U-bolt, that is, riding bolt, the English name of the riding bolt is U-bolt, it is a non-standard part, the shape is U-shaped, so it is also called U-bolt, the two ends are threaded and can be combined with the nut, mainly used for fixing tubular objects such as water pipes. Or a sheet, such as a leaf spring of an automobile, is called a riding bolt because it fixes the object like a person riding on the horse.
Introduction: U type is generally used in trucks, it is used to stabilize car sites and frames. For example, leaf springs are u-bolts for connection. U-bolts are widely used, mainly for construction installation, mechanical parts connection, vehicle ships, bridge tunnel railways, etc. Main shapes: semi-circular, square right angle, triangle, oblique triangle, etc.
1. Material properties Density, flexural strength, impact toughness, compressive strength, modulus of elasticity, tensile strength, temperature resistance, and color are determined according to the use environment.
2, the material commonly used are carbon steel Q235A Q345B alloy steel stainless steel and so on. Among them, stainless steel has 201 304, 321, 304L, 316, 316L.
3, the national standard for u-bolt: JB/ZQ4321-1997
Standard installation method for u-bolts:
The u-type pipe card installation step method is as follows: providing a u-shaped claw, the claw is provided with four claws; providing two u-shaped bayonet; providing a weight; providing four u-shaped brackets; The claw is molded by plastic material; when assembling, the u-shaped bayonet is attached to the u-shaped claw, and the four u-shaped brackets are respectively fixed to the solid-shaped u-shaped claw And affixing the u-shaped bracket to the weight; using the u-shaped jaw to clamp the u-shaped bayonet and the weight, and then the u-shaped by welding The bayonet is fixed to the weight. The u-type claw tooling device obtained by the invention has simple processing, low cost, and does not affect the assembly of the production line with the fluctuation of the size of the components, and can better meet the welding assembly requirements.
