Description

Technical Field

[0001] This utility model relates to the field of metal plate bending technology, specifically to a metal panel bending device. Background Technology

[0002] In the production and processing of metal sheets, due to the specific requirements of the products, it is often necessary to bend the metal sheets at a certain angle, which requires the use of corresponding bending devices.

[0003] Chinese Patent Publication No. CN220092621U discloses a bending device for metal sheets, including a lower die base. An auxiliary plate is fixedly mounted on the top of the front of the lower die base. A fixing block is fixedly mounted on the middle of the top of the auxiliary plate away from the lower die base. A threaded rod is threaded in the middle of the fixing block, and a knob is fixedly connected to one end of the threaded rod. This invention relates to a bending device for metal sheets. By rotating the knob, the threaded rod is rotated, which in turn moves the positioning rod back and forth, causing the pointer to move back and forth until the value of the scale line pointed to by the pointer is equal to the distance between the bending point of the metal sheet and one side of the metal sheet. At this time, the distance between the positioning rod and the center of the bending groove is equal to the distance between the bending point of the metal sheet and one side of the metal sheet. The corresponding side of the metal sheet is then pressed against the positioning rod, and the bending point of the metal sheet is located directly below the bending block, thereby achieving precise positioning of the bending point of the metal sheet.

[0004] The aforementioned device uses a bending block to bend metal sheets. However, different metal sheets require different bending angles, and the device cannot precisely adjust the bending angle during operation. Utility Model Content

[0005] To address the aforementioned issues, a metal panel bending device is provided. By installing a protractor on the top of the bending table, with the center point of the protractor located between the placement plate and the bending plate, the angle changes of the metal panel during the bending process can be monitored in real time and accurately. This ensures that metal panels with different bending angle requirements can be bent precisely, thereby improving the accuracy of metal panel bending processing and the product qualification rate.

[0006] To address the problems of existing technologies, this utility model provides a metal panel bending device, including a bending table. A placement plate for placing a metal plate is provided on the top of the bending table. A bending plate for bending the metal plate is rotatably mounted on one side of the placement plate. A protractor for measuring the bending angle of the metal plate is also provided on the top of the bending table. A drive frame is provided at the bottom of the bending table, and a drive assembly for driving the bending plate is provided inside the drive frame. Positioning components for positioning the metal plate are provided on the top of both the placement plate and the bending plate.

[0007] Preferably, the drive assembly includes a hydraulic rod disposed inside the drive frame, a push block is disposed at the movable end of the hydraulic rod, a top block is rotatably disposed at the top of the push block, and one end of the top block is rotatably connected to the bottom of the bending plate.

[0008] Preferably, the top of the bending table is provided with a rectangular groove for the top block to move.

[0009] Preferably, guide rods are provided on both sides of the inner side of the drive frame, and the push block is movably disposed outside the guide rods.

[0010] Preferably, the positioning assembly includes a sliding seat slidably disposed on the top of the placement plate and the bending plate, a positioning screw threaded on the top of the sliding seat, and a positioning plate rotatably disposed on the bottom of the positioning screw for positioning the metal plate.

[0011] Preferably, the top of the sliding seat is also movably provided with symmetrical limiting rods, the bottom of which is connected to the top of the positioning plate.

[0012] Preferably, the bottom of the positioning plate is provided with an anti-slip pad to prevent slippage.

[0013] Preferably, the center point of the protractor is located between the placement plate and the bending plate.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. By setting a protractor on the top of the bending table, with the center point of the protractor located between the placement plate and the bending plate, the angle change of the metal plate during the bending process can be monitored in real time and accurately, ensuring that metal plates with different bending angle requirements can be bent accurately, thereby improving the accuracy of metal plate bending processing and the product qualification rate.

[0016] 2. The device achieves reliable positioning of the metal plate through the positioning component. The position of the sliding seat can be adjusted according to the size of the metal plate. Rotating the positioning screw makes the positioning plate press the metal plate tightly. The anti-slip pad at the bottom of the positioning plate can increase friction, prevent the metal plate from sliding, and increase the stability of bending. Attached Figure Description

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 6 As shown, this utility model provides:

[0026] A metal panel bending device includes a bending table 1, a placement plate 2 for placing a metal plate is provided on the top of the bending table 1, a bending plate 4 for bending the metal plate is rotatably provided on one side of the placement plate 2, a protractor 5 for measuring the bending angle of the metal plate is also provided on the top of the bending table 1, a drive frame 6 is provided at the bottom of the bending table 1, a drive assembly for driving the bending plate 4 is provided inside the drive frame 6, and positioning assemblies for positioning the metal plate are provided on the top of both the placement plate 2 and the bending plate 4.

[0027] The metal plate to be bent is placed on the placement plate 2 on the top of the bending table 1. The metal plate is clamped and positioned by the positioning components on the top of the placement plate 2 and the bending plate 4 to prevent the metal plate from shifting during the bending process and to ensure accurate bending position.

[0028] The drive assembly inside the drive frame 6 at the bottom of the bending table 1 is activated, providing power to the bending plate 4, which drives the bending plate 4, which is rotatably connected to one side of the placement plate 2, to rotate around the rotation point.

[0029] During the process of bending the metal plate by rotating the bending plate 4, the protractor 5 located at the top of the bending table 1 monitors the bending angle of the metal plate in real time. The operator can judge whether the required bending angle has been reached based on the reading of the protractor 5, so as to control the drive component to stop working in time and achieve precise bending.

