Description

Technical Field

[0001] The present invention relates to the technical field of metal material processing equipment, in particular to a rectangular flat steel production device. Background Art

[0002] Rectangular flat steel, a common structural metal material, is widely used in a variety of engineering fields, including machinery manufacturing, bridge components, rail transit, and building steel structures. Its processing quality directly affects subsequent welding performance, structural strength, and service life. Therefore, effective surface treatment and performance enhancement are key process steps in the production of rectangular flat steel.

[0003] Existing processing equipment for rectangular flat steel typically provides basic feeding, pressing, and trimming functions, but still has significant shortcomings in surface treatment. For one thing, traditional equipment often relies on manual operation or fixed grinding heads, which can easily lead to problems such as low machining accuracy and surface stress concentration. Furthermore, existing equipment lacks flexibility in adapting to different flat steel sizes and edge treatment, and its relatively simple structure makes it difficult to meet diverse production needs.

[0004] In addition, most current surface treatment methods fail to effectively introduce residual compressive stress control mechanisms, which makes flat steel prone to fatigue cracking or stress corrosion in practical applications, reducing service life and safety performance. To this end, a rectangular flat steel production device is proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a rectangular flat steel production device.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A rectangular flat steel production device includes a processing unit and an auxiliary unit. The auxiliary unit is installed horizontally on the side end face of the processing unit. The processing unit includes a positioning frame and a positioning mechanism installed on both sides of the inner cavity of the positioning frame. Vertical vertical members are vertically arranged at the intervals between the two groups of the positioning mechanisms. The two groups of oppositely arranged vertical vertical members are connected in series through a blocking horizontal plate. Processing mechanisms are horizontally arranged on both sides of the outer end face of the blocking horizontal plate.

[0007] Preferably, the positioning frame includes a frame body and a first connecting frame connected between the two groups of frame bodies, and a second connecting frame is provided on the lower end face of the first connecting frame. The frame body serves as the main frame side wall structure of the overall device, and is symmetrically arranged on the left and right, and is connected and fixed by the first connecting frame through a transverse connecting member to form a closed or semi-closed frame outline structure; a second connecting frame is provided on the lower end face of the first connecting frame for installing functions such as positioning or material passing channels, so that the overall frame has the dual functions of structural support and functional extension.

[0008] The three together constitute the basic outer frame unit of this device, providing the load-bearing foundation and positioning reference of the overall structure, ensuring that the device has good structural rigidity, stability and centering during operation, and providing a standard reference surface for the installation of internal processing components.

[0009] Preferably, the positioning mechanism comprises a vertical shaft and a sliding stopper sleeved onto the outer ring of the vertical shaft. A carrier plate is provided at the other end of the vertical shaft, and a first insert is inserted into the inner cavity of the carrier plate. One end of the rectangular flat steel to be processed is laterally inserted between two roller-type sliding stoppers within the device and the carrier plate. The sliding stopper can slide up and down around the vertical axis of its outer end wall as a fulcrum, thereby automatically adjusting the gap based on the thickness of the flat steel. After sliding adjustment is completed, the bottom of the sliding stopper abuts against the upper end surface of the flat steel, forming a compact positioning structure.

[0010] Preferably, the vertical uprights include two groups of second inserts installed in the inner cavity of the frame, and limiting rings are installed on the inner sides of the two groups of second inserts. The two groups of limiting rings are connected in series through the installation vertical rods. The component assembly consisting of the second inserts, the limiting rings and the installation vertical rods is vertically installed in the middle position of the inner cavity of the frame to constitute the central axis positioning structure of the device. Its vertical structural layout divides the internal space into functions. The two groups of vertical uprights are located on both sides of the middle positioning structure, and the horizontal plate is blocked by a connecting piece to form a series and partition relationship with the middle structure, thereby dividing the overall processing device into two relatively independent processing areas.

[0011] This structural design allows the two processing mechanisms, located on either side, to operate independently, separated by a barrier plate to prevent interference. Specifically, each processing mechanism can be adapted to process rectangular flat steel of varying specifications and process requirements, effectively enhancing the equipment's parallel processing capabilities and structural flexibility.

