Description

Technical Field

[0001] The present application relates to the technical field of steel plate sampling, and in particular to a steel plate sampling and marking device. Background Art

[0002] For the steel plate after rolling, in order to verify its performance, it is necessary to sample and process the steel plate at different positions according to the standard requirements. In order to reduce the waste caused by sampling and improve the efficiency of sample processing, it is necessary to sample the steel plate according to a certain size. The sampling of the steel plate is to divide a rectangular area on the steel plate, and then cut this area and send it for testing.

[0003] The existing steel plate marking method is usually single-rule marking. This marking method has great defects. Single-rule marking needs to be repeated many times. Moreover, since there is no marking line when marking with a single ruler, it is difficult to make the new marking line relatively parallel or relatively perpendicular to the original marking line. Therefore, it is difficult to mark the standard rectangular plate area when using the traditional marking method. It is easy to mark the rectangular shape into a trapezoid or parallelogram. There are problems such as irregular marking, large errors, and the shape of the divided area does not meet the technical requirements. In addition, the traditional marking efficiency is low, which ultimately affects the quality and construction progress. Utility Model Content

[0066] As part of the creative concept of the present application, before describing the embodiments of the present application, it is necessary to analyze the causes of the problems in the related art, such as cumbersome operation, low efficiency and non-compliance of the sampling line marks when sampling steel plates, and obtain the technical solution of the embodiments of the present application through reasonable analysis.

[0067] In the related technology, the steel plate needs to be tested for physical and mechanical properties before use to ensure the processability and safety of the steel plate. For the rolled steel plate, in order to verify its performance, it is necessary to sample and process the steel plate at different positions according to the standard requirements. In order to reduce the waste caused by sampling and improve the efficiency of sample processing, the steel plate needs to be sampled according to a certain size. For example, the steel plate tensile impact test generally takes a 70*750mm rectangular sample at 1 / 4 of the width of the steel plate, and the drop-weight tear test (DWTT) generally takes a 100*850mm rectangular sample at 1 / 4 of the width of the steel plate.

[0068] At present, online mechanical automated sampling can be adopted for thin-gauge steel plates, but for thick-gauge steel plates or steel plates sampled after landing, it is first necessary to mark the sample size on the steel plate, and then use equipment such as fire cutting to cut according to the marked line. The existing steel plate marking method is usually single-rule marking, that is, a steel ruler is used for single-rule single-side marking, which requires multiple operations, and the steel ruler is easy to move during the marking process, resulting in inaccurate marking. At the same time, there is also the situation that two adjacent markings are not perpendicular, which is easy to cause problems such as irregular marking, difficulty in single-person operation, and non-rectangular area shape, which will seriously affect the subsequent sample processing, resulting in sample shortage or failure to be flush or perpendicular to the rolling direction of the steel plate, thereby affecting the inspection results.

[0069] To this end, the present application provides a steel plate sampling and marking device, which includes a main scale and a secondary scale that are perpendicular to each other. The main scale and the secondary scale are each equipped with a sliding block that can slide along the length direction of the main scale and the secondary scale. The sliding block can carry a marking pen, and the marking pen can perform marking operations along the right angle relationship formed by the main scale and the secondary scale, thereby ensuring that the marking marks on the steel plate can form a standard rectangular area. In addition, the device is simple to operate, highly efficient and can be operated by one person, thereby solving the technical problems in the prior art of complicated operation, low efficiency and non-compliance of the sampled marking marks when sampling steel plates.

[0070] The technical solutions of the embodiments of the present application are described in detail below in conjunction with the accompanying drawings. The technical features involved in the different implementation modes of the present application described below can be combined with each other as long as there is no conflict between them.

[0071] For reference Figures 1 to 3 , Figure 1 A schematic diagram of a top view of a steel plate sampling and marking device provided in some embodiments of the present application; Figure 2 A schematic diagram of a three-dimensional structure of a main ruler provided in some embodiments of the present application; Figure 3 A schematic diagram of the three-dimensional structure of a secondary ruler provided in some embodiments of the present application.

