Background

For steel plants producing thick plates, the requirements on the directional performance of the thickness of the thick plate are more and more common along with the gradual improvement of the comprehensive quality requirements of users on the thick plate. Compared with a strip sample parallel to the rolling direction or perpendicular to the rolling direction, the performance detection in the thickness direction of a common thick plate is limited by the thickness range of the plate, and the plate cannot be processed into a tensile sample which can be directly tested by a testing machine, so that the testing machine cannot directly test the sample, and the thickness direction test must be realized by an auxiliary processing means. The current common method is as follows: firstly, a part to be tested in the thickness direction of a thick plate is manufactured into a square test block with the length of about 30mm, then two ends of the test block are respectively welded with a bar-shaped test sample with the length of about 200mm by a friction welding machine or other modes, after cooling, the test block part is turned to the diameter (10mm or 6mm) required by the standard by a lathe or a machining center and other equipment, then the bar-shaped parts welded at the two ends are placed in a jaw of a testing machine, the testing machine is started to apply tension until the middle turned thickness direction part is broken, and the broken part is measured, so that the performance test in the thickness direction of the thick plate is realized. The purpose of welding the two ends of the test piece in the thickness direction into a rod shape is to clamp and apply force to the rod-shaped part so as to realize the tensile test of the test piece in the thickness direction. The main process is shown in fig. 4.

The main problems existing in the prior method are that the whole testing process is long in time consumption due to the welding, cooling and reprocessing processes, and more materials, equipment and the like are wasted in the whole process. Meanwhile, if the welding quality is unqualified or the welding seam is broken during testing, the testing cannot be carried out, and the processes of sampling, sample preparation, welding, processing, testing and the like must be carried out again for retesting.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings.

Example 1

As shown in fig. 1 and 2, an economic steel sheet thickness performance test isolated plant, including fixed block 1 and small sample 4, fixed block 1 is provided with two altogether, and one side that two fixed blocks 1 are adjacent all is equipped with bayonet socket 2, and one side that two fixed blocks 1 are adjacent all is equipped with draw-in groove 3, and draw-in groove 3 is linked together with bayonet socket 2, and small sample 4 both ends are located draw-in groove 3.

The clamping groove 3 is of a trapezoidal structure.

Two ends of the small sample 4 are in a trapezoidal cone structure 5.

Example 2

The utility model provides an economic steel sheet thickness capability test isolated plant, includes fixed block 1 and small sample 4, fixed block 1 is provided with two altogether, and 1 adjacent one side of two fixed blocks all is equipped with bayonet socket 2, and 1 adjacent one side of two fixed blocks all is equipped with draw-in groove 3, and draw-in groove 3 is linked together with bayonet socket 2, and 4 both ends of small sample are located draw-in groove 3.

The clamping groove 3 is of a trapezoidal structure.

And two ends of the small sample 4 are cylindrical structures 6.

For the steel plate needing to be subjected to thickness performance detection, a small block sample in the thickness direction is directly processed into a miniature dumbbell sample without welding auxiliary rod-shaped samples at two end parts and cooling reprocessing processes. When carrying out thickness direction experiment, place this economic steel sheet thickness capability test isolated plant on the testing machine is kept silent and the centre gripping, place the both ends that will process good both ends for trapezoidal cone structure 5 or cylindrical structure 6's small sample 4 in draw-in groove 3, the bayonet socket has further ensured the fastness of blocking trapezoidal cone structure 5 or cylindrical structure 6's small sample 4, then start the test machine and just directly realized the test of thickness directional capability. Therefore, the waste of equipment and materials is saved, the time consumption of the process is greatly shortened, and the efficiency is improved, so that the economical high-efficiency thick steel plate thickness direction performance test is realized.

The processes of welding, cooling and reprocessing by adopting a rod-shaped sample are avoided; the consumption of more materials and equipment is avoided, the whole detection process is greatly shortened, the detection efficiency is improved, the thickness direction performance detection of the economical thick plate is realized, and the welding is avoided, so that the factors influencing the material performance by welding are avoided, and the test precision is ensured. Meanwhile, the problems of welding quality or full-process repeated machining sample preparation and detection caused by fracture of the welding seam during testing are avoided.

The present invention is not limited to the above embodiments, and any structural changes made under the teaching of the present invention shall fall within the scope of the present invention, which is similar or similar to the technical solutions of the present invention.
