DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] See also Figures 1 to 9 As shown, the utility model provides a bending device for mechanical manufacturing, including a workbench 1, a bending seat 2 is provided on the top of the workbench 1, the bending seat 2 is movably provided on the workbench 1, a threaded driving component for driving the bending seat 2 to move is provided in the workbench 1, the bending seat 2 has multiple groups of bending grooves, a top plate 3 is provided on the workbench 1, a linear drive 4 is provided on the top of the top plate 3, a bending tool 5 is provided at the working end of the linear drive 4, fixing components 6 for fixing the plate are installed on both sides of the bending seat 2 on the workbench 1, and a positioning component 7 for quickly determining the bending point is provided on one side of the workbench 1.

[0028] By placing the plate to be bent in the bending seat 2 on the workbench 1 and using the fixing component 6 to reliably fix the plate, the fixing component 6 can ensure that the plate will not be offset or deformed during the bending process, and use the positioning component 7 to quickly determine the position of the bending point, and drive the threaded driving component according to the required bending size. The threaded driving component drives the bending seat 2 to move precisely on the workbench 1, so that the required bending groove is aligned with the bending tool 5, and the linear drive 4 is started so that its working end drives the bending tool 5 to move downward. The bending tool 5 contacts the plate and applies pressure, so that the plate is bent and deformed under the guidance of the bending groove to achieve a predetermined bending angle.

[0029] See also Figures 1 to 4 As shown, the fixing assembly 6 includes a fixing seat 61, a placement table 62 and an L-shaped clamp 63; the fixing seat 61 is arranged on the workbench 1 and is located on both sides of the bending seat 2; the placement table 62 is arranged on the top of the fixing seat 61; there are two L-shaped clamps 63 that can move toward or away from each other and are arranged on the fixing seat 61, and a relative driving component for driving the L-shaped clamp 63 to move is provided in the fixing seat 61.

[0030] By placing the plate to be bent on the bending seat 2, the part near the bending point of the plate will fit into the placement table 62. By controlling the relative driving components, the two L-shaped clamps 63 move toward each other, gradually approaching and clamping the edge of the plate, so that the L-shaped clamps 63 are in close contact with the plate, and the part near the bending point of the plate is fixed, thereby preventing the plate from shifting during the bending process, resulting in inaccurate bending angles, angle deviations or inconsistencies, and affecting the quality and appearance of the plate.

[0031] See also Figure 4 As shown, the relative driving components include a motor 64, a turntable 65, a hinged rod 66, a slide rail 67 and a slider 68; the motor 64 is arranged at the bottom end of the workbench 1, and the output end of the motor 64 passes through the workbench 1 and extends into the fixed seat 61; the turntable 65 is arranged at the output end of the motor 64; the hinged rod 66 is hingedly arranged on the turntable 65; the slide rail 67 is arranged in the fixed seat 61; the slider 68 is slidably arranged on the slide rail 67, one end of the slider 68 is hinged to the hinged rod 66, and the slider 68 is connected to the L-shaped clamp 63.

[0032] By starting the motor 64 to fix the plate before bending, the motor 64 drives the turntable 65 to rotate synchronously. As the turntable 65 rotates, the angles of the two ends of the hinged rod 66 change. This angle change causes the hinged rod 66 to apply a push or pull force to the slider 68, causing the slider 68 to slide on the slide rail 67. When the slider 68 slides on the slide rail 67, the slider 68 drives the L-shaped clamp 63 to move until it contacts the plate, thereby fixing the plate, achieving precise control of the L-shaped clamp 63, thereby ensuring the stability and processing accuracy of the plate during the bending process.

[0033] See also Figures 5 to 7 As shown, the positioning assembly 7 includes a guide rod 71, a rectangular sleeve 72 and a baffle 73; the guide rod 71 is arranged on one side of the workbench 1, and the surface of the guide rod 71 is also provided with a scale; the rectangular sleeve 72 is slidably set on the guide rod 71, and the rectangular sleeve 72 is provided with a locking component for fixing the position of the rectangular sleeve 72; the baffle 73 is set on the rectangular sleeve 72.

