DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1 - Figure 4 , a cold rolling mill for stainless steel production, comprising a fixed pressure roller 2 installed on a base 1 and a movable pressure roller 4 installed on a top plate 3, wherein a guide platform 5 is fixedly connected to a side of the base 1 close to the top plate 3, and the guide platform 5 is located on one side of the discharge end of the fixed pressure roller 2, and a cutting structure is arranged directly above the guide platform 5, and the cutting structure comprises two synchronous hydraulic rods 6, both of which are fixedly connected to the top plate 3, and the ends of the two synchronous hydraulic rods 6 away from the top plate 3 are output ends, and the output ends of the two synchronous hydraulic rods 6 are fixedly connected to connecting blocks 7, and a mounting rod 8 is rotatably connected between the two connecting blocks 7, and a cutting motor 17 is fixedly connected to a side of one connecting block 7 away from the mounting rod 8, and the output shaft of the cutting motor 17 passes through the connecting block 7 and is fixedly connected to the mounting rod 8, and two cutting blades 9 are sleeved and slidably connected to the outer wall of the mounting rod 8, and a mounting assembly is connected between the two cutting blades 9 and the mounting rod 8, and a plurality of cutting grooves 501 are arranged on a side of the guide platform 5 close to the two cutting blades 9.

[0023] like Figure 1 - Figure 4 As shown, the cold rolling mill for stainless steel production in the utility model is similar to the existing cold rolling mill for stainless steel production, such as a high-gloss stainless steel strip cold rolling mill disclosed in the patent with publication number CN218656138U. The main improvement of the utility model is that the edges of both sides of the thin stainless steel can be cut flat during cold rolling, reducing the reprocessing process of the thin stainless steel and improving the production and processing efficiency of the stainless steel. Figures 1 to 4 As shown, when the cold rolling mill for stainless steel production in the utility model is in use, when the thick stainless steel plate enters between the fixed pressure roller 2 and the movable pressure roller 4 for cold rolling, the thin stainless steel after cold rolling pressing enters the guide table 5 and is cut by the two cutting blades 9 above the guide table 5, so that the edges on both sides of the pressed thin stainless steel are cut flat, so that the thin stainless steel finally guided out from the outlet of the cold rolling mill can be rolled up, and it is no longer necessary to cut the edges again, thereby reducing the cold rolling process of the stainless steel and improving the production and processing efficiency of the stainless steel. The two synchronous hydraulic rods 6 can be adjusted according to the actual thickness of the thin stainless steel after pressing, so that the cutting blades 9 can perform better cutting operations. At the same time, by starting the cutting motor 17 to drive the mounting rod 8 to rotate, the two cutting blades 9 can rotate and cut, avoiding obstruction of the cutting of the thin stainless steel, and cooperating with the cutting groove 501, it can complete the cutting of the thin stainless steel while reducing the possibility of cutting curling or cutting burrs on the edge of the stainless steel, further improving the cutting effect.

[0024] like Figure 2 - Figure 4As shown, the mounting assembly includes a connecting plate 10 and a mounting block 11. The connecting plate 10 is sleeved with the mounting rod 8 and fixedly connected to one side of the cutting blade 9. The side of the connecting plate 10 away from the cutting blade 9 and close to the mounting rod 8 is fixedly connected to the mounting block 11. The end of the mounting block 11 away from the mounting rod 8 is threadedly connected with a fastening bolt 12. The threaded rod of the fastening bolt 12 passes through the mounting block 11 and abuts against the mounting rod 8. After the cutting blade 9 is mounted on the mounting rod 8, the connection plate 10 can be used to further strengthen the firmness of the cutting blade 9 when cutting and being stressed, so as to avoid the cutting blade 9 from bending. At the same time, when the cutting motor 17 drives the cutting blade 9 to rotate and cut, the fastening bolt 12 fastens the mounting block 11 to the mounting rod 8, so that the cutting blade 9 is not easy to slip on the mounting rod 8, so that the cutting blade 9 can smoothly perform rotational cutting.

