[0002] In industrial production, it is often necessary to process plates. A bending machine is a device that can bend plates. It is mainly used in automobile manufacturing, daily necessities processing, aviation manufacturing, shipbuilding and other fields.

[0003] The currently published patent: CN219724188U discloses a plate bending machine, which can drive the movable plate to rotate relative to the extrusion table through a rotating shaft. When the aluminum plate of a specific angle needs to be processed, it only needs to rotate and lift the movable plate to a corresponding angle with the extrusion table, and then a fixing rod can be inserted through a plurality of through holes on the support plate and a fixing hole on the movable plate to achieve the effect of fixing the movable plate at a corresponding angle. Through the above scheme, the aluminum plate of the required angle can be bent simply, intuitively and accurately, thereby increasing the scope of application of the device.

[0004] Based on the above search, it was found that the above patent has the following problems when in use: the plate bending machine can adjust the angle between the movable plate and the extrusion table when in use, but the movable plate can only be rotated to a position where the fixing hole on its surface corresponds to the through hole opened on the support plate surface, and the fixing rod can be inserted therein to achieve the effect of fixing the movable plate at the corresponding angle. Therefore, only a few fixed angles can be adjusted. Not only is the range of adjustment of the angle very small, but the staff also needs to fix it with the fixing rod, which makes the fixing method of the movable plate more cumbersome, reducing the convenience of using the plate bending machine. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plate bending machine with an adjustable lower pressure plate, comprising a bending stand and a plate bending adjustment mechanism; the top of the bending stand is fixedly connected to a support frame, and the top of the support frame is fixedly connected to a loading top plate; the plate bending adjustment mechanism comprises a rotating rod, a lower pressure plate, a three-way rotating rod, a hydraulic press and a protrusion, the rotating rod is rotatably connected to the right end of the loading top plate, the lower pressure plate is fixedly sleeved on the surface of the rotating rod, a groove is opened on the surface of the support frame, the three-way rotating rod is rotatably connected to the inside of the groove, and the hydraulic press is fixedly installed on the surface of the three-way rotating rod.

[0026] When the sheet metal bending machine is in use, the staff first puts the sheet metal into the limiting slot 7, and then slides the sheet metal to the right to the length required for bending, and starts the hydraulic bender 10. The output end of the hydraulic bender 10 drives the upper pressure plate 11 to slide downward to squeeze the surface of the sheet metal to complete the bending, and the telescopic cylinder 9 can drive the hydraulic bender 10 and the upper pressure plate 11 to move left and right to adjust the position, and then bend the sheets of different bending lengths. The sheet metal is limited and fixed by the limiting card plate 6 to ensure the stability of the sheet metal bending, and the sheet metal is fitted with the top wall of the limiting slot 7 to prevent the sheet metal from tilting upward, thereby improving the bending quality of the sheet metal.

[0028] When the staff needs to bend the plate to different angles, the staff can start the hydraulic press 15. The movement of the output end of the hydraulic press 15 can drive the lower pressure plate 5 to rotate through the protrusion 16. The lower pressure plate 5 rotates and drives the rotating rod 4 to rotate inside the loading top plate 3.
