The current CNC pipe bending machine has strong advantages and many features. We cooperate with many technologies. The current CNC pipe bending machine cuts the steel pipe easily and uses high-speed steel blades with extremely high hardness at high speed. It cuts into the steel pipe layer by layer until it is cut. The CNC pipe bending machine utilizes a unique knife-rotating feed principle. The cutter rotates around cold-rolled steel pipes, hot-rolled steel pipes, carbon steel pipes, alloy steel pipes, forged steel pipes, cast steel pipes, and other types of steel pipes. So what is the feeding mechanism of the CNC pipe bending machine? Taiwan and machinery experts to answer you:
The pipe bending head can move laterally along the guide rail. This is necessary to adjust the pipe groove of the pipe bending machine to align with the center line of the machine tool after changing the bending die. This is easier than adjusting the center line of the machine tool by adjusting the guide rails and tailstock on the bed.
Complete the linear feed movement (DBB) of the cart, in the process of bending the tube, the tube is pulled forward. In this way, the “positive thrust” is removed, thereby eliminating the synchronization problem between the trolley and the bending speed, and the DC motor negative feedback system set to increase the “positive thrust” is removed, simplifying the electrical circuit.
Automatic pipe bending machine is beneficial to the bending of the pipe because of the positive thrust, especially when bending a pipe with a large diameter, the positive thrust is necessary. Therefore, the VB pipe bender adds a booster device.
Because the cart is used as a load, it is pulled forward by the tube. In order to improve the bending, the wall thickness of the bent part of the tube is not excessively thinned, the rebound is reduced, and the booster device is added. When bending, the die not only compresses the tube, but is also pushed forward by the boosting force to form a side thrust for bending.
The bending arm and the bending main shaft are connected together, the bending die axis can be replaced, and the clamping die moves up and down, which not only has a reasonable structure, increases the strength of the mechanical part, but also has a simple structure, which simplifies the electrical circuit.
When the CNC bending machine enters the last bend, the trolley may collide with the stamper. At this time, the “interference zone” function can be used, that is, the stamper returns → the trolley continues to feed → the bent arm returns → the space corner (POB) → Clamping die clamping → chuck unclamping, the trolley exits the interference zone → compression die pressing → bending the tube. In this way, not only the collision between the trolley and the stamping die is avoided, the smooth completion of the last bend is ensured, but also the clamping loss of the material head can be reduced and the production cost can be reduced.
