[0016] A new type of bending mechanism of bending machine, such as Figure 1 , 2, 3, 4, and 5, comprising a workbench 1, on which a lower mold 2 is fixedly provided, an upper mold tool 3 is installed on the workbench 1 through a driving device, the upper mold tool 3 can cooperate with the lower mold 2, and the plate 100 is bent by the cooperation of the upper mold tool 3 and the lower mold 2, and a plurality of supporting legs 4 are fixedly installed on the lower side of the workbench 1, characterized in that: a lower groove 6 and an upper groove 5 are sequentially provided on the side opposite to the lower mold 2 and the upper mold tool 3, an upper plate 7 and a lower plate 8 are sequentially movably installed in the upper groove 5 and the lower groove 6, and when the upper plate 7 and the lower plate 8 are located in the corresponding upper groove 5 and the lower groove 6, the upper plate 7 and the lower plate 8 are The outer periphery is respectively in contact with the side wall of the corresponding upper groove 5 and lower groove 6, and a through hole 9 is respectively provided on the side wall of the upper groove 5 and lower groove 6. The two through holes 9 are coaxially arranged, and a spring rod 10 is respectively installed in the through holes 9 for sliding cooperation. When the two spring rods 10 are in a relaxed state, the movable ends of the spring rods 10 are located in the fixed ends, and the inner periphery of the through holes 9 is respectively in contact with the outer periphery of the corresponding spring rods 10 for sliding cooperation. The movable ends of the spring rods 10 are respectively fixedly connected to the corresponding upper plate 7 or lower plate 8, and the fixed ends of the spring rods 10 are fixedly connected through the same connecting rod 11, and the connecting rod 11 can be in contact with the upper die cutter 3. The utility model has a simple structure and an ingenious design. In the process of the upper die cutter 3 moving upward, the bent sheet 100 is successively separated from the lower die 2 and the upper die cutter 3, which is convenient for loading and unloading of the sheet 100, improves the operational safety when loading and unloading the sheet 100, can meet actual needs, and is suitable for promotion.When using the utility model, first place the plate 100 between the lower mold 2 and the upper mold tool 3, then use the driving device to drive the upper mold tool 3 to move downward, the upper mold tool 3 and the lower mold 2 cooperate to bend the plate 100, at this time, the spring rod 10 in the upper mold tool 3 is in a pulled state, the upper plate 7 and the lower plate 8 are located in the corresponding upper groove 5 and the lower groove 6, and the driving device is used to drive the upper mold tool 3 to move upward, when the upper mold tool 3 is not in contact with the connecting rod 11, the spring rod 10 in the upper mold tool 3 is in a pulled state, and the spring rod 10 in the lower mold 2 is in the shortest state, and the upper mold tool 3 continues to move upward, the upper mold tool 3 is in contact with the connecting rod 11 and drives the connecting rod 11 to move upward together, at this time the spring rod 10 in the lower mold 2 moves upward together with the connecting rod 11, and the upper mold tool 3 The spring rod 10 in the tool 3 is still in a stretched state, but its stretched length gradually decreases. If the plate 100 is stuck on the lower mold 2, the lower plate 8 moves upward to separate the plate 100 from the lower mold 2, and the upper mold tool 3 continues to move upward until the spring rod 10 in the upper mold tool 3 is in a compressed state. At this time, the lower plate 8 is flush with the upper side surface of the lower mold 2, and the lower end of the spring rod 10 in the upper mold tool 3 extends out of the corresponding through hole 9. The upper plate 7 is disengaged from the corresponding upper groove 5, so that the plate 100 is separated from the upper mold tool 3, and the plate 100 falls onto the lower plate 8, which is convenient for removing the plate 100; then replace the next plate 100 for bending. Before the upper mold tool 3 touches the plate 100 during the downward movement, the upper plate 7 has been received in the upper groove 5, so the upper plate 7 will not produce an indentation on the plate 100.

[0017] Specifically, as shown in the figure, the driving device described in this embodiment includes a hydraulic lifting rod 20, which is powered by a hydraulic pump, controls the flow direction of hydraulic oil through a reversing valve, and realizes the lifting action by the reciprocating motion of the piston in the cylinder. The hydraulic lifting rod 20 is an existing mature technology and will not be described in detail. The hydraulic lifting rod 20 is fixedly installed on the workbench 1. In this embodiment, two hydraulic lifting rods 20 are provided and fixedly installed on both sides of the workbench 1 respectively. The movable end of the hydraulic lifting rod 20 is fixedly connected to the upper die tool 3, and the fixed end of the hydraulic lifting rod 20 is fixedly connected to the workbench 1. The movable end and the fixed end of the hydraulic lifting rod 20 move relative to each other, driving the upper die tool 3 to move up and down.

[0018] Further, as shown in the figure, the edges of the upper plate 7 and the lower plate 8 in this embodiment are close to the edges of the corresponding planes of the lower mold 2 and the upper mold cutter 3. This prevents the upper plate 7 and the lower plate 8 from causing indentations on the plate 100 when squeezing the plate 100 when the plate 100 is separated from the lower mold 2 or the upper mold cutter 3.

[0019] Furthermore, as shown in the figure, the outer periphery of the upper plate 7 and the lower plate 8 of the present embodiment is provided with an inclined surface, and the upper groove 5 and the lower groove 6 are provided with a corresponding inclined surface. The inclined surface can increase the support area of ​​the upper groove 5 and the lower groove 6 to the upper plate 7 and the lower plate 8 when the upper plate 7 and the lower plate 8 enter the corresponding upper groove 5 and the lower groove 6, so that the plane of the upper plate 7 and the lower plate 8 is subjected to a smaller pressure, thereby increasing the structural strength of the upper plate 7 and the lower plate 8; when the upper plate 7 and the lower plate 8 slide out from the corresponding upper groove 5 and the lower groove 6, the inclined surface can prevent the upper plate 7 and the lower plate 8 from being stuck in the upper groove 5 and the lower groove 6.

[0020] Furthermore, as shown in the figure, the stopper 50 is fixedly installed on the lower mold 2 in this embodiment, and the stopper 50 is symmetrically distributed on the lower mold 2. When the plate 100 is placed on the lower mold 2, the two ends of the plate 100 are respectively against the side walls of the corresponding stopper 50, and the stopper 50 can be used as a reference to place the plate 100 on the lower mold 2 as symmetrically as possible.

[0021] Furthermore, as shown in the figure, the back plates 60 are fixedly mounted on the stoppers 50 of the present embodiment, and the back plates are fixedly mounted on the rear side of the stoppers 50, and the area of ​​the back plates 60 is larger than the area corresponding to the stoppers 50. The back plates 60 can be in contact with the sheet 100, and the front side of the back plates 60 can be in contact with the rear side of the sheet 100. When the sheet 100 is placed on the lower mold 2, the presence of the back plates 60 can ensure that the sheet 100 is completely located between the lower mold 2 and the upper mold cutter 3, preventing the sheet 100 from generating waste due to offset when being bent.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
