Technical Field

[0001] This utility model relates to the technical field of power distribution cabinet production equipment, specifically an auxiliary device for bending sheet metal in power distribution cabinet manufacturing. Background Technology

[0002] A distribution cabinet is a device used for power distribution and control, widely used in various buildings and industrial facilities. Its main functions include power distribution and control of electrical equipment, and providing power outage protection in case of overload, short circuit, and leakage. Distribution cabinets typically consist of electrical components such as circuit breakers, switches, contactors, fuses, and transformers. These components work together to distribute power to different loads or equipment. During the manufacturing process, the sheet metal of a distribution cabinet generally needs to be bent into suitable shapes to facilitate subsequent welding or assembly.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1:

[0037] Please see Figure 1 A type of auxiliary equipment for bending sheet metal in the manufacture of power distribution cabinets, comprising:

[0038] Workbench 1, with an installation groove 2 on the right side of the top wall of workbench 1, and a support block 3 is rotatably installed in the installation groove 2. One side of the top wall of the support block 3 is set at a right angle, and the other side of the top wall of the support block 3 is set in an arc.

[0039] Rotating component 4 is mounted on the front wall of worktable 1 and is used to drive support block 3 to deflect.

[0040] Support component 5 is installed inside the workbench 1 and is used to support the bottom of support block 3;

[0041] An inverted L-shaped plate 6 is fixed to the left side of the top wall of the workbench 1, and a clamping assembly 7 is installed on the inverted L-shaped plate 6.

[0042] C-shaped frame 8 is fixed to the bottom right wall of workbench 1. A hydraulic cylinder 9 is fixed to the top wall of C-shaped frame 8. The movable end of the bottom of hydraulic cylinder 9 slides through the top wall of C-shaped frame 8 and is fixed with bending mold 10.

[0043] In this embodiment, the support block 3 is used to bend the metal sheet of the distribution cabinet in conjunction with the bending mold 10. The right-angle end and the arc end on the support block 3 can bend the sheet into a right-angle or arc shape in conjunction with the bending mold 10, which has a wide range of applications. The rotation component 4 can control the rotation of the support block 3, and can rotate the right-angle end or the arc end of the support block 3 to the bending position according to actual needs, so as to bend the sheet into the corresponding shape. The support component 5 is used to support the support block 3 during the bending process, thereby avoiding the support block 3's mounting shaft from breaking due to excessive force. The clamping component 7 is used to limit and fix the metal sheet of the distribution cabinet to be processed. The hydraulic cylinder 9 is used to control the bending mold 10 to move down to perform the bending operation.

[0044] Example 2:

[0045] Please see Figure 2-4 This embodiment provides a technical solution based on Embodiment 1:

[0046] Rotating assembly 4 includes a housing 41, which is fixed to the front wall of the worktable 1, and a worm gear 42 is rotatably installed inside the housing 41.

[0047] The worm gear 42 is fixed on the mounting shaft on one side of the support block 3. The mounting shaft of the support block 3 passes through the front wall of the worktable 1 through the bearing and extends into the housing 41. The worm gear 42 is meshed with the worm 43.

[0048] The worm gear 43 is rotatably mounted between the inner walls of the housing 41, and the top end of the worm gear 43 passes through the top wall of the housing 41 via a bearing and is fixed with a first knob 44.

[0049] The side wall of the worm gear 42 is provided with an arc-shaped limiting groove 46, and the front wall of the worktable 1 is fixed with a limiting rod 45 that cooperates with the arc-shaped limiting groove 46. The limiting rod 45 is slidably installed in the arc-shaped limiting groove 46.

[0050] The arc of the arc-shaped limiting groove 46 is 90°.

[0051] In this embodiment, the rotating component 4 can control the rotation of the support block 3, allowing the right-angled or arc-shaped end of the support block 3 to be rotated to a bending position as needed, facilitating the bending of the corresponding shape of the sheet material. When the support block 3 needs to be rotated, the first knob 44 is rotated, which drives the worm gear 43 to rotate, which in turn drives the worm wheel 42 to rotate, which in turn drives the support block 3 to rotate, thereby rotating the right-angled or arc-shaped end of the support block 3 to a bending position. The arc-shaped groove 46, in conjunction with the limiting rod 45, ensures that the top wall of the support block 3 is horizontal after each rotation.

[0052] The workbench 1 has a cavity 11 inside, the support component 5 is installed in the cavity 11, and a through groove 12 is provided between the top wall of the cavity 11 and the bottom wall of the mounting groove 2.

[0053] The support assembly 5 includes two symmetrically arranged cylinders 51, which are fixed to the bottom wall of the cavity 11. The movable ends of the tops of the two cylinders 51 are fixed with the same support plate 52.

[0054] The clamping assembly 7 includes a threaded post 71, a second knob 72 fixed to the top of the threaded post 71, and a pressure plate 73 screwed through the top wall of the inverted L-shaped plate 6 and rotatably mounted on the bottom of the threaded post 71.

[0055] The sidewalls of the pressure plate 73 are symmetrically fixed with first limiting sliders 74;

[0056] The inner sidewall of the inverted L-shaped plate 6 is symmetrically provided with first limiting grooves 75, and the first limiting slider 74 is slidably installed in the corresponding first limiting groove 75.

[0057] The bending die 10 includes a right-angle plate 101, which is fixed to the movable end of the bottom of the hydraulic cylinder 9. An arc-shaped pressure block 102 is installed at the inner corner of the right-angle plate 101.

[0058] A second limiting slider 103 is fixed to the side wall of the arc-shaped pressure block 102;

[0059] A second limiting groove 104 is provided on the inner side wall of the right-angle plate 101, and a second limiting slider 103 is slidably installed in the second limiting groove 104.

[0060] A threaded knob 105 is screwed through the outer wall of the right-angle plate 101 at the position corresponding to the second limiting slide groove 104.

[0061] In this embodiment, the support component 5 is provided to support the support block 3 during the bending process, thereby preventing the mounting shaft of the support block 3 from breaking due to excessive force. During the bending operation, the control cylinder 51 extends until the support plate 52 is in contact with the bottom wall of the support block 3, thus completing the support of the support block 3.

[0062] The clamping component 7 is used to limit and fix the metal sheet of the distribution cabinet to be processed. When it is necessary to fix the sheet to be bent, the sheet is placed on the top wall of the support block 3, and then the second knob 72 is turned. The second knob 72 drives the threaded column 71 to rotate, and the threaded column 71 drives the pressure plate 73 to move down, thereby clamping and fixing the sheet. The first limiting slider 74 and the first limiting groove 75 can ensure that the pressure plate 73 can move down horizontally, ensuring stable clamping.

[0063] The hydraulic cylinder 9 is used to control the bending die 10 to move downwards for bending operations. The bending die 10 can also be adjusted in shape to cooperate with the support block 3 to bend different shapes of sheet metal. During the bending operation, the hydraulic cylinder 9 extends, causing the bending die 10 to move downwards. The bending die 10, in conjunction with the support block 3, bends the sheet metal. When a right-angled shape is required, simply remove the arc-shaped pressure block 102. Then, rotate the threaded knob 105 to disengage it from the second limit slider 103, allowing the arc-shaped pressure block 102 to be pulled out directly.
