Advantages of cold heading
|Speed||Depending upon the size and complexity of the part and the nature of the equipment of producing them, production rates of 4000 pieces per hour can be achieved.|
|Economy||When compared to casting and machining labor the metal savings alone justify the conversion to an impact extrusion.In some cases when the aluminum slug is sized accurately, little or no trimming or other secondary operations are required.|
|Strength||The impact process naturally work hardens non-heat treatable alloys, while the heat treatable alloys can be heat treated in normal fashion after processing.|
|Toughness||The impact extruding process produces parts that are dense and porous-free in structure. This condition cannot be obtained in a casting process or by machining of a bar material.|
|Versatility||After impacting, the product can be treated the same as any other piece of material. Secondary operations such as machining, grinding, welding, bending, plating or anodizing can be performed in the same way as any other piece manufactured by a more conventional process.|
|Consolidation||Impacts can directly replace machined components, or welded or riveted assemblies, in many designs. The process often reduces product costs for secondary machining operations and in many cases increases the strength of a product that was previously an assembly.|
|General knowledge on “rivets” ?|
Rivet is a nail-shaped objects, one end cap: In the riveting, the use of their own strain or interference connections are riveted parts.
Types and Uses:
Commonly used R rivets, fan rivets, blind rivets (Rivets), tree rivets, round head, flat head, empty heart rivets, solid rivets, countersunk head rivets, blind rivets, blind rivet, which usually use deformation connection itself is riveting pieces. Generally less than 8 mm cold riveting, larger than the size of the hot riveting. But there are exceptions, such as some of the locks on the nameplate, is the use of rivets and lock hole interference riveting.
Also known as R-type plastic rivets expansion rivets, nails and female child by plastic buckle two parts. Without the use of their tools during installation, the mounting base is placed in a smooth bore, and then press the head, feet swell after distraction force specially designed to be firmly locked to the mounting surface.
It is used to connect the plastic housing, lightweight sheet metal, insulation materials, circuit boards, or any other thin, lightweight quality materials, beautiful and practical, easy to use.
Fan rivets specifically designed for manual installation, panel or chassis by pulling through the hole into the can, using manufacturing elastomeric material has good toughness, even in the interference fit can be installed quickly. Cleverly designed flexible function with the corresponding aperture slide easily pull into the fan rivet fixed between the main application of electronic computer chassis fan, heat sink and chip purposes, with anti-vibration and reduce noise.
Rivets are very convenient riveting new riveting fasteners, in a relatively small space or no rivet gun or can not use the riveter environment Rivets can exhibit their own unique advantages. Use a hammer hitting nails and other objects on one side of the core can be connected to two or several pieces of riveting success. Rivets in accordance with the shape of the nail cap brim can be divided into oval head and countersunk head Rivets Rivets, according to the combination of different materials can be divided into aluminum Rivets, Rivets aluminum steel, stainless steel strike core rivets, steel steel rivets, aluminum stainless steel rivets, rivets and other plastics. Rivets do not like the same blind rivets must use manual or pneumatic rivet gun riveter to riveting, riveting better and convenience, can be widely used in a variety of connectors riveting.
Plastic rivets tree, also known as inverted tooth plastic rivets are also known as Christmas tree plastic rivets, tooth Chip good elasticity can press fit in a round hole assembly direct manual interference, tooth according to the actual thickness of the flake size adjust itself to fixed, inverted tooth design is firmly fixed after which the rivets installed on the mounting surface is difficult to be pulled out for use between fixed for foam, wood, rubber, automotive interiors and other soft materials. Plastic tree rivet with excellent insulation, fire resistance, non-magnetic, thermal insulation, light weight, high temperature, high strength, corrosion resistance, widely used in various industrial fields.
Rivet types can be divided into open type, closed, double-drum, single drum series, the following is a brief description for each model.
Shen head type blind rivets: requirements for a smooth surface appearance after riveting riveting pieces of riveting.
Double drum type blind rivets: When riveting, the rivet mandrel body-end pull double drum, the two structures to be riveting clamp, and can reduce the effect on the structure of the surface pressure. Uses: mainly used for all kinds of vehicles, ships, construction, machinery, electronics and other industries riveting various thin structures.
