Description

Technical Field

[0001] This invention relates to the field of steel structure component processing technology, specifically to a continuous processing device for steel structure components. Background Technology

[0002] In the continuous processing of steel structural components, especially H-shaped steel structural components, continuous processing devices such as integrated welding and straightening machines are often used. During the straightening operation, the position of the straightening rollers relative to the steel directly determines the straightening effect and the processing quality of the steel structural components.

[0003] Existing straightening roller position adjustment technologies are mainly divided into two types: manual adjustment and electric preset adjustment. However, manual adjustment relies heavily on the operator's experience, which is not only time-consuming and labor-intensive, but also makes it difficult to ensure the consistency of adjustment accuracy between different batches or different positions of steel in the same batch. Although preset adjustment can be automatically adjusted and avoids the time-consuming and labor-intensive nature of manual adjustment and the problem of consistency, in actual production, due to the thickness tolerance, plate warping, or dimensional changes caused by thermal expansion and contraction of the steel itself, the actual surface position of the steel often deviates from the theoretical position.

[0004] The existing fixed stroke adjustment method cannot sense the actual contact state of the steel, making it difficult to accurately control the contact pressure between the straightening roller and the steel. If the reserved gap is too large, it may lead to insufficient straightening force or slippage; if the downward pressure is too large, it may cause over-straightening and damage to the steel surface. Therefore, it is necessary to propose a continuous processing device for steel structural components to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a continuous processing device for steel structural components, which solves the problem that preset adjustment methods are difficult to accurately control the contact pressure between the straightening roller and the steel.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a continuous processing device for steel structural components, comprising a frame, a welding assembly adjustablely installed on one side of the frame, a platform fixedly installed at the bottom of the frame, and a conveying roller frame disposed on one side of the frame, wherein an adjustment assembly is symmetrically installed on the top of the platform, and a detection assembly is installed on one side of the adjustment assembly; The adjustment assembly includes a horizontal adjustment component and a vertical adjustment component mounted on the horizontal adjustment component. A straightening roller is rotatably mounted on the vertical adjustment component.

[0009] Preferably, one end of the straightening roller's shaft is rotatably mounted on one side of the mounting plate via a bearing. The mounting plate has a right-angle structure and is fixed to the side of the vertical slider facing the wing plate and its adjacent side via an extension slider. A cleaning component is fixedly connected to one side of the mounting plate, and a protective component is fixedly mounted on the other side of the mounting plate.

[0010] Preferably, the detection roller includes a clamping plate, an inner rotating cylinder, an electric slip ring, a pressure sensor, a flexible transition layer, a rigid heat insulation layer, and an elastic force transmission layer; The clamping plate is fixedly installed on one side of the mounting frame. One end of the rotating shaft of the inner rotating cylinder is rotatably installed inside the clamping plate on one side, and the other end of the rotating shaft of the inner rotating cylinder is fixedly connected to the inner wall of the rotor of the electric slip ring. The stator of the electric slip ring is fixedly installed inside the other side of the clamping plate. The pressure sensors are multiple and are staggered on the outer wall of the inner rotating cylinder. The connecting wires of the pressure sensors are electrically connected to the rotor end of the slip ring. The stator end of the slip ring is connected to an external controller via a signal line to output the detection signal of the pressure sensor. The pressure sensor is attached to the outer wall of the inner rotating cylinder. The flexible transition layer is sleeved on the outer wall of the inner rotating cylinder and covers the outside of the pressure sensor. The pressure sensor is a thin-film pressure sensor.

[0011] Preferably, the rigid heat insulation layer is tightly fitted onto the outer wall of the flexible transition layer, and the elastic force transmission layer is wrapped around the outer wall of the rigid heat insulation layer. The rotors of the pressure sensor, flexible transition layer, rigid heat insulation layer, elastic force transmission layer, and electric slip ring are arranged to rotate with the inner rotating cylinder. The lower surface of the elastic force transmission layer and the lower surface of the straightening roller are at the same horizontal height in the working state.

[0012] Preferably, the internal structure of the second detection roller is the same as that of the first detection roller. The detection assembly also includes an infrared temperature sensor, which is fixedly installed on one side of the clamping plate. The infrared detection line of the infrared temperature sensor is located near the first detection roller and is vertically arranged on the top of the wing plate.

