Description

Technical Field

[0001] This invention relates to the field of shell column molding technology, and more specifically, to a molding device for an outdoor switchgear shell column. Background Technology

[0002] Outdoor switching stations, as key equipment in power distribution network systems, typically consist of a shell structure assembled from components such as shell columns, beams, top plates, bottom plates, and side plates. Among these, the shell columns, as the main load-bearing components, are often C-shaped, and their manufacturing quality directly affects the overall structural strength and assembly precision of the switching station. Currently, these columns are mostly formed from sheet metal through processes such as punching and roll bending.

[0003] In the existing column processing technology, the punching process and the roll forming process are usually carried out independently. After the sheet metal is uncoiled and leveled, it is first punched and then sent to the roll forming unit to complete the bending and forming.

[0004] However, after the punching process is completed, metal debris will inevitably be generated at the punched part. This debris will adhere to the surface of the sheet. If this debris is not effectively cleaned before roll forming, it will cause defects such as pressure marks and scratches on the surface of the sheet during the subsequent forming process, affecting the surface quality of the finished product.

[0005] In addition, when the punching unit is completed and the punching mechanism is reset, the debris attached to the punching head will remain in the hole. If the debris in the hole is not cleaned before roll forming, it will cause the hole to crack due to rigid extrusion during the subsequent forming process, affecting the production quality of the column and further affecting the use of the column. A forming device for the shell column of an outdoor switchgear is proposed to improve the existing problems. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a molding device for the shell column of an outdoor switchgear.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A forming device for the shell column of an outdoor switchgear includes a mounting frame. A punching unit, a slag cleaning unit, and a forming unit are sequentially arranged on the mounting frame along the conveying direction of the sheet material. The sheet material is driven and conveyed by a transmission mechanism, and passes through the punching unit to complete punching, the slag cleaning unit to complete slag removal, and the forming unit to complete roll forming.

[0008] The slag removal unit includes a slag removal component and a cleaning component.

[0009] The slag removal assembly includes a first baffle structure, a suction mechanism, a second baffle structure, and a collection tank. The top of the first baffle structure is connected to the suction mechanism, and the second baffle structure is disposed between the first baffle structure and the punching unit.

[0010] The first baffle structure includes two symmetrically arranged first descaling structures for removing debris from the top of the board. The second baffle structure includes two symmetrically arranged second descaling structures for removing debris from the bottom of the board, and the collection trough is used to collect debris from below the board.

[0011] The cleaning assembly includes a support frame, a bottom surface brushing mechanism, and an in-hole cleaning mechanism. The support frame is fixedly mounted on a mounting bracket. The bottom surface brushing mechanism is located below the board and is used to clean debris from the bottom surface of the board.

[0012] The slag removal mechanism is located above the plate and can move vertically up and down to penetrate the punch holes in the plate and remove the debris inside the holes.

[0013] The invention is further configured such that the suction mechanism is a negative pressure suction pipe structure. The first baffle structure is fixedly connected to the support frame.

[0014] The first shield structure includes two sets of symmetrically arranged first upright plates, two sets of symmetrically arranged first side plates, and a top plate. Both sets of first side plates are arranged at an incline. The two sides of each set of first side plates are fixedly connected to the two sets of first upright plates respectively. The tops of the two sets of first upright plates and the two sets of first side plates are connected to the top plate respectively. The two sets of first upright plates, the two sets of first side plates, and the top plate together form a shield with an opening at the lower end.

[0015] The end of the suction mechanism is sealed and installed on the top plate, and is connected to the internal cavity of the first baffle structure.

[0016] Each of the two sets of first side plates has a first slag removal structure on the side closest to the board material. The first slag removal structure is used to remove the debris attached to the top of the board material.

[0017] The present invention is further configured such that: the first slag removal structure includes a floating component and a slag removal knife, the floating component is hinged to a first side plate, the slag removal knife is fixedly connected to the side of the floating component near the plate, and the scraping edge of the slag removal knife elastically abuts against the upper surface of the plate, for scraping off the slag adhering to the punched part during the plate conveying process.

