Introduksjon av 12 kategorier av festemidler i rustfritt stål
Festemidler i rustfritt stål, også kjent som standarddeler på markedet, er en generell betegnelse for en type mekaniske deler som brukes til å feste og koble to eller flere deler (eller komponenter) til en helhet. Festemidler i rustfritt stål inkluderer 12 kategorier:
1. Rivet: It consists of two parts: a rivet shell and a rod, which are used to fasten and connect two plates with through holes to achieve the effect of becoming a whole. This form of connection is called rivet connection, or riveting for short. Riveting is a non-removable connection because the rivets on the parts must be broken in order to separate the two parts that are connected together.
2. Bolt: A type of stainless steel fastener consisting of a head and a screw (a cylinder with an external thread), which needs to be matched with a nut to fasten and connect two parts with through holes. This form of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
3. Stud: a type of stainless steel fastener without a head, only with external threads on both ends. When connecting, one end of it must be screwed into the part with the internal threaded hole, the other end must pass through the part with the through hole, and then screw the nut, even if the two parts are tightly connected as a whole. This form of connection is called a stud connection, which is also a detachable connection. It is mainly used for occasions where one of the connected parts is thick, requires a compact structure, or is not suitable for bolt connection due to frequent disassembly.
4. Mutter: med innvendige gjengede hull er formen generelt flat sekskantet sylindrisk form, men også flat firkantet sylindrisk form eller flat sylindrisk form, med bolter, bolter eller maskinskruer, som brukes til å feste og koble sammen to deler, slik at de blir en hel.
5. Screw: It is also a type of stainless steel fastener composed of two parts: head and screw. It can be divided into three categories according to the purpose: machine screw, set screw and special purpose screw. Machine screws are mainly used for a fastened connection between a part with a fixed threaded hole and a part with a through hole, without the need for nut matching (this connection form is called screw connection, which is also a detachable connection; it can also be Cooperate with the nut, it is used for the fast connection between two parts with through holes.) The set screw is mainly used to fix the relative position between the two parts. Special purpose screws, such as eyebolts, are used for hoisting parts.
6. Self-tapping screw: similar to machine screw, but the thread on the screw is a special thread for self-tapping screw. It is used to fasten and connect two thin metal components to make them a whole. Small holes need to be made in advance on the components. Due to the high hardness of this kind of screw, it can be directly screwed into the hole of the component, so that the Forms a responsive internal thread. This form of connection is also a detachable connection. 7. Welding nails: Due to the dissimilar stainless steel nut composed of light energy and nail head (or no nail head), it is fixed and connected to a part (or component) by welding so as to be connected with other parts.
8. Treskrue: Den ligner også på maskinskrue, men gjengen på skruen er en spesiell ribbe for treskrue, som kan skrus direkte inn i trekomponenten (eller delen), som brukes til å koble til et metall (eller ikke{ {1}}metall) med et gjennomgående hull. Delene er festet sammen med et treelement. Denne tilkoblingen er også en avtakbar tilkobling.
9. Washers: a type of stainless steel fasteners in the shape of an oblate ring. It is placed between the supporting surface of the bolt, screw or nut and the surface of the connecting part, which increases the contact surface area of the connected parts, reduces the pressure per unit area and protects the surface of the connected parts from damage; another type of elastic washer, It can also play a role in preventing the nut from loosening.
10. Retaining ring: It is installed in the shaft groove or hole groove of the machine and equipment, and plays the role of preventing the left and right movement of the parts on the shaft or on the hole.
11. Pins: mainly used for parts positioning, and some can also be used for parts connection, fixing parts, transmitting power or locking other stainless steel standard parts.
12. Montering og koblingspar: montering refererer til en type rustfri stålmutter som leveres i kombinasjon, for eksempel en kombinasjon av en bestemt maskinskrue (eller bolt, selv-levert skrue) og en flat skive (eller fjærskive) , låseskive); tilkobling Auxiliary refererer til en type festemidler i rustfritt stål som leveres av en kombinasjon av spesielle bolter, muttere og skiver, for eksempel høy-sekskantbolter for stålkonstruksjoner.