[0030] like Figure 4As shown, the drive assembly includes a hydraulic rod 10 disposed inside the drive frame 6. A push block 8 is disposed at the movable end of the hydraulic rod 10. A top block 7 is rotatably disposed at the top of the push block 8. One end of the top block 7 is rotatably connected to the bottom of the bending plate 4.

[0031] When the bending plate 4 needs to be driven for bending operations, the hydraulic rod 10 inside the drive frame 6 is activated, and the movable end of the hydraulic rod 10 extends, pushing the push block 8 connected to it to move. Since the bottom of the top block 7 is rotatably connected to the top of the push block 8, and the top is rotatably connected to the bottom of the bending plate 4, the movement of the push block 8 will cause the top block 7 to change angle around the rotation connection point with the push block 8 as the base point, thereby pushing the bending plate 4 to rotate upward around the rotation point with the placement plate 2, and finally realizing the bending operation of the metal plate on the placement plate 2; when the bending is completed, the movable end of the hydraulic rod 10 retracts, pulls the push block 8 to move in the opposite direction, and the top block 7 resets accordingly, driving the bending plate 4 back to the initial position for the next bending operation.

[0032] like Figure 4 As shown, a rectangular groove 15 for the top block 7 to move is provided on the top of the bending table 1.

[0033] The rectangular groove 15 on the top of the bending table 1 provides dedicated space for the top block 7 to move, preventing the top block 7 from colliding or rubbing against the bending table 1 during movement, and ensuring that the top block 7 can smoothly push the bending plate 4 to complete the bending action.

[0034] like Figure 4 As shown, guide rods 9 are provided on both sides of the inside of the drive frame 6, and the push block 8 is movably disposed outside the guide rods 9.

[0035] When the hydraulic rod 10 drives the push block 8 to move, since the push block 8 is movably sleeved on the outside of the guide rods 9 on both sides inside the drive frame 6, the guide rods 9 will restrict and guide the movement direction of the push block 8, preventing the push block 8 from deviating or shaking during the movement, ensuring that the push block 8 can move stably along the preset straight direction, thereby ensuring that the top block 7 pushes the bending plate 4 in a precise direction, and finally achieving stable and precise bending of the metal plate.

[0036] like Figure 5 As shown, the positioning assembly includes a sliding seat 3 that is slidably disposed on the top of the placement plate 2 and the bending plate 4. A positioning screw 11 is threaded on the top of the sliding seat 3, and a positioning plate 12 for positioning the metal plate is rotatably disposed on the bottom of the positioning screw 11.

[0037] According to the size of the metal plate and the bending requirements, push the sliding seat 3 to slide on the top of the placement plate 2 and the bending plate 4, adjust the sliding seat 3 to a suitable positioning position, so that the positioning plate 12 can correspond to the area of ​​the metal plate that needs to be positioned.

[0038] Rotate the positioning screw 11 at the top of the sliding seat 3. Since the positioning screw 11 is threadedly connected to the sliding seat 3, the rotation will drive the positioning plate 12 at the bottom to move downward until the positioning plate 12 is in close contact with the surface of the metal plate, thus firmly fixing the metal plate on the placement plate 2 and the bending plate 4, preventing the metal plate from shifting during the bending process.

[0039] like Figure 5 As shown, a symmetrical limiting rod 14 is also movably provided on the top of the sliding seat 3, and the bottom of the limiting rod 14 is connected to the top of the positioning plate 12.

[0040] As the positioning screw 11 rotates and drives the positioning plate 12 to move up and down, the symmetrical limiting rod 14, which is connected to the top of the positioning plate 12 and movably passes through the sliding seat 3, will also move up and down accordingly. The limiting rod 14 can restrict the movement direction of the positioning plate 12, prevent the positioning plate 12 from rotating or shifting during the up and down movement, and ensure that the positioning plate 12 always maintains a horizontal state and makes stable contact with the metal plate, thereby improving the stability and reliability of positioning.

[0041] like Figure 5 As shown, the bottom of the positioning plate 12 is provided with an anti-slip pad 13 to prevent slippage.

[0042] When the positioning plate 12 moves downward under the drive of the positioning screw 11 and comes into contact with the surface of the metal plate, the anti-slip pad 13 at the bottom of the positioning plate 12 will directly adhere to the surface of the metal plate. The anti-slip pad 13 is made of a material with a high coefficient of friction, which can increase the friction between the positioning plate 12 and the metal plate, effectively preventing the metal plate from sliding relative to the positioning plate 12 due to the bending force during the bending process.

[0043] like Figure 1 As shown, the center point of the protractor 5 is located between the placement plate 2 and the bending plate 4.

[0044] Since the center point of the protractor 5 coincides with the rotation connection point of the placement plate 2 and the bending plate 4, when the bending plate 4 drives the metal plate to rotate and bend around the rotation point, the bending angle of the metal plate is consistent with the rotation angle of the bending plate 4 relative to the placement plate 2. The protractor 5 can accurately measure the rotation angle of the bending plate 4. By observing the scale on the protractor 5 corresponding to the edge of the bending plate 4 or the metal plate, the operator can directly read the bending angle of the metal plate, thereby accurately judging whether the bending angle meets the requirements. This facilitates timely control of the drive component to stop working and achieves precise control of the bending angle of the metal plate.

[0045] The above embodiments merely illustrate one or several implementation methods of the metal panel bending device of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model.