[0018] The present invention is further configured such that: the second baffle structure includes two sets of symmetrically arranged second vertical plates and two sets of symmetrically arranged second side plates, each set of second vertical plates is fixedly connected to the mounting frame on both sides, the two sets of second side plates are inclined, each set of second side plates is connected to the second vertical plate on both sides, and the two sets of second vertical plates and the two sets of second side plates form a slag removal channel with openings at both ends.

[0019] A second slag removal structure is provided on the side of the second side plate of each group near the plate. The second slag removal structure has the same structure as the first slag removal structure. The scraping blade of the second slag removal structure elastically abuts against the lower surface of the plate and is used to scrape off the debris attached to the punched part during the plate conveying process. The debris scraped off by the second slag removal structure falls into the inside of the collection tank under the action of gravity.

[0020] The present invention is further configured such that the bottom surface slag brushing mechanism includes a mounting groove, a roller brush, and a drive motor.

[0021] The mounting slot is located in the middle of the support frame. The bottom of the mounting slot is fixedly connected to the top of the mounting frame. Both ends of the roller brush are rotatably mounted in the mounting slot through connecting shafts. The drive motor is fixedly mounted on one side of the support frame. The output shaft of the drive motor is connected to the connecting shaft of the roller brush. The drive motor is used to drive the roller brush to rotate and sweep away debris from the bottom surface of the board.

[0022] The invention is further configured such that: four sets of annular receiving grooves are distributed circumferentially along the outer periphery of the roller brush, and each set of annular receiving grooves is provided with a slag-removing brush. When the slag-removing mechanism in the hole moves downward, it can extend into the annular receiving groove, and the slag-removing brush is used to clean the debris adhering to the surface of the slag-removing mechanism in the hole.

[0023] The present invention is further configured such that the slag removal mechanism inside the hole includes a lifting drive component, a mounting plate, and four sets of slag removal rods.

[0024] The lifting drive component is fixedly installed on the top of the support frame, and its output end extends downward through the top of the support frame and is fixedly connected to the mounting plate. Each of the slag removal rods is fixedly installed at the bottom of the mounting plate, and the position of the slag removal rod corresponds to the position of the punching hole on the plate.

[0025] The invention is further configured such that: the inner dimension of the annular receiving groove is larger than the outer diameter of the slag removal rod; the slag removal rod can extend into the annular receiving groove under the drive of the lifting drive component; and the slag removal brush provided inside the annular receiving groove can remove the debris on the outside of the slag removal rod.

[0026] The end of the slag removal rod is designed with a tapered structure, which facilitates the slag removal rod to pass through the punch holes on the plate and enter the interior of the annular receiving groove.

[0027] The present invention is further configured such that: a plurality of guide structures are provided between the support frame and the mounting plate, the guide structures being used to guide the lifting and lowering movement of the mounting plate.

[0028] The present invention is further configured such that: the forming unit is a roll forming mechanism composed of multiple sets of rollers, used to roll form the plate after punching and cleaning into a C-shaped shell column.

[0029] In summary, this application includes at least one of the following beneficial technical effects: (1) The slag removal component and the cleaning component are arranged sequentially along the conveying direction. The slag removal component performs negative pressure suction and scraping to remove slag from the top of the plate and scrapes the bottom to remove slag and collects the slag in the collection tank. The slag removal mechanism in the hole of the cleaning component pushes the slag in the hole downward through the punch hole by lifting and lowering motion. The bottom surface brushing mechanism in the cleaning component performs roller brush cleaning on the bottom surface of the plate to clean the slag in the plate and reduce the impact of slag residue on the subsequent roll forming quality.

[0030] (2) The slag removal knife of the slag removal assembly is hinged to the first side plate through a floating part. The floating part adopts a spring rod structure and applies elastic bias pressure, so that the scraping edge of the slag removal knife elastically abuts against the upper surface of the plate. When the surface of the plate fluctuates during the conveying process, the spring rod swings adaptively, so that the scraping edge always fits the surface of the plate while avoiding rigid contact and scratching the plate, thus achieving slag removal and protection of the plate surface.

