Description

Technical Field

[0001] This invention belongs to the field of metal machining technology, and in particular relates to a straightening device and method for processing steel plate components. Background Technology

[0002] The welded T-shaped steel column is composed of H-shaped steel plates and T-shaped steel plates, and then a straightening machine is used to straighten the welded T-shaped steel column. The processing sequence is as follows: first, the T-shaped steel plate is welded to the center line of the web of the H-shaped steel plate to form the T-shaped steel column; after welding, due to the effect of weld thermal shrinkage, the two sides of the center line of the web of the H-shaped steel plate will warp and deform towards the weld surface (i.e., the direction of the T-shaped steel plate), so the web needs to be straightened.

[0003] For example, utility model patent with publication number CN206153325U discloses a straightening device for irregular H-beams, which adopts a hook and claw structure to effectively straighten irregular H-beams, so as to ensure that the force of the jack can always act on the welding point or deformation area of ​​the irregular H-beam.

[0004] In existing technologies, welding requires the use of welding auxiliary equipment, and after welding, it needs to be transferred to a straightening machine for correction. The components need to be transferred, re-clamped, and aligned multiple times between different workstations, which is not only time-consuming and labor-intensive, but also accumulates positioning errors, resulting in process fragmentation and low efficiency.

[0005] When traditional straightening machines use jacks to press down on the web of H-beam steel plates for straightening, the enormous pressure is transmitted through the web to the T-beam steel plates below. Since the bottom of the T-beam steel plates is suspended, they are prone to secondary deformation (bending) or overall displacement, leading to straightening failure. Summary of the Invention

[0006] In view of the technical problems existing in the background art, the present invention provides a straightening device and method for processing steel plate components.

[0007] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0008] A straightening device for processing steel plate components, used for straightening T-shaped steel columns, wherein the T-shaped steel columns are composed of T-shaped steel plates and H-shaped steel plates welded together, and the straightening device includes:

[0009] frame;

[0010] A positioning and conveying assembly is mounted on the frame;

[0011] A correction assembly is mounted on the frame and positioned above the positioning and conveying assembly. The correction assembly includes a plurality of jacks arranged side by side in a straight line.

[0012] The positioning and conveying component includes:

[0013] The correction platform is U-shaped with the opening facing upwards;

[0014] Several positioning cams are spaced apart along the length of the straightening platform and rotatably mounted inside the straightening platform; limit rings are symmetrically arranged on both sides of the positioning cams for lateral limiting of the T-shaped steel plate; the positioning cams are directly opposite the jacks above them;

[0015] The correction device has a first working state and a second working state:

[0016] In the first working state, the straightening device is used to assist in the welding of the T-shaped steel plate and the H-shaped steel plate;

[0017] At this time, the H-shaped steel plate is supported on the upper surface of the straightening platform by the two sides of the web plate, the T-shaped steel plate is set on the upper surface of several positioning cams and abuts against the limiting ring on both sides, and the upper side of the T-shaped steel plate has a fixed distance from the web plate of the H-shaped steel plate.

[0018] By rotating the positioning cam, the T-shaped steel plate is driven to rise until its top is in contact with the center of the web of the H-shaped steel plate for welding.

[0019] In the second working state, the straightening device is used to straighten the T-shaped steel column that has deformed after welding;

[0020] At this time, the H-shaped steel plate is supported on the upper surface of the straightening platform by the two sides of the web plate, the two sides of the T-shaped steel plate abut against the limiting ring, and the positioning cam rotates to the release position, so that the bottom surface of the T-shaped steel plate disengages from the positioning cam and maintains a fixed distance.

[0021] The jack extends and applies downward corrective pressure to the center of the web of the H-shaped steel plate.

[0022] Optionally, the correction assembly further includes a top plate and an L-shaped clamp. An L-shaped mounting base is integrally provided on the top of the frame. Two mounting slots are symmetrically opened on the inner side of the mounting base. The L-shaped clamp is installed in the mounting slot by bolts. The top plate is engaged with the inner slots of the two L-shaped clamps. Several jacks are installed on the top plate.

