Pipe bender and bending method using pipe bender

Abstract

The invention relates to a pipe bender, comprising a worktable, a feeding mechanism, a compacting mechanism and a pipe bending mechanism; the pipe bending mechanism comprises a mandrel fixed on the worktable, and a first roller and a second roller both of which are vertically arranged on the worktable; a plurality of guide structures are arranged on the worktable and located symmetrically on both sides of the mandrel head; the guide structures extend from the root part of the mandrel head to the tail end along the contour line of the mandrel head, and two extreme positions of the guide structures respectively correspond to the root part and the tail end of the mandrel head; the bottom parts of the two rollers are respectively slidably arranged on the corresponding guide structures; and the worktable further is provided with a driving mechanism used for respectively driving the two rollers to reciprocate between the two extreme positions of the guide structures so as to roll and bend the pipes. The invention further relates to a bending method using the pipe bender. The problem that the pipe bending mechanisms in the prior art bend the pipes only in one direction is solved.

Description

technical field [0001] The invention relates to a pipe bending machine and also relates to a bending method using the pipe bending machine. Background technique [0002] For heavy-duty tank trucks and coal trucks, in order to ensure safety, square tubes must be used for the penetrating beams. However, due to some technical difficulties in bending square tubes, most companies still use square tubes and parallel irons. This not only increases the cost, but also makes the entire vehicle body heavier and the risk factor increases. [0003] At present, the mechanical pipe bending industry often adopts bending methods such as push bending, pulling bending, winding bending, and pressing bending to process bends. The bending mechanisms used are all one-way bending mechanisms. If a pipe needs to be bent in multiple directions In this case, it can only be solved by changing the material, which is labor-intensive, and the process of changing the material affects the machining accuracy...
