[0040] To make the objectives, technical solutions and advantages of this application clearer, the following will clearly and completely describe the technical solutions in this application and how the technical solutions in this application solve the above technical problems by using specific embodiments in combination with the accompanying drawings in this application. Obviously, the described embodiments are some but not all of the embodiments of this application. These several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

[0041] The terms "first", "second", "third", "fourth", etc. (if any) in the specification, claims and above-mentioned accompanying drawings of this application are used to distinguish similar objects and do not have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of this application described here can be implemented in an order different from those illustrated or described here, for example.

[0042] In the embodiments of this application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in this application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, using words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0043] Metal rolling is a manufacturing process that processes metal billets into the required thickness and shape through mechanical force. The large mechanical force during the rolling process makes it easy for adhesion to occur between the rolling rolls and the metal billet, resulting in bending of the rolled metal workpiece at the adhesion points. When there are multiple adhesions between the rolling rolls and the metal billet, different positions of the same metal workpiece will exhibit different degrees of bending.

[0044] In the related art, a workbench is provided for placing a metal rolling piece to be straightened thereon, and a hydraulic plate is provided on the workbench. According to the thickness and bending degree of the metal rolling piece to be straightened, a suitable pressure is set for the hydraulic plate, and it is ensured that the bending part of the metal rolling piece to be straightened is located within the action area of the hydraulic plate. Pressure is applied to the bending part of the metal rolling piece to be straightened through the hydraulic plate to straighten the metal rolling piece.

[0045] However, the position of the hydraulic plate of the above device is fixed. For the bending at different positions of the same metal rolling piece to be straightened, the metal rolling piece needs to be moved successively to make the bending part correspond to the action area of the hydraulic plate, and then the hydraulic plate is started for straightening, resulting in low straightening efficiency.

[0046] The embodiment of the present application provides a straightening device for annealing treatment of metal plates. The straightening device includes a support assembly, at least one moving assembly, and at least one straightening mechanism. By providing the support assembly, four moving parts are slidably arranged on the support assembly, wherein two inner moving parts are used to jointly clamp the metal plate, and at least two first straightening assemblies are respectively slidably connected to the two outer moving parts; at least two second straightening assemblies are slidably connected to the first straightening assemblies, and straightening parts are rotatably arranged on the second straightening assemblies. In this way, by clamping the metal plate on the two inner moving parts inside the straightening device, the two outer moving parts are moved towards the two inner moving parts, so that each straightening part moves towards the metal plate, and the first straightening assemblies and the second straightening assemblies are slid, so that each straightening part correspondingly moves to different parts to be straightened of the metal plate, so that the straightening parts on the two moving parts can be relatively clamped on both sides of the part to be straightened of the metal plate. Thus, the parts to be straightened at different positions on the metal plate can be clamped by a plurality of oppositely arranged straightening parts, and straightening can be simultaneously achieved under the high-temperature softening action of the annealing treatment to improve the straightening efficiency.

[0047] The technical solution of the present application will be described in detail below with specific embodiments in conjunction with the accompanying drawings. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0048] As Figure 1 、 Figure 2 、 Figure 3 and Figure 8 shown, the embodiment of the present application provides a straightening device for annealing treatment of metal plates. The straightening device includes a support assembly 100, at least one moving assembly 200, and at least one straightening mechanism 300; the moving assembly 200 includes four moving parts 210 slidably arranged on the support assembly 100 in sequence, and the two inner moving parts 210 are used to jointly clamp the metal plate.

[0049] The straightening mechanism 300 includes a plurality of first straightening components 310 and at least two second straightening components 320 slidably arranged on each of the first straightening components 310, and at least one straightening member 330 is rotatably arranged on the second straightening components 320. At least two first straightening components 310 are slidably connected to both of the two moving members 210 located outside.

[0050] The straightening members 330 on the two moving members 210 are configured such that when the two moving members 210 located outside move towards the two moving members 210 located inside, driven by the second straightening components 320, they move towards the metal sheet, and when moving to a preset position, they rotate relative to the second straightening components 320 to respectively clamp on opposite sides of the portion of the metal sheet to be straightened.

