[0002] like Figure 1 As shown, this is a disc-shaped sheet metal part after processing and bending. During the processing, it is necessary to bend several strips around the disc sheet metal part at a fixed angle to facilitate connection with external components.

[0003] Currently, bending these strips requires workers to use bending equipment, making it difficult to ensure that each strip bends at the same angle, resulting in relatively low processing efficiency and yield.

[0004] It is desirable to provide a peripheral bending device for disc-shaped sheet metal parts in order to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a peripheral bending device for disc-shaped sheet metal parts, which can quickly and accurately bend long strips of disc-shaped sheet metal parts.

[0006] To achieve the above-mentioned utility model objectives, a peripheral bending device for a disc-shaped sheet metal part is provided, including a worktable, a bending mechanism, and an installation mechanism;

[0007] The bending mechanism includes a support base, a rotating shaft, a clamping part, and a handle;

[0008] The support base is fixed to one end of the workbench;

[0009] The rotating shaft is horizontally rotatably mounted on the inner side of the support base;

[0010] The handle is rotatably mounted on the outer side of the support base. The support base is equipped with a gear transmission mechanism. The input end of the gear transmission mechanism is connected to the handle, and the output end of the gear transmission mechanism is connected to the inner end of the rotating shaft.

[0011] The clamping part is located at the outer end of the rotating shaft and is used to clamp the long strip to be bent on the disc-shaped sheet metal part;

[0012] A pointer is provided on the radial side of the curved surface of the rotating shaft, and an angle scale line is provided on the inner side of the support base. The pointer is adapted to the angle scale line.

[0013] The installation mechanism includes a support platform and an upper pressure plate;

[0014] The upper part of the support platform is equipped with a turntable that rotates horizontally.

[0015] The upper pressure plate is fixed to the top of the turntable by bolts.

[0016] Specifically, the clamping part includes a support plate and a limiting plate;

[0017] The support plate is fixed to the front end of the rotating shaft;

[0018] The limiting plate is fixed to the lower surface of the support plate by bolts;

[0019] The front end of the limiting plate is recessed downward to form a step, and the height of the step is adapted to the thickness of the strip to be bent.

[0020] Furthermore, the front end face of the stepped portion is recessed downwards at the middle position to form a limiting groove.

[0021] Preferably, the worktable is provided with a slide groove, and the support platform is slidably disposed on the slide groove and is always directly opposite the clamping part.

[0022] Preferably, the top edge of the turntable is provided with several contoured grooves, each of which corresponds to a long strip after bending.

[0023] This utility model provides a peripheral bending device for a disc-shaped sheet metal part, which has the following advantages compared with the prior art:

[0024] When bending the peripheral strips of a disc-shaped sheet metal part, first place the disc-shaped sheet metal part on the turntable, then cover it with the upper pressure plate and fix the disc-shaped sheet metal part with bolts. Push the support table forward, close to the clamping part, and rotate the turntable so that any strip of the disc-shaped sheet metal part is clamped and limited. The operator rotates the turntable so that the strip is on the step part, then turns the handle to rotate the shaft and make the pointer point to the specified angle. Then rotate the turntable again so that the next strip is clamped and limited. Continue rotating the turntable until all strips have been bent, effectively improving processing efficiency and ensuring a high yield. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 2 As shown, a peripheral bending device for a disc-shaped sheet metal part includes a worktable 1, a bending mechanism, and an installation mechanism.

[0032] The bending mechanism includes a support base 2, a rotating shaft 3, a clamping part 4, and a handle 5; the support base 2 is fixed to one end of the workbench 1; the rotating shaft 3 is horizontally rotatable on the inner side of the support base 2; as shown Figure 4 As shown, the handle 5 is rotatably mounted on the outer side of the support base 2. The support base 2 is equipped with a gear transmission mechanism (not shown in the figure). The input end of the gear transmission mechanism is connected to the handle 5, and the output end of the gear transmission mechanism is connected to the inner end of the rotating shaft 3. With this configuration, the rotating shaft 3 can be rotated by rotating the handle 5. The clamping part 4 is located at the outer end of the rotating shaft 3 and is used to clamp the long strip to be bent on the disc-shaped sheet metal part.

[0033] The rotating shaft 3 has a pointer 6 arranged radially on its curved surface, and the support base 2 has an angle scale line 7 on its inner side, with the pointer 6 matching the angle scale line 7.

[0034] In this embodiment, as Figure 3 As shown, the clamping part 4 includes a support plate 8 and a limiting plate 9; the support plate 8 is fixed to the front end of the rotating shaft 3; the limiting plate 9 is fixed to the lower surface of the support plate 8 by bolts; the front end of the limiting plate 9 is recessed downward to form a step part 10; the height of the step part 10 is adapted to the thickness of the strip to be bent; with this configuration, when the turntable 13 is rotated so that the strip is located on the step part 10, the handle 5 can be rotated to drive the rotating shaft 3 to rotate, and the pointer 6 will point to the specified angle, thus realizing the bending operation of the strip.

[0035] The installation mechanism includes a support platform 11 and an upper pressure plate 12; a turntable 13 is horizontally rotatable on the upper part of the support platform 11; the upper pressure plate 12 is fixed to the top of the turntable 13 by bolts.

[0036] In this embodiment, the workbench 1 is provided with a slide groove 14, and the support platform 11 is slidably disposed on the slide groove 14 and is always directly opposite the clamping part 4; this facilitates loading and unloading.

[0037] like Figure 5As shown, when it is necessary to fix the disc-shaped sheet metal part, first place the disc-shaped sheet metal part 15 on the turntable 13, then cover it with the upper pressure plate 12, and fix the disc-shaped sheet metal part 15 with bolts; push the support table 11 forward to approach the clamping part 4, and rotate the turntable 13 so that any strip of the disc-shaped sheet metal part 15 is limited by the clamping part 4. After the operator rotates the turntable 13 so that the strip is on the step part 10, the handle 5 can be rotated to drive the rotating shaft 3 to rotate, and the pointer 6 points to the specified angle. Then rotate the turntable 13 again so that the next strip is limited by the clamping part. Continue to rotate the turntable 13 until all strips have completed the bending operation.

[0038] In this embodiment, as Figure 3 As shown, the front end face of the stepped part 10 is recessed downward to form a limiting groove 16. When bending is performed, the turntable 13 is rotated first so that a strip on the disc-shaped sheet metal part 15 is aligned with the limiting groove 16. Then the support table 11 is pushed until the strip is limited in the limiting groove 16, and bending can be performed. This further controls the bending angle of the strip more precisely and improves the yield.

[0039] The top edge of the turntable 13 is provided with several contour grooves 17, which correspond one-to-one with the bent strip; this arrangement further ensures the accuracy of the bent strip.

[0040] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
