Description

Technical Field

[0001] This utility model relates to the field of galvanized steel sheet technology, and in particular to a cutting tool for galvanized steel sheets. Background Technology

[0002] Galvanized steel sheet is produced by coating the surface of steel sheet with a layer of zinc to improve its corrosion resistance. The zinc layer forms a dense protective film on the steel sheet surface, effectively blocking oxygen and moisture in the air from contacting the steel substrate, thereby slowing down the rusting rate. Depending on the galvanizing process, galvanized steel sheet can be divided into hot-dip galvanized steel sheet, electro-galvanized steel sheet, and thermal spray galvanized steel sheet. Among them, hot-dip galvanized steel sheet is the most widely used due to its thick zinc layer and excellent corrosion resistance. However, as the application of galvanized steel sheet in various industries continues to deepen, the demand for its cutting and processing is increasing, and the requirements for cutting quality and efficiency are also becoming higher.

[0003] Traditional cutting fixtures often employ simple mechanical clamping structures, which are effective for cutting most galvanized steel sheets. However, for irregularly shaped galvanized steel sheets, inaccurate clamping causes the sheet to shift during cutting. Furthermore, the large amount of iron filings generated during cutting cannot be properly handled, leading to tooling corrosion and shortening equipment lifespan. Additionally, zinc fumes are produced during cutting, posing a health hazard to operators. While cryogenic cutting technology, using water jet cutting to replace traditional laser and plasma cutting, has been introduced, utilizing the kinetic energy of high-pressure water jets to separate the sheet material and avoid high-temperature zinc vaporization, it still lacks a robust fixing structure. This results in inaccurate cutting of special galvanized steel sheets, increasing costs, and the inability to collect and handle iron filings during cutting, impacting work efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a galvanized steel plate cutting tool, which aims to improve the problems in the prior art where it is impossible to cut special galvanized steel plates accurately and the iron filings generated during cutting cannot be collected and processed.

[0040] Working principle: First, the galvanized steel sheet is placed in the fixing groove 3. Since the inner wall of the fixing groove 3 is connected to the support plate 4, and multiple buffer pads 5 are connected to the support plate 4, springs 6 are installed on the buffer pads 5, and the other end of the springs 6 is connected to the flexible column 7. When the galvanized steel sheet is placed on the fixing groove 3, since the multiple flexible columns 7 are higher than the fixing groove 3, the galvanized steel sheet first contacts the multiple flexible columns 7, and the flexible columns 7 are lowered by gravity. At this time, the screw 10 is rotated, and the flexible column 7 is fixed by the fixing block 8 and the corrugated plate 9 on the screw 10, so that the galvanized steel sheet is placed stably on the flexible column 7. After processing, simply rotate the screw 10 in the opposite direction to reset the flexible column 7 with the elastic force of the bottom spring 6, and the galvanized steel sheet can be removed. The characteristics of the flexible column 7 make it possible to place irregular galvanized steel sheets stably without changing the plane, so that the placement is stable during processing and the processing efficiency is improved.

[0041] During processing, the support plate 4 has multiple grooves 208 on its top, allowing the iron filings generated during processing to enter the worktable 1. At this time, the motor 201 is started, and the rotation of the motor 201 drives the rotating shaft 207 to rotate, which in turn causes the gears 203 on the rotating shaft 207 to rotate, thereby driving the moving plate 204, which meshes with the multiple gears 203, to rotate. The falling iron filings enter the collection groove 205 on the moving plate 204, and then the collection groove 205 transports them to the collection box 206. With the help of gravity, the iron filings slide down into the collection box 206, completing the collection.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
