Description

Technical Field

[0001] The utility model relates to the technical field of waste recycling of cutting machines, and more specifically to a waste recycling mechanism of a flame cutting machine. Background Art

[0002] Flame cutting machine is a cutting machine equipment in the mechanical processing industry. Its working characteristics are cutting large-section square billets, slabs and large tube billets, and also used to cut finished steel plates with a thickness greater than 50mm. According to the metal material and the thickness of the cut metal, from a process point of view, it is generally recommended to use flame cutting for carbon steel plates above 5mm, because such steel plates produce very little thermal deformation. The flame cutting machine uses the flame heat energy of the mixed combustion of combustible gas and oxygen to preheat the workpiece cutting part to a certain temperature, and then sprays a high-speed cutting oxygen flow to cause the metal to oxidize violently and release heat. The flame cutting oxygen flow is used to blow off the molten metal oxides, thereby achieving cutting. The cutting temperature can reach 2500 degrees to 3500 degrees. The molten cutting slag produced by the flame cutting machine will flow to the cutting bracket and the ground below the bracket. The cooled cutting slag is combined with the ground or the cutting bracket. The work of removing the cutting slag is very hard and wastes manpower, which will affect the production and processing progress.

[0003] The existing Chinese utility model patent with announcement number CN205650930U discloses an automatic slag cleaning device for a flame cutting machine, including slag buckets installed on both sides of the flame cutting machine, and a slag collecting trough located below the flame cutting machine and connected to the slag buckets on both sides at the same time, cooling water is stored in the slag bucket and the slag collecting trough, and a slag pulling plate is slidably arranged on the bottom plate of the slag collecting trough, and the slag pulling plate can move left and right on the upper surface of the bottom plate of the slag collecting trough under the drive of the driving mechanism. The slag collecting trough of the automatic slag cleaning device of the utility model is obviously not movable, that is, it covers the entire bottom of the flame cutting machine. Similarly, the slag pulling plate also needs to cover the entire area of ​​the bottom of the flame cutting machine. A lot of water needs to be added to the slag collecting trough to cover the entire slag collecting trough, and the slag bucket must be the same length as the left and right sides of the cutting machine; however, the effective cutting area of ​​the flame cutting machine often only occupies a part of the entire flame cutting machine cuttable area. Therefore, the automatic slag cleaning device for the flame cutting machine of the utility model has a large structure, occupies a large space, wastes unnecessary power source and water, and greatly increases the production cost and maintenance cost.
