Referring to fig. 1-3, a plate bending machine facilitating cutter replacement includes:

the lower side of the lifting platform 100 is provided with a mounting tool holder 200, the mounting tool holder 200 comprises a vertical rear clamping plate 210, a seesaw 220 positioned on the front side of the vertical rear clamping plate 210 and an adjusting rod 230, the vertical rear clamping plate 210 is fixed on the lifting platform 100, the front side of the vertical rear clamping plate 210 is provided with a horizontal rotating shaft 211, the middle part of the seesaw 220 is rotatably connected with the horizontal rotating shaft 211, the upper part of the seesaw 220 is provided with a through hole 221, the through hole 221 is internally provided with a vertical rotating shaft 222, one end of the adjusting rod 230 is hinged with the vertical rotating shaft 222, the hinged end of the adjusting rod 230 is provided with a cam bulge 231 which is used for penetrating through the through hole 221 and is abutted against the vertical rear clamping plate 210, the lower part of the seesaw 220 is provided with a tool;

the upper part of the bending cutter 300 is provided with a clamping boss 310 matched with the cutter clamping hook 223, the clamping boss 310 is positioned on the front side of the bending cutter 300, and when the cam boss 231 abuts against the vertical rear clamping plate 210, the cutter clamping hook 223 of the lifting plate 220 presses the bending cutter 300 on the vertical rear clamping plate 210;

the upper side of the bending base 400 is provided with a V-shaped bending groove 410, and the V-shaped bending groove 410 is disposed right below the bending tool 300.

The lifting platform 100 can move up and down, and in a specific embodiment, the lifting platform 100 can be driven to lift by a power device capable of linear driving, such as an oil cylinder, an air cylinder, and the like. Vertical back splint 210 fixes the downside at elevating platform 100, and the middle part of seesaw 220 rotates through first horizontal axis of rotation 211 and connects on vertical back splint 210, has movable gap between seesaw 220 and the vertical back splint 210, lets seesaw 220 can use first horizontal axis of rotation 211 to carry out slight rotation as the center. One end of the adjusting lever 230 is hinged to the seesaw through the vertical rotating shaft 222, and the rotating shaft end corresponds to the position of the through hole 221; adjust pole 230 when rotating round vertical axis of rotation 222, through-hole 221 can be worn out by cam lobe 231, let cam lobe 231 offset with vertical back splint 210, let the upper portion of seesaw 220 rotate forward, then the lower part of seesaw 220 rotates backward, let cutter clip 223 of the lower part of seesaw 220 press backward promptly, press bending tool 300 on vertical back splint 210, let bending tool 220's lower part and vertical back splint 210 form a clip that can clip bending tool 300, accomplish bending tool 300's clamping. The tool clamp hook 223 is used for hooking the clamping boss 310 of the bending tool 300, so that the bending tool 300 can be preliminarily positioned during installation, and the bending tool 300 is more convenient to position and install; moreover, the bending tool 300 is hooked on the clamping boss 310, and the bending tool 300 cannot fall off when rising along with the lifting platform 100, so that the bending tool 300 is more stably installed, and the bending process is guaranteed. The V-shaped bending groove 410 of the bending base 400 is located right below the bending tool 300, so that when the lifting platform 100 descends, the bending blade of the bending tool 300 falls into the V-shaped bending groove 410, when the plate is bent, the plate is placed on the bending base 400, then the lifting base descends, the bending blade of the bending tool 300 is pressed on the plate, and the plate is subjected to a bending process in the V-shaped bending groove 410, so that the purpose of bending the plate is fulfilled.

When the bending tool 300 needs to be replaced, the adjusting rod 230 is rotated first, the cam protrusion 231 on the adjusting rod 230 is separated from the vertical rear clamping plate 210, that is, the adjusting rod 230 will not abut against the vertical rear clamping plate 210, the seesaw 220 can swing in a movable gap, the lower portion of the seesaw 220 will loose the clamping of the bending tool 300, the bending tool 300 can be smoothly taken off from the mounting tool holder 200, then a new bending tool 300 is mounted between the seesaw 220 and the vertical rear clamping plate 210, then the adjusting rod 230 is rotated, the cam protrusion 231 abuts against the vertical rear clamping plate 210, the upper portion of the seesaw 220 is tilted forward, the lower portion of the seesaw 220 is clamped backward, the new bending tool 300 is pressed on the vertical rear clamping plate 210, and the clamping boss 310 of the bending tool 300 is hooked by the tool clamping hook 223, so that the new bending tool 300 can be better fixed, therefore, when the bending tool 300 is replaced, a special screwdriver is not needed to unscrew or screw the bolt, so that the replacement of the bending tool 300 can be completed, the process of replacing the bending tool 300 is reduced, the replacement of the bending tool 300 is less time-consuming, the replacement efficiency of the bending tool 300 is improved, and therefore the bending machine can work normally more quickly, and the machining efficiency of the bending machine is guaranteed.

In some embodiments of the present invention, referring to fig. 1 to 3, the upper portion of the seesaw 220 is provided with an avoiding groove 224 for accommodating the adjusting lever 230, and when the cam protrusion 231 abuts against the vertical rear clamping plate 210, the adjusting lever 230 is accommodated in the avoiding groove 224. That is, when the adjusting rod 230 moves, the avoiding groove 224 does not obstruct the adjusting rod 230, and when the cam protrusion 231 abuts against the vertical rear clamping plate 210, the adjusting rod 230 is stored in the avoiding groove 224, that is, when the bending tool 300 is clamped on the vertical rear clamping plate 210 by the seesaw 220, the adjusting rod 230 is stored in the avoiding groove 224, the adjusting rod 230 is prevented from extending out of the seesaw 220, the occurrence of accidents is reduced, and the whole body is more beautiful.
