The side wall of the box body is a heat sink, and the exposed end of the heat radiating fin can not damage the surface, and the inner surface is made of four M3h6 internal thread nut columns, which is welded? Or press riveting? Heat sink is extruded aluminum profile, the thickness of 5.5mm, slotted deep 2.5mm, how should this process? Do you have this nut column?
Let me seeGenerally speaking, there are more riveting nuts,Threads are also drilled and tapped and threaded with steel threadBut according to the actual situation to decide
The blind hole press rivet nut column is installed on the thin plate:In the use of riveted bolts in installation and method and principle have been identified, but the riveted bolts still need special riveting equipment to operate, which guarantees the performance of essential factor riveted bolts can keep stable after installation in the. When installing, press the head of the riveting press and the pressure stud to balance vertically, and press down evenly.Rivet nut column and riveted bolts or nuts column, is a fastener used in sheet metal, sheet metal, chassis, cabinet, rivet nut column and its shape is hexagonal, the other end is cylindrical, the middle of the six corners with a cylindrical recess, its shape is internal thread holes through the press six preset angle head into the sheet inside (aperture preset holes are slightly larger than the outer diameter of cylindrical pressure rivet studs) around the hole to produce plastic deformation, the deformation part is squeezed into the slot standoffs in the rivet nut column riveting in thin plate thus, the effective fixed threaded on the sheet.
Because the strength of the aluminum profile is too small, it is not suitable for thread matching. It is necessary to use screw sleeve (or wire screw sleeve) to form internal thread, or to solve the problem of strength with rivet nut;If it is for the wall thickness, is used for riveting nuts with the tool is riveter, or the number of small batch, with a large amount of manual, can use pneumatic riveter considering.
