Waterproof stud type B seal nut column BS stainless steel sealing nut colur
Auther Pubdate2018-09-17
B/BS type seal stud schedule of standards and specifications
The sealing nut column
Applied to need to be closed at the bottom of the working environment, sometimes also called waterproof stud or nut column
Sealing nut column was divided into B and BS, type B for carbon carbon, BS for stainless steel
Specific material for: B - 1214 or 1215, BS - SUS303
Hardness: B type seal stud of carburizing to HV400-500
BS sealed stainless steel stud makes no heat treatment, so it is original hardness of stainless steel rod, namely HRB90 (HV200)
Surface treatment: B - the default is blue white zinc, BS - the default is stainless steel
Stainless steel sealing nut column
BS stainless steel sealing nut column material;SUS303 left specifications: BS - M4-2
Stainless steel sealing nut column using SUS303 production, due to rust in the workplace, such as aluminum copper seal waterproof effect, not recommended for stainless steel plate (though can also be used)
Sealing pressure riveting nut has a blind hole of internal threads, the head end is similar to S type pressure riveting nut, pressure riveting on the plate to form an effective internal thread.
Using automatic lathe production, by the bar a turning to punch, embossing and tapping.

Type B seal stud installation method, note what matters and their installation schematic diagram
 

1, sealed stud installation method as left, its installation method of video clear expression.

2, sealed stud installation method is a combination of pressure and pressure riveting nut installed rivet stud installation characteristics of the two, and installed more simple.What is the characteristics of both?Please see the following two links
This is:Pressure riveting nut installation method
This is:Pressure riveting stud installation method


3, the requirement for sheet:
Carbon steel thin plate hardness is not more than HRB70, although we product hardness of HV400 described above, but this is the surface hardness, so the sheet do not heat treatment
Stainless steel plate hardness is not more than HRV80

4, sealed screw and plate material of adaptation
Type B corresponding carbon steel sheet
BS corresponding aluminum or copper - yes, BS is not suitable for pressing of stainless steel plate

5, in the left does not mean punch press punch punch, but pressure riveting machine can punch, implying the problem
- what was the pressure riveting machine?Please refer to thePressure riveting nut with what equipment?

6, left the tooling need user to do, its design is more simple, tooling fixture holes do?- refer to the above specifications in the table size of "B", not "B" in small sizes
