Description

Technical Field

[0001] This utility model relates to the field of large plate bending detection technology, specifically to an adjustable detection template for assisting in the bending detection of large plates. Background Technology

[0002] When producing plate parts for large trough-type equipment such as scraper conveyors and intermediate troughs used in underground coal mines, the cut steel plates (large plates) need to be placed on a thousand-ton press. The upper and lower dies of the press apply pressure to the steel plates, gradually shaping them into the required arc dimensions. During this arc-pressing process, real-time control of the steel plate's arc is crucial. Therefore, frequent measurements using a bending test template are necessary to determine whether the pressed steel plate has reached the predetermined arc standard.

[0003] Traditional bending test templates are relatively simple in construction, mainly consisting of a base plate and a steel plate with a fixed arc shape welded together, making them fixed-style testing tools. However, in actual production scenarios, different types of equipment use plate parts with varying bending requirements. This means that to meet the production needs of various curved steel plates, companies have to manufacture a large number of test templates with different arc standards. This increases the production cost of the test templates. Furthermore, numerous test templates of different specifications occupy a significant amount of storage space during production. In actual use, workers must frequently move and exchange these test templates whenever they switch to test plate parts with different bending degrees. This process not only consumes manpower and resources but also seriously affects production efficiency, causing great inconvenience to actual production operations. Utility Model Content

[0004] In view of this, it is necessary to provide an adjustable test template for assisting in the detection of the curvature of large plates, so as to solve the technical problem of frequent handling and replacement of test templates in the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An adjustable testing template for assisting in the detection of curvature of large sheet metal includes a long, narrow template base, an adjusting rod, a positioning slide rod, and a pre-defined curvature detection component capable of elastic deformation. The side walls of the template base have opposing through-grooves extending along the length of the template base and parallel to it. A receiving groove is formed on the front of the template base, also extending along the length of the template base, perpendicular to and connected to the slide grooves. Two positioning slide rods are respectively inserted into the slide grooves and can slide freely along the opening direction of the slide grooves. The curvature detection component is movably disposed in the receiving groove. The two ends of the measuring element face the two ends of the receiving groove and are respectively connected to the two positioning slide rods in the groove. The two positioning slide rods restrict the two ends of the curvature detection element in the receiving groove. The adjusting rod is threadedly connected to the back of the template base and is directly opposite the center of the receiving groove. One end of the adjusting rod passes through the template base and abuts against the center of the back of the curvature detection element in the receiving groove. By rotating the adjusting rod towards the receiving groove, the middle part of the curvature detection element can be pushed out of the receiving groove, causing the curvature detection element to deform and form an arc with a preset chord height on the front of the template base. The curvature of the large plate is detected by using the arc state of the deformed curvature detection element.

[0007] Preferably, the two positioning slide rods are respectively provided with slots for inserting the ends of the curvature detection component at the positions opposite to the receiving groove. Locking bolts that penetrate the slots are provided on the outer side walls of the slots. The two ends of the curvature detection component are respectively detachably inserted into the slots on the two positioning slide rods and locked and fixed by the locking bolts.

[0008] Preferably, one end of each of the two positioning slide rods is provided with a threaded positioning bolt, and the other end of each of the two positioning slide rods is provided with a stop head. The stop head and the positioning bolt respectively stop on the slide groove ports on both sides of the template base. By rotating the positioning bolt, the positioning slide rod can be locked in the slide groove.

[0009] Preferably, the arc detection element is a long, highly elastic steel bar or steel plate of a preset length.

[0010] Preferably, the adjusting rod is a threaded rod, and a handle is provided at the end of the adjusting rod away from the template base.

[0011] Preferably, the adjusting rod is also threadedly connected to a locking bolt, which can be pressed tightly against the back of the template base to lock the adjusting rod.

