Automobile metal bracket strengthening nut plate structure

Abstract

The invention discloses an automobile metal bracket strengthening nut plate structure. The material understanding, the chemical components and the mechanical performance of an automobile metal bracket meet the requirements that a, C is smaller than or equal to 0.10, b, Mn is smaller than or equal to 0.50, c, P is smaller than or equal to 0.025, d, S is smaller than or equal to 0.02 and e, AL is larger than or equal to 0.015 when analyzing is conducted through an optical spectrum analyzer; and a, the yield strength is 180-290 Mpa, b, the tensile strength is 270-400 Mpa, c and the elongation rate is larger than or equal to 34% when testing is conducted through a universal tester. The automobile metal bracket strengthening nut plate structure is characterized in that a main body of an automobile metal bracket strengthening nut plate is a hollow cylinder with a thread; the hollow cylinder with the thread is an internal thread formed by being extruded; and overall metal plate sheets are arranged on the two sides of the main body of the nut plate correspondingly and can be bent into any shapes matched with the shape of the automobile metal bracket.

Description

technical field [0001] The invention relates to the manufacturing technology of automobile metal fittings, in particular to the reinforcement nut plate structure applied to automobile metal brackets. Background technique [0002] With the development of the automobile industry, people have higher and higher requirements for the safety of automobiles. In order to adapt to the development of the times and the needs of consumers, automobile manufacturers around the world are also constantly innovating, not only improving the efficacy and quality of auto parts, but also making various improvements to the safety of auto parts produced. In order to improve the safety of the use of parts and reduce cost savings. [0003] The current automobile metal bracket strengthens the nut plate, and the automobile metal bracket used is made of welding metal nuts on the metal plate. This kind of product will cause the automobile metal bracket to bear the load when the car moves with the change...

AI Technical Summary

Problems solved by technology

[0003] The current automobile metal bracket strengthens the nut plate, and the automobile metal bracket used is made of welding metal nuts on the metal plate. This kind of product will cause the automobile metal bracket to lose its bearing capacity as the environment, temperature and humidity change during automobile movement. Fracture and damage, so there are many deficiencies in this kind of technology and products, especially the safety of the nut plate of the metal bracket of the car will be greatly reduced, and the service life and the strength of the nut will be reduced.
