Embodiment Construction

[0016] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.

[0017] Such as figure 1 , figure 2 , a catheter induction desoldering device, which includes an induction coil 1, an induction power supply 4, a protective copper sleeve 2 and a dismantling pliers 3 matched with the protective copper sleeve 2, the induction coil 1 is wound on the protective copper sleeve 2, the induction coil 1 and the induction power supply 4 connections.

[0018] The induction coil 1 is a water-cooled induction coil.

[0019] The desoldering method of the catheter induction desoldering device, it comprises the following steps:

[0020] (1) Install the protective copper sleeve 2 at the position of the bushing 6 on the conduit 5 that needs to be desoldered;

[0021] (2) Wind the induction coil 1 on the protective copper sleeve 2;

[0022] (3) Connect the induction...

Abstract

The invention discloses an induction duct-desoldering device and an desoldering method. The induction duct-desoldering device comprises an induction coil, an induction power supply, a protective copper sleeve and a pair of dismantling pincers matched with the protective copper sleeve, and the induction coil is wound on the protective copper sleeve, and is connected with the induction power supply. The desoldering method includes the following steps: (1) the protective copper sleeve is mounted at a bush position on a duct to be desoldered, and a bush is mounted on the duct; (2) the induction coil is wound on the protective copper sleeve; (3) the induction coil is connected with the induction power supply; (4) after water or gas is filled into the protective copper sleeve, the induction coil is utilized to heat the duct; and (5) after the duct is heated to required temperature for a required period of time, the dismantling pincers is used for moving the protective copper sleeve, so that the bush in the protective copper sleeve is separated from the duct, and thereby desoldering is finished. The invention has the advantages that the duct in an aeroengine can be unwelded and reused, the duct can be uniformly heated, the brazing quality is increased, and the requirements of the assembly, repair, product quality and the like of the engine are met.

Description

technical field [0001] The invention relates to a catheter induction desoldering device and a desoldering method, belonging to the technical field of brazing. Background technique [0002] At present, the inner ducts of aviation turbofan engines are mostly connected by brazing. Due to the special needs of the engine, such ducts must be desoldered and re-brazed. If flame brazing is used for desoldering, due to high heating temperature and uneven heating, It is easy to cause problems such as poor brazing quality and large deformation, and the catheter should not be used again after desoldering. Contents of the invention [0003] The object of the present invention is to provide a catheter induction desoldering device and a desoldering method, which can make the catheter heated evenly and improve the welding quality of brazing. [0004] The purpose of the present invention is achieved through the following technical solutions: a catheter induction desoldering device, which i...