[0023] Optionally, the positioning and conveying assembly further includes: a lifting unit that is vertically mounted on the outside of the correction platform, the lifting unit including several lifting frames configured in a U shape, rollers symmetrically arranged on both sides of the lifting frames, the rollers being located on the outside of the correction platform, and the two side wings of the H-shaped steel plate facing the rollers on the bottom side.

[0024] Optionally, several lifting frames are connected to the bottom side of the base plate, and several protruding posts are spaced apart on the base plate. Each protruding post corresponds to a positioning cam on the upper side, and the upper surface of the protruding post slides in close contact with the surface of the positioning cam. Several guide posts are evenly distributed at the bottom end of the base plate, and several fixed seats are provided on the frame. The fixed seats have guide holes inside, and the guide posts are slidably disposed in the guide holes. Springs are sleeved on the outside of the guide posts, and the upper and lower ends of the springs are in close contact with the base plate and the fixed seats, respectively.

[0025] Optionally, several guide sleeves are provided on both sides of the correction platform, and the lifting frame slides and rises close to the inner wall of the guide sleeve.

[0026] Optionally, several operating slots are provided on both sides of the correction platform.

[0027] Optionally, the bottom side of the correction platform is evenly distributed with several guide grooves, and the protrusion passes through the guide grooves upward and is connected to the positioning cam.

[0028] Optionally, the mounting base is threaded with a plurality of tightening screws, which extend downward and abut against the top plate.

[0029] A method for using a straightening device for processing steel plate components, comprising the following steps:

[0030] S1, the straightening device assists in welding the T-shaped steel plate and the H-shaped steel plate:

[0031] S11, Adjust the positioning cam to rotate to the release position, so that the lifting unit is in a high position and the upper end face of the roller is higher than the upper end face of the correction platform;

[0032] S12, the H-shaped steel plate is supported on the rollers by the two sides of the web, and the H-shaped steel plate does not contact the upper end face of the straightening platform; the T-shaped steel plate is set on the upper surface of a plurality of positioning cams and abuts against the limiting ring on both sides, so that the upper side of the T-shaped steel plate and the web of the H-shaped steel plate have a fixed distance.

[0033] S13, control the jack to extend and press the H-shaped steel plate down to fit tightly against the upper surface of the straightening platform;

[0034] S14, by rotating the positioning cam, the T-shaped steel plate is driven to rise until its top is in contact with the center of the web of the H-shaped steel plate and welded together, thus welding the T-shaped steel plate and the H-shaped steel plate together to form a T-shaped steel column;

[0035] S2, The T-shaped steel column that has deformed after welding is corrected using the corrective device:

[0036] S21, after welding is completed, the jack retracts to its original position, so that the lifting unit is reset to the high position, so that the rollers rise and lift the T-shaped steel column as a whole, so that the H-shaped steel plate is removed from the upper surface of the straightening platform.

[0037] S22, Adjust the positioning cam to rotate to the release position so that the bottom side of the T-shaped steel plate and the upper surface of the positioning cam have a fixed distance;

[0038] S23, by rotating the positioning cam, the convex column is driven to descend, so that the lifting unit is lowered to the low position, and the rollers are lowered to the bottom side of the wing plates on both sides of the H-shaped steel plate; during the descent, the rollers lower the T-shaped steel column as a whole, and the H-shaped steel plate is supported on the upper surface of the straightening platform again.

[0039] S24, control the jack to extend and apply downward corrective pressure to the center of the web of the H-beam steel plate.

[0040] The present invention has the following advantages and beneficial effects:

[0041] 1. Process integration significantly improves processing efficiency.

[0042] This invention integrates three processes—assembling and lifting T-shaped steel plates, welding them with H-shaped steel plates, and straightening the web plates after welding—into a single workstation by setting up a positioning and conveying component on the same equipment. The rotation of a positioning cam switches between a first working state (welding) and a second working state (straightening). From the moment the component enters the equipment until straightening is complete, there is no need for intermediate hoisting or secondary clamping, eliminating the waiting time and repetitive positioning time caused by inter-process transfers in traditional processes.

[0043] 2. Protective straightening to prevent secondary deformation of the T-shaped steel plate.

