Description

Technical Field

[0001] This invention relates to the field of ladle venting core processing technology, and in particular to a ladle venting core processing device. Background Technology

[0002] A ladle permeable core brick is a cone-shaped object with a 2mm thick steel shell, an internal air core, chromium corundum material, and an air bladder at the bottom. The ladle permeable core is a key device used in ladle refining processes in steelmaking. It is installed at the bottom of the ladle, and argon gas passes through it to agitate the molten steel during converter tapping or LF smelting, thereby achieving smelting objectives such as uniform temperature, composition, and removal of floating inclusions in the molten steel.

[0003] In the manufacturing process of the steel ladle venting core, the main steps are to install a conical steel ladle on the outer wall of the formed venting core, cut off the excess parts at both ends of the conical steel ladle, and then weld the mounting rod and sealing plate on. However, existing steel ladle venting cores mainly use manual cutting with a handheld cutting machine to remove excess parts at both ends of the conical steel ladle. This requires workers to hold the cutting machine around the steel ladle to make the cut, and after the cut is completed, workers still need to perform other operations, requiring frequent picking up and putting down of the cutting machine, which is time-consuming and labor-intensive. Moreover, the cut surface is prone to being uneven, which affects the quality of subsequent welding.

[0004] Therefore, a steel ladle venting core processing device is proposed to solve the above problems. Summary of the Invention

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0021] like Figure 1-9The device for processing a steel ladle venting core includes a base 1, a support frame 2 fixedly connected to the top of the base 1, a placement groove 3 for placing one end of a conical steel ladle on the top of the base 1, a cylinder 4 rotatably connected through the top of the support frame 2, a rectangular frame 5 fixedly connected to the bottom of the cylinder 4, a rotary motor 6 fixedly connected to the bottom of the support frame 2, a gear ring 7 fixedly connected to the outer wall of the cylinder 4, a gear 8 meshing with the gear ring 7 and passing through the top of the support frame 2 and fixedly connected to the output end of the rotary motor 6, and a pair of electric telescopic cylinders 9 fixedly connected to the top of the rectangular frame 5, with a pressing block 10 at the top of the inner end of the rectangular frame 5, the output end of the electric telescopic cylinder 9 passing through the top of the rectangular frame 5 and fixedly connected to the top of the pressing block 10, the pressing block 10 being inclined on both sides, and the inclined surface of the pressing block 10 being perpendicular to a right angle. The inclined surfaces of the blocks 13 fit together. Vertical grooves 11 are provided on both sides of the outer wall of the rectangular frame 5. The vertical grooves 11 limit the sliding position of the horizontal frame 12. The horizontal frame 12 is slidably connected between the vertical grooves 11. A pair of right-angle blocks 13 with inclined surfaces are slidably connected to the top of the horizontal frame 12 and inside the rectangular frame 5. The bottom of each right-angle block 13 is fixedly connected to an L-shaped rod 14 that passes through the bottom of the rectangular frame 5. The L-shaped rod 14 is provided with a cutting mechanism for cutting. The bottom of each vertical groove 11 is provided with a release groove 15 that matches the right-angle block 13. It should be noted that the width of the right-angle block 13 is wider than the width of the vertical groove 11, so that it will not move outward when the pressing block 10 presses the right-angle block 13. It can only slide to the sides when the right-angle block 13 moves to the release groove 15. A bottom tube 16 is fixedly connected through the bottom of the rectangular frame 5. The bottom tube 16 can be used to store the reset spring 17. The bottom of the horizontal frame 12 is fixedly connected to the bottom of the bottom tube 16. The right-angle block 13 has grooves 18 on both sides of its outer wall. The upper spring 19 is fixedly connected between the grooves 18. The upper spring 19 facilitates the quick reset of the right-angle block 13 by pulling it during reset. The cutting mechanism includes a cutting motor 20, and there is a pair of cutting motors 20. Both cutting motors 20 are fixedly connected to the top of the L-shaped rod 14. The output end of each cutting motor 20 passes through the bottom end of the L-shaped rod 14 and is fixedly connected to a cutting blade 21. During the processing of the steel ladle venting core, when it is necessary to cut off the excess part of the conical steel ladle, the conical steel ladle is first placed in the placement groove 3 for positioning. At this time, the worker needs to hold the steel ladle venting core. Then, the cutting motor 20 is started to drive the cutting blade 21 to rotate, and the electric telescopic cylinder 9 is started to drive the pressing block 10 to slide downward. At this time, because the width of the right-angle block 13 is greater than the width of the vertical groove 11, it cannot slide to the sides. Therefore, under the pressure of the pressing block 10, the right-angle block 13, the horizontal frame 12, the L-shaped rod 14, the cutting motor 20, and the cutting blade 21 will move downward and gradually compress the return spring 17. Then, the cutting blade 21 is inserted into the excess part of the conical steel ladle. At this time, the horizontal frame 12 moves to the bottom of the rectangular frame 5, thus being restricted from moving downward, and the right-angle block 13... Move to the release groove 15 to release the restriction on the right-angle block 13 to slide to both sides. Then, under the action of the pressure block 10 pressing the inclined surface of the right-angle block 13, the right-angle block 13 will be pressed to slide to both sides, which will drive the L-shaped rod 14 and the cutting blade 21 to slide to both sides, thereby cutting the ladle. When the cutting blade 21 cuts the conical ladle, the moving rod 30 will touch the corresponding touch sensor 36. Then, the controller will control the electric telescopic cylinder 9 to stop running and control the rotary motor 6 to start driving the gear 8 to rotate, which will drive the meshing gear ring 7 to rotate, and then drive the cylinder 4 and the rectangular frame 5 to rotate, thereby driving the cutting blade 21 to rotate, realizing the complete cutting of the excess part of the conical ladle. Finally, after the cutting is completed, control the electric telescopic cylinder 9 to start and reset, and repeat the above operation in reverse.

