Hydraulic pipe bending machine is a new type of pipe bending tool with pipe bending function and lifting function. It has many advantages such as reasonable structure, safe use, convenient operation, reasonable price, fast loading and unloading, easy to carry, and one machine for multiple purposes. It occupies a large share in the domestic hydraulic pipe bending machine market, mainly used in factories, warehouses, docks, Installation of pipes and repairs for railways, automobiles, etc. In addition to the pipe bending function, it can also be used as a separate hydraulic jacking machine by removing the pipe bending parts (oil cylinder).
Now, the processing technology of hydraulic pipe bending machine in my country has sprouted from the Bronze Age, and has gradually formed and developed. Today, it has developed relatively maturely. The hydraulic pipe bending machine has the following three mechanical characteristics.
Features of hydraulic pipe bender
1. The pipe bending machine adopts a touch screen and a numerical control module, which is operated in a conversational manner, and the program setting is simple and easy.
2. The bed structure is stable and not easy to deform.
3. Each file can set 16 elbow angles, and the memory can store 16 sets of files.
4. All functions of slow positioning, stable bending angle and repeatability of ±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 bending processing value. The software can be installed on the desktop computer for editing and calculation.
7. The trolley that completes the linear feeding motion (DBB) is pulled forward by the pipe during the bending process of the pipe. 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", which simplifies the electrical circuit.
8. When bending, because the trolley acts as a load, it is pulled forward by the tube. In order to improve the bending, it is necessary to avoid excessive thinning of the wall thickness of the bending part of the tube, reduce the rebound, and increase the booster device. When bending, the die not only compresses the tube, but also is pushed forward by the thrust force to form a side thrust that assists the bending.
9. The elbow head can move laterally along the guide rail, which is necessary for the bending machine to adjust the bending die tube groove to the center line of the machine tool after changing the bending die. This is easier than adjusting the centerline of the machine tool by adjusting the guide rails and tailstock on the bed.
