An integrated rubber product testing device for compressive and tensile testing

Abstract

The invention discloses an integrated rubber product testing device for compressive and tensile testing. On the opposite side walls of the mounting plate, the pressure sensor 1 and the ejector rod assembly are respectively arranged side by side in sequence, and on the opposite side wall of the L-shaped mounting plate, the stop rod of the sleeve socket connecting rod assembly is set by using the fixing block, and the stop rod passes through The fixed collar, the limit groove, the rotor, the connecting plate, the suspender and the connecting bar are threaded to connect the threaded screw, and the screw is fixedly connected with the output end of the forward and reverse motor, and the rubber sealing ring is inserted into the push rod assembly. On the inner wall of the U-shaped limiting plate, the motor drives the screw to rotate and move down the fixed collar, so that the L-shaped mounting plate moves to both ends of the chute, and the rubber sealing ring is inserted into the U-shaped limiting plate, so that the ejector rod body is pushed up. The pressure sensor detects the karaage strength of the rubber sealing ring, which effectively prevents the risk of its stretching, deformation, slipping, flying and hurting people.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to an integrated rubber product testing device for compressive and tensile testing. Background technique [0002] Rubber (Rubber) refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer, its glass transition temperature (Tg) is low, and its molecular weight is often large, greater than hundreds of thousands. Rubber is divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life. The rubber sealing ring is a common cont...

Problems solved by technology

[0003] However, the existing rubber product testing equipment can only test a single performance of the rubber sealing ring at a time. After one test is completed, the testing equipment needs to be replaced to perform another performance testing operation on the rubber sealing ring, which is cumbersome to use. It takes a long time; and when the existing rubber product testing equipment performs tensile testing on the rubber sealing ring, once the production quality of the rubber sealing ring is not up to standard, it is easy to break when performing tensile testing on it, and the broken rubber sealing ring It is easy to fly out and hurt people, which has certain safety hazards
