Description

Technical Field

[0001] This application relates to the field of oxide scale removal machinery technology, specifically a rotary mechanical descaling device. Background Technology

[0002] In metal forging, metal bars typically need to be heated to a set forging temperature for plastic forming. However, after heating to high temperatures, oxide scale forms on the surface of the metal bars. This oxide scale needs to be removed before the bars enter the mold to ensure the quality of the forgings. Small bars or ordinary carbon steel materials are usually treated with brushing or high-pressure water jet descaling equipment. However, for some special materials, such as stainless steel (containing chromium, nickel, etc.) and high-temperature alloys (containing cobalt, titanium, nickel, etc.), the oxide layer on the surface of titanium alloys is firmly bonded to the substrate, making it difficult to remove the surface oxide scale using brushing or high-pressure water descaling methods. These materials are usually upsetting to remove the oxide scale. However, when the bar diameter exceeds 200 mm and the length exceeds 1000 mm, upsetting is difficult and can easily cause the bar to bend and be scrapped. Therefore, it is necessary to solve the above problems. Summary of the Invention

The support 3 is used to support the target bar stock. When the support 3 descends to a set position, the target bar stock rolls into contact with roller 1 and roller 2 and disengages from the support 3. Roller 1 and / or roller 2 are used to rotate the target bar stock around its own axis. When the support 3 rises to a set position, the target bar stock disengages from roller 1 and roller 2.

[0015] Waste discharge pipe 17 is located at the bottom of the polymer bottom shell 9 and is connected to the polymer bottom shell 9;

[0018] Furthermore, a spiral protrusion 101 is provided on the outer circumference of the first roller 1, and a plurality of straight grooves 201 are evenly distributed on the outer circumference of the second roller 2, wherein the longitudinal direction of the straight grooves 201 is parallel to the axis of the second roller 2.

[0019] Furthermore, the rotary mechanical descaling device also includes:

[0020] Rotary joints 24 are respectively located at both ends of the first roller 1 and the second roller 2;

[0021] The water pump 7 is connected to the rotary joint 24 and the nozzle 6 at their respective ends via pipes, and is used to supply water from the water tank 11 to the roller 1, the roller 2, and the nozzle 6.

[0022] Furthermore, several through slots 301 are formed on the bracket 3, and the upper end of the bracket 3 is arc-shaped.

[0023] Furthermore, the rotary mechanical descaling device also includes a frame 10, wherein both roller 1 and roller 2 are rotatably supported by the frame 10; guide rails 13 are provided at both ends of the frame 10, and sliding frames 14 are respectively provided at both ends of the cover 5 and are slidably connected to the corresponding guide rails 13; the guide rails 13 are horizontally arranged and perpendicular to the axis of roller 1; the cover opening cylinder 15 is hinged to the frame 10 and its output end is connected to the sliding frame 14, for driving the cover 5 to open and close.

[0024] Furthermore, the rotary mechanical descaling device also includes:

[0025] An end cylinder 16 is mounted on the frame 10 and its output end is connected to the end scraper 4. It is used to drive the end scraper 4 away from or closer to the target bar and to make the end scraper 4 strike the end face of the target bar at a set frequency. The two end scrapers 4 have teeth on opposite sides.

[0026] The guide plate 19 is located above the polymer bottom shell 9 and is connected to the frame 10 at both ends. The bottom of the end scraper 4 is connected to the slide plate 20, and the two ends of the slide plate 20 are slidably engaged with the guide plate 19.

[0027] Furthermore, the rotary mechanical descaling device also includes a lifting rod 21, which slides vertically through the aggregate bottom shell 9, with its upper end connected to the bottom of the bracket 3 and its lower end connected to a linear drive power source to drive the bracket 3 to move up and down; a sealing seat 23 is provided on the aggregate bottom shell 9; the sealing sleeve 22 seals and connects the sealing seat 23 and the bracket 3 at both ends respectively, and seals and encloses the lifting rod 21 inside.

