Description

Technical Field

[0001] This invention relates to the field of new energy vehicle technology, and more specifically, to a stainless steel production equipment for forming automotive battery casings. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the power battery casing is a key component to ensure the safety and service life of the battery cells. Currently, stainless steel is the mainstream material used to manufacture it. The production process of stainless steel for battery casings usually involves first smelting the raw materials into molten steel and then continuously casting it into a steel billet. Then, it undergoes hot rolling, pickling, and multiple cold rolling processes to control the thickness and surface condition of the sheet. Subsequently, annealing is performed to eliminate work hardening and improve stamping performance. After finishing and slitting, finished stainless steel strips are obtained, which are then uncoiled, cut, and stamped to form the battery casing.

[0003] Because the quality requirements for stainless steel raw materials for power battery casings are stringent, if oxide scale remains in the hot-rolled steel billet, it is easily pressed into the steel matrix during the rolling process, forming pits, depressions, and peeling. This defect is difficult to remove through subsequent hot rolling, cold rolling, and polishing, resulting in poor appearance and deterioration of corrosion resistance in the finished casing. Therefore, the industry generally uses high-pressure water descaling machines to pre-treat the steel billet. The equipment uses a high-pressure pump station to pressurize water, which is then sprayed at high speed through fan-shaped nozzles onto the high-temperature steel billet before hot rolling. The iron oxide scale is rapidly cooled and shrinks, cracking, and the high-pressure water, through impact and wedging, effectively removes the scale. Descaling removes scale by penetrating into gaps, resulting in only a slight cooling of the billet surface while maintaining the overall high temperature required for rolling, without interfering with subsequent hot rolling operations. However, existing high-pressure water descaling machines typically use single-row, fixed-angle spray heads arranged along the billet's travel direction. This limits the spray coverage and reduces water flow overlap. Furthermore, the insufficient frequency of single-row water flow impacts makes it difficult to fully break down and remove the oxide scale, leading to incomplete descaling and residual iron oxide scale. This results in the aforementioned plate defects and subsequent deterioration of the casing processing. Therefore, we propose a stainless steel production equipment for forming automotive battery casings. Summary of the Invention

[0010] Preferably, the flow channel is an arc-shaped strip-shaped channel structure, and when the rotating component and the striking rod reciprocate, the drain hole is always connected to the inner cavity of the fixed cylinder through the flow channel.

[0011] Preferably, the outer circumferential wall of the rotating cylinder is connected to multiple cams, and the protrusions of the multiple cams are arranged in a spiral winding path. Each set of fan-shaped nozzles is arranged between every two cams. The side wall of the rotating component is integrally formed with a lever plate. When the rotating cylinder drives the cams to rotate synchronously, the protrusions of the cams intermittently abut against the lever plate, causing the rotating component to rotate around the fixed cylinder as the axis.

[0014] Preferably, the spray direction of the second output end of the fan-shaped nozzle is obliquely downward and deflected towards the rotating part; after the striking rod swings downward and completes the striking action, the spray direction of the second output end of the fan-shaped nozzle is aligned with the intersection of the edge of the wedge-shaped structure of the pressure table and the surface of the steel billet; as the striking rod swings from the lower dead point to the upper limit of rotation, the high-pressure water flow from the second output end of the fan-shaped nozzle forms a continuous sweeping state along the top inclined surface of the pressure table.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention designs the descaling mechanism to consist of a pre-scaling component and a fine descaling component. When the roller conveyor transports the high-temperature steel billet obtained through continuous casting, the rotating drum drives the fan-shaped nozzles on the outer wall to rotate, performing a sweeping high-pressure water jet on the surface of the steel billet. First, the high-pressure water jet impacts and breaks down and washes away most of the oxide scale. Then, the steel billet moves to the position of the fine descaling component, where the sharp wedge-shaped structure of the pressure table directly contacts the surface of the steel billet, scraping off the stubborn oxide scale remaining after pre-scaling. The two processes work together to remove the oxide scale from the surface of the steel billet layer by layer, effectively avoiding defects such as pitting, dents, and reduced corrosion resistance in subsequent stainless steel materials and automotive battery casings caused by oxide scale residue, thus ensuring the quality of raw material processing.

