Description

Technical Field

[0002] A sheet metal bending angle control device is a piece of equipment used to precisely control the bending angle of sheet metal. It ensures that the sheet metal part reaches a predetermined angle during the bending process through the coordinated work of various mechanical and electronic components. For example, a sheet metal bending device with controllable bending angle includes a fixed plate, a support rod, and a bending adjustment mechanism. The bending adjustment mechanism consists of an angle observation device and an adjustment body. Precise angle adjustment is achieved through components such as a rotating shaft, a limit rod, and a fastening nut. This device not only improves production efficiency but also ensures the consistency and accuracy of the bending angle, making it suitable for processing various types of sheet metal parts.

This wear not only affects the accuracy of the bending angle but may also cause the electric cylinder to malfunction, increasing maintenance costs and downtime. Therefore, a sheet metal bending angle control device is proposed to address the above problems. Utility Model Content

[0027] Please see Figure 1-7 This utility model provides a technical solution:

[0028] A sheet metal bending angle control device includes a base 2, a frame 3, a hydraulic rod 4, a bending punch 6, and a hydraulic conveying assembly 7. The hydraulic conveying assembly 7 is fixedly connected to the top of the base 2, and an angle adjustment assembly 8 is fixedly connected to the outside of the hydraulic conveying assembly 7. The hydraulic conveying assembly 7 includes a storage tank 71, with an oil inlet 72 at the left end of the storage tank 71. A first solenoid valve 73 is fixedly connected to the inside of the oil inlet 72 in the storage tank 71. A self-priming pump 74 is fixedly connected to the left side of the storage tank 71, and a central support 75 is fixedly connected to the left end of the self-priming pump 74. A branch channel 76 and a connecting channel 77 are opened at the lower end of the central support 75, and a shaft hole 78 is opened at the upper end of the central support 75. A bending punch is rotatably connected to the inside of the shaft hole 78 in the central support 75. The trough plate 79 and the angle adjustment assembly 8 include a fixed plate 81. A first arc-shaped cylinder 82 is fixedly connected to one side of the fixed plate 81. A first arc-shaped groove 83 is opened on the inner side of the first arc-shaped cylinder 82. The inner side of the first arc-shaped groove 83 of the first arc-shaped cylinder 82 fits against the outer side of the second arc-shaped cylinder 84. A rubber ring 85 is fixedly connected to the outer side of the second arc-shaped cylinder 84. A second arc-shaped groove 86 is opened on the inner side of the second arc-shaped cylinder 84 near the hydraulic conveying assembly 7. The bottom ends of the storage box 71 and the middle solid platform 75 are fixedly connected to the top end of the base platform 2. One side of the lower end of the second arc-shaped cylinder 84 is fixedly connected to the outer side of the middle solid platform 75. One side of the fixed plate 81 is fixedly connected to one side of the bent trough plate 79.

[0029] As a further implementation of this solution, a controller 1 is fixedly connected to the front end of the base 2, a frame plate 3 is fixedly connected to the top of the base 2, a hydraulic rod 4 is fixedly connected to the inner side of the upper end of the frame plate 3, and a bending punch 6 is fixedly connected to the bottom end of the hydraulic rod 4. The controller 1, the second solenoid valve 87, the first solenoid valve 73, the self-priming pump 74 and the hydraulic rod 4 are electrically connected. A guide rod 5 is fixedly connected to the top of the base 2, and the top end of the guide rod 5 is fixedly connected to one side of the upper end of the frame plate 3. A through hole is opened on the inner side of the bending punch 6 near the guide rod 5. The guide rod 5 is slidably connected to the inner side of the bending punch 6. With the above settings, the controller 1 can control the hydraulic rod 4 to push the bending punch 6 to perform stamping work on the sheet metal. Through the orderly control of the controller 1, the angle adjustment effect of the two bending slot plates 79 can be achieved.

[0030] As a further implementation of this solution, the storage tank 71 is hollow inside, and the oil inlet 72 passes through the left end of the storage tank 71. The left end of the oil inlet 72 is connected to the inside of the water pipe at the right end of the self-priming pump 74. The bottom end of the self-priming pump 74 is fixedly connected to the upper end of the base 2. With the above arrangement, it is convenient to output the hydraulic oil inside the storage tank 71 through the self-priming pump 74, and at the same time, the hydraulic oil can be returned to the inside of the storage tank 71 to achieve the effect of circulating the hydraulic oil.