[0012] Preferably, the processing mechanism includes a processing frame and an inner processing groove opened in the inner cavity of the processing frame, a driving cylinder is vertically arranged on both sides of the inner cavity of the inner processing groove, and multiple groups of the processing frames arranged horizontally are connected by connecting cross bars. The gaps between the inner processing grooves of the multiple groups of processing frames are connected in series horizontally through contact limit cross bars. The gap between the carrier plate and the vertical axis is highly consistent with the opening position of the inner processing groove. One end of the rectangular flat steel continues to slide horizontally into the internal channel of the inner processing grooves of the multiple processing components. The inner processing groove forms a linearly arranged sliding guide groove, and the inner cavity space is slightly larger than the size of the flat steel, allowing it to pass with less friction. The driving cylinder is externally connected to a driving motor, and the rotation of the driving motor drives the driving cylinder to perform continuous and rhythmic impact processing on the outer surface of the flat steel.

[0013] During machining, impact loads generate a compressive stress field centered on the flat steel surface, placing the machined layer under pressure. After the impact, the surface material's rebound is limited, forming a stable residual compressive stress distribution that enhances fatigue and stress corrosion resistance. By applying rhythmic impact loads to the rectangular flat steel surface, plastic deformation is induced, and a stable residual compressive stress layer forms after unloading. This compressive stress distribution helps improve the flat steel's fatigue and stress corrosion resistance, significantly extending its service life and stability.

[0014] Multiple groups of processing mechanisms are arranged linearly. Driven by an external control system, multiple groups of drive cylinders can achieve synchronous impact or intermittent rhythmic impact. Multiple drive cylinder components act on multiple positions on the flat steel surface at the same frequency and phase at the same time, realizing large-area, synchronous impact processing. Multiple points are loaded at the same time to form a continuous and consistent residual compressive stress field, reducing stress concentration. Multiple parts are processed at the same time, which is suitable for high-speed production lines or continuous processing of large flat steel parts. Uniform stress distribution can reduce warping and internal stress imbalance caused by single-point concentrated impact.

[0015] The impact head is loaded periodically at time intervals, or impacts different positions in a rhythmic rotation, resulting in gradual advancement of local processing areas. Strengthening treatment can be implemented in specific areas such as corners, hole peripheries, heat-affected zones, etc., to improve flexibility and help form a gradient strength structure. It is suitable for functionally gradient flat steel or components with uneven force distribution. Residual stress distribution at different depths and directions can be designed according to the processing rhythm to improve multi-dimensional crack resistance.

[0016] Preferably, the auxiliary unit includes an adjustment mechanism and a limit adjustment mechanism installed on the inner end surface of the adjustment mechanism, the adjustment mechanism includes a clamping member and a mounting frame installed on the outer end surfaces of the upper and lower groups of clamping members, the intervals of the mounting frames are connected in series through swing arms, and the auxiliary unit arranged on one side of the processing unit is interspersed, the adjustment mechanism is a curved support frame, the swing arm arranged on it can rotate and swing with its two ends as fulcrums, and the limit adjustment mechanism can pass through the processing mechanism on one side to support the outer end wall of the blocking horizontal plate.

[0017] The rectangular flat steel to be processed is flipped horizontally 90 degrees so that its originally non-processed side wall is converted into the current upper surface or the guide surface of the processing direction, thereby realizing precise positioning processing of surfaces in different directions. One end of the flat steel is introduced through the positioning guide rail and inserted horizontally along the path into the inner cavity processing groove of multiple sets of processing mechanism impact components.

[0018] Preferably, a limit adjustment mechanism is installed on the inner end faces of the two groups of swing arms, and the limit adjustment mechanism includes two groups of load-bearing plates and springs installed at the intervals between the two groups of load-bearing plates. Mounting parts are relatively provided at the four corners of the edges of the two groups of load-bearing plates, and the two opposite groups of mounting parts are connected in series through a connecting rod. During the processing of rectangular flat steel, the staff can push and pull the swing arm horizontally to make the swing arm swing and rotate with the two groups of mounting frames connected to it as the fulcrum. This swinging action drives the two groups of load-bearing plates to move as a whole, and through the matching structure of the mounting part and the connecting rod, they swing slightly relative to the spring under the allowable space constraints. The micro-swing structure causes the limit sleeve installed between the two groups of load-bearing plates to adjust its posture accordingly, thereby changing the fitting angle and clamping position of the inner end wall below it and the edge of the rectangular flat steel, thereby realizing flexible adaptation and clamping positioning of the workpiece at different processing angles.

