Description

Technical Field

[0001] This utility model relates to the field of materials science and technology, and in particular to a sample fixing and bearing device for a continuous annealing simulation testing machine. Background Technology

[0002] Before a production process can be applied to large-scale production, conducting small-scale trials and verifications is an essential research step. Therefore, the experimental platform is an intermediate experimental carrier connecting laboratory research and development with large-scale production. Its core function is to verify the feasibility of the technology and optimize the production process through small-batch trial production, performance testing, and other processes.

[0003] Currently, a commonly used continuous annealing simulation testing machine on a testing platform includes a machine body and a specimen fixing and bearing device. The specimen fixing and bearing device includes two bearing bodies arranged side by side facing each other with a gap. The specimen is horizontally fixed to the two bearing bodies by screws for testing, and the specimen length is approximately equal to the distance between the two bearing bodies. However, this specimen fixing and bearing device can only fix specimens of one size according to the design specifications, such as a specimen length of 450mm, which limits the applicable specimen length range and affects the use of the continuous annealing simulation testing machine. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a specimen fixing and bearing device for a continuous annealing simulation test machine that is applicable to a wide range of specimen lengths.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a sample fixing bearing device for a continuous annealing simulation test machine, comprising two bearing bodies and multiple fasteners, the two bearing bodies are arranged side by side facing each other at intervals, a stepped bearing platform is provided on the bearing body, the stepped bearing platform includes multiple steps, the stepped bearing platform is arranged along the inner side to the outer side of the bearing body, and the height of the steps increases sequentially along the inner side to the outer side of the bearing body.

[0006] Each step is equipped with a fixing groove, which is arranged along the length of the step. Fasteners can be used to detachably place the sample on any step of the stepped support platform through the fixing groove.

[0007] Furthermore, the stepped support platform includes 10-15 steps.

[0008] Furthermore, the fixing groove is a threaded groove, and the fastener is a screw.

[0009] Furthermore, each step has 3-5 fixed slots.

[0010] Furthermore, the sample is placed horizontally on any step.

[0011] Furthermore, baffles are installed on both sides of the stepped support platform. The baffles are vertically arranged and perpendicular to the length direction of the steps.

[0012] Furthermore, the support body is provided with multiple mounting holes, which are located on the outside of the stepped support platform.

[0013] Furthermore, the mounting hole is a threaded hole.

[0014] The beneficial effects of this utility model are as follows: By setting a stepped support platform on the support body, the stepped support platform includes multiple steps, which are arranged from the inner side to the outer side of the support body. The height of the steps increases sequentially from the inner side to the outer side of the support body. Each step is provided with a fixing groove, which is arranged along the length of the step. Fasteners can detachably and horizontally place the sample on any step of the stepped support platform through the fixing groove. Steps at different positions can fix samples of different lengths, so that samples of different lengths can be tested. This significantly improves the applicable sample length range of the continuous annealing simulation test machine and increases the test efficiency. Furthermore, the sample fixing support device has a simple structure, is easy to manufacture, and is suitable for large-scale use. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a sample fixing and bearing device for a continuous annealing simulation test machine, comprising two bearing bodies 1 and multiple fasteners 2. The two bearing bodies 1 are arranged side by side facing each other at intervals. A stepped bearing platform 11 is provided on the bearing body 1. The stepped bearing platform 11 includes multiple steps 111. The stepped bearing platform 11 is arranged along the inner side to the outer side of the bearing body 1, and the height of the steps 111 increases sequentially along the inner side to the outer side of the bearing body 1.

[0021] Each step 111 is provided with a fixing groove 112, which is arranged along the length of the step 111. The fastener 2 can detachably place the sample 4 on any step 111 of the stepped support platform 11 through the fixing groove 112.

[0022] The inner side of carrier 1 refers to the side where the two carriers 1 are closer together, and the outer side of carrier 1 refers to the side where the two carriers 1 are farther apart. Figure 1 The side located in the middle of the support body 1 is the inner side of the support body 1. Figure 2 The right side of the middle support 1 is the inner side, and the left side of the middle support 1 is the outer side.

[0023] The sample 4 is typically rectangular or square in shape. The support body 1 primarily supports the sample 4. The sample 4 is horizontally positioned on the steps 111 of the stepped support platform 11. For example: Figure 1 As shown, the left half of the sample 4 is fixed on the step 111 of the left support platform 11, and the right half of the sample 4 is fixed on the step 111 of the right support platform 11. The steps 111 at different positions can fix samples 4 of different lengths for testing, which significantly improves the applicable sample 4 length range of the continuous annealing simulation test machine and improves the test efficiency.

[0024] To ensure the strength of the bearing 1, the bearing 1 is preferably made of steel, with the following specific parameters: overall hardness between 40-48 HRC, quenched martensite level ≤ 2, curvature of the plane and side surface ≤ 0.1 mm, and carburized layer depth: 0.15-0.18 mm.

[0025] To ensure the effectiveness of the stepped support platform 11, for example... Figure 1 , Figure 3 As shown, the stepped support platform 11 preferably includes 10-15 steps 111, each step 111 having a width of 20mm and a height of 10mm. Since the height of the steps 111 increases sequentially from the inside to the outside of the support body 1, the length of the applicable sample 4 also increases sequentially from the inside to the outside of the support body 1.

[0026] To facilitate the installation and disassembly of sample 4 and ensure the effectiveness of fastener 2, fastener 2 is a screw. The fixing groove 112 is preferably a threaded groove, meaning the inner wall of the groove is threaded, and the thread of the groove matches the thread of the screw. The number of fasteners 2 and fixing grooves 112 depends on the length of step 111. Preferably, each step 111 has 3-5 fixing grooves 112, corresponding to 3-5 screws, with one screw matching one fixing groove 112.

[0027] To reduce the possibility of slippage and detachment of sample 4 during retesting, for example... Figure 2As shown, baffles 3 are respectively provided on both sides of the stepped support platform 11. The baffles 3 are arranged vertically and are perpendicular to the length direction of the step 111.

[0028] The carrier 1 can be directly mounted on the body of the continuous annealing simulation testing machine, for example... Figure 1 As shown, multiple mounting holes 12 are provided on the support body 1. The mounting holes 12 are threaded holes and are located on the outer side of the stepped support platform 11. The orientation of the mounting holes 12 is consistent with the orientation of the fixing groove 112. Screws or bolts are inserted into the mounting holes 12 and the connecting holes on the machine body to detachably fix the support body 1 to the machine body of the continuous annealing simulation testing machine. However, some continuous annealing simulation testing machines have an original sample fixing support platform installed on the machine body. To ensure the installation of the support body 1, for example... Figure 2 As shown, the bottom of the carrier 1 is provided with a clearance notch 13, the mounting hole 12 is provided above the clearance notch 13, the original sample fixing carrier platform is provided at the clearance notch 13, and a connecting hole is provided on the upper surface of the original sample fixing carrier platform. Screws or bolts are inserted into the mounting hole 12 and the connecting hole on the original sample fixing carrier platform to detachably fix the carrier 1 to the body of the continuous annealing simulation test machine.
