le ressort industriel fasteners Germany le ressort industriel model le ressort industriel price

le ressort industriel fasteners are a type of fastener consisting of a head and a shank, used to tightly connect two parts (or components) with holes, making them into a single unit. This type of connection is called rivet connection, or riveting for short. It belongs to non-detachable connections. In riveting, the parts to be riveted are connected by utilizing their own deformation or interference fit. There are many types of rivets, and they are not limited to specific forms. Rivets are usually applied to the connection and riveting between objects, and usually require the use of specific special tools for operation. Rivets are divided into many types, such as semi-round head rivets, flat cone head rivets, countersunk head rivets, semi-countersunk head rivets, flat head rivets, hollow rivets, tubular rivets, nameplate rivets, etc., to meet different operational needs. They are mainly used for riveting various thin structural parts in industries such as vehicles, ships, construction, machinery, and electronics.

le ressort industriel fasteners history

The earliest metal deformation bodies were likely the ancestors of what we now know as rivets. For example, after successfully casting large bronze statues during the Bronze Age, Egyptians and Greeks used rivets to join the components together. In 1916, when H V White of the British Aircraft Manufacturing Company first obtained a patent for blind rivets capable of single-sided riveting, few people anticipated that such rivets would be applied so widely. From aerospace to office machines, electronic products, and sports field equipment, it can be said that these blind rivets have now become an effective and secure method of mechanical connection. Hollow rivets were invented for equipment assembly; although the exact time of their invention is not entirely clear, harnesses were invented between the 9th and 19th centuries AD. Riveted harnesses, like horseshoes with nails, liberated slaves from heavy labor. Rivets also spurred many important inventions, such as iron tongs used by coppersmiths and blacksmiths, and shears for shearing sheep wool.

le ressort industriel fasteners introduction

Common types include R type rivets, fan rivets, blind rivets (break-stem rivets), tree-shaped rivets, semi-round head, flat head, semi-hollow rivets, solid rivets, countersunk head rivets, blind rivets, and hollow rivets. These typically rely on their own deformation to connect the riveted parts. Cold riveting is generally used for sizes smaller than 17 mm, while hot riveting is used for sizes larger than this. However, there are exceptions; for instance, nameplates on certain locks are riveted using the interference fit between the rivet and the lock body hole. R type plastic rivets, also known as expansion rivets, consist of two parts: a plastic male pin and a female clip. They do not require installation tools; place the mounting base into a smooth hole, then press down on the head. The specially designed legs expand under force, locking firmly onto the mounting surface. They are commonly used to connect plastic housings, lightweight sheets, insulating materials, circuit boards, or any other thin, lightweight materials, offering an aesthetic, practical, and easy-to-use solution.

le ressort industriel fasteners standards

Standards for rivet product dimensions: specifically stipulate content regarding basic product dimensions; for products with rivets, this also includes basic rivet dimensions, rivet closing, shoulder distance, undercut and chamfer, and end dimensions of external rivet parts. Standards for technical conditions of fastener rivet products. Mainly include standards and corresponding specific regulations regarding product tolerances, mechanical properties, surface defects, surface treatment, and product testing. Standards for rivet product acceptance inspection, marking, and packaging: specifically stipulate content regarding acceptable quality levels and sampling plans for spot checks during factory acceptance, as well as product marking methods and packaging requirements. Standards for marking methods of standard parts, fasteners, rivets, bolts, and screws: specifically stipulate content regarding complete marking methods and simplified marking methods for products. Other standards for rivets: such as standards for fastener terminology, standards for fastener product weight, etc.