[0019] Through the staff's lateral push-pull operation of the swing arm, the micro-posture of the rectangular flat steel in the scene can be flexibly adjusted, and the operation steps are simplified. Through the lever-type swing structure with the mounting frame as the fulcrum, combined with the linkage angle adjustment mechanism between the mounting parts, connecting rods, and springs, dynamic matching of the clamping position and the angle is achieved, which effectively improves the adaptability of the device to rectangular flat steels of different sizes or different processing surface states, ensuring that it can still maintain a stable clamping state during multi-angle processing, ensuring the coordination and consistency of clamping and guiding during the grinding process, and avoiding processing errors or edge damage.

[0020] Preferably, both ends of the connecting rod can be telescopically adjusted with two sets of mounting parts as fulcrums, both ends of the spring are connected to the inner end surfaces of the two sets of bearing plates, and the maximum adjustment angle of the spring is 90 degrees.

[0021] Preferably, the limit adjustment mechanism also includes a limit sleeve connected between the two sets of bearing plates at the outer ends. This limit sleeve is connected to the outer ring of the contact limit rod through the connecting crossbar on the other side of the blocking crossbar. The limit sleeve is located at a specific position in the equipment, and its lower inner end wall can precisely fit over the processing area of ​​the flat steel edge. When the equipment is in operation, the two sets of contact limit rods clamp on both sides of the flat steel to be processed, playing a critical role in limiting and guiding, ensuring the initial stability of the flat steel's position. At the same time, the internal processing groove also conforms to the surface of the flat steel, providing additional clamping effect and further strengthening the flat steel's fixation in the equipment. In addition, the operator applies lateral thrust to the swing arm to guide the flat steel's position and fine-tune its position, thereby ensuring the flat steel's stability throughout the entire movement process. With this synergistic effect, the adjustment mechanism, limit adjustment mechanism, and processing mechanism work together with the flat steel to form multiple points of support, achieving a three-point contact state, ensuring that the flat steel is always stably positioned during the operation of the external grinding equipment. At this time, with such overall coordination, the limiting sleeve can smoothly and accurately carry out processing operations on the processing parts of the flat steel edge, ensuring the quality and precision of the processing.

[0022] Compared with the prior art, the present invention has the following beneficial effects: 1. The device of the present invention constructs a multi-point support and clamping structure through the coordinated cooperation between the main frame assembly, the end auxiliary processing assembly and multiple groups of processing components. In particular, the processing mechanism, the limit adjustment mechanism and the limit sleeve jointly realize the limit guidance and three-point clamping of the rectangular flat steel during the processing process, which can effectively prevent the workpiece from deflecting or shaking during the impact processing, and improve the stability and accuracy of the processing.

[0023] 2. The impact structure driving cylinder in the device of the present invention acts on the processing surface of the rectangular flat steel through rhythmic impact loading, generating residual compressive stress distribution on its surface, improving the metal grain structure, and enhancing its fatigue resistance and stress corrosion resistance, thereby significantly extending the service life and service stability of the rectangular flat steel.

[0024] 3. The various structures of the device of the present invention adopt a combination of series connection, sliding connection, and limit, which has good modular characteristics and can be quickly adjusted according to different processing requirements, such as multi-faceted clamping, edge processing, non-load-bearing surface rotation positioning and other functions. It can adapt to rectangular flat steels of different specifications or structures, effectively improving the scope of application and operating efficiency of the equipment.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figures 1-8, Example 1, a rectangular flat steel production device, including a processing unit 1 and an auxiliary unit 2, the auxiliary unit 2 is horizontally installed on the side end face of the processing unit 1, the processing unit 1 includes a positioning frame 11 and a positioning mechanism 12 installed on both sides of the inner cavity of the positioning frame 11, a vertical vertical member 13 is vertically arranged at the interval between the two groups of the positioning mechanism 12, the two groups of oppositely arranged vertical vertical members 13 are connected in series through a blocking horizontal plate 14, and processing mechanisms 15 are horizontally arranged on both sides of the outer end face of the blocking horizontal plate 14.