[0051] It should be noted that when a metal material is rolled into a metal sheet, during the rolling process, the metal material will be subjected to great mechanical stress, and these stresses will generate internal stresses inside the metal, resulting in deformation, cracking or other adverse phenomena of the metal during subsequent processing or use. Annealing treatment is to heat the metal to a specific temperature. The metal sheet is in a softened state at the high temperature of the annealing treatment, so that the grain structure inside the metal changes, thereby eliminating the internal stress and making the metal sheet more stable.

[0052] In the implementation of this application, exemplarily, the four moving members 210 are sequentially and spacedly inserted on the support assembly 100. Among them, the metal sheet is placed between the two moving members 210 located in the middle, and the two moving members 210 located in the middle are close to each other to jointly clamp the metal sheet.

[0053] In specific settings, at least two first straightening components 310 are respectively slidably connected to the two moving members 210 located outside, and the two first straightening components 310 are both parallelly distributed at opposite ends of the moving member 210, so that each first straightening component 310 can slide simultaneously along the first direction relative to the moving member 210 where it is located; at least two second straightening components 320 are slidably arranged on each first straightening component 310, and the two second straightening components 320 are arranged in parallel, so that each second straightening component 320 can slide simultaneously along the second direction relative to the first straightening component 310 where it is located; at least one straightening member 330 is rotatably arranged on the second straightening component 320, and the rotation axes of the straightening members 330 are all parallel to each other, so that the straightening member 330 rotates around the third direction where the rotation axis is located; in addition, each moving member 210 also slides along the third direction relative to the support assembly 100.

[0054] It should be noted that in the embodiment of this application, the first direction refers to Figure 1 the X direction shown in Figure 1 and the second direction refers to Figure 1As shown in the Z direction, it can be understood that the first direction, the second direction, and the third direction are perpendicular to each other.

[0055] In specific implementation, as Figure 2 and Figure 3 shown, by clamping the metal sheet on two moving members 210 located inside the straightening device, moving the two moving members 210 located outside towards the two moving members 210 located inside, so that the straightening members 330 on the two moving members 210 all move towards the metal sheet; by sliding the first straightening assembly 310 and the second straightening assembly 320 along the perpendicular first direction and second direction respectively, so that each straightening member 330 correspondingly moves to a preset position. It can be understood that the preset position is different parts of the metal sheet to be straightened, and the straightening members 330 on the two moving members 210 on the opposite sides of the same part to be straightened are located on the same straight line. By rotating the straightening members 330, the two straightening members 330 can relatively clamp the two sides of the part of the metal sheet to be straightened.

[0056] In actual use, a plurality of oppositely arranged straightening members 330 are clamped on the parts of the metal sheet to be straightened at different positions. Exemplarily, the two moving members 210 located outside can be fixed by buckles or threaded fasteners, so that the positions of the four moving members 210 relative to the support assembly 100 are fixed to ensure that the straightening members 330 are in close contact with the parts of the metal sheet to be straightened. Subsequently, the device and the metal sheet are placed in an annealing device as a whole, and softened by the high temperature of the annealing treatment, so that the parts of the metal sheet to be straightened are straightened under the clamping action of the two opposite straightening members 330, and the parts to be straightened at multiple positions can be straightened simultaneously, thereby improving the straightening efficiency.

[0057] It should be noted that the surface of the straightening member 330 for clamping the part of the metal sheet to be straightened in the embodiment of the present application should ensure good flatness, so that the straightening member 330 has a better straightening effect on the part to be straightened in a high-temperature environment.

[0058] It can be understood that the set numbers of the first straightening assembly 310 and the second straightening assembly 320 are only given exemplarily, and are specifically set according to the size adaptability of the actually to-be-straightened metal sheet, ensuring that the metal sheet can be clamped by the moving assembly 200, and the number of the straightening members 330 can cover the number of the parts to be straightened on the metal sheet. In addition, in the embodiment of the present application, the four moving members 210 are a set of moving assemblies 200, and the set number of the moving assemblies 200 can be determined according to the number of the to-be-straightened metal sheets, and a plurality of moving assemblies 200 can be sequentially and spacedly arranged on the support assembly 100 to meet the simultaneous straightening of multiple metal sheets.