[0022] To further improve the stability of the device during operation, limit rods 22 are fixedly connected to both sides of the right-angle block 13 and the pressing block 10. The top of the limit rod 22 is flush with the top of the right-angle block 13. The limit rod 22 can limit the right-angle block 13 when it slides out of the release groove 15, so as to prevent the horizontal frame 12 from moving upward when the electric telescopic cylinder 9 is reset, thus affecting the normal reset of the right-angle block 13.

[0023] In order to limit the position of the bottom end of the conical steel ladle when cutting at the end with the largest diameter, a storage groove 23 is provided at the bottom of the placement groove 3. An annular block 24 for placing the other end of the conical steel ladle is slidably connected to the inner side of the storage groove 23, and the inner side of the annular block 24 is inclined. Several lower springs 25 are fixedly connected between the bottom of the storage groove 23 and the bottom of the annular block 24. The annular block 24 allows the shortest end of the conical steel ladle to be placed. The inner side of the annular block 24 is inclined, allowing it to fit against the outer wall of the conical steel ladle. When cutting the shortest end of the conical steel ladle, the air core of the ladle is placed on the annular block 24, which compresses the annular block 24 to slide downward inside the storage groove 23 and compresses the lower spring 25, thus placing the conical steel ladle in the placement groove 3 for positioning and cutting.