[0013] Preferably, the protective assembly includes an electric push rod, a connecting block, a sliding column, a crankshaft, a sliding groove, a rotating shaft, a fixing plate, and a mounting block; The electric push rod is fixedly installed on one side of the mounting plate, and the connecting block is fixedly installed at the bottom end of the telescopic rod of the electric push rod.

The sliding groove is opened on the outside of the crankshaft, and the sliding column is slidably arranged inside the sliding groove.

The mounting block is fixedly connected to the outer wall of the rotating shaft, and the mounting bracket is fixedly installed on one side of the mounting block.

[0014] Preferably, the slide groove has an arc-shaped structure, and the telescopic rod of the electric push rod extends to drive the slide column to move vertically downward. The slide column slides along the arc-shaped trajectory of the slide groove. Through the cooperation between the slide column and the slide groove, the crankshaft is driven to rotate the rotating shaft and the mounting bracket by ninety degrees.

[0015] Preferably, the cleaning assembly includes a connecting bracket and a cleaning brush; The connecting frame is fixedly installed on one side of the mounting plate, and the cleaning brush is fixedly installed on the connecting frame with its bottom flush with the bottom of the first detection roller. The cleaning brush moves up and down synchronously with the straightening roller and is made of ceramic fiber material.

[0016] Working principle: When the steel enters the straightening station, the adjustment component first drives the detection component to move, so that detection roller 2 and detection roller 1 respectively come into contact with the edge and top of the steel wing plate. During this process, the built-in pressure sensor monitors the pressure change of the contact interface in real time and transmits the generated vertical and horizontal pressure detection signals to the control system.

[0017] After receiving the signal, the control system performs calculations based on the preset process pressure threshold and outputs control commands to drive the adjustment components. The adjustment components adjust the displacement of the horizontal and vertical adjustment components accordingly, thereby driving the straightening roller to move until the pressure value detected by the sensor stabilizes within the preset range, thus achieving precise adaptive positioning of the straightening roller.

[0018] Once positioning is complete, the protective assembly retracts the detection assembly to one side, removing it from the high-temperature steel surface to prevent the pressure sensor from being damaged by prolonged heating. Simultaneously, the infrared temperature sensor detects the steel surface temperature, dynamically adjusting the pressure detection threshold to eliminate the influence of temperature on detection accuracy. Furthermore, the cleaning assembly is placed before the straightening roller and the detection assembly to clean the welding slag in the straightening and detection areas in advance, avoiding any impact on straightening quality and detection accuracy.

[0019] This invention provides a continuous processing apparatus for steel structural components. It has the following beneficial effects: 1. This invention uses detection roller one and detection roller two to abut the top and edge of the wing plate respectively, and uses internal pressure sensors to detect vertical and horizontal pressure signals in real time. The displacement of the straightening roller is dynamically controlled by the adjustment component according to the pressure signals, which improves the adaptability of the contact pressure between the straightening roller and the steel structure. This not only avoids the tediousness of manual adjustment, but also solves the problem that fixed stroke adjustment cannot adapt to workpiece errors, thereby improving the straightening automation level and positioning accuracy of the continuous processing device.

[0020] 2. By incorporating a protective component, this invention allows the detection component to be driven to move to one side and detach from the wing plate surface after completing its detection and positioning. This effectively prevents the pressure sensor from being damaged by residual heat due to prolonged exposure to high-temperature steel, thus increasing the lifespan of the pressure sensor. Simultaneously, in conjunction with an infrared temperature sensor, the system can intelligently adjust the pressure detection threshold based on the actual temperature of the steel surface, thereby achieving temperature compensation. This ensures the accuracy of pressure detection data under high-temperature conditions, prevents misjudgments caused by temperature, and further improves the positioning accuracy of the straightening roller.