[0072] In an embodiment of the present application, a steel plate sampling and marking device is provided, such as Figures 1 to 3 As shown, the steel plate sampling and marking device comprises a main ruler 1, a sub-rule 2, a first sliding block 3 and a second sliding block 4; wherein the main ruler 1 and the sub-rule 2 are arranged perpendicularly and fixedly connected at one end along their respective length directions, and the main ruler 1 and the sub-rule 2 form a perpendicular relationship, that is, the length direction of the main ruler 1 is perpendicular to the length direction of the sub-rule 2. The first sliding block 3 is slidably assembled with the main ruler 1, and the marking pen 6 is assembled on the first sliding block 3 and can mark the steel plate along the length direction of the main ruler 1; the second sliding block 4 is slidably assembled with the sub-rule 2, and the marking pen 6 is assembled on the second sliding block 4 and can mark the steel plate along the length direction of the sub-rule 2; the marking pen 6 can use the perpendicular relationship between the main ruler 1 and the sub-rule 2 to quickly complete the marking operation on the steel plate, and make the marking area a standard rectangular area.

[0073] In this embodiment, the main ruler 1 can be in the shape of a long strip, and a first scale 11 is provided along the length direction of the main ruler 1. The two ends of the first scale 11 are a starting scale line (0 scale line) and an ending scale line, respectively. The range from the starting scale line to the ending scale line can be regarded as the measuring range of the main ruler 1. Specifically, the measuring range of the main ruler 1 can be 30 cm, 60 cm, 90 cm, etc., and the graduation value can be 1 mm; the arrangement direction from the starting scale line to the ending scale line in the first scale 11 is consistent with the length direction of the main ruler 1; the first scale 11 can be used to read the sliding distance of the first sliding block 3 on the main ruler 1, and the sliding distance can be regarded as the marking size of the marking pen 6 mounted on the first sliding block 3 acting on the steel plate.

[0074] In this embodiment, the secondary ruler 2 can be in the shape of a long strip, and a second scale 21 is provided along its length direction. The two ends of the second scale 21 are a starting scale line (0 scale line) and an ending scale line, respectively. The starting scale line to the ending scale line can be regarded as the measuring range of the secondary ruler 2. Specifically, the measuring range of the secondary ruler 2 can be 30cm, 60cm, 90cm, etc., and the graduation value can be 1mm; the arrangement direction from the starting scale line to the ending scale line in the second scale 21 is consistent with the length direction of the secondary ruler 2; the second scale 21 can be used to read the sliding distance of the second sliding block 4 on the secondary ruler 2, and the sliding distance can be regarded as the marking size of the marking pen 6 mounted on the second sliding block 4 acting on the steel plate.

[0075] In this embodiment, the first sliding block 3 may be in the shape of a rectangular parallelepiped, and the first sliding block 3 is mounted on the main scale 1 and can slide along the length direction of the main scale 1. The first sliding block 3 is provided with a first mounting hole 31 for the marking pen 6 to pass through, and the first mounting hole 31 passes through the first sliding block 3 along the thickness direction of the main scale 1. After the marking pen 6 is assembled on the first sliding block 3, it can move along with the first sliding block 3 to complete the marking operation on the steel plate; wherein, the outer peripheral wall of the marking pen 6 is adapted to the first mounting hole 31, and the tip of the marking pen 6 can fall on the steel plate after passing through the first mounting hole 31, and the first mounting hole 31 can limit the marking pen 6 to be in a vertical state relative to the plate surface of the steel plate to be marked, so as to prevent the marking pen 6 from deflecting during the marking process.

[0076] In this embodiment, the second sliding block 4 may be in the shape of a rectangular parallelepiped, and the second sliding block 4 is mounted on the secondary ruler 2 and can slide along the length direction of the secondary ruler 2. The second sliding block 4 is provided with a second mounting hole 41 for the marking pen 6 to pass through, and the second mounting hole 41 passes through the second sliding block 4 along the thickness direction of the secondary ruler 2. After the marking pen 6 is assembled on the second sliding block 4, it can move along with the second sliding block 4 to complete the marking operation on the steel plate; wherein, the outer peripheral wall of the marking pen 6 is adapted to the second mounting hole 41, and the tip of the marking pen 6 can fall on the steel plate after passing through the second mounting hole 41, and the second mounting hole 41 can limit the marking pen 6 to be in a vertical state relative to the plate surface of the steel plate to be marked, so as to prevent the marking pen 6 from deviating during the marking process.

