Description

Technical Field

[0001] This utility model belongs to the field of edge bending processing technology of power distribution cabinet plates, and specifically relates to a bending device for power distribution cabinet plates. Background Technology

[0002] In the manufacturing process of electrical distribution cabinets, it is usually necessary to fold the edges of multiple side panels, then join these side panels together, and finally weld them to form the cabinet body. The accuracy of the folding position has a crucial impact on the structural strength and overall assembly precision of the cabinet.

[0003] However, in existing technologies, the bending equipment used for bending distribution cabinet panels often has a relatively fixed structure. This fixed structure makes it difficult for the equipment to flexibly adjust the bending position according to the width of different panels. When dealing with panels of different widths, operators need to spend a lot of time and effort to readjust the equipment or replace special molds, which not only seriously affects production efficiency but may also lead to poor bending quality due to inaccurate bending position adjustment, increasing scrap rate and production costs. Therefore, a bending equipment for distribution cabinet panels is provided to solve the above-mentioned technical problems. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a power distribution cabinet plate bending device to solve the problems of the existing bending devices, which have a relatively fixed structure, making it difficult to flexibly adjust the bending position according to the width of the plate, resulting in low production efficiency, poor plate bending quality and increased production costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bending device for electrical distribution cabinet panels includes a processing table. The upper surface of the processing table is provided with two adjustable mounting blocks. The two blocks are used to horizontally support the panel from the bending point. A lifting mechanism is installed above the processing table. The lifting mechanism contains two Z-shaped pressure blocks with adjustable spacing. The lifting mechanism drives the two Z-shaped pressure blocks to move down and cooperate with the two blocks to laterally bend the panel placed on the blocks.

[0007] In the above technical solution, a plurality of adjusting screw holes for connecting the pad are opened through the table surface of the processing table. The pad is screwed to the corresponding adjusting screw hole and a fixing bolt is installed. The fixing bolt is embedded in the pad.

[0008] In the above technical solution, the lifting mechanism includes a base plate located inside the legs of the processing table. A hydraulic telescopic column is fixedly installed between the center of the upper surface of the base plate and the processing table. Support rods are fixedly installed at the four corners of the base plate. A fixed frame is fixedly installed between the top ends of the four support rods. The two Z-shaped pressure blocks are slidably connected to the fixed frame.

[0009] In the above technical solution, the upper surface of the Z-shaped pressure block is symmetrically fixed with sliding sleeves, which are slidably installed on the outer surface of the fixed frame.

[0010] In the above technical solution, a bidirectional screw rod with positive and negative threads is rotatably installed through the fixed frame. A protrusion is fixedly installed at the middle end of the upper surface of the Z-shaped pressure block. The two protrusions are symmetrically sleeved on the outer surface of the bidirectional screw rod with positive and negative threads, and the protrusions are threadedly connected to the bidirectional screw rod with positive and negative threads. A handwheel is fixedly installed at the left end of the bidirectional screw rod with positive and negative threads.

[0011] In the above technical solution, two lifting columns are symmetrically fixedly installed on the upper surface of the base plate. The lifting columns penetrate the table surface of the processing table. After the base plate of the lifting columns is moved up, it is used to lift the bent plate away from the pad block.

[0012] The present invention provides a bending device for electrical distribution cabinet plates, which, compared with the prior art, has the following advantages:

[0013] This invention utilizes a three-point bending force system formed by adjustable mounting blocks on the processing table and Z-shaped pressure blocks with adjustable spacing in the lifting mechanism. Combined with a rigid transmission mechanism consisting of a hydraulic telescopic column and a support rod, it achieves precise vertical downward pressure. This system not only adapts to the folding requirements of different widths of sheet metal by coordinating the adjustment of the block position and Z-shaped pressure block spacing, avoiding mold changes and repeated adjustments to improve production efficiency, but also ensures accurate folding position through high-precision hydraulic motion control, reducing sheet metal deformation and scrap rate. Furthermore, after processing, the lifting column automatically lifts the sheet metal away from the block as the hydraulic telescopic column retracts, simplifying the disassembly process and reducing labor intensity. In addition, the purely mechanical adjustment method is easy to operate, requires no special molds, effectively reduces production costs, improves sheet metal utilization, and enhances enterprise economic benefits.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-3 This utility model provides a technical solution:

[0020] A bending device for power distribution cabinet panels includes a processing table 1. The upper surface of the processing table 1 is provided with two adjustable mounting blocks 2. The two blocks 2 are used to horizontally support the panel from the bending point. A lifting mechanism 3 is installed above the processing table 1. The lifting mechanism 3 is equipped with two Z-shaped pressure blocks 4 with adjustable spacing. The lifting mechanism 3 drives the two Z-shaped pressure blocks 4 to move down and cooperate with the two blocks 2 to bend the panel placed on the blocks 2 from the side.

