Description

Technical Field

[0001] This utility model belongs to the field of bending equipment technology, and in particular relates to a continuous bending forming machine for metal plates. Background Technology

[0002] Depending on the specific application requirements, metal sheets may need to be bent at certain angles. In the industry, bending machines are commonly used to bend metal sheets.

[0003] Currently used metal sheet bending machines require workers to place the workpiece between the upper and lower dies during processing. Then, the upper die is lowered to cooperate with the lower die to bend the workpiece. After bending, workers need to remove the workpiece from between the upper and lower dies. If the upper die is accidentally driven, workers are prone to injury, posing a safety hazard. In addition, the processing efficiency is not high. Therefore, existing metal sheet bending machines need to be improved. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a continuous bending forming machine for metal sheets. This bending machine eliminates the need for workers to frequently approach the upper and lower dies, reducing safety hazards. Furthermore, the bent workpieces can be automatically unloaded, enabling continuous processing and improving production efficiency.

[0005] In view of this, the present invention provides a continuous bending forming machine for metal sheets, comprising:

[0006] The frame has a lower die and an upper die that can move closer to or further away from the lower die. The upper die and the lower die work together to bend the workpiece.

[0007] The positioning plate is set on one side of the lower mold in the first direction. The positioning plate can position one end of the workpiece and can move away from the lower mold in a direction perpendicular to the first direction.

[0008] The clamping component is mounted on the frame and can clamp and fix the workpiece on the lower mold.

[0009] The pusher is located on the side of the lower mold away from the positioning plate. The pusher can push the workpiece toward the positioning plate.

[0010] In this technical solution, the worker places the workpiece to be bent on the side of the lower mold away from the positioning plate. The pusher pushes the workpiece in the first direction so that one end of the workpiece is in contact with the positioning plate. At this time, the workpiece reaches the processing position. Then, the clamping component fixes the workpiece on the lower mold. Then, the upper mold approaches the lower mold and cooperates with the lower mold to bend the workpiece. After bending, the upper mold moves away from the lower mold, the positioning plate moves away from the lower mold, and the clamping component releases the workpiece. Then, the pusher continues to push the workpiece in the first direction so that the workpiece is pushed off the lower mold, completing the loading, processing, and unloading process of one workpiece.

[0011] In the above technical solution, the upper mold is located above the lower mold, and a bending cylinder is provided on the frame, which can drive the upper mold to move in the vertical direction.

[0012] In the above technical solution, a retraction cylinder is further provided on the frame, which can drive the positioning plate to move in the vertical direction.

[0013] In the above technical solution, the clamping component further includes:

[0014] Clamping block, the clamping block is located above the lower mold;

[0015] The clamping cylinder is mounted on the frame and can drive the clamping block to move vertically.

[0016] In the above technical solution, the pusher component further includes:

[0017] The swing frame has a first end that is rotatably mounted on the machine frame, and the second end of the swing frame can push the workpiece on the lower mold in the first direction along the motion trajectory.

[0018] The driving component can drive the first end of the swing frame to rotate in the forward and reverse directions.

[0019] In the above technical solution, the swing frame is U-shaped, the movement trajectory of the swing frame coincides with the position of the clamping member, and the swing frame can pass through the clamping member during the swinging process.

[0020] In the above technical solution, a further step is to provide a conveying mechanism on the side of the lower mold away from the positioning plate, which can sequentially convey multiple workpieces to the lower mold.

[0021] In the above technical solution, the transmission mechanism further includes:

[0022] The conveyor belt is mounted on the frame and is located on the side of the lower mold away from the positioning plate.

[0023] Limiting plates are installed on both sides of the conveyor belt in the conveying direction. Both limiting plates are mounted on the frame, and the distance between the two limiting plates is adapted to the width of the workpiece.

[0024] The beneficial effects of this utility model are:

[0025] 1. By cooperating with positioning plates, clamping parts, and pushing parts, automatic feeding and unloading are achieved. This eliminates the need for workers to place the workpiece between the upper and lower molds during feeding, and also eliminates the need for workers to remove the bent workpiece from between the upper and lower molds after processing. This reduces safety hazards during operation, reduces labor intensity, and improves production efficiency.

[0026] 2. By designing the pusher as a combination of a swing frame and a drive component, and aligning the movement trajectory of the swing frame with that of the clamping component, the swing frame can pass through the clamping component during the swing process. This allows the pusher and clamping components to be more compactly distributed, thereby reducing the overall size of the equipment.