[0028] The beneficial effects of this application are as follows: This application provides a rotary mechanical descaling device. By setting parallel and rotatable rollers one and two, after the target bar is placed on them, the main motor drives rollers one and / or roller two to rotate, causing the target bar to also rotate around its own axis. Because roller one has spiral protrusions, when in contact with the surface of the target bar, it not only drives the target bar to rotate, but also, due to the weight of the target bar, crushes the oxide scale on its surface. Simultaneously, the ends of the target bar cannot move axially due to the obstruction of the end scrapers. Therefore, the spiral protrusions also generate an axial sliding peeling force on the oxide scale on the surface of the target bar, further loosening and removing the oxide scale. Meanwhile, the evenly distributed straight grooves on roller two increase the contact area with the surface of the target bar. Friction further peels off the remaining oxide scale after the first roller has been loosened. On the other hand, since the location of the straight groove essentially creates a break on the outer surface of the second roller, the straight groove also causes the target bar to jump radially, resulting in an impact between the target bar and the surfaces of the first and second rollers (the frequency and amplitude of this impact are determined by the rotational speed of the first and second rollers and the width and depth of the straight groove). This further loosens the remaining oxide scale, which is ultimately removed cleanly under the above synergistic effect. At the same time, due to the action of the end scraper, the oxide scale at both ends of the target bar is also removed, which has the advantages of good removal effect and fast speed. Spraying through the nozzles causes the oxide scale dust to be sprayed, collected, and settled in the aggregate bottom shell, effectively protecting the working environment.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0036] Please see Figures 1 to 5 A rotary mechanical descaling device includes a first roller 1, a second roller 2, a main motor 8, a bracket 3, and an end scraper 4, wherein:

[0037] The parallel spacing between roller 1 and roller 2 is rotatable, and the size of the spacing can be specifically designed according to the diameter of the target bar stock, without specific limitations here; the main motor 8 is driven by roller 1 and / or roller 2 to drive the rotation of roller 1 and / or roller 2; the main motor 8 is mounted on the outside of the frame 10 and is driven by roller 1 and / or roller 2 through a chain drive or belt drive mechanism; when the main motor 8 is driven by only one of roller 1 or roller 2, the other roller 1 or roller 2 is a passive roller, that is, roller 1 or roller 2, as the active roller, drives roller 1 or roller 2, as the passive roller, to rotate by the action of the target bar stock, and in this process, the oxide scale is removed; when the main motor 8 is driven by both roller 1 and roller 2, both rollers rotate actively;

[0038] The bracket 3 is vertically mounted between roller 1 and roller 2, and the longitudinal direction of the bracket 3 is parallel to the axis of roller 1 and roller 2. The bracket 3 is used to support the target bar. When the bracket 3 descends to the set position, the target bar rolls into contact with roller 1 and roller 2 and disengages from the bracket 3. Roller 1 and / or roller 2 are used to make the target bar rotate around its own axis. When the bracket 3 rises to the set position, the target bar disengages from roller 1 and roller 2. The end scrapers 4 are respectively located at both ends of the longitudinal direction of the bracket 3 and can move closer to or further away from the bracket 3.

[0039] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 5A spiral protrusion 101 is provided on the outer circumference of roller 1, and a number of straight grooves 201 are evenly distributed on the outer circumference of roller 2. The longitudinal direction of the straight grooves 201 is parallel to the axis of roller 2. In this embodiment, the width of the straight groove is 6mm-8mm, the depth is 8mm-9mm, and the cross-section of the straight groove is trapezoidal.

