Embodiment 1
[0029] Embodiment 1: to the sheathed cable powder stripping of diameter 2.5mm, method is as follows
[0030] Sand blowing and powder stripping equipment: ordinary sand blowing machine;
[0031] Step 1: Load sand into the sand blowing machine with a mesh number of 330 mesh;
[0032] Step 2: Adjust the sand output pressure of the sand blower to 0.15Mp;
[0033] Step 3: Align the nozzle of the sand blowing machine with the head of the armored cable to blow sand for 15 seconds; in order to ensure the consistency of the sand blowing depth, the sand should be vertically aligned with the head of the armored cable;
[0034] Step 4: Cleaning: Use compressed air to clean the sand in the head of the armored cable;
[0035] Step 5: For steps 3-4, after 3 cycles, end.
[0036] Before loading the sand blowing machine with sand, clean it according to the use of the sand blowing machine. If the sand blowing machine is new equipment or the mesh size of the sand particles in the last use is ...

Abstract
The invention relates to a powder peeling method, and particularly discloses the powder peel method of an armoured cable. The powder peel method comprises the following steps of step1, feeding sand in a sand blowing machine, wherein the sand is 300 meshes-350 meshes; step 2, adjusting the sand outlet pressure of the sand blowing machine at 0.12Mp-0.2Mp; step 3, aligning a sand outlet gun port of the sand blowing machine with the head of the armoured cable to blow sand for 15s-20s; step 4, cleanness: cleaning sand grains in the head of the armoured cable by using the compressed air; and step 5, circulating for 3-4 times for the steps 3 and 4 and finishing. The method provided by the invention has the advantages that defects such as cable crackles, nonuniformity and difficult insulation caused by powder peeling are eliminated, the qualification rate and operational reliability of an armoured thermocouple are improved, in addition, a sand blowing powder peeling process can simultaneously perform powder peeling on tens of armoured cables, the work efficiency is improved, and the technology capability and economy type of the product are improved.
Description
technical field [0001] The invention relates to a powder stripping method, in particular to a powder stripping method of an armored cable, so that the ends of even wires in the cable can be close together to facilitate welding to form a hot node. Background technique [0002] Because the temperature-sensing material of the armored thermocouple, the wire, is isolated from the outside working atmosphere, the pollution and excessive oxidation of the thermocouple wire material can be avoided, so that the stability and working life of the thermocouple are greatly extended. In addition, the cables of armored thermocouples are generally thinner, so they are lighter in weight than traditional thermocouples. Moreover, the temperature measuring head can also be processed to be relatively small according to needs, which can meet the requirements of fast response of modern temperature measuring sensors. Therefore, armored thermocouples have begun to be widely used in aero-engines. At ...