[0016] 2. This invention designs the scale-flushing assembly as a dynamic-static coupling structure between a support cylinder and a rotating cylinder. During high-pressure water scale-flushing operations, high-pressure water is delivered by an external high-pressure pump to a three-way pipe and introduced into the internal flow channel of the support cylinder. It is then guided through the arc-shaped channel on the annular protrusion and finally ejected at high speed from a fan-shaped nozzle. Because the opening of the arc-shaped channel in the support cylinder is designed to face obliquely downwards, opposite to the billet's direction of travel, during the rotation of the rotating cylinder, only the fan-shaped nozzle in the lower working area discharges water; the rest... The nozzles in the non-working area interrupt the flow, forming a dynamic sweeping scale removal effect on the top of the billet; multiple sets of fan-shaped nozzles are arranged linearly along the axial direction. After each row of fan-shaped nozzles sweeps, the next row can form a continuous replacement spray, with no blind spots throughout the process, forming an uninterrupted dynamic sweeping scale removal effect. At the same time, the rotational motion allows the water flow to impact the surface of the billet at multiple angles at any time. Compared with the traditional fixed single-row and multi-row spray structure, it greatly improves the water flow impact coverage and effect, and strengthens the ability to break and peel off the oxide scale.

[0017] 3. The present invention also incorporates multiple striking rods in the fine descaling assembly, with fan-shaped nozzles installed on the side walls of the striking rods. When high-pressure water flushing is performed, the high-pressure water is delivered to the three-way pipe by an external high-pressure pump. Part of the high-pressure water flow is introduced into the internal flow channel of the support cylinder of the flushing assembly through the three-way pipe, and is used by multiple sets of fan-shaped nozzles to perform continuous dynamic sweeping and flushing operations. The other part of the high-pressure water flow flows into the inner cavity of the fixed cylinder through another branch of the three-way pipe, and then passes through the flow groove, drainage hole and the internal channel of the striking rod in sequence, and finally sprays out from the fan-shaped nozzles, forming a secondary flushing of the steel billet surface, washing away residual microscale, and further improving the overall descaling effect.

[0018] 4. This invention also incorporates a cam structure designed on the outer circumference of the rotating cylinder. The protrusions of multiple cams are arranged in a spiral winding path. When the scale removal assembly performs continuous dynamic sweeping and scale removal, i.e., when the rotating cylinder rotates, the cams rotate synchronously. The spirally arranged protrusions will intermittently touch and push the levers on each rotating component, driving the rotating component to rotate around the fixed cylinder as the axis until the cam protrusions separate from the levers and lose their pushing force. Then, the striking rod falls rapidly under the gravity of its own striking counterweight and strikes the top of the pressure table. The impact force is transmitted to the steel billet through the pressure table, causing the steel billet to produce high-frequency instantaneous vibration. This can loosen and remove the stubborn oxide scale scraped off by the wedge-shaped end of the pressure table, and also shake off the fine scales on the steel billet. This movement drives the striking rod to rise and fall cyclically, so that the striking counterweight regularly strikes the top of the pressure table, further improving the effect of secondary scale removal.

[0019] 5. This invention designs the flow channel as an arc-shaped strip structure, with the second fan-shaped nozzle angled downwards and biased towards the rotating part. This not only ensures that the drainage hole is always connected to the inner cavity of the fixed cylinder through the flow channel during the reciprocating swing of the rotating part and the striking rod, but also that the second fan-shaped nozzle, which swings synchronously with the rotating part, continuously changes the spray angle. That is, after the striking rod swings down to complete the strike, its water flow is precisely aimed at the intersection of the wedge-shaped edge of the pressure table and the steel billet, washing away the peeled oxide scale and promptly removing the detached oxide scale to prevent its secondary adhesion. This achieves the simultaneous execution of mechanical vibration, scraping, and secondary water spraying for descaling. Furthermore, during the upward swing of the striking rod, the high-pressure water flow continuously sweeps along the top inclined surface of the pressure table, which can clean the residual scale on the pressure table and achieve a self-cleaning effect.

