Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal material processing equipment, and particularly relates to a rectangular flat steel production device. BACKGROUND

[0002] As a common structural metal material, the rectangular flat steel is widely used in many engineering fields such as mechanical manufacturing, bridge components, rail transportation and building steel structure. The processing quality of the rectangular flat steel directly affects the subsequent welding performance, structural strength and service life. Therefore, in the production and manufacturing process of the rectangular flat steel, effective treatment and performance strengthening of the surface thereof become one of the key process steps.

[0003] The existing processing device of the rectangular flat steel usually has basic feeding, pressing and edge cutting functions, but still has obvious deficiencies in surface strengthening treatment. On the one hand, the traditional device relies on manual operation or fixed grinding head for processing, which is easy to cause low processing precision, surface stress concentration and other problems; on the other hand, the existing device lacks flexibility in adapting to flat steels of different sizes and in treating edge parts, and the device structure is relatively single, which is difficult to meet diversified production needs.

[0004] In addition, most of the current surface treatment methods cannot effectively introduce a residual compressive stress control mechanism, which causes the flat steel to easily produce fatigue cracks or stress corrosion in actual application, thereby reducing the service life and safety performance. Therefore, a rectangular flat steel production device is proposed. SUMMARY

[0005] The purpose of the present application is to solve the problems existing in the prior art and provide a rectangular flat steel production device.

[0006] In order to achieve the above purpose, the present application adopts the following technical scheme:

[0007] A rectangular flat steel production device comprises a processing unit and an auxiliary unit, the side end surface of the processing unit is transversely installed with the auxiliary unit, the processing unit comprises a positioning frame and positioning mechanisms installed on both sides of the inner cavity of the positioning frame, vertical vertical pieces are vertically arranged at intervals between the two groups of positioning mechanisms, and the two groups of oppositely arranged vertical vertical pieces are connected through a blocking horizontal plate, and the outer end surface of the blocking horizontal plate is transversely provided with a processing mechanism on both sides.

[0008] Preferably, the positioning frame comprises a frame body and a first connecting frame connected between the two groups of frame bodies, a second connecting frame is formed in the lower end surface of the first connecting frame, the frame body serves as the main frame side wall structure of the whole device, is symmetrically arranged left and right, is connected and fixed through the transverse connecting piece first connecting frame, constitutes a closed or semi-closed frame contour structure, and the first connecting frame is provided with the second connecting frame in the lower end surface, which is used for installing positioning or material passage and the like, so that the whole frame has the dual functions of structural support and functional extension.

[0009] The three together constitute the basic frame unit of the device, providing the load-bearing base and positioning reference of the overall structure, ensuring good structural rigidity, stability and centring during operation, and providing a standard reference surface for the installation of internal processing components.

[0010] Preferably, the positioning mechanism includes a vertical shaft and a sliding limiting block fitted on the outer circle of the vertical shaft, the other end of the vertical shaft is provided with a bearing disc, the inner cavity of the bearing disc is provided with a first insert, and one end of the rectangular flat steel to be processed is inserted horizontally between the two roller sliding limiting blocks and the bearing disc provided in the device. The sliding limiting block can slide up and down around the vertical shaft as the fulcrum of the outer end wall, thereby automatically adjusting the gap according to the thickness of the flat steel. After the sliding adjustment is completed, the bottom of the sliding limiting block is in contact with the upper end surface of the flat steel, forming a pressing and positioning structure.

[0011] Preferably, the vertical uprights include two groups of second inserts installed in the inner cavity of the frame, the inner sides of the two groups of second inserts are provided with limiting rings, the two groups of limiting rings are connected by installation vertical rods, the component assembly composed of the second inserts, limiting rings and installation vertical rods is vertically installed at the middle position of the inner cavity of the frame, constituting the central positioning structure of the device, and the vertical structural layout divides the internal space into two parts. The two groups of vertical uprights are arranged on both sides of the middle positioning structure, and the connecting member separates the cross plate from the middle structure to form a series connection and a blocking relationship, thereby dividing the overall processing device into two relatively independent processing areas.

[0012] This structural design allows the two groups of processing mechanisms arranged on both sides to work independently and be blocked by the blocking cross plate to avoid interference with each other during processing. Specifically, the two groups of processing mechanisms can be used to process rectangular flat steels of different specifications and different process requirements, effectively improving the parallel processing capacity and structural flexibility of the equipment.

