[0002] In the production of forgings, it is usually necessary to heat the target material to the forging temperature. Since a relatively thick oxide scale will be generated on the surface of the target material at this temperature, the oxide scale on the surface of the target material needs to be cleaned before the target material enters the mold. At present, in the field of metal material surface oxide scale cleaning technology, the existing equipment generally adopts a metal mesh belt conveyor structure, which carries and transports the material to the cleaning station through a mesh conveyor belt, and cleans the oxide scale by mechanical brushing or high-pressure water spraying. It has certain flexibility and applicability under light load conditions; however, when handling heavy When conveying metal materials (rods), the metal mesh belt is prone to flexural deformation due to its own lack of rigidity, resulting in local depression or mesh expansion, which not only causes deviation and jamming during material transportation, but also forms cleaning dead corners due to the uneven contact surface between the mesh belt and the material, making it impossible for high-pressure cleaning media (such as water jets) to evenly cover the material surface, significantly reducing the efficiency of oxide scale removal; in addition, the long-term deformation of the metal mesh belt will aggravate stress concentration and accelerate structural fatigue damage, requiring frequent shutdown for maintenance or replacement of the mesh belt, further increasing the operating cost of the equipment and limiting its application in heavy workpiece cleaning scenarios.

In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0022] Please also read Figures 1 to 4, a roller type oxide skin cleaning machine provided in an embodiment of the present application is now described. The roller type oxide skin cleaning machine includes a main frame 101, a conveying roller 102, a cleaning assembly and a driving mechanism. Among them, a plurality of conveying rollers 102 are arranged side by side at intervals on the main frame 101, and the middle part of the conveying roller 102 forms a first cone section 103 and a second cone section 104 coaxial with itself, and the small ends of the first cone section 103 and the second cone section 104 are opposite to each other and form a V-shaped annular groove space for conveying the target material 200; the cleaning assembly includes a plurality of nozzles 105 and a liquid supply device connected to the nozzle 105, and the plurality of nozzles 105 are arranged at intervals along the axial direction of the conveying roller 102 and are aligned with the conveying roller 102 in the axial direction of the conveying roller 102. The liquid spraying port of the nozzle 105 faces the conveying roller 102 and is used to spray high-pressure liquid; the driving mechanism is connected to the conveying roller 102 and is used to drive the conveying roller 102 to rotate. In the present application, the driving mechanism may be a commonly used driving mechanism in the art, and the connection and installation between the conveying roller 102 and the main frame may also adopt the existing technology, which will not be described in detail here.

[0023] According to the above structure provided in the present embodiment, in the roller type oxide skin cleaning machine provided in the present embodiment, a plurality of conveying rollers 102 arranged side by side are used to convey the target material 200. When the target material 200 is conveyed to pass through the cleaning assembly, the nozzle 105 connected to the liquid supply device in the cleaning assembly can clean the oxide skin on the surface of the target material 200 by spraying high-pressure liquid. Since the conveying roller 102 itself has a very strong workpiece load capacity, and since the central part of the conveying roller 102 also forms a conical first cone section 103 and a second cone section 104, when the target material 200 is accommodated in the V-shaped annular groove space between the first cone section 103 and the second cone section 104, it can not only be stably moved forward under the drive of the conveying roller 102, but also even a heavy workpiece can be stably conveyed, which significantly improves the oxide skin cleaning efficiency of the roller type oxide skin cleaning machine in the present embodiment for heavy workpieces, which is far superior to the prior art.

[0024] Here, it can be understood that the liquid supply device usually includes a high-pressure water pump and corresponding pipelines for pressurizing liquid (the liquid used in this embodiment is water). The water inlet end of the high-pressure water pump is connected to the water tank 122 (described later) through a pipeline, and the water outlet end of the high-pressure water pump is connected to the nozzle 105 through a pipeline, so that the water in the water tank 122 is sucked and pressurized to a set pressure and sprayed from the nozzle 105 to the surface of the target material 200, and the oxide scale is removed by using the pressure and temperature effects of water. The existing technology is used for the installation and fixation of the nozzle 105 and the connection with the high-pressure water pump and the pipeline.