[0028] The positioning frame 11 includes a frame body 111 and a first connecting frame 112 connected between the two groups of frame bodies 111. A second connecting frame 113 is provided on the lower end face of the first connecting frame 112. The frame body 111 serves as the main frame side wall structure of the overall device and is symmetrically arranged on the left and right. The frame body 111 is connected and fixed by a transverse connecting member, the first connecting frame 112, to form a closed or semi-closed frame outline structure. A second connecting frame 113 is provided on the lower end face of the first connecting frame 112 for installing functions such as positioning or material passages, so that the overall frame has the dual functions of structural support and functional extension.

[0029] The three together constitute the basic outer frame unit of this device, providing the load-bearing foundation and positioning reference of the overall structure, ensuring that the device has good structural rigidity, stability and centering during operation, and providing a standard reference surface for the installation of internal processing components.

[0030] In Example 2, the positioning mechanism 12 includes a vertical shaft 121 and a sliding stopper 122 sleeved onto the outer ring of the vertical shaft 121. A carrier plate 123 is provided at the other end of the vertical shaft 121. A first insert 124 is inserted into the inner cavity of the carrier plate 123. One end of the rectangular flat steel to be processed is laterally inserted between the two roller sliding stoppers 122 and the carrier plate 123 within the device. The sliding stopper 122 can slide up and down around its outer end wall, using the vertical shaft 121 as a fulcrum, thereby automatically adjusting the gap based on the thickness of the flat steel. After the sliding adjustment is completed, the bottom of the sliding stopper 122 abuts against the upper end surface of the flat steel, forming a compact positioning structure.

[0031] The vertical uprights 13 include two groups of second inserts 131 installed through the inner cavity of the frame 111, and the inner sides of the two groups of second inserts 131 are installed with limiting rings 132. The two groups of limiting rings 132 are connected in series through the installation vertical rod 133. The component assembly consisting of the second inserts 131, the limiting rings 132 and the installation vertical rod 133 is vertically installed in the middle position of the inner cavity of the frame 111, forming the central axis positioning structure of the device. Its vertical structural layout divides the internal space into functions. The two groups of vertical uprights 13 are arranged on both sides of the middle positioning structure, and are connected by a connecting member to block the horizontal plate 14 to form a series and partition relationship with the middle structure, thereby dividing the overall processing device into two relatively independent processing areas.

[0032] This structural design allows the two processing mechanisms 15, located on either side, to operate independently, separated by a barrier plate 14 to prevent interference with each other's processing. Specifically, the two processing mechanisms 15 can each be adapted to process rectangular flat steel of different specifications and with different process requirements, effectively enhancing the equipment's parallel processing capabilities and structural flexibility.

[0033] In Example 3, the processing mechanism 15 includes a processing frame 151 and an inner processing groove 152 located within the inner cavity of the processing frame 151. Drive cylinders 153 are vertically positioned on both sides of the inner cavity of the inner processing groove 152. Multiple sets of processing frames 151 arranged transversely are connected by connecting cross bars 154. The gaps between the inner processing grooves 152 of the multiple sets of processing frames 151 are connected in series transversely via contact limiting cross bars 155. The gaps between the carrier plate 123 and the vertical axis 121 are highly consistent with the openings of the inner processing grooves 152. One end of the rectangular flat steel continues to slide transversely into the internal channels of the inner processing grooves 152 of the multiple processing components. The inner processing grooves 152 form linearly arranged sliding guides, with the inner cavity space slightly larger than the size of the flat steel, allowing it to pass through with minimal friction. The drive cylinder 153 is externally connected to a drive motor, which rotates to drive the drive cylinder 153 to perform continuous, rhythmic impact processing on the outer surface of the flat steel.