[0031] (3) By setting multiple sets of slag removal rods corresponding to the punching position of the plate, the lower end of the slag removal rod is set as a conical structure to facilitate alignment and penetration through the punching hole. Under the drive of the lifting drive, it penetrates the punching hole vertically and pushes out the slag embedded in the hole downward, thereby removing the slag in the hole.

[0032] (4) The outer periphery of the roller brush is provided with an annular receiving groove. A slag removal brush is installed in the annular receiving groove. After the slag removal rod completes the slag removal in the hole, it continues to descend and insert into the annular receiving groove under the drive of the lifting drive. When the roller brush rotates, the bristle bundles in the annular receiving groove sweep and clean the outer periphery of the slag removal rod, removing the debris attached to the surface of the slag removal rod. This reduces the possibility of the debris being carried back into the punch hole of the board or falling onto the surface of the board when the slag removal rod is reset, causing secondary pollution, and further improves the thoroughness of slag removal.

Detailed Implementation

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0047] Please see Figures 1-11 The present invention provides the following technical solutions: Example 1, see Figure 1 and Figure 11 A forming device for the shell column of an outdoor switchgear is mainly used for processing the C-type shell column 7 of an outdoor switchgear. After the punching process, a slag cleaning unit is set up to directly clean up the debris, and then roll forming is performed. This device includes a mounting frame 2, which is a long strip frame structure. The punching unit 1, the slag cleaning unit, and the forming unit 5 are arranged sequentially on the mounting frame 2 along the conveying direction of the plate 6.

[0048] See Figure 1 The sheet material 6 is driven and conveyed by the transmission mechanism on the mounting frame 2, and passes through the punching unit 1 to complete the punching process, the slag cleaning unit to complete the slag cleaning, and the forming unit 5 to complete the roll bending forming.

[0049] It should be noted that, in this embodiment, the transmission mechanism of the outdoor switchgear housing column forming device can adopt the conventional feeding roller friction transmission method in the field of roll forming, and is not specifically limited in this embodiment. The plate 6 is clamped by a pair of upper and lower rollers, and the plate 6 is driven to move linearly along the conveying direction by the static friction between the rollers and the plate 6. Simultaneously, an intermittent control scheme is implemented to achieve intermittent conveying at a fixed distance, matching the processing rhythm of punching, slag removal, and roll forming. Multiple sets of rollers in the downstream forming unit 5 also provide auxiliary conveying power synchronously, meeting the requirements for conveying stability during the roll forming and bending process of the plate 6.

[0050] See Figure 2 The slag removal unit includes a slag removal component 3 and a cleaning component 4 arranged sequentially along the conveying direction. The slag removal component 3 is used to remove slag from the top and bottom of the plate 6, and the cleaning component 4 is used to clean the bottom surface of the plate 6 and the inside of the holes. The slag removal component 3 and the cleaning component 4 work together to complete the comprehensive slag removal of the plate 6.

[0051] The forming unit 5 is located on the discharge side of the slag removal unit. It is a roll forming mechanism composed of multiple sets of sequentially arranged rollers, which is a conventional structure in the field of roll forming. After the slag-removed sheet 6 enters the forming unit 5, it is gradually bent and rolled by multiple sets of rollers, and finally formed into a shell column 7 with a C-shaped cross section.

[0052] During the slag removal process of board 6, the bottom and top of board 6 are first cleaned by the slag removal component 3. The specific structure of the slag removal component 3 is as follows: See Figure 2 The slag removal assembly 3 includes a first baffle structure 31 and a suction mechanism 32. The first baffle structure 31 is placed above the plate 6, and the top of the first baffle structure 31 is connected to the suction mechanism 32. The first baffle structure 31 is fixedly connected to the support frame 41.

[0053] See Figure 4 The first shield structure 31 includes two sets of symmetrically arranged first upright plates 311, two sets of symmetrically arranged first side plates 312, and a top plate 314. The two sets of first side plates 312 are arranged at an incline. The two sides of each set of first side plates 312 are fixedly connected to the two sets of first upright plates 311 respectively. The tops of the two sets of first upright plates 311 and the two sets of first side plates 312 are connected to the top plate 314 respectively. The two sets of first upright plates 311, the two sets of first side plates 312, and the top plate 314 enclose a shield with an opening at the lower end.