[0025] In another embodiment of the present application, please refer to Figures 1 to 4A rib 106 is raised on the surface of the first cone section 103 , and the cross section of the rib 106 is an arc shape; the rib 106 extends from the large end to the small end of the first cone section 103 and is evenly arranged around the central axis of the first cone section 103 . According to the above structure provided in the present embodiment, the ribs 106 arranged on the first cone section 103 can, on the one hand, make it easier for the target material 200 to move forward when the conveying roller 102 rotates, and on the other hand, can effectively avoid the formation of too much water accumulation contact surface between the conveying roller 102 and the target material 200. Moreover, since the ribs 106 are evenly distributed on the surface of the first cone section 103, there are intervals between the ribs 106, so that intermittent contact with the surface of the target material 200 is formed during the rotation of the conveying roller 102, thereby generating low-amplitude vibration, which has the effect of vibrating and loosening the oxide scale attached to the surface of the target material 200. It can be understood that the vibration frequency is related to the rotation speed of the conveying roller and the interval between the ribs 106; this can not only significantly improve the oxide scale cleaning effect of the target material 200, but also help to further improve the oxide scale cleaning efficiency of the roller-type oxide scale cleaning machine in the present embodiment.

[0026] In another embodiment of the present application, please refer to Figures 1 to 4, the surface of the second cone section 104 forms a spiral strip 107 coaxial with the second cone section 104, wherein the cross section of the spiral strip 107 is a triangle. According to the above structure provided in this embodiment, the spiral strip 107 coaxial with the second cone section 104 and arranged on the second cone section 104 can exert a tangential force perpendicular to the radial direction on the outer cylindrical surface of the target material 200 (the principle is that the target material 200 has its own weight, and its surface forms an optical axis and a spiral pair after contacting with the spiral strip 107, so that when the conveying roller 102 rotates, since the axial position of the conveying roller 102 itself is fixed, the spiral strip 107 will generate a tangential force perpendicular to the radial direction of the target material 200 on the outer cylindrical surface of the target material 200 when rotating with the conveying roller 102), so that the target material 200 generates a rotational torque relative to its own axial direction, so that the target material 200 can also rotate around its own central axis during the forward process, In this way, on the one hand, the triangular cross-section tip of the spiral strip 107 has a mechanical scraping effect on the oxide scale on the surface of the target material 200. On the other hand, the contact between the target material 200 and the conveying roller 102 is always in dynamic change, avoiding long-term contact between the target material 200 and the conveying roller at the same position to cause local cooling, which significantly improves the temperature uniformity of the target material 200. In addition, when the target material 200 passes through the nozzle 105 area, the high-pressure water jet sprayed by the nozzle 105 can cover the surface of the target material 200 without dead angles, which not only significantly improves the oxide scale cleaning effect of the target material 200, but also ensures the surface temperature uniformity of the target material 200, further improving the oxide scale cleaning quality and efficiency of the roller-type oxide scale cleaning machine in this embodiment. In addition, in the aforementioned embodiment in which the ribs 106 are provided, the ribs 106 can reduce the friction force when the target material 200 rotates around its own central axis under the action of the spiral bars 107 (at this time, the ribs 106 have a greater driving force relative to the forward direction of the target object 200, and the target material 200 is more easily pushed forward), thereby utilizing the ribs 106 to help the target material 200 rotate easily, which is beneficial to further improve the oxide scale cleaning efficiency and cleaning quality of the roller-type oxide scale cleaning machine in this embodiment.

[0027] In another embodiment of the present application, please refer to Figures 1 to 4 , multiple conveying rollers 102 are arranged obliquely relative to the horizontal direction of the path of the target material 200; the roller type oxide skin cleaning machine also includes a loading platform 108 and a receiving platform 109, the loading platform 108 is close to the highest conveying roller 102 and has a roller 110 for conveying the target material 200, and the receiving platform 109 is close to the lowest conveying roller 102 and has a top plate 111 for receiving the target material 200. For the convenience of description, this embodiment is described by taking the angle a=2° formed between the arrangement direction of the multiple conveying rollers 102 and the horizontal direction as an example.

