Description

U-shaped thermal shrinkage cavity for high-voltage wire harness of new energy automobile

Technical Field

The utility model relates to a pyrocondensation chamber field especially relates to a U type pyrocondensation chamber for new energy automobile high pressure pencil.

Background

In the current wire harness industry, the wire harness is processed by a heat shrinkable tube heat-shrinkable process, the heat shrinkable tube is mainly made of common PVC (polyvinyl chloride) materials, PET (polyethylene terephthalate) materials and a glue-containing double-wall heat shrinkable tube, wherein when the new energy automobile wire harness of a current heat door is processed, the glue-containing double-wall heat shrinkable tube is basically adopted in the heat shrinkable tube part, the process requirement is strict, the heat shrinkable tube can overflow glue (so as to make better wire harness waterproof performance), most of the new energy high-pressure wire harness adopts a yellow corrugated tube, the temperature resistance is low, the heat shrinkable tube is slightly careless when heat-shrinkable tube is sleeved on the heat shrinkable tube, or the heat shrinkable tube is not shrunk and the glue does not overflow, the corrugated tube is deformed, and the quality is seriously influenced; in addition, some kinds of new energy high-voltage wire harnesses are provided with sensors, the heat shrinkage pipe is nearby, the sensors are damaged after being heated by the heat shrinkage pipe carelessly during production and processing, and the conventional heat shrinkage machine in a heat gun form or a ceramic infrared/light wave heating form cannot be used for production and processing in the heat shrinkage process for the whole industry at present.

First, the first method: the hot-blast rifle, this kind of heating method is the tradition, the principle is that the heating wire blows after heating, general industrial hot-blast rifle power is every 1.8KW/2KW, when the staff carries out the heating of blowing to the pyrocondensation pipe, the temperature can promote very fast in the twinkling of an eye (aim at certain region and blow and all can exceed more than 800 ℃ in the twinkling of an eye), and influenced by external factors (temperature, humidity, wind etc.), very unstable, the staff will make the pencil insulating layer including serious deformation such as bellows of new forms of energy pencil impaired by a little careless, this kind of mode is at all not talking about the quality assurance, so also be the processing mode that whole trade at present need out urgently.

Secondly, the second mode: ceramic infrared thermal shrinkage, this kind of heating methods is the most popular heating methods at present, also be the most extensive one of thermal shrinkage equipment core heating methods adoption in whole trade, its temperature is controllable, utilize the structure of ceramic infrared heating mechanism, the heating chamber to the pyrocondensation pencil is specially designed, make the equipment heating start-up back temperature be full of whole pyrocondensation chamber, so also make external factor interference fall very low, also can make whole pyrocondensation technology become the well and have a rule through this kind of pyrocondensation chamber of fixed tool mechanism cooperation of design pencil simultaneously, the orderly of whole production technology is gone on has been guaranteed. However, the problem that the temperature displayed by the heat shrinking machine is greatly deviated from the actually detected temperature of the heat shrinking cavity under the current market environment with more intense competition is that the temperature is from plus or minus dozens of degrees to plus or minus hundreds of degrees, and the efficiency is not satisfactory. The most important problem is that the high-voltage wire harness (the heat-shrinkable efficiency is affected most) cannot be applied to the new energy automobile in the heat-shrinkable mode, because especially the heat-resistant point of the corrugated pipe is very low (generally between 70 ℃ and 120 ℃), the corrugated pipe needs to be heated through certain catalysis at a stable temperature, namely, a safe heating time is generated (the time that the corrugated pipe cannot be heated and deformed due to high temperature in the time period is ensured), so that the complete heat-shrinkable of the high-voltage wire harness of the new energy automobile is completed, the heat-shrinkable efficiency of the heat-shrinkable machine is low, the temperature is difficult to control accurately, the corrugated pipe is damaged due to thermal deformation firstly, and the heat-shrinkable pipe does not finish shrinking.

Finally, the third method: infrared light wave pyrocondensation, this kind of heating method is exactly similar to little sun baking form, has the direct heat that produces of luminous heating pipe circular telegram back, and this kind of shortcoming is very obvious, and the temperature is extremely difficult to control, as long as circular telegram, will constantly produce the heat in the twinkling of an eye, until the power limit of infrared pipe, so the problem just is obvious, and the pyrocondensation quality can't guarantee at all, and the product is damaged by the pyrocondensation very easily, and this kind of mode application range is also not very wide.

Therefore, the inventor of the present invention aims to invent a U-shaped thermal shrinkage cavity for a high-voltage wire harness of a new energy vehicle, aiming at the above technical problems.
