Description

Technical Field

[0047] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a large arc double-machine linkage bending machine.

[0048] A large-arc double-machine linkage bending machine includes a double-machine linkage bending machine body 1 and a control panel 2. The control panel 2 is mounted on the double-machine linkage bending machine body 1. It also includes two sets of moving mechanisms, each set located within the double-machine linkage bending machine body 1, for moving parts; and two sets of fixing mechanisms, each set located on the moving mechanisms, for fixing the workpiece. The fixing mechanisms include: a mounting frame 3, mounted on the moving mechanisms, for mounting parts; two moving plates 4, each set within the mounting frame 3 and slidably connected to it; multiple electric push rods 5, each set on and fixedly connected to the moving plates 4; multiple springs 6, each set on and fixedly connected to the moving plates 4; multiple contact plates 7, each set on and fixedly connected to the springs 6; and multiple pressure sensors 8, each set within and fixedly connected to the contact plates 7.

[0049] refer to Figure 1 and Figure 4 In a preferred embodiment, the fixing mechanism further includes: two fixing columns 9, which are disposed within the mounting frame 3 and fixedly connected to the mounting frame 3; a first motor 10, which is disposed on the mounting frame 3 and fixedly connected to the mounting frame 3; and a first threaded rod 11, which is disposed at the output end of the first motor 10 and fixedly connected to the output end of the first motor 10.

[0050] In this configuration, the electric push rod 5 is used to adjust the position of the contact plate 7 and to support the contact plate 7. The electric push rod 5 and the contact plate 7 are connected by a ball joint, which allows the contact plate 7 to rotate more flexibly. During operation, the first motor 10 is started, and the second motor 12 drives the first threaded rod 11 to rotate. When the first threaded rod 11 rotates, it drives the moving plate 4 to move, so that the moving plate 4 drives the two side contact plates 7 to contact the workpiece and fix the workpiece. When there is curvature, the signal transmitted by the pressure sensor 8 causes the control panel 2 to control the electric push rod 5 to change the position of the contact plate 7, so that the contact plate 7 keeps in contact with the workpiece and prevents the workpiece from moving.

[0051] refer to Figure 2 and Figure 3 In a preferred embodiment, the moving mechanism includes: a drive unit disposed within the main body 1 of the dual-machine linkage bending machine for providing power; a moving unit disposed on the drive unit for moving the component; and a linkage unit disposed on the drive unit for linkage of the component.

[0052] refer to Figure 3In a preferred embodiment, the drive unit includes: a second motor 12, which is disposed inside the main body 1 of the dual-machine linkage bending machine and fixedly connected to the main body 1 of the dual-machine linkage bending machine; and a sealing cover 13, which is disposed on the main body 1 of the dual-machine linkage bending machine and fixedly connected to the main body 1 of the dual-machine linkage bending machine.

[0053] refer to Figure 3 In a preferred embodiment, the moving part includes: a second threaded rod 14, which is disposed inside the main body 1 of the dual-machine linkage bending machine and rotatably connected to the main body 1 of the dual-machine linkage bending machine; and a moving part 15, which is disposed on the second threaded rod 14 and threadedly connected to the second threaded rod 14.

[0054] refer to Figure 3 In a preferred embodiment, the linkage includes: a first sprocket 16, which is disposed on the output end of the second motor 12 and fixedly connected to the output end of the second motor 12; and a second sprocket 17, which is disposed on the second threaded rod 14 and fixedly connected to the second threaded rod 14.

[0055] In this configuration, both the first sprocket 16 and the second sprocket 17 are made of forged steel, which has high strength and good wear resistance. The first sprocket 16 and the second sprocket 17 are connected by a chain. The threads of the second threaded rods 14 on both sides are opposite in direction. During operation, the second motor 12 drives the first sprocket 16 to rotate, which in turn drives the second sprocket 17 to rotate via the chain. The second sprocket 17 then drives the second threaded rods 14 to rotate, causing the moving parts 15 on both sides to move the fixed mechanism. The movement allows the workpiece to be placed between the contact plates 7.

[0056] This device, by incorporating a moving mechanism, can adjust the position of the fixing mechanism according to the width of the workpiece when it is being fixed, allowing the device to clamp workpieces of different widths while keeping them centered. The fixing mechanism also enables the device to secure workpieces that require bending, and can flexibly adjust the clamping components promptly when the workpiece's curvature changes, facilitating the clamping of curved parts.

[0057] Working principle: When this device is working, the drive motors on both sides are started according to the width of the workpiece. The second motor 12 drives the first sprocket 16 to rotate, which in turn drives the second sprocket 17 to rotate via a chain. The second sprocket 17 then drives the second threaded rod 14 to rotate, causing the moving parts 15 on both sides to move the fixing mechanism. The movement is sufficient to place the workpiece between the contact plates 7. After the workpiece is placed on the contact plates 7, the first motor 10 is started, and the second motor 12 drives the first threaded rod 11 to rotate. When the first threaded rod 11 rotates, it drives the moving plate 4 to move, so that the moving plate 4 drives the contact plates 7 on both sides to contact the workpiece and fix the workpiece. When there is curvature, the signal transmitted by the pressure sensor 8 causes the control panel 2 to control the electric push rod 5 to change the position of the contact plate 7, so that the contact plate 7 keeps in contact with the workpiece and prevents the workpiece from moving.

[0058] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
