Summary of the invention
The present invention is directed to that the cold and hot analogue experiment installation structure of bimetallic material of the prior art is complicated, operation bothers, cost an arm and a leg, the higher deficiency that can not satisfy the needs of correlative study of experimental expenses, a kind of double space material cold-heat simulation experiment device simple in structure, easy to operate, lower-cost is provided.
Double space material cold-heat simulation experiment device of the present invention, comprise the experimental provision body, it is characterized in that: described experimental provision body is provided with clamping device, lifting boosting mechanism, heating and heat-insulating device, fixed station and lifting frame, clamping device is made up of clamping device upper body and clamping device lower body, the clamping device upper body is arranged on the lifting frame, move up and down in company with the lifting frame, the clamping device lower body is arranged on the fixed station; The lower end of lifting frame is connected with the lifting boosting mechanism, moves up and down under the lifting boosting mechanism drives, and the lifting frame passes fixed station, and the lifting frame platform that is fixed is separated into work space and following work space; Several power that is connected with signal processing system and displacement transducers are set on the experimental provision body.
Further feature is: the lower end of lifting frame is provided with push pedal, and push pedal is connected with the lifting boosting mechanism; Form work space down between push pedal and the fixed station.
The cooled with liquid nitrogen device is set on the experimental provision body, and the cooled with liquid nitrogen device cools to being arranged on test specimen on the clamping device or that be arranged on down in the work space.
Double space material cold-heat simulation experiment device of the present invention, have advantages such as simple in structure, easy to operate, that cost is lower, can be widely used in research institutions, institution of higher learning and industrial and mining enterprises and carry out metal especially light alloy material heat, cold forming Mechanical Properties.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing:
Fig. 1 is the double space material cold-heat simulation experiment device structural drawing.
In Fig. 1, work space, 9-temperature controller, 10-signal processing system under 1-test specimen, 2-clamping device, 3-lifting boosting mechanism, 4-heating and heat-insulating device, 5-push pedal, 6-power and displacement transducer, the last work space of 7-, the 8-, 11-experimental provision body, the 12-fixed station, 13-lifting frame, 21-clamping device upper body, 22-clamping device lower body.
Embodiment
Double space material cold-heat simulation experiment device of the present invention, comprise experimental provision body 11, experimental provision body 11 is provided with clamping device 2, lifting boosting mechanism 3, heating and heat-insulating device 4, fixed station 12 and lifting frame 13, clamping device 2 is made up of clamping device upper body 21 and clamping device lower body 22, the upper and lower side of test specimen 1 is connected between clamping device upper body 21 and the clamping device lower body 22, clamping device upper body 21 is arranged on the lifting frame 13, move up and down in company with lifting frame 13, clamping device lower body 22 is arranged on the fixed station 12 and does not move up and down.The lower end of lifting frame 13 is connected with lifting boosting mechanism 3, under driving, lifting boosting mechanism 3 moves up and down, lifting frame 13 passes fixed station 12, lifting frame 13 platform 12 that is fixed is separated into work space 7 and following work space 8, carries out stretching experiment or is descending work space 8 to carry out compression experiment at last work space 7.Clamping device 2, heating and heat-insulating device 4 are arranged in the lifting frame 13, lifting boosting mechanism 3 is arranged on down usually in the work space 8 and (also can be arranged on down above the work space 8 or the outside), heating and heat-insulating device 4 is arranged in clamping device 2 next doors or the following work space 8, heating being arranged on test specimen 1 on the clamping device 2 or that be arranged on following work space 8 under the control action of temperature controller 9, reach the temperature and the insulation of technological requirement, the test specimen 1 that is arranged on work space 7 and following work space 8 is carried out stretching experiment or compression experiment at a certain temperature.For signals such as translational speed, stretching strength size are delivered in the signal processing system 10, with be arranged on the lifting frame 13 on the clamping device 2 or several power of other proper site be connected with signal processing system 10 with displacement transducer 6, power and displacement signal are transported in the signal processing system 10.
