Problems solved by technology

This structure has the following disadvantages: the device can only be applied to bellows with a diameter of 5-10cm. For bellows in the chemical industry, the diameter is generally 1m-2m, which is much larger than the bellows used in the reference document. This kind of equipment The bellows in the chemical industry cannot be tested for strength

Abstract

The invention relates to the technical field of manufacturing of corrugated pipes, in particular to a corrugated pipe strength testing system. The corrugated pipe strength testing system comprises a transmission mechanism, a lifting mechanism and a sliding mechanism, wherein the transmission mechanism comprises a motor, a reduction box and a transmission case; the output end of the motor is connected with the input end of the reduction box through a belt; the output end of the reduction box is connected with a transmission wheel in the transmission case through a belt; the transmission wheel is arranged on a rotary shaft; both ends of the rotary shaft are supported on ground through bearing blocks; one end of the rotary shaft is connected with an eccentric wheel; the wheel face of the eccentric wheel is hinged to one end of a connecting rod; the other end of the connecting rod is connected with the lifting mechanism. The corrugated pipe strength testing system has the advantages that the existing corrugated pipe with diameter of 1m to 2m can subject to strength test, the blank in the field is filled, and the working efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of bellows manufacturing, in particular to a bellows strength testing system and a testing method. Background technique [0002] Corrugated pipes mainly include metal corrugated pipes, corrugated expansion joints, corrugated heat exchange tubes, diaphragm capsules and metal hoses. Metal bellows are mainly used to compensate pipeline thermal deformation, shock absorption, and absorb pipeline settlement deformation. It is widely used in petrochemical, instrumentation, aerospace, chemical, electric power, cement, metallurgy and other industries. Corrugated pipes of other materials such as plastic play an irreplaceable role in the fields of medium transmission, power threading, machine tools, and home appliances. At present, the Chinese patent discloses a vacuum cleaner bellows rotating fatigue strength tester, application number 201510626645.0, including a base, an electrical box arranged on one side of the base, a...