[0020] 6. The present invention designs the sidewall of the cam's protruding structure as an inclined surface structure, so that a gradually expanding channel is formed between each two adjacent cams. This gradually expanding channel can ensure that the fan-shaped nozzle between each two cams can effectively spray water in a fan shape, so that the spraying area of ​​the two adjacent fan nozzles is covered, avoiding the cam from blocking the fan-shaped water flow and reducing the spray blind area.

Detailed Implementation

[0035] like Figures 1 to 13 As shown, the present invention relates to a stainless steel production equipment for forming automotive battery housings, including a high-pressure water descaling device, which includes a first fixed frame 1 and a second fixed frame 2; a descaling mechanism 3 and a roller conveyor 4 are arranged between the first fixed frame 1 and the second fixed frame 2; the roller conveyor 4 is arranged below the descaling mechanism 3, and the roller conveyor 4 is a conventional high-temperature resistant roller conveyor used to transport steel billets 5 at high temperatures.

[0036] Specifically, the descaling mechanism 3 consists of a broad-scaling component 31 and a fine descaling component 32. The broad-scaling component 31 includes a rotating cylinder 3101, and multiple fan-shaped nozzles 3102 are arranged on the outer circumference of the rotating cylinder 3101. The fan-shaped nozzles 3102 are conventional nozzle structures capable of spraying high-pressure water flow in a fan-shaped area. The rotating cylinder 3101 can rotate and drive the multiple fan-shaped nozzles 3102 to perform sweeping high-pressure water spray on the surface of the billet 5 to remove the oxide scale from the surface of the billet 5. The fine descaling component 32 includes a pressure table 3201, one end of which is a pointed wedge structure. The pointed wedge structure is used to scrape and peel off the oxide scale on the surface of the billet 5.

[0037] This invention designs the descaling mechanism 3 to consist of a pre-scaling component 31 and a fine descaling component 32. When the roller conveyor 4 conveys the high-temperature steel billet 5 obtained through continuous casting, the rotating cylinder 3101 drives the fan-shaped nozzle 3102 on the outer wall to rotate, performing a sweeping high-pressure water jet on the surface of the steel billet 5. First, the high-pressure water jet impacts and breaks down and washes away most of the oxide scale. Then, the steel billet 5 moves to the position of the fine descaling component 32, where the sharp wedge-shaped structure of the pressure table 3201 directly contacts the surface of the steel billet 5, scraping off the stubborn oxide scale remaining after pre-scaling. The two processes work together to remove the oxide scale from the surface of the steel billet 5 layer by layer, effectively avoiding defects such as pitting, dents, and reduced corrosion resistance in subsequent stainless steel materials and automotive battery casings caused by residual oxide scale, thus ensuring the quality of raw material processing.

[0038] In an embodiment of the present invention, the scale-spreading assembly 31 further includes a motor 3103 mounted on the top of the first fixed frame 1. The output end of the motor 3103 movably passes through the side wall of the first fixed frame 1 and is connected to a drive gear 3104. A transmission gear 3105 is also rotatably connected to the side wall of the first fixed frame 1, and the drive gear 3104 meshes with the transmission gear 3105. The scale-spreading assembly 31 also includes a support cylinder 3106, one end of which is connected to the side wall of the second fixed frame 2, and the other end passes through the first fixed frame 1. A three-way pipe 6 is connected to the side wall; the rotating cylinder 3101 is rotatably mounted on the support cylinder 3106 via the bearing 3107. A driven gear 3111 is arranged on the outer circumference of the rotating cylinder 3101, and the driven gear 3111 meshes with the transmission gear 3105; the motor 3103 drives the driving gear 3104 to rotate, and drives the transmission gear 3105 to rotate synchronously through meshing transmission. The transmission gear 3105 then meshes with the driven gear 3111, driving the rotating cylinder 3101 on the support cylinder 3106 to rotate.

