[0028] 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.
[0029] 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.
[0030] Because metal sheets have a certain degree of resilience, when bending the sheet to a set angle, it needs to be bent to a position greater than the set angle. After that, the sheet will rebound to the set angle. In the process of bending the four sides of the sheet to form a drawer-shaped structure, when the opposite two sides of the sheet are bent and then the middle side is bent, the bent edge needs to be bent to a position greater than 90 degrees. At this time, the bent edges on both sides will interfere with the movement of the bending knife. Currently, a shorter bending knife is generally used to avoid this interference. However, for longer edges, there is uneven stress at both ends and the middle of the edge. The ends of the edge are prone to bending and deformation, which will affect the bending and forming effect. Therefore, this utility model proposes a bending knife for flexible bending center to solve the above problems and improve the bending and forming effect.
[0031] like Figures 1 to 3 As shown, the folding knife in this embodiment includes a folding knife body 100, which extends horizontally in the length direction.
[0032] In this embodiment, the folding blade body 100 has a bending side 110 and a fixing side 120 arranged opposite to each other along the width direction. The bending side 110 and the fixing side 120 extend along the length direction, wherein the fixing side 120 is used for fixed connection, and the bending side 110 is used for contact with the plate. The bending side 110 has a plurality of clearance grooves 111 arranged at intervals along the length direction of the folding blade body 100. The clearance grooves 111 extend along the thickness direction of the folding blade body 100 and extend along the width direction of the folding blade body 100. The clearance grooves 111 have slots 112 facing the outside of the bending side 110.
[0033] In use, the folding blade body 100 is connected to an external bending drive mechanism via a fixed side 120. Driven by the external bending drive mechanism, the folding blade body 100 abuts against the board via the bending side 110 to achieve bending of the board. During the process of bending the four sides of the board to form a drawer-shaped structure, when the opposite two sides of the board are bent and the middle side is bent, the bending side 110 avoids the bent edges on both sides of the board via the avoidance groove 111, so that the folding blade does not collide with the bent edges on both sides of the board. It also ensures the direct contact range between the folding blade body 100 and the board, improving the uniformity of force during board bending. In addition, multiple avoidance grooves 111 are arranged at intervals along the length of the folding blade body 100 to accommodate boards of different sizes.
[0034] In order to allow the bent edges on both sides of the sheet to smoothly enter the clearance groove 111, the groove 112 in this embodiment is set to gradually increase in size from the fixed side 120 to the bending side 110.
[0035] In this embodiment, a groove strip 113 is provided between two adjacent clearance grooves 111. The end of the groove strip 113 near the bending side 110 is provided with a rounded corner structure 114 so that the groove opening 112 gradually increases. The rounded corner structure 114 can guide the folded edge. When the folded edge is just located at the position of the groove strip 113, it can be guided into the clearance groove 111.
[0036] In this embodiment, the width of the clearance groove 111 along the length of the folding blade body 100 is twice the thickness of the plate strip 113 along the length of the folding blade body 100. This ensures that the bending side 110 has good structural strength while making the clearance range of the clearance groove 111 larger.
[0037] Regarding the fixed installation method of the folding blade body 100, the fixed side 120 of this embodiment is provided with a plurality of fixing screw holes 121 arranged at intervals along the length direction of the folding blade body 100, wherein the fixing screw holes 121 extend along the width direction and the folding blade body 100 is fixed by bolts.
[0038] Furthermore, the folding blade body 100 is provided with a fixing through hole 122 located between the bending side 110 and the fixing side 120. The fixing through hole 122 extends through the thickness direction of the folding blade body 100. The setting of the fixing through hole 122 can further improve the firmness of the folding blade body 100.
[0039] The fixed through hole 122 has a stepped hole structure, which can achieve the effect of concealing the installation of the nut.
[0040] Furthermore, the bending side 110 of this embodiment includes a middle part 115 and two side parts 116. The two side parts 116 are symmetrically arranged on both sides of the middle part 115 along the length direction of the bending blade body 100. Each of the two side parts 116 is provided with a plurality of clearance grooves 111. The middle part 115 is a flat structure flush with the groove opening 112. It can be understood that the clearance grooves 111 are arranged on the side parts 116, while the middle position of the bending side 110 is a flat structure. This can reduce the processing of the clearance grooves 111. At the same time, the clearance grooves 111 on the two side parts 116 are symmetrically arranged, which also facilitates positioning control.
[0041] In some embodiments, the folding blade body 100 includes a plurality of combined blade bodies 130, which are arranged sequentially along the length of the folding blade body 100. The middle part 115 is located on one part of the combined blade bodies 130, and the side parts 116 are located on another part of the combined blade bodies 130. It can be understood that the folding blade body 100 in this embodiment is a composite component. The combined blade bodies 130 with the clearance groove 111 can be processed individually and then assembled. Specifically, this embodiment has three combined blade bodies 130, with the middle part 115 located on the middle combined blade body 130, and the two side parts 116 respectively located on the two side combined blade bodies 130.
[0042] In addition, this utility model also proposes a flexible bending center, which includes the aforementioned bending blade.
