[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a hot rolling apparatus for producing die steel. (See also...) Figure 1 and Figure 5 A hot rolling device for producing mold steel includes a connecting plate 1, a processing box 3 fixedly connected to the top of the connecting plate 1, multiple sets of rollers 7 arranged inside the processing box 3, a spray assembly 2 arranged on the top of the processing box 3, and a filter assembly 9 fixedly connected to the bottom of the connecting plate 1.

[0019] The filter assembly 9 includes a storage box 91, which is fixedly connected to the bottom of the connecting plate 1. A positioning plate 94 is provided inside the storage box 91. A hinge 95 is hinged to the surface of the positioning plate 94. A handle 96 is fixedly connected to the surface of the positioning plate 94. Filter plates 93 are fixedly connected to both sides of the positioning plate 94.

[0020] The connecting plate 1 facilitates the connection of the entire equipment. Then, under the action of the processing box 3, the roller 7 can process the steel. Afterwards, the pickling solution can be sprayed through the spray assembly 2. When the pickling waste liquid flows into the storage box 91, it will be initially filtered by the filter plate 93 and stored in the storage box 91 for subsequent centralized processing. When the filter plate 93 needs to be filtered, the positioning plate 94 can be flipped down by the handle 96 (using the mobility of the hinge 95) so that the filter plate 93 tilts downward for easy replacement.

[0021] Reference Figure 1 and Figure 5The spray assembly 2 includes a water pump 21. The input end of the water pump 21 is connected to a water tank 22, and the output end of the water pump 21 is connected to a water pipe 27. One end of the water pipe 27 is connected to a liquid box 23, and the bottom end of the liquid box 23 is connected to a nozzle 25. By using the water pump 21, the pickling solution inside the water tank 22 can be extracted and transported to the liquid box 23 for storage through the water pipe 27. The solution can be sprayed out through the nozzle 25 to remove the iron oxide scale from the surface of the steel.

[0022] Reference Figure 1 and Figure 5 The top of the liquid box 23 is connected to a fixing block 24, which is fixedly connected to the top of the inside of the processing box 3. The fixing block 24 uses a locking structure (such as a slot and a protrusion) to firmly fix the liquid box 23 in a preset position at the top of the processing box 3, so as to prevent the liquid box 23 from shifting due to pressure fluctuations or equipment vibration when the water pump 21 delivers the medium. This ensures that the nozzle 25 is always aligned with the rolling area of ​​the roll 7 and the billet, and that the spray range of multiple nozzles 25 evenly covers the target area, avoiding local insufficient cooling, uneven lubrication or impurity residue due to positional deviation.

[0023] Reference Figure 1 and Figure 5 A strainer plate 6 is fixedly connected to the surface of the connecting plate 1. A load-bearing shaft 101 is fixedly connected to the bottom periphery of the connecting plate 1. The aperture of the strainer plate 6 is larger than that of the filter plate 93 but smaller than large pieces of iron oxide scale or metal shavings. It can intercept larger impurities generated during the rolling process in advance, prevent them from directly entering the filter assembly 9 and causing blockage, reduce the burden on the subsequent filter plate 93, and extend the maintenance cycle of the filter assembly 9.

[0024] Reference Figure 1 and Figure 5 Multiple sets of rolls 7 are equipped with disassembly components 5 at both ends. The disassembly components 5 include L-shaped connecting plates 51. A support block 52 is fixedly connected to the top of the L-shaped connecting plates 51. A limit ring 53 is fixedly connected to the top of the support block 52. A bolt 54 passes through the top of the limit ring 53. Nuts 55 are threaded on both ends of the bolt 54. When it is necessary to replace or repair the rolls 7, the size inside the limit ring 53 can be adjusted by loosening the nuts 55. When the limit ring 53 is adjusted to the preset position, it is easy to remove the rolls 7 for replacement or repair.

[0025] Reference Figure 1 and Figure 5 The inner wall of the storage box 91 is fixedly connected to a locking plate 92, and the filter plate 93 is locked onto the surface of the locking plate 92. The locking plate 92 facilitates the placement of the filter plate 93, keeping it in a horizontal state, which is convenient for subsequent filtration operations.

[0026] Reference Figure 1 and Figure 5A rubber sealing ring 26 is provided at the junction of the water pipe 27 and the processing box 3. A fixing plate 8 is fixedly connected to the top of the multiple sets of rollers 7. The rubber sealing ring 26 fills the gap between the water pipe 27 and the processing box 3 with its own elasticity. It forms a tight sealing surface through compression deformation to prevent the medium from seeping out from the junction, ensuring the pressure stability and medium utilization rate of the spray assembly 2. The fixing plate 8 can be used to install and fix it to prevent it from falling off and damaging the equipment during use.

[0027] Working principle: The connecting plate 1 facilitates the connection of the entire equipment. Then, the processing box 3 facilitates the installation of the rollers 7. The rotating rollers 7 apply pressure to the high-temperature billet, causing it to plastically flow and ultimately form a product with a specific cross-section. Afterwards, the pickling solution is sprayed through the spray assembly 2. When the pickling waste liquid flows into the storage box 91, it undergoes preliminary filtration through the filter plate 93 and is stored inside the storage box 91 for subsequent centralized processing. When filtration through the filter plate 93 is needed, it can be removed by using the handle 9. 6. Flip the positioning plate 94 (using the mobility of the hinge 95) so that the filter plate 93 tilts downward for easy replacement. The pickling solution inside the water tank 22 can be extracted by the water pump 21 and transported to the liquid box 23 for storage through the water pipe 27. The solution can be sprayed out through the nozzle 25 to remove the iron oxide scale from the surface of the steel. When the roll 7 needs to be replaced or repaired, the size of the limit ring 53 can be adjusted by loosening the nut 55. When the limit ring 53 is adjusted to the preset position, the roll 7 can be taken out for replacement or repair.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