Large Head blind rivets: The rivet compared with ordinary blind rivet diameter significantly increased its aluminum cap, when the rivet and rivet connections, with a larger contact area, with more support surface which can enhance the torque strength, can withstand higher radial tension. Applicable industry: for fastening soft, crumbly surface material and large holes, increasing the diameter of the brim soft material for special protection applications.
Closed blind rivets: Designed after riveting mandrel head can wrap design is well suited for many applications have water requirements. With high shear, anti-vibration, anti-hypertension.
Compared with ordinary connector blind rivets, rivet low intensity for a relatively soft material: aluminum rivets, blind rivet the nails are made of high quality aluminum body wire, beautiful and durable riveted never appear after rusting .
Opening stainless steel rivets: The rivet is a high demand pull, the best choice for corrosion resistance.
Round head rivets are mainly used by large lateral loads riveting occasions, the most widely used.
Because of the flat cone head rivets nailhead hypertrophy, resist corrosion, commonly used in the hull, tanks and other strong corrosive boiler riveting occasions.
Flat head rivets
Countersunk head, countersunk head, 1200 countersunk head, countersunk head rivets smooth surface to be mainly used by the load is not riveting occasions.
Flat head rivets used by the general load riveting occasions.
Flat head, oval head rivets or sheet metal is mainly used for leather, canvas, wood and other non-metallic materials riveting occasions.
Large flat head rivets mainly non-metallic materials for riveting occasions.
Semi-tubular rivets are mainly used by the load is not riveting occasions.
Headless rivet mainly for non-metallic materials riveting occasions.
Rivets lightweight, nailhead weak for much of the non-metallic materials under load riveting occasions.
The tubular rivet for non-metallic materials are not load riveting occasions.
Signs rivet riveting machine is mainly used for equipment such as the above nameplate.
It is a kind of blind rivet riveting sided with rivets, but have to use special tools – Riveter (manual, electric, pneumatic) were riveting. Such rivets especially for the inconvenience using conventional rivets (to be riveted from both sides) riveting occasions, it is widely on buildings, cars, ships, aircraft, machinery, appliances, furniture and other products used. Among the open-type oval head blind rivets most widely countersunk head blind rivets suitable for smooth riveting performance need occasions, closed blind rivets with applications that require high loads and has a sealing performance riveting occasions.
Rivets are another class of single caulking rivets, riveting, hand hammer strikes the exposed head of the rivet mandrel, so as to be flush with the end face of the nail head, that is, the caulking operation is completed, very convenient, especially for the inconvenience using conventional rivets (to be carried out from both sides of the riveting) or blind rivets (lack of riveters) riveting occasions. Applications usually oval head hit the core riveting, countersunk head Rivets require a smooth surface suitable for riveting occasion.
But also with some rivets on clothing, become popular elements, mostly on behalf of punk style.
Another rivets on the plug, rather special. Divided into two parts, a thicker section of the capped rod center hole, and another piece hooded finer rod body is an interference fit. When riveting, the thin rod into the thick shaft can be.
Rivet quality detection and checking
Bolt detected ways can be divided into labor detecting and machine automatic detecting. Labor is the most original and most widely used way of coincidence detection. In order to minimize the outflow of defective products, the general production of corporate officers by visual approach to packaging or shipment of product testing to rule out defective products (including bad teeth hurt, mixing, rust, etc.).
Another way for automatic testing machine, mainly magnetic particle inspection.
Magnetic particle testing is the use of the leakage magnetic field interacting with the magnetic particle defects of the bolt, bolt for possible defects (such as cracks, slag, mixing, etc.) differences in permeability and permeability of the steel, after magnetization of these materials are not continuous Kawasaki will occur at magnetic field changes, the magnetic flux leakage portion is formed at the surface of the leakage magnetic field generated in order to attract magnetic particles to form a magnetic powder defect accumulation – magnetic marks, under appropriate lighting conditions, showing the location and shape of the defect, for accumulation of these magnetic powder to be observed and interpreted, has reached the purpose of removing defective products.