[0027] 3. By setting a conveying mechanism on the side of the lower mold away from the positioning plate, multiple workpieces can be sequentially conveyed to the lower mold, thus enabling continuous processing and further improving production efficiency. Attached Figure Description

The frame 1 is provided with a bending cylinder 7, which can drive the upper mold 3 to move in the vertical direction Y.

[0043] Please see Figure 2 or Figure 3 The positioning plate 4 is set on one side of the lower mold 2 located in the first direction X. The positioning plate 4 can position one end of the workpiece 100. The positioning plate 4 can move away from the lower mold 2 perpendicular to the first direction X.

[0045] The pusher 6 is located on the side of the lower mold 2 away from the positioning plate 4. The pusher 6 can push the workpiece 100 toward the positioning plate 4.

[0046] When the continuous bending forming machine of this embodiment is in operation, please refer to... Figure 4 The worker places the workpiece 100, which needs to be bent, on the side of the lower mold 2 away from the positioning plate 4. At this time, the pusher 6 is located on the side of the workpiece 100 away from the positioning plate 4, and the upper surface of the positioning plate 4 is higher than the upper surface of the lower mold 2; then please refer to Figure 5 The pusher 6 pushes the workpiece 100 in the first direction X so that one end of the workpiece 100 is in contact with the positioning plate 4. At this time, the workpiece 100 reaches the processing position, and the clamping member 5 fixes the end of the workpiece 100 that does not need to be bent on the lower mold 2; then please refer to Figure 6 Driven by the bending cylinder 7, the upper die 3 approaches the lower die 2 and cooperates with the lower die 2 to bend the end of the workpiece 100 that needs to be bent; finally, please refer to Figure 7 The bending cylinder 7 drives the upper mold 3 away from the lower mold 2, and the retraction cylinder 8 drives the positioning plate 4 away from the lower mold 2. At the same time, the clamping part 5 releases the workpiece 100, and then the pusher 6 continues to push the workpiece 100 in the first direction X, so that the workpiece 100 is pushed off the lower mold 2. After the processed workpiece 100 is pushed away from the lower mold 2, the retraction cylinder 8 drives the positioning plate 4 to reset, preparing for the positioning of the next workpiece 100.

[0047] In this embodiment, a collection container can be placed at the unloading position of the workpiece 100 to collect the processed workpiece 100.

[0048] Example 2

[0049] Based on Embodiment 1, this embodiment also discloses a structure of the clamping member 5;

[0051] Please see Figure 3 The clamping block 501 is located above the lower mold 2;

[0052] The clamping cylinder 502 is mounted on the frame 1 and located above the clamping block 501. The clamping cylinder 502 can drive the clamping block 501 to move in the vertical direction Y.

[0053] Please see Figure 4 Before the pusher 6 pushes the workpiece 100 to the processing position, the distance between the clamping block 501 and the lower mold 2 is greater than the thickness of the workpiece 100, allowing the workpiece 100 to pass through between the clamping block 501 and the lower mold 2; please refer to Figure 5 When the workpiece 100 reaches the processing position, the clamping cylinder 502 drives the clamping block 501 to approach the lower mold 2, and finally the clamping block 501 cooperates with the lower mold 2 to fix the workpiece 100.

[0058] The driving component 602 can drive the first end of the swing frame 601 to rotate in the forward and reverse directions. The driving component 602 can be a motor, preferably a motor that can precisely control the driving angle, such as a servo motor.

[0059] Please see Figure 4 In the initial position, the second end of the swing frame 601 is located above the workpiece 100 on the lower mold 2, and on the side of the workpiece 100 away from the positioning plate 4. Please refer to [link / reference]. Figure 5The driving component 602 drives the second end of the swing frame 601 to swing counterclockwise to push the workpiece 100 toward the first direction X. When one end of the workpiece 100 contacts the positioning plate 4, the swing frame 601 stops swinging. After the workpiece 100 is processed and the clamping component 5 releases the workpiece 100, the driving component 602 drives the second end of the swing frame 601 to continue to swing counterclockwise to push the workpiece 100 away from the lower mold 2. Finally, the driving component 602 drives the second end of the swing frame 601 to swing clockwise to reset, preparing for the next workpiece 100 to be pushed.

[0060] Example 4
