Description

TECHNICAL FIELD

[0001] The present application relates to the field of metal plate correction, in particular to a metal plate clamping and correcting device. BACKGROUND

[0002] In industrial production, various types of plates are often used. During production, transportation and use, some plates may be bent. The bent part of the plate is usually corrected by pressing, i.e. the bent part is directly flattened, so that the plate can continue to be used.

[0003] The existing structure usually uses a pressing roller or the like to operate. However, the surface of the pressing roller is flat, and the surface of the plate may have a certain groove. In this case, the plate may be bent when the pressing roller is operated, and the plate cannot be corrected. SUMMARY

[0004] The present application provides the following technical solutions to overcome the deficiencies of the prior art.

[0005] The metal plate clamping and correcting device comprises at least two groups of mounting racks arranged on the same horizontal plane and a middle shaft rotatably connected to the mounting racks.

[0006] Specifically, a plurality of extrusion rings are detachably arranged on the outer side of the middle shaft. The extrusion ring comprises a positioning plate and an adjusting plate. The positioning plate and the adjusting plate are connected end to end to form a ring structure. One end of the adjusting plate is inserted into the inside of the positioning plate to adjust the radius of the ring structure formed by the positioning plate and the adjusting plate. A filling assembly is arranged inside the positioning plate and the adjusting plate to support the inner wall of the ring structure. The filling assembly deforms along with the ring structure.

[0007] As an improvement of the above technical solution, the supporting assembly comprises a bottom plate and a top plate. A plurality of extrusion shafts are arranged on the surface of the bottom plate. A plurality of connecting shafts are threadedly connected to the surface of the top plate. An arc-shaped block is rotatably connected to the outer side of the connecting shaft. The connecting line of the outer edge of the arc-shaped block forms a circle. The extrusion shafts are arranged on the side of the arc-shaped block protruding outward. The bottom plate and the top plate are arranged in parallel.

[0008] As an improvement of the above technical solution, the bottom plate is rotated to drive the extrusion shafts to extrude the arc-shaped block. The arc-shaped block is rotated along the connecting shaft to adjust the radius of the ring structure formed by the positioning plate and the adjusting plate.

[0009] As an improvement of the above technical solution, a connecting ring is arranged at the center of the end surface of the bottom plate. A positioning ring is arranged at the center of the end surface of the top plate. The connecting ring is nested on the outer side of the positioning ring. The middle shaft penetrates the positioning ring.

[0010] As the improvement of the above technical scheme, the outer side of the middle shaft is provided with a plurality of shaft sleeves, and the positioning ring is threadedly connected to the outer surface of the shaft sleeve.

[0011] As the improvement of the above technical scheme, one side of the positioning plate is provided with a mounting block, and the mounting block is fixed to the surface of the top plate near one side of the top plate.

[0012] As the improvement of the above technical scheme, the positioning plate is integrally formed with one end of the adjusting plate, an inner cavity is formed in the end of the positioning plate away from the adjusting plate, the end of the adjusting plate away from the positioning plate has an insertion part, and the insertion part is inserted into the inner cavity.

[0013] As the improvement of the above technical scheme, the arc-shaped block has an arc-shaped part at the end away from the connecting shaft, and the edge lines of a plurality of the arc-shaped parts form a circle.

[0014] As the improvement of the above technical scheme, the two ends of the middle shaft are provided with connecting assemblies, and the connecting assemblies are detachably fixed to the mounting frame.

[0015] The beneficial effects of the present application are as follows:

[0016] The extrusion ring is provided to perform extrusion, that is, unlike the pressure roller, the extrusion effect is formed by the detachable extrusion ring. Since the extrusion ring is detachable, the position of the extrusion ring can be adjusted according to the needs during actual use, so that extrusion can be generated only for the curved part, thereby ensuring the effect of clamping and correcting.

