the plate frame 1221, a pressure sensor 8 is fixedly installed on the support plate 1222, two sets of insert plates 1223 are symmetrically and movably inserted into the plate frame 1221, the two ends of the horizontal plate 1224 are connected to the two sets of insert plates 1223, the output end of the second cylinder 121 is connected to the insert plates 1223, and the lower end of the insert plates 1223 is fixedly connected. The pressure plate 1225, the spring 1226 located below the pressure plate 1225, the plate frame 1221 has a rectangular groove 211, two sets of slide rails 212 are provided on both sides of the rectangular groove 211, the support plate 1222 has two sets of slide grooves 222 on both sides, the slide rails 212 are slidably connected to the slide grooves 222, the insert plate 1223 has an oblique groove 231, the support plate 1222 has a receiving shaft 221 on both sides, the end of the receiving shaft 221 is located in the oblique groove 231, and the support plate 1222 is moved by driving the receiving shaft 221 along the oblique groove 231.

[0030] Specifically, when the second positioning plate 133 is driven upward to release the obstruction to the end of the steel ingot, the end of the steel ingot is cut, making the end face relatively flat and smooth. When the second positioning plate 133 moves, the pressure sensor 8 on the second positioning plate 133 has little friction with the end face and will not affect the pressure sensor 8. However, when the first positioning plate 122 is driven to release the obstruction to the end of the steel ingot, the end face of the cast steel ingot is not flat, resulting in the end of the steel ingot and the pressure sensor 8 not being in ideal surface contact, but rather in multi-point or line contact. Since the steel ingot will be fixed, when the first positioning plate 122 is moved, the pressure sensor 8 will experience severe friction with the pressure sensor 8, resulting in a reduction in the service life of the pressure sensor 8. In the initial state, the support plate 1222, along with the pressure sensor 8, is located in the rectangular groove 211 on the plate frame 1221. The front of the support plate 1222 is not flush with the front of the plate frame 1221. When the second cylinder 121 drives the first positioning plate 122 to move downward, the second cylinder 121 pushes the horizontal plate 1224 to move the entire first positioning plate 122 downward. When the guide sleeve 123 is blocked by the end of the slide rod 124 and cannot continue to move, the second cylinder 121 pushes the horizontal plate 1224 to make the two sets of insert plates 1223 continue to move downward. The insert plates 1223 compress the spring 1226 through the pressure plate 1225. During this process, the two sets of receiving shafts 221 will... Sliding along the corresponding inclined groove 231, guided by the inclined groove 231, the receiving shaft 221 drives the support plate 1222 to move along the slide rail 212 towards the outside of the rectangular groove 211, so that the front of the support plate 1222 is flush with the front of the plate frame 1221. Therefore, when one end of the steel ingot is pressed against the pressure sensor 8 on the support plate 1222, the second cylinder 121 pulls the horizontal plate 1224. Under the rebound force of the spring 1226, the support plate 1222 and the pressure sensor 8 enter the rectangular groove 211 again, releasing the contact between the pressure sensor 8 and one end of the steel ingot, thereby avoiding damage to the pressure sensor 8 caused by friction and improving the service life of the pressure sensor 8.

[0031] Working principle: The steel ingot is placed on the first conveying mechanism 2, which moves the steel ingot towards the cutting box 1, so that the end of the steel ingot passes through a set of conveying holes 10 and enters the cutting box 1 until the end of the steel ingot moves below the cutting blade 903. Then, a set of fixing mechanisms 11 near the first conveying mechanism 2 is activated. Two sets of first cylinders 113 drive two sets of clamping plates 111 to move towards each other along the corresponding guide rails 112, so that the two sets of clamping plates 111 clamp the steel ingot and fix it. Then, the motor 906 drives a set of synchronous gears 904 to rotate. One set of synchronous gears 904 drives another set of synchronous gears 904 and the cutting blade 903 to rotate together through the synchronous belt 905. Then, the hydraulic cylinder 902 drives the lifting plate 901 and the rotating cutting blade 903 to move downward together, so that the cutting blade 903 cuts off one end of the steel ingot, and the waste generated by cutting falls onto the lower inclined plate 7, so that the waste is discharged along the inclined plate 7. The inclined plate 7 rolls into the feeding box 6 to recycle the waste material. Then, the cutting blade 903 is withdrawn, and a set of fixing mechanisms 11 is released from fixing the steel ingot. Then, the first conveying mechanism 2 continues to convey the steel ingot, moving it to the second conveying mechanism 3. The second conveying mechanism 3 simultaneously conveys the steel ingot until the other end of the steel ingot is below the cutting blade 903. At this time, the steel ingot is fixed by another set of fixing mechanisms 11. Then, the other end of the steel ingot is cut by the cutting mechanism 9. During the cutting of the other end of the steel ingot, the next set of steel ingots can be placed on the first conveying mechanism 2. After the cutting is completed, the other set of fixing mechanisms 11 is released from fixing the steel ingot, and the cutting blade 903 is withdrawn again. The processed steel ingot is conveyed to the third conveying mechanism 4 by the second conveying mechanism 3. During the cutting of the next set of steel ingots, the steel ingots on the third conveying mechanism 4 can be removed to unload the workpiece. The above operation is repeated. As the steel ingot moves from the first conveying mechanism 2 into the cutting box 1, the second cylinder 121 drives the first positioning plate 122 to move downward. The first positioning plate 122 drives the guide sleeve 123 to slide downward along the slide rod 124 until the guide sleeve 123 is blocked by the end of the slide rod 124 and cannot move further. As the steel ingot enters the cutting box 1, one end of the steel ingot is blocked by the first positioning plate 122, and the one end of the steel ingot presses the pressure sensor 8 on the first positioning plate 122. The pressure sensor 8 feeds the signal back to the controller of the device, thereby stopping the conveying of the steel ingot and fixing the steel ingot. Then the first positioning plate 122 is withdrawn to achieve the positioning of one end of the steel ingot. As the steel ingot moves from the cutting box 1 into the second conveying mechanism 3, the third cylinder 132 drives the second positioning plate 133 to move downward. Similarly, the second positioning plate 133 will block the movement of the steel ingot, and the cut surface will press the pressure sensor 8 on the second positioning plate 133 to stop the conveying of the steel ingot and achieve the positioning of the other end of the steel ingot. When the second cylinder 121 drives the first positioning plate 122 to move downward, the second cylinder 121 pushes the horizontal plate 1224 to move the entire first positioning plate 122 downward. When the guide sleeve 123 is blocked by the end of the slide rod 124 and cannot continue to move, the second cylinder 121 pushes the horizontal plate 1224 to make the two sets of insert plates 1223 continue to move downward. The insert plates 1223 compress the spring 1226 through the pressure plate 1225. During this process, the two sets of receiving shafts 221 will slide along the corresponding inclined grooves 231. Guided by the inclined groove 231, the receiving shaft 221 drives the support plate 1222 to move along the slide rail 212 towards the outside of the rectangular groove 211, so that the front of the support plate 1222 is flush with the front of the plate frame 1221. Therefore, when one end of the steel ingot is pressed against the pressure sensor 8 on the support plate 1222, the second cylinder 121 pulls the horizontal plate 1224. Under the action of the spring 1226, the support plate 1222 and the pressure sensor 8 enter the rectangular groove 211 again, releasing the contact between the pressure sensor 8 and one end of the steel ingot.
