Service HotlineRiveting is the most traditional way of connecting metal parts. It has the advantages of easy operation, high reliability and not easy to deform. It is widely used in the skeleton of outdoor products such as tents and camp beds. Commonly used aluminum alloy rivets use their own deformation or interference to connect the parts of the riveted parts in the riveting process. Due to cost and functional considerations, the rivet and the riveted material are often different, which is easy to occur in outdoor high humidity. Electrochemical corrosion, and the commonly used high-strength thin-walled pipes have a large shear stress on the aluminum alloy rivets at the riveting point. Under the combined action of the above two factors, it is easy to cause deformation or even breakage at the riveting point, which affects the life of outdoor products. A kind of Corrosion and shear resistant aluminium alloy rivets.
In the prior art, there are two ways to feed the screws of the locking screw machine, the air blowing type and the air suction type. The air suction type is suitable for relatively small screws. If the screw size is larger than M2, smaller than M5, and the length-diameter ratio is larger than 1.7, the air-blown screw machine can be selected.
Gaskets are divided into: flat washer - grade C, large washer - grade A and C, extra large washer - grade C, small washer - grade A, flat washer - grade A, flat washer - chamfer type - Grade A, high-strength washers for steel structure, spherical washers, cone washers, square bevel washers for I-beam, square bevel washers for channel steel, standard spring washers, light spring washers, heavy spring washers, internal tooth lock washers , Internal serrated lock washers, external serrated lock washers, external serrated lock washers, single-ear stop washers, double-ear stop washers, outer tongue stop washers and stop washers for round nuts, etc.
Countersunk rivet is a kind of part that uses its own deformation or interference connection to connect and position two objects in riveting. It is widely used in automobiles, vehicles, electromechanical products, aerospace products and other fields. When the countersunk head rivet is used, the head of the rivet sinks into the connected parts in whole or in part. This structure is mostly used for parts that require a smooth and smooth appearance. The standard structure of countersunk head rivets is specified in the national aviation standard, national standard and national standard, and the countersunk head rivets involved in these standards are all standard rotary structures.
Sprinkle the excess flat washer 6 on the positioning plate II3-1 on the flat washer positioning plate 3, and shake the flat washer positioning plate 3 by hand. After a short time, the flat washer 6 will be positioned and arranged on the upper positioning plate II3-1. In the flat washer hole 3-7, since the width of the opening groove 113-32 of the baffle plate II3-3 is smaller than the diameter of the flat washer hole 3-7, and the thickness of the upper positioning plate II3-1 is designed according to the thickness of the flat washer 6, each Only one flat washer 6 can be accommodated in the flat washer holes 3-7 of each upper positioning plate II3-1, and then use a brush to remove the excess flat washer
