Service HotlineTherefore, how to provide a socket nut, a fastener and an installation method thereof that are more firmly connected and can be applied to thin-walled profiles is a technical problem to be solved by those skilled in the art.
Basic requirements for the installation of T-bolt sleeve components: only when the T-head and the middle slot of the anchoring plate are in good agreement and the anchoring surfaces are in close contact, can the force be evenly applied. If the T-head and the anchoring plate are in line contact, even only point contact , the bolt is partially stressed, which will seriously affect the life. Therefore, the verticality of the sleeve installation must be less than or equal to 1/1000, that is, the horizontality of the anchoring plate surface must be less than or equal to 1/1000, and the center deviation of the sleeve must be controlled within 5mm (the center deviation of the T-bolt is 2mm). Therefore, improving the embedded accuracy of the T-bolt sleeve is the key to the installation of the T-bolt integral sleeve.
Portlandsquare nut described by Guangdong Yueluo Hardware Industry Co., Ltd. includes a nut body 1, the nut body 1 is in the shape of a cube, the side length is 7.6mm, and the height is 2.4mm. The upper and lower ends of the nut body 1 are respectively set. There are circular protrusions 2 and circular protrusions 3 with a height of 0.25mm, and the circular protrusions 2 and the circular protrusions 3 are respectively tangent to the upper and lower surfaces of the nut body 1 in a square shape. A through hole 4 is provided in the middle of the shaped protrusion 2 and the circular protrusion 3, and runs through the nut body 1. The opening of the through hole 1 is provided with a chamfer 5 of 30°, and a thread 6 is provided on the inner wall of the through hole 4. , the circular protrusion 2 is provided with a number of strip-shaped protrusions 7 along the circumference inward to the opening of the through hole 4. The number of the strip-shaped protrusions 7 can be arbitrary, and the ideal number is 26, and the through hole 4 is open. There are several strip-shaped grooves 8 at the circumference of the circular protrusion 3. The number of strip-shaped grooves 8 can be arbitrary, and the ideal number is 26. The circular protrusions 2 and the circular protrusions 3 There is a chamfer 9 of 15° extending outward to the prism of the nut body 1 . The production of Portlandsquare nuts described by Guangdong Yueluo Hardware Industry Co., Ltd. is basically the same as the traditional nut process. The key point is to use a punching machine to punch out circular protrusions on both ends. High, and the circular protrusion 2 is punched again to make a bar-shaped protrusion 7, and at this time, the height of the circular protrusion 2 is consistent with the plane height of the circular protrusion 3, and the circular protrusion 3 is formed by stamping. groove 8. The contact surface of the nut body 1 is increased by providing circular protrusions 2 and circular protrusions 3 on the upper and lower end surfaces of the nut body 1, and respectively providing a bar-shaped protrusion 7 and a bar-shaped groove 8 at the two circular protrusions. Therefore, the friction between the nut body 1 and the fastener is effectively increased, and a good fastening effect is achieved.
The composition and proportion of this high-performance Portlandstainless steel screw thread are: 0.08%-0.15% C; 0.01%-0.60% Si; 0.02%-0.60% Mn; 0.01%-0.03% P; 0.002%- 0.03% S; 12%-14% Cr; 0.8%-1.5% Mo and the rest is Fe. The preparation method includes the following steps: smelting molten steel according to chemical composition requirements; hot rolling; annealing and pickling to obtain a stainless steel plate blank; coating and drying; cold drawing; cleaning and drying with a neutral activator; quenching; tempering ; coated and dried; drawn into stainless steel thread. This high-performance Portlandstainless steel screw line is energy-saving and environmentally friendly, with high corrosion resistance, high elasticity and high toughness. The preparation method and process are advanced and simple, and the production cost is low.
Rivet nuts, pull caps, and instant pull caps are widely used in the assembly of electromechanical and light industrial products such as automobiles, aviation, instruments, furniture, and decoration.
