[0022] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation mode of the utility model will be explained by referring to the drawings.

[0023] The preferred implementation mode of the round bending device for sheet metal machining provided by the utility model is as follows: Figures 1 to 6The device is shown: a round arc folding device for sheet metal processing, including a processing cabinet 1, and a limiting assembly 41 provided on the top of the processing cabinet 1, the limiting assembly 41 includes a bearing table 411 fixedly connected on the top of the processing cabinet 1, the inner wall of the bearing table 411 is hingedly connected with an arc-shaped table 412, the top of the arc-shaped table 412 is slidingly connected with a sheet metal material body 413, the front top of the processing cabinet 1 is fixedly connected with a rectangular block 414, the inner wall of the rectangular block 414 is fixedly connected with a limiting column 415, the outer wall of the limiting column 415 is slidingly connected with a first sliding block 416, the side wall of the first sliding block 416 is fixedly connected with a spring 417, the other end of the spring 417 is fixedly connected with the inner wall of the rectangular block 414, the top of the first sliding block 416 is hingedly connected with a rotating block 418, the other end of the rotating block 418 is hingedly connected with the side wall of the arc-shaped table 412, by arranging the limiting assembly 41, when the sheet metal material body 413 needs to be folded and rounded, the operator places the sheet metal material body 413 on the top of the bearing table 411, realizing supporting the sheet metal material body 413 during the folding and rounding process, when the sheet metal material body 413 is folded and rounded, the middle part of the sheet metal material body 413 will be bent downward, so that the bottom of the sheet metal material body 413 is attached to the inner wall of the arc-shaped table 412, when the sheet metal material body 413 is folded and rounded, the inner wall of the arc-shaped table 412 is pressed, which will cause the arc-shaped table 412 to rotate, after the arc-shaped table 412 rotates, it will pull the rotating block 418 to rotate, during the rotation of the rotating block 418, it will pull the first sliding block 416 to slide along the outer wall of the limiting column 415, and compress the spring 417, thereby limiting the arc-shaped table 412 during rotation, promoting the device to work stably when folding and rounding the sheet metal material body 413, so that the device can uniformly fold and round the middle part of the sheet metal material body 413, improving the processing efficiency of the device.

[0024] The limiting assembly 41 also includes a rectangular platform 4110 fixedly connected to the top side of the processing cabinet 1. A support frame 419 is fixedly connected to the bottom of the rectangular platform 4110. The side wall of the support frame 419 is fixedly connected to the outer wall of the processing cabinet 1. A drive motor 4111 is fixedly connected to the outer wall of the rectangular platform 4110. A lead screw 4112 is fixedly connected to the output end of the drive motor 4111. The other end of the lead screw 4112 is rotatably connected to the inner wall of the rectangular platform 4110. A second slider 4113 is threadedly connected to the outer wall of the lead screw 4112. A clamping block 4114 is fixedly connected to the top of the second slider 4113. The side wall of the clamping block 4114 is slidably connected to the outer wall of the sheet metal body 413. Next, after the operator places the sheet metal material body 413 on the top of the support platform 411, in order to improve the smoothness of the device in bending the sheet metal material body 413 into an arc, it is necessary to clamp and fix the sheet metal material. Then, the operator turns on the drive motor 4111 to make the lead screw 4112 rotate. When the lead screw 4112 rotates, it will cause the second slider 4113 to move along the inner wall of the rectangular platform 4110. During the movement of the second slider 4113, it will cause the clamping block 4114 to move. After the clamping block 4114 is pressed against the outer wall of the sheet metal material body 413, the smoothness of the sheet metal material body 413 in bending into an arc can be achieved.

