Rivets are parts of riveted parts that are connected by self-deformation or interference in riveting. There are many kinds of rivets, and they are informal. Commonly used are half round head, flat head, countersunk head rivets, pull core rivets, hollow rivets, which are usually connected by their own deformation. There are many kinds of rivet countersunk rivet, tubular rivets, flat cone head rivet, flat head rivets, round head rivet, rivet, without a large oval head rivet, oval head rivet, flat head rivets, flat, cylinder head and a half, yellow rivet, flat head rivets, hollow rivet round head rivet, core rivet, cone core rivet, rivet, rivet, hollow rivets, sign rivets, half countersunk rivet, countersunk head Rivet, tubular rivet, flat cone head rivet, flat head rivet, half round head rivet, headless rivet, large flat head rivet, flat head rivet, flat head rivet, etc., regional restrictions have also produced many local names, but in the specification, should be specified in detail: Head shape diameter * Head thickness * Pipe diameter * length (excluding head thickness) * aperture * hole depth, usually, the aperture and depth of the standard can be omitted, if you do not have drawings or pictures, you should include these elements, and then inform the material, basically can directly production.
Hollow rivet is usually used in clothing, footwear and other industries, solid need to riveting, used in heavy industry connection, often is not detachable structure, the most widely used half a hollow rivet, beam mouth (wire diameter the smaller) nail use hard wire manufacturing, can need not pre hole through the 0.5 mm thickness of steel plate, the rivet cannot bending deformation, are widely used in the password boxes, Suitcases and military cases above, hollow nails (semi-hollow rivets) are made of soft wire, generally require riveting can not crack after opening, there are many types, at present, some toys above the shaft has begun to use a large area of semi-hollow nails or child mother nails instead, can greatly reduce production costs. Core-pulling and core-breaking rivets are mostly used for riveting of relatively thin soft materials. The general requirements are not strict, and the manufacturing materials are usually produced with materials with good plasticity.
Half round head rivet is mainly used for riveting with large transverse load, the most widely used. Flat conical head rivet due to nail head mast, corrosion resistance, often used in ship hull, boiler water tank and other strong corrosion riveting occasions.
Countersunk head rivet is mainly used for riveting occasions where the surface must be smooth and the load is not large. Semi - countersunk head rivet is mainly used in the riveting occasions where the surface must be smooth and the load is not large.
Flat head, flat head rivet is mainly used for metal sheet or leather, canvas, wood and other non-metallic materials riveting occasions.
Large flat head rivets are mainly used for riveting of non-metallic materials. Semi - hollow rivets are mainly used for riveting occasions with small load.
Headless rivets are mainly used for riveting of non-metallic materials.
Hollow rivets are light in weight and weak in head, used for riveting non-metallic materials with small load. Tubular rivets are used in non - metallic materials for non - mechanical riveting.
Sign rivets are mainly used for riveting machines, equipment and other above the nameplate.
Pull core rivet is a kind of single-side riveting rivets, but must use special tools - riveting gun (manual, electric, moving) for riveting. This KIND OF RIVET APPLIES TO INCONVENIENCE ESPECIALLY TO USE COMMON RIVET (MUST UNDERTAKE RIVETING TO JOIN FROM BOTH SIDES) RIVETING OCCASION, REASON IS USED WIDELY AT THE PRODUCT SUCH AS BUILDING, AUTOMOBILE, SHIP, AIRCRAFT, MACHINE, ELECTRIC APPLIANCE, FURNITURE. Among them, the open-mouth oblate head core pulling rivet is the most widely used, countersunk head core pulling rivet is suitable for the performance of the need for smooth riveting occasions, closed type core pulling rivet is suitable for the requirements with higher load and a certain sealing performance of the riveting occasions.
Hit core rivet is the rivet of another kind of one-sided riveting, when riveting, with hand hammer knock rivet head shows nail core, make it and nail head end face are flush, complete riveting operation namely, very convenient, especially apply to inconvenient use common rivet (must undertake riveting from both sides) or pull core rivet (lack pull riveting gun) riveting occasion. Flat head core rivet is usually used, countersunk head core rivet is suitable for smooth surface riveting.