[0044] This invention positions and installs the T-shaped steel plate during welding, ensuring it remains in the straightening position immediately after welding. In the straightening state (second working state), a unique "lateral limiting + bottom release" constraint method is employed. Firstly, the limiting rings on both sides of the positioning cam laterally limit the T-shaped steel plate, effectively resisting lateral bending that may occur during the straightening pressure transmission process. Secondly, when the positioning cam rotates to the release position, the bottom surface of the T-shaped steel plate disengages from the cam, maintaining a gap and preventing the straightening force from acting directly on the bottom of the T-shaped steel plate through the web. This design ensures that the straightening force is precisely applied to the deformation area of ​​the web of the H-shaped steel plate, while providing all-around protection for the welded T-shaped steel plate throughout the straightening process, eliminating the process defect of "straightening one plate while bending another."

[0045] 3. Precise assembly to control welding deformation from the source.

[0046] In the welding state (first working state), this invention utilizes the rotation of a positioning cam to smoothly and precisely lift the T-shaped steel plate to its center position against the web of the H-shaped steel plate. Compared to the traditional assembly method relying on manual marking and pry bar adjustments, the cam lifting mechanism of this invention provides stepless adjustment for precise alignment, ensuring the uniformity and consistency of the gap between the T-shaped steel plate and the web. Precise assembly not only improves the quality of the welded joint but also reduces additional welding stress caused by misalignment or excessive gaps, significantly reducing post-weld deformation and simplifying subsequent straightening processes.

[0047] In summary, this invention, through its ingenious integrated structural design, effectively solves the technical problems of cumbersome processing procedures and unstable straightening quality in existing technologies for welded T-shaped steel columns. Attached Figure Description

Detailed Implementation

[0073] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 some embodiments of the present invention, but not all embodiments.

[0074] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0075] Example 1

[0076] like Figures 1-3 As shown, a straightening device for processing steel plate components is used to straighten welded T-shaped steel columns, which are composed of T-shaped steel plates 71 and H-shaped steel plates 7 welded together.

[0077] like Figures 1-3 As shown, the straightening device includes: a frame 1, a positioning and conveying assembly, and a straightening assembly. The positioning and conveying assembly is mounted on the frame 1, and one side of the frame 1 is supported by a triangular side bracket 2 to improve its anti-overturning capability. The straightening assembly is mounted on the frame 1 and located above the positioning and conveying assembly.

[0078] like Figures 1-3 As shown, the straightening assembly includes several jacks 34 arranged side by side on the same straight line. A pressure block 35 is installed on the telescopic shaft of the jack 34. The bottom end of the pressure block 35 has a long strip-shaped pressure strip. The straightening is achieved by directly contacting the web of the H-beam steel plate 7 with the pressure strip.

[0079] like Figures 1-4 ,like Figures 16-18As shown, preferably, the straightening assembly also includes a top plate 33 and L-shaped clamps 32. An L-shaped mounting base 3 is integrally provided on the top of the frame 1, and the frame 1 and mounting base 3 form a U-shaped structure. Two mounting slots 31 are symmetrically provided on the inner side of the mounting base 3. L-shaped clamps 32 are bolted into the mounting slots 31. A connecting plate 321 is integrally connected to the top of the L-shaped clamps 32. The connecting plate 321 has connecting holes and is installed in the mounting slots 31, achieving a detachable connection with the mounting base 3 through the connecting holes. The two L-shaped clamps 32 are arranged along the length of the frame 1 and are symmetrically positioned. The bottom side of the L-shaped clamps 32 has an inner groove, and the top plate 33 is fitted into the inner groove of the two L-shaped clamps 32. Several jacks 34 are installed on the top plate 33. This structure ensures that the jacks 34 are securely and reliably installed and facilitates disassembly and maintenance.

[0080] like Figures 1-4 ,like Figures 16-18 As shown, further, the mounting base 3 is threaded with several tightening screws 36. The tightening screws 36 are located in the middle of the two mounting slots 31. The tightening screws 36 extend downward and abut against the top plate 33. The top plate 33 can be fixed by adjusting the tightening screws 36, which facilitates the disassembly and assembly of the top plate 33. The top plate 33 and the jack 34 on the top plate 33 can be disassembled as a whole.