[0017] Further, the filling assembly is arranged inside to provide support. Since one end of the adjusting plate is inserted into the inside of the positioning plate, the radius of the entire extrusion ring can be adjusted, so that the distance between the two extrusion rings can be controlled without disassembling the mounting frame, thereby achieving the purpose of adaptive adjustment according to different plate specifications, and the use is more convenient.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0023] The existing structure is usually operated by a press roller or the like, but the surface of the press roller is a flat roller body, while the surface of the plate may have certain grooves, in which case the operation by the press roller may cause the grooves of the plate to bend, and the purpose of correcting the plate cannot be achieved.

[0024] In order to solve the above problems, please refer to Figures 1-2 , a metal plate clamping and correcting device is provided, which comprises at least two groups of mounting frames 10 arranged on the same horizontal plane and a shaft 20 rotatably connected in the mounting frame 10.

[0025] Specifically, the outer side of the shaft 20 is detachably provided with a plurality of extrusion rings 40, the extrusion ring 40 comprises a positioning plate 41 and an adjusting plate 42, the positioning plate 41 and the adjusting plate 42 are connected end to end to form a ring structure, one end of the adjusting plate 42 is inserted into the inside of the positioning plate 41 to adjust the radius of the ring structure formed by the positioning plate 41 and the adjusting plate 42, the inside of the positioning plate 41 and the adjusting plate 42 is provided with a filling assembly for supporting the inner wall of the ring structure, and the filling assembly deforms with the ring structure.

[0026] The scheme described in the present embodiment relies on at least two groups of mounting frames 10, taking two groups of mounting frames 10 as an example, two shafts 20 can rotate, so that when the plate is pushed down from the upper part, the extrusion rings 40 on both sides will extrude the surface of the plate to a certain extent, which can straighten and correct the bent part of the plate. Since the extrusion rings 40 are in a detachable state, the extrusion rings 40 can be arranged at appropriate positions according to needs, so that the extrusion rings 40 can only be pressed and corrected for the bent part, and the application range is wider.

[0027] Further, the radius is adjusted by the positioning plate 41 and the adjusting plate 42 connected end to end, when the adjusting plate 42 is inserted into the inside of the positioning plate 41, the radius of the annular structure formed by the combination of the positioning plate 41 and the adjusting plate 42 is reduced, in this way, the distance between the two extrusion rings 40 is reduced, when the adjusting plate 42 is pulled out from the inside of the positioning plate 41, the overall radius is lengthened.

[0028] In one embodiment, referring to Figure 2 , the support assembly comprises a bottom plate 43 and a top plate 44, the surface of the bottom plate 43 is provided with a plurality of extrusion shafts 431, the surface of the top plate 44 is threadedly connected with a plurality of connecting shafts 441, the outer side of the connecting shaft 441 is rotatably connected with an arc block 45, the connecting line of the outer edge of the arc block 45 forms a circle, the extrusion shaft 431 is arranged on the side of the arc block 45 protruding outward, and the bottom plate 43 and the top plate 44 are arranged in parallel.

[0029] The bottom plate 43 is rotated to drive the extrusion shaft 431 to extrude the arc block 45, and the arc block 45 is rotated along the connecting shaft 441 to adjust the radius of the annular structure formed by the positioning plate 41 and the adjusting plate 42.

[0030] By rotating the bottom plate 43, the extrusion of the arc block 45 by the extrusion shaft 431 is controlled, and the arc blocks 45 subjected to extrusion move in the same direction. Due to the arc-shaped surface, although the angle deviation is generated, the circular distribution can still be ensured. In this way, the positioning plate 41 and the adjusting plate 42 on the outer side in the form of a circular ring can always be attached to the outer surface of the arc block 45 in the form of a circular distribution. In this way, stable support effect is formed on the positioning plate 41 and the adjusting plate 42. When the whole extrusion ring 40 is in contact with the curved part of the plate, the arc block 45 in the inside can provide support. The connecting shaft 441 is screwed with the bottom plate 43 and the top plate 44 in a threaded manner, so as to generate extrusion on the arc block 45, and the stability of the arc block 45 can still be ensured after the position adjustment of the arc block 45. Only the connecting shaft 441 needs to be loosened during each adjustment.

