Description

TECHNICAL FIELD

[0001] The present application relates to the field of cable processing, in particular to a cable fluoroplastic insulation sleeve roughening device and a roughening process method. BACKGROUND

[0002] The high-temperature cable for aerospace is usually composed of a conductor, a fluoroplastic insulation layer, a sheath, a shielding structure and the like. The main function of the shielding is to reduce the leakage of the internal transmission signal of the cable, so as to make the information transmission safer, and also to reduce the electromagnetic radiation pollution of the cable to the outside. At the same time, it can effectively prevent the external electromagnetic field from interfering with the internal signal of the cable, thereby ensuring the quality of signal transmission. The fluoroplastic insulation layer needs to be roughened by sand blasting in the processing process, so that the surface of the fluoroplastic is in a micro-rough state, the surface energy is increased, the surface activity is improved, and the fluoroplastic has strong ion adsorption capacity. The roughness of the surface is the key to determining the adhesion of the metal coating. The existing sand blasting equipment can easily roughen the surface of the fluoroplastic insulation sleeve, but in order to further improve the shielding performance of the fluoroplastic insulation layer, it is necessary to perform metal coating treatment on the inner and outer walls of the fluoroplastic insulation sleeve. Since the fluoroplastic insulation sleeve is relatively long, it needs to be straightened when sand blasting inside, and then connected with the sand blasting head for internal sand blasting roughening. However, this method occupies a large area, and if the insulation sleeve is bent, the sand blasting is easy to be blocked at the bending part. SUMMARY
