High-molecular material multi-functional fatigue durability testing machine

Abstract

The invention discloses a high-molecular material multi-functional fatigue durability testing machine. The high-molecular material multi-functional fatigue durability testing machine comprises a tankbody; a separating plate is arranged in the tank body at the middle part of the tank body; two motor box sets are symmetrically arranged on the two sides of the tank body; servo motor decelerators arearranged on the sides of the internal part of the tank body close to the motor box sets; servo motors are arranged at the middle parts of the internal parts of the motor boxes; one side of each motorbox close to the corresponding servo motor is connected with a motor tank cover through inside hexagonal bolts; the upper side of the internal part of the tank body is provided with an ultrasonic flaw detector; a PLC controller is used to control opening of a U-shaped clamping plate connected with a first electric telescopic rod through telescopic connection to move, so that it is convenient forstretching and compression tests of high molecular materials; a transparent plate is arranged at the internal middle part of a sliding door, and the upper side of the internal part of the tank body isprovided with a LED illuminating lamp, so that it is convenient for observation of test personnel on test process; an electromagnetic heater is combined with a temperature sensor to stimulate the working temperature environment of the high molecular materials.

Description

technical field [0001] The invention relates to the technical field of fatigue durability testing machines, in particular to a polymer material multi-capacity fatigue durability testing machine. Background technique [0002] Polymer materials are materials composed of compounds with relatively high molecular weights, including rubber, plastics, fibers, coatings, adhesives, and polymer-based composite materials. Generally, the traditional fatigue durability test method for polymer materials includes two steps. One is to use Ordinary fatigue durability testing machine for fatigue durability test, the second is to carry out dimensional detection and mechanical performance detection after the test, these two steps can only get the change of sample performance before and after the sample test, can not determine the change start time of the sample and The moment when the change is most obvious leads to inaccurate test data and cumbersome test operations. For example, the patent ap...

[0002] Polymer materials are materials composed of compounds with relatively high molecular weights, including rubber, plastics, fibers, coatings, adhesives, and polymer-based composite materials. Generally, the traditional fatigue durability test method for polymer materials includes two steps. One is to use Ordinary fatigue durability testing machine for fatigue durability test, the second is to carry out dimensional detection and mechanical performance detection after the test, these two steps can only get the change of sample performance before and after the sample test, can not determine the change start time of the sample and The moment when the change is most obvious leads to inaccurate test data and cumbersome test operations. For example, the patent application publication number 201620422679.8 discloses a multi-capacity fatigue durability tester for polymer materials. Pneumatic pressure applying device located above the sample placement table, the pneumatic pressure application device is installed on the supporting frame, including the pressure applying cylinder and the pressure plate installed at the end of the piston rod of the pressure applying cylinder, and the left and right sides of the sample placing table are respectively installed with The left column and the right column are respectively equipped with a displacement sensor and a pressure sensor, and the displacement sensor is electrically connected to the displacement recording module in the host, but the above patents have a single function during use and cannot The tensile, compression, torsion and pressure tests of polymer materials are not convenient for testers to observe the test process, and it is impossible to simulate the working temperature environment of polymer materials for testing, and the test effect is not good