[0034] During machining, impact loads generate a compressive stress field centered on the flat steel surface, placing the machined layer under pressure. After the impact, the surface material's rebound is limited, forming a stable residual compressive stress distribution that enhances fatigue and stress corrosion resistance. By applying rhythmic impact loads to the rectangular flat steel surface, plastic deformation is induced, and a stable residual compressive stress layer forms after unloading. This compressive stress distribution helps improve the flat steel's fatigue and stress corrosion resistance, significantly extending its service life and stability.

[0035] In embodiment 4, multiple groups of processing mechanisms 15 are arranged linearly, and multiple groups of driving cylinders 153 are driven by an external control system to realize synchronous impact or intermittent rhythmic impact. Multiple driving cylinder 153 components act on multiple positions on the flat steel surface at the same frequency and phase at the same time, realizing large-area, synchronous impact processing. Multiple points are loaded at the same time to form a continuous and consistent residual compressive stress field, reducing stress concentration. Multiple parts are processed at the same time, which is suitable for high-speed production lines or continuous processing of large flat steel parts. Uniform stress distribution can reduce warping and internal stress imbalance caused by single-point concentrated impact.

[0036] The impact head is loaded periodically at time intervals, or impacts different positions in a rhythmic rotation, resulting in gradual advancement of local processing areas. Strengthening treatment can be implemented in specific areas such as corners, hole peripheries, heat-affected zones, etc., to improve flexibility and help form a gradient strength structure. It is suitable for functionally gradient flat steel or components with uneven force distribution. Residual stress distribution at different depths and directions can be designed according to the processing rhythm to improve multi-dimensional crack resistance.

[0037] Example 5, the auxiliary unit 2 includes an adjustment mechanism 21 and a limit adjustment mechanism 22 installed on the inner end surface of the adjustment mechanism 21, the adjustment mechanism 21 includes a clamping member 211 and a mounting frame 212 installed on the outer end surfaces of the upper and lower groups of clamping members 211, the intervals of the mounting frames 212 are connected in series through swing arms 213, and the auxiliary unit 2 is interspersed on one side of the processing unit 1, the adjustment mechanism 21 is a curved support frame, and the swing arm 213 provided thereon can rotate and swing with its two ends as fulcrums, and the limit adjustment mechanism 22 can pass through the processing mechanism 15 on one side to support the outer end wall of the blocking horizontal plate 14.

[0038] The rectangular flat steel to be processed is flipped horizontally 90 degrees so that its originally non-processed side wall is converted into the current upper surface or the processing direction guide surface, thereby realizing precise positioning processing of surfaces in different directions. One end of the flat steel is introduced through the positioning guide rail and inserted horizontally along the path into the inner cavity processing groove 152 of the impact component of multiple sets of processing mechanisms 15.

[0039] In embodiment 6, the inner end surfaces of the two groups of swing arms 213 are installed with a limit adjustment mechanism 22, and the limit adjustment mechanism 22 includes two groups of bearing plates 221 and a spring 222 installed at the interval between the two groups of bearing plates 221. The four corners of the edges of the two groups of bearing plates 221 are relatively provided with mounting parts 223. The two groups of mounting parts 223 are connected in series through a connecting rod 224. During the processing of the rectangular flat steel, the staff can push and pull the swing arm 213 horizontally, so that the swing arm 213 can be adjusted by the two groups connected by it. The mounting frame 212 is a fulcrum that causes a swinging rotation, and this swinging action drives the two sets of supporting plates 221 to move as a whole. Through the matching structure of the mounting member 223 and the connecting rod 224, a slight angle swing occurs relative to the spring 222 under the allowable space constraint. This micro-swing structure causes the limiting sleeve 225 installed between the two sets of supporting plates 221 to also adjust its posture, thereby changing the fitting angle and clamping position of the inner end wall below it and the edge of the rectangular flat steel, thereby achieving flexible adaptation and clamping positioning of the workpiece at different processing angles.

[0040] Example 7, through the staff's lateral push-pull operation of the swing arm 213, flexible adjustment of the micro-posture of the rectangular flat steel in the scene is achieved, and the operating steps are simplified. Through the lever-type swing structure with the mounting frame 212 as the fulcrum, combined with the linkage angle adjustment mechanism between the mounting part 223, the connecting rod 224, and the spring 222, dynamic matching of the clamping position and the angle is achieved, which effectively improves the adaptability of the device to rectangular flat steels of different sizes or different processing surface states, ensures that it can still maintain a stable clamping state during multi-angle processing, ensures the coordination and consistency of clamping and guiding during the grinding process, and avoids processing errors or edge damage.