[0054] See Figure 2 The suction mechanism 32 is a negative pressure suction pipe structure. The end of the suction mechanism 32 is sealed and installed on the top plate 314 and is connected to the internal cavity of the first baffle structure 31.

[0055] When the slag removal component 3 is in operation, the first baffle structure 31 surrounds a local area above the plate 6, limiting the range of slag splashing, and at the same time gathering the negative pressure airflow; the negative pressure suction generated by the suction mechanism 32 acts on the surface of the plate 6 through the top of the baffle, sucking out and collecting the loose slag with the airflow.

[0056] The above structure can absorb the debris on the top of the plate 6. However, when the plate 6 is punched, debris will adhere to the edge of the hole. Therefore, the debris attached to the top and bottom of the plate 6 is further scraped off by the first debris removal structure 313 and the second debris removal structure 333 respectively.

[0057] See Figure 4 and Figure 5 The specific configuration and structure of the first slag removal structure 313 are as follows: Each of the two sets of first side plates 312 is provided with a first slag removal structure 313 on the side near the plate 6. The first slag removal structure 313 is used to remove the debris attached to the top of the plate 6.

[0058] See Figure 5 The first slag removal structure 313 includes a floating member 3131 and a slag removal knife 3132. The floating member 3131 is hinged to the first side plate 312, and the slag removal knife 3132 is fixedly connected to the side of the floating member 3131 near the plate 6. The scraping edge of the slag removal knife 3132 elastically abuts against the upper surface of the plate 6 and is used to scrape off the slag attached to the punched part during the conveying of the plate 6.

[0059] Among them, the floating part 3131 adopts a spring rod structure, and its two ends are respectively hinged to the first side plate 312 through hinge seats. The spring rod can swing around the hinge axis within a certain angle range. The spring rod is provided with a torsion spring or a compression spring. The torsion spring or compression spring applies an elastic bias force to the spring rod, so that the scraping edge of the slag removal knife 3132 always keeps abutting against the upper surface of the plate 6.

[0060] When the surface of the sheet material 6 undulates during the conveying process, the spring rod overcomes the elastic bias pressure to generate adaptive oscillation, so that the scraping blade always keeps in contact with the surface of the sheet material; when the undulations disappear, the elastic bias pressure drives the spring rod to return to its original position.

[0061] When the plate 6 is conveyed, the scraping blade of the slag removal knife 3132 scrapes over the punched part of the plate 6, scoops up the debris attached to the edge of the punch, and makes the debris suspend and then sucked away by the negative pressure airflow; the floating part 3131 can adapt to the small undulations on the surface of the plate 6, so that the scraping blade is always in contact with the plate surface, while avoiding rigid contact that scratches the plate 6.

[0062] The first slag removal structure 313 scrapes off the attached debris on the top of the plate 6. Furthermore, in order to reduce the influence of the suction mechanism 32 on the second slag removal structure 333, a second baffle structure 33 is set in front of the suction mechanism 32. The second baffle structure 33 is used to assist in scraping the bottom of the plate 6. A collection groove 34 is set to collect the debris below the plate 6.

[0063] See Figure 3 The second baffle structure 33 and the collection groove 34 are configured and their specific structures are as follows: The second baffle structure 33 is disposed between the first baffle structure 31 and the punching unit 1, and the second baffle structure 33 is disposed below the plate 6.

[0064] See Figure 3 The second baffle structure 33 includes two sets of symmetrically arranged second vertical plates 331 and two sets of symmetrically arranged second side plates 332. The two sides of each set of second vertical plates 331 are fixedly connected to the mounting frame 2, and the installation position of the second baffle structure 33 on the mounting frame 2 is between the punching unit 1 and the first baffle structure 31. The two sets of second side plates 332 are inclined, and the two sides of each set of second side plates 332 are connected to the second vertical plates 331. The two sets of second vertical plates 331 and the two sets of second side plates 332 form a slag removal channel with openings at both ends.