[0059] In some embodiments, the first straightening assembly 310 includes a first slider 311 and at least one first fixing member 312 rotatably disposed on the first slider 311. The first slider 311 is slidably connected to the moving member 210, and the second straightening assembly 320 is slidably connected to the first slider 311.

[0060] The first fixing member 312 is configured to rotate relative to the first slider 311 until it is connected to the moving member 210 to fix the first slider 311.

[0061] In the embodiments of the present application, as Figure 1 , Figure 2 , Figure 4 and Figure 8 shown, the first slider 311 is used for slidably connecting to the moving member 210, and the second straightening assembly 320 is slidably connected to the first slider 311. Exemplarily, first sliders are provided on both opposite sides of the first slider 311, and first sliding grooves are correspondingly provided on the moving member 210. The opening direction of the first sliding groove refers to the X direction shown in Figure 1 . In this way, the first sliders are inserted into the first sliding grooves to drive the second straightening assembly 320 to slide relative to the moving member 210 along the first direction (refer to the X direction shown in Figure 2 ).

[0062] In specific implementation, a first fixing member 312 is provided on the first slider 311. Exemplarily, the first fixing member 312 is a fastener such as a pin shaft or a screw, and the axis of the rotation shaft of the first fixing member 312 is perpendicular to the first sliding groove. In this way, when the first slider 311 slides relative to the moving member 210 to a preset position, by rotating the first fixing member 312, one end of the first fixing member 312 is inserted into the first sliding groove. At this time, through the interference fit between the first fixing member 312 and the first sliding groove, the first slider 311 is reliably fixed on the moving member 210.

[0063] By providing the first slider 311, the assembly of the second straightening assembly 320 on the moving member 210 is easy to achieve, and by providing the first fixing member 312, it is possible to avoid the clamping position of the straightening member 330 from deviating due to the shaking of the first slider 311 during the straightening process.

[0064] It should be noted that the connection manner between the first slider 311 and the moving member 210 and the specific structure of the first fixing member 312 are only exemplarily given in the embodiments of the present application, and can be specifically set according to actual usage requirements. The present application does not impose too many restrictions on this.

[0065] In some embodiments, the first slider 311 includes a first connecting portion 3111 and first sliding portions 3112 disposed at two ends of the first connecting portion 3111. The moving member 210 has two opposite supporting portions 211. The two first sliding portions 3112 are respectively slidably connected to the two supporting portions 211, and the second straightening assembly 320 is slidably connected to the first connecting portion 3111.

[0066] At least one first fixing hole 3113 is provided on the first sliding portion 3112. The first fixing member 312 is rotatably connected in the first fixing hole 3113 to abut or disengage from the supporting portion 211.

[0067] In the embodiments of the present application, as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8 shown, the moving member 210 has two opposite supporting portions 211, and the first slider 311 has a first connecting portion 3111. Exemplarily, first sliding portions 3112 are provided at both ends of the first connecting portion 3111 by an integral molding or welding connection method. The first sliding portion 3112 has an L-shaped structure.

[0068] When specifically arranged, one side of the first sliding portion 3112 is connected to one end of the first connecting portion 3111, and the other side faces the other of the first sliding portions 3112. In this way, the two first sliding portions 3112 and the first connecting portion 3111 together enclose two opposite U-shaped sliding cavities, so that it is convenient for the first slider 311 to be slidably connected to the two supporting portions 211 through the two sliding cavities respectively, so as to slide relative to the moving member 210.

[0069] In addition, at least one first fixing hole 3113 is provided on at least one side of the L-shaped first sliding portion 3112 by punching or the like. In the embodiments of the present application, one first fixing hole 3113 is provided on each first sliding portion 3112, and the first fixing member 312 is correspondingly arranged with the first fixing hole 3113. Exemplarily, when the first fixing member 312 is a fastener such as a bolt, the first fixing hole 3113 is a threaded hole matching the bolt, so that the first fixing member 312 rotates through the first fixing hole 3113 until it abuts against the supporting portion 211; in this way, through the frictional force between the first fixing member 312 and the supporting portion 211, the sliding of the first sliding portion 3112 relative to the supporting portion 211 is restricted, so as to fix the position of the first slider 311 on the supporting portion 211.

