Abstract

The invention provides a supporting device for an internal expansion core rod for a bent pipe. The supporting device is characterized by comprising a lifting support and a driving unit for driving the lifting support to move, the driving unit can at least adjust the position along the axial direction and the vertical direction of the matching position of a pipe and the internal expansion core rod, and the lifting support can support the internal expansion core rod from the lower part. The invention further provides a bent pipe machining system comprising the supporting device. The supporting device of the internal expansion core rod for the steel bent pipe and the bent pipe machining system have the advantages that the internal expansion core rod is straightened through the lifting support, automatic assembly of the pipe is facilitated, and therefore the internal expansion core rod and the pipe can be continuously driven to move relatively to a designated position, dependence on manual straightening can be avoided, the working efficiency and safety are improved, the labor cost is reduced, moreover, the equipment transformation cost is low, only one supporting device needs to be additionally arranged in an existing pipe bending machine, the internal expansion core rod does not need to be replaced, and the service life is long.

Description

technical field

[0001] The invention relates to the technical field of pipe bending, in particular to a support device for an inner expansion mandrel for pipe bending and a pipe bending processing system. Background technique

[0002] Generally, when the hollow pipe is bent, the bending position will be deformed. At present, the cross-sectional collapse and distortion of the bent pipe are mainly limited by the inner expanding mandrel or the outer clamping structure. Among them, the inner expansion mandrel is connected by multiple universal joints, so as to have a large enough degree of bending freedom to meet the use requirements of the bent pipe. When bending the pipe, the pipe needs to be inserted outside the inner expansion mandrel first. However, The inner expansion mandrel is bent in a natural state, and it is necessary to manually align the pipe with the inner expansion mandrel before continuing to insert it into the bending position, resulting in the inability to achi...