[0065] The specific setup and structure of the second slag removal structure 333 are as follows: See Figure 6 Each set of second side plates 332 has a second slag removal structure 333 on the side near the plate 6. The second slag removal structure 333 has the same structure as the first slag removal structure 313 and the same function, which is to remove the debris attached to the edge of the hole. The scraping blade of the second slag removal structure 333 elastically abuts against the lower surface of the plate 6 and is used to scrape off the debris attached to the punched part during the conveying of the plate 6. The debris scraped by the second slag removal structure 333 falls into the inside of the collection tank 34 under the action of gravity.

[0066] During the slag removal process, the plate 6 first passes through the second baffle structure 33 during the conveying process, and then through the first baffle structure 31 and the suction mechanism 32. The second baffle structure 33 first removes the debris from the edge of the hole on the bottom surface. The debris scraped off by the scraper will fall into the collection tank 34 for removal under the action of gravity. After the bottom surface of the plate 6 is removed by the second baffle structure 33, the plate 6 is conveyed to the position of the first baffle structure 31 and the suction mechanism 32. The first baffle structure 31 and the suction mechanism 32 remove the debris from the top surface of the plate 6.

[0067] In the above-mentioned slag removal process, due to the spatial misalignment of the second baffle structure 33 with the first baffle structure 31 and the suction mechanism 32, the bottom surface is slag removed first, and then the top surface is slag removed. The suction operation of the suction mechanism 32 will not affect the bottom surface slag removal. The spatial misalignment and the bottom-to-top slag removal sequence reduce the interference of negative pressure airflow on the bottom gravity slag falling, which facilitates the normal operation of the slag removal work.

[0068] In addition, the collection space of the collection tank 34 extends from below the perforated unit 1 to below the cleaning component 4, running through the entire descaling process, and can collect the debris that falls off during the process.

[0069] The above structure allows for the extraction and scraping of debris from the top of the plate 6, and the scraping of debris from the bottom of the plate 6, which is then collected by the collection trough 34.

[0070] The specific working process of the slag removal component 3 is as follows: The transmission mechanism drives the plate 6 intermittently forward according to a preset pitch. The plate 6 first enters the punching unit 1. When the plate 6 pauses, the punching unit 1 processes preset mounting holes on the plate 6. After punching is completed, the transmission mechanism starts and conveys the plate 6 to the position of the second baffle structure 33 of the slag removal assembly 3. During the conveying process, the second slag removal structure 333 scrapes and removes the debris from the bottom hole edge of the plate 6. The removed debris falls into the collection tank 34 under the action of gravity for collection.

[0071] After being descaled by the second baffle structure 33, the plate 6 continues to be conveyed to the first baffle structure 31 and the suction mechanism 32. During the conveying process, the negative pressure airflow generated by the suction mechanism 32 sucks out and collects the loose debris on the top surface of the plate 6; at the same time, the descaling blade 3132 on the first side plate 312 scrapes across the surface of the plate, scooping up the firmly attached debris, and completing the top surface cleaning in conjunction with the negative pressure airflow.

[0072] By setting the slag removal component 3 to be spatially staggered, the second baffle structure 33 located below the plate 6 and the first baffle structure 31 located above it, along with the suction mechanism 32, the second slag removal structure 333 scrapes the bottom surface of the plate 6 before the negative pressure is applied and the slag falls into the collection tank 34 by gravity. Then, the first slag removal structure 313 and the suction mechanism 32 work together to remove the top debris and remove it under negative pressure, thus completing the slag removal from the top and bottom of the plate 6.

[0073] In Example 2, the above structure enables the cleaning of debris from the top and bottom of the plate 6. When the punching unit 1 completes punching and the punching mechanism resets, the debris attached to the punching head will remain embedded in the hole. If this debris is not effectively cleaned before roll forming, it will cause the hole opening to crack due to rigid extrusion during subsequent forming, affecting the production quality of the column and further impacting its subsequent use.

