Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a simple bending tool and a bending machine. Background Art

[0002] A bending machine is a device used to process metal sheets or other materials, which can bend flat materials into various shapes and is commonly used in the fields of manufacturing automotive parts, aerospace components, building structures, etc. Existing multi-axis bending machines usually have an X-axis, a Y-axis and a Z-axis. Among them, the X-axis and the Y-axis control the movement of the tool, and the Z-axis controls the movement of the upper die table. The multi-axis bending machine has the advantages of high efficiency and strong adaptability. However, the tools of existing multi-axis bending machines are usually C-shaped. For example, the Chinese utility model patent with the publication number CN209716125U discloses a sheet metal bending device, including a bending tool. The bending tool includes a C-shaped frame, an upper bending tool and a lower bending tool respectively connected to the upper end and the lower end of the C-shaped frame. This bending tool is connected through the C-shaped frame, and the sheet metal is processed between the upper bending tool and the lower bending tool. In order to meet the larger feeding distance and bending length as much as possible, the length of the C-shaped frame is usually long, and a large distance needs to be maintained between the upper bending tool and the lower bending tool. In this way, the sheet metal at the tool will cause the overall volume of the bending tool to be large. When performing forward and reverse switching operations, a large stroke needs to be moved, and the overall processing efficiency is low. Moreover, this bending tool is assembled from multiple parts and components, and the overall strength is low. Summary of the Utility Model

[0020] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present utility model are only based on the drawings of the present utility model, and they do not specifically limit the present utility model.

[0021] Referring to Figure 1 , an embodiment of the present utility model discloses a simple bending tool 10, which is arranged on the side of the bending opening 7. The bending opening 7 is the position when the sheet material is bent. The simple bending tool 10 includes a tool holder 2 and a tool head 1. The tool holder 2 extends towards the side where the bending opening 7 is located. The tool is close to the bending opening 7. One end of the tool holder 2 is provided with a plug-in slot 21. A limit buckle 111 is arranged on one side of the tool head 1. The limit buckle 111 can be inserted into the plug-in slot 21. The tool head 1 has multiple specifications, and the specifications of the limit buckles 111 of the tool heads 1 with multiple specifications are the same, so they can all be inserted into the plug-in slot 21, and the interchangeability is high. Wherein the tool head 1 includes an integrally arranged connecting portion 11, an upper bending portion 12 and a lower bending portion 13. The limit buckle 111 is arranged on the connecting portion 11. The upper bending portion 12 is arranged on the upper part of the connecting portion 11 and protrudes upwards. The lower bending portion 13 is arranged on the lower part of the connecting portion 11 and protrudes downwards. The upper and lower parts of the tool head 1 respectively protrude above and below the tool holder 2. The tool head 1 can form a "T" shape with the tool holder 2, which is different from the "C" shape structure of the existing bending tool. The upper end of the upper bending portion 12 is provided with an upper folding plate 121, and the lower end of the lower bending portion 13 is provided with a lower folding plate 131. The upper folding plate 121 can be used for forward bending, that is, bending the sheet material upwards, and the lower folding plate 131 can be used for reverse bending, that is, bending the sheet material downwards. For the traditional "C" type bending tool, the upper tool and the lower tool are at a relatively long distance. Because the sheet material is located between the upper tool and the lower tool, when bending upwards or downwards, it is necessary to avoid interference between the bent sheet material and the upper tool or the lower tool. Therefore, it is necessary to extend the distance between the upper tool and the lower tool to obtain a longer bending length. However, in the embodiment of the present utility model, since the tool head 1 and the tool holder 2 form a "T" shape structure, the sheet material is no longer located between the upper folding plate 121 and the lower folding plate 131, and the distance between the upper folding plate 121 and the lower folding plate 131 is no longer limited by the bending length. Therefore, the distance between the upper folding plate 121 and the lower folding plate 131 can be reduced.

