Description

Technical Field

[0001] This utility model relates to a cleaning device, and more particularly to a device that can clean the cutting slag generated at the edge of a steel billet during the cutting process, belonging to the technical field of steel billet edge cutting slag cleaning equipment. Background Technology

[0002] The length of steel billets is subject to requirements. The precursor to the steel billet, the continuously cast billet, is quite long. To meet this requirement, the continuously cast billet needs to be cut. Currently, this cutting is done using a flame cutting torch. Workers hold the torch and cut the billet along the cutting line. During this process, the high temperature of the flame causes the steel to melt through, and some of the molten metal oxides solidify at the upper and lower edges of the cut seam under the influence of the oxygen flow. To meet factory requirements, the cutting slag at the cut seam edges needs to be cleaned. Currently, this is done manually, which is inefficient, time-consuming, and the hardened slag is even more difficult to remove. Therefore, a cleaning device is needed that can efficiently clean the cutting slag at the cut seam edges of the steel billet. Utility Model Content

When the upper horizontal rod moves forward above the billet, the traveling wheel ensures that the upper horizontal rod remains straight and does not bend, avoiding bending of the upper horizontal rod due to its excessive length, which would affect the cutting operation and the removal of cutting edge.

[0020] The lower displacement mechanism includes a lower horizontal rod 7 and a sleeve 8; a guide hole is provided at the center of the bottom end of the side wall of the column 3, and the lower horizontal rod 7 is inserted into the guide hole at the bottom end of the column 3; the guide hole at the bottom end of the column provides guidance for the lower horizontal rod; the center line of the lower horizontal rod 7 is parallel to the center line of the upper horizontal rod 4, and the center point of the lower horizontal rod 7 is located directly below the midpoint of the line connecting the center points of the two lower horizontal rods 7; one end of the lower horizontal rod 7 is connected to the connecting strip 5 through a bracket; the sleeve 8 is sleeved on the end of the lower horizontal rod 7 away from the connecting strip 5; a threaded hole is provided on the side wall of the sleeve 8, and a bolt passes through the threaded hole on the side wall of the sleeve 8 and presses against the lower horizontal rod 7, and tightening the bolt can fix the position of the sleeve; the position of the lower cleaning part can be adjusted by sliding the sleeve, thereby ensuring that the lower cleaning part can remove the cutting slag at the lower edge in a suitable position.

A spring is provided at the bottom of the inner wall of the square tube 14, and the spring is connected to the bottom of the vertical rod 15. The spring provides an upward force to the vertical rod, ensuring that the traveling wheels on the flat plate can reliably press against the bottom surface of the billet, and the cutting seam of the billet is located between the two traveling wheels. The flat plate 16 is located on the top surface of the vertical rod 15. The upper plate 16 is perpendicular to the center line of the lower horizontal rod 7.

[0024] The working principle of this utility model is as follows:

[0025] When it is necessary to cut the steel billet, confirm the position of the cutting line, then push the device to a position next to the steel billet cutting line, then push the base close to the steel billet, adjust the position of the base so that the lower horizontal long rod is aligned with the steel billet cutting line, and the flame cutting gun is located directly above the cutting line; at this time, the traveling wheel at the end of the upper horizontal long rod is pressed against the top surface of the steel billet; then start the motor to adjust the position of the flame cutting gun so that it is aligned with the edge line of the steel billet, and then adjust the vertical height of the flame cutting gun so that it can maintain a reasonable distance from the top surface of the steel billet;

[0026] After the position is adjusted, start the flame cutting gun and the upper blow gun. The flame cutting gun cuts the steel billet, and the upper blow gun blows away the cutting edge on the upper edge of the steel billet. Start the motor to drive the upper and lower horizontal rods to move slowly along the steel billet cutting line. During the movement, the flame cutting gun cuts a slit on the steel billet cutting line.

[0027] Since the flame cutting gun is in front and the lower cleaning part is slightly behind, the lower cleaning part does not contact the steel billet in the initial stage. After the flame cutting gun moves forward a short distance, the lower cleaning part contacts the steel billet. At this time, under the action of the spring, the traveling wheel on the plate presses against the bottom surface of the steel billet, and the lower blowing gun blows away the cutting edge on the lower edge of the steel billet.

[0028] Once the flame cutting torch has moved to its end and the billet has been cut, shut off the flame cutting torch, the upper blower, and the lower blower. Then, reverse the motor to reset all parts. After the flame cutting torch detaches from the billet, remove the device. This completes the removal of the cutting edge during the billet cutting process.