[0041] In Example 8, the two ends of the connecting rod 224 can be telescopically adjusted with two sets of mounting parts 223 as fulcrums. The two ends of the spring 222 are connected to the inner end faces of the two sets of bearing plates 221. The maximum adjustment angle of the spring 222 is 90 degrees. The limit adjustment mechanism 22 also includes a limit sleeve 225 connected between the two sets of bearing plates 221 at the outer ends. The limit sleeve 225 is connected through the connecting cross bar 154 on the other side of the blocking cross plate 14 and the outer ring of the contact limit cross bar 155. The limit sleeve 225 is located at a specific position of the equipment, and the inner end wall below it can accurately fit on the part to be processed on the edge of the flat steel. When the equipment is in operation, the two sets of contact limit cross bars 155 will be clamped on both sides of the flat steel to be processed, playing a key role in limiting and guiding, ensuring the initial stability of the position of the flat steel. At the same time, the inner processing groove 152 will also fit on the surface of the flat steel to achieve an additional clamping effect on the flat steel, further enhancing the fixation of the flat steel in the equipment. In addition, the staff applies a lateral thrust to the swing arm 213 to guide the flat steel to fine-tune its posture, thereby ensuring the flat steel's stability throughout the entire movement process. Under such synergistic action, the adjustment mechanism 21, the limit adjustment mechanism 22, and the processing mechanism 15 work together with the flat steel to form a multi-point support and achieve a three-point contact state, so that the flat steel is always in a stable position when the external grinding equipment is working.

[0042] At this time, with such overall cooperation, the limiting sleeve 225 can smoothly and accurately carry out processing operations on the processing part of the flat steel edge, ensuring the quality and accuracy of the processing.

[0043] To summarize, one end of the rectangular flat steel to be processed is inserted horizontally between two roller-type sliding stoppers 122 and a carrier plate 123 within the device. Sliding stoppers 122 can slide up and down around their outer end walls, using a vertical axis 121 as a fulcrum, automatically adjusting the gap based on the thickness of the flat steel. After adjustment, the bottom of sliding stoppers 122 abuts against the upper surface of the flat steel, forming a compacting and positioning structure.

[0044] After insertion, one end of the rectangular flat steel bar continues to slide horizontally into the internal channels of the multiple processing components' internal processing slots 152. These internal processing slots 152 form linearly arranged sliding guides, with the internal cavity slightly larger than the flat steel bar, allowing it to pass through with minimal friction. A drive cylinder 153 is externally connected to a drive motor, which rotates to drive the drive cylinder 153, continuously and rhythmically impacting the flat steel bar's outer surface.

[0045] During machining, impact loads generate a compressive stress field centered on the flat steel surface, placing the machined layer under pressure. After the impact, the surface material's rebound is limited, forming a stable residual compressive stress distribution that enhances fatigue and stress corrosion resistance. By applying rhythmic impact loads to the rectangular flat steel surface, plastic deformation is induced, and a stable residual compressive stress layer forms after unloading. This compressive stress distribution helps improve the flat steel's fatigue and stress corrosion resistance, significantly extending its service life and stability.

[0046] In addition, multiple groups of processing mechanisms 15 are arranged linearly, and under the drive of an external control system, multiple groups of drive cylinders 153 can realize synchronous impact or intermittent rhythmic impact. Multiple drive cylinder 153 components act on multiple positions on the flat steel surface at the same frequency and phase at the same time, realizing large-area, synchronous impact processing. Multiple points are loaded at the same time to form a continuous and consistent residual compressive stress field, reducing stress concentration. Multiple parts are processed at the same time, which is suitable for high-speed production lines or continuous processing of large flat steel parts. Uniform stress distribution can reduce warping and internal stress imbalance caused by single-point concentrated impact.