[0012] As can be seen from the above technical solution, the adjustable testing template for assisting in the detection of the curvature of large plates provided in this application has sliding grooves through both sides of the template base and a receiving groove on the front of the template base. The curvature detection component is movably placed in the receiving groove, with both ends of the curvature detection component facing the two ends of the receiving groove and respectively connected to two positioning sliding rods in the sliding groove. The adjusting rod passes through the receiving groove from the back of the template base and abuts against the center of the back of the curvature detection component. By rotating the adjusting rod, the middle part of the curvature detection component is pushed out of the receiving groove, so that the curvature detection... The test piece forms an arc with a preset chord height on the front of the template base. Its advantages are: the adjustable test template can be flexibly adjusted according to the test requirements, and can detect the curvature of large plates of different models. It realizes multiple uses of one machine, reduces the production cost of enterprises, avoids the trouble of frequent handling and replacement, saves manpower, makes the test work more convenient, and improves production efficiency. In addition, after the test is completed, the adjusting rod can be removed, so that the arc test piece can retract into the receiving groove under its own deformation force, reducing the space occupied and facilitating handling and storage.

[0019] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0020] Please refer to Figure 1 , Figure 2 and Figure 5 This utility model provides an adjustable testing template for assisting in the detection of the curvature of large plates. It includes a long, narrow template base 10, an adjusting top rod 20, a positioning slide rod 30, and a pre-defined curvature detection component 40 capable of elastic deformation. The template base 10 has opposing through-grooves 11 on both sides of its sidewalls. These grooves 11 extend along the length of the template base 10 and are parallel to it. A receiving groove 12 is provided on the front of the template base 10. This receiving groove 12 also extends along the length of the template base 10, is perpendicular to the grooves 11, and is interconnected with them. The positioning slide rod 30... Two 0s are respectively inserted into the slide groove 11 and can slide freely along the opening direction of the slide groove 11. The arc detection element 40 is movably disposed in the receiving groove 12, with its two ends facing the two ends of the receiving groove 12 and respectively inserted into the slide groove 11 from the receiving groove 12. It is connected to the two positioning slide rods 30 in the slide groove 11, and the positioning slide rods 30 are perpendicular to the arc detection element 40. The two positioning slide rods 30 restrict the two ends of the arc detection element 40 in the receiving groove 12, so that it cannot be removed from the receiving groove 12. The adjusting top rod 20 is vertically threadedly connected to the template base 10. The back of the sample base 10 is directly opposite the center of the receiving groove 12. One end of the adjusting rod 20 passes through the template base 10 and rests against the center of the back of the arc detection component 40 in the receiving groove 12. By manually rotating the adjusting rod 20, it can pass through the receiving groove 12 and move upward toward the front of the template base 10. This allows the middle part of the arc detection component 40 to be pushed out of the receiving groove 12. The arc detection component 40 is a long steel bar or steel plate made of high-elasticity spring steel. Since both ends of the arc detection component 40 are confined in the receiving groove 12, the middle part is pushed out by the force of the adjusting rod 20. During the process of receiving the sample in the groove 12, the two positioning slide rods 30, under the pulling force at both ends of the curvature detection component 40, can slide adaptively in opposite directions along the slide groove 11. This allows the two ends of the curvature detection component 40 to move closer to each other along the receiving groove 12, causing the middle part of the curvature detection component 40 to deform and form an arc shape on the front of the template base 10. During testing, the curvature of the curvature detection component 40 can be adjusted by adjusting the top rod 20 until it reaches a curvature corresponding to the curvature of the large plate to be tested. Then, the sample base 10 can be moved together to test the curvature of the large plate. The testing method is the same as that of traditional curvature testing templates. After the testing is completed, the adjusting top rod 20 can be removed. After the adjusting top rod 20 is removed, the curvature detection component 40 can retract into the receiving groove 12 under its own deformation force, thus reducing the space occupied and facilitating transportation and storage.