[0031] As a further implementation of this scheme, the connecting channel 77 passes through the right end of the central platform 75 and is connected to the branch channel 76. The front end of the branch channel 76 passes through the inner side of the central platform 75. The test tube at the left end of the self-priming pump 74 is connected to the inner side of the connecting channel 77 opened in the central platform 75. There are two branch channels 76. The left and right ends of the bending groove plate 79 are fixed with shaft columns. The front end of the shaft column of the bending groove plate 79 is installed inside the shaft hole 78. The second arc groove 86 opened in the second arc cylinder 84 is connected to the branch channel 76. There are multiple angle adjustment components 8. The front and rear ends of the central platform 75 are fixed with angle adjustment components 8. Through the above settings, by controlling the opening or closing of the second solenoid valve 87, the direction of hydraulic oil delivery can be controlled, thereby pushing the designated bending groove plate 79 to adjust the bending angle through the angle adjustment components 8.

[0032] As a further implementation of this solution, the first arc-shaped groove 83 and the second arc-shaped cylinder 84 are both hollow arc-shaped bodies. The center of the first arc-shaped groove 83 coincides with the center of the second arc-shaped cylinder 84. The center of the first arc-shaped groove 83 is on the same horizontal line as the axis of the shaft hole 78. The outer side of the rubber ring 85 is in contact with the inner side of the first arc-shaped groove 83 opened in the first arc-shaped cylinder 82. The second arc-shaped groove 86 opened in the second arc-shaped cylinder 84 is connected to the first arc-shaped groove 83 opened in the first arc-shaped cylinder 82. Through the above settings, this adjustment method will greatly reduce mechanical wear when bending sheet metal, improve the service life of the angle adjustment device, and ensure the accuracy of the sheet metal bending angle.

[0033] Workflow: When adjusting the bending angle of the device, the controller 1 controls the first solenoid valve 73 to open, and simultaneously controls multiple second solenoid valves 87 at the front or rear end to open. Then, the self-priming pump 74 is started. At this time, the self-priming pump 74 draws hydraulic oil from the storage tank 71. The hydraulic oil inside the storage tank 71 enters the front or rear branch channel 76 through the oil inlet 72, the inside of the first solenoid valve 73, and the connecting channel 77. It then enters the opened second solenoid valves 87 and 88 through the branch channel 76. Inside the arc-shaped groove 86, the first arc-shaped groove 83 is entered through the second arc-shaped groove 86. At this time, under the thrust of hydraulic oil, multiple fixed discs 81 and the first arc-shaped cylinder 82 rotate around the shaft hole 78. The rubber ring 85 seals the second arc-shaped cylinder 84 and the first arc-shaped cylinder 82. When the fixed discs 81 rotate, they push the bending groove plate 79 to rotate. The shafts at both ends of the bending groove plate 79 rotate inside the shaft hole 78, which limits the rotation of the bending groove plate 79. This is done at the front or rear end. After the angle of the bending groove plate 79 is adjusted, the corresponding multiple second solenoid valves 87 are closed. At this time, hydraulic oil cannot flow, and the position between the first arc cylinder 82 and the second arc cylinder 84 is fixed, thereby achieving the effect of fixing the adjusted angle of the bending groove plate 79. Using the same principle, the other multiple second solenoid valves 87 are opened, and the angle of another bending groove plate 79 is adjusted. After the angles of the two bending groove plates 79 are adjusted, all the first solenoid valves 73 and second solenoid valves 87 are closed, completing the angle adjustment of the bending groove plate 79. When resetting the two bending groove plates 79, all the first solenoid valves 73 and second solenoid valves 87 are opened, and hydraulic oil is drawn from the first arc groove 83 and the second arc groove 86 by the self-priming pump 74, thereby achieving the resetting of the two bending groove plates 79 and facilitating the adjustment of the bending angle again. This adjustment method greatly reduces mechanical wear when bending sheet metal, increases the service life of the angle adjustment device, and ensures the accuracy of the sheet metal bending angle.

[0034] When bending sheet metal, the sheet metal is placed between two bending slot plates 79. The controller 1 controls the hydraulic rod 4 to push the bending punch 6 downward. The bending punch 6 slides on the outside of the guide rod 5 to improve the stability of the bending punch 6 during movement. The bending punch 6 presses down on the sheet metal, and the bending effect of the sheet metal is achieved through the cooperation of the two bending slot plates 79.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
