The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0037] A flexible bending center is a machine capable of bending thin metal sheets, primarily used in the metal sheet processing industry. Flexible bending machines can bend metal sheets at various angles using simple molds, thus obtaining metal sheets with complex shapes. In operation, the sheet is typically pressed down by a pressure cutter mechanism, and then bent by a bending mechanism. When bending the four sides of the sheet, the pressing range of the pressure cutter needs to be adjusted for sheets of different lengths; this is known as blade alignment. While some bending blade alignment devices exist on the market, existing devices suffer from large structural volume, complex control, and difficulty in achieving modular loading and unloading.

[0038] Therefore, this utility model proposes a bending and assembling module with small structure and simple control, realizing modular loading and unloading, which only requires controlling the rotation direction and rotation angle of the transmission rod 210.

[0039] like Figure 1 and Figure 3 As shown, the bending and cutting module of this embodiment includes a base 100, a drive mechanism 200, and a cutting mechanism 300.

[0040] The base 100 is a shell structure, and the base 100 extends to the left and right.

[0041] like Figure 1 and Figure 2 As shown, the drive mechanism 200 of this embodiment is mounted on the base 100. The drive mechanism 200 includes a transmission rod 210 and a drive component 220. The transmission rod 210 extends to the left and right, and the left and right ends of the transmission rod 210 in this embodiment are rotatably connected to the base 100, which can improve the structural strength of the drive mechanism 200 and prevent the transmission rod 210 from tilting.

[0042] In this embodiment, the driving component 220 is used to drive the transmission rod 210 to rotate. In use, the driving component 220 can drive the transmission rod 210 to rotate forward or backward according to different needs.

[0043] In this embodiment, the transmission rod 210 is provided with a plurality of guide portions arranged sequentially along the axial direction. The guide portions are spirally arranged around the outer periphery of the transmission rod 210, and the pitch of the guide portions gradually changes along the circumference of the transmission rod 210.

[0044] like Figure 2 As shown, the pressing mechanism 300 includes multiple pressing blades, each of which includes multiple movable pressing blades. These movable pressing blades are arranged sequentially along the axial direction of the transmission rod 210. The movable pressing blades are slidably connected to the base 100 along the axial direction of the transmission rod 210. Each movable pressing blade has a linkage part 350 that slides with a guide part. In use, the driving component 220 drives the transmission rod 210 to rotate. The cooperation between the guide part, spirally arranged on the outer circumference of the transmission rod 210, and the gradually changing pitch of the guide part causes the multiple movable pressing blades to move axially along the transmission rod 210. Simultaneously, the distance between adjacent movable pressing blades is changed, thus adjusting the arrangement length of the multiple movable pressing blades. This invention adjusts the distance between each pair of adjacent movable pressing blades to improve the adaptability of the pressing blades.

[0045] When the transmission rod 210 rotates forward, the distance between the two movable pressure knives increases; when the transmission rod 210 rotates in reverse, the distance between the two movable pressure knives decreases.

[0046] To facilitate positioning and installation, such as Figure 2 As shown, the multiple pressure knives also include a fixed pressure knife 310 that is fixedly disposed relative to the base 100. The movable pressure knives are divided into multiple first movable pressure knives 320 and multiple second movable pressure knives 330 that are evenly distributed on both sides of the fixed pressure knife 310. It can be understood that the multiple first movable pressure knives 320 and multiple second movable pressure knives 330 on the left and right sides adjust the spacing with the fixed pressure knife 310 as the reference. During assembly, the fixed pressure knife 310 is used as the reference for installation and debugging, and the plate is also positioned by loading the plate with the fixed pressure knife 310 as the reference.

