Abstract
Description
Technical Field
[0001] This utility model relates to a cleaning device, and more particularly to a device capable of cleaning the cutting nodules at the ends of continuously cast billets after cutting, belonging to the technical field of continuous casting billet cutting nodule cleaning equipment. Background Technology
[0002] During continuous casting, the billet needs to be cut to length. Flame cutting is typically used to cut the billet, the principle of which is to heat the billet to its melting point and then cut it. During cutting, molten combustion products adhere to the lower surface of the billet. After cooling, these products form burrs, cutting nodules, and other difficult-to-remove substances. If these substances are not cleaned properly, they can cause defects such as foreign object indentation and voids during subsequent rolling. Therefore, a deburring machine is needed to remove them. However, in actual production, the billet may experience curling or other issues due to external environmental factors, making it impossible to control the deburring machine opening online in real time, thus affecting the deburring effect. Therefore, a cleaning device is needed that can efficiently remove the cutting nodules from the continuous casting billet. Utility Model Content

[0016] See Figure 1 and Figure 2 This utility model includes a clamping mechanism, a U-shaped long plate 1, a lateral movement mechanism, a slag tray 2, an adjustment mechanism, and a cleaning mechanism. Two clamping mechanisms are symmetrically arranged on both sides of the continuous casting billet's width. The U-shaped long plate 1 is positioned between the two clamping mechanisms. The cooperation between the clamping mechanisms and the U-shaped long plate 1 allows the device to be relatively fixed on the continuous casting billet, facilitating subsequent cleaning operations. The lateral movement mechanism is mounted on the U-shaped long plate 1. This mechanism drives the slag tray 2, adjustment mechanism, and cleaning mechanism to move laterally, cleaning the cutting edge along the way. The slag tray 2 is mounted on the lateral movement mechanism to receive the cleaned-off slag, preventing it from falling to the ground and affecting the work environment. The adjustment mechanism is mounted on the slag tray 2, and the cleaning mechanism is mounted on the adjustment mechanism. The adjustment mechanism can adjust the orientation of the cleaning mechanism to align it with the cutting edge, ensuring smooth cleaning operations.
[0017] The clamping mechanism includes a top plate 3, a vertical plate 4, a screw 5, a top plate 6, and a handle 7. The top plate 3 is located on the top surface of the vertical plate 4, and the bottom surface of the top plate 3 presses against the top surface of the continuously cast billet. The vertical plate 4 is provided with a threaded hole, and the screw 5 passes through the threaded hole of the vertical plate 4. One end of the screw 5 is provided with the top plate 6, and the other end is provided with the handle 7. The top plate 6 presses against the side wall of the continuously cast billet. A U-shaped long plate 1 is connected between the two vertical plates 4, and the U-shaped long plate 1 is located directly below the continuously cast billet. When the top plates 3 on both sides press against the continuously cast billet, the screws 5 on both sides are rotated so that the two top plates 6 press tightly against the side wall of the continuously cast billet, thereby fixing the relative position between the device and the continuously cast billet.
[0018] The lateral movement mechanism includes a motor 8, a lead screw, a lead screw nut, and a square sliding sleeve 9. The motor 8 is mounted on the outer wall of the vertical plate 4. The two ends of the lead screw are respectively axially connected to the side walls of the vertical plate 4 on both sides, and the output shaft of the motor 8 is connected to one end of the lead screw. The lead screw is located in the inner cavity of the U-shaped long plate 1. The lead screw nut is mounted on the lead screw and is located inside the U-shaped long plate 1. The motor 8 can drive the lead screw to rotate, thereby driving the lead screw nut to slide within the U-shaped long plate 1 along the axis of the lead screw. The square sliding sleeve 9 is sleeved on the outer wall of the U-shaped long plate 1, and the lead screw nut is connected to the square sliding sleeve 9. The square sliding sleeve 9 moves synchronously with the lead screw nut.
[0019] The slag pan 2 is mounted on the square sliding sleeve 9, with its opening facing upwards; the slag pan 2 is located directly below the cutting edge of the continuously cast billet.
[0020] The adjustment mechanism includes side plates 10, a rotating shaft 11, a positioning plate, and bolts. There are two side plates 10, which are symmetrically arranged on both sides of the upper end face of the slag pan 2 along the width direction of the continuously cast billet. The two ends of the rotating shaft 11 are respectively axially connected between the two side plates 10. The rotating shaft 11 adjusts the position of the flame torch 12 and the L-shaped scraper 15 by rotating, so that they can be aligned with the edge line where the cutting edge is located. One end of the rotating shaft 11 is provided with a round rod, which passes through the side plate 10 and the end of the round rod is connected to the positioning plate. The positioning plate is provided with a threaded hole, and the bolt passes through the threaded hole of the positioning plate and presses against the side plate 10. Tightening the bolt can fix the position of the rotating shaft 11.
[0021] The cleaning mechanism includes a scraper and a flame gun 12; both the scraper and the flame gun 12 are mounted on the circumferential sidewall of the rotating shaft 11; the flame gun 12 melts the cutting nodules, thus facilitating the subsequent removal operation by the L-shaped scraper 15.
[0022] The slag scraper includes a guide post 13, a slide rod 14, and an L-shaped scraper 15. The guide post 13 is disposed on the circumferential side wall of the rotating shaft 11, and its end is provided with a guide hole. The slide rod 14 is inserted into the guide hole at the end of the guide post 13. A spring is provided at the bottom of the inner wall of the guide hole, and the end of the spring is connected to the end of the slide rod 14. The spring provides a force to the slide rod 14 to approach the continuously cast billet, ensuring that the L-shaped scraper 15 reliably presses against the edge where the slag is located. The end of the slide rod 14 away from the guide post 13 is provided with a hinge seat, and the center of the L-shaped scraper 15 and the hinge seat form a hinged connection structure. The presence of the hinge seat allows the L-shaped scraper 15 to fit well against the edge where the slag is located.
[0023] Operating principle: When it is necessary to clean the cutting edge, place the top plates 3 on both sides of the upper end face of the continuous casting billet, adjust the position so that the U-shaped long plate 1 is close to the cutting edge, and the slag plate 2 is located directly below the cutting edge. Then rotate the screw 5 so that the top plate 6 presses against the side wall of the continuous casting billet. After the screws 5 on both sides are tightened, the position of the U-shaped long plate 1 is relatively fixed. Then rotate the shaft 11 to adjust the position of the flame torch 12 so that it can be aligned with the cutting edge. Then tighten the bolt to fix the position of the shaft 11. Then adjust the position of the L-shaped scraper 15 so that it touches the edge line of the cutting edge. Then ignite the flame torch 12 and start the motor 8. The flame torch 12 melts the cutting edge in front, and the L-shaped scraper 15 scrapes away the molten cutting edge from behind, scraping the slag onto the slag plate 2 until all the cutting edge is cleaned. Then turn off the flame torch 12, rotate the screws 5 on both sides, and remove the device. At this point, the cutting edge of the continuous casting billet has been cleaned.
