Description
Technical field
The present invention relates to a kind of wire bending fatigue test device, particularly steel cord bending fatigue test device.
Background technology
Fast development along with automobile industry; The user has proposed higher quality requirements to tire; Then tire plant is also increasingly high to the quality requirements of steel cord, and steel cord factory constantly increases the test item of cord quality thereupon, comprises the torsional fatigue, repeated bend test of steel cord etc.Existing armored rope bending fatigue testing machine; It mainly is made up of driving wheel, crooked pulley and load travelling block etc.; Two ends are fixed on the driving wheel behind wire rope pile warp driving wheel, crooked pulley and the load travelling block; It is reciprocating to drive driving wheel with transmission shaft, drives crooked pulley and makes sample in effective length, carry out the unidirectional alternating bending in plane.It is bigger that this installs crooked diameter of pulley, and the complete machine running speed is low, and testing efficiency is low; And wire is complicated; Reduced the flexible life of cord, only be applicable to wire rope, be not suitable for the thinner bending fatigue test that attaches the steel cord behind the glue of diameter than coarse texture.
Summary of the invention
The present invention provides a kind of wire bending fatigue test device, and it is simple in structure, and testing efficiency is high.
The present invention has adopted following technical scheme: a kind of wire bending fatigue test device; It comprises frame and motor; It also comprises input shaft, traction link, connecting rod, some groups of escapements and muller; Said motor drives input shaft through gearing and rotates, and said input shaft end face is provided with guide runner; In the combination of escapement and muller, the escapement that the back is a group through connecting rod with last group in escapement be connected, the escapement in the most last group passes through traction link and is connected with said guide runner; The drive end bearing pin of said traction link is connected with said guide runner, and the driven end bearing pin of said traction link is connected with the escapement in the most last group, and the deep-slotted chip breaker that said driven end bearing pin is positioned at frame can slide along deep-slotted chip breaker; Said escapement and muller side face are provided with wire casing, and its two ends are fixed on the escapement behind wire rod pile warp muller to be measured and the escapement side face wire casing, and then said muller is hung below escapement by wire rod to be measured, is hung with counterweight load on the said muller.
The diameter of muller described in the present invention is much smaller than escapement; Said connecting rod is connected through bearing pin with escapement, and said bearing pin is supported by bearing.Said muller is connected with guide rod by the bearing supporting, and said counterweight load is hung in said guide rod below.Said frame is provided with guide holder, and said guide rod is hung said counterweight load after passing guide holder.
The present invention has following beneficial effect: owing to adopted as above technical scheme, the present invention mainly is made up of motor, input shaft, traction link, escapement and muller, rotates through the driven by motor input shaft; Input shaft turns around, and drives the swing of escapement left and right directions once through traction link, and the muller diameter is merely 1/tens of escapement; The escapement pendulum once; Rolling wheel then rotates some circles, and cord constantly comes back bending bent on rolling wheel like this, reach certain ultimate value after; Cord just can be disrumpent feelings, thereby measure the bending fatigue limit of tapping cord.The diameter of muller is set in cord thickness ratio in this device; Be characterized in the muller diameter much smaller than escapement, velocity of rotation is fast, and detection efficiency is high; Wire rod to be measured is sulfuration steel cord; Be that cord has coated rubber layer outward, the parameter of detection is not only the physical property of steel cord, the more important thing is the bending fatigue performance after detecting rubber and cord combining.Regulate the amplitude of oscillation that the position of input shaft guide runner can the appropriate change escapement.The present invention has omitted crooked pulley, has changed wire rod wire circuit, and is simple in structure, reduced the volume of proving installation.The present invention includes some groups of escapements and muller, can measure the bending fatigue limit of a plurality of wire rods simultaneously, improved testing efficiency.Frame is provided with guide holder, and guide rod is hung counterweight load after passing guide holder, defines the direction of motion of guide rod through guide holder, prevents that counterweight load from swinging.
