Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal material testing technology, specifically a metal material testing device. Background Technology
[0002] Metal hardness testing is the fastest, most economical, and simplest test method for evaluating the mechanical properties of metals. The main purpose of hardness testing is to determine the suitability of a material, or the effect of special hardening or softening treatments applied to the material for its intended use.
[0003] For example, a metal material hardness testing device and method with application publication number "CN119819593A" uses two third belt drives, in conjunction with a conveyor belt, to rotate four conveyor rollers. The conveyor belt itself also rotates, carrying the metal material at the top. As the metal material passes the bottom of the cleaning rollers, the cleaning rollers, driven by the output shaft of a fifth motor, clean the dust from the surface of the metal material. However, this device uses multiple conveyor belts and other structures to transport the metal material, making it inconvenient to handle during use. Since the device may be used in different scenarios or locations for testing metal materials, its inconvenience in handling leads to its overall inconvenience. Utility Model Content
[0004] The purpose of this invention is to solve the problem of inconvenience in using the device, and to propose a metal material testing device.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] Design a metal material testing device, including a base and support legs. The lower end of the base is fixedly connected to multiple support legs, and the upper end of the base is provided with a support structure. The upper end of the base is fitted with a frame, and the inner wall of the frame is provided with multiple sets of adjustment structures. The upper end of the base is symmetrically provided with dovetail grooves, and the upper end of the frame is fixedly connected with a handle.
[0007] Preferably, the support structure includes a dovetail block and a support plate, the lower end of the support plate is fitted with the base, the lower end of the support plate is symmetrically and fixedly connected with the dovetail block, and the upper end of the support plate is provided with a groove.
[0008] Preferably, the surfaces of the dovetail blocks on both sides are slidably connected to the dovetail grooves on both sides.
[0009] Preferably, a Leeb hardness tester is fixedly connected to the inner wall of the frame.
[0010] Preferably, the adjustment structure includes through-hole blocks and sliding rods. One end of the two through-hole blocks is fixedly connected to the frame, and the two through-hole blocks on both sides are slidably connected to the sliding rods through through-holes on their surfaces. The surface of the sliding rods is abutted against bolts.
[0011] Preferably, the outer wall of the bolt is threaded to the frame, and one end of the bolt penetrates the frame.
[0012] The present invention discloses a metal material testing device with the following advantages: By adjusting the coordination of the structure and the support structure, when testing larger metal materials, the operator rotates four bolts so that one end of the bolts is no longer pressed against the surface of the four sliding rods. The operator then pulls the handle upwards, causing the handle to slide through the frame onto the surface of the eight through-hole blocks on the sliding rods. This allows the frame to move the Leeb hardness tester upwards, enabling the Leeb hardness tester probe to adjust the distance between itself and the support plate surface. After adjustment, the four bolts are tightened again to fix the position of the frame. Simultaneously, the support plate can be pulled, causing the dovetail blocks on both sides to slide out of the base, facilitating the removal and cleaning of the support plate. This allows for adjustment of the device and makes it easy to hold, making the device more convenient to use. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:
[0021] See attached document Figure 1-6 In this embodiment, a metal material detection device includes a base 1 and support legs 6. Multiple support legs 6 are fixedly connected to the lower end of the base 1, and a support structure 8 is provided at the upper end of the base 1. The upper end of the base 1 is attached to the frame 3. Multiple sets of adjustment structures 2 are provided on the inner wall of the frame 3. Dovetail grooves 7 are symmetrically opened at the upper end of the base 1, and a handle 4 is fixedly connected to the upper end of the frame 3.
[0022] The surfaces of the dovetail blocks 801 on both sides are slidably connected to the dovetail grooves 7 on both sides. The inner wall of the frame 3 is fixedly connected to the Leeb hardness tester 5. The outer wall of the bolt 201 is threadedly connected to the frame 3. One end of the bolt 201 passes through the frame 3.
[0023] The support structure 8 includes a dovetail block 801 and a support plate 802. The lower end of the support plate 802 is attached to the base 1. The dovetail block 801 is symmetrically fixedly connected to the lower end of the support plate 802. A groove is provided at the upper end of the support plate 802.
[0024] The adjustment structure 2 includes through-hole blocks 202 and slide rods 203. One end of the two through-hole blocks 202 is fixedly connected to the frame 3, and the two through-hole blocks 202 on both sides are slidably connected to the slide rods 203 through through-holes opened on the surface. The surface of the slide rods 203 is pressed against the bolts 201.
[0025] Working principle:
[0026] When testing the hardness of metallic materials:
[0027] The operator moves the device by lifting it with handle 4, allowing it to be transported to the designated location. The operator places the metal material into the groove on the surface of the tray 802 and controls the Leeb hardness tester 5 to operate. The Leeb hardness tester 5 can be model LS252D. The probe of the Leeb hardness tester 5 impacts the metal material. The punch (usually a diamond or tungsten carbide ball head) inside the impact device impacts the sample surface at a fixed speed (Vi) under the action of spring force, and then rebounds to a distance of 1mm from the surface. At this time, the rebound speed is Vr. The punch has a built-in magnet, and the voltage generated during the impact and rebound is sensed by the coil, thereby accurately calculating Vi and Vr, HL = 1000 Γ (Vr / Vi), where HL is the Leeb hardness value, Vr is the rebound speed, and Vi is the impact speed.
[0028] Adjustment process:
[0029] When testing larger metal materials, the operator rotates the four bolts 201 so that one end of the bolts 201 is no longer pressed against the surface of the four sliding rods 203. The operator then pulls the handle 4 upwards, which, through the frame 3, causes the eight through-hole blocks 202 to slide on the surface of the sliding rods 203. This allows the frame 3 to move the Leeb hardness tester 5 upwards, enabling the probe of the Leeb hardness tester 5 to adjust the distance between itself and the surface of the support plate 802. After adjustment, the four bolts 201 are tightened again to fix the position of the frame 3. At the same time, the support plate 802 can be pulled, causing the dovetail blocks 801 on both sides to slide out of the base 1, facilitating the removal and cleaning of the support plate 802.
[0030] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