[0013] Preferably, the processing mechanism includes a processing frame and an internal processing groove opened at a position in the inner cavity of the processing frame, driving cylinders are vertically arranged at both sides of the inner cavity of the internal processing groove, a plurality of groups of processing frames arranged horizontally are connected by link cross bars, the internal processing grooves of the plurality of groups of processing frames are horizontally connected in series by contact limiting cross bars, the gap between the bearing disc and the vertical shaft is at the same height as the opening position of the internal processing groove, and one end of the rectangular flat steel continues to slide horizontally into the internal passage of the internal processing groove of the plurality of processing assemblies. The internal processing groove forms a linearly arranged sliding guide groove, the inner cavity space is slightly larger than the size of the flat steel, allowing it to pass through with less friction, and the driving cylinder is externally connected with a driving motor, which rotates to drive the driving cylinder to continuously and rhythmically impact process the outer surface of the flat steel.

[0014] The impact load generates a compressive stress field centered on the surface of the flat steel during the machining process, causing the machined layer to be in a compressed state. When the impact ends, the surface layer material is limited in resilience, forming a stable residual compressive stress distribution, enhancing the fatigue resistance and stress corrosion resistance. By applying rhythmic impact load to the surface of the rectangular flat steel, plastic deformation of the surface layer material is induced and a stable residual compressive stress layer is formed after unloading. This compressive stress distribution helps to improve the fatigue resistance and stress corrosion resistance of the flat steel, thereby significantly prolonging its service life and service stability.

[0015] The multiple sets of machining mechanisms are linearly arranged and driven by an external control system to realize synchronous impact or intermittent rhythmic impact. Multiple drive cylinder assemblies simultaneously act on multiple positions on the surface of the flat steel at the same frequency and phase, realizing large-area synchronous impact machining. Multiple point loads form a continuous and consistent residual compressive stress field, reducing stress concentration. Multiple parts are processed simultaneously, which is suitable for high-speed production lines or continuous machining of large flat steel parts. Uniform stress distribution can reduce warping and internal stress imbalance caused by single-point concentrated impact.

[0016] The impact head is periodically loaded at time intervals, or different positions are impacted in a rhythmic rotation, gradually advancing the local processing area. It can be used for strengthening processing of specific areas such as corners, hole perimeters, and heat-affected zones, improving flexibility and helping to form a gradient strength structure. It is suitable for functionally graded flat steel or components with uneven stress distribution. It can design residual stress distribution of different depths and directions according to the processing rhythm to improve multi-dimensional crack resistance.

[0017] Preferably, the auxiliary unit includes an adjusting mechanism and a limiting adjustment mechanism mounted on the end face of the adjusting mechanism. The adjusting mechanism includes clamping pieces and mounting frames mounted on the outer end faces of the upper and lower clamping pieces. The mounting frames are connected by swing arms at intervals and are arranged in the auxiliary unit on one side of the machining unit. The adjusting mechanism is a curved support frame, and the swing arms arranged thereon can rotate and swing with their two ends as fulcrums. The limiting adjustment mechanism can support the outer end wall of the blocking plate on one side of the machining mechanism.

[0018] The rectangular flat steel to be machined is turned 90 degrees horizontally, so that its original non-machining side wall is converted into the current upper surface or machining direction guide surface, thereby realizing accurate positioning and machining of the surface in different directions. One end of the flat steel is introduced through the positioning guide rail and inserted horizontally into the inner cavity of the machining groove of the impact assembly of the multiple sets of machining mechanisms.

[0019] Preferably, the inner end faces of the two sets of swing arms are provided with limiting adjustment mechanisms, the limiting adjustment mechanisms comprising two sets of bearing plates and springs installed at intervals between the two sets of bearing plates, and opposite corners of the edges of the two sets of bearing plates are provided with mounting members, and the opposite two sets of mounting members are connected by connecting rods in series. During the processing of the rectangular flat steel, the swing arms can be pushed and pulled horizontally by the workers, so that the swing arms swing around the two sets of mounting frames connected thereto as fulcrums. This swinging action drives the two sets of bearing plates to move as a whole. Through the cooperation of the mounting members and the connecting rods, the two sets of bearing plates can swing slightly in angle relative to the springs within the allowed space. The micro-swing structure enables the limiting sleeve members installed between the two sets of bearing plates to adjust their postures, so as to change the fitting angle and clamping position of the inner end walls below the limiting sleeve members with the edges of the rectangular flat steel, thereby realizing the flexible adaptation and clamping positioning of the workpiece at different processing angles.