[0022] The beneficial effects of the embodiment of the present utility model are as follows:

[0023] In an embodiment of the present utility model, the simple folding tool 10 is provided with a tool holder 2 and a tool head 1. The limit buckle 111 of the tool head 1 is connected to a folding machine by using the insertion slot 21 of the tool holder 2. Wherein, the tool head 1 includes a connecting portion 11, an upper folding portion 12 and a lower folding portion 13. The connecting portion 11 is connected between the upper folding portion 12 and the lower folding portion 13. An upper folding plate 121 is provided at the upper end of the upper folding portion 12, and a lower folding plate 131 is provided at the lower end of the lower folding portion 13. The upper folding plate 121 can be folded forward, and the lower folding plate 131 can be folded backward. Compared with the tool connected by a traditional C-shaped frame, the simple folding tool 10 of the present utility model has a smaller volume, and there is no need to extend the distance between the upper folding plate 121 and the lower folding plate 131 to obtain a larger feeding distance and folding distance. In this way, the distance between the upper folding plate 121 and the lower folding plate 131 can be set shorter. While reducing the overall volume, the stroke during the forward and reverse switching is also shortened. Moreover, the connecting portion 11, the upper folding portion 12 and the lower folding portion 13 are integrally arranged, and the overall strength is higher.

[0024] Specifically, referring to Figure 2 , in order to enhance the connection strength, the upper folding portion 12 further includes an upper cantilever 122 and a front folding plate 123. The upper cantilever 122 is connected to the upper part of the connecting portion 11. The front folding plate 123 is obliquely connected to the upper cantilever 122. The upper folding plate 121 is obliquely connected to the front folding plate 123. The front folding plate 123 and the upper cantilever 122 can strengthen the connection strength between the upper folding portion 12 and the connecting portion 11, improve the shear strength between the upper cantilever 122 and the upper folding plate 121, and make the upper folding plate 121 not easily break. In addition, the upper folding portion 12 further includes a support plate 124. The lower part of the support plate 124 is connected to the upper part of the connecting portion 11. The upper part of the support plate 124 is connected to the lower part of the upper cantilever 122. The support plate 124 is vertically arranged. The upper cantilever 122 is obliquely upwardly arranged towards the side close to the tool holder 2. The support plate 124 is connected between the connecting portion 11 and the upper cantilever 122, and can improve the connection strength between the upper cantilever 122 and the connecting portion 11.

[0025] Further, the front folding plate 123 extends upward and obliquely from the upper part of the upper cantilever 122 toward the side away from the tool holder 2, and the upper folding plate 121 is arranged upward and obliquely from the upper part of the front folding plate 123 toward the side away from the tool holder 2. The upper folding plate 121, the front folding plate 123, and the upper cantilever 122 form a "C"-shaped structure. The upper folding plate 121 is arranged upward and obliquely. By reasonably setting the inclination angle of the upper folding plate 121, the acting force direction of the upper folding plate 121 during upward bending can be made the same as the resultant direction during the linkage of each moving axis of the bending machine, thereby improving the bending efficiency and reducing the shearing of the upper folding plate 121, and prolonging the service life. In the embodiment of the present utility model, the included angle between the upper folding plate 121 and the front folding plate 123 is greater than 90°, and the upper folding plate 121 is arranged upward and obliquely, and its inclination direction can be the same as the resultant direction during the linkage of each moving axis of the bending machine.

[0026] In addition, in order to avoid interference between the upper cantilever 122 and the sheet material during bending, a first transition inclined surface 1221 and a second transition inclined surface 1222 are provided on the side of the upper cantilever 122 away from the tool holder 2. One side of the first transition inclined surface 1221 is connected to the support plate 124, the other side of the first transition inclined surface 1221 is inclinedly connected to one side of the second transition inclined surface 1222, and the other side of the second transition inclined surface 1222 is connected to the front folding plate 123. The included angle between the first transition inclined surface 1221 and the horizontal plane is smaller than the included angle between the second transition inclined surface 1222 and the horizontal plane. Since the upper folding plate 121 extends toward the bending opening 7, during forward bending, the upper cantilever 122 will gradually approach the bent edge of the sheet material. By reasonably setting the included angle between the first transition inclined surface 1221 and the second transition inclined surface 1222, the second transition inclined surface 1222 can be made to avoid the bent edge of the sheet material and not affect the bending.

