With the trend of automobile and social development, more and more aluminum is used in automobiles (cast aluminum, sheet, profile), which brings huge advantages in light weight and fuel economy. For profiles, because they can only operate unilaterally, correspondingly Brought a certain degree of difficulty, today to talk about the role and characteristics of the internal threaded sleeve on the profile.
Internal thread aluminum sleeve features
a. High-strength internally-threaded aluminum sleeve, especially suitable for the application of high-strength nuts in aluminum profiles. The sleeve is connected to the two end faces of the profile by means of cold connection, so that the two end faces of the profile bear the load together and play the role of the profile reinforcement.
b. The sleeve material is 7-series special aluminum material, and the profile does not produce potential corrosion; the sleeve itself does not have corrosion resistance, but it can be corrosion-resistant by electrophoresis or anodizing.
c. The internal thread has high strength. Based on twice the thread length, the load can meet the stress requirements of pc10.
d. High tightening torque to meet the tightening torque requirements of pc10.9 bolts.
e. Nut range: M6-M14, and seat belt 7/16 inch thread.
f. Mounting holes are simple.

Working process: for one direct pressing and riveting, the two sides of the sleeve and the profile are riveted, and the parts need to be opened in advance. The cooperation between the threaded sleeve and the plate is based on the principle of interference fit, using a punching machine or a riveting machine. Realize the riveting.
Intensity range 480-520
The length range is 12-70mm. Due to the cost problem, there is no special long sleeve, and the production equipment is a five-axis CNC.
Material is 7050
Installation space requirement is 2 sides
Basic parameters
The basic parameters of a generation of standard aluminum sleeves are as follows:
The basic parameters of the first generation of reinforced aluminum sleeves are as follows:
application:
The internal threaded sleeve has been well verified in the application of small ants, which realizes the reinforcement of the profile and provides the function of the installation point. When the upper plate is connected, the aluminum profile is easily crushed, and a threaded sleeve is needed at this time.
Because the direct potential difference between steel and aluminum is easy to cause corrosion, the sleeve of the profile is generally made of 7-series aluminum sleeve, and the welding between the aluminum thread sleeve and the aluminum profile is not conducive to quality control.
