Description

Technical Field

[0001] This application relates to the field of rolling mill equipment technology, and in particular to a steel bar cleaning device for a double-cutting shearing machine. Background Technology

[0002] To ensure the quality of cold-rolled products, continuous production on the production line greatly stabilizes process parameters. Therefore, welding equipment is installed at the production line entrance to weld two coils of strip steel together, thus ensuring continuous production. A narrow lap welding machine is one effective method. Its welding principle involves overlapping two pieces of material (strip steel), applying an appropriate current under the pressure of the welding wheel, and generating heat through the resistance of the material itself, the concentrated resistance between the materials, and the contact area between the material and the electrode. This heat eventually melts the material, connecting the two strips together. Equipping the welding machine with double shears to cut the ends of the two coils before welding effectively ensures a smooth and flat lap surface, guaranteeing weld quality.

[0003] During the welding process of narrow-lap resistance welding machines, a large current flows through the welding wheel, creating a magnetic field around it. This magnetizes the welding machine body, with particularly severe magnetization in the shear blade area. After shearing, small strips of welding waste easily adhere to the shear blade sidewall or the sheared strip, preventing proper waste removal and causing steel jamming. This is especially problematic during thin-gauge production, severely impacting the smooth operation of the production line. When this occurs, production personnel must manually move the welding machine carriage to the drive side to remove it, significantly disrupting production and potentially causing shutdowns, increasing the safety risks associated with abnormal operation.

[0032] The air source 100 is used for supplying compressed air; the air source 100 is a power source, and the main function is to provide stable and certain pressure compressed air. Specifically, the air compressor or other air source 100 equipment can be used to compress air to a set pressure value, providing power support for subsequent blowing operation.

[0033] As Figure 1 , Figure 2 indicated, the pipeline 200 has one end connected with the air source 100, and the inside of the pipeline 200 is provided with a channel to make the compressed air enter the pipeline 200.

The channel provided in the inside of the pipeline 200 is used for conveying compressed air. The channel ensures that the compressed air maintains stable flow rate and pressure during transmission, avoiding pressure loss caused by pipeline resistance. Through the layout of the pipeline 200, the compressed air can be efficiently distributed to each nozzle 301, so as to realize comprehensive blowing of the area of the lower shear blade 401.