[0081] like Figures 1 to 24 As shown, the positioning and conveying assembly includes: a correction platform 4 and several positioning cams 5.

[0082] The correction platform 4 is set in a U shape with the opening facing upwards.

[0083] Several positioning cams 5 are spaced apart along the length of the straightening platform 4 and are rotatably mounted inside the straightening platform 4. Limiting rings 51 are symmetrically arranged on both sides of the positioning cams 5 to laterally limit the movement of the T-shaped steel plate 71. The positioning cams 5 are directly opposite the jacks 34 above them. Specifically, the positioning cams 5 are fixedly sleeved on the outside of a central shaft 52, with bearings 53 at both ends of the central shaft 52. The bearings 53 are installed in the inner hole of the straightening platform 4, enabling the rotational mounting of the positioning cams 5.

[0084] like Figure 24 As shown, preferably, the positioning cam 5 can be driven by gears, racks / belts. Two gears 54 are installed on one side of the central shaft 52, and the gears 54 of two adjacent positioning cams 5 are connected and transmitted in sequence through racks / belts. Finally, a motor with a reducer is arranged on the outside of one of the central shafts 52 to drive the cams, thereby synchronously driving several positioning cams 5 to rotate synchronously.

[0085] Preferably, the positioning and conveying assembly also includes a lifting unit that is vertically mounted on the outside of the correction platform 4.

[0086] like Figures 16-24 As shown, the lifting unit includes several lifting frames 64 configured in a U shape. Each pair of lifting frames 64 is connected to the two sides by a connecting rod 67 to form a group. Rollers 65 are symmetrically arranged on both sides of the lifting frame 64. The rollers 65 are provided with annular flanges 66 on their sides. The rollers 65 are located on the outside of the straightening platform 4. The two side wings of the H-shaped steel plate 7 are directly opposite the rollers 65 on the bottom side.

[0087] like Figures 1 to 24 As shown, furthermore, several lifting frames 64 are connected to the bottom of the base plate 6, which is located on the bottom of the correction platform 4. The base plate 6 moves up and down close to the inner wall of the fixing seat 11. Several protruding posts 61 are spaced apart on the base plate 6. The upper end of the protruding post 61 is set as an arc-shaped outer circular surface. The protruding post 61 is correspondingly set with the positioning cam 5 on the upper side. The upper surface of the protruding post 61 is in close sliding contact with the surface of the positioning cam 5. Several guide posts 62 are evenly distributed at the bottom end of the base plate 6. Several fixing seats 11 are set on the frame 1. The fixing seat 11 has a guide hole 12 inside. The guide post 62 is slidably set in the guide hole 12. A spring 63 is sleeved on the outside of the guide post 62. The upper and lower ends of the spring 63 are in close contact with the base plate 6 and the fixing seat 11, respectively.

[0088] like Figure 4 and Figure 21 As shown, preferably, the correction platform 4 is provided with several guide sleeves 68 on both sides, and the lifting frame 64 slides and rises and falls close to the inner wall of the guide sleeve 68 to ensure that the lifting frame 64 rises and falls smoothly.

[0089] like Figure 16 and Figure 17 As shown, preferably, the straightening platform 4 has several operating slots 42 on both sides, which facilitates the operator to perform welding operations through the operating slots 42, and at the same time, the internal welding and straightening situation can be observed.

[0090] like Figure 6 and Figure 17 As shown, preferably, the bottom side of the correction platform 4 is evenly distributed with several guide grooves 41, and the protrusion 61 passes through the guide groove 41 upward and is connected to the positioning cam 5, so that the movement trajectory of the protrusion 61 is constrained, ensuring precise cooperation with the positioning cam 5.

[0091] In this invention, the correction device has a first working state and a second working state:

[0092] In the first working state (welding stage), the straightening device is used to assist in the welding of the T-shaped steel plate 71 and the H-shaped steel plate 7.