[0027] In the lower bending part 13, the lower bending part 13 further includes a lower cantilever 132. The lower cantilever 132 is connected to the lower part of the connecting part 11, and the lower folding plate 131 is connected to the lower part of the lower cantilever 132. The lower folding plate 131 extends downward and obliquely toward the side away from the tool holder 2. The extending direction of the lower folding plate 131 is substantially the same as that of the upper folding plate 121, both toward the side where the bending opening 7 is located, but the upper folding plate 121 is arranged upward and obliquely, and the lower folding plate 131 is arranged downward and obliquely. By reasonably setting the inclination angle between the lower folding plate 131 and the lower cantilever 132, the acting force direction of the lower folding plate 131 during downward bending can be made the same as the resultant direction during the linkage of each moving axis of the bending machine, thereby improving the bending efficiency and reducing the shearing of the lower folding plate 131, and prolonging the service life.

[0028] In addition, the lower cantilever 132 has a front side surface 1321 and a rear side surface 1322 on both sides, the front side surface 1321 is vertically arranged, a transition groove 1323 is arranged between the front side surface 1321 and the side of the connecting portion 11, and the rear side surface 1322 is obliquely connected between the connecting portion 11 and the lower folding plate 131. When bending downward, the lower cantilever 132 will gradually approach the bending edge of the sheet material, and the transition groove 1323 is used to generate an avoidance space to prevent the lower cantilever 132 from interfering with the sheet material.

[0029] The horizontal distance from the upper folding plate 121 to the tool holder 2 is smaller than the horizontal distance from the lower folding plate 131 to the tool holder 2, that is, the lower folding plate 131 is closer to the bending opening 7 than the upper folding plate 121. This arrangement can further ensure that the force exerted on the sheet material by the upper folding plate 121 and the lower folding plate 131 during bending is in the same direction as the combined direction when the moving axes in the bending machine are linked, thereby improving the bending efficiency and extending the service life.

[0030] See also Figure 3The utility model embodiment also discloses a bending machine, including the simple bending tool 10 as described above, and also includes a frame 3, a horizontal moving mechanism 4, a vertical moving mechanism 5 and an upper die moving mechanism 6 arranged on the frame 3, the horizontal moving mechanism 4 can drive the vertical moving mechanism 5 and the simple bending tool 10 to move in the X-axis, the vertical moving mechanism 5 can drive the simple bending tool 10 to move in the Y-axis, a lower die table 31 is provided on the frame 3, the lower die table 31 is located at the front side of the simple bending tool 10, the sheet material is placed on the lower die table 31 for bending, the horizontal moving mechanism 4 includes a horizontal driving member 41 and a horizontal moving seat 42 connected to the horizontal moving frame, the horizontal driving member 41 is preferably a rotating motor, which can The horizontal movable seat 42 can be driven to move in the X-axis by a screw rod. The vertical movable mechanism 5 includes a slide 51 fixed on the horizontal movable seat 42, a vertical driving member 52 arranged on the slide 51, and a vertical movable seat 53 connected to the vertical driving member 52. The vertical driving member 52 is preferably a rotary motor, which can drive the vertical movable seat 53 to move in the Y-axis by a screw rod. One end of the tool holder 2 is fixed on the vertical movable seat 53, and the other end of the tool holder 2 is connected to the tool head 1. The upper mold moving mechanism 6 includes an upper mold driving member 61 and an upper mold table 62 connected to the upper mold driving member 61. The upper mold table 62 is located above the lower mold table 31, and the bending mouth 7 is formed between the upper mold table 62 and the lower mold table 31. The sheet material enters the bending opening 7, the upper die driving member 61 drives the upper die table 62 to press the sheet material, and the horizontal moving mechanism 4 and the vertical moving mechanism 5 jointly drive the simple bending tool 10 to move to bend the sheet material. Compared with the tool connected by the traditional C-frame, the distance between the upper folding plate 121 and the lower folding plate 131 of the bending machine of the utility model embodiment is shorter, so the overall volume is smaller, and an efficient bending effect can be obtained, and the tool head 1 of the simple bending tool 10 is integrated, has higher strength, and thus has a longer service life.