[0070] It should be noted that when it is necessary to adjust the relative position of the first slider 311 on the moving member 210, the first fixing member 312 is rotated in the reverse direction so that the first fixing member 312 disengages from abutting against the supporting portion 211.

[0071] In some embodiments, the second straightening component 320 includes a second slider 321 and at least one second fixing member 322 rotatably disposed on the second slider 321. The second slider 321 is slidably connected to the first connecting portion 3111, and the straightening member 330 is rotatably connected to the second slider 321.

[0072] The second fixing member 322 is configured to rotate relative to the second slider 321 until it is connected to the first connecting portion 3111 to fix the second slider 321.

[0073] In the embodiments of the present application, as Figure 1 、 Figure 3 、 Figure 4 and Figure 6 shown, the second slider 321 is slidably connected to the first connecting portion 3111, and the straightening member 330 is rotatably connected to the second slider 321. Exemplarily, second sliders are provided on both opposite sides of the second slider 321, and second sliding grooves are correspondingly provided on the first connecting portion 3111. The opening direction of the second sliding groove refers to the Y direction shown in Figure 1 . In this way, the second slider is inserted into the second sliding groove to drive the straightening member 330 to slide relative to the first connecting portion 3111 along the second direction (refer to the Y direction shown in Figure 3 ).

[0074] In specific implementation, a second fixing member 322 is provided on the second slider 321. Exemplarily, the second fixing member 322 is a fastener such as a pin shaft or a screw, and the axis of the rotation shaft of the second fixing member 322 is perpendicular to the second sliding groove. In this way, when the second slider 321 slides relative to the first connecting portion 3111 to a preset position, by rotating the second fixing member 322, one end of the second fixing member 322 is inserted into the second sliding groove. At this time, through the interference fit between the second fixing member 322 and the second sliding groove, the second slider 321 is reliably fixed on the first connecting portion 3111.

[0075] By providing the second slider 321, the assembly of the straightening member 330 on the moving member 210 is easy to achieve, and by providing the second fixing member 322, it is possible to avoid the deviation of the clamping position of the straightening member 330 caused by the shaking of the second slider 321 during the straightening process.

[0076] It should be noted that the connection manner between the second slider 321 and the first connecting portion 3111 and the specific structure of the second fixing member 322 are only exemplarily given in the embodiments of the present application, and can be specifically set according to actual usage requirements. The present application does not impose too many restrictions on this.

[0077] In some embodiments, the second sliding member 321 includes a second connecting portion 3211 and second sliding portions 3212 provided at two ends of the second connecting portion 3211. Both of the second sliding portions 3212 are slidably connected to the first connecting portion 3111, and the straightening member 330 is rotatably connected to the second connecting portion 3211.

[0078] At least one second fixing hole 3213 is provided on the second sliding portion 3212. The second fixing member 322 is rotatably connected in the second fixing hole 3213 to abut against or disengage from the first connecting portion 3111.

[0079] In the embodiments of the present application, as Figure 1 , Figure 2 , Figure 4 and Figure 6 shown, second sliding portions 3212 are provided at both ends of the second connecting portion 3211 by an integrally formed or welded connection method. The second sliding portions 3212 also have an L-shaped structure.

[0080] When specifically arranged, the second sliding portions 3212 and the second connecting portion 3211 also jointly enclose two opposite U-shaped sliding cavities, so as to facilitate the second sliding member 321 to be slidably connected to the first connecting portion 3111 through the two sliding cavities respectively and slide relative to the first connecting portion 3111.

[0081] In addition, the second fixing holes 3213 are provided on at least one side of the L-shaped second sliding portion 3212 by punching or the like. In the embodiments of the present application, one second fixing hole 3213 is provided on each of the second sliding portions 3212. The second fixing member 322 is correspondingly arranged with the second fixing hole 3213. Exemplarily, when the second fixing member 322 is a fastener such as a bolt, the second fixing hole 3213 is a threaded hole matching the bolt, so that the second fixing member 322 rotates through the second fixing hole 3213 until it abuts against the first connecting portion 3111; in this way, the second fixing member 322 restricts the second sliding portion 3212 from sliding relative to the first connecting portion 3111 through the frictional force between the second fixing member 322 and the first connecting portion 3111, thereby fixing the position of the second sliding member 321 on the first connecting portion 3111.

