Background technology
Plastic hot deformation test machine is used for the thermal deformation behavior of plastics is tested; Generally comprise a casing, hold silicone oil in the casing, the plastics batten is placed silicone oil and silicone oil is heated; Thereby the plastics batten is heated, distortion under the pressure effect of feeding pressure mechanism simultaneously.The existing feeding pressure mechanism complex structure that is used for plastics are carried out the thermal deformation test is difficult to obtain accurate test findings when the plastics batten is exerted pressure.
Summary of the invention
In order to overcome the existing above-mentioned deficiency that is used for plastics are carried out the feeding pressure mechanism of thermal deformation test, the utility model provide a kind of simple in structure, can obtain the feeding pressure mechanism that accurate test findings is used for plastics are carried out the thermal deformation test.
The technical scheme that the utility model solves its technical matters is: a kind of feeding pressure mechanism that is used for plastics are carried out the thermal deformation test; Comprise installing plate; Be equipped with depression bar on the described installing plate; The upper end of said depression bar is provided with the counterweight seat of the level that is positioned at said installing plate top, and the bottom of said depression bar is positioned at the below of said installing plate;
The upper surface of said installing plate also is provided with a vertical pole, is with elevating bracket on the described pole, is equipped with the up-down fastening screw on the described elevating bracket; Described elevating bracket is provided with displacement transducer, and the lower end measuring head of said displacement transducer is aimed at described counterweight seat;
The lower surface of said installing plate is provided with electrothermal tube;
The lower surface of said installing plate also is provided with the batten frame that is used to place the plastics batten, and the plastics batten places aligning described depression bar in back on the described batten frame.
Further; The head of said installing plate is provided with two preceding hack levers, hack lever after the afterbody of said installing plate is provided with two, and the lower end of two preceding hack levers connects through the side arm bar; The lower end of hack lever connects through the after-frame bar after two, and the plastics batten is shelved on described side arm bar and the after-frame bar.
Further, also be provided with handle on the upper surface of said installing plate.
The utility model places batten on the batten frame in use, and batten is dipped in the silicone oil and heats.On the counterweight seat of depression bar upper end, add counterweight, accurately control the downforce of depression bar, make the lower end measuring head of the position displacement transducer that it is extremely suitable that elevating bracket goes up and down prop up counterweight or counterweight seat thereby unclamp the up-down fastening screw.Batten is heated the back deliquescing, and flexural deformation under the downforce effect of depression bar is measured displacement thereby the lower end measuring head of displacement transducer moves down along with the distortion of batten.
The beneficial effect of the utility model is: simple in structure, and accurately control the downforce of depression bar and the deflection after the batten distortion quarter, thus obtain accurate test findings.
