Description

Technical Field

[0001] The utility model belongs to the technical field of welded pipe processing, in particular to a welded pipe cutting device. Background Art

[0002] Welded pipe is the abbreviation of welded steel pipe. Welded pipe refers to a pipe made by cutting steel plates or steel strips into a certain length through welding process, and then rolling, cold bending, high-frequency welding and other processes. It uses the processing and connection technology of steel plates or steel strips to produce various types of steel pipes. Welded pipes are widely used in construction, bridges, roads, tunnels, pipelines, machinery, chemical equipment, automobile industry and other fields.

[0032] Specifically, two scale plates 112 are provided on the surface of the workbench 1, and the scale plates 112 are respectively located on both sides of the slide groove 111. The bottom of the workbench 1 is supported by a bracket 113. The positioning plate 150 can move inside the slide groove 111 according to the required length, and the value is determined by the scale plates 112.

[0033] Furthermore, a support plate 122 is connected to the top of the moving platform 120 , a circular groove is provided inside the support plate 122 , a stud 123 is connected to the top of the support plate 122 , and the stud 123 passes through the top of the support plate 122 and is connected to a top plate 124 inside the circular groove.

After the cutting is completed, remove the end connected to the positioning plate 150, and move the movable table 120 along the slide rail 110 under the action of the slider 121, and fix the cut end to the positioning plate 150, and then start a new round of cutting. In this process, there is no need to remove both ends of the welding pipe body 160 for re-fixing, which saves working time. Specific embodiment 2

[0036] See also Figure 3 and Figure 4 On the basis of the first specific embodiment, a collection box 140 is connected to the inner center of the workbench 1, and the collection box 140 is located directly below the cutting frame 130. A slot is provided on the bottom side of the collection box 140, and a storage box 142 is connected to the bottom slot of the collection box 140. Incisions 141 are provided on both sides of the top of the collection box 140.

Most of the debris generated during cutting can fall into the storage box 142 inside the collection box 140, so as to avoid the debris being concentrated on the workbench 1 or falling on the ground and being inconvenient to clean up. After the storage box 142 collects to a certain extent, the storage box 142 can be taken out to clean up the debris inside. Specific embodiment three

[0041] See also Figure 4-Figure 6On the basis of the first and second specific embodiments, a truncated cone 151 is connected to the side of the positioning plate 150 facing the cutting frame 130, a connecting plate 152 is connected to the bottom of the positioning plate 150, a moving block 153 is connected to the bottom of the connecting plate 152, an annular plate 154 is connected to the side of the truncated cone 151, a screw rod 156 is connected to the bottom and top center of the annular plate 154, and the screw rod 156 passes through the annular plate 154 and is connected to the outer side of the contact plate 155.

[0043] When the welding pipe body 160 is located in the same plane as the connecting plate 152 in the vertical direction, the length of the welding pipe body 160 can be determined according to the position of the connecting plate 152 on the scale plate 112, and the welding pipe body 160 can be accurately positioned, which can effectively avoid the situation of length misalignment during measurement.

[0044] The operation process of this embodiment is: when fixing, one end of the welding pipe body 160 is brought into contact with the surface of the truncated cone 151, and then the screw rod 156 is turned to drive the contact plate 155 to contact and fix the outer surface of the welding pipe body 160, and the connecting plate 152 moves in the slide groove 111 through the moving block 153. Since the welding pipe body 160, the truncated cone 151 and the connecting plate 152 are in the same plane in the vertical direction, the cutting length can be determined according to the scale line corresponding to the side of the connecting plate 152 and the scale plate 112.