[0031] In this way, different radius circular edges can be realized by the arc blocks 45 in different states when the bottom plate 43 is rotated. In this way, such circular edges can be in contact with the inner wall of the adjusting plate 42 and the positioning plate 41. Since the extrusion ring 40 is extruded in a rotating manner, the actual force receiving part is the arc block 45 in the inside. In this way, the overall state of the extrusion ring 40 can be maintained as long as the adjusting plate 42 is inserted into the inside of the positioning plate 41.

[0032] In one embodiment, referring to Figure 2The end surface of the bottom plate 43 is provided with a connecting ring 432, the end surface of the top plate 44 is provided with a positioning ring 442, the connecting ring 432 is nested outside the positioning ring 442, and the middle shaft 20 penetrates the positioning ring 442.

[0033] The nested arrangement between the connecting ring 432 and the positioning ring 442 limits the rotation center of the entire shaft body, so that the center positions of the bottom plate 43 and the top plate 44 are always located at the ring center position of the positioning ring 442.

[0034] In an embodiment, referring to Figure 2 The outer side of the middle shaft 20 is provided with a plurality of shaft sleeves 30, and the positioning ring 442 is threadedly connected to the outer surface of the shaft sleeve 30.

[0035] The shaft sleeve 30 is used to provide additional connection, so as to avoid the need to replace the entire middle shaft 20 when the surface threads of the middle shaft 20 are damaged. When the shaft sleeve 30 is used for connection, the shaft sleeve 30 can be bolted or keyed to ensure the detachability and adjustability of the structure. Thus, when the surface threads of the shaft sleeve 30 are damaged later, the shaft sleeve 30 can be directly removed and replaced, which ensures the replaceability of the structure.

[0036] In an embodiment, referring to Figure 3 One side of the positioning plate 41 is provided with a mounting block 412, and the mounting block 412 is fixed to the surface of the top plate 44 close to one side of the top plate 44.

[0037] The mounting block 412 is used to fix the top plate 44 and the positioning plate 41, so as to ensure the position stability of the positioning plate 41 and the adjusting plate 42, and avoid the falling of the adjusting plate 42 and the positioning plate 41 caused by unstable extrusion of the arc-shaped block 45.

[0038] In an embodiment, referring to Figure 2 One end of the positioning plate 41 and the adjusting plate 42 is integrally formed, the other end of the positioning plate 41 away from the adjusting plate 42 is provided with an inner cavity 411, the other end of the adjusting plate 42 away from the positioning plate 41 is provided with an insertion portion 421, and the insertion portion 421 is inserted into the inner cavity 411.

[0039] The inner cavity 411 is used to receive the insertion portion 421, so as to form stable connection, and the insertion portion 421 and the inner cavity 411 can be arranged at an outer position, so as to reduce the thickness difference between the insertion portion 421 and the positioning plate 41 and the use influence caused by the thickness difference.

[0040] In an embodiment, referring to Figure 2The arc-shaped block 45 has an arc-shaped part 46 at one end away from the connecting shaft 441, and the edges of the arc-shaped parts 46 form a circle. The two ends of the central shaft 20 are provided with connecting assemblies 50, which are detachably fixed to the mounting frame 10

[0041] The arc-shaped part 46 is separately arranged here to reduce the edges of the arc-shaped block 45, so that the edges of the formed circle are smoother, and the circular structure formed by the arc-shaped block 45 is more closely fitted to the ring-shaped positioning plate 41 and the adjusting plate 42. The arc-shaped part 46 in this connected state can reduce damage to the inner walls of the positioning plate 41 and the adjusting plate 42 caused by extrusion.

[0042] The above examples are only used to illustrate the technical solutions of the present application, and not to limit them.