[0077] It should be noted that the end where the main ruler 1 and the secondary ruler 2 are connected is defined as the connecting end; when the first sliding block 3 slides to the position closest to the connecting end, the position where the marking pen 6 penetrating the first mounting hole 31 falls on the steel plate is defined as the first position; when the second sliding block 4 slides to the position closest to the connecting end, the position where the marking pen 6 penetrating the second mounting hole 41 falls on the steel plate is defined as the second position; wherein, when the main ruler 1 and the secondary ruler 2 are fixed on the steel plate, the first position and the second position may coincide, and the coincidence of the two positions means that the starting point of the marking pen 6 for marking along the length of the main ruler 1 and the starting point of the marking pen 6 for marking along the length of the secondary ruler 2 may coincide, so that two adjacent lines in the rectangular area (marking mark area) drawn by the marking pen 6 on the steel plate may connect at the same point (i.e., the vertices of the two lines), so as to ensure that the rectangular area drawn by the marking pen 6 meets the sampling requirements.

[0078] In this embodiment, since the main ruler 1 and the auxiliary ruler 2 are arranged vertically, and the marking pen 6 can move along with the first sliding block 3 or the second sliding block 4 in the length direction of the main ruler 1 or the auxiliary ruler 2 to mark, when the device is used to take samples on the steel plate, the marking marks on the steel plate can measure out a standard rectangular area; in addition, the main ruler 1 and the auxiliary ruler 2 are provided with scales, the first sliding block 3 or the second sliding block 4 can move along the corresponding scales, and the marking pen 6 can be carried to quickly complete the marking operation, and it can be operated by a single person, which simplifies marking and improves efficiency.

[0079] For reference Figure 1 , Figure 4 and Figure 5 , Figure 1 A schematic diagram of a top view of a steel plate sampling and marking device provided in some embodiments of the present application; Figure 4 A schematic diagram of a three-dimensional structure of a first sliding block provided in some embodiments of the present application; Figure 5 A schematic diagram of the three-dimensional structure of a second sliding block provided in some embodiments of the present application.

[0080] In some embodiments, Figure 1 , Figure 4 and Figure 5 As shown, the first sliding block 3 has two first side surfaces that are relatively arranged in the length direction of the main scale 1, and the first side surface relatively far away from the connection end of the two first side surfaces is defined as the first standard surface 32; the side scale line of the first scale 11 close to the connection end is the starting scale line of the first scale 11; when the first sliding block 3 slides to the position closest to the connection end, the first standard surface 32 is aligned with the starting scale line of the first scale 11 in the thickness direction of the main scale 1. At this time, the position where the marking pen 6 installed on the first sliding block 3 falls on the steel plate is the first position, that is, the starting point when the marking pen 6 marks along the length of the main scale 1.

[0081] In this embodiment, the abutment relationship between the first sliding block 3 and the connecting end can be used to associate the starting scale line on the main scale 1 with the starting point of the marking pen 6 when marking along the length of the main scale 1, that is, when the first standard surface 32 of the first sliding block 3 is aligned with the starting scale line of the first scale 11, the marking pen 6 is exactly at the starting point of the marking. With the above-mentioned structural design, the sliding distance of the first sliding block 3 on the main scale 1 (that is, the size of the marking line applied by the marking pen 6 on the steel plate) can be easily read, thereby improving the work efficiency of the marking operation.

[0082] Similarly, the second sliding block 4 has two second side surfaces relatively arranged in the length direction of the secondary ruler 2, and the second side surface relatively far away from the connecting end of the two second side surfaces is defined as the second standard surface 42; the side scale line of the second scale 21 close to the connecting end is the starting scale line of the second scale 21; when the second sliding block 4 slides to the position closest to the connecting end, the second standard surface 42 is aligned with the starting scale line of the second scale 21 in the thickness direction of the secondary ruler 2. At this time, the position where the marking pen 6 installed on the first sliding block 3 falls on the steel plate is the second position (the first position coincides with the second position), that is, the starting point when the marking pen 6 marks along the length of the secondary ruler 2.