[0020] Through the horizontal pushing and pulling operation of the swing arms by the workers, the flexible adjustment of the micro-posture of the rectangular flat steel in the scene is realized, the operation steps are simplified, and through the lever-type swinging structure with the mounting frames as fulcrums, the linkage angle adjustment mechanism among the mounting members, the connecting rods and the springs is combined to realize the dynamic matching of the clamping position and the clamping angle, thereby effectively improving the adaptation ability of the device to rectangular flat steels of different sizes or different processing surface states, ensuring that the rectangular flat steels can still maintain a stable clamping state during multi-angle processing, guaranteeing the coordination consistency of clamping and guiding during polishing, and avoiding processing errors or edge damage.

[0021] Preferably, the two ends of the connecting rod can be adjusted in length with the two sets of mounting members as fulcrums, the two ends of the spring are connected to the inner end faces of the two sets of bearing plates, and the maximum adjustment angle of the spring is 90 degrees.

[0022] Preferably, the limiting adjustment mechanism further comprises a limiting sleeve connector connected between the two groups of bearing sheets at the outer end, the limiting sleeve connector is sleeved through the abutting cross rod on the other side of the blocking cross plate and the outer ring of the contact limiting cross rod, and the limiting sleeve connector is located at a specific position of the device, and the inner end wall below can be accurately attached to the to-be-processed part of the edge of the flat steel. When the device is in operation, the two groups of contact limiting cross rods are clamped on both sides of the to-be-processed flat steel respectively, and play a key role in limiting and guiding, so as to ensure the initial stability of the position of the flat steel. At the same time, the inner machining groove is also attached to the surface of the flat steel, realizing the additional clamping effect of the flat steel, and further enhancing the fixation of the flat steel in the device. In addition, the worker guides the flat steel to fine-tune the posture by applying a transverse thrust to the swing arm, so as to ensure the stability of the flat steel in the whole movement process. Under the synergistic effect, the adjusting mechanism, the limiting adjustment mechanism and the machining mechanism jointly act on the flat steel to form a multi-point support, so that the flat steel is in a three-point contact state, so that the flat steel is always in a stable positioning state when subjected to the work of the external polishing device. At this time, the limiting sleeve connector is smoothly and accurately machined on the machining part of the edge of the flat steel under the cooperation of the whole, so as to ensure the quality and precision of the machining.

[0023] Compared with the prior art, the beneficial effects of the present application are:

[0024] 1. The device of the present application cooperates with the main frame assembly, the end auxiliary machining assembly and the plurality of machining assemblies to form a multi-point support clamping structure, especially through the cooperation of the machining mechanism, the limiting adjustment mechanism and the limiting sleeve connector to realize the limiting and guiding of the rectangular flat steel during the machining process and the three-point clamping, which can effectively prevent the workpiece from deviating or shaking during impact machining, and improve the stability and precision of the machining.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments.

[0039] The positioning frame 11 comprises 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 formed in 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 left and right, connected and fixed through the transverse connecting piece first connecting frame 112, and constitutes a closed or semi-closed frame contour structure; the first connecting frame 112 is provided with a second connecting frame 113 in the lower end face, which is used for installing positioning or material passage and the like, so that the overall frame has the dual functions of structural support and functional extension.

[0040] The three together constitute the basic outer frame unit of the device, provide the load-bearing basis and positioning reference of the overall structure, ensure that the device has good structural rigidity, stability and centration during operation, and provide a standard reference surface for the installation of internal processing components.

[0041] Embodiment 2, the positioning mechanism 12 comprises a vertical shaft 121 and a sliding limiting block 122 sleeved on the outer circle of the vertical shaft 121, a bearing disc 123 is formed in the other end of the vertical shaft 121, a first insert 124 is inserted into the inner cavity of the bearing disc 123, and one end of the rectangular flat steel to be processed is transversely inserted between the two roller sliding limiting blocks 122 and the bearing disc 123 arranged in the device. The sliding limiting block 122 can slide up and down around the vertical shaft 121 as the fulcrum of the outer end wall, so as to automatically adjust the gap according to the thickness of the flat steel. After the sliding adjustment is completed, the bottom of the sliding limiting block 122 is attached to the upper end face of the flat steel, forming a pressing positioning structure.