[0025] A preferred embodiment of the circular arc bending device for sheet metal processing provided by this utility model is, for example... Figures 1 to 6 As shown: A rounding component 42 is also provided on the top of the processing cabinet 1. The rounding component 42 includes a U-shaped bracket 421 fixedly connected to the top of the processing cabinet 1. A cylinder 422 is fixedly connected to the top of the inner wall of the U-shaped bracket 421. A circular extrusion block 423 is fixedly connected to the output end of the cylinder 422. By setting the rounding component 42, after the sheet metal material body 413 is clamped and fixed, the operator opens the cylinder 422, causing the output end of the cylinder 422 to push the circular extrusion block 423 downward. When the circular extrusion block 423 moves downward, it will extrude the inner wall of the sheet metal material body 413, thereby facilitating the rounding of the sheet metal material body 413 and improving the processing effect of the device.

[0026] Furthermore, the bottom of the processing cabinet 1 is fixedly connected with four support legs 2. The four support legs 2 are of equal size and are fixedly connected at the four corners of the bottom of the processing cabinet 1 at equal intervals. By setting four support legs 2, it is easy to achieve stable support for the processing cabinet 1, thereby improving the stability of the device during the processing process.

[0027] Furthermore, the front of the processing cabinet 1 is movably connected to a cabinet door 3 via a hinge. There are two cabinet doors 3, which are symmetrically distributed along the center face of the processing cabinet 1.

[0028] In addition, the inner wall of the second sliding block 4113 is threadedly connected with the outer wall of the lead screw 4112, and the outer wall of the second sliding block 4113 is matched with the inner wall of the rectangular table 4110. By arranging the rectangular table 4110, the lead screw 4112 and the second sliding block 4113, the second sliding block 4113 is limited by the rectangular table 4110, and when the lead screw 4112 rotates, the second sliding block 4113 is moved along the outer wall of the lead screw 4112.

[0029] Working principle: when the metal plate material body 413 needs to be folded and circularly processed, the operator places the metal plate material body 413 on the top of the bearing table 411, so as to support the metal plate material body 413 during the folding and circular processing. When the metal plate material body 413 is folded and circularly processed, the middle part of the metal plate material body 413 is bent downward, so that the bottom of the metal plate material body 413 is attached to the inner wall of the arc-shaped table 412. When the metal plate material body 413 is folded and circularly processed, the inner wall of the arc-shaped table 412 is pressed, so that the arc-shaped table 412 rotates. After the arc-shaped table 412 rotates, the rotating block 418 is pulled to rotate. During the rotation of the rotating block 418, the first sliding block 416 is pulled to slide along the outer wall of the limiting column 415, and the spring 417 is compressed, so as to limit the rotation of the arc-shaped table 412, and make the device work stably when the metal plate material body 413 is folded and circularly processed. The device can uniformly fold and circularly process the middle part of the metal plate material body 413, and the processing efficiency of the device is improved.

[0030] When the operator places the metal plate material body 413 on the top of the bearing table 411, in order to improve the stability of the device when the metal plate material body 413 is folded and circularly processed, the metal plate material needs to be clamped and fixed. Then, the operator starts the driving motor 4111 to drive the lead screw 4112 to rotate. When the lead screw 4112 rotates, the second sliding block 4113 moves along the inner wall of the rectangular table 4110. During the movement of the second sliding block 4113, the clamping block 4114 moves. After the clamping block 4114 extrudes the outer wall of the metal plate material body 413, the metal plate material body 413 is clamped and fixed during the folding and circular processing.

[0031] After the metal plate material body 413 is clamped and fixed, the operator starts the air cylinder 422 to drive the output end of the air cylinder 422 to push the circular extrusion block 423 downward. When the circular extrusion block 423 moves downward, it extrudes the inner wall of the metal plate material body 413, so as to facilitate the folding and circular processing of the metal plate material body 413, and improve the processing effect of the device.

[0032] The above merely illustrates the specific implementation of the present application, and is not intended to limit the scope of the present application. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present application shall fall within the scope of the present application. It should be noted that the components of the present application are not limited to the above overall application, and the technical features described in the specification of the present application can be selected for single use or combined use, therefore, the present application naturally covers other combinations and specific applications related to the present case.