[0083] In this embodiment, the abutment relationship between the second sliding block 4 and the connecting end can be used to associate the starting scale line on the secondary ruler 2 with the starting point of the marking pen 6 when marking along the length of the secondary ruler 2, that is, when the second standard surface 42 of the second sliding block 4 is aligned with the starting scale line of the second scale 21, the marking pen 6 is exactly at the starting point of the marking. With the above-mentioned structural design, the sliding distance of the second sliding block 4 on the secondary ruler 2 (that is, the size of the marking line applied by the marking pen 6 on the steel plate) can be easily read, thereby improving the work efficiency of the marking operation.

[0084] It should be noted that the thickness direction of the main ruler 1 is consistent with the thickness direction of the auxiliary ruler 2, and the thickness directions of both are arranged perpendicular to the plate surface to be marked.

[0086] In some embodiments, Figures 1 to 3 As shown, the main ruler 1 has a first top surface and a first bottom surface arranged opposite to each other along the thickness direction thereof, and a first scale 11 is arranged on the first top surface; the secondary ruler 2 has a second top surface and a second bottom surface arranged opposite to each other along the thickness direction thereof, and a second scale 21 is arranged on the second top surface; wherein the first bottom surface is arranged flush with the second bottom surface (that is, the first bottom surface and the second bottom surface are in the same plane), and the first bottom surface and the second bottom surface are in contact with the plate surface to be marked of the steel plate.

[0087] In this embodiment, the first scale 11 is arranged on the first top surface and the second scale 21 is arranged on the second top surface, which is conducive to the reading of the dimension data and convenient for operation. The first bottom surface and the second bottom surface are arranged to be flush with each other, so that the main scale 1 and the auxiliary scale 2 can be smoothly attached to the plate surface of the steel plate, ensuring the stability of the device after being placed on the steel plate, so as to facilitate the marking operation.

[0103] For reference Figures 1 to 3 as well as Figure 6 , Figure 1 A schematic diagram of a top view of a steel plate sampling and marking device provided in some embodiments of the present application; Figure 2 A schematic diagram of a three-dimensional structure of a main ruler provided in some embodiments of the present application; Figure 3 A schematic diagram of a three-dimensional structure of a secondary ruler provided in some embodiments of the present application; Figure 6 A schematic diagram of the three-dimensional structure of a fixing portion provided in some embodiments of the present application.

[0104] In some embodiments, Figure 1 and Figure 6 As shown, the steel plate sampling and marking device further includes a fixing portion 5, which is used to fix the main scale 1 and the secondary scale 2. The fixing portion 5 can be a bolt assembly or a welding point that fixes the main scale 1 and the secondary scale 2, or other connection structures that can fix the main scale 1 and the secondary scale 2, etc., which are not limited here.

[0105] For example, Figures 1 to 3 as well as Figure 6As shown, a specific structure of a fixing part 5 can be: the fixing part 5 includes a fixing screw 52 and a fixing block 51; a first through hole 511 and a second through hole 512 are opened on the fixing block 51, and the extension direction of the first through hole 511 is perpendicular to the extension direction of the second through hole 512; a first connecting plate 12 is arranged at one end where the main scale 1 is connected to the secondary scale 2, and the first connecting plate 12 is adaptively inserted in the first through hole 511, and the first connecting plate 12 and the first through hole 511 can be clearance-fitted; a second connecting plate 22 is arranged at one end where the secondary scale 2 is connected to the main scale 1, and the second connecting plate 22 is adaptively inserted in the second through hole 512, and the second connecting plate 22 and the second through hole 512 can be clearance-fitted; wherein, the first connecting plate 12 and the second connecting plate 22 at least partially overlap in the thickness direction of the fixing block 51, and the thickness direction of the fixing block 51 is consistent with the thickness direction of the main scale 1 and the thickness direction of the secondary scale 2. The fixing screw 52 is used to penetrate and fix the fixing block 51, the first connecting plate 12 and the second connecting plate 22, so as to realize the fixed connection between the main scale 1 and the secondary scale 2; specifically, a threaded hole compatible with the fixing screw 52 is opened on the fixing block 51, and a positioning hole is opened on the first connecting plate 12 and the second connecting plate 22 respectively. When the first connecting plate 12 and the second connecting plate 22 are assembled on the fixing block 51, the threaded hole on the fixing block 51 and the two positioning holes coincide with each other in the thickness direction of the fixing block 51. In this case, the fixing screw 52 is installed and the fixing screw 52 is penetrated through the threaded hole and the two positioning holes, so that the first connecting plate 12 can be locked in the first through hole 511 of the fixing block 51, and the second connecting plate 22 can be locked in the second through hole 512 of the fixing block 51, thereby realizing the fixed connection between the fixing block 51, the first connecting plate 12 and the second connecting plate 22.

