A fast automatic tube expansion machine

Abstract

The invention relates to a pipe drawing and pipe expanding machine, in particular to a quick and automatic pipe drawing and pipe expanding machine. The quick and automatic pipe drawing and pipe expanding machine comprises a rack and controller. A first worktable, a tool rest, a material table and a second worktable are sequentially arranged on the rack. A movable material bracket is arranged on the first worktable, and a feeding air cylinder is arranged on the material bracket. An electric cutter is arranged on the tool rest. A connected work bracket is movably arranged on the second worktable. The connected work bracket comprises a first work bracket, a second work bracket, a third work bracket and a fourth work bracket, a pipe cutting device is arranged on the first work bracket, a pipe drawing device is arranged on the second work bracket, a pipe expanding device is arranged on the third work bracket, and a reaming device is arranged on the fourth work bracket. Compared with the prior art, the quick and automatic pipe drawing and pipe expanding machine has the advantages that pipe cutting, pipe drawing, pipe replacing and pipe expanding of a single damaged heat exchange pipe in a heat exchanger can be completed automatically, and the problem that the whole heat exchanger can be scrapped after a certain heat exchange pipe in the heat exchanger is damaged is solved; meanwhile, the problems that the efficiency of manual pipe replacement operation is low and other components of the heat exchanger can be damaged are solved.

Description

Technical field [0001] The invention relates to a pipe-drawing and expanding machine, in particular to a pipe-drawing and expanding machine for heat exchange tubes. Background technique [0002] In the heat exchanger production process, several metal tubes and the fins set on it need to be tightly combined. At this time, the metal tube needs to be expanded to expand the diameter of the metal tube to make it match the fins. The fins are tightly connected to avoid looseness and increase the heat conductivity of the heat exchanger, so that good heat transfer and heat conduction can be ensured. At present, most pipe expansion operations adopt automatic pipe expansion, which is fast and efficient, and is suitable for mass production. When the tube is expanded, it will cause defects in part of the pipeline, such as rupture and deformation of the pipeline; after this happens, the entire product must be scrapped, causing a lot of loss. In order to reduce the loss, the damaged pipeline ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the present invention provides a fast automatic tube extraction and expansion machine, which can automatically complete the work of tube cutting, tube extraction, tube replacement, and tube expansion for individually damaged heat exchange tubes in the heat exchanger. It solves the problem that the whole heat exchanger will be scrapped after a certain heat exchange tube in the heat exchanger is damaged in the past

At the same time, it also solves the problem of low efficiency of manual tube replacement and damage to other parts of the heat exchanger.
