[0025] like Figure 1-Figure 3As shown, a CNC hydraulic bending machine for aluminum veneer proposed by the utility model includes a frame 1, a driving assembly, a bracket 7, a transmission assembly and a lifting drive. The frame 1 is rotatably connected to the support roller 4, and a plurality of shaping grooves 401 are arranged in a ring array around its axis on the support roller 4. A circular groove 101 with an opening upward is arranged on the frame 1, and the support roller 4 is located in the circular groove 101 and is slidably connected with its inner wall. A guide roller 2 for supporting the aluminum veneer is arranged on the frame 1, and the top section of the guide roller 2 is on the same plane as the upper end surface of the shaping groove 401 with an opening upward. Among them, the shaping groove 401 includes V-shaped grooves, arc grooves and special-shaped grooves with different angles. The driving assembly includes but is not limited to a motor 5, the support roller 4 is connected to the rotating shaft A3, the rotating shaft A3 is rotatably connected to the frame 1, the motor 5 is connected to the frame 1, and the output end of the motor 5 is connected to the end of the rotating shaft A3, and the motor 5 drives the support roller 4 to rotate to switch to the corresponding shaping groove 401 with the opening facing upward. The bracket 7 is connected to the frame 1, the bracket 7 is slidably connected to the U-shaped plate 8, the U-shaped plate 8 is rotatably connected to the installation roller 10, and a plurality of stamping piers 11 are arranged on the installation roller 10 in a ring array around its axis, and each stamping pier 11 is respectively adapted to the corresponding shaping groove 401. The transmission assembly is connected to the support roller 4 and the installation roller 10 so that the installation roller 10 is driven to rotate synchronously while the driving assembly drives the support roller 4 to rotate, and the stamping pier 11 is kept corresponding to the corresponding shaping groove 401. The transmission assembly includes a bevel gear A402, a rotating shaft B6, a bevel gear B602, a bevel gear C603 and a bevel gear D1001. The bevel gear A402 is connected to the rotating shaft A3, the rotating shaft B6 is rotatably connected to the frame 1 and the bracket 7, and the rotating shaft B6 is slidably connected to the U-shaped plate 8. The bevel gear B602 is connected to the rotating shaft B6 and is vertically meshed with the bevel gear A402. The bevel gear C603 is coaxial with the rotating shaft B6, and the bevel gear C603 is slidably connected with the rotating shaft B6, and a slide groove 601 is provided on the rotating shaft B6 for preventing the bevel gear C603 and the rotating shaft B6 from rotating relative to each other. The bevel gear D1001 is connected with the roller shaft of the installation roller 10 and is coaxial therewith, and the bevel gear D1001 is vertically meshed with the bevel gear C603, and the bevel gear C603 and the bevel gear D1001 are both rotatably connected with the U-shaped plate 8 and slide up and down with the U-shaped plate 8. The lifting drive includes but is not limited to the hydraulic cylinder 9, the cylinder barrel of the hydraulic cylinder 9 is connected with the bracket 7, and the push rod of the hydraulic cylinder 9 is connected with the U-shaped plate 8. The hydraulic cylinder 9 drives the U-shaped plate 8 to rise and fall, and when the U-shaped plate 8 is in the rising or falling state, the transmission assembly keeps the support roller 4 and the installation roller 10 rotating synchronously.

[0026] In this embodiment, firstly, an appropriate shaping groove 401 is selected according to actual needs, and then the motor 5 is started. The motor 5 drives the support roller 4 to rotate until the shaping groove 401 opens upward. During the process of the motor 5 driving the support roller 4 to rotate, the rotating shaft B6 rotates synchronously under the meshing transmission of the bevel gear A402 and the bevel gear B602, thereby driving the bevel gear C603 to rotate, and the bevel gear C603 drives the bevel gear D1002 and the installation roller 10 to rotate. Since the stamping pier head 11 is aligned with the shaping groove 401 one by one, the bevel gear C603 drives the bevel gear D1002 and the installation roller 10 to rotate. Correspondingly, the rotation angle of the installation roller 10 is the same as that of the support roller 4. At this time, the stamping pier 11 corresponding to the current upward-opening shaping groove 401 is just facing downward. Then, the aluminum veneer to be bent is placed on the guide roller 2, and the aluminum veneer is moved so that the point to be stamped is exactly located at the center of the shaping groove 401. The hydraulic cylinder 9 is started, and the hydraulic cylinder 9 presses down the U-shaped plate 8 and drives the installation roller 10 and the stamping pier 11 to slide downward. The stamping pier 11 cooperates with the shaping groove 401 to bend the aluminum veneer into the required shape. During the lifting and lowering process of the U-shaped plate 8, since the bevel gear C603 and the bevel gear D1002 rise and fall synchronously with it, the installation roller 10 will not rotate freely during the lifting and lowering process.

[0029] In this embodiment, after the pier head is damaged, the corresponding limit pin 12 can be pulled out. After the limit pin 12 is pulled out from the pin hole, the locking restriction on the plug plate 111 is released. At this time, the entire stamped pier head 11 can be directly removed. This structure makes the removal and replacement of the stamped pier head 11 simple and convenient.
