Description

Technical Field

[0001] The utility model relates to the technical field of bending, and more particularly to a bending device suitable for copper sheets. Background Art

[0002] A press brake is a type of mechanical equipment widely used in the metalworking industry, specifically designed for the precise bending of metal sheets and profiles. Using a hydraulic, mechanical, or servo motor power source, it drives an upper die (ram) to move up and down or left and right relative to a lower die (worktable), cold-bending the metal workpiece placed between them to a predetermined angle and shape. Press brakes offer a compact structure, ease of operation, and high precision, enabling them to efficiently bend a variety of complex sheet metal shapes. They are widely used in industries such as construction, automotive, shipbuilding, aviation, home appliances, and furniture.

[0003] The bending of copper sheets is mostly completed using a bending machine. Then, when a cylinder needs to be bent from a copper sheet, most existing bending machines need to use multiple molds and perform multiple bending operations to produce the cylinder, resulting in low bending efficiency. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention aims to provide a bending device suitable for copper sheets.

[0005] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: a bending device suitable for copper sheets, comprising a base and a driving mechanism;

[0006] The base is fixedly connected to a first bracket and a second bracket, the first bracket is fixedly connected to a lower mold, the second bracket is mounted with a hydraulic cylinder, the piston rod of the hydraulic cylinder is fixedly connected to a bridge, and the bridge is rotatably connected to an upper mold;

[0007] The driving mechanism is arranged on the bridge frame, and is used for driving the upper mold to rotate.

[0008] Preferably, the driving mechanism includes a dual-shaft motor, gears and gear rings. The dual-shaft motor is installed on a bridge frame. Gears are fixedly connected to the output shafts at both ends of the dual-shaft motor. The two gears are meshed with gear rings, and the two gear rings are fixedly connected to the two ends of the upper mold.

[0009] Preferably, a third bracket is fixedly connected to the bridge frame, an upper clamping plate is fixedly connected to the third bracket, and a lower clamping plate adapted to the upper clamping plate is fixedly connected to the first bracket.

[0010] Preferably, a plurality of guide rods are fixedly connected to the bridge frame, and the plurality of guide rods are all slidably connected to the second bracket.

[0011] Preferably, a positioning plate is fixedly connected to the side wall of the second bracket.

[0012] Preferably, the two gear rings are coaxial with the upper die.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Place the copper sheet between the upper die and the lower die, and use the hydraulic cylinder to drive the upper die downward. The copper sheet between the upper and lower dies will be squeezed and bent into the shape of a half cylinder. Then, the driving mechanism drives the upper die to rotate. As the upper die rotates around the lower die, a complete cylindrical shape can be bent on the copper sheet. This solves the problem of the existing technology that requires multiple bends to bend a cylinder, and effectively improves the bending efficiency.

[0015] 2. When the hydraulic cylinder drives the upper die to move downward through the bridge, the bridge drives the upper clamping plate to move downward through the third bracket, so that the upper clamping plate cooperates with the lower clamping plate and clamps the copper sheet, thereby ensuring that the copper sheet will not be displaced during the bending process.

[0025] Reference Figures 1 to 3 , the utility model provides a technical solution: a bending device suitable for copper sheets, comprising a base 1 and a driving mechanism;

[0026] The base 1 is fixedly connected to a first bracket 2 and a second bracket 3, and the first bracket 2 is fixedly connected to a lower mold 4. Figure 2 The lower mold 4 is in the shape of a circular tube. A hydraulic cylinder 5 is mounted on the second bracket 3. A bridge 6 is fixedly connected to the piston rod of the hydraulic cylinder 5. An upper mold 7 is rotatably connected to the bridge 6. Figure 1 , the hydraulic cylinder 5 can drive the upper mold 7 to move up and down through the bridge 6;

[0027] The driving mechanism is arranged on the bridge 6, and the driving mechanism is used to drive the upper mold 7 to rotate;

[0028] like Figure 2, place the copper sheet between the upper die 7 and the lower die 4, and drive the upper die 7 downward through the hydraulic cylinder, so that the copper sheet between the upper die 7 and the lower die 4 will be squeezed and bent into the shape of a half cylinder; then the driving mechanism drives the upper die 7 to rotate clockwise (at this time, the upper die 7 and the lower die 4 are coaxial), and while the upper die 7 rotates around the lower die 4, a complete cylindrical shape can be bent on the copper sheet, thereby solving the problem that multiple bendings are required to bend a cylinder in the prior art, and effectively improving the bending efficiency;

[0029] When one end of the upper die 7 rotates to contact with the first bracket 2, it stops rotating, and then the upper die 7 is driven to reset by the driving mechanism, and then the upper die 7 is driven to reset by the hydraulic cylinder 5. The bent copper sheet can be pulled out through one end of the lower die 4.

[0030] Specifically, the driving mechanism includes a double-output shaft motor 8, a gear 9 and a gear ring 10. The double-output shaft motor 8 is installed on the bridge 6. The output shafts at both ends of the double-output shaft motor 8 are fixedly connected with gears 9. The two gears 9 are respectively engaged with gear rings 10. The two gear rings 10 are respectively fixedly connected to the two ends of the upper mold 7. Figure 3 The output shafts at both ends of the double-output shaft motor 8 can drive the two gears 9 to rotate synchronously, and the two gears 9 respectively drive the two gear rings 10 to rotate synchronously, and the two gear rings 10 can drive the upper mold 7 to rotate.

[0031] Specifically, the bridge 6 is fixedly connected to a third bracket 11, the third bracket 11 is fixedly connected to an upper splint 12, and the first bracket 2 is fixedly connected to a lower splint 13 adapted to the upper splint 12. Figure 1 and Figure 2 When the hydraulic cylinder 5 drives the upper die 7 to move downward through the bridge 6, the bridge 6 drives the upper clamping plate 12 to move downward through the third bracket 11, so that the upper clamping plate 12 cooperates with the lower clamping plate 13 and clamps the copper sheet, thereby ensuring that the copper sheet will not be displaced during the bending process.

[0032] Specifically, a plurality of guide rods 14 are fixedly connected to the bridge 6, and the plurality of guide rods 14 are all slidably connected to the second bracket 3. Figure 1 , multiple guide rods 14 can make the bridge 6 more stable during the up and down movement.

[0033] Specifically, a positioning plate 15 is fixedly connected to the side wall of the second bracket 3. Figure 1 When placing the copper sheet between the upper die 7 and the lower die 4, one end of the copper sheet is pressed against the positioning plate 15, so that the copper sheet can be placed in the correct position, which helps to quickly position the copper sheet.

[0034] Specifically, the two gear rings 10 are coaxial with the upper die 7 .

[0035] Working principle: Place the copper sheet between the upper die 7 and the lower die 4, and the upper die 7 is driven downward by the hydraulic cylinder. The copper sheet between the upper die 7 and the lower die 4 will be squeezed and bent into the shape of a half cylinder.

[0036] The output shafts at both ends of the double-output shaft motor 8 can drive the two gears 9 to rotate synchronously, and the two gears 9 respectively drive the two gear rings 10 to rotate synchronously. The two gear rings 10 can drive the upper mold 7 to rotate. While the upper mold 7 rotates around the lower mold 4, it can bend a complete cylindrical shape on the copper sheet, thereby solving the problem in the existing technology that multiple bendings are required to bend a cylinder, and effectively improving the bending efficiency.