[0024] To allow for alternating cutting of both ends of the conical ladle, a long slot 26 and a short slot 27 are respectively provided on the inner side of the rectangular frame 5. The bottom end of the short slot 27 is positioned at the right-angle block 13 of the extrusion block 10, corresponding to the position of the moving rod 30 when the driving cutting blade 21 cuts to the shortest diameter end of the conical ladle. The bottom end of the long slot 26 is positioned at the position corresponding to the position of the moving rod 30 when the cutting blade 21 cuts the longest diameter end of the conical ladle. A sliding frame 28 is fixedly connected to the side wall of the extrusion block 10, and a sliding cylinder 29 is slidably connected to the inner side of the sliding frame 28. The moving rod 30 is slidably connected through the side wall of the sliding cylinder 29. A positioning spring 31 is fixedly connected between the inner sides of the moving cylinder 29. The end of the moving rod 30 is inserted into the inner side of the short groove 27. An upper inclined groove 34 is inclinedly opened between the top of the long groove 26 and the inner side of the short groove 27. A lower inclined groove 35 is inclinedly opened between the top of the short groove 27 and the inner side of the long groove 26. The depth of the lower inclined groove 35 is deeper than the depth of the upper inclined groove 34. The bottom end of the upper inclined groove 34 is inclined at the connection with the short groove 27. The bottom end of the lower inclined groove 35 is inclined at the connection with the long groove 26. A touch sensor 36 is fixedly connected through the bottom ends of both the long groove 26 and the short groove 27. The touch sensor 36 is electrically connected to the rotary motor 6 and the electric telescopic cylinder 9 through the controller. Furthermore, the end of the moving rod 30 is designed with a smooth arc surface, which facilitates the smoother sliding of the moving rod 30 out of the positioning groove 37, the upper inclined groove 34 and the lower inclined groove 35. The upper inclined groove 34 and the lower inclined groove 35 are arranged intersectingly. The top of the long groove 26 and the short groove 27 are both provided with recessed positioning grooves 37. The bottom of the positioning grooves 37 are all inclined. The positioning grooves 37 are designed to guide the moving rod 30 when it slides into the long groove 26 or the short groove 27, preventing it from continuing to slide into the upper inclined groove 34 or the lower inclined groove 35, thereby improving the stability of the device during operation. Both ends of the lower inclined groove 35 are fixedly connected to a base plate 32 at positions corresponding to the upper inclined groove 34. The base plate 32 prevents the moving rod 30 from falling into the lower inclined groove 35 when passing through the upper inclined groove 34, thus affecting the normal operation of the device. A pair of top plates 38 are fixedly connected to the inner side of the upper inclined groove 34 above the base plate 32. The top plates 38 prevent the upper inclined groove 34 from pressing and moving the moving rod 30. The outer wall of the moving rod 30 is provided with an annular groove 33 at positions corresponding to the base plate 32 and the top plate 38. The annular groove 33 prevents the moving rod 30 from being obstructed when passing through the top plate 38 and the base plate 32. It should be noted that when the moving rod 30 moves in the upper inclined groove 34, the annular groove 33 at the rear end of the moving rod 30 will pass through the top plate 38. During the cutting process of the ladle, as the electric telescopic cylinder 9 drives the extrusion block 10 to slide downwards, it simultaneously moves the sliding frame 28, the sliding cylinder 29, and the moving rod 30 downwards, driving the moving rod 30 to slide inside the short groove 27. The moving rod 30, initially positioned, is inserted into the positioning groove 37 at the top of the short groove 27. Driven by the electric telescopic cylinder 9, the moving rod 30 slides downwards, its outward movement compressed by the inclined surface of the positioning groove 37, compressing the positioning spring 31. Subsequently, when the electric telescopic cylinder 9 drives the moving rod 30 to the bottom of the upper inclined groove 34, the spring force of the positioning spring 31 pushes the moving rod 30 into the upper inclined groove 34, and then... As the 0 continues to move downward, it will be squeezed by the inclined surface at the bottom of the upper inclined groove 34, pushing the moving rod 30 to slide outward again and compressing the positioning spring 31. Then, when the squeezing block 10 squeezes the right-angle block 13 to the release groove 15, the right-angle block 13 will slide outward through the inclined surface of the squeezing block 10. When the cutting blade 21 cuts the conical steel ladle, the squeezing block 10 drives the moving rod 30 to move downward. The end of the moving rod 30 will touch one of the touch sensors 36. Then the touch sensor 36 transmits the signal to the controller. The controller controls the electric telescopic cylinder 9 to stop running and controls the rotary motor 6 to start, thereby realizing the automatic cutting of the steel ladle. After the cutting is completed, the electric telescopic cylinder 9 is controlled to start and reset. During the reset process, the moving rod 30 slides upward. When the moving rod 30 slides to the bottom of the upper inclined groove 34, it is pushed back into the upper inclined groove 34 by the elastic force of the positioning spring 31. However, due to the step between the top of the upper inclined groove 34 and the short groove 27, the moving rod 30 cannot continue to slide upward. Under the continued pulling of the electric telescopic cylinder 9, the upper inclined groove 34 will squeeze the moving rod 30, causing the sliding cylinder 29 to slide within the sliding frame 28. Subsequently, when the moving rod 30 passes above the lower inclined groove 35, the top plate 38 will insert into the annular groove 33, maintaining the compression of the moving rod 30. At the same time, the bottom of the moving rod 30 passes above the bottom plate 32 and then slides into the other half of the upper inclined groove 34. The moving rod 30 slides to the connection point between the top of the upper inclined groove 34 and the long groove 26, and then the moving rod 30 is positioned next to the positioning groove 37. Under the elastic force of the positioning spring 31, the moving rod 30 is pushed into the positioning groove 37, which limits the sliding position of the moving rod 30. Subsequently, under the push of the electric telescopic cylinder 9, the moving rod 30 can be driven to slide out of the positioning groove 37 and into the long groove 26, thereby driving the extrusion block 10 to slide down a longer distance, and thus extruding the right-angle block 13 to slide a wider distance to both sides. This allows for alternating cutting of both ends of the conical steel ladle, realizing alternating changes in the outward expansion length of the cutting blade 21, without the need for worker adjustments, further improving the convenience of the device.