[0039] In an embodiment of the present invention, the inner cavity of the support cylinder 3106 is connected to the inner cavity of the branch pipe of the tee pipe 6, and the main inlet of the tee pipe 6 is connected to the output end of the external high-pressure pump water supply equipment; the outer circumferential wall of the support cylinder 3106 is integrally formed with multiple annular protrusions 3108, and the side wall of the annular protrusions 3108 is provided with an arc-shaped channel 3109, which is connected to the inner cavity of the support cylinder 3106, and the opening of the arc-shaped channel 3109 faces obliquely downward in the opposite direction to the travel direction of the billet 5; the inner circumferential wall of the rotating cylinder 3101 is provided with multiple annular grooves 3110, and the annular protrusions 3108 are sealed and embedded in the annular grooves 3110, forming a rotational fit; each group of fan-shaped nozzles 3102 is arranged in an annular array on the outer circumferential wall of the rotating cylinder 3101, and the multiple groups of fan-shaped nozzles 3102 are arranged in a linear array, and the inlet of each group of fan-shaped nozzles 3102 is connected to the annular groove 3110.

[0040] This invention designs the scale-flushing assembly 31 as a dynamic-static coupling structure between the support cylinder 3106 and the rotating cylinder 3101. During high-pressure water scale-flushing operations, high-pressure water is delivered by an external high-pressure pump to the three-way pipe 6, then introduced into the internal flow channel of the support cylinder 3106, guided by the arc-shaped channel 3109 on the annular protrusion 3108, and finally ejected at high speed from the fan-shaped nozzle 3102. Figure 12As shown, because the opening of the arc-shaped channel 3109 of the support cylinder 3106 is designed to face downwards at an angle opposite to the direction of travel of the billet 5, during the rotation of the rotating cylinder 3101, only the fan-shaped nozzles 3102 in the lower working area conduct water flow, while the nozzles in the other non-working areas are cut off, forming a dynamic sweeping scale removal on the top of the billet 5; multiple sets of fan-shaped nozzles 3102 are arranged linearly along the axial direction, and after each row of fan-shaped nozzles 3102 sweeps, the next row can form a continuous supplementary spray, with no blind spots in operation throughout the process, forming an uninterrupted dynamic sweeping scale removal. At the same time, the rotational motion allows the water flow to impact the surface of the billet 5 at multiple angles at any time. Compared with the traditional fixed single-row and multi-row spray structure, it greatly improves the water flow impact coverage and effect, and strengthens the ability to break and peel off the oxide scale.

