Description

Technical Field

[0001] This application relates to the field of tensile equipment technology, specifically a tensile testing machine for alloy products. Background Technology

[0002] Alloy products are a new type of metallic material composed of a mixture of multiple metallic elements, and are widely used in aerospace, automotive, electronics and other fields.

[0003] During the production of alloy products, tensile tests are required to evaluate the mechanical properties, process stability, and practical application feasibility of the alloy materials. This ensures that the materials meet the requirements in material research and development, manufacturing, and practical applications. In the prior art, tensile testing machines are commonly used to perform tensile tests on alloy products. For example, Chinese utility model patent CN213422783U discloses an aluminum alloy tensile testing machine. This patent uses a fixed block at the left end of the mounting plate and a clamping block at the lower end of the fixed block. When the clamping device is used for tensile testing, the clamping block slides on the inclined surface of the fixed block, preventing the profile from sliding relative to the fixed block during the tensile process and making the clamping more stable.

[0004] However, in the implementation of the above technical solution, since the clamping parts and the fixing blocks are fixedly set, tensile tests can usually only be performed on alloy parts of the same type. When faced with alloy parts of different types, the above technical solution is difficult to apply and has low adaptability.

[0005] Therefore, it is necessary to provide a tensile testing machine for alloy products to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide an alloy product tensile testing machine, which makes it convenient to replace the clamping blocks in the clamping mechanism when performing tensile tests on different types of alloy products by making the clamping blocks detachable.

[0008] The technical solution adopted by this application to solve its technical problem is: a tensile testing machine for alloy products, comprising:

[0009] Base;

[0010] The columns are arranged in pairs;

[0011] A crossbeam, which is fixed to the top of the column;

[0012] A drive component, wherein the drive component is disposed on the base;

[0013] A tensioning assembly, which is connected to a driving assembly via a transmission connection;

[0014] The stretching component includes:

[0015] A tension plate, which is slidably disposed between the columns, and the tension plate and the crossbeam form a tensile test area;

[0016] Clamping mechanisms are arranged in pairs, respectively mounted on the crossbeam and the tension plate;

[0017] The clamping mechanism includes:

[0018] The fixing block is fixedly installed on the tension plate;

[0019] The movable groove has an opening whose width is smaller than the width of other locations;

[0020] Clamping blocks, which are slidably disposed in pairs within the movable groove;

[0021] A stop block, which is detachably mounted on a fixed block.

[0022] In the implementation of the technical solution of this application, by setting a clamping block and sliding the clamping block in the movable groove, and setting a detachable stop block to longitudinally block the clamping block, it is convenient to quickly replace the clamping block when tensile tests are required on different types of alloy materials, without having to replace the entire equipment.

[0023] Furthermore, the bottom of the clamping block is provided with a mounting groove, in which a mounting block is installed, and a toothed rack is provided on the side of the mounting block;

[0024] Furthermore, a half-gear is hinged to the fixing block, which meshes with a rack on the side of the mounting block, and the half-gear is connected to a handle.

[0025] Furthermore, the drive assembly includes a motor fixed on the base, and the output end of the motor is connected to a pulley assembly, which is connected to a pair of lead screws. The two ends of the pair of lead screws are respectively connected to the base and the crossbeam bearing, and the tension plate is disposed on the lead screws.

[0026] Furthermore, the clamping mechanism also includes a mounting post, which is fixed to the tension plate.

[0027] The beneficial effects of this application are: the alloy product tensile testing machine provided by this application is equipped with clamping blocks and slides the clamping blocks in the movable groove. At the same time, a detachable stop block is set to longitudinally block the clamping blocks. When tensile tests are required on different types of alloy materials, it is convenient to quickly replace the clamping blocks without replacing the entire equipment.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0038] like Figure 1As shown, this application provides a tensile testing machine for alloy products. This tensile testing machine is used to perform tensile tests on alloy products to evaluate the mechanical properties, process stability and practical application possibilities of alloy materials. The tensile testing machine includes a base 1, which serves as a support. A pair of columns 2 are arranged on the base 1 and are fixedly connected to the base 1. There is a certain space between the pair of columns 2. A crossbeam 3 is fixedly installed on the top of the columns 2. A drive assembly 4 is also provided on the base 1. A tensile assembly 5 is arranged in the space between the columns 2. The drive assembly 4 is connected to the tensile assembly 5 for transmission and controls the tensile assembly 5 through the drive assembly 4.