[0082] It should be noted that when it is necessary to adjust the relative position of the second sliding member 321 on the first connecting portion 3111, the second fixing member 322 can be reversely rotated to disengage the second fixing member 322 from abutting against the first connecting portion 3111.

[0083] In the embodiments of the present application, as Figure 1As shown, exemplarily, each first connection portion 3111 on the two outer moving parts 210 is adjacent to the inner moving part 210, and the second connection portion 3211 is located between the first connection portion 3111 and the moving part 210 adjacent to the first connection portion 3111, so that the straightening part 330 can be clamped on both sides of the part to be straightened of the metal sheet after moving a short distance.

[0084] In some embodiments, the straightening member 330 includes a plug-in portion 331 and a straightening portion 332 arranged in sequence, a rotation hole 3214 is provided on the second connecting portion 3211, the plug-in portion 331 is rotatably connected to the second connecting portion 3211 through the rotation hole 3214, and the straightening portion 332 faces one side of the moving member 210 located inside.

[0085] In the embodiments of the present application, Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, illustratively, the plug-in portion 331 and the straightening portion 332 are processed into one piece by means of one-piece molding, and an external thread is provided on the outer wall of the plug-in portion 331; the rotating hole 3214 is processed on the second connecting portion 3211 by means of punching, and an internal thread matching the external thread is provided on the inner wall of the rotating hole 3214, so that the plug-in portion 331 is connected to the rotating hole 3214 by means of threaded connection. In addition, the straightening portion 332 has a circular structure and faces one side of the moving part 210 located inside. The straightening portion 332 can also be a rectangular structure, etc., as long as the side of the straightening portion 332 that contacts the metal plate to be straightened has good flatness, and the embodiment of the present application does not limit this.

[0086] In specific implementation, by rotating the plug-in part 331, the straightening part 332 is driven by the plug-in part 331 to move toward one side of the inner moving part 210, so that the straightening parts 330 on the two outer moving parts 210 are relatively clamped on the part of the metal plate to be straightened.

[0087] It is understandable that when it is necessary to release the clamping of the straightening portion 332 on the portion of the metal plate to be straightened, it can be done by rotating the plug-in portion 331 in the reverse direction.

[0088] In some embodiments, the straightening member 330 also includes a stop portion 333, which is arranged at one end of the plug-in portion 331 away from the straightening portion 332, and a slot 3114 is provided on the first connecting portion 3111. The stop portion 333 is inserted into the slot 3114 and slides relative to the first connecting portion 3111 along the slot 3114 under the drive of the second connecting portion 3211.

[0089] In the embodiments of the present application, Figure 1 , Figure 4 ,Figure 6 and Figure 7 As shown in Figure 7 , a stop portion 333 is provided at one end of the insertion portion 331 of the straightening member 330 that faces away from the straightening portion 332, that is, the straightening portion 332 and the stop portion 333 are respectively located at both ends of the insertion portion 331; Exemplarily, the stop portion 333 is connected to the end of the insertion portion 331 by means of integral molding or interference fit, etc. Correspondingly, a slot 3114 is provided on the first connecting portion by means of integral molding, and the opening direction of the slot 3114 is consistent with the sliding trajectory of the second connecting portion 3211.

[0090] In specific implementation, the insertion portion 331 is inserted into the rotation hole 3214, and is driven by the second connecting portion 3211 to slide relative to the first connecting portion 3111 along the slot 3114. By providing the stop portion 333, it is convenient to apply torque to the stop portion 333, thereby driving the insertion portion 331 to rotate relative to the rotation hole 3214. At the same time, it can also prevent the insertion portion 331 from disengaging from the rotation hole 3214 when rotating relative to the rotation hole 3214, so as to improve the reliability of use. By providing the slot 3114, it provides an avoidance for the insertion portion 331 to slide relative to the first connecting portion 3111 to avoid interference.

