Description
(1) technical field
The utility model relates to a kind of impact testing machine.
(2) background technology
Impulse test is that research material is for a kind of test of live load drag, different with dead weight, because loading velocity is fast, stress in the material is improved suddenly, deformation velocity has affected the character of institution of material, so material shows another kind of reaction to dynamic load effect, often under quiet lotus, have the material of fine plastic property, under shock load, can present the character of fragility.The impact test piece of common metal material is generally at the rectangle test specimen with gap slot on the engineering, and the purpose of making goods is for the ease of disclosing each factor to the impact of the impact resistance of material when being out of shape at a high speed.Notch geometry and sample dimensions are very big on the impact of the impact toughness value of material, guarantee that experimental result can compare, test specimen must be made in strict accordance with the cloth standard promulgated by the ministries or commissions of the Central Government of Ministry of Metallurgical Industry, is in fact a kind of competitive trial therefore measure impact toughness value impact experiment.At present experimental facilities commonly used basic is by frame, fixedly jaw seat, ballistic pendulum, measurement mechanism and the catanator of sample form, during use ballistic pendulum raise put be hung on frame raise on the arm after, ballistic pendulum has obtained a gravitional force, when ballistic pendulum freely falls, then gravitional force turns to kinetic energy sample is thrust, after thrusting sample, ballistic pendulum still can remaining kinetic energy be raised to the one height until remaining kinetic energy all changes into gravitional force and finishes whole impulse test.In whole impulse test process, can calculate the merit that consumes when sample thrusts according to law of conservation of energy, be called ballistic work.Ballistic work is then drawn needed test findings divided by the indentation, there cross-sectional area: the impact toughness value.
But because above-mentioned experimental facilities is simple in structure and unreasonable, cause following points not enough: when 1, ballistic pendulum falls roll offset to occur very easily, cause its striking point misalignment sample break position; 2, can only be confined to do the impulse test of several energy.
(3) summary of the invention
For addressing the above problem, the utility model provides a kind of impact testing machine, guarantees its striking point alignment notch position when experiment, and is adapted to the impulse test of a plurality of energy.
For this reason, the utility model adopts following scheme to achieve the above object:
A kind of impact testing machine, comprise frame, ballistic pendulum, ballistic pendulum releasing means and jaw seat, described frame extend horizontally away an installation shaft, the ballistic pendulum releasing means has a sway brace, sway brace one end is installed on the installation shaft, be provided with flexible controlled back-up block on the sway brace other end, it is characterized in that: ballistic pendulum is sector structure, which is provided with the counterweight hole that at least one can assemble the different quality counterweight, its small end is provided with axis hole and cooperates installation with installation shaft on the described frame, and its large end is provided with the impact blade.
Above-mentioned a kind of impact testing machine, it is characterized in that: frame is provided with register pin, described sway brace is provided with chute, and sway brace is fixed on the frame after the rotatable certain angle of the central shaft of described installation shaft makes register pin be positioned at described chute two ends and through a holding screw.
The utility model has the advantage of: in its striking point alignment notch position of when experiment, and be adapted to the impulse test of a plurality of energy.
(4) description of drawings
Fig. 1 is the utility model three-dimensional state schematic diagram;
Fig. 2 is the decomposing state schematic diagram of sway brace.
(5) embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Impact testing machine comprises: frame 1, ballistic pendulum 2, ballistic pendulum releasing means 3 and jaw seat 4.Described frame 1 extend horizontally away an installation shaft 11, ballistic pendulum releasing means 3 has a sway brace 31, sway brace 31 1 ends are installed on the installation shaft 11, frame 1 is provided with register pin 51, described sway brace 31 is provided with chute 52, and sway brace 31 is fixed on the frame 1 after the rotatable certain angle of the central shaft of described installation shaft 11 makes register pin 51 be positioned at described chute 52 two ends and through a holding screw.Be provided with flexible controlled back-up block 31-1 on sway brace 31 other ends.
Ballistic pendulum 2 is sector structure, which is provided with the counterweight hole 21 that at least one can assemble the different quality counterweight, makes ballistic pendulum 2 obtain different impact energys, is adapted to the impulse test of a plurality of energy.Its small end is provided with axis hole and cooperates installation with described installation shaft 11, and large end is provided with and impacts blade 22.
This impact testing machine can be used for semi-girder test and free beam test.Differently arrange different impact positions according to what semi-girder test and free beam were tested impact velocity, carry out the semi-girder test, upwards kick up sway brace 31 to sway brace 31 upper limit position places (being the end that register pin 51 is positioned at described chute 52), and the holding screw of locking by through hole 53 is fixed on the frame 1.If carry out charpy impact test, locate (being the other end that register pin 51 is positioned at described chute 52) to the lower position to pressing down sway brace 31, and the holding screw of locking by through hole 53 is fixed on the frame 1.Be provided with flexible controlled back-up block 31-1 on sway brace 31 other ends and stretch out at this moment, can allow it put to certain altitude by putting for ballistic pendulum 2.In the time will discharging ballistic pendulum 2, to press the button that links with back-up block 31-1 and make back-up block 31-1 indentation sway brace 31, ballistic pendulum 2 loses dependence and falls.
Be necessary to be pointed out that at this above embodiment only is used for the utility model is further specified; can not be interpreted as the restriction to the utility model protection domain, the those of ordinary skill in this field can be made some nonessential improvement and adjustment to above embodiment according to essence of the present utility model.
