Description

Technical Field

[0001] This utility model specifically relates to the field of rubber ring stretching technology, and more specifically to a sealing rubber ring stretching test device. Background Technology

[0002] Tensile testing of sealing rings is an important means of evaluating their mechanical properties and sealing reliability; the tensile testing machine is the main equipment for conducting tensile testing of sealing rings, which can accurately apply tensile force and measure the stress and deformation of the ring during the tensile process;

[0003] After the sealing rings are produced, their appearance, size and performance need to be inspected and tested. Appearance and size can be judged by manual observation, but performance cannot be directly detected. Therefore, it is necessary to use equipment to test the performance of the sealing rings. However, the traditional testing equipment can only test the sealing rings one by one, which makes the work inefficient and cannot effectively meet the production needs.

[0004] A search revealed that Chinese Patent Publication No. CN202222277120.9 discloses a performance testing device for a multi-group stretchable sealing ring; it includes a worktable and a double-headed cylinder. The worktable is fixedly mounted with support legs around its bottom, and a control panel is attached to the right side of the bottom of the worktable. A display panel is fixedly mounted on the right side of the top of the worktable, and a back plate is vertically and crosswise fixedly mounted on the left side of the top of the worktable. A track is fixedly mounted on the top front of the back plate.

[0005] The aforementioned patent describes a method where the sealing ring to be tested is fitted onto the outside of an annular structure composed of four arc-shaped contact surfaces. A telescopic cylinder is used to lift a conical platform within the central hole. The conical platform compresses the inner inclined surface, causing the four internal expansion clamping arms to slide synchronously away from the conical platform within the sliding groove. The internal expansion clamping of the sealing ring is achieved by gradually increasing the diameter of the annular structure composed of the four arc-shaped contact surfaces. While this method can achieve the effect of tensile testing, the end plate limits the maximum sliding stroke of the internal expansion clamping arms within the sliding groove. Therefore, when the tensile strength range of the sealing ring exceeds the range of the internal expansion clamping arms, the device in the aforementioned patent cannot perform accurate testing. Furthermore, the test data of the sealing ring in the aforementioned patent cannot be effectively and intuitively observed during testing; it is necessary to calculate the pressure applied to the telescopic cylinder, which is time-consuming and labor-intensive.

Then, the tensile sensor is moved upward simultaneously by an electric push cylinder and a mounting plate. Each tensile sensor has a corresponding display, so that the tensile value of the sealing ring can be effectively and intuitively observed during the testing of the sealing ring, thereby solving the problems mentioned in the background art.
