A kind of internal flanging and solidification method of heat-shrinkable tube

Abstract

The invention discloses a setting method for an inner flanged edge of a heat shrink pipe. The setting method comprises the following steps that S10, a to-be-sleeved object is sleeved with the heat shrink pipe, one end of the heat shrink pipe extends out of the corresponding end of the to-be-sleeved object by a certain distance, and the part, extending out of the corresponding end of the to-be-sleeved object by the certain distance, of the heat shrink pipe is a to-be-shrunk part; S20, the to-be-shrunk part is heated until the to-be-shrunk part is heated to be shrunk to obtain a shrunk part; andS30, the shrunk part is pressed into the to-be-sleeved object by adopting a setting module, the shrunk part undergoes cooling and setting, the setting module is removed from the to-be-sleeved objectto obtain an inner flanged edge finished product. According to the setting method, special-shaped processing of the heat shrink pipe can be realized, the phenomenon that the heat shrink pipe restoresto an original shape or partially deforms in the processing process is avoided, the obtained heat shrink pipe can perform rapid positioning on a to-be-sealed object, and the installation efficiency ofthe heat shrink pipe is improved.

Description

technical field [0001] The invention relates to the technical field of a flanging method for a heat-shrinkable tube, in particular to an inner flanging and solidifying method for a heat-shrinkable tube. Background technique [0002] In many products today, heat-shrinkable tubes are placed on some parts for sealing, such as exposed parts of wire connections or tubular parts. [0003] When the heat-shrinkable tube is placed on the product, it is often necessary to locate the position of the heat-shrinkable tube, and this positioning operation is generally achieved by manual alignment, which is a waste of time in the actual operation process, resulting in the installation of the heat-shrinkable tube The efficiency is low. Therefore, it is necessary to carry out special-shaped treatment on the heat-shrinkable tube, which is used for product coating, insulation, protection, etc. The heat-shrinkable tube maintains a certain shape after extrusion or injection molding. If you direc...

[0003] When the heat-shrinkable tube is placed on the product, it is often necessary to position the position of the heat-shrinkable tube, and this positioning operation is generally achieved by manual alignment, which is a waste of time in the actual operation process, resulting in the installation of the heat-shrinkable tube The efficiency is low. Therefore, it is necessary to carry out special-shaped treatment on the heat-shrinkable tube, which is used for product coating, insulation, protection, etc. The heat-shrinkable tube maintains a certain shape after extrusion or injection molding. If you directly use hard pressure, warping, etc., the heat shrinkable tube will return to its original shape, or partially deformed in the desired shape, resulting in the heat shrinkable tube not achieving the desired positioning effect