[0074] To specifically clean debris from the holes, a debris removal mechanism within the cleaning component 4 is used to remove debris embedded in the holes of the board 6. A bottom-surface brushing mechanism within the cleaning component 4 is also included to clean debris remaining on the bottom surface of the board 6, further cleaning the debris from the board 6. The specific structure of the cleaning component 4 is as follows: See Figure 7 The cleaning component 4 includes a support frame 41, which is a gantry frame structure. It is fixedly installed on the mounting frame 2 by fixing blocks and spans over the conveying path of the plate 6.

[0075] See Figure 7 and Figure 8 The setup and specific structure of the in-hole slag removal mechanism are as follows: The slag removal mechanism is located above the plate 6 and can move vertically to penetrate the punch hole in the plate 6 and remove the debris inside the hole.

[0076] See Figure 7 and Figure 8 The slag removal mechanism inside the hole includes a lifting drive component 43, a mounting plate 45, and four sets of slag removal rods 48.

[0077] The lifting drive component 43 is fixedly installed on the top of the support frame 41, and its output end extends downward through the top of the support frame 41 and is fixedly connected to the mounting plate 45.

[0078] The lifting drive component 43 is a drive cylinder, which is fixedly installed on the top crossbeam of the support frame 41. Its piston rod output end passes downward through the top crossbeam of the support frame 41, and its end is fixedly connected to the horizontally set mounting plate 45.

[0079] Each slag removal rod 48 is fixedly installed at the bottom of the mounting plate 45, and the position of the slag removal rod 48 corresponds to the position of the punch hole on the plate 6. The lower end of the slag removal rod 48 is designed with a tapered structure to facilitate alignment and penetration through the punch hole on the plate 6.

[0080] The setup and specific structure of the bottom slag brushing mechanism are as follows: See Figure 7 and Figure 8 The bottom surface slag brushing mechanism includes a mounting groove 42, a roller brush 47, and a drive motor 46.

[0081] The mounting groove 42 is located in the middle of the support frame 41. The bottom of the mounting groove 42 is fixedly connected to the top of the mounting frame 2. An elastic support pad is arranged around the top opening of the mounting groove 42, and the elastic support pad is inclined towards the inside of the mounting groove 42. The two ends of the roller brush 47 are rotatably mounted in the mounting groove 42 through the connecting shaft. The axis of the roller brush 47 is perpendicular to the conveying direction of the plate 6. The top bristles of the roller brush 47 are in contact with the lower surface of the plate 6. The drive motor 46 is fixedly mounted on one side of the support frame 41, and the output shaft of the drive motor 46 is connected to the connecting shaft of the roller brush 47.

[0082] The specific working process of the in-hole slag removal mechanism is as follows: After the surface of the plate 6 is cleaned by the slag removal component 3, the plate 6 moves forward to the cleaning component 4 area under the drive of the transmission mechanism and stops. At this time, the punch on the plate 6 is vertically aligned with the slag removal rod 48.

[0083] The lifting drive component 43 drives the mounting plate 45 and the slag removal rod 48 vertically downwards. The lower end of the slag removal rod 48 first contacts and penetrates the punched hole in the plate 6, pushing the debris embedded in the hole downwards. During this process, the bristles at the top of the roller brush 47 first contact the lower surface of the plate 6 and generate elastic compression, providing the first level of flexible support. As the slag removal rod 48 continues to press down, after the bristles are compressed to the set stroke, the bottom surface of the plate 6 contacts the elastic support pad. The bristles and the elastic support pad jointly bear the downward pressure, forming the second level of reinforcing support, limiting the deformation of the punched area of ​​the plate, and reducing rigid indentations. The inclined surface of the elastic support pad can guide the swept debris to fall into the mounting groove 42, reducing the possibility of debris accumulating at the groove opening and splashing outwards. Together with the collection groove 34 arranged throughout the area below, the debris can be collected in a controlled manner throughout the process.

[0084] Example 3, see Figure 9The slag removal mechanism in the cleaning component 4 can remove the slag inside the hole. Based on the above structure, in order to reduce the possibility of the slag re-attaching to the plate 6 when the slag removal rod 48 is reset, four sets of annular receiving grooves 471 are distributed circumferentially on the outer periphery of the roller brush 47. The annular receiving grooves 471 are arranged in a ring around the outer side of the roller brush 47, that is, a continuous ring of annular receiving grooves 471 is opened on the outer periphery of the roller brush 47 corresponding to the position of the slag removal rod 48. Each set of annular receiving grooves 471 is equipped with a slag removal brush.

