If the guide of the above patent is used for cutting, the iron filings will clog the cutting groove, and the iron filings remaining in the cutting groove will scratch the surface of the large steel. Summary of the invention

[0005] The purpose of the utility model is to solve the problem in the prior art that due to the large width of large steel materials, more wires need to be cut, so a large amount of iron filings and sparks will be generated during the cutting process. If the five-cut rolling guide of the bar material of the above patent is used for cutting, the iron filings will block the cutting groove, and the iron filings remaining in the cutting groove will scratch the surface of the large steel material. The high-precision cutting guide for large steel materials is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-precision cutting guide for large steel materials, including a cutting box, an eccentric shaft is symmetrically rotatably clamped on the inner side of the cutting box, and cutting wheels are evenly installed on the outer sides of several eccentric shafts, both sides of the inner wall of the cutting box are fixedly connected to drive rails, and a cleaning plate is movably clamped on the outer side of the drive rails, and both ends of the cleaning plate are fixedly connected to a No. 1 gear, the outer side of the No. 1 gear is meshed with a rack, and the other end of the inner side of the rack is meshed with a No. 2 gear, and one side of the No. 2 gear is transmission-connected to a drive assembly.

[0027] The following is a detailed description of the specific settings and functions of this embodiment. After the cutting operation of the large steel is completed, the driving component 23 is started, driving the No. 2 gear 22 to rotate, the No. 2 gear 22 and the rack 21 are meshed with each other, and the rack 21 drives the No. 1 gear 31 to rotate, so that the No. 1 gear 31 drives the cleaning plate 3 to slide inside the cutting box 1, and the iron filings accumulated inside the cutting box 1 are swept out, thereby avoiding the situation where the iron filings block the cutting groove and the iron filings remaining in the cutting groove scratch the surface of the large steel. The swept iron filings slide into the iron filing collection box 12 under the action of gravity, avoiding the iron filings from being scattered randomly on both sides of the large steel high-precision cutting guide. Workers regularly clean and recycle the iron filings accumulated in the iron filing collection box 12 to improve the utilization rate of large steel raw materials.

[0028] Embodiment 2: Figure 1 and Figure 5 As shown, both ends of one side of the driving track 2 are fixedly connected with the baffle track 25, both sides of the cleaning plate 3 are fixedly connected with the iron chip baffle 32, the iron chip baffle 32 is movably connected to the inner side of the baffle track 25, both ends of the outer side of the cleaning plate 3 are fixedly connected with the iron chip brush 33, and both ends of the inner side of the cleaning plate 3 are fixedly connected with the flexible brush 34.

[0029] The effect achieved by the entire embodiment is that when the cleaning plate 3 slides, the iron chip baffle 32 blocks the groove of the drive track 2, preventing the cleaning plate 3 from cleaning the iron chips into the interior of the drive track 2, affecting the transmission of the rack 21 to the first gear 31 and the second gear 22, thereby improving the stability of the large steel high-precision cutting guide in cleaning the iron chips. In addition, since flexible brushes 34 are fixedly connected to the two ends of the inner side of the cleaning plate 3, when the large steel passes through the cleaning plate 3 and enters the interior of the large steel high-precision cutting guide, the flexible brush 34 cleans the surface of the large steel, preventing debris from adhering to the surface of the large steel and affecting the accuracy of the large steel high-precision cutting guide for high-precision cutting of the large steel.

[0030] The use method and working principle of the device: After the large steel material is cut, the driving assembly 23 is started, driving the second gear 22 to rotate, the second gear 22 and the rack 21 are meshed with each other, and the rack 21 drives the first gear 31 to rotate, so that the first gear 31 drives the cleaning plate 3 to slide inside the cutting box 1, and the iron filings accumulated inside the cutting box 1 are cleaned out. The cleaned iron filings slide into the iron filing collection box 12 under the action of gravity, so as to prevent the iron filings from being randomly scattered on the two sides of the large steel material high-precision cutting guide. On the other hand, when the cleaning plate 3 slides, the iron chip baffle 32 blocks the groove of the driving track 2, preventing the cleaning plate 3 from cleaning the iron chips into the interior of the driving track 2, affecting the transmission of the rack 21 to the first gear 31 and the second gear 22, thereby improving the stability of the large steel high-precision cutting guide in cleaning the iron chips. In addition, since flexible brushes 34 are fixedly connected to the two ends of the inner side of the cleaning plate 3, when the large steel passes through the cleaning plate 3 and enters the interior of the large steel high-precision cutting guide, the flexible brushes 34 clean the surface of the large steel.