[0039] like Figure 2 As shown, the drive assembly 4 includes a motor 41, which is fixed on the base 1. The output end of the motor 41 is connected to a pulley assembly 42, which is connected to a pair of lead screws 43. The two ends of the pair of lead screws 43 are respectively connected to the bearings of the base 1 and the crossbeam 3. Under the drive of the motor 41 and the pulley assembly 42, the lead screws 43 can rotate.

[0040] The tensioning assembly 5 includes a tensioning plate 51, which is threadedly connected to the lead screw 43. When the lead screw 43 is driven to rotate, the tensioning plate 51 can move along the length direction of the lead screw 43, thereby changing the distance between the tensioning plate 51 and the crossbeam 3.

[0041] The space formed between the crossbeam 3 and the tension plate 51 serves as the tensile test area. In order to fix the alloy product to be tested, a clamping mechanism 52 is provided on both the crossbeam 3 and the tension plate 51. The two clamping mechanisms 52 are arranged opposite each other. During the tensile test, the two ends of the alloy product are fixed by the clamping mechanism 52, and then the screw 43 is driven to rotate by the motor 41. During the rotation of the screw 43, the tension plate 51 will move towards or away from the crossbeam 3, thereby performing a tensile test on the alloy product in the tensile test area.

[0042] like Figures 3-4As shown, the clamping mechanism 52 includes a mounting post 521, which is fixed to the tension plate 51. A fixing block 522 is fixedly disposed inside the mounting post 521. The fixing block 522 has a movable groove 523 with an opening. The width of the opening is smaller than the width of other parts of the movable groove 523, and the side of the movable groove 523 is inclined, making the entire movable groove 523 V-shaped. A pair of clamping blocks 524 are slidably disposed inside the movable groove 523, and the pair of clamping blocks 524 are adapted to clamp the movable groove. The sliding mechanism 523 slides within the groove, and during the sliding process, the distance between the pair of clamping blocks 524 changes due to the pressure from the inclined surface of the movable groove 523. Specifically, when the clamping blocks 524 move toward the opening direction, since the width of the opening is smaller than the width of other positions of the movable groove 523, the pair of clamping blocks 524 are pressed by the inclined surface and thus move closer to each other, achieving the clamping function of the alloy product. When the clamping blocks 524 move away from the opening direction, the pair of clamping blocks 524 move away, thereby releasing the clamping of the alloy product.

[0043] It should be noted that an inclined surface matching the inclined surface of the side of the movable groove 523 is provided on the outer side of the clamping block 524, so that when the clamping block 524 slides in the movable groove 523, the central clamping position can be kept on the same axis.

[0044] In order to control the movement of clamp 524, such as Figures 3-4 As shown, the bottom of the clamping block 524 is provided with a mounting groove 525, and a mounting block 526 is provided in the mounting groove 525. The mounting block 526 is slidably disposed in the mounting post 521, and the top of the mounting block 526 has a protrusion that is inserted into the mounting groove 525. By simply moving the mounting block 526, the clamping block 524 can be moved.

[0045] The mounting block 526 has a rack 527 on its side, and a half gear 528 is hinged to the fixing block 522. The half gear 528 meshes with the rack 527 on the side of the mounting block 526, and the half gear 528 is connected to a handle 529. In use, by rotating the half gear 528 through the handle 529, the mounting block 526 can be moved, which in turn controls the movement of the clamping block 524, thereby achieving the clamping of the alloy product.

[0046] Because alloy products come in different sizes, matching clamping components are usually required when performing tensile tests. Therefore, to facilitate replacement, a stop block 530 is provided on the fixing block 522. The stop block 530 can fix the clamping block 524 to prevent it from falling or shifting during movement. The stop block 530 is provided with a bolt 531, which fixes the stop block 530 to the fixing block 522. When tensile tests are required on different types of alloy products, simply unscrew the bolt 531, remove the stop block 530, and the clamping block 524 can be taken out and replaced. It has strong adaptability and does not require replacing the entire equipment.

[0047] The clamping mechanism 52 on the crossbeam 3 has the same structure as the clamping mechanism 52 on the tension plate 51, so it will not be described again in this embodiment.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