[0040] According to the structure provided in this embodiment, by setting parallel and rotatable rollers 1 and 2, after the target bar is placed on them, the main motor 8 drives rollers 1 and / or 2 to rotate, causing the target bar to also rotate around its own axis. Since roller 1 has spiral protrusions 101, when in contact with the surface of the target bar, it not only drives the target bar to rotate, but also, due to the weight of the target bar, crushes the oxide scale on its surface with the spiral protrusions 101. Simultaneously, the two ends of the target bar cannot move axially due to the obstruction of the end scrapers 4. It is understandable that due to length errors, axial movement of the target bar a certain distance within the permissible range of the process is allowed. Therefore, the spiral protrusions 101 also contribute to the rotation of the target bar. The oxide scale on the surface of the target bar generates an axial sliding peeling force, further loosening and removing the oxide scale. Meanwhile, the straight grooves 201 evenly distributed on roller 2 increase the friction between the target bar and the surface of the target bar, further peeling off the oxide scale that has not yet detached after being loosened by roller 1. On the other hand, since the location of the straight grooves 201 essentially creates a break on the outer surface of roller 2, the location of the straight grooves 201 also causes the target bar to jump in the radial direction, thereby causing the target bar to impact with the surfaces of roller 1 and roller 2 (the frequency and amplitude of this impact are determined by the rotational speed of roller 1 and roller 2, as well as the width and depth of the straight grooves 201), further loosening the remaining oxide scale and finally removing it completely under the above synergistic effect.

[0041] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 5 The rotary mechanical descaling device also includes protective covers 5, which are installed in pairs on roller 1 and roller 2. The protective covers 5 can be separated from each other or closed to expose or close roller 1 and roller 2. When the two protective covers 5 are closed, roller 1 and roller 2, as well as the target bar, are enclosed inside to prevent oxide scale from flying out of the working area, ensuring safety and environmental protection. When the two protective covers 5 are open and separated, it is convenient to pick up and put down the target bar.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 5 The rotary mechanical descaling device also includes nozzles 6, which have several nozzles evenly distributed along the longitudinal direction of the bracket 3 on the cover 5 for spraying water mist into the cover 5. In this way, during the process of cleaning the oxide scale, the oxide scale dust is sprayed and collected and settled into the aggregate bottom shell 9, effectively protecting the working environment.

[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 5 The rotary mechanical descaling device also includes a material collection bottom shell 9, a waste discharge pipe 17, a screw 18, and a waste discharge motor 12, wherein:

[0044] The aggregate bottom shell 9 is located below roller 1 and roller 2, and is funnel-shaped with its wide opening facing roller 1 and roller 2. It is used to collect the oxide scale peeled off from the target bar stock by roller 1 and roller 2. The waste discharge pipe 17 is located at the bottom of the aggregate bottom shell 9 and is connected to the aggregate bottom shell 9. The screw 18 is located inside the waste discharge pipe 17 and is used to discharge the oxide scale inside the aggregate bottom shell 9 through the port of the waste discharge pipe 17. The waste discharge motor 12 is located at one end of the waste discharge pipe 17 and is connected to the screw 18 for transmission. In this way, the waste discharge motor 12 drives the screw 18 to rotate and promptly discharge the oxide scale deposited at the bottom of the aggregate bottom shell 9 to the outside, so that this rotary mechanical descaling device can work continuously. It is understood that a container or filter device can be set at the outlet of the waste discharge pipe 17 to collect the oxide scale and at the same time reuse the water in it in the water tank 11, thereby reducing water consumption.

[0045] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 5 The rotary mechanical descaling device also includes a rotary joint 24 and a water pump 7, wherein:

[0046] Rotary joints 24 are respectively located at both ends of roller 1 and roller 2. It can be understood that roller 1 and roller 2 have water passages for water flow, or that roller 1 and roller 2 are hollow roller structures, with the rotary joints 24 at both ends being rotary water connectors. One rotary joint 24 is used for water inlet, and the other rotary joint 24 is used for water outlet. Water pump 7 is connected to the corresponding rotary joint 24 and nozzle 6 via pipes, supplying water from water tank 11 to roller 1, roller 2, and nozzle 6. Thus, water pump 7 pumps water from water tank 11 through the rotary joint 24 at one end. Water is supplied to roller 1 and roller 2 to cool them. The rotary joint 24 at the other end leads the water out and back to the water tank 11, thus avoiding heat damage to the bearings at both ends. This allows the rotary mechanical descaling device to operate stably for a long time. At the same time, a common cooling device can be installed on the water tank 11 or the water supply pipe to force-cool the return water. The water is pumped to the nozzle 6 and atomized, which cools the inside of the cover 5 and also gathers oxide scale dust, accelerating its settling to the bottom of the aggregate bottom shell 9, thus preventing dust from polluting the working environment.

