Abstract

The utility model relates to a tester for mainly used for testing vulcanized rubber tensile stress relaxation performance. The tester comprises a frame and a cross beam arranged on the frame and capable of moving up and down; a sensor and an upper clamp holder are respectively connected with the lower part of the cross beam; a lower clamp holder corresponding to the upper clamp holder is arranged on the base of the frame; the upper and the lower clamp holders are arranged in a temperature control box; the upper clamp holder can move up and down in the temperature control box through the cross beam; and a temperature regulation and control device is arranged on the temperature control box. In the utility model, the upper and the lower clamp holders are arranged in the temperature control box, and the temperature regulation and control device is arranged on the temperature control box, so when the temperature regulation is completed, the upper and the lower clamp holders under such temperature environment can improve the measuring accuracy of the testing piece.

Description

New type rubber means of constant strain-tensile test device

Technical field

The utility model relates to a kind of test apparatus of measuring vulcanized rubber tensile stress relaxation performance that is mainly used in, and belongs to the testing machine of rubber and plastic technical field of measurement and test.

Background technology

Rubber means of constant strain-tensile test machine is mainly used in the test of vulcanized rubber ageing properties, is determined at uniform temperature, continuously strain or the intermittently stress relaxation under the strained condition.So how temperature environment is provided, makes it not receive external environment influence just to seem particularly important.

The utility model content

The utility model is to above-mentioned defective, and purpose is to provide a kind of and simulates all temps environment, makes test block such as rubber can under different environment, realize the rubber means of constant strain-tensile test device of testing.

The technical scheme of the utility model employing is for this reason: the utility model comprises frame and is arranged on crossbeam moving up and down on the frame; The crossbeam bottom is connected with sensor and last clamper in turn; The lower gripper that gantry base is provided with and last clamper is corresponding; Said upward clamper, lower gripper are arranged in the temperature-controlled cabinet, and the said clamper of going up moves up and down in temperature-controlled cabinet through crossbeam, and temperature-controlled cabinet is provided with temperature control device.

The utility model has the advantages that: the utility model will be gone up clamper, lower gripper is arranged in the temperature-controlled cabinet; Establish temperature control device on the temperature-controlled cabinet; When temperature transfer establish finish after, last clamper and lower gripper are worked under this temperature environment, the measuring accuracy of raising test block.

Embodiment

The utility model comprises that loading system, control system, measuring system, data handling system, demonstration printing equipment constitute.

Loading system comprises the sample clamp device of being made up of last clamper 9 and lower gripper 11; Last clamper 9 is connected with sensor 6 through connector 7; Set nut is housed on the connector 7 is used for fixing the position of connector 7 on sensor 6, lower gripper 11 is fixed on the base 12.Sensor 6 is fixed on the moving beam 3, and moving beam 3 can move up and down and make rubbery sample be in certain length growth rate state.Last clamper 9 can move up and down in temperature-controlled cabinet 8, and translational speed can be selected.Column 5 is fixed on support 1 and the base 12; Be used for back-up roller ballscrew 2; Servomotor 13 is in transmission connection through belt wheel 14 and ball screw 2, provides moving beam 3 to move required power, and servomotor 13 can be controlled the translational speed and the amount of movement of moving beam 3 accurately.

Strain gauge 10 can be measured the elongation of sample in measuring system, and elongation imports data handling system automatically and handles.Last clamper 9 positions can be located through operating case 4 fast.The upper and lower machine transmits data through serial port, and data function is powerful, can draw real-time curve, and software has overload stoppage protection function.The control system software systems adopt power value, distortion, position closed-loop control and arbitrary curve control (as low-cycle fatigue, three modes switch arbitrarily, step curve control etc.) mode, control accuracy is more accurate.

Data handling system, demonstration printing equipment are handled the signal that each measuring element is measured; Processing through disposal system; Display interface through software shows that in real time the confession operator carries out next step operation; The postposition of line data of going forward side by side is handled, and display device retention time that can will relax shows and reach 30 days that curve a bit shows some time and stress value arbitrarily arbitrarily.

The test procedure of the utility model is:

1) connects main frame and computer power supply, open the Control Software interface, set necessary parameter;

2) before the test temperature-controlled cabinet is preheated the control variation of temperature;

3) under no strained condition; With sample holder on clamper in the preheating 9 and lower gripper 11; Behind certain hour, tensile sample also makes its length growth rate that reaches regulation in official hour, keeps test in the specialized range of stretch value; Stipulate the requirement of data point first, in the measuring process of back, get corresponding stress value of the identical time interval.

Claims

1. rubber means of constant strain-tensile test device; Comprise frame and be arranged on crossbeam moving up and down on the frame, the crossbeam bottom is connected with sensor and last clamper in turn, the lower gripper that gantry base is provided with and last clamper is corresponding; It is characterized in that; Said upward clamper, lower gripper are arranged in the temperature-controlled cabinet, and the said clamper of going up moves up and down in temperature-controlled cabinet through crossbeam, and temperature-controlled cabinet is provided with temperature control device.