[0042] The vertical vertical piece 13 comprises two groups of second inserts 131 inserted into the inner cavity of the frame body 111, a limiting ring 132 is installed on the inner side of the two groups of second inserts 131, and the two groups of limiting rings 132 are connected in series through a mounting vertical rod 133. The component assembly composed of the second insert 131, the limiting ring 132 and the mounting vertical rod 133 is vertically installed at the middle position of the inner cavity of the frame body 111, constituting the central positioning structure of the device, and the vertical structure layout divides the internal space into functions. The two groups of vertical vertical pieces 13 are arranged on both sides of the middle positioning structure, and the connecting piece blocking horizontal plate 14 and the middle structure form a series connection and blocking relationship, so as to divide the overall processing device into two relatively independent processing areas.

[0043] The structure design enables two groups of machining mechanisms 15 arranged on both sides to work independently, and the blocking plate 14 forms a block to avoid interference with each other during machining. Specifically, the two groups of machining mechanisms 15 can be respectively applied to machining rectangular flat steels with different specifications and different process requirements, effectively improving the parallel machining capability and structural flexibility of the equipment.

[0044] In embodiment 3, the machining mechanism 15 comprises a machining frame 151 and an inner machining groove 152 arranged in the inner cavity position of the machining frame 151. A driving cylinder 153 is arranged vertically at both sides of the inner cavity of the inner machining groove 152. A plurality of groups of machining frames 151 are arranged transversely and connected by a connecting cross bar 154. The inner machining grooves 152 of the plurality of groups of machining frames 151 are transversely connected in series by a contact limiting cross bar 155. The gap position between the bearing disc 123 and the vertical shaft 121 is consistent with the arrangement position of the inner machining groove 152. One end of the rectangular flat steel continuously slides into the inner passage of the inner machining groove 152 of the plurality of machining assemblies. The inner machining groove 152 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 153 is connected with a driving motor. The driving motor rotates to drive the driving cylinder 153 to continuously and rhythmically impact the outer surface of the flat steel.

[0045] The impact load generates a compressive stress field centered on the surface of the flat steel during the machining process, so that the machining layer is in a compressed state. After the impact ends, the surface layer material is limited in resilience, forming a stable residual compressive stress distribution, enhancing the fatigue resistance and stress corrosion resistance. By applying a rhythmic impact load to the surface of the rectangular flat steel, plastic deformation of the surface layer material is induced and a stable residual compressive stress layer is formed after unloading. The compressive stress distribution helps to improve the fatigue resistance and stress corrosion resistance of the flat steel, thereby significantly prolonging its service life and service stability.

[0046] In embodiment 4, a plurality of groups of machining mechanisms 15 are arranged linearly and driven by an external control system to realize synchronous impact or intermittent rhythmic impact of the plurality of groups of driving cylinders 153. The plurality of driving cylinder 153 assemblies simultaneously act on multiple positions on the surface of the flat steel at the same frequency and phase, realizing large-area and synchronous impact machining. Multiple points are loaded simultaneously to form a continuous and consistent residual compressive stress field, reducing stress concentration. Multiple parts are processed simultaneously, which is suitable for high-speed production lines or continuous machining of large flat steel parts. Uniform stress distribution can reduce warping and unbalanced internal stress caused by single-point concentrated impact.

[0047] The impact head is periodically loaded at time intervals, or different positions are impacted in rhythm, so that the local processing area gradually advances, and the specific area can be subjected to intensive processing such as corners, hole periphery, heat-affected zone, etc., improving flexibility and helping to form a gradient strength structure, which is suitable for functionally graded flat steel or components with uneven stress distribution, and can design residual stress distribution of different depths and different directions according to the processing rhythm to improve multi-dimensional crack resistance.

[0048] In the embodiment 5, the auxiliary unit 2 comprises an adjusting mechanism 21 and a limiting adjusting mechanism 22 installed on the end face of the adjusting mechanism 21. The adjusting mechanism 21 comprises clamping pieces 211 and a mounting frame 212 installed on the outer end faces of the upper and lower groups of clamping pieces 211. The mounting frame 212 is connected in series through swing arms 213 at intervals. The auxiliary unit 2 is arranged on one side of the processing unit 1. The adjusting mechanism 21 is a curved support frame. The swing arms 213 arranged thereon can rotate and swing with the two ends as fulcrums. The limiting adjusting mechanism 22 can support the outer end wall of the blocking transverse plate 14 through one side of the processing mechanism 15.

[0049] The rectangular flat steel to be processed is turned over by 90 degrees horizontally, so that the original non-processing side wall is converted into the current upper surface or processing direction guide surface, so as to realize accurate positioning and processing of the surface in different directions. One end of the flat steel is guided into the processing groove 152 in the inner cavity of the impact assembly of the multiple groups of processing mechanisms 15 along the path.