[0034] Before bending, by observing the scale on the guide rod 71, the rectangular sleeve 72 is slid to the corresponding position according to the processing requirements. When the rectangular sleeve 72 slides to the predetermined position, the locking component is used to fix it on the guide rod 71 to ensure that the rectangular sleeve 72 will not slide or deflect due to external force during the bending process. The movement of the rectangular sleeve 72 will drive the baffle 73 to move. After the position of the rectangular sleeve 72 is fixed, the plate to be bent is placed on the bending seat 2 of the workbench 1. At this time, the baffle 73 acts as a reference point to help the operator quickly determine the bending position of the plate.

[0035] See also Figure 6 and Figure 7 As shown, the locking component includes a cavity 74, an insert rod 75, a pull plate 76, a limit block 77, a spring 78 and an insertion slot 79; the cavity 74 is opened in the rectangular sleeve 72; the insert rod 75 is movably arranged in the cavity 74; the pull plate 76 is arranged at one end of the insert rod 75; the limit block 77 is arranged on the insert rod 75; the spring 78 is sleeved on the insert rod 75, one end of the spring 78 abuts against the limit block 77, and the other end of the spring 78 abuts against the inner wall of the cavity 74, the insertion slot 79 is opened on the guide rod 71, and the other end of the insert rod 75 is provided with an abutment portion that can be plugged into the insertion slot 79.

[0036] When the position of baffle 73 needs to be changed according to requirements, by pulling the pull plates 76 on both sides of the rectangular sleeve 72, the pull plates 76 drive the insertion rod 75 to move in the direction away from the insertion groove 79. When the insertion rod 75 moves, it will drive the limit block 77 to move and squeeze the spring 78 through the limit block. When the insertion rod 75 is completely disengaged from the insertion groove 79, the rectangular sleeve 72 can slide along the guide rod 71 and slide the rectangular sleeve 72 to the corresponding position according to processing requirements. The movement of the rectangular sleeve 72 will drive the baffle 73 to move. When the baffle 73 moves to the appropriate position, by loosening the pull plate 76, the spring 78 restores the elastic deformation and drives the abutting portion of the insertion rod 75 to insert into the insertion groove 79, thereby realizing the locking between the rectangular sleeve 72 and the guide rod 71.

[0037] See also Figure 8 and Figure 9 As shown, the threaded drive component includes a threaded rod 21, a moving block 22, a first synchronous wheel 23, a rotating rod 24, a second synchronous wheel 25, a knob 26 and a synchronous belt 27; a rectangular groove is provided on the workbench 1, and the threaded rod 21 is arranged in the rectangular groove; the moving block 22 is arranged on the threaded rod 21; the first synchronous wheel 23 is arranged on the threaded rod 21; a chamber is provided on one side of the rectangular groove in the workbench 1, and the rotating rod 24 is arranged in the chamber, and one end of the rotating rod 24 extends outward through the workbench 1; the second synchronous wheel 25 is provided on the rotating rod 24; the knob 26 is provided at the extended end of the rotating rod 24; and the synchronous belt 27 is sleeved on the first synchronous wheel 23 and the second synchronous wheel 25.

[0038] By rotating the knob 26, the knob 26 drives the rotating rod 24 to rotate, and the rotation of the rotating rod 24 is transmitted to the synchronous belt 27 through the second synchronous wheel 25. The synchronous belt 27 transmits the rotational power of the second synchronous wheel 25 to the first synchronous wheel 23. The first synchronous wheel 23 is fixedly connected to the threaded rod 21, so the threaded rod 21 starts to rotate, and the threaded rod 21 drives the moving block 22 to move, and the moving block 22 drives the bending seat 2 to move, so that the bending seat 2 can be adjusted according to the bending requirements.

[0039] See also Figure 8 and Figure 9 As shown, fixed plates 28 are provided on both sides of the rectangular groove on the workbench 1, fixed limit plates 29 are provided on the fixed plates 28, a holder 210 is provided on one side of the fixed limit plate 29 on the fixed plate 28, and a movable limit plate 211 is provided in the holder 210.

[0040] When the bending seat 2 is adjusted, the movable limit plate 211 on the fixed plate 28 is moved out of the clamping seat 210. When the bending seat 2 moves to fit with the fixed limit plates 29 on both sides of the fixed plate 28, the bending grooves on both sides of the bending seat 2 correspond to the bending tool 5. When it is necessary to return to the initial position, the movable limit plate 211 is inserted into the clamping seat 210, and the bending seat 2 is driven to move until one side of the bending seat 2 fits with the movable limit plate 211, and the bending groove in the middle corresponds to the bending tool 5, thereby ensuring the accuracy of the bending.