[0021] 3. By adding a cleaning brush between the straightening roller and the first inspection roller, the welding slag and impurities attached to the straightening and inspection areas can be removed in a timely manner. This prevents welding slag from entering the bottom of the straightening roller and being pressed into the steel surface, thus affecting the straightening quality of the straightening roller, or entering the bottom of the first inspection roller and affecting the inspection accuracy of the first inspection roller. Pre-cleaning ensures the stability of the continuous processing device during long-term operation. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see the appendix Figure 1 - Appendix Figure 10 This invention provides a continuous processing device for steel structural components, including a frame 1, a welding assembly 2 adjustablely installed on one side of the frame 1, a platform 3 fixedly installed at the bottom of the frame 1, and a conveying roller frame 9 arranged on one side of the frame 1. An adjustment assembly 4 is symmetrically installed on the top of the platform 3, and a detection assembly 6 is installed on one side of the adjustment assembly 4. The adjustment component 4 includes a horizontal adjustment component and a vertical adjustment component mounted on the horizontal adjustment component. A straightening roller 5 is rotatably mounted on the vertical adjustment component. The detection component 6 includes a mounting frame 61, a first detection roller 62 and a second detection roller 64 rotatably mounted on one side of the mounting frame 61. The mounting frame 61 is fixedly mounted on the vertical adjustment component. Pressure sensors 624 are installed inside both the first detection roller 62 and the second detection roller 64. Detection roller 62 and detection roller 64 abut against the top and edge of the wing plate respectively, and the pressure sensor 624 inside them generates vertical and horizontal pressure detection signals respectively; the adjustment component 4 responds to the pressure detection signals and controls the displacement of the vertical adjustment component and the horizontal adjustment component respectively to determine the corresponding use position of the straightening roller 5. After the flanges and webs of the H-beam steel structure are assembled and limited by the assembly mechanism on one side of the upright frame 1, they are conveyed to the top of the platform 3 by the conveying mechanism. The contact position of the flanges and webs is welded by the welding assembly 2. At the same time, the flanges are straightened by the straightening rollers 5 that abut against the side of the flanges. Specifically, the conveying mechanism moves the welded steel structure, so that the straightening rollers 5 that abut against the top of the flanges roll. Since the straightening rollers 5 have an eccentric structure, their eccentricity is small, usually within 5 mm, to avoid excessive straightening force that could cause excessive damage to the flanges. The straightening rollers 5 repeatedly apply pressure to straighten the flanges, thereby avoiding the flanges from warping due to welding heat. The welded and straightened H-beam steel structure is then conveyed to the next processing stage by the conveying roller frame 9. Specifically, when the position of the straightening roller 5 needs to be adjusted according to the width and thickness of the wing plate of the steel structure component, the horizontal use position of the straightening roller 5 is first positioned by the detection roller 2 64 to adapt to different widths of the wing plate. Then, the vertical use direction of the straightening roller 5 is positioned by the detection roller 1 62 to adapt to different thicknesses of the wing plate. Finally, after the position of the straightening roller 5 is determined, the detection component 6 is rotated to one side away from the wing plate surface by the protective component 7, thereby avoiding the high temperature residual heat from affecting the normal use of the pressure sensor 624. The initial use positions of the horizontal adjustment component and the vertical adjustment component are the horizontal slider 42 at the far left and the vertical slider 46 at the top, respectively, to avoid affecting the passage of wider or thicker wing plates in the initial adjustment stage.

[0026] Please see the appendix Figure 4 and attached Figure 7 The horizontal adjustment component includes a horizontal drive motor 40, a horizontal lead screw 41, a horizontal slider 42, a connecting plate 43, and a housing 44. The horizontal lead screw 41 is fixedly connected to one end of the output shaft of the horizontal drive motor 40. The horizontal slider 42 is threadedly installed on the outside of the horizontal lead screw 41. The housing 44 is located outside the horizontal lead screw 41 and the horizontal slider 42. The horizontal drive motor 40 is fixedly installed on one side of the housing 44, and the horizontal lead screw 41 is rotatably installed inside the housing 44. The horizontal slider 42 is slidably disposed inside the outer casing 44. An extension block is provided on the top of the horizontal slider 42, and the extension block is fixedly connected to the bottom of the connecting plate 43. A sliding opening is provided on the top of the outer casing 44 corresponding to the extension block, and the extension block is slidably disposed in the sliding opening. Specifically, when the straightening roller 5 is positioned by the second detection roller 64, the horizontal drive motor 40 is turned on to rotate in the forward direction, causing the horizontal drive motor 40 to drive the horizontal lead screw 41 to rotate inside the outer casing 44. This moves the horizontal slider 42 to move the outer casing 45 towards the wing plate side through the top connecting plate 43 until the second detection roller 64 abuts against the edge of the wing plate. At this time, the pressure sensor 624 inside the second detection roller 64 is squeezed and generates a change in pressure value, which is transmitted through the signal line. After conversion and analysis, it is determined whether the pressure value has reached the set value. If the pressure on the pressure sensor 624 is within the set threshold, it indicates that the straightening roller 5 has moved to the appropriate position on the wing plate, completing the horizontal position adjustment of the straightening roller 5.

