Abstract
The invention provides a production technology of a PTC heating pipe. After the stirring of glue, the screening of ceramic pieces, the placement of electrode strips, the penetration of a pipe and the rolling forming, the method carries out subsequent processing, and detects the heating pipe for many times in a production process, thereby improving the production efficiency of the PTC pipe, improving the quality of the PTC heating pipe, and prevents unqualified products from flowing into a market.
Description
Technical field
The present invention relates to the production field of heating tube, specifically a kind of PTC heating tube production technology.
Background technology
PTC heating tube is by inner member thermistor heating power, easily go wrong in process of production and cause PTC heating tube not reach corresponding heating effect, can not meet customer need, immature to the production technology of PTC heating tube at present, easily cause underproof PTC pipe to produce, solve the problem and seem particularly necessary.
Summary of the invention
The invention provides one in order to solve the problem and repeatedly dielectric strength detection be carried out to heating tube in process of production, after load module, carried out comprehensive detection, the PTC heating tube production technology of PTC heating tube quality can be ensured.
The present invention is achieved through the following technical solutions in order to achieve the above object:
Step one: heating wire is carried out bonded adhesives stirring, the heating wire after being stirred by bonded adhesives carries out drying, clearing up, and clears up aluminum pipe stock, dries, then by heating wire string on aluminum pipe;
Step 2: potsherd is screened, then screening is carried out to the qualified potsherd of screening, namely potsherd is come on the obtained aluminum pipe of step one;
Step 3: carry out putting electrode strip on the aluminum pipe that step 2 is obtained, brush coating, lid electrode strip are carried out to the electrode strip be well placed, then turnover panel is carried out to electrode strip;
Step 4: the heating tube obtained to step 3 carries out bag dielectric film and poling, carries out closed tube, carry out roll-forming with roll squeezer to heating tube to the heating tube that poling completes;
Step 5: the heating tube shaping to step 4 carries out dielectric strength test by dielectric strength detector, removes underproof heating tube;
Step 6: carry out brush coating to heat sink strip, is fixed to heat sink strip on qualified heating tube that step 5 obtains, and puts heat generating core, then the solidification that is energized, and carries out proof voltage test to the heating tube after solidification;
Step 7: carry out power test to the heating tube of proof voltage test passes in step 6, the heating tube qualified to power test carries out a rubber seal mouth.
Further improvement of the present invention is: further comprising the steps of:
Step 8: laser marking and visual examination are carried out to the heating tube that step 7 obtains, subsequently dielectric strength test is carried out to qualified heating tube;
Step 9 a: glue is carried out to the heating tube of test passes in step 8, in heating tube support, some glue, is installed to normal temperature cure after on support by heating tube;
Step 10: by heating tube obtained for fuse, thermostat and line group inserting step nine, put heat-shrink tube subsequently, then heat-shrink tube is warmed;
Step 11: the heating tube obtained to step 10 carries out overall appearance inspection and electrical resistance integration test, packs and piling the heating tube of test passes.
Beneficial effect of the present invention: the present invention by bonded adhesives stir, potsherd screening, put electrode strip, poling, roll-forming after carry out subsequent treatment, repeatedly heating tube is detected in the process of producing, not only increase the production efficiency of PTC pipe, improve the quality of PTC heating tube simultaneously, avoid substandard product to come into the market and work the mischief.
