Description

Technical Field

[0001] This utility model relates to the field of automotive sealing ring technology, specifically to an automotive sealing ring tensile testing device. Background Technology

[0002] Automotive seals are sealing components used in automobiles, primarily made of elastomers such as rubber. They function as seals in various parts of the vehicle to prevent leakage or intrusion of liquids, gases, or solid substances. Types of automotive seals include O-rings, Y-rings, U-rings, and V-rings, each with specific applications and functions. For example, O-rings are mainly used for static sealing, Y-rings for dynamic sealing, U-rings for sealing linear motion, and V-rings are primarily used for sealing hydraulic systems, offering excellent sealing performance and load-bearing capacity. Maintaining and replacing automotive seals is a crucial part of vehicle maintenance. For instance, regularly replacing seals can significantly restore vehicle performance and reduce problems like oil leaks. Furthermore, proper installation and use of seals are essential for ensuring normal vehicle operation and extending equipment lifespan. Seal tensile strength refers to the seal's ability to withstand tensile forces. As a vital sealing element, seals are widely used in various mechanical equipment and industrial fields; their tensile strength directly affects sealing effectiveness and service life. Therefore, it is essential to study and test the tensile properties of sealing rings. Tensile strength is one of the important properties of sealing rings, playing a crucial role in ensuring sealing effectiveness and service life. Through proper material selection, structural design, and installation, the tensile properties of sealing rings can be improved, thereby better meeting the sealing requirements of various industrial sectors.

This automotive seal ring tensile testing device has a simple overall structure, achieves good clamping effect, and ensures the effectiveness of the device in testing the tensile strength of automotive seal rings.

[0004] The above applications currently have the following shortcomings:

[0005] When the existing device performs a tensile test, the sealing ring will rub against the tension hook, causing wear on the inner wall of the sealing ring.

[0006] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a tensile testing device for automotive seals in order to achieve a more practical purpose. Utility Model Content

There are two material boxes 7, and the number of positioning suction cups 17 is the same as the number of material boxes 7. The hydraulic cylinder 4 drives the pull hook 1 6 to move horizontally, and adjusts the distance between pull hook 1 6 and pull hook 2 9, so that the tension test of the sealing ring can be performed. At the same time, the pull hook 1 6 and pull hook 2 9 contain rubber pads 15, which can buffer the friction between the sealing ring and pull hook 1 6 and pull hook 2 9, and avoid damage to the inner side of the sealing ring.