[0050] In the embodiment 6, the inner end faces of the two groups of swing arms 213 are provided with limiting adjusting mechanisms 22. The limiting adjusting mechanism 22 comprises two groups of bearing pieces 221 and springs 222 installed at intervals between the two groups of bearing pieces 221. The edges of the two groups of bearing pieces 221 are provided with mounting pieces 223 at the positions of the four corners. The two groups of mounting pieces 223 are connected in series through connecting rods 224. During the processing of the rectangular flat steel, the swing arms 213 can be pushed and pulled horizontally by the workers, so that the swing arms 213 swing and rotate with the two groups of mounting frames 212 connected thereto as fulcrums. The swing action drives the two groups of bearing pieces 221 to move integrally. Through the cooperation of the mounting pieces 223 and the connecting rods 224, the two groups of bearing pieces 221 can slightly swing at a small angle relative to the springs 222 within the allowed space. The micro-swing structure makes the limiting sleeve piece 225 installed between the two groups of bearing pieces 221 adjust the posture, so as to change the fitting angle and clamping position of the inner end wall below the limiting sleeve piece 225 and the edge of the rectangular flat steel, and realize flexible adaptation and clamping positioning of the workpiece at different processing angles.

[0051] In the embodiment 7, the staff can adjust the posture of the rectangular flat steel by pushing and pulling the swing arm 213, which simplifies the operation steps. The lever swing structure with the mounting frame 212 as the fulcrum, combined with the linkage angle adjustment mechanism among the mounting member 223, the connecting rod 224 and the spring 222, can realize the dynamic matching of the clamping position and angle, effectively improve the adaptability of the device to rectangular flat steels of different sizes or different processing surface states, ensure stable clamping state in multi-angle processing, ensure the coordination of clamping and guiding in the polishing process, and avoid processing errors or edge damage.

[0052] In the embodiment 8, the two ends of the connecting rod 224 can be adjusted in extension and retraction with the two groups of mounting members 223 as fulcrums. The two ends of the spring 222 are connected to the inner end faces of the two groups of bearing sheets 221. The maximum adjustment angle of the spring 222 is 90 degrees. The limiting sleeve member 225 is connected between the two groups of bearing sheets 221 at the outer end. The limiting sleeve member 225 is sleeved through the outer circle of the contact limiting cross rod 155 on the other side of the blocking cross plate 14 and the connecting cross rod 154. The limiting sleeve member 225 is located at a specific position of the device, and the inner end wall below it can accurately fit on the edge of the flat steel to be processed. When the device is in operation, the two groups of contact limiting cross rods 155 will be clamped on both sides of the flat steel to be processed, playing a key limiting and guiding role to ensure 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, realizing additional clamping effect of the flat steel, and further enhancing the fixation of the flat steel in the device. In addition, the staff can guide the fine posture adjustment of the flat steel by applying a lateral thrust to the swing arm 213, so as to ensure the stability of the flat steel in the whole movement process. Under such synergistic action, the adjusting mechanism 21, the limiting adjustment mechanism 22 and the processing mechanism 15 work together with the flat steel to form multi-point support, achieving a three-point contact state, so that the flat steel is always in a stable positioning state when subjected to the work of the external polishing device.

[0053] At this time, the limiting sleeve member 225 can smoothly and accurately process the processing part of the edge of the flat steel under the overall cooperation, ensuring the quality and precision of the processing.

[0054] In summary: one end of the rectangular flat steel to be processed is inserted horizontally between the two roller sliding limiting blocks 122 and the bearing disc 123 arranged in the device. The sliding limiting block 122 can slide up and down around the vertical shaft 121 at the outer end wall as the fulcrum, so as to realize automatic adjustment of the gap according to the thickness of the flat steel. After the sliding adjustment is completed, the bottom of the sliding limiting block 122 is in contact with the upper end face of the flat steel, forming a compression positioning structure.

[0055] After the insertion is completed, one end of the rectangular flat steel continues to slide horizontally into the inner channel of the plurality of processing assemblies. The inner processing groove 152 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, and the driving cylinder 153 is externally connected with a driving motor, which rotates to drive the driving cylinder 153 to continuously and rhythmically impact the outer surface of the flat steel.

