CNC tube bending machine
The structure is reasonable and reliable, and has sufficient strength, rigidity and longevity. The frame is processed by the internal tempering and vibration aging process to eliminate internal stress. The selected mechanical, pneumatic, electrical, electronic components and automatic control systems are advanced, high quality and reliable products. Under the conditions of ambient temperature -5 °C ~ 45 °C, relative humidity ≤ 90%, rated load, etc., the CNC tube bending machine can achieve stable two-shift operation, the hydraulic system has no leakage, and the product precision is stable. The equipment is equipped with emergency stop switches on the electrical cabinets and consoles, and all parts of the machine have reliable safety protection and measures. With human-machine interface dialogue operation, all parameter data can be input through the touch screen. The pipe bending machine has perfect interference check and self-protection function. Before the program is executed, the safety check can be carried out according to the input mold parameters and processing program parameters. If there is interference, an alarm message is required to prompt the operator. It has a complete fault alarm function and displays alarm information on the screen, which is convenient for the operator to find and troubleshoot. The wire arrangement of the device is neat and waterproof, and the pipeline arrangement is neat and beautiful. The mechanical and electrical parts have reliable safety protection interlocks and self-protection functions such as overvoltage, overcurrent, overheating, short circuit, open circuit and leakage protection, power failure or unplanned shutdown.
1. The pipe bending machine adopts touch screen and numerical control module, and the dialogue operation is simple and easy to set.
2. The bed structure is stable and not easy to deform.
3. Each file can be set with 16 bend angles, and the memory can store 16 sets of files.
4. Slow speed positioning function, the angle of the bend is stable, the repeatability is up to 0. 1 °
5. The error message is displayed on the screen to help the operator to eliminate it immediately.
6. Provide self-developed coordinate conversion elbow processing value, software can be installed and edited on the desktop computer.
7. The trolley that completes the straight-line feeding movement (DBB) is pulled forward by the tube during the bending process of the tube. In this way, the "positive thrust" is removed, thereby eliminating the synchronization problem between the trolley and the bending speed, and removing the DC motor negative feedback system provided for increasing the "positive thrust", simplifying the electrical circuit.
8. The elbow head can be moved laterally along the guide rail. This is necessary after the bender is adjusted to adjust the bending slot of the machine to the center line of the machine. This is simpler than adjusting the machine centerline with the guide rails and tailstock on the adjustment bed.
9. When bending, as the trolley acts as a load, it is pulled forward by the pipe. In order to improve the bending, the wall thickness of the curved portion of the pipe is prevented from being excessively thinned, the rebound is reduced, and the boosting device is added.
10. When feeding the last corner, the car may collide with the die. At this time, the “interference zone” function can be used, that is, the die is returned → the car continues to feed → the elbow arm returns → the space corner (POB) → the clamping die Clamping → The chuck is released, the trolley exits the interference zone → the stamper is pressed → the tube is bent. In this way, the curved pipe not only avoids the collision of the trolley with the stamper, but also ensures the smooth completion of the last bend, and can reduce the clamping loss of the material head and reduce the production cost.
11. The elbow arm and the bending main shaft are integrated, the curved bending mold shaft can be replaced, and the clamping mold moves up and down. This not only has a reasonable structure, but also increases the mechanical part strength, and the structure is simple, so that the electric circuit is also simplified.