[0106] Furthermore, the fixing part 5, the main ruler 1 and the auxiliary ruler 2 all have a bottom surface facing one side of the steel plate, and the bottom surfaces of the three are on the same plane; wherein, the bottom surface of the main ruler 1 is the first bottom surface in the above embodiment, and the bottom surface of the auxiliary ruler 2 is the second bottom surface in the above embodiment. With the above structural design, the bottom surfaces of the fixing part 5, the main ruler 1 and the auxiliary ruler 2 are set to a flush structure, so that the fixing part 5, the main ruler 1 and the auxiliary ruler 2 can be stably attached to the plate surface of the steel plate, ensuring the stability of the device after being placed on the steel plate, so as to facilitate the marking operation.

[0107] Furthermore, at least a portion of the bottom surfaces of the fixing portion 5, the main scale 1 and the auxiliary scale 2 are provided with a magnetic material layer 53. The magnetic material layer 53 can be adsorbed on the steel plate to ensure the fixation between the device and the steel plate during marking without causing marking deviation.

[0108] Optionally, the magnetic material layer 53 is provided only on the bottom surface of the fixing portion 5 .

[0110] One working step of the steel plate sampling and marking device of the present application is as follows:

[0111] 1) When sampling the steel plate, after knowing the width specification of the steel plate, determine the required sampling size and sampling position according to the standard; confirm the steel plate sampling position through the scale size on the main scale 1, and determine the sampling direction of the sample through the vertical relationship between the main scale 1 and the auxiliary scale 2.

[0112] 2) After confirming the sampling position, place the fixing part 5 near the starting sampling position, slide the first sliding block 3 to the position closest to the connection end, and make the marking pen 6 penetrating the first mounting hole 31 fall on the sampling position of the steel plate; through the magnetic material layer 53 at the bottom, the entire device can be adsorbed on the steel plate to avoid the deviation of the drawing caused by the change of the starting point during the marking process; according to the length of the sample, and at the same time read the sliding distance of the first sliding block 3 according to the first scale 11, drive the first sliding block 3 to slide on the main scale 1 until the sliding distance of the first sliding block 3 is consistent with the length of the sample; in this process, the marking pen 6 moves with the first sliding block 3 and can draw a length marking mark of the sample on the steel plate; wherein, when the first sliding block 3 slides into place, the first locking screw 35 can be used to temporarily fix the first sliding block 3 on the main scale 1.

[0113] 3) Slide the second sliding block 4 to the position closest to the connection end, and make the marking pen 6 with the second mounting hole 41 fall on the sampling position of the steel plate; according to the width of the sample, read the sliding distance of the second sliding block 4 according to the second scale 21, and drive the second sliding block 4 to slide on the secondary ruler 2 until the sliding distance of the second sliding block 4 is consistent with the width of the sample; in this process, the marking pen 6 moves with the second sliding block 4 and can draw a width marking mark of the sample on the steel plate; wherein, when the second sliding block 4 slides into place, the second locking screw 43 can be used to temporarily fix the second sliding block 4 on the secondary ruler 2.

[0114] 4) According to step 2) and step 3), the two side lines and three vertices in the quadrilateral of the sample can be determined, wherein one of the three vertices is a common vertex of the two side lines and the other two vertices are separate vertices. The device is moved to allow the marking pen 6 penetrating the first mounting hole 31 and the marking pen 6 penetrating the second mounting hole 41 to fall on two separate vertices respectively, and then the first sliding block 3 and the second sliding block 4 are unlocked and driven to move toward the connecting end successively, and the steel plate is marked again to form a closed quadrilateral, thereby completing the sampling size marking of the sample.

[0115] 5) According to the sample sampling quantity requirements, continue to repeat steps 1) to 4) to complete the sampling marking of the entire steel plate.