[0085] Furthermore, the radial dimension inside the annular receiving groove 471 is larger than the outer diameter of the slag removal rod 48, and the slag removal rod 48 can extend into the interior of the annular receiving groove 471 under the drive of the lifting drive component 43.

[0086] See Figure 10 The slag-removing brush consists of a bundle of bristles disposed within an annular receiving groove 471. The bristle bundle is fixedly installed on the bottom and wall of the annular receiving groove 471, with the ends of the bristle bundle facing the interior space of the annular receiving groove 471. When the slag-removing rod 48 extends into the annular receiving groove 471, the ends of the bristle bundle contact the outer circumferential surface of the slag-removing rod 48. When the roller brush 47 rotates, the bristle bundle generates friction relative to the outer circumferential surface of the slag-removing rod 48, sweeping away the debris adhering to the surface of the slag-removing rod 48.

[0087] The end of the slag removal rod 48 is designed with a tapered structure to allow it to pass through the punched hole in the plate 6 and enter the interior of the annular receiving groove 471. A gap is maintained between the tapered structure at the end of the slag removal rod 48 and the bottom of the annular receiving groove 471 to avoid rigid interference between them.

[0088] It should be noted that, since the inner size of the annular receiving groove 471 is larger than the outer diameter of the slag removal rod 48, when the slag removal rod 48 is inserted into the annular receiving groove 471, there is a gap between it and the groove wall of the annular receiving groove 471, and the two do not have rigid interference; when the roller brush 47 rotates, the bristles of the slag removal brush sweep the outer circumference of the slag removal rod 48 to complete the removal of slag.

[0089] The process of removing debris from the outer surface of the slag removal rod 48 is as follows: After the plate 6 is cleaned by the slag removal component 3, the plate 6 moves forward to the cleaning component 4 area under the drive of the transmission mechanism and stops. The slag removal rod 48 removes the debris in the hole under the drive of the lifting drive component 43. The slag removal rod 48 continues to move downward and its lower end is inserted into the annular receiving groove 471 on the outer periphery of the roller brush 47. The lower end of the slag removal rod 48 and the bottom of the groove are kept in a gap and do not make rigid contact.

[0090] At this time, drive motor 46 drives roller brush 47 to rotate continuously: The bristles on the surface of the roller brush 47 continuously sweep across the bottom surface of the plate 6, cleaning and removing the debris attached to the bottom surface. The debris falls into the mounting groove 42 below under the action of gravity and is collected. The slag removal brush fixedly installed on the wall of the annular receiving groove 471 rotates synchronously with the roller brush 47. During the rotation, the bristles of the slag removal brush completely remove the debris adhering to the surface of the slag removal rod 48 when it passes through the punch hole.

[0091] After the debris inside the hole is removed and the surface of the slag removal rod 48 is cleaned, the lifting drive component 43 drives the mounting plate 45 and the slag removal rod 48 to move upward and reset, disengaging from the punching hole of the plate 6 and the annular receiving groove 471 of the roller brush 47; then the drive motor 46 controls the roller brush 47 to resume continuous rotation, waiting for the next set of punching holes to be conveyed into place with the plate 6 before repeating the above operation.

[0092] See Figure 7 and Figure 8 Based on the structural design, the cleaning component 4 also includes several guide structures 49 and several support columns 44 to assist in guiding and supporting the movement of the slag removal rod 48. The configuration and specific structure of the guide structures 49 and support columns 44 are as follows: A guide structure 49 is provided between the support frame 41 and the mounting plate 45. The guide structure 49 is used to guide the lifting and lowering movement of the mounting plate 45.