[0091] In some embodiments, the moving member 210 further includes two mounting portions 212, and two opposite support portions 211 are sequentially connected through the mounting portions 212.

[0092] In the embodiment of the present application, as Figure 1 , Figure 2 , Figure 3 and Figure 8 shown, the moving member 210 includes two opposite support portions 211, and the support portions 211 are connected through the mounting portions 212. In this way, the two mounting portions 212 are also oppositely arranged, so that the support portions 211 and the mounting portions 212 sequentially surround to form a rectangular moving member 210.

[0093] By providing the mounting portions 212, the moving member 210 as a whole has good structural stability, and it is convenient for the moving member 210 to be assembled on the support assembly 100 through the mounting portions 212.

[0094] In some embodiments, the support assembly 100 includes at least two support members 110 arranged at intervals, and adjusting members 120 are respectively rotatably provided at both ends of the support members 110.

[0095] Each moving member 210 is sequentially slidably provided on the support member 110 and is located between the adjusting members 120; the adjusting member 120 is used to fix the two moving members 210 located outside.

[0096] Continuing as Figure 1 , Figure 2 , Figure 3 andFigure 8 As shown, the support assembly 100 includes a plurality of support members 110 arranged at intervals. In the embodiment of the present application, by way of example, the moving member 210 has a quadrilateral structure, and correspondingly, the number of support members 110 is set to four.

[0097] In specific implementation, the support member 110 can be a lead screw. Insertion holes are respectively provided at the four vertex angles of the moving member 210, and the moving member 210 is correspondingly inserted on each support member 110 through the insertion holes; when the four moving members 210 are inserted on the support members 110, adjusting members 120 are respectively arranged at both ends of the support members 110 so that the four moving members 210 are all located between the adjusting members 120. The adjusting member 120 can be a nut sleeve matching the lead screw.

[0098] In specific use, by adjusting the relative positions of the moving members 210 on the support members 110 along the third direction (as shown by the Z direction in the reference Figure 1 ), the metal sheet is clamped on the two inner moving members 210, and the two outer moving members 210 are moved towards the two inner moving members 210 so that the straightening members 330 on the two moving members 210 all move towards the metal sheet.

[0099] By arranging the adjusting member 120 on the support member 110, when a plurality of oppositely arranged straightening members 330 are clamped on the parts to be straightened at different positions of the metal sheet, by tightening the nut sleeve on the lead screw, the positions of the four moving members 210 on the support member 110 are fixed, thereby ensuring that the straightening members 330 are in close contact with the parts to be straightened of the metal sheet to ensure the straightening effect.

[0100] It should be noted that the specific structures of the support member 110 and the adjusting member 120 are only given by way of example, and the embodiments of the present application do not make specific limitations thereto, as long as it is ensured that the support member 110 and the adjusting member 120 can be matched and connected, and the adjusting member 120 has a fixing effect on the moving member 210 on the support member 110.

[0101] In the embodiment of the present application, at least one end of the support member 110 is provided with a support seat, and the support seats on each support member 110 are all located on the same side. By arranging the support seat, the contact area between the support member 110 and the annealing equipment is increased, which is convenient for the overall device to be stably placed under the support of the support seat.

[0103] In specific settings, a plurality of positioning members 130 are further provided on the support member 110. Exemplarily, the positioning member 130 is a buckle that matches the support member 110.

[0104] In specific implementation, when the metal sheet is clamped on two inner moving members 210, by clamping the buckle on one side of the two inner moving members 210 facing the outer moving member 210, the two inner moving members 210 are pre-fixed, so that the metal sheet is firmly clamped between the two inner moving members 210, preventing the metal sheet from shaking between the two moving members 210.

[0105] In the embodiments of the present application, the positioning member 130 can also be a structural member the same as the adjusting member 120, such as a nut sleeve that matches the support member 110, so that the positioning member 130 and the adjusting member 120 can be assembled without distinction, thereby facilitating the improvement of the assembly efficiency when the device is used; the specific structure of the positioning member 130 can be set adaptively according to actual use requirements, and the embodiments of the present application do not limit this.