[0025] like Figure 2 - Figure 4 As shown, the outer wall of the mounting rod 8 is provided with a limiting groove 801, and the threaded rod of the fastening bolt 12 passes through the mounting block 11 and abuts against the inner wall of the limiting groove 801. By providing the limiting groove 801 on the mounting rod 8 and abutting the fastening bolt 12 in the limiting groove 801, when the cutting motor 17 drives the cutting blade 9 to rotate and cut, the cutting blade 9 can perform rotational cutting stably without rotational slippage, thereby ensuring smooth rotational cutting.

[0026] like Figure 1 - Figure 4 As shown, the cutting blade 9 is fixedly connected to the connecting plate 10 by screws and nuts. The connecting plate 10 is fixedly installed by screws and nuts, so that the cutting blade 9 can be replaced when the cutting effect of the cutting blade 9 decreases. This connection method is similar to the connection method of the cutting disc of the existing angle grinder.

[0027] like Figure 2 and Figure 3 As shown, a material dividing groove 502 is provided on the side of the guide platform 5 away from the base 1, and the material dividing groove 502 is located on the side of the cutting groove 501 away from the fixed pressure roller 2. A material dividing mechanism is connected in the material dividing groove 502, and a material guide groove 503 is provided on the side of the material dividing groove 502 away from the fixed pressure roller 2. After the cutting blade 9 has completed cutting the two side edges of the pressed thin stainless steel, the two side edges cut can be separated from the finished stainless steel in the middle through the two material dividing mechanisms, so that the finished stainless steel is guided out of the cold rolling mill through the material guide groove 503 for winding operation, thereby preventing the cut scraps from affecting the winding of the finished stainless steel in the middle.

[0028] like Figure 2 and Figure 3As shown, the material dividing mechanism includes two material dividing plates 13, the two material dividing plates 13 are rectangular structures, and the two material dividing plates 13 are designed with curved surfaces on one end close to the cutting blade 9 and the side away from each other. The two material dividing plates 13 are perpendicular to the material dividing groove 502 and extend upward from the material dividing groove 502 to a certain height, and an adjustment component is connected between the two material dividing plates 13. The two material dividing plates 13 guide the cut scraps to the two sides of the cold rolling mill through the curved surface to avoid the cut scraps from mixing with the finished stainless steel in the middle. The adjustment component can adjust the distance between the two material dividing plates 13, so that the material dividing plates 13 can be suitable for stainless steel pressing operations of various different widths.

[0029] like Figure 2 and Figure 3 As shown, the adjustment component includes a positioning slide 14, a bidirectional screw rod 15 and an adjustment motor 16. The positioning slide 14 and the bidirectional screw rod 15 are both located in the material dividing trough 502 and are lower than the upper surface of the material guiding trough 503. The two ends of the positioning slide 14 respectively penetrate the two material dividing plates 13 and are respectively fixedly connected to the inner walls on both sides of the material dividing trough 502. The positioning slide 14 and the two material dividing plates 13 are both slidingly connected. The two ends of the bidirectional screw rod 15 respectively penetrate the two material dividing plates 13 and are respectively rotatably connected to the inner walls on both sides of the material dividing trough 502, and the bidirectional screw rod 15 and the two material dividing plates 13 are both threadedly connected. The outer wall of the adjustment motor 16 is fixedly connected to the outer wall of the material guiding platform 5 through a connecting seat. The output end of the adjustment motor 16 penetrates the material guiding platform 5 and is fixedly connected to one end of the bidirectional screw rod 15. When the dividing plates 13 are used to guide the dividing of the cut stainless steel, the bidirectional screw rod 15 is driven to rotate by adjusting the motor 16, so that the two dividing plates 13 can be close to or away from each other, so that the two dividing plates 13 can be suitable for cutting stainless steel of different widths. At the same time, when the two dividing plates 13 are moved and adjusted, the positioning slide bar 14 can prevent the two dividing plates 13 from tilting, thereby improving the stability of the connecting structure of the dividing plates 13.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