[0047] The impact head is loaded periodically at time intervals, or impacts different positions in a rhythmic rotation, resulting in gradual advancement of local processing areas. Strengthening treatment can be implemented in specific areas such as corners, hole peripheries, heat-affected zones, etc., to improve flexibility and help form a gradient strength structure. It is suitable for functionally gradient flat steel or components with uneven force distribution. Residual stress distribution at different depths and directions can be designed according to the processing rhythm to improve multi-dimensional crack resistance.

[0048] Furthermore, the rectangular flat steel to be processed is flipped 90 degrees laterally so that its originally non-processed side wall is converted into the current upper surface or the processing direction guide surface, thereby achieving precise positioning processing of surfaces in different directions. One end of the flat steel is introduced through the positioning guide rail and inserted laterally along the path into the inner cavity processing groove 152 of the impact assembly of the multiple processing mechanisms 15; The limiting sleeve 225 is located in a specific position within the machine, with its lower inner end wall precisely aligned with the area of ​​the flat steel edge to be processed. When the machine is operating, two sets of contact limiting crossbars 155 clamp onto either side of the flat steel to be processed, providing a crucial position-limiting guide and ensuring the initial stability of the flat steel's position. Simultaneously, the internal processing groove 152 also conforms to the surface of the flat steel, providing additional grip and further securing it within the machine.

[0049] Furthermore, by applying lateral thrust to the swing arm 213, the operator guides the flat steel to fine-tune its position, thereby ensuring its stability throughout the entire motion process. Under this synergistic effect, the adjustment mechanism 21, the limit adjustment mechanism 22, and the processing mechanism 15 work together with the flat steel to form multi-point support and achieve a three-point contact state, ensuring that the flat steel remains stably positioned while being polished by the external grinding equipment. At this time, the limit sleeve 225, with this integrated coordination, can smoothly and accurately perform processing operations on the processing area of ​​the flat steel edge, ensuring processing quality and precision.

[0050] Furthermore, during the processing of rectangular flat steel, the staff can push and pull the swing arm 213 horizontally, so that the swing arm 213 can swing and rotate with the two sets of mounting frames 212 connected to it as the fulcrum. This swinging action drives the two sets of supporting plates 221 to move as a whole. Through the matching structure of the mounting part 223 and the connecting rod 224, a slight angle swing occurs relative to the spring 222 under the allowable space constraint. The micro-swing structure causes the limiting sleeve 225 installed between the two sets of supporting plates 221 to also adjust its posture accordingly, thereby changing the fitting angle and clamping position of the inner end wall below it and the edge of the rectangular flat steel, thereby realizing flexible adaptation and clamping positioning of the workpiece at different processing angles.

[0051] Specifically, through the staff's lateral push-pull operation of the swing arm 213, flexible adjustment of the micro-posture of the rectangular flat steel in the scene is achieved, and the operating steps are simplified. Through the lever-type swing structure with the mounting frame 212 as the fulcrum, combined with the linkage angle adjustment mechanism between the mounting part 223, the connecting rod 224, and the spring 222, dynamic matching of the clamping position and the angle is achieved, which effectively improves the adaptability of the device to rectangular flat steels of different sizes or different processing surface states, ensures that it can still maintain a stable clamping state during multi-angle processing, ensures the coordination and consistency of clamping and guiding during the grinding process, and avoids processing errors or edge damage.

[0052] The component assembly consisting of the second insert 131, the limiting ring 132 and the mounting vertical rod 133 is vertically installed in the middle position of the inner cavity of the frame 111, forming the central axis positioning structure of the device. Its vertical structural layout divides the internal space into functions. The two groups of vertical vertical members 13 are arranged on both sides of the middle positioning structure, and are connected in series and separated by the connecting member to form a series and partition relationship with the middle structure, thereby dividing the overall processing device into two relatively independent processing areas.

[0053] The above is the entire working principle of the present invention.

[0054] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated on.

[0055] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.

[0056] In the present invention, unless otherwise specified, directional words contained in terms such as "up, down, left, right, front, back, inside, outside, and vertical, horizontal" only represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term. At the same time, number series nouns such as "first", "second" and "third" do not represent specific quantities and orders, but are merely used to distinguish names. Moreover, the terms "include", "comprise" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
