How to adjust the bending machine quickly to adapt and ensure the bending requirements of the aluminum profile and the stable bending state. It can be seen from the schematic diagram that in order to adapt to the adjustment of the aluminum profile and the bending process parameters, several main components of the bending machine should be able to Make macro adjustments and fine-tuning. These components include: l) stroke adjustment and precise displacement control of the guide block; 2) adjustment and precise positioning of the indexing angle of the fixed mold wheel; 3) rapid replacement and precise positioning of the fixed mold wheel to adapt to changes in the specifications of the aluminum profile ; fast movement and axial fine adjustment of the support mandrel; 5) clamping stroke and clamping force adjustment of the clamping block. From the analysis of the motion characteristics of several parts of the bending machine, the mechanism of motion of the bending machine includes two kinds, one is the mechanism with rapid movement and precise positioning, such as the guiding block, the shaping die wheel, the movement of the supporting mandrel and the shaping die. The rotation of the wheel, etc.; one is a mechanism with fast motion and adaptive position, such as the movement of the clamping block. For the former form of motion, the position of the moving mechanism is required to be high, and the position must be consistent during the bending process of the aluminum profile under the action of external force. For the second form of motion, the mechanism should have an adaptive ability to change the thickness of the clamping portion of the aluminum profile and maintain the clamping force during the bending process. According to the above analysis, the structure design of the CNC bending machine adopts two types of structures, one is a mechanism with fast motion and precise positioning, and the motion mechanism of stepping motor driving, harmonic deceleration, and screw nut transmission is uniformly adopted. According to the position and bearing capacity of each mechanism, choose harmonic reducers and guide clamping components with different specifications. The other is the clamping mechanism, which uses the piston cylinder clamping mechanism to achieve workpiece clamping and clamping position adaptation.
The control scheme of the CNC bending machine is determined, which is highlighted in the flexible control of the bending machine. According to the changes in the specifications and materials of the aluminum profiles, it is convenient and quick to adjust and position each of the adjustment mechanisms. To this end, we have adopted the control system with the 8051 series single-chip microcomputer as the core, and the human-machine interface adopts multi-window debugging mode for high-level language. All operations are driven by a drop-down pop-up menu. Overall structural design The overall structural layout of the CNC bending machine adopts a T-shaped structure. Considering the simple and beautiful appearance of the device, for the mechanism with fast motion and precise positioning, the driving components, stepping motor and reducer are installed under the T-shaped table. In order to ensure the precise positioning of the mechanism, a synchronous toothed belt connection method is adopted between the output shaft of the reducer and the drive screw of the actuator, so that the three-dimensional space can be fully utilized under the bending machine T-shaped worktable, and the four are arranged reasonably.
