Description

Technical Field

[0001] This utility model relates to the technical field of bending devices for server rack hardware, and in particular to a bending device for server rack hardware. Background Technology

[0002] Traditional sheet metal bending, especially for cabinet-type sheet metal parts, often suffers from low efficiency, inconvenient operation, and difficulty in guaranteeing precision. It mainly relies on manual labor or general-purpose bending equipment. The former is labor-intensive and slow, and manual application of force is difficult to maintain evenly and consistently, easily leading to inconsistent bending angles, workpiece positioning misalignment, or surface indentation deformation, affecting product quality. While the latter is partially automated, it may have complex structures, higher costs, or lack optimized design for specific shapes and sizes of cabinet sheet metal parts, resulting in an inefficient and inaccurate bending process.

[0003] Some existing bending mechanisms may have limitations in their structural design. For example, the mechanism used to clamp the workpiece may lack sufficient force or have unstable movement, making the workpiece prone to displacement during bending and directly affecting bending accuracy. The mechanism used to drive the bending action may have an unreasonable power transmission path and angle design, resulting in low driving torque conversion efficiency, affecting bending force and the smoothness of the action, especially for thicker or stronger sheet metal parts. At the same time, the equipment often lacks convenient and reliable positioning and clamping mechanisms, as well as devices for accurately guiding the motion trajectory.

[0004] Furthermore, insufficient automation of the equipment is also a problem. Operation requires significant manual intervention to place workpieces, initiate different steps, or make fine adjustments, increasing operation time and the likelihood of errors. The lack of multi-station or collaborative operation designs also limits the efficiency of batch processing, making it difficult to meet the demands of large-scale production. Utility Model Content

[0008] Two first cylinders are fixedly mounted on the top of the frame. The first cylinders are arranged vertically, and the output ends of the first cylinders face the support frame. The output ends of the first cylinders are connected to the pressure seat. The pressure seat is used to press the sheet metal parts supported on the support frame under the drive of the output ends of the first cylinders.

[0009] Two second cylinders are respectively connected to the bottom of the two support frames. The bottom of the second cylinder is rotatably connected to the rotating seat. The rotating seat is fixedly connected to the bottom of the support frame. The output end of the second cylinder is rotatably connected to the side of the bending block. The extension and retraction of the output end of the second cylinder drives the bending block to rotate around the rotation center of the bending block and the support frame.

[0010] Furthermore, the output end of the second cylinder faces the first cylinder, and the angle formed between the extension / retraction direction of the output end of the second cylinder and the extension / retraction direction of the output end of the first cylinder is an acute angle.

[0011] Furthermore, the pressure seat is located on the other side of the connection between the bending block and the output end of the second cylinder on the bending block.

[0012] Furthermore, a connecting plate is provided on the side of the bending block, and the connecting plate is rotatably connected to the output end of the second cylinder.

[0013] Furthermore, the two first cylinders are arranged in parallel, a guide rod is provided on the support frame, the pressure seat passes through the guide rod, and the guide rod is arranged parallel to the output end of the first cylinder.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Please see Figure 1-2 As shown, this utility model proposes a bending device for cabinet sheet metal parts, which includes a frame 11, a support frame 12, a pressure seat 13, a bending block 14, a rotating seat 15, a first cylinder 21, and a second cylinder 22.

[0023] Two support frames 12 are fixedly mounted at the bottom of the frame 11 and spaced apart. A bending block 14 is rotatably connected to the side of the support frame 12. The two support frames 12, fixed to the bottom of the frame 11, form a stable foundation, while the bending block 14 is rotatably connected to the side of the support frame 12. Two vertically mounted first cylinders 21 are installed at the top of the frame 11, and their outputs drive the pressure seat 13 to move downwards. The pressure seat 13 passes through guide rods 16 on the support frame 12, ensuring smooth vertical movement and effectively pressing the sheet metal parts placed on the support frame 12, achieving precise positioning and reliable fixation of the workpiece.

[0024] Two first cylinders 21 are fixedly mounted on the top of the frame 11. The first cylinders 21 are arranged vertically, with their output ends facing the support frame 12. The output ends of the first cylinders 21 are connected to a pressure seat 13, which is located on the other side of the connection between the bending block 14 and the output end of the second cylinder 22. Driven by the output ends of the first cylinders 21, the pressure seat 13 is used to press the sheet metal parts supported on the support frame 12.

[0025] Two first cylinders 21 are arranged in parallel. A guide rod 16 is provided on the support frame 12. The pressure seat 13 passes through the guide rod 16. The guide rod 16 is arranged in parallel with the output end of the first cylinder 21.

[0026] Two second cylinders 22 are respectively connected to the bottom of two support frames 12. The bottom of the second cylinder 22 is rotatably connected to the rotating seat 15. The rotating seat 15 is fixedly connected to the bottom of the support frame 12. The output end of the second cylinder 22 is rotatably connected to the side of the bending block 14. A connecting plate 141 is provided on the side of the bending block 14. The connecting plate 141 is rotatably connected to the output end of the second cylinder 22. The extension and retraction of the output end of the second cylinder 22 drives the bending block 14 to rotate around the rotation center of the bending block 14 and the support frame 12.

[0027] The output end of the second cylinder 22 faces the first cylinder 21, and the angle formed between the extension / retraction direction of the output end of the second cylinder 22 and the extension / retraction direction of the output end of the first cylinder 21 is an acute angle. This specific angle design optimizes the force transmission path, improves the efficiency and torque output of the second cylinder 22 driving the bending block 14 to rotate, making the bending action more powerful and stable, and improving the efficiency of sheet metal bending processing.

[0028] Two second cylinders 22 are respectively connected to the bottom of two support frames 12, and their cylinder bodies are rotatably connected to the support frames 12 via rotating seats 15. The output end of the second cylinder 22 is rotatably connected to the side of the bending block 14 via a connecting plate 141. When the second cylinder 22 extends or retracts, its output end drives the bending block 14 to rotate around its rotation center with the support frame 12, completing the bending operation of the sheet metal part. The first cylinder 21 is responsible for vertical clamping, and the second cylinder 22 is responsible for driving the bending block 14 to rotate; the two work together to complete the bending process.

[0029] This device is highly automated, easy and reliable to operate, reduces manual labor intensity, and helps ensure the consistency of bending angles. The guide rod 16 guides the pressure seat 13, the rotating seat 15 connects to the cylinder body of the second cylinder 22, and the connecting plate 141 connects the output end of the second cylinder 22 to the bending block 14. These structural designs together ensure the stability and accuracy of each moving part during the pressing and bending process.
