[embodiment]:
Embodiment 1
As shown in Figure 1, 2, number in the figure is represented respectively:
1, air pump, 2, electricity, gas intelligence control system, 3, the vertical back up pad in left side, 4, the vertical back up pad in right side, 5, sample bench elevating screws bar, 6, the sample cell inner-support, 7, pressure head, 8, air inlet air pressure divider, 9, add carrier gas cylinder, 10, draft tube, 11, the air pressure divider of giving vent to anger, 12, escape pipe, 13, pressure governor, 14, upper strata transverse slat, 15, middle layer transverse slat sample bench, 16, bottom connects transverse slat.
The present invention includes two vertical back up pads 3,4 of main frame, installation adds the upper strata transverse slat 14 of carrier gas cylinder, be positioned at 5 cylinders 9 (this routine N selects 5) on the transverse slat of upper strata, middle layer transverse slat sample bench 15, be positioned at the fulcrum 6 of sample cell, pressure head 7 on the cylinder connecting link, bottom connects transverse slat 16, with be positioned at bottom and be connected on the transverse slat 4 screw rods 5 of regulating the sample bench lifting, be positioned at the inlet, outlet air pressure divider 8,11 of upper strata transverse slat, power source air pump 1, pressure governor 13, draft tube 10, escape pipe 12.Comprised 4V410-15 solenoid valve, source of the gas processing and regulating element in electricity, the gas control system system 2, TPD-104 programmable timer, HB48 numeral product device and on-off control system etc., control circuit is referring to Fig. 3.
Principle of work of the present invention and process: the gases at high pressure that utilize the 0.8Mpa that air pump 1 provides, processing and decompression back through pressure governor 13 flow to five cylinders 9 equably by air pressure divider 8,11, the size of the power output that cylinder produces be the diameter of cylinder piston and the common decision of air pressure (under condition with pressure, the diameter of cylinder piston is big more, and the pressure of output is also big more).The pressure of this programme design output 60～70KG loads by 7 pairs of samples of the pressure head on the cylinder connecting link.Tested sample is installed between two fulcrums 6 in the sample cell of middle layer transverse slat, adopts the design of sample cell, can prevent from that sample from producing to come off when stress deformation.In addition, also considered the versatility of sample in design, on the spacing of sample fulcrum, designed 32mm and two kinds of 64mm are available according to the regulation of national standard.The adjustment of the distance of middle layer transverse slat sample bench 15 and pressure head 7 is to realize by 4 spiral lifting mechanisms 5, makes 5 samples stressed evenly by adjustment.In addition, two air pressure dividers 8,11 are installed on the upper strata transverse slat of agent structure, make the gas path layout of fatigue tester more become reasonable.
In order to satisfy the requirement of different materials to test parameters, the present invention has prepared TPD-104 programmable timer, HB48 numeral product device, 4V410-15 solenoid valve and on-off control system in electricity, gas intelligence control system 2.Programmable timer is used for adjusting loading frequency, the frequency-tuning range of this testing machine: f＜1HZ is adjustable continuously, and the length that adds discharge time can be set arbitrarily, numeral product device is used for writing down cycle index, make fatigue tester under the situation of no worker monitor, automatically shut down according to predefined cycle index.On-off control system then is to realize the necessary logic of above action.
The present invention mainly is that (60～70KG) fatigue bending machines, coupons can be varying sized arbitrarily under the condition that satisfies span and maximum load for the little load that designs in order to satisfy metal and non-metallic sheet.