[0047] like Figure 2 As shown, the guide portion consists of multiple first guide portions 211 corresponding to the first movable pressure knife 320 and multiple second guide portions 212 corresponding to the second movable pressure knife 330. The spiral directions of the first guide portions 211 and the second guide portions 212 are opposite. It can be understood that when the transmission rod 210 rotates in one direction, the first guide portion 211 drives the first movable pressure knife 320 to move closer to the fixed pressure knife 310, while the second guide portion 212 drives the second movable pressure knife 330 to move closer to the fixed pressure knife 310. At this time, the moving directions of the first movable pressure knife 320 and the second movable pressure knife 330 are opposite. When the transmission rod 210 rotates in another direction, the first guide portion 211 drives the first movable pressure knife 320 away from the fixed pressure knife 310, while the second guide portion 212 drives the second movable pressure knife 330 away from the fixed pressure knife 310. At this time, the moving directions of the first movable pressure knife 320 and the second movable pressure knife 330 are opposite.

[0048] Furthermore, such as Figure 2 As shown, the pressing knife mechanism 300 of this embodiment also includes a plurality of mounting seats 340. The pressing knife is detachably mounted on the mounting seat 340. Specifically, the movable pressing knife is slidably mounted on the base 100 along the axial direction of the transmission rod 210 through the mounting seat 340, while the fixed pressing knife 310 is fixedly mounted on the base 100 through the mounting seat 340, and the linkage part 350 is fixed on the mounting seat 340.

[0049] like Figure 4 and Figure 5 As shown, the front side of the mounting base 340 is provided with a mounting boss 341, and the rear side of the pressure knife is provided with a mounting groove 360. The mounting groove 360 ​​and the mounting boss 341 are fitted together to limit the connection, which can improve the stability of the pressure knife installation and increase the load-bearing capacity.

[0050] At least one mounting screw hole 342 is provided on the front side of the mounting boss 341, and the pressure knife is provided with at least one mounting hole 370 that runs through the front and rear. The mounting hole 370 is provided with a mounting bolt 380 that is threadedly connected to the mounting screw hole 342. After the pressure knife is fitted onto the mounting boss 341, it is fixed by the mounting bolt 380. When subjected to force in the vertical direction, it is supported by the mounting groove 360 ​​and the mounting boss 341.

[0051] The base 100 of this utility model has at least two slide rails 110 arranged in the left-right direction on the front side. The at least two slide rails 110 are arranged in the direction perpendicular to the axial direction of the transmission rod 210 and are arranged vertically spaced. Two adjacent mounting seats 340 are slidably connected to different slide rails 110. In this embodiment, the mounting seat 340 is slidably engaged with the slide rail 110 through a slider 390. Two adjacent mounting seats 340 are slidably mounted on different slide rails 110 in a staggered manner. This can minimize the minimum distance between two adjacent mounting seats 340 and make the arrangement of the pressure knife more compact.

[0052] Since the fixed pressure knife 310 does not require adjustment, all mounting bases 340 in this embodiment are designed with the same structure for ease of production, processing, and assembly. The structures of the fixed pressure knife 310 and the movable pressure knife are also identical. Figure 2 As shown, in this embodiment, an annular limiting part 213 is provided on the outer periphery of the transmission rod 210, and the mounting base 340 on which the fixed pressing knife 310 is mounted is provided with a positioning part 343 that slides with the limiting part 213. At this time, the linkage part 350 is replaced by the positioning part 343. The limiting cooperation between the positioning part 343 and the limiting part 213 can realize the positioning of the fixed pressing knife 310.

[0053] In this embodiment, the guide part and the limiting part 213 are both groove structures, while the positioning part 343 and the linkage part 350 are slat structures, with the slat structures extending into the groove structure.

[0054] Furthermore, such as Figure 1 As shown, the drive mechanism 200 includes a first bevel gear 230 and a second bevel gear 240 that mesh with each other. The first bevel gear 230 is fixedly sleeved on the transmission rod 210, and the second bevel gear 240 is connected to the rotation drive end of the drive component 220. The drive component 220 is a servo motor. By rotating the first bevel gear 230 and the second bevel gear 240, the drive component 220 can be installed on the rear side of the base 100 to facilitate the installation of the bending die assembly on the bending machine.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0056] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
