Clinching stud Introduction
Time：2015-05-21 22:36:57Click rate：
Riveting nut column, also known as riveted stud or nut column, is a fastener used in sheet metal, sheet metal, chassis, rack, rivet nut column its hexagonal shape at one end and the other end is cylindrical, hexagonal edge and a cylindrical middle of a undercut, the inner shape of the internal thread, through the press head pressed into the hex hole sheet preset (preset hole diameter is generally slightly larger than the outer diameter of the cylindrical stud riveted) make surrounding the hole plastically deformable portion is extruded rivet nut column retraction groove, so pressure riveting nut column clench on the sheet to form the sheet at the effective fixed internal thread.

What is the pressure riveting nut column?
Pressure riveting nut column from the material and internal thread form into cutting steel rivet nut through-hole SO-type column, stainless steel rivet nut through-hole column SOS type, fast cutting steel blind rivet nuts and stainless steel blind BSO column hole pressure riveting nut column BSOS four kinds, respectively applied to different environments.
Pressure riveting nut column is no specific national standards, the early manufacturers from the United States, and gradually formed today's industry standard was introduced after the country. Mostly from domestic producers in Dongguan, Suzhou, Jiangsu and Guangdong and other regions.
2 Installation
In clinching stud of use, installation and the methods and principles have been identified, although, but clinching stud riveting pressure or require dedicated equipment to operate, which is to ensure the clinching stud after the installation is complete, you can maintain a stable job Performance indispensable factor. When you install should remain riveted head riveting press and vertical stud balance, even under pressure.
3 standard shape
This general there are two, one is through-hole riveted stud, the other is a blind hole riveted stud, the main difference between them is that the stud in the hole is not pass, the pass, then, is pass well, not through words is a blind hole. This is mainly to see how customers are using, mainly to see the performance and accessories meet the requirements of the decision. One thing to note is that if it is too long stud, pass through holes in general is not very good, not very good production. So a little longer studs blind hole riveted stud more. Materials for the production of riveted studs are carbon steel, carbon steel, stainless steel. Use steel or carbon steel production pressure riveting nut column to heat treatment and surface zinc or nickel.
4 Production
Production clinching stud equipment for Taiwan's precision automatic lathe, the spindle is equipped with five sets of tools, equipped with fine adjustment screw, drilling, tapping, milling, chamfering at the same time once processing is complete, accurate concentricity, smooth surface no tools traces.
5 Use
Pressure riveting nut riveting pressure column can be mounted on 0.5mm thick sheet, after riveting pressure can be formed on top of a solid inner thread. Riveting device using parallel down into the head, use the hex clinching stud and sheet metal edge bite, prevent sliding and falling.
6 Industry Standards
Clinching stud shape from the outside view is riveted standard internally threaded fasteners. Riveted screw screwed into the direction of the direction of such exposed fasteners. Its types: ground stud; countersunk stud; rose riveting stud; extrusion stud, reaming stud, stud, stud general categories. Here to talk in detail about the differences between various types of pressure riveting stud.
In addition to defining the studs and nuts to distinguish between working conditions, but also from the Model division: Stud length code after the code represents riveted exposed length portion of said length and nut pushed portion.
First, countersunk riveted stud --CSS-632-3 ﹑ CSOS-M4-6
CSS is 12-gon head, CSSOS was hexagonal head. Materials are all SUS. Countersunk riveted studs used on thick material, CSOS a minimum thickness of 2.4, CSS, compared with 1.6. Therefore such rivets rarely used. For the length of the code is 1/16 inch, instead of 1/32.
Second, rose riveting round stud --KFB3-440-2 type ﹑ KFB3-632-24
Such as flange type riveted stud, commonly used in PC board, its length code is also L / 32 L inches or millimeters. This class is also suitable for thick material stud (1.27 to 1.65).
Third, grounding type riveted stud --SOSG-6440-6 ﹑ ﹑ SOAG-3.5M3-8 SOSG-8632-10 (over)
SOxG class stud is no longer in front of their code by adding class B to represent blind hole, but longer (greater than 12 mm) made of blind holes on the class. Its pre-punched aperture with first class ordinary studs, the length of the code is also L / 32 L inches or millimeters. Minimum class stud riveted sheet thickness of 1.0 mm. This class has a reamer head stud-like tines, dedicated to connect the PC board.
Fourth, the stud in the connector industry, also used in the following stud --DSOS-440-275 ﹑ DSO-M3. Class stud screws at both ends to be connected, only two thread size. DSOS stainless steel material, it is relatively common; DSO was generally carbon steel, less commonly used.
Clinching stud generally use relatively wide range, there are many places have used. For example, the sheet metal industry, riveted to a metal plate. For example, there used chassis cabinets above many. Of course, some of the above electronic products, electrical products, mechanical products, etc. can also be useful to.
