Description

Technical Field

[0001] The present invention relates to the technical field of bending machines, and in particular to a bending machine that is convenient for angle adjustment. Background Art

[0002] Press brakes are essential equipment for bending workpieces in the sheet metal industry. They can press steel plates into parts of various shapes according to process requirements and are widely used in a variety of industries, including metal processing, light industry, aviation, shipbuilding, metallurgy, home appliances, construction, electronics, and automobiles. In these fields, press brakes can achieve precise and efficient bending operations on metal sheets, allowing workpieces to achieve the desired shape and size.

[0003] For example, the Chinese patent publication number CN113787121A discloses a bending machine, comprising a bending mechanism for bending a product, the bending mechanism comprising a pad and a bending shaft, the pad being used to carry the product, the pad being movably arranged in a direction toward or away from the bending shaft to clamp or release the product, the bending machine also comprising a blanking mechanism, the blanking mechanism comprising: a first pusher, located between the pad and the bending shaft, the first pusher performing a linear reciprocating motion along the extension direction of the pad to push the product on the pad to the blanking mechanism. The assembly line, the unloading mechanism also includes: a frame, which is spaced apart from the bending mechanism; a turntable, which is rotatably arranged on the frame to drive the product to rotate at a first preset angle, wherein the first pusher performs a linear reciprocating motion between the turntable and the bending mechanism to push the product on the pad to the turntable; the flip assembly includes: a receiving plate, which is connected to the frame and is used to receive the product pushed by the second pusher; a movable plate, which is arranged opposite to the receiving plate and moves in a direction toward or away from the receiving plate to clamp or release the product.

[0004] For another example, Chinese patent publication number CN108838253B discloses “a bending machine, comprising: a first roller; a second roller, the second roller being spaced apart from the first roller; a support assembly, the support assembly being used to support a workpiece to be bent, the first roller and the second roller being both arranged above the support assembly; a positioning structure, the positioning structure being connected to the support assembly, the positioning structure being used to detect whether the workpiece has been conveyed to a preset position; wherein at least a portion of the support assembly is reversibly arranged so that the workpiece can be bent under the action of the support assembly and the first roller or under the action of the support assembly and the second roller”;

[0005] This type of patent mainly bends the product by driving the bending shaft to rotate. However, this bending method has certain technical defects:

[0006] First, during the bending process, the bending angle of the product is mainly determined by the displacement of the product driven by the pusher. When bending different products, different fixing parts need to be replaced to adapt to the push of different products, which has certain limitations.

[0007] Second, since the bending parts of the product generally have a certain toughness, when the product is bent by external force, stress concentration is likely to cause cracking, thereby affecting the bending quality of the product. Therefore, further improvement is needed. Summary of the Invention

The inner side of the mounting frame 3 is rotatably connected to a rotating ring 82. One end of the rotating ring 82 is provided with a bending member 83 for bending the product 7 to bend by cooperating with the rotation of the rotating ring 82. One end of the top of the base 1 is provided with a driving member 84 for driving the rotating ring 82 to rotate. One end of the mounting frame 3 is provided with a first fixing component 85 for clamping the product 7 to bend, and the top of the mounting frame 3 is provided with a second fixing component 86 for pressing the product 7 to bend.

[0037] By placing the product to be bent 7 on the movable carrier 6, and then controlling the movable cylinder 81 to make the movable carrier 6 move toward the inside of the mounting frame 3, the product to be bent 7 is transferred to the inside of the mounting frame 3, and then the first fixing component 85 and the second fixing component 86 are used to fix the product to be bent 7, and then the driving member 84 drives the rotating ring 82 to rotate, so that the bending member 83 bends the product to be bent 7.

The motor 841 causes the first gear 842 to rotate, which causes the second gear 843 to rotate synchronously, and the second gear 843 drives the rotating ring 82 to rotate synchronously, causing the mounting seat 831 to rotate, which causes the connecting seat 832 to drive the bending plate 833 to rotate circumferentially, so that the bending plate 833 applies pressure to the product to be bent 7, thereby bending the product to be bent 7.

[0042] The working principle and instructions for use of the present invention are as follows:

[0043] When in use, the article to be bent 7 is placed on the movable carrier 6, and then the movable cylinder 81 is controlled to move the movable carrier 6 toward the inside of the mounting frame 3, so that the article to be bent 7 is transferred to the inside of the mounting frame 3, and then the first clamping cylinder 851 is controlled to drive the movable seat 852 to move, so that the pressing plate 853 contacts the bending part of the article to be bent 7, so that the heating plate 8561 clamps the article to be bent 7, and the heating plate 8561 can heat the bending part of the article to be bent 7, which makes the bending part of the article to be bent 7. This can reduce the hardness of the bending part of the article to be bent 7 and increase its plasticity, thereby making it easier to achieve bending and reducing the problem of cracking caused by stress concentration during the bending process;

[0044] Then, by controlling the second clamping cylinder 862, the pressure seat 863 moves downward and presses the top of the workpiece 7 to be bent, so that the workpiece 7 to be bent remains fixed. Since the pressure seat 863 and the pressure plate 853 clamp the side and top surfaces of the workpiece 7 to be bent respectively, the pressure seat 863 and the pressure plate 853 can clamp different types of workpieces 7 to be bent, and there is no need to replace the fixing components when bending different workpieces 7 to be bent, which has strong versatility.

[0045] By starting the rotating motor 841, the first gear 842 rotates, which causes the second gear 843 to rotate synchronously, and the second gear 843 drives the rotating ring 82 to rotate synchronously. The rotation of the rotating ring 82 can cause the mounting seat 831 to rotate, which causes the connecting seat 832 to drive the bending plate 833 to rotate circumferentially, so that the bending plate 833 applies pressure to the product to be bent 7, thereby bending the product to be bent 7. By controlling the rotation angle of the rotating ring 82, the bending angle of the product to be bent 7 can be adjusted, which is easy to operate and can meet different bending requirements.