[0021] Please refer to Figure 1 , Figure 4 and Figure 5Furthermore, to facilitate the replacement of curvature detection components 40 of different lengths, slots 31 for inserting the ends of the curvature detection components 40 are respectively provided at the positions of the two positioning slide rods 30 opposite to the receiving groove 12. The two ends of the curvature detection component 40 can be detachably inserted into the slots 31 on the two positioning slide rods 30 by means of interference fit. In order to improve the stability of the connection, locking bolts 32 are also provided on the outer wall of the slot 31, which penetrate the slot 31. After the two ends of the curvature detection component 40 are inserted into the slot 31, they can be locked and fixed by the locking bolts 32. When detecting the curvature of different large plates, the curvature detection component 40 of matching length can be replaced according to the actual detection requirements.

[0022] Please continue reading. Figure 1 , Figure 4 and Figure 5 Furthermore, to improve the stability of the curvature detection component 40 when detecting the curvature of large plates, a positioning bolt 33 is provided at one end of each of the two positioning slide rods 30, and a stop head 34 is provided at the other end of each of the two positioning slide rods 30. The positioning bolt 33 is threadedly connected to the positioning slide rod 30. The diameters of the stop head 34 and the positioning bolt 33 are both larger than the width of the slide groove 11. The stop head 34 and the positioning bolt 33 stop on the slide groove 11 ports on both sides of the template base 10. When adjusting the chord height of the curvature detection component 40, the positioning bolt 33 can be loosened so that the positioning slide rod 30 can slide along the slide groove 11. After the chord height of the curvature detection component 40 is adjusted, the positioning bolt 33 is locked by rotating it. The positioning bolt 33 and the stop head 34 form a clamping force to lock the positioning slide rod 30 in the slide groove 11 and prevent it from moving. By locking the position of the positioning slide rod 30, the two ends of the curvature detection component 40 can be effectively fixed.

[0023] Please refer to Figure 3 and Figure 5 In the above embodiment, the adjusting rod 20 is a threaded rod, and a handle 21 is provided at the end of the adjusting rod 20 away from the template base 10. By rotating the handle 21, the chord height of the curvature detection component 40 can be adjusted. A locking bolt 22 is also threadedly connected to the adjusting rod 20. The locking bolt 22 is located on the back of the template base 10. After the chord height of the curvature detection component 40 is adjusted, the locking bolt 22 is rotated separately to press it tightly against the back of the template base 10. The locking bolt 22 applies a reverse force to the adjusting rod 20 to lock the adjusting rod 20 onto the template base 10, preventing the adjusting rod 20 from loosening during the process of detecting the curvature of large plates.

[0024] In the above embodiments, the curvature detection element 40 is made of spring steel, which has high elasticity. The thickness or diameter of the curvature detection element 40 is uniform, and the force exerted by the adjusting rod 20 is always less than the critical value that causes it to undergo plastic deformation. Thus, when the adjusting rod 20 pushes the curvature detection element 40 toward the front of the template base 10, it can be ensured that the curvature detection element 40 undergoes elastic deformation. After the adjusting rod 20 descends, the curvature detection element 40 will retract into the housing under its own deformation force.

[0025] This adjustable testing template allows for the replacement of a curvature testing piece 40 of the appropriate length to test the curvature of large plates of different models, based on actual testing requirements. During adjustment, the curvature testing piece 40 is pushed out to the desired chord height by adjusting the top rod 20. Then, the positioning bolt 33 is rotated to lock the positioning slide rod 30 in the slide groove 11, thus locking the chord length between the two ends of the curvature testing piece 40. By locking the chord height and chord length of the curvature testing piece 40, the desired curvature can be obtained.

[0026] This adjustable testing template can be flexibly adjusted according to testing needs, enabling the testing of the curvature of large plates of different models. It achieves multiple uses in one machine, reduces enterprise production costs, avoids the trouble of frequent handling and replacement, saves manpower, makes the testing work more convenient, and improves production efficiency. Furthermore, after the adjustable testing template is used, the adjusting rod 20 can be removed, and the curvature testing part 40 can retract into the receiving groove 12 under its own deformation force, which can reduce the space occupied and facilitate handling and storage.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
