Description

Technical Field

[0001] The utility model relates to the technical field of bending dies, in particular to a bending center die with an avoidance function. Background Art

[0002] When using a bending center to bend a sheet, if there are raised or irregular structures on the bending part, they will interfere with the bending tool, requiring the bending tool to have a avoidance function. For example, in the prior art, patent document No. CN220781870U discloses a bending tool with left and right avoidance functions, comprising: a mounting base, a first blade body, and a second blade body; the mounting base is used to be detachably connected to the device to be installed; the first blade body is located at an end of the mounting base away from the device to be installed; the second blade body is slidably located at an end of the mounting base away from the device to be installed, and a cylinder and a transmission rod are provided on one side of the second blade body; the second blade body is threadedly connected to the transmission rod, one end of the transmission rod is connected to the output end of the cylinder, and the other end of the transmission rod is transmission-connected to the first blade body; the cylinder is used to drive the transmission rod to drive the second blade body to move away from or toward the first blade body. The utility model has a avoidance function and can avoid raised or irregular structures on the bending part.

[0003] In actual use, the plate is bent into a rectangular four-sided bending box. When two adjacent sides already have bent edges, the bending tool will interfere with the bent edges. During the process of feeding and retracting, the bending tool needs to avoid the bending edges. However, most existing molds are driven by cylinders to avoid the bending edges, which has the problem of poor action coordination, causing inconvenience in use and needs further improvement.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a bending center mold with an avoidance function, comprising a mold body, a driving plate slidably mounted on the side of the mold body, a mounting notch provided between the mold body and the driving plate, a transmission block movably provided in the mounting notch, and an avoidance block fixedly mounted on the lower side of the transmission block;

[0006] A first guide groove is provided inside the mold body, a second guide groove is provided on the side of the driving plate, a first mounting hole and a second mounting hole are provided on the side of the transmission block, a first pin shaft is rotatably inserted in the first mounting hole, and the end of the first pin shaft extends into the first guide groove, a second pin shaft is rotatably inserted in the second mounting hole, and both ends of the second pin shaft extend into the first guide groove and the second guide groove respectively, and the action of the avoidance block is controlled by the driving plate linkage to achieve the effect of avoiding interference.

[0007] In some embodiments, an assembly pressure plate is fixedly installed on the side of the mold body by bolts, a limiting block is fixedly installed on the top of the assembly pressure plate, a limiting groove is provided on the side of the mold body, the limiting block is slidably inserted into the limiting groove, a vertical slide groove is provided on the inner side wall of the assembly pressure plate, and the driving plate is slidably installed in the vertical slide groove. When the bottom end of the driving plate is pressed against the upper surface of the bent plate, the driving plate can slide upward to lift the mold body, and the driving plate can extend downward, and the up and down sliding of the driving plate is used to drive the avoidance block to move.

[0008] In some embodiments, the first guide groove includes a vertical section groove and an inclined section groove, the inclined section groove has the same inclination angle as the second guide groove, and the ends of the first pin shaft and the second pin shaft are rotatably installed with guide rollers, and the two guide rollers roll along the inner cavity of the first guide groove, so that the first pin shaft and the second pin shaft can slide along the first guide groove, thereby driving the avoidance block to flip.

[0009] In some embodiments, a positioning groove is provided on the lower surface of the mold body, and the upper end of the avoidance block is matched with the inner wall of the positioning groove. When the upper end of the avoidance block is tightly attached to the inner wall of the positioning groove, the lower surfaces of the avoidance block and the driving plate are in the same plane. When the mold is pressed down, the lower surfaces of the avoidance block 4 and the driving plate 2 are both pressed against the surface of the bent plate.

[0010] In some embodiments, a first bending edge and a second bending edge are provided on the lower surface of the avoidance block, and the angle between the first bending edge and the second bending edge is a right angle.

[0011] Beneficial effects

[0012] The utility model provides a bending center mold with a avoidance function, which has the following beneficial effects:

[0013] The bending center mold with avoidance function realizes the function of avoiding the bending edge by arranging a transmission block between the mold body and the avoidance block. The transmission block moves along the direction of the first guide groove with the first pin and the second pin, so that the avoidance block moves in the direction consistent with the path of the first guide groove.

[0014] By arranging a driving plate that can slide up and down on the side of the mold body, when the mold is pressed down to feed, the driving plate is pressed upward, and the avoidance block is driven to rotate to the horizontal and pressed against the upper surface of the bent plate through the transmission of the first pin shaft and the second pin shaft. When the mold is lifted to retract, the driving plate extends downward under the action of gravity, driving the avoidance block to rotate to an inclined state, thereby realizing the linkage control of the avoidance block through the driving plate to achieve the effect of avoiding interference. The design structure is simple and easy to use. There is no need to add a driving component to drive the avoidance block to move, which solves the problem of poor coordination of the avoidance action of the existing mold.

[0025] A positioning groove 15 is provided on the lower surface of the mold body 1. The upper end of the avoidance block 4 is aligned with the inner wall of the positioning groove 15. When the upper end of the avoidance block 4 is in close contact with the inner wall of the positioning groove 15, the lower surfaces of the avoidance block 4 and the drive plate 2 are in the same plane. When the mold is pressed down, the lower surfaces of the avoidance block 4 and the drive plate 2 are pressed against the surface of the bent plate 18. Figure 4 As shown in Figure b, when the bottom end of the driving plate 2 is pressed against the upper surface of the bent plate 18, Figure 4 As shown in Figure a, the force F pushes the driving plate 2 to slide upward, lifting the mold body 1, as shown in Figure Figure 4 As shown in Figure c, gravity G causes the driving plate 2 to extend downward, and the up and down sliding of the driving plate 2 drives the avoidance block 4 to move.
