Do you know the five mechanical characteristics of the automatic pipe bending machine?

With the continuous development of the automatic pipe bending machine industry, the automatic pipe bending machine is widely used in aerospace, automobiles, locomotives, motorcycles, ships, petrochemicals, electric power, natural gas, and nuclear because of its high precision, stable performance, simple and safe operation. Bending processing of pipe fittings for industry, boilers, vehicles, fitness equipment, sporting goods, etc. So do you know the five mechanical characteristics of the automatic pipe bending machine? Taiwan and machinery experts tell you:

1. The trolley that completes the linear feed motion (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 problem of synchronization between the trolley and the bending speed, and the negative feedback system of the DC motor set to increase the “positive thrust” is removed, and the electrical circuit is simplified.

2. The elbow head can move horizontally along the guide rail. This is necessary for the pipe bending machine to adjust the pipe groove of the bending die to align with the centerline of the machine tool after the bending die is replaced. This is simpler than adjusting the centerline of the machine tool by adjusting the guide rail and tailstock on the bed.

3. When bending, the trolley is used as a load and is pulled forward by the tube. In order to improve the bending, avoid excessive thinning of the wall thickness of the bending part of the tube, reduce springback, and increase the booster device.

4. When entering the last bend, the trolley may collide with the die. At this time, the “interference zone” function can be used, that is, the die returns → the trolley continues to feed → the elbow arm returns → the space corner (POB) → the clamping die Clamping→releasing the chuck, the trolley exits the interference zone→compressing the die→bending the pipe. In this way, the bend not only avoids the collision between the trolley and the die, and ensures the smooth completion of the last bend, but also reduces the clamping loss of the material head and reduces the production cost.

5. The pipe bending arm and the bending spindle are connected as a whole, the pipe bending mold axis can be replaced, and the clamping mold can move up and down. This not only has a reasonable structure, but also increases the strength of the mechanical part. It also has a simple structure, which simplifies the electrical circuit.
