Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical detection, and specifically relates to a hardness testing device for metallurgical detection. Background Art

[0002] A hardness testing device for metallurgical detection refers to a device used to measure the hardness of metals or other materials. Such a device usually includes an indenter or a drill bit, which leaves an indentation or performs surface cutting on the material surface by applying a certain force or pressure. Then, based on the size of these indentations or the reaction of the material, the hardness value of the material can be inferred, which is very important for material quality control and performance evaluation;

In this patent, it is recorded that by starting the control panel, the stepping motor in the lower frame is started, the hydraulic rod is driven by the bottom pump to rise to press the test piece under the indenter, the hardness of the test piece is detected by the upper frame on the indenter, and at the same time, the water-cooled diversion pipe in the external cooler dissipates heat and conducts heat to the stepping motor in the lower frame. The heat is introduced into the external cooler through the water-cooled diversion pipe, the stepping motor drives the cooling fan to rotate to conduct the heat into the air under the upper air guide fan, and at the same time, the stepping motor drives the lower guide rod to rotate, then the lower guide rod drives the upper connecting rod to rotate, the upper connecting rod drives the upper air guide fan to rotate, and finally the upper air guide fan guides the hot air to the outside of the external cooler through the upper air guide opening, so as to ensure that the internal hardness detection device can be detected at a constant temperature and prevent equipment damage caused by excessive internal temperature;

[0004] In this solution, although the temperature generated during detection can be effectively reduced, the device detects the hardness by the degree of bending of the workpiece. Since the bending degree is different at different positions during bending, the device cannot bend the workpiece at different positions, resulting in too limited and inaccurate bending data. To solve this technical problem, the utility model proposes a hardness testing device for metallurgical detection. Summary of the Invention

Detailed Embodiment

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0025] Example 1: A hardness testing device for metallurgical testing, including a support base 1 and a metallurgical part body 4. Two pairs of symmetrically arranged legs 2 are fixedly connected to the bottom of the support base 1. An adjusting mechanism 6 is fixedly connected to the outer wall of the support base 1. The adjusting mechanism 6 includes a connecting frame 601, a threaded rod 603, a connecting block 604, an electro-hydraulic rod 607 and a hard pressing plate 608. The connecting frame 601 is fixedly connected to the outer wall of the support base 1. At the same time, the hard pressing plate 608 is fixedly connected to the output end of the electro-hydraulic rod 607, and the hard pressing plate 608 is located above the metallurgical part body 4. The outer wall of the other end of the connecting frame 601 is fixedly connected with a motor 602. The threaded rod 603 is fixedly connected to the output end of the motor 602. At the same time, the threaded rod 603 is rotatably connected inside the connecting frame 601. The connecting block 604 is threadedly connected to the outer wall of the threaded rod 603. A chute 605 is provided inside the connecting frame 601. The chute 605 corresponds to the connecting block 604. At the same time, the connecting block 604 is slidably connected inside the chute 605. The outer wall of the connecting block 604 is fixedly connected with a connecting plate 606. And the electro-hydraulic rod 607 is fixedly connected to the outer wall of the connecting plate 606. Two positioning rods 609 are fixedly connected to both sides of the top of the hard pressing plate 608. At the same time, limiting blocks 610 are fixedly connected to the outer walls of both sides of the connecting plate 606. And the positioning rods 609 pass through the limiting blocks 610 and are slidably connected inside the limiting blocks 610.

[0026] By starting the motor 602 on the outer wall of the connecting frame 601, the motor 602 drives the threaded rod 603 to rotate. The rotation of the threaded rod 603 drives the connecting block 604 to move left and right in the chute 605 to ensure that the moving direction of the connecting plate 606 is consistent. The movement of the connecting plate 606 is controlled by the electro-hydraulic rod 607. The start of the electro-hydraulic rod 607 causes the hard pressing plate 608 to move downward for detecting and analyzing the hardness of the metallurgical part body 4. When the hard pressing plate 608 moves downward, it is limited by the positioning rods 609 to ensure that its moving direction is accurate and consistent. These operations cooperate to achieve precise detection of different positions of the metallurgical part body 4, significantly improving the working efficiency and the accuracy of the test.

[0027] Embodiment 2: The difference between this embodiment and Embodiment 1 is that a fixing mechanism 3 is provided on the top of the support base 1. The fixing mechanism 3 includes a nut 301, a threaded support rod 302, a lower pressing plate 304, a cylinder 305 and an upper pressing plate 307. At the same time, the nut 301 is fixedly connected inside the support base 1, and the lower pressing plate 304 is fixedly connected to the top of the threaded support rod 302. At the same time, the metallurgical part body 4 is arranged between the upper pressing plate 307 and the lower pressing plate 304. The threaded support rod 302 is threadedly connected inside the nut 301. At the same time, the threaded support rod 302 penetrates through the support base 1 and extends to the inside of the support base 1. A turning handle 303 is fixedly connected to the outer side wall of the threaded support rod 302. The cylinder 305 is fixedly connected to the top of the support base 1. The output end of the cylinder 305 is fixedly connected to a connecting column 306. At the same time, the upper pressing plate 307 is fixedly connected to the bottom end of the connecting column 306, and the upper pressing plate 307 corresponds to the lower pressing plate 304. A control console 5 is arranged on the outer surface above the support base 1.

[0028] By rotating the turning handle 303, the threaded support rod 302 is driven to rotate, and the nut 301 restricts its rising position. As the threaded support rod 302 rises, the lower pressing plate 304 also rises accordingly. When the lower pressing plate 304 rises to a certain height, the metallurgical part body 4 can be placed on its top. Then, the cylinder 305 is operated through the control console 5 to make the connecting column 306 move downward, and at the same time drive the upper pressing plate 307, so as to firmly fix the metallurgical part body 4.

[0029] Working principle: When the staff needs to perform a hardness test on the metallurgical part body 4, first rotate the handle 303. The rotation of the handle 303 drives the threaded support rod 302 to rotate. The threaded support rod 302 is limited by the nut 301, so the threaded support rod 302 gradually rises when rotating, and drives the lower pressing plate 304 to move up and down. When the lower pressing plate 304 rises into the air, then place the metallurgical part body 4 on the top of the lower pressing plate 304. Under the control of the console 5, start the cylinder 305 to drive the connecting column 306 to move down, and drive the upper pressing plate 307 to move down to fix the metallurgical part body 4. After the fixation is completed, start the motor 602 on the outer wall of the connecting frame 601. Under the action of the motor 602, drive the rotation of the threaded rod 603. When the threaded rod 603 rotates, it will drive the connecting block 604 to move left and right. At this time, the connecting block 604 will drive the connecting plate 606 to move left and right, and the connecting block 604 is limited in the chute 605, so as to ensure that the moving direction of the connecting plate 606 is consistent. When the connecting plate 606 moves, it will drive the electro-hydraulic rod 607 to move left and right. At this time, start the electro-hydraulic rod 607 to drive the hard pressing plate 608 to move down, and detect the hardness of the metallurgical part body 4 through the hard pressing plate 608. Analyze according to the bending degree of different positions of the metallurgical part body 4. When the hard pressing plate 608 moves down, it is limited in the limiting block 610 by the positioning rod 609, so as to ensure that the moving direction of the hard pressing plate 608 is consistent. Through their cooperation, the detection of different positions of the metallurgical part body 4 is realized, and the work efficiency and accuracy are improved.