[0027] Please see the appendix Figure 5 Appendix Figure 7 Appendix Figure 8 and attached Figure 10The vertical adjustment component includes a second housing 45, a vertical slider 46, a mounting plate 47, a vertical lead screw 48, and a vertical drive motor 49. The second housing 45 is fixedly installed on the top of the connecting plate 43. The vertical slider 46 is slidably disposed inside the second housing 45. An extension slider is provided on the side of the vertical slider 46 facing the wing plate and its adjacent side. The second housing 45 has a through groove corresponding to the extension slider, and the extension slider is slidably disposed inside the through groove. Mounting plate 47 is fixedly connected to one side of extension slider, vertical lead screw 48 is rotatably installed inside housing 2 45, and vertical lead screw 48 is threadedly installed inside vertical slider 46, vertical drive motor 49 is fixedly installed on the top of housing 2 45, and the output shaft of vertical drive motor 49 is fixedly connected to the top of vertical lead screw 48. The clamping plate 621 is fixedly installed on one side of the mounting bracket 61. One end of the rotating shaft of the inner rotating cylinder 622 is rotatably installed inside the clamping plate 621, and the other end of the rotating shaft of the inner rotating cylinder 622 is fixedly connected to the inner wall of the rotor of the electric slip ring 623. The stator of the electric slip ring 623 is fixedly installed inside the other side of the clamping plate 621. There are multiple pressure sensors 624, which are staggered on the outer wall of the inner rotating cylinder 622. The connecting wires of the pressure sensors 624 are electrically connected to the rotor end of the electric slip ring 623. The stator end of the electric slip ring 623 is connected to an external controller through a signal line to output the detection signal of the pressure sensor 624. The pressure sensor 624 is attached to the outer wall of the inner rotating cylinder 622. The flexible transition layer 625 is sleeved on the outer wall of the inner rotating cylinder 622 and covers the outside of the pressure sensor 624. The pressure sensor 624 is a thin-film pressure sensor.

[0028] The rigid heat insulation layer 626 is tightly fitted onto the outer wall of the flexible transition layer 625, and the elastic force transmission layer 627 is wrapped around the outer wall of the rigid heat insulation layer 626. The rotors of the pressure sensor 624, the flexible transition layer 625, the rigid heat insulation layer 626, the elastic force transmission layer 627, and the electric slip ring 623 are arranged to rotate with the inner rotating cylinder 622. The lower surface of the elastic force transmission layer 627 and the lower surface of the straightening roller 5 are at the same horizontal height in the working state. The internal structure of the second detection roller 64 is the same as that of the first detection roller 62. The detection assembly 6 also includes an infrared temperature sensor 63, which is fixedly installed on one side of the clamping plate 621. The infrared detection line of the infrared temperature sensor 63 is located near the first detection roller 62 and is vertically arranged on the top of the wing plate. Specifically, after adjusting the horizontal position of the straightening roller 5 using the second detection roller 64, the horizontal drive motor 40 is turned off and the vertical drive motor 49 is started. This causes the vertical drive motor 49 to rotate forward, driving the vertical lead screw 48 to rotate and causing the vertical slider 46 to move downward inside the second housing 45. This causes the mounting plate 47 on the outside of the second housing 45 to move the detection assembly 6 downward. At this time, the second detection roller 64, due to its contact relationship with the edge of the wing plate, rolls along the edge of the wing plate during the downward movement and naturally disengages from the edge. Simultaneously, the first detection roller 62 is pressed down and abuts against the top of the side of the wing plate. At this time, the elastic force transmission layer 627 abuts against the top of the wing plate and squeezes the rigid heat insulation layer 626 and the flexible transition layer 625 to transmit pressure to the internal pressure sensor 624. The pressure sensor 624 detects the pressure received during the downward movement. When the detected pressure is at the set threshold, the use of the vertical drive motor 49 is stopped, thereby positioning the straightening roller 5 at the top of the side of the wing plate and completing the vertical position adjustment of the straightening roller 5. The rigid heat insulation layer 626 can be made of high-temperature resistant ceramic or high-temperature resistant alloy material, which is responsible for blocking heat conduction and withstanding mechanical extrusion. The flexible transition layer 625 can be made of extremely thin silicone pad, fluororubber film or polyurethane elastic film, which is used to fill the space between the pressure sensor 624 and the rigid heat insulation layer 626 to avoid damage to the pressure sensor 624 caused by hard extrusion. At the same time, it improves the wrapping and pre-tightening effect, ensuring that the pressure sensor 624, the flexible transition layer 625, the rigid heat insulation layer 626 and the elastic force transmission layer 627 can rotate synchronously with the inner rotating drum 622. When the wing plate is moved by the conveyor roller frame 9, the detection roller 1 62 and the detection roller 2 64 can roll on the top and one side of the wing plate respectively to detect pressure.

