Introduktion af 12 kategorier af rustfri stålbefæstelser
Befæstelseselementer i rustfrit stål, også kendt som standarddele på markedet, er en generel betegnelse for en type mekaniske dele, der bruges til at fastgøre og forbinde to eller flere dele (eller komponenter) til en helhed. Befæstelser i rustfrit stål omfatter 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. Møtrik: med indvendige gevindhuller er formen generelt flad sekskantet cylindrisk form, men også flad firkantet cylindrisk form eller flad cylindrisk form, med bolte, tappe eller maskinskruer, der bruges til at fastgøre og forbinde to dele, så de bliver 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. Træskrue: Det ligner også maskinskrue, men gevindet på skruen er en speciel ribbe til træskrue, som kan skrues direkte ind i trækomponenten (eller delen), der bruges til at forbinde et metal (eller ikke{ {1}}metal) med et gennemgående hul. Delene er fastgjort sammen med et træelement. Denne forbindelse er også en aftagelig forbindelse.
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. Samling og forbindelsespar: samling refererer til en type rustfri stålmøtrik, der leveres i kombination, såsom en kombination af en bestemt maskinskrue (eller bolt, selv-leveret skrue) og en flad skive (eller fjederskive) , låseskive); Tilslutning Hjælpe refererer til en type rustfri stålfastgørelsesanordninger, der leveres af en kombination af specielle bolte, møtrikker og spændeskiver, såsom høj-sekskantbolte til stålkonstruktioner.