[0021] It should be noted that, in combination Figure 1 and Figure 2 As shown, a plurality of adjusting screw holes 12 for connecting pads 2 are provided through the table surface of the processing table 1. Fixing bolts 21 are screwed between the pads 2 and the corresponding adjusting screw holes 12, and the fixing bolts 21 are embedded in the pads 2.

[0022] By setting the Z-shaped pressure blocks 4 within the lifting mechanism 3 to have adjustable spacing, and by moving the Z-shaped pressure blocks 4 downwards via the lifting mechanism 3, a three-point bending force system is formed with the pad block 2, enabling the side bending process of plates of different widths. Through the coordinated adjustment of the position of the pad block 2 and the spacing of the Z-shaped pressure blocks 4, a bending processing system capable of adapting to the edge bending of plates of different widths is constructed.

[0023] In the above technical solution, the lifting mechanism 3 includes a base plate 31, which is located inside the legs of the processing table 1. A hydraulic telescopic column 34 is fixedly installed between the center of the upper surface of the base plate 31 and the processing table 1. Support rods 32 are fixedly installed at the four corners of the base plate 31, and a fixed frame 33 is fixedly installed between the tops of the four support rods 32. Two Z-shaped pressure blocks 4 are slidably connected to the fixed frame 33. During operation, the hydraulic telescopic column 34 drives the base plate 31 to perform linear reciprocating motion in the vertical direction through hydraulic power. Through the rigid transmission mechanism composed of the four corner support rods 32, the fixed frame 33 is driven to synchronously complete the lifting action, thereby enabling the Z-shaped pressure blocks 4 to perform downward pressing and folding operations on the plate on the pad 2. This mechanism, through the synergistic effect of hydraulic drive and rigid support, constructs a folding execution system with vertical motion accuracy.

[0024] Two lugs 11 are welded and fixedly installed on the left and right surfaces of the processing table 1. The support rod 32 passes through the corresponding lug 11 and forms a sliding connection structure with it. The rigid guiding mechanism of the lug 11 ensures that the support rod 32 always maintains a precise straight trajectory during vertical movement, avoiding the shaking of the lifting mechanism 3 due to lateral offset.

[0025] Combination Figure 1 As shown, the upper surface of the Z-shaped pressure block 4 is symmetrically fixed with sliding sleeves 41. The sliding sleeves 41 are slidably installed on the outer surface of the fixed frame 33. The Z-shaped pressure block 4 is slidably connected to the fixed frame 33 through the sliding sleeves 41.

[0026] Combination Figure 1 As shown, a bidirectional screw rod 5 with positive and negative threads is rotatably installed through the fixed frame 33. A protrusion is fixedly installed at the middle end of the upper surface of the Z-shaped pressure block 4. The two protrusions are symmetrically sleeved on the outer surface of the bidirectional screw rod 5 with positive and negative threads, and the protrusions are threadedly connected to the bidirectional screw rod 5 with positive and negative threads. A handwheel 51 is fixedly installed at the left end of the bidirectional screw rod 5 with positive and negative threads. By operating the handwheel 51, the bidirectional screw rod 5 with positive and negative threads can be rotated, thereby driving the two Z-shaped pressure blocks 4 to move inward or outward synchronously. By adjusting the lateral position of the Z-shaped pressure block 4, the downward pressure point during the folding of the board can be precisely controlled, thereby adapting to the folding process requirements of boards with different width specifications.

[0027] After the sheet metal bending process is completed, in order to facilitate the disassembly of the bent sheet metal, two lifting columns 6 are symmetrically fixed on the upper surface of the base plate 31. The lifting columns 6 penetrate the table surface of the processing table 1. After the side bending process of the sheet metal is completed, the hydraulic telescopic column 34 is retracted, which allows the lifting columns 6 to move up with the base plate 31. After the lifting columns 6 continue to rise, they contact the lower surface of the sheet metal to lift the bent sheet metal away from the pad block 2, thus completing the automatic lifting process of the sheet metal.

[0028] When using it, first refer to the width of the material to be bent. Figure 3The handwheel 51 drives the bidirectional screw 5 with both positive and negative threads to rotate, adjusting the two Z-shaped pressure blocks 4 to a suitable distance. Next, according to the side bending requirements of the sheet metal, the two pads 2 are installed at the corresponding adjustment screw holes 12 on the table surface of the processing table 1 with fixing bolts 21 to accurately support the bending part of the sheet metal. During the bending operation, the hydraulic telescopic column 34 is activated to extend it, driving the base plate 31 to move downward in the vertical direction. The four corner support rods 32 drive the fixing frame 33 and the Z-shaped pressure blocks 4 to press down synchronously, forming a three-point force system with the pads 2 to complete the side bending of the sheet metal. After processing is completed, the hydraulic telescopic column 34 retracts, driving the base plate 31 to move upward, so that the fixing frame 33 and the Z-shaped pressure blocks 4 are separated from the sheet metal. At the same time, the lifting column 6 moves upward synchronously with the base plate 31, lifting the bent sheet metal from the pads 2, making it easy for the operator to safely and conveniently pick up the material.
