Compared with the traditional classification problem that whether the steel plate 13 is manually fed and discharged and whether qualified products are manually distinguished by a user, the automatic distinguishing of whether the steel plate 13 is qualified is realized by the aid of the rollers 501, the adjusting cylinder 202, the cylinder 401 and the motor 407, automatic control can be realized by the user only by one key after a single procedure is compiled, and the problem that whether the steel plate is manually fed and discharged and whether qualified products are manually classified by the user in the prior art is solved.

A use method of a steel plate flexural strength detection device specifically comprises the following steps:

s1, firstly, a user can connect the device with an external steel plate 13 conveying line, then in the using process, the steel plate 13 can be conveyed to the upper parts of the driving roller 201 and the driven roller 207 through the conveying line and the right roller 501 and stopped to advance under the blocking of the blocking rod 301, at this time, the steel plate 13 can be separated from the roller 501 and completely fall above the driving roller 201 and the driven roller 207, the output shaft of the adjusting cylinder 202 is controlled to retract, the sleeve plate 206 and the round rod 205 synchronously move downwards, the inclined plate 204 can only rotate outwards due to the sliding clamping of the round rod 205 and the inclined plate 204, the heights of the driving roller 201 and the driven roller 207 are reduced, and the steel plate 13 falls above the first transverse plates 16 on the two sides.

S2: after the steel plate 13 is placed, the output shaft of the detection hydraulic cylinder 10 can be controlled to extend out, the pressure sensor 17 and the detection roller 11 are enabled to move downwards, the detection roller 11 is enabled to be pressed at the center of the upper surface of the steel plate 13 to detect the bending strength of the steel plate, the pressure applied above the steel plate 13 can be transmitted to an external display screen in real time through the pressure sensor 17, but when the bending strength is detected, the steel plate 13 usually deforms along with the increase of the pressure, but the deformation still occurs under the condition of smaller pressure, if the requirement on the bending strength of the steel plate 13 is larger, namely the deformation amount is smaller, a user cannot judge whether the bending strength reaches the standard through observing the bending change of the steel plate 13 by naked eyes, at the moment, the user can open the two laser transmitters 14, the emitted laser beams can irradiate on the opposite scale blocks 208, and the steel plate 13 is horizontal under the condition of not applying pressure, when steel sheet 13 takes place deformation under the applied pressure condition, its terminal rotation transmits to laser emitter 14 department through first diaphragm 16 and second diaphragm 15, make laser emitter 14 along with together rotating, because laser emitter 14 and scale block 208 set up the one side on steel sheet 13 on the one side of both sides, therefore when it takes place the miniaturely deformation, the laser beam that laser emitter 14 sent also can take place great skew at scale block 208, once the skew is crossed specific scale and can be proved steel sheet 13 and can't reach corresponding bending strength, the deformation degree of having avoided the tradition to observe steel sheet 13 through the naked eye determines bending strength not accurate problem.

S4: in the process of extending the output shaft of the adjusting hydraulic cylinder 202, the output shaft thereof can drive the second slider 307 to move upwards through the push rod 303, meanwhile, due to the clamping connection between the clamping block 310 and the clamping groove 304, the second slider 307 can drive the first slider 305 to move upwards through the clamping block 310, and further drive the material blocking rod 301 to ascend, so that the blocking is removed for the movement of the steel plate 13, when the driving roller 201 and the driven roller 207 reach a sufficient height, the output shaft of the adjusting hydraulic cylinder 202 stops extending, the steel plate 13 is conveyed leftwards through the driving roller 201, after the conveying is completed, the output shaft of the adjusting hydraulic cylinder 202 needs to extend and retract for a certain distance, in the process of moving the second slider 307 upwards, the inclined rod 308 is blocked by the cushion block 306 to move leftwards, the clamping connection between the clamping block 310 and the clamping groove 304 is removed, at this time, the first slider 305 can be influenced by the elastic force of the second spring 311 to drive the material blocking rod 301 to move downwards to reset, the steel plate 13 used for blocking the next detection is used, after the next steel plate 13 is transported to the driving roller 201 and the driven roller 207, when the output shaft of the adjusting hydraulic cylinder 202 descends again, the second sliding block 307 descends along with the second sliding block 307, but because the arc design is adopted below the tail end of the clamping block 310, the clamping block 310 can be extruded and retracted continuously, and is popped out and retracted again, until the clamping block 310 and the clamping groove 304 at the lowest end form clamping connection as shown in fig. 11, the automatic lifting control of the material blocking rod 301 according to needs can be realized through circulation, and the problem that interference easily occurs in the matching use process when the occupied space is large due to the fact that the material blocking rod 301 is provided with a driving structure independently is avoided.

S5: if the deformation of the steel plate 13 exceeds the preset range after detection is finished, the quality of the steel plate 13 is proved to be unqualified, at the moment, the output shaft of the detection hydraulic cylinder 10 is controlled to extend out to the limit length, the steel plate 13 is extruded to the limit position with the bending angle of 30 degrees, then the output shaft of the detection hydraulic cylinder 10 retracts, meanwhile, the air cylinder 401 drives the power box body 403 to move upwards, in the moving process, the rotating wheels 405 with 30-degree inclined planes are machined on the inner walls of the four corners to jack up the steel plate 13, the steel plate 13 moves upwards for a distance, and when the front end position is not blocked by the upright post 8 and the driven roller 207 any more, the motor 407 is controlled to start, so that the motor 407 is matched with the driving gear 410, the driven gear 406, the chain 411 and the chain wheel 409 to realize synchronous rotation of the plurality of rotating wheels 15, the unqualified steel plate 13 is sent out forwards, and the material is reset through the air cylinder 401 after the material is finished.

No matter detect whether qualified back at steel sheet 13, the control through a plurality of rollers 501 and adjustment cylinder 202 of this scheme realizes the transport of qualified products and discharges, the transport of having realized unqualified product is discharged through cylinder 401 and motor 407 control, compare in the design of driven single detection achievement platform, this scheme has adopted the streamlined design of relative intelligence, greatly reduced operator's manual labor and detection efficiency, avoided carrying on the lower problem of a large amount of steel sheet rupture strength testing process detection efficiency.