[0041] In an embodiment of the present invention, the fine descaling assembly 32 further includes a fixed cylinder 3202. Multiple striking rods 3203 are rotatably arranged on the outer circumference of the fixed cylinder 3202. The striking rods 3203 and the rotating cylinder 3101 form a linkage structure. When the rotating cylinder 3101 rotates, it drives the multiple striking rods 3203 to sequentially and cyclically strike the top of the pressure table 3201. The impact force is transmitted to the steel billet 5 through the pressure table 3201, generating instantaneous impact vibration on the steel billet 5. This can cause the oxide scale to loosen and fall off. Simultaneously, the impact force is transmitted through the pressure table 3201, avoiding direct striking of the steel billet 5 at high temperatures, which could easily cause dents and deformation, affecting the initial shape of the steel billet 5. One end of the fixed cylinder 3202 is connected to the side wall of the second fixed frame 2, and the other end penetrates the side wall of the first fixed frame 1 and is connected to another branch pipe of the three-way pipe 6, forming a continuous connection. Multiple annular grooves 3204 are formed on the outer circumference of the 3202. A flow groove 3205 is formed on the side wall of the annular groove 3204, and the flow groove 3205 is connected to the inner cavity of the fixed cylinder 3202. One end of the striking rod 3203 is connected to a rotating part 3206 and the other end is connected to a striking counterweight 3207. The rotating part 3206 is rotatably sleeved on the fixed cylinder 3202, and an annular block 3208 is integrally formed on the inner circumference of the rotating part 3206. The rotating part 3206 forms a rotational engagement with the annular groove 3204 through the annular block 3208. A drain hole 3209 is formed on the side wall of the annular block 3208. The drain hole 3209 is connected to the inner cavity of the fixed cylinder 3202 through the flow groove 3205. A fan-shaped nozzle 3210 is also connected to the side wall of the striking rod 3203. The drain hole 3209 is connected to the inlet of the fan-shaped nozzle 3210 through the inner cavity of the striking rod 3203.

[0042] The present invention also incorporates multiple striking rods 3203 in the fine descaling assembly 32, with fan-shaped nozzles 3210 mounted on the side walls of the striking rods 3203. When high-pressure water flushing is performed, the high-pressure water is delivered to the three-way pipe 6 by an external high-pressure pump. Part of the high-pressure water flow is introduced into the internal flow channel of the support cylinder 3106 of the flushing assembly 31 through the three-way pipe 6, and is used for continuous dynamic sweeping and flushing operations by multiple sets of fan-shaped nozzles 3102. The other part of the high-pressure water flow flows into the inner cavity of the fixed cylinder 3202 through another branch of the three-way pipe 6, and then passes through the flow groove 3205, the drain hole 3209 and the internal channel of the striking rods 3203 in sequence, and finally sprays out from the fan-shaped nozzles 3210, forming a secondary flushing of the surface of the steel billet 5, washing away residual microscale, and further improving the overall descaling effect.

[0043] In another embodiment of the present invention, a plurality of cams 3112 are connected to the outer circumference of the rotating cylinder 3101. The protrusions of the plurality of cams 3112 are arranged in a spiral winding path, and each set of fan-shaped nozzles 3102 is arranged between every two cams 3112. The rotating component 3206 has a paddle plate 3211 integrally formed on its side wall. When the rotating cylinder 3101 drives the cams 3112 to rotate synchronously, the protrusions of the cams 3112 intermittently abut against the paddle plate 3211, thereby driving the rotating component 3206 to rotate around the fixed cylinder 3202 as the axis.

[0044] The present invention also incorporates a cam 3112 structure designed on the outer circumference of the rotating cylinder 3101. The protrusions of multiple cams 3112 are arranged in a spiral winding path. When the scale-sweeping assembly 31 performs continuous dynamic scale sweeping, that is, when the rotating cylinder 3101 rotates, the cams 3112 rotate synchronously. The spirally arranged protrusions will intermittently touch and push the levers 3211 on each rotating component 3206, driving the rotating component 3206 to rotate around the fixed cylinder 3202 as the axis, until the protrusions of the cams 3112 separate from the levers 3211. After losing its pushing force, the striking rod 3203 falls rapidly back under the gravity of its own striking counterweight 3207, striking the top of the pressure table 3201. The impact force is transmitted to the steel billet 5 through the pressure table 3201, causing the steel billet 5 to produce high-frequency instantaneous vibration. This can loosen and remove the stubborn oxide scale scraped off by the wedge-shaped end of the pressure table 3201, and also shake off the fine scales on the steel billet 5. This movement drives the striking rod 3203 to rise and fall cyclically, so that the striking counterweight 3207 strikes the top of the pressure table 3201 regularly, further improving the effect of secondary scale removal.

