Analyze the rolling process of the pipe bender on the workpiece

The pipe bending machine company prompts the use of rolling straightening, which is generally completed in the process of rolling the workpiece, so that not only the surface of the workpiece will not be damaged, but also the outer surface of the workpiece can be more uniformly rolled. No dead bends, easy to operate. The pipe bending machine analyzes the rolling process of the workpiece: in the process of rolling the workpiece, the rolled workpiece is bent due to the uneven hardness of the surface layer under the action of external force. The high position of the bending rotation center bears high rolling pressure, and the resulting plastic deformation is also large, which increases the degree of bending of the workpiece. Especially when using rigid rolling T tools, this phenomenon is more prominent. The length of the knife passed after the second time should be based on the specific situation, and it is not necessary to complete the entire process, and the reverse knife should be used. Description of the installation method of the tube bending machine mold: wheel horizontal BENDING DIE; installation: counterclockwise, put the wheel mold fixing nut FIG-71; remove and put the wheel mold, and then lock the wheel mold fixing nut to lock the clamp CLAMP DIE; installation: Pull out the clamp mold to fix the centering shaft FIG-72, put the clamp mold in, and then insert the fixed mandrel. Adjustment: Fix the clamp mold seat FIG-73; relax, then put the control panel in manual mode, press the clamp pipe button FIG-73, to the end of the clamp mold path, at this time, there needs to be a gap between the wheel mold clamp and the clamp can be clamped. Die seat adjustment screw FIG-74 to adjust. The method of rolling and straightening is to check the radial runout of the workpiece after rolling the workpiece for the first time, mark around, and use a four-jaw chuck to adjust the recess of the workpiece to the height of the turning center of the machine tool. It is proportional to the size of the bending of the workpiece, and then rolls the second time, and then use the dial indicator and adjust the jaws of the four-jaw chuck to correct the workpiece. Then use the dial indicator to check the bending condition. If it is still bent, use the above method to adjust the workpiece and carry out the third rolling until it reaches the required straightness of the workpiece.