[0047] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 5The bracket 3 has several through grooves 301 formed on it, and the upper end of the bracket 3 is arc-shaped. In this way, the arc-shaped structure has good stability when placing and picking up the target bar material, and avoids rolling. The through grooves 301 are conducive to the falling off of the peeled oxide scale, and prevent it from accumulating in the bracket 3, so as to ensure the normal function of the bracket 3, and also has a good heat dissipation effect.

[0048] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 5 The rotary mechanical descaling device also includes a frame 10. Rollers 1 and 2 are both rotatably supported by the frame 10. It is understood that bearing seats and matching bearings are installed on the frame 10 to support both ends of rollers 1 and 2 respectively, ensuring smooth rotation. Guide rails 13 are provided at both ends of the frame 10, and sliding frames 14 are provided at both ends of the cover 5, slidably connected to the corresponding guide rails 13. The guide rails 13 are horizontally positioned and perpendicular to the axis of roller 1. An opening cylinder 15 is hinged to the frame 10, and its output end is connected to the sliding frame 14, used to drive the cover 5 to open and close, thus ensuring smooth opening and closing of the cover 5. It is understood that through the above configuration, this rotary mechanical descaling device has a stable main structure, ensuring stable operation of each component and improving the overall reliability of the machine.

[0049] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 5 The rotary mechanical descaling device also includes an end cylinder 16 and a guide plate 19, wherein:

[0050] An end cylinder 16 is mounted on the frame 10 and its output end is connected to the end scraper 4. It drives the end scrapers 4 to move away from or closer to the target bar and to impact the end face of the target bar at a set frequency. The two end scrapers 4 have teeth on opposite sides. A guide plate 19 is located above the aggregate bottom shell 9 and connected to the frame 10 at both ends. A sliding plate 20 is connected to the bottom of the end scrapers 4, and the two ends of the sliding plate 20 slide in cooperation with the guide plate 19. According to the structure provided in this embodiment, on the one hand, the end cylinder 16 can push the end scrapers 4 to give the target bar a stable axial position; on the other hand, it can make the end scrapers 4 impact the end face of the target bar at a set frequency. Thus, at the instant the end scrapers 4 leave the end of the target bar, they can... While effectively reducing the rotational resistance of the target bar, the impact of the end scraper also removes the oxide scale from both ends of the target bar, resulting in good cleaning effect and high speed. Based on the same principle, at the instant the end scraper 4 contacts the end face of the target bar, the rotational resistance of the target bar increases momentarily. This also increases the peeling force of roller 1 and roller 2 on the oxide scale on the outer surface of the target bar, making it easier to clean the oxide scale. The toothed design further enhances the crushing of oxide scale and improves the cleaning effect. The sliding cooperation between the two ends of the slide plate 20 and the guide plate 19 provides stronger anti-overturning stability for the end scraper 4, ensuring that the end scraper 4 is in a stable position and will not rotate with the target bar.

[0051] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 5 The rotary mechanical descaling device also includes a lifting rod 21. In this embodiment, the lifting rod 21 slides vertically through the polymer bottom shell 9, with its upper end connected to the bottom of the bracket 3 and its lower end connected to a linear drive power source for driving the bracket 3 to move up and down. A sealing seat 23 is provided on the polymer bottom shell 9. The sealing sleeve 22 seals and connects the sealing seat 23 and the bracket 3 at both ends and seals and encloses the lifting rod 21. It is understood that the linear drive power source can be a cylinder, a lead screw nut, or a linear drive module, etc. According to the above structure provided in this embodiment, the lifting and lowering of the bracket 3 can be easily controlled. At the same time, through the function of the sealing seat 23 and the sealing sleeve 22, dust and impurities such as oxide scale are prevented from entering the sliding mating pair of the lifting rod 21, ensuring the smooth lifting and lowering of the lifting rod 21, and also preventing the leakage of oxide scale and sewage.