[0028] According to the above structure provided in the present embodiment, the multiple conveying rollers 102 arranged obliquely can significantly improve the conveying efficiency of the target material 200; in addition, the loading platform 108 and the receiving platform 109 provided in conjunction with the conveying rollers 102 can make it easier for the target material 200 after the heating treatment to be transferred from the drum 110 to the conveying roller 102 or from the conveying roller 102 to the receiving platform 109, which is beneficial for the operator to perform the matching operations before and after the oxide scale cleaning, and is also beneficial for further improving the oxide scale cleaning efficiency of the roller type oxide scale cleaning machine in the present embodiment; the angle a is set to 2°, and its technical effect is that, on the one hand, the target material 200 will not slide out along the conveying channel formed by the conveying rollers 102, and its moving speed is completely controlled by the conveying rollers 102, which is beneficial for controlling the moving speed of the target material 200 through a driving mechanism (such as using a servo or variable frequency motor as a power source), thereby ensuring the quality and efficiency of the oxide scale cleaning; on the other hand, it can ensure that the target material 200 entering the area of ​​the conveying roller 102 will not return to the loading platform 108, thereby ensuring the safety of the equipment and the operating staff.

[0029] In another embodiment of the present application, please refer to Figures 1 to 4 The receiving platform 109 further includes a turntable 112 rotatably mounted on the top plate 111, a rotation shaft 113 coaxially connected to the turntable 112, and a handle 114 connected to the rotation shaft 113; the turntable 112 is flush with the top plate 111, the rotation shaft 113 is perpendicular to the top plate 111, and the handle 114 extends along the radial direction of the rotation shaft 113 and is used to drive the turntable 112 to rotate relative to the top plate 111 through the rotation shaft 113. According to the above structure provided in this embodiment, the target material 200 after the oxide scale is cleaned can be transferred to the top plate 111 and provided for subsequent tool grabbing and transfer. Since the turntable 112 can rotate relative to the top plate 111 and is flush with the top plate 111, the operator can drive the turntable 112 to rotate through the handle 114 and the shaft 113 in advance, so as to adjust the target material 200 on the top plate 111 to a predetermined posture, which can facilitate the subsequent transfer operation of the target material 200, and is also conducive to further improving the oxide scale cleaning efficiency of the roller type oxide scale cleaning machine in this embodiment.

[0030] In another embodiment of the present application, please refer to Figures 1 to 4The receiving platform 109 further includes a chute 115 which is arranged obliquely relative to the horizontal direction; the chute 115 is arranged between the conveying roller 102 and the top plate 111, and the lower end of the chute 115 is smoothly connected to the top plate 111. According to the above structure provided in this embodiment, the chute 115 arranged between the conveying roller 102 and the top plate 111 can make the target material 200 transfer from the conveying roller 102 to the top plate 111 more smoothly, which is conducive to further improving the oxide scale cleaning efficiency of the roller type oxide scale cleaning machine in this embodiment.

[0031] In another embodiment of the present application, please refer to Figures 1 to 4 The receiving platform 109 further includes a plurality of retaining edges 116; the retaining edges 116 are connected to the top plate 111 and are used to limit the target material 200 from falling from the top plate 111. According to the above structure provided in this embodiment, the retaining edges 116 connected to the top plate 111 can, on the one hand, play a good protective effect by limiting the target material 200 from falling from the top plate 111, and on the other hand, can also make the target material 200 fall more accurately to contact with the turntable 112, so that the turntable 112 can adjust its posture, which is conducive to further improving the oxide scale cleaning efficiency of the roller type oxide scale cleaning machine in this embodiment.

[0032] In another embodiment of the present application, please refer to Figures 1 to 4 The roller type oxide skin cleaning machine also includes a first shield 117 connected to the main frame 101; all the conveying rollers 102 are arranged inside the first shield 117, and door panels 118 are formed on opposite sides of the first shield 117 to enable the target material 200 to enter the first shield 117 from the loading platform 108 in one direction or be transferred from the inside of the first shield 117 to the receiving platform 109 in one direction, and the nozzle 105 penetrates the first shield 117 and extends into the inside of the first shield 117. According to the above structure provided in this embodiment, the first shield 117 connected to the main frame 101 can effectively prevent the oxide skin from splashing during the oxide skin cleaning process on the target material 200, which is conducive to significantly improving the safety protection effect of the roller type oxide skin cleaning machine in the embodiment.
