[0035] Reference Figure 1 to Figure 4 The bending blade mechanism of the utility model is implemented as follows:

[0036] like Figure 1 and Figure 2 As shown, the bending and splicing knife mechanism of the present invention comprises an upper knife seat 100 and a splicing knife assembly 200 .

[0037] The upper tool seat 100 is extended left and right, and a tool slot 110 is provided at the bottom of the upper tool seat 100. The number of the tool slots 110 can be determined according to actual conditions. In some embodiments, one tool slot 110 can be provided, while in this embodiment, two tool slots 110 are provided. The two tool slots 110 are arranged at intervals along the left and right directions, and the two tool slots 110 are symmetrically arranged with respect to the center line of the upper tool seat 100. When the plate is bent, the plate is loaded with reference to the center line of the upper tool seat 100.

[0038] The bottom surface of the upper tool holder 100 of this embodiment is a flat surface. During bending, the bottom surface of the upper tool holder 100 presses the plate against the lower tool holder of the bending machine, and the plate is bent by the bending mechanism at the rear side.

[0039] The number of the blade assemblies 200 corresponds to the number of the blade slots 110 , and the blade assemblies 200 are installed on the blade slots 110 one by one. The two blade assemblies 200 of this embodiment are also arranged symmetrically to facilitate adjustment.

[0040] like Figure 3 and Figure 4As shown, the jigsaw blade assembly 200 of this embodiment includes a plurality of jigsaw blade bodies 210 and a jigsaw blade driving structure 220, wherein the plurality of jigsaw blade bodies 210 are arranged side by side in the jigsaw blade slot 110 along the left-right direction, and the upper portion of the jigsaw blade body 210 is rotatably connected to the jigsaw blade slot 110, wherein the rotation axis of the jigsaw blade body 210 extends along the left-right direction, and the jigsaw blade driving structure 220 is used to drive the jigsaw blade body 210 to rotate independently around the rotation axis, that is, to drive the jigsaw blade body 210 to rotate along the front-back direction. It can be understood that the rotation trajectory of the jigsaw blade body 210 has two positions, which are divided into a working position and a non-working position, such as Figure 1 and Figure 2 As shown, when in the working position, the blade body 210 is located in the blade groove 110, and the blade body 210 is fitted sequentially from the inside to the outside of the center of the upper blade seat 100. When in the non-working position, the blade body 210 rotates from the inside to the outside of the blade groove 110 to a state of being disengaged from the blade groove 110.

[0041] When in use, when bending the four sides of the plate, all the blade bodies 210 can be put down and combined with the upper blade seat 100 to form an upper pressure blade body to achieve bending of the longer sides of the plate. When bending the horizontal sides between the bent two side edges of the plate, the number of blade bodies 210 combined with the upper blade seat 100 is adjusted according to the required bending length, and the other blade bodies 210 are driven to rotate by the blade driving structure 220, so that the blade bodies 210 of this part are flipped up and separated from the upper blade seat 100. This solution provides a blade groove 110 at the bottom of the upper blade seat 100, which can meet the needs of bending the four sides of plates of different sizes and longer plates. The structure is simple and can be achieved within the original size of the upper blade seat 100. The structure is compact.

[0042] like Figure 2 As shown, the lower part of the upper knife seat 100 is provided with a first pressing knife portion 120 extending backward, and the cross-section of the first pressing knife portion 120 is triangular, and the lower part of the knife body 210 is provided with a second pressing knife portion 211 extending backward, wherein the second pressing knife portion 211 is arranged to correspond to the shape and size of the first pressing knife portion 120 in the left and right directions.

[0043] The first pressing blade portion 120 and the second pressing blade portion 211 are arranged so that the plate can be bent to a bending angle within 90 degrees.

[0044] Further, a crossbeam 111 extending in the left-right direction is provided at the front side of the blade slot 110, and a limit slot 212 is provided at the front side of the lower part of the blade body 210, and the limit slot 212 is engaged with the crossbeam 111, such as Figure 4As shown, the jigsaw blade driving structure 220 of the present embodiment drives the jigsaw blade body 210 to rotate backward so that the second knife pressing part 211 is separated from the first knife pressing part 120. When the jigsaw blade body 210 rotates forward to a vertical state, that is, a working position, the limit slot 212 is engaged with the cross beam 111. It can be understood that when the jigsaw blade body 210 is rotated to a position where it is spliced ​​with the upper knife seat 100, the limit slot 212 is engaged with the cross beam 111 to achieve the fixation of the cross beam 111 in the jigsaw blade groove 110 in the up and down directions. In this way, when the plate is pressed, the structure of the jigsaw blade body 210 can be made more stable to avoid loosening in the up and down directions.

[0045] In addition, a chamfer 213 is provided on the front side of the bottom of the jigsaw blade body 210. When the jigsaw blade body 210 is adjusted, the jigsaw blade body 210 is rotated backward to a state of being disengaged from the first pressure blade part 120. The setting of the chamfer 213 can reduce the lower space required when the jigsaw blade body 210 rotates, and can prevent the jigsaw blade body 210 from touching the plate. Furthermore, when the jigsaw blade is adjusted, the upward stroke of the upper blade seat 100 can be reduced, thereby improving the bending efficiency.

[0046] like Figure 3 and Figure 4 As shown, the upper part of the jigsaw blade body 210 is provided with a rotating hole 214 which passes through in the left-right direction, and the left and right groove walls of the jigsaw blade groove 110 are both installed with bearing seats 112. A rotating shaft 113 extending left and right is connected between the two bearing seats 112. The rotating shaft 113 is rotatably fitted with multiple rotating holes 214. The jigsaw blade body 210 is rotatably installed by fitting the rotating holes 214 with the rotating shaft 113, thereby improving the stability of the connection of the jigsaw blade body 210.

[0047] like Figure 3 and 4 As shown, the upper portion of the jigsaw blade body 210 of the present embodiment is provided with an intersecting portion 215 eccentrically arranged with the rotating hole 214, and the jigsaw blade driving structure 220 includes a plurality of jigsaw blade driving members, and the driving ends of the plurality of jigsaw blade driving members are respectively connected to the plurality of intersecting portions 215. When the jigsaw blades are adjusted, the corresponding jigsaw blade driving members drive the corresponding jigsaw blade body 210 to rotate, and the jigsaw blade driving members drive the entire jigsaw blade body 210 to rotate by driving the intersecting portion 215.

[0048] The jigsaw blade assembly 200 of this embodiment includes a support frame 230 installed on the front side of the upper blade holder 100, and multiple jigsaw blade driving components are hinged on the support frame 230. The jigsaw blade driving components of this embodiment adopt telescopic cylinders 221, which can increase the speed of jigsaw blade adjustment.

[0049] In some embodiments, the blade drive member may adopt a linear drive structure such as an electric pole.

[0050] Furthermore, the thickness of the blade body 210 on each blade assembly 200 of the present embodiment is different along the left-right direction. By providing blade bodies 210 of different thicknesses, flexible blades can be used to bend plates of different specifications.

[0051] When in use, the plate is conveyed from front to back to the bottom of the upper knife seat 100. After the plate has completed the folding of the two opposite sides, the knife assemblies 200 on both sides are adjusted. According to the width of the two sides of the plate, the corresponding number of knife bodies 210 on both sides are rotated to the non-working position, and the other knife bodies 210 are sequentially fitted from the inside to the outside from the center of the upper knife seat 100. The plate is loaded with the center line of the upper knife seat 100 as the reference. At this time, the knife bodies 210 in the knife grooves 110 on both sides can be matched to plates of different specifications to complete the bending operation of the four sides of the plate.

[0052] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