[0093] At this time, the H-shaped steel plate 7 is supported on the upper surface of the straightening platform 4 by the two sides of its web, and the T-shaped steel plate 71 is set on the upper surface of several positioning cams 5 and abuts against the limiting rings 51 on both sides to achieve lateral positioning. The upper side of the T-shaped steel plate 71 and the web of the H-shaped steel plate 7 have a fixed interval, providing a safe installation gap to ensure that the T-shaped steel plate 71 and the H-shaped steel plate 7 do not contact each other or affect each other during positioning and installation.

[0094] The positioning cam 5 is rotated by an external drive mechanism (such as a motor), driving the T-shaped steel plate 71 to rise until its top is in contact with the center of the web of the H-shaped steel plate 7 for welding. Welding is then performed to weld the T-shaped steel plate 71 and the H-shaped steel plate 7 together, forming a T-shaped steel column.

[0095] In the second working state (correction stage), the correction equipment is used to correct the T-shaped steel columns that have deformed after welding.

[0096] After welding, the H-shaped steel plate 7 is supported on the upper surface of the straightening platform 4 by the two sides of the web. The two sides of the T-shaped steel plate 71 abut against the limiting rings 51, ensuring that the T-shaped steel plate 71 is positioned in the same position before and after welding. An external drive mechanism (such as a motor) rotates the positioning cam 5 to the release position. At this time, the contour of the positioning cam 5 changes from a high point to a low point, causing the bottom surface of the T-shaped steel plate 71 to disengage from the positioning cam 5 and maintain a fixed distance. The T-shaped steel plate 71 is only laterally constrained by the limiting rings 51 on both sides, and its bottom is suspended. This fixed distance ensures that the entire T-shaped steel column has downward displacement space during straightening, avoiding collision and interference between the T-shaped steel plate 71 and the positioning cam 5 during the straightening process.

[0097] Then, the jack 34 is extended to apply downward corrective pressure to the center of the web of the H-beam 7. Since the web of the H-beam 7 is suspended (the T-beam 71 has been disengaged from the positioning cam 5) and the T-beam 71 is laterally constrained by the limiting ring 51, the corrective force can be applied precisely to the deformed area of ​​the web to flatten it, while the T-beam 71 will not undergo secondary torsional deformation.

[0098] Example 2

[0099] This embodiment provides a correction method using the correction device described in Embodiment 1, including the following steps:

[0100] S1, the straightening device assists in welding the T-shaped steel plate 71 and the H-shaped steel plate 7:

[0101] S11, such as Figure 4-6As shown, the positioning cam 5 is adjusted to rotate to the release position. At this time, the circular contour of the positioning cam 5 cooperates with the protrusion 61, and the elliptical contour of the positioning cam 5 faces the horizontal direction. After the lifting unit loses the limit of the positioning cam 5, it is reset to the highest point by the spring 63, so that the lifting unit is in a high position and the upper end surface of the roller 65 is higher than the upper end surface of the correction platform 4.

[0102] S12, as Figure 4-6 , Figure 21 As shown, the H-beam steel plate 7 is supported on rollers 65 by flanges on both sides of its web. The flanges are in close contact with the side guards 66 for positioning, and the H-beam steel plate 7 does not contact the upper surface of the straightening platform 4. This allows the H-beam steel plate 7 to be smoothly installed in place via the rollers 65, avoiding scratches between the H-beam steel plate 7 and the straightening platform 4 that could cause damage during the positioning process. Then, the T-beam steel plate 71 is placed on the upper surface of several positioning cams 5, with its sides abutting against the limiting rings 51, thus positioning the T-beam steel plate 71 and creating a fixed gap between the upper side of the T-beam steel plate 71 and the web of the H-beam steel plate 7. This gap facilitates separate positioning and installation.

[0103] S13, as Figure 7-9 As shown, the jack 34 extends to press the H-shaped steel plate 7 down and press it tightly against the upper surface of the straightening platform 4. This serves two purposes: first, to ensure the H-shaped steel plate 7 is reliably and accurately positioned on the straightening platform 4; and second, to bring it close to the bottom T-shaped steel plate 71, preparing for subsequent welding. During the downward pressing of the jack 34, the H-shaped steel plate 7 descends in conjunction with the roller 65, ultimately causing the entire lifting unit to descend, and the protruding column 61 to descend away from the positioning cam 5.

