Sheet metal shell processing, riveting is also the key

Release date:2017-09-03 Author:Source Network Click:

Sheet metal processing shell, in order to be able to better fix the PCB board, the housing needs riveting, pressure riveting is the key, if not a good pressure, with the hole on the PCB board up, then the shell can not Re-use, therefore, sheet metal processing, we should pay attention to the method of riveting, but Dalian sheet metal rivet should pay attention to what?

    1 for the product near the edge of the hole or hole near the riveting pressure riveting will cause significant distortion of the edge of the product or around the hole, according to the deformation of the situation to take the appropriate measures (such as school shape / or polished) to achieve the drawings Size, appearance requirements.

    2. After the riveting pressure should not appear crooked, pressure deviation phenomenon, we must ensure that the thread and its corresponding hole is concentric.

    3 pressure riveting pieces of material, specifications and models must be consistent with the drawings, not the wrong pressure specifications;

    4. Riveting pressure riveting around the bump or convex or not obvious deformation, may not have obvious surface treatment can not cover the imprint or mold imprint.

    5. Riveting shall not be tilted after the riveting parts shall not be loose, fall off, we must test its firmness; its push-pull and torque values must meet the specifications of riveting parts PEM requirements.

    6 pressure riveting must promptly confirm the production line with the pressure riveting outside the logo and the bag in the physical (material, specification model) is consistent with the drawing requirements, the bag is mixed material phenomenon.

    7. In the bending edge or mold forming the edge of the riveting parts to be focused on, especially the thread, the appearance (deformation) to focus on testing.

    8. After the riveting riveting parts on the product quality, specifications and thread random sampling, whether the drawings meet the requirements, with or without leakage pressure, the wrong pressure, the location of the wrong pressure, the phenomenon of mixed.

    9. Riveting pressure riveting after the thread must be qualified, pass through regulations, only regulations.

    10. Riveting is completed after the test is required to check whether the flatness within the scope, if excessive need to be transferred to fitter-shaped processing.

    11. A single product Rivet studs, the number of screws are more, some products will be made of special fixture for riveting, the other need to do a special fixture to check whether there is leakage pressure or wrong pressure and other defects.


Sheet metal is a sheet metal processing products. Sheet metal parts are produced by filament power winding, laser cutting, heavy-duty machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, water jet cutting, precision welding .

Sheet metal definition: Sheet metal is a comprehensive cold-working process for sheet metal (usually below 6mm), including shearing, punching / cutting / compounding, folding, welding, riveting, splicing, forming such as automobile bodies. The salient feature is the same part thickness.