[0045] In another embodiment of the present invention, the flow channel 3205 is an arc-shaped strip-shaped channel structure. During the reciprocating swing of the rotating member 3206 and the striking rod 3203, the drain hole 3209 is always connected to the inner cavity of the fixed cylinder 3202 through the flow channel 3205. The spray direction of the output end of the fan-shaped nozzle 3210 is obliquely downward and tilted towards the rotating member 3206. After the striking rod 3203 swings downward and completes the striking action, the spray direction of the output end of the fan-shaped nozzle 3210 is aligned with the pressure table 3201. At the intersection of the edge of the wedge-shaped structure and the surface of the billet 5; as the striking rod 3203 swings from the lower dead center to the upper limit of rotation, the high-pressure water flow from the output end of the fan-shaped nozzle 3210 forms a continuous sweeping state along the top slope of the pressure table 3201; wherein, the flow groove 3205 adopts an arc-shaped strip structure, which can ensure that when the rotating part 3206 and the striking rod 3203 swing back and forth, the drain hole 3209 is always connected to the inner cavity of the fixed cylinder 3202 through the flow groove 3205, so that the fan-shaped nozzle 3210 can continuously and stably supply water.

[0046] This invention designs the flow channel 3205 as an arc-shaped strip structure and arranges the fan-shaped nozzle 3210 obliquely downward and biased towards the rotating component 3206. This not only ensures that the drainage hole 3209 is always connected to the inner cavity of the fixed cylinder 3202 through the flow channel 3205 during the reciprocating swing of the rotating component 3206 and the striking rod 3203, but also that the fan-shaped nozzle 3210, which swings synchronously with the rotating component 3206, continuously changes the spray angle. That is, after the striking rod 3203 swings down to complete the striking, its water flow is precisely aimed at the intersection of the wedge-shaped edge of the pressure table 3201 and the steel billet 5, washing away the peeled oxide scale and promptly removing the detached oxide scale to prevent its secondary adhesion. This achieves the simultaneous execution of mechanical vibration, scraping, and secondary water spraying for descaling. Furthermore, during the upward swing of the striking rod 3203, the high-pressure water flow continuously sweeps along the top inclined surface of the pressure table 3201, which can clean the residual scale on the pressure table 3201 and achieve a self-cleaning effect.

[0047] In an embodiment of the present invention, a movable groove 101 is provided on the side wall of the first fixed frame 1, a vertical guide rod 102 is arranged in the movable groove 101, a spring 103 is sleeved on the outer circumference of the guide rod 102, and a cylinder 104 is installed on the side wall of the movable groove 101; a groove structure with the same groove structure as the movable groove 101 is provided on the side wall of the second fixed frame 2, and the same structural components as those in the movable groove 101 are arranged in the groove structure; a support plate 3212 is connected to the side wall of the pressure table 3201, the support plate 3212 is movably sleeved on the guide rod 102, and the spring 103 is arranged on the top of the support plate 3212; when the output end of the cylinder 104 extends, it can push the support plate 3212 to compress the spring 103 and move upward; when the output end of the cylinder 104 retracts, it can separate from the support plate 3212.

[0048] When the cylinder 104 extends, it pushes the support plate 3212 to move upward along the guide rod 102 and compresses the spring 103, causing the pressure table 3201 to rise. This allows the pressure table 3201 to avoid the steel billet 5 when it enters the billet 5 in the initial stage. When the steel billet 5 moves to the bottom of the pressure table 3201, the cylinder 104 retracts and disengages from the support plate 3212. The spring 103 releases its elastic force to push the support plate 3212 and the pressure table 3201 downward, so that the pressure table 3201 fits against the surface of the steel billet 5 to carry out scraping and descaling operations. The symmetrical structure of the first fixed frame 1 and the second fixed frame 2 can ensure that the pressure table 3201 rises and falls smoothly and is subjected to uniform force.