[0056] The impact load generates a compressive stress field centered on the surface of the flat steel during processing, causing the processed layer to be in a compressed state. When the impact ends, the surface layer material is limited in resilience, forming a stable residual compressive stress distribution, enhancing fatigue resistance and stress corrosion resistance. By applying rhythmic impact load to the surface of the rectangular flat steel, plastic deformation of the surface layer material is induced and a stable residual compressive stress layer is formed after unloading. This compressive stress distribution helps to improve the fatigue resistance and stress corrosion resistance of the flat steel, thereby significantly extending its service life and service stability.

[0057] In addition, the plurality of processing mechanisms 15 are linearly arranged and driven by the external control system to achieve synchronous impact or intermittent rhythmic impact. The plurality of driving cylinders 153 components simultaneously act on multiple positions on the surface of the flat steel at the same frequency and phase, achieving large-area synchronous impact processing. Multiple points are loaded simultaneously to form a continuous and consistent residual compressive stress field, reducing stress concentration. Multiple parts are processed simultaneously, suitable for high-speed production lines or large-scale flat steel continuous processing. Uniform stress distribution can reduce warping and unbalanced internal stress caused by single-point concentrated impact.

[0058] The impact head is periodically loaded at time intervals, or different positions are impacted in a rhythmic rotation, producing a gradual advancement of the local processing area. It can be used for strengthening processing of specific areas such as corners, hole circumferences, and heat-affected zones, improving flexibility and helping to form a gradient strength structure. It is suitable for functional gradient flat steel or components with uneven stress distribution. Different depths and directions of residual stress distribution can be designed according to the processing rhythm to improve multi-dimensional crack resistance.

[0059] Further, the rectangular flat steel to be processed is flipped 90 degrees horizontally, so that its original non-processing side wall is converted into the current upper surface or processing direction guide surface, thereby achieving accurate positioning and processing of different direction surfaces. One end of the flat steel is guided into the inner cavity of the plurality of processing mechanisms 15 impact assemblies through the positioning guide rail, and is inserted horizontally along the path into the inner processing groove 152.

[0060] The limiting sleeve joint 225 is located at a specific position of the device, and the inner end wall below it can accurately fit on the edge of the rectangular steel to be processed. When the device is in operation, the two sets of contact limiting cross bars 155 will be clamped on both sides of the rectangular steel to be processed, playing a key role in limiting and guiding, ensuring the initial stability of the position of the rectangular steel. At the same time, the inner processing groove 152 will also fit on the surface of the rectangular steel, achieving additional clamping effect of the rectangular steel, further enhancing the fixation of the rectangular steel in the device.

[0061] In addition, the staff adjusts the posture of the rectangular steel by applying a lateral thrust to the swing arm 213, thereby ensuring the stability of the rectangular steel during the entire movement. Under such synergistic action, the adjusting mechanism 21, the limiting adjustment mechanism 22 and the processing mechanism 15 work together with the rectangular steel to form multi-point support, achieving a three-point contact state, so that the rectangular steel is always in a stable positioning state when it is subjected to the work of the external polishing device. At this time, the limiting sleeve joint 225 can smoothly and accurately process the processing part of the edge of the rectangular steel under the overall cooperation, ensuring the quality and precision of the processing.

[0062] Further, during the processing of the rectangular steel, the staff can perform lateral push-pull operation on the swing arm 213, so that the swing arm 213 swings around the two sets of mounting frames 212 connected thereto as the fulcrum, and the two sets of bearing plates 221 are driven to swing as a whole. Through the cooperation of the mounting member 223 and the connecting rod 224, the bearing plates 221 can slightly swing relative to the spring 222 within the allowable space constraint, and the limiting sleeve joint 225 mounted between the two sets of bearing plates 221 can 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 steel, realizing flexible adaptation and clamping positioning of the workpiece at different processing angles.

[0063] Specifically, through the lateral push-pull operation of the staff on the swing arm 213, the flexible adjustment of the posture of the rectangular steel in the scene is realized, and the operation steps are simplified. Through the lever-type swing structure with the mounting frame 212 as the fulcrum, combined with the linkage angle adjustment mechanism among the mounting member 223, the connecting rod 224 and the spring 222, the dynamic matching of the clamping position and the clamping angle is realized, which effectively improves the adaptation ability of the device to rectangular steels of different sizes or different processing surface states, ensures that the rectangular steel can still maintain a stable clamping state during multi-angle processing, guarantees the coordination consistency of clamping and guiding during polishing, and avoids processing errors or edge damage.

[0064] The component assembly composed of the second insert 131, the limiting ring 132 and the mounting vertical rod 133 is vertically mounted in the middle position of the inner cavity of the frame body 111, and constitutes the middle axis positioning structure of the device.
