Description

Technical Field

[0001] The utility model relates to the field of sample preparation tools, in particular to a die for ONH shearing sample safety and shape control. Background Art

[0002] The oxygen, nitrogen and hydrogen analyzer analyzes the gas content in steel, and needs to cut the tail of the sample for instrument analysis. Since the current status of the sample taken during the steelmaking process is in the shape of a table tennis racket, that is, one end is a round plate with an integrated metal tail on the round plate, the metal tail needs to be cut during shearing, and the detection section is fitted to the sensing end of the oxygen, nitrogen and hydrogen analyzer during detection. The sample is usually sheared by hand. Due to the principle of leverage, the sample is easy to warp up during shearing, which is not only easy to hurt the operator's hand, but also poses a safety factor. Moreover, after shearing, the tail of the sample is easy to be inclined, which is easy to get stuck at the feed port of the analyzer, which poses an unsafe factor to the equipment. In addition, there are thin strip samples of 1.2cm and other steel samples of 1.5cm in the factory, and the fixed state of rod samples of different specifications needs to be adjusted.

[0003] The utility model develops a mold for ONH shearing sample safety and shape control in order to solve the above problems. The mold is used to adsorb and fix the sampling sample in the shape of a table tennis racket, so that the sample does not warp and safety is guaranteed. Utility Model Content

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0034] In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not indicate the importance of the components, and therefore cannot be understood as a limitation on the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution, and do not limit the scope of protection of the present invention.

[0035] like Figure 1-7 As shown, a mold for ONH shearing sample safety and shape control includes a mounting mold 1, a magnet ring 2 is mounted on the inner side of the mounting mold 1, and a bolt member 3 is threadedly connected at the axis of the mounting mold 1;

[0036] The mounting mold 1 includes a limiting mold cavity 11 and a supporting pile 12, the supporting pile 12 is fixed at the top axis of the limiting mold cavity 11, and a notch 13 is provided on one side of the bottom of the limiting mold cavity 11, the limiting mold cavity 11 with the notch 13 matches the sampling sample for detection, and the sampling sample for detection is set in the shape of a table tennis racket;

[0037] The magnet ring 2 is used for adsorbing the sample for detection, and the magnet ring 2 is made of a permanent magnet;

[0038] The bolt member 3 rotates in the mounting mold 1, so that the distance between the top of the bolt member 3 and the bottom of the limiting mold cavity 11 can be changed, so that it can be adjusted according to different sample thicknesses. After the top and bottom of the device are fixed by a clamp, the metal segment tail of the sample is sheared by a shearing mechanism without manual support, and the sample will not have the problem of warping, thereby ensuring the flatness of the sample shearing surface and improving the safety and work efficiency of the analytical instrument.

[0039] Specifically, the bolt member 3 includes an adjusting end 31, a screw segment 32 and a limiting segment 33, the adjusting end 31 and the limiting segment 33 are respectively fixed at the top and bottom of the screw segment 32, and the outer diameters of the adjusting end 31, the screw segment 32 and the limiting segment 33 decrease successively.

[0040] Specifically, a threaded hole is opened at the axis of the support pile 12, and the screw rod segment 32 is threadedly connected to the threaded hole.

[0041] Specifically, a positioning hole is opened at the top axis of the limiting mold cavity 11, and the limiting section 33 is inserted into the positioning hole. The limiting section 33 is inserted into the core hole of the axis of the magnet ring 2, and the magnet ring 2 is adsorbed on the top wall of the inner cavity of the limiting mold cavity 11.

[0042] Specifically, the length of the screw segment 32 is greater than the thickness of the support pile 12, so that the device has a certain adjustment space, and the length of the limiting segment 33 is equal to the sum of the thickness of the positioning hole and the magnet ring 2, so that when the distance between the top of the bolt member 3 and the bottom of the limiting cavity 11 is the shortest, the bottom surface of the limiting segment 33 is flush with the lower surface of the magnet ring 2, thereby not affecting the fit of the sampling sample on the magnet ring 2 and the stability of the installation in the limiting cavity 11.

[0043] Specifically, the cross-sectional shapes of the support pile 12 and the adjustment end 31 are both set to regular polygons. A wrench is used to clamp the outer side of the support pile 12 to limit the position of the limiting mold cavity 11, and then the adjustment end 31 is twisted to facilitate the adjustment of the overall height of the device.

[0044] As a preferred embodiment, in order to adapt to the installation and use of sampling samples of different thicknesses, an extension frame plate 4 is added at the bottom of the limiting mold cavity 11, and the cross-sectional shape of the extension frame plate 4 corresponds to the limiting mold cavity 11, that is, the inner diameter size of the extension frame plate 4 and the limiting mold cavity 11 are consistent, and the position of the notch 13 is consistent, which is used to increase the accommodating cavity depth of the limiting mold cavity 11; specifically, a plurality of evenly distributed extension rods 5 are fixedly connected to the top of the extension frame plate 4, and the surface of the extension rod 5 is provided with an external thread, and the outer side of each extension rod 5 is connected to two nuts 6 through the external thread, and the outer side of the limiting mold cavity 11 is provided with through holes 7 distributed one by one with the extension rods 5, and the extension rods 5 slide inside the through holes 7, and the limiting mold cavity 11 is clamped by two nuts 6 to achieve the fixation of the position of the extension frame plate 4;

[0045] The usage of the extension frame plate 4 is as follows: when the sample thickness is relatively large, the actual accommodating depth of the limiting mold cavity 11 can be adjusted by adjusting the distance that the extension rod 5 passes through the through hole 7. After adjustment, two nuts 6 are used to clamp the limiting mold cavity 11 to fix the position of the extension frame plate 4.

[0046] As a preferred embodiment, in order to improve the stability of the sample after installation, a screw hole is opened on the extension frame plate 4, and the inner thread of the screw hole is connected to the abutment screw 8, which is screwed into the screw hole to clamp the sample for detection.

[0047] Specifically, the number of screw holes and abutment screws 8 is at least three, and the multiple screw holes and abutment screws 8 are distributed in a circular array, and a flat opening is opened on the outer wall of the extended frame plate 4 corresponding to the opening position of the screw holes to facilitate the abutment screws 8 to fit.

[0048] When the utility model is in use, an oxygen-nitrogen-hydrogen shearing machine is used to shear the tail of the sample, which is then used to analyze the gas content in the steel. The sample is placed in the accommodating chamber of the limiting mold cavity 11 by means of a magnetic ring 2, and the sample is sucked and placed in front of the blade of the shearing machine, with the distance just stuck at the upper and lower spacing openings, that is, at a spacing of 4 cmm, to fix the sample. During shearing, since the sample is fixed, it is not easy to warp up during the shearing process, thereby ensuring the flatness of the cut surface, solving the problem of sample jamming at the feed port of the analytical instrument, and improving the safety and work efficiency of the analytical instrument. No manual support is required during the shearing process, thereby ensuring the safety of personnel. The thread of the bolt member 3 can be adjusted up and down, and the spacing can be adjusted according to the thickness of the sample.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