[0029] Please see the appendix Figure 6 Appendix Figure 8 and attached Figure 9 One end of the shaft of the straightening roller 5 is rotatably mounted on one side of the mounting plate 47 via a bearing. The mounting plate 47 has a right-angle structure and is fixed to the side of the vertical slider 46 facing the wing plate and its adjacent side via an extension slider. A cleaning component 8 is fixedly connected to one side of the mounting plate 47, and a protective component 7 is fixedly mounted on the other side of the mounting plate 47. An electric push rod 71 is fixedly installed on one side of the mounting plate 47, and a connecting block 72 is fixedly installed at the bottom end of the telescopic rod of the electric push rod 71. A sliding column 73 is fixedly connected to one side of the connecting block 72. A sliding groove 75 is opened on the outside of the crankshaft 74. The sliding column 73 is slidably disposed inside the sliding groove 75. The crankshaft 74 is fixedly connected to the bottom end of the rotating shaft 76. A fixing plate 77 is fixedly installed on one side of the mounting plate 47, and the rotating shaft 76 is rotatably installed inside the fixing plate 77. A mounting block 78 is fixedly connected to the outer wall of the rotating shaft 76, and a mounting bracket 61 is fixedly installed on one side of the mounting block 78. The slide 75 has an arc-shaped structure. The telescopic rod of the electric push rod 71 extends to drive the slide column 73 to move vertically downward. The slide column 73 slides along the arc-shaped trajectory of the slide 75. Through the cooperation of the slide column 73 and the slide 75, the crankshaft 74 is driven to rotate the rotating shaft 76 and the mounting bracket 61 by ninety degrees. The connecting bracket 81 is fixedly installed on one side of the mounting plate 47. The cleaning brush 82 is fixedly installed on the connecting bracket 81, and its bottom is flush with the bottom of the detection roller 62. The cleaning brush 82 moves up and down synchronously with the straightening roller 5. The cleaning brush 82 is made of ceramic fiber material. After the positioning of the straightening roller 5 is completed, the electric push rod 71 is activated, causing the telescopic rod of the electric push rod 71 to push the connecting block 72 downward, causing the sliding column 73 to move vertically downward. Since the slide groove 75 is an arc groove, when the sliding column 73 slides inside the slide groove 75, it forces the crankshaft 74 to drive the rotating shaft 76 to rotate inside the fixed plate 77. At the same time, the mounting block 78 drives the mounting frame 61 to rotate ninety degrees, thereby moving the detection roller 1 62 and the detection roller 2 64 away from the surface of the wing plate, avoiding the detection roller 1 62 and the detection roller 2 64 from continuously rolling on one side of the wing plate, which would cause the welding residual heat to damage the pressure sensor 624. When the next steel structure part of different size is continuously processed, the horizontal drive motor 40 and the vertical drive motor 49 are reversed to return to the initial position, and the electric push rod 71 is pulled upward to pull the sliding column 73 to make the rotating shaft 76 drive the detection component 6 to reset. Then the straightening roller 5 can be automatically adjusted again to suit wing plates of different widths and thicknesses. Optionally, an infrared temperature sensor 63 is set on one side of the detection roller 62. When the detection roller 62 rolls on the top of the wing plate to detect pressure, the infrared temperature sensor 63 detects the residual temperature of the wing plate at the detection roller 62. The measured temperature can be used as a reference value to set the threshold of the pressure sensor 624. For example, when the temperature is high, the hardness of the steel is lower, so the pressure threshold can be appropriately reduced. This allows for flexible adjustment of the downward pressure of the detection roller 62 and the straightening roller 5, avoiding excessive straightening caused by excessive pressure of the straightening roller 5 on the wing plate. Optionally, the cleaning brush 82 is set in front of the station of the straightening roller 5, so that the wing plate will first pass through the cleaning brush 82 and then pass through the bottom of the straightening roller 5. This avoids the welding slag from entering the straightening range of the straightening roller 5 and being directly pressed into the steel surface by the eccentric extrusion of the straightening roller 5, which would affect the processing quality of the steel structure. It also avoids the welding slag from entering the detection area at the bottom of the detection roller 62, which would affect the detection accuracy.