[0049] In an embodiment of the present invention, the sidewall of the protruding structure of the cam 3112 is an inclined surface structure, and a gradually expanding axial channel is formed between each two adjacent cams 3112 through the inclined surface structure. Figure 13 As shown, the present invention designs the sidewall of the protruding structure of the cam 3112 as an inclined surface structure, so that a gradually expanding channel is formed between each two adjacent cams 3112. This gradually expanding channel can ensure that the fan-shaped nozzle 3102 between each two cams 3112 can effectively spray water in a fan shape, so that the spraying area of ​​the two adjacent fan-shaped nozzles 3102 is covered, avoiding the cam 3112 from blocking the fan-shaped water flow and reducing the spray blind area.

[0050] Working principle: This embodiment provides a stainless steel production equipment for forming automotive battery housings. During use, an external high-pressure pump water supply device delivers high-pressure water to the three-way pipe 6, and the water flow is divided into two paths to supply the anti-scaling assembly 31 and the fine descaling assembly 32 respectively; at the same time, the motor 3103 is started, and the motor 3103 drives the drive gear 3104, the transmission gear 3105 and the driven gear 3111 to mesh and drive in sequence, driving the rotating cylinder 3101 to rotate at a constant speed around the support cylinder 3106; Next, the high-temperature steel billet 5 is conveyed forward by the roller conveyor 4 and first enters the scale-removing station; high-pressure water flows into the inner cavity of the support cylinder 3106 through the three-way pipe 6, and is introduced into the output end of the annular groove 3110 through the arc-shaped channel 3109 on the annular protrusion 3108, and is ejected by the fan-shaped nozzle 3102; due to the orientation restriction of the arc-shaped channel 3109, water is only discharged from the fan-shaped nozzle 3102 in the working area on the lower side of the rotating cylinder 3101, forming a continuous dynamic sweeping high-pressure water jet scale-removing effect as the rotating cylinder 3101 rotates, impacting the surface of the steel billet 5 from multiple angles, breaking and washing off most of the oxide scale; at the same time, the rotating cylinder 3101 drives the cams 3112 arranged in multiple spiral paths on the outer wall to rotate synchronously; Next, the billet 5 continues to move forward to the fine descaling station. Previously, the cylinder 104 extends to push the support plate 3212 to move upward along the guide rod 102 and compress the spring 103, raising the pressure table 3201 to avoid the billet 5. When the billet 5 has completely reached below the pressure table 3201, the cylinder 104 retracts, the spring 103 resets and drives the pressure table 3201 to descend, so that the sharp wedge-shaped structure of the pressure table 3201 fits against the surface of the billet 5, scraping off the remaining stubborn oxide scale. Furthermore, during the rotation of the cam 3112, its protruding structure intermittently actuates the lever 3211, causing the rotating component 3206 and the striking rod 3203 to swing around the fixed cylinder 3202; when the cam 3112 disengages from the lever 3211, the striking counterweight 3207 falls back quickly under gravity and strikes the top of the pressure table 3201. The impact force is transmitted to the surface of the billet 5 through the pressure table 3201, generating high-frequency instantaneous vibration, which causes the oxide scale to loosen and fall off. Furthermore, another high-pressure water stream flows through the three-way pipe 6 into the inner cavity of the fixed cylinder 3202, and then passes through the flow channel 3205, the drain hole 3209, and the inner cavity of the striking rod 3203 before being sprayed out from the fan-shaped nozzle 3210. When the striking rod 3203 swings down to strike, the water flow from the fan-shaped nozzle 3210 is aimed at the contact position between the pressure platform 3201 and the steel billet 5, promptly flushing away the detached oxide scale and preventing secondary adhesion. When the striking rod 3203 swings back upward, the water flow sweeps along the top surface of the pressure platform 3201, completing the self-cleaning of the pressure platform 3201. The entire equipment effectively removes the oxide scale from the surface of the steel billet 5 through multiple combinations of flushing, scraping, vibration, and secondary water spraying.
