Description

Technical Field

[0001] This utility model relates to an automatic grinding device for rough edges of welding wire steel strip, belonging to the technical field of welding wire steel strip processing devices. Background Technology

[0002] Flux-cored welding wire consists of a steel strip encasing the flux core. During manufacturing, burrs inevitably form on the steel strip. If these burrs are not treated, the internal structure of the flux-cored wire may become uneven during subsequent rolling. Furthermore, burrs reduce the wire's airtightness, leading to moisture absorption of the flux core. During welding, this moisture evaporates, creating porosity and causing grooves or cracks in the weld. Burrs also increase surface friction, causing the wire feed mechanism to jam or fluctuate feed speed, affecting welding continuity and stability. Especially in high-precision automated welding, burrs can cause welding torch deviation and poor weld formation. Additionally, burrs disrupt the smoothness of the wire surface, causing the arc to concentrate at the burrs, resulting in unstable droplet transfer, increased spatter, and a rough weld surface. Therefore, burrs on the steel strip of flux-cored welding wire are a critical quality control point in the manufacturing process. In existing processes, the removal of burrs from steel strips is mostly done manually, which is inefficient. Furthermore, the waste debris after burr removal is not effectively collected and disposed of, resulting in severe dust pollution in the steel strip production environment and affecting the physical and mental health of the operators.

[0015] Example 1

[0016] The attached figure shows a specific embodiment of this utility model, such as... Figure 1-3As shown. The entire device mainly includes a housing and a grinding mechanism 2 inside the housing 1. Since the grinding mechanism 2 generates a significant amount of dust and debris during the removal of burrs from the steel strip, affecting the production environment and the health of operators, this embodiment includes a dust and debris collection structure at the bottom of the housing 1. This structure mainly includes a collection hood 3 and an airflow pipe 4. The collection hood 3 has a top-heavy design, with a smooth transition from the bottom of the housing 1 to the airflow pipe 4. The collection hood 3 and the bottom of the housing 1 can be fixed together by welding. A rigid, transparent rubber connecting pipe is provided between the collection hood 3 and the airflow pipe 4. The diameters of both the collection hood 3 and the airflow pipe 4 are slightly smaller than the connecting pipe. Both the collection hood 3 and the airflow pipe 4 are fixed to the connecting pipe by insertion. The other end of the connecting pipe is connected to an air pump. A filter screen 5 is installed at the inlet end of the airflow pipe 4. The filter screen 5 has a size of 0.1-0.5mm and is preferably made of stainless steel mesh. The diameter of the stainless steel mesh is slightly smaller than that of the airflow pipe 4. A ring-shaped limiting plate is welded to the inner wall of the airflow pipe 4 where the filter screen 5 is installed to prevent the filter screen 5 from being sucked into the airflow pipe 4 by negative pressure. The grinding mechanism 2 includes a frame, which is used to connect the grinding mechanism 2 to the housing 1. The connection method can be welding or bolting. Figure 2 The diagram shows a bolted connection. A fixing bracket can be installed inside the housing 1 as needed. Corresponding slots are provided on the fixing bracket and connecting plate 6. The fixing bracket and connecting plate 6 are connected by bolts, or the vertical position of the connecting plate 6 can be adjusted. The upper base plate of the connecting plate 6 is divided into two parts, designated as the first base plate 71 and the second base plate 72. A gap is provided between the first base plate 71 and the second base plate 72 for the steel strip 14 to pass through. L-shaped plates 8 are welded to both the first base plate 71 and the second base plate 72. Threaded holes are provided on both the L-shaped plates 8 and the cutting block 9. Two rotating screws pass through the threaded holes on the L-shaped plates 8 and the cutting block 9, respectively, to fix and adjust the height of the cutting block 9. By adjusting the distance between the first base plate 71 and the second base plate 72 and adjusting the vertical position of the cutting block 9, burr removal operations on steel strips of different thicknesses or widths can be achieved.

[0017] For ease of installation and maintenance, a viewing window 11 is provided on the side of the housing 1. The viewing window 11 is relatively large and is provided on both sides of the housing 1, facilitating the adjustment of various components of the grinding mechanism inside the housing 1. The viewing window 11 is hinged to the side wall of the housing 1, and a handle 12 is provided on the viewing window 11. To facilitate the control and adjustment of the up and down position of the steel strip 14, a guide plate 15 is provided at the front end of the connecting plate 6. One end of the guide plate 15 is welded to the connecting plate 6, and the upper part of the other end is U-shaped. A rotating shaft is provided in the middle of the steel strip guide roller 13. The rotating shaft is connected to the steel strip guide roller 13 through a bearing. The outer wall of the bearing is fixed to the steel strip guide roller 13, and the inner wall of the bearing is fixed to the rotating shaft.