[0104] S14, as Figure 7-9 As shown, by rotating the positioning cam 5, the elliptical contour of the positioning cam 5 gradually contacts the bottom end of the T-shaped steel plate 71, driving the T-shaped steel plate 71 to rise until its top is in contact with the center of the web of the H-shaped steel plate 7 and welded together, thus welding the T-shaped steel plate 71 and the H-shaped steel plate 7 together to form a T-shaped steel column. After positioning and installing the T-shaped steel plate 71 and the H-shaped steel plate 7, the H-shaped steel plate 7 is then stably supported on the straightening platform 4. The positioning cam 5 is used to precisely lift the T-shaped steel plate 71, so that the center of the web of the T-shaped steel plate 71 and the H-shaped steel plate 7 are in contact, achieving a precise welding operation.

[0105] like Figure 9 As shown, after the top of the T-shaped steel plate 71 contacts the web of the H-shaped steel plate 7, the positioning cam 5 has not yet rotated to the highest position. This restriction is for the purpose of fine-tuning the lateral position of the T-shaped steel column during the subsequent correction process. By fully rotating the positioning cam 5, the T-shaped steel column is lifted and moved laterally by a fixed distance, thereby achieving top pressure correction at different positions.

[0106] S2, The T-shaped steel column that has deformed after welding is corrected using the corrective device:

[0107] S21, as Figure 10-12 As shown, after welding is completed, the jack 34 retracts to its original position. After the lifting unit removes the pressure from the jack 34, the lifting unit is reset to a high position by the spring 63, and the roller 65 rises to lift the welded T-shaped steel column as a whole, so that the H-shaped steel plate 7 is removed from the upper end face of the straightening platform 4, and at the same time, the bottom side of the T-shaped steel plate 71 is also removed from the positioning cam 5.

[0108] S22, adjust the positioning cam 5 to the release position, so that the positioning cam 5 is away from the T-shaped steel plate 71, so that the bottom side of the T-shaped steel plate 71 and the upper surface of the positioning cam 5 have a fixed distance, providing a larger correction space. In steps S21 and S22, the T-shaped steel plate 71 is always laterally constrained by the limiting rings 51 on both sides, ensuring that it is always positioned in the same position before and after welding.

[0109] S23, as Figure 13-15 As shown, by rotating the positioning cam 5, the elliptical contour of the positioning cam 5 gradually contacts the top of the protruding column 61, driving the protruding column 61 to descend, causing the lifting unit to descend to its lowest position, and causing the roller 65 to descend to the bottom side of the flanges on both sides of the H-shaped steel plate 7. This ensures that the roller 65 and the flanges on both sides of the H-shaped steel plate 7 do not contact each other, providing a prerequisite for correction and preventing the H-shaped steel plate 7 from being subjected to force on the roller 65 during the correction process. During the descent, the roller 65 lowers the T-shaped steel column as a whole, and the H-shaped steel plate 7 is once again supported on the upper surface of the correction platform 4, allowing the correction operation to be performed.

[0110] This design allows for height adjustment using the lifting unit (roller 65) throughout the process, providing a basis for welding and straightening. The lifting unit (roller 65) can be used to install the single component H-shaped steel plate 7 before welding, and the lifting unit (roller 65) can be used to move the welded integral component T-shaped steel column (H-shaped steel plate 7 and T-shaped steel plate 71) out as a whole.

[0111] S24, control the extension of the jack 34 to apply downward straightening pressure to the center of the web of the H-beam steel plate 7 until the flatness of the web meets the specification requirements. During the straightening process, if fine adjustment of the straightening position is required, the positioning cam 5 can be controlled to rotate, continuously raising the position of the transverse T-beam steel column, thereby realizing the straightening operation at different positions.

[0112] S25. After the correction is completed, the positioning cam 5 rotates to the release position and does not contact the bottom end of the T-shaped steel plate 71. The jack 34 retracts and resets. The lifting unit lifts the T-shaped steel column as a whole, so that the corrected T-shaped steel column is away from the correction platform 4. Then the T-shaped steel column is pulled outward as a whole. Through the sliding support of the roller 65, the T-shaped steel column is smoothly removed.

[0113] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