[0093] The guide structure 49 includes a guide rod and a sleeve. The guide rod is fixed in the vertical direction inside the mounting groove 42, and the sleeve is fixedly installed on the mounting plate 45. The sleeve is slidably sleeved on the outside of the guide rod to provide linear guidance for the lifting and lowering movement of the mounting plate 45 and reduce the possibility of horizontal displacement of the slag removal rod 48.

[0094] A number of support columns 44 are provided between the top of the support frame 41 and the mounting groove 42. The top of each support column 44 is fixedly connected to the top of the support frame 41, and the bottom of each support column 44 is fixedly connected to the bottom of the mounting groove 42.

[0095] In this embodiment, four sets of guide structures 49 and four sets of support columns 44 are used. The four sets of guide structures 49 and four sets of support columns 44 are all set on the outside of the plate 6. Their installation positions do not interfere with the conveying of the plate 6. That is, the plate 6 can be conveyed along the middle position of the four sets of guide structures 49 and four sets of support columns 44. Furthermore, since the support columns 44 serve as the overall support, the four sets of support columns 44 are all set on the outside of the four sets of guide structures 49.

[0096] The specific movement process of this device is as follows: The sheet metal 6 first enters the punching unit 1. When the sheet metal 6 is paused, the punching unit 1 processes the preset mounting holes on the sheet metal 6. After punching is completed, the transmission mechanism starts and conveys the sheet metal 6 to the position of the second baffle structure 33 of the slag removal assembly 3. During the conveying process, the second slag removal structure 333 included in the second baffle structure 33 scrapes and removes the debris from the bottom hole edge of the sheet metal 6. The removed debris falls into the collection tank 34 under the action of gravity for collection.

[0097] After being descaled by the second baffle structure 33, the plate 6 continues to be conveyed to the first baffle structure 31 and the suction mechanism 32. During the conveying process, the negative pressure airflow generated by the suction mechanism 32 sucks out and collects the loose debris on the top surface of the plate 6; at the same time, the descaling blade 3132 on the first side plate 312 scrapes across the surface of the plate, scooping up the firmly attached debris, and completing the top surface cleaning in conjunction with the negative pressure airflow.

[0098] The transmission mechanism then continues to drive the plate 6 forward to the cleaning component 4 area and then pauses. At this time, the punch on the plate 6 is vertically aligned with the descaling rod 48.

[0099] Next, the lifting drive 43 drives the mounting plate 45 and the slag removal rod 48 to move vertically downward. The lower end of the slag removal rod 48 first contacts and penetrates the punch hole of the plate 6, pushing the debris embedded in the hole downward. During this process, the roller of the roller brush 47 abuts against the lower surface of the plate 6 through the top bristles, providing bottom support for the punching area, counteracting the downward force generated by the downward movement of the slag removal rod 48, and effectively reducing the risk of local dents or deformation of the plate 6 in the punching area.

[0100] The slag removal rod 48 continues to descend, its lower end inserting into the annular receiving groove 471 on the outer periphery of the roller brush 47, with a gap maintained between the lower end of the slag removal rod 48 and the bottom of the groove, preventing rigid contact between the two. At this time, the drive motor 46 drives the roller brush 47 to rotate continuously.

[0101] The bristles on the surface of the roller brush 47 continuously sweep across the bottom surface of the plate 6, cleaning and removing the debris attached to the bottom surface. The descaling brush rotates synchronously with the roller brush. During the rotation, the descaling brush removes the debris adhering to the surface of the descaling rod 48 when it passes through the punch hole.

[0102] After the debris inside the hole is removed and the surface of the slag removal rod 48 is cleaned, the lifting drive component 43 drives the mounting plate 45 and the slag removal rod 48 to move upward and reset, disengaging from the punching hole of the plate 6 and the annular receiving groove 471 of the roller brush 47; then the drive motor 46 controls the roller brush 47 to resume continuous rotation, waiting for the next set of punching holes to be conveyed into place with the plate 6 before repeating the above operation.

[0103] After the top surface, bottom surface, and inside the hole are thoroughly cleaned, the transmission mechanism is restarted to send the plate 6 into the forming unit 5. The plate 6 is gradually bent by multiple roller sets in the forming unit 5 and finally rolled into a C-shaped shell column 7.

[0104] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
