Description

Technical Field

[0001] The utility model relates to the technical field of sealing gasket detection equipment, in particular to a tensile strength detection device for sealing gasket production. Background Art

[0002] Sealing gaskets are a kind of sealing spare parts used in machinery, equipment, pipelines, and any place where there is fluid. They are used inside and outside to seal. Sealing gaskets are made of metal or non-metallic plate materials through cutting, stamping or cutting processes. They are used for sealing connections between pipelines and between parts of machinery and equipment. They can be divided into metal sealing gaskets and non-metallic sealing gaskets according to the material. Metal gaskets include copper gaskets, stainless steel gaskets, iron gaskets, aluminum gaskets, etc. Non-metallic gaskets include asbestos gaskets, non-asbestos gaskets, paper gaskets, rubber gaskets, etc.

[0003] In the prior art, a Chinese utility model with publication number CN216051108U discloses a tensile strength testing device for sealing gasket production, including a supporting base and a testing component, wherein screws are rotatably mounted at both ends of the supporting base through bearings, and movable pads are threadedly sleeved on the outer sides of the two screws, and the testing component for tensile strength testing of the sealing gasket is mounted on the supporting base and the movable pad.

[0004] In the above technology, the staff puts the sealing gasket to be tested on the outside of the connecting ring, and then drives the motor in the driving member to rotate, driving the driving wheel and the tapered rod to rotate. At the same time, under the action of the transmission belt, the two driven wheels drive the two screws to rotate, thereby driving the movable pad to move downward, so that the detection rod in the detection member contacts the outside of the tapered rod, and moves outward along with the outside of the tapered rod, pushing the contact arc piece outward, thereby realizing the tensile strength test of the sealing gasket. During the test, the sealing gasket must first be put on the connecting ring, but the size of the connecting ring is unchanged and cannot be adjusted according to the size of the sealing gasket. Therefore, the staff needs to take it again and place it on the detection device of the appropriate size, which will waste time and physical strength and affect the detection efficiency.
