[0042] The inventor of the present application has found that the current bending of the plate is inconvenient and the production efficiency is low.

[0043] In order to solve the above problems, the inventor of the present application proposed the technical solution of the present application, and the specific embodiments are as follows:

Figure 4 It is a partial cross-sectional schematic diagram of a plate bending device in an embodiment of the utility model.

[0045] like Figures 1 to 4 As shown, the plate bending device of this embodiment includes: a base 1, a fixing seat 2, a tool upper die 3, a tool lower die 4 and a spring 5.

[0046] The base 1 is fixedly arranged, and the fixing seat 2 is arranged on the top surface of the base 1 .

[0047] A rectangular groove 21 is formed on the top surface of the fixing seat 2 , and the rectangular groove 21 penetrates the fixing seat 2 in the width direction.

[0048] The fixing seat 2 is provided with a through-hole 22 . There are a plurality of through-holes 22 , which are vertically arranged. The plurality of through-holes 22 are arranged at intervals along the width direction of the fixing seat 2 . The through-holes 22 of the fixing seat 2 are connected with the rectangular groove 21 .

[0049] The lower tool die 4 is slidably disposed in the rectangular groove 21 of the fixing seat 2 , and the width of the lower tool die 4 is greater than the width of the plate 10 .

[0050] A plurality of limit pins 23 are provided at the top of the fixing seat 2, and the plurality of limit pins 23 are arranged at intervals along the width direction. The plurality of limit pins 23 are arranged in a row on the outside of the rectangular groove 21 of the fixing seat 2, and the straight-line distance between the limit pins 23 and the rectangular groove 21 of the fixing seat 2 is the folding width of the plate 10 to be bent.

[0051] A plurality of springs 5 ​​are provided, and the plurality of springs 5 ​​are respectively inserted into the mounting through holes 22 of the fixing seat 2 , the top end of the spring 5 is fixedly connected to the bottom surface of the tool lower die 4 , and the bottom end of the spring 5 is fixedly connected to the top surface of the base 1 .

[0054] The hydraulic drive mechanism drives the upper die of the tool to descend. When the upper die of the tool descends, it presses down the plate and the lower die of the tool, so that the plate and the lower die of the tool move downward along the side wall of the rectangular groove of the fixed seat, so that the folding edge of the plate is bent 90 degrees to form a bent folding edge. When the lower die of the tool descends, the spring is compressed and contracted. After the hydraulic drive mechanism drives the upper die of the tool to rise, the lower die of the tool moves upward and resets under the action of the spring.

[0055] It is not difficult to find from the above contents that the plate bending device of this embodiment is provided with a base, a fixed base, a tool upper die, a tool lower die and a spring. The fixed base is provided on the base, and the fixed base is provided with a rectangular groove, a mounting through hole and a positioning pin. The tool lower die is provided in the rectangular groove, and the spring is inserted in the mounting through hole. The top and bottom ends of the spring are respectively connected to the tool lower die and the base. The tool upper die is connected to the hydraulic drive mechanism and is located above the tool lower die. In the plate bending device of this embodiment, the plate is placed on the top surface of the tool lower die, and the side of the plate is in contact with the limit pin. The hydraulic drive mechanism drives the tool upper die to descend, and the tool upper die presses down the plate and the tool lower die, so that the tool lower die moves downward along the rectangular groove of the fixed base, so that the folding edge of the plate is completed by 90° bending. After the tool upper die rises, the tool lower die is reset under the action of the spring. The folding edge of the plate is convenient and fast, which improves the production efficiency.

The top end of the guide bolt 6 engages with the first threaded hole of the tool lower mold 4 and is fixedly connected to the tool lower mold 4.

[0063] In this embodiment, when the lower die of the tool is descending, the guide bolt slides downward along the guide hole of the first fixed seat; when the lower die of the tool moves upward under the action of the spring, when the nut of the guide bolt abuts against the base, the lower die of the tool stops moving to prevent the lower die of the tool from sliding out of the fixed seat.

[0064] Furthermore, in the plate bending device in this embodiment, the second fixing seat 202 includes: a movable block 25 .

[0065] A right-angle notch is provided at the top of the second fixing seat 202 on one side close to the first fixing seat 201 .

When the folding width of the plate is different, it is only necessary to replace the movable block so that the distance between the limit pin and the side wall of the movable block corresponds to the folding width, thereby increasing the applicability and adaptability of the device.

[0067] Furthermore, in the plate bending device in this embodiment, a plurality of second threaded holes are provided at intervals on the side wall of the movable block 25 .

[0068] The side wall of the second fixing seat 202 is provided with a plurality of connecting holes, and the connecting bolts 72 are passed through the connecting holes of the second fixing seat 202 and engaged with the second threaded holes of the movable block 25 to realize the detachable connection between the movable block 25 and the second fixing seat 202, thereby facilitating the installation and removal of the movable block 25.

[0070] Furthermore, the plate bending device in this embodiment also includes: a limiting side plate 8.

[0071] The limiting side plate 8 is arranged on the side wall of the tool upper die 3, and the bottom surface of the limiting side plate 8 is lower than the bottom surface of the tool upper die 3. When the tool upper die 3 descends, the side wall of the limiting side plate 8 abuts against the side wall of the fixing seat 2 and moves downward along the side wall of the fixing seat 2.
