Description

Technical Field

[0001] The utility model relates to the technical field of steel quality detection, in particular to a quality detection device for high-strength steel. Background Art

[0002] High-strength steel is a material that, through a special process, possesses greater strength and toughness than ordinary steel. It is widely used in fields such as construction, automotive, aviation, and the military. Due to its high strength and toughness, high-strength steel is less likely to break when subjected to impact. Conventional impact tests, often used to assess a material's toughness and impact resistance, however, may not provide sufficient impact force for high-strength steel, resulting in inaccurate test results.

[0003] Existing testing technologies are often limited by insufficient testing force when dealing with high-strength steel, a material with extremely high strength and toughness. This lack of force means that traditional impact tests cannot cause sufficient impact on high-strength steel to evaluate its true performance, resulting in test results that may not accurately reflect the material's performance in actual applications. In addition, due to insufficient force, the test cannot trigger the expansion of microscopic defects or cracks within the high-strength steel, making it impossible to effectively evaluate the material's impact resistance and fracture toughness. This not only limits the in-depth understanding of material properties, but also brings potential risks to engineering design and product quality control. Utility Model Content

[0004] To this end, the utility model provides a quality detection device for high-strength steel, which is used to overcome the problem in the prior art of poor accuracy in evaluating the impact resistance and fracture toughness of the material due to insufficient detection strength.

[0005] To achieve the above-mentioned purpose, the present invention provides a quality detection device for high-strength steel, comprising:

[0006] The housing is a tube structure with a single-side opening, and is provided with a plurality of grooves inside. A single spring is placed in each groove. A circular hole is provided on the upper end surface of the housing, and a rotating nut is provided above the circular hole.

[0007] The impact assembly includes a magnetic card holder with several extension structures, a screw and an impact hammer head. The magnetic card holder is connected to the springs in the groove through the circular rings on the extension structures. The upper end of the screw extends from the circular hole and engages with the rotating nut. When the rotating nut rotates to drive the screw upward, the spring is in a stretched state and generates elastic stress.

[0008] Furthermore, a magnetic card slot is provided on the bottom surface of the magnetic card seat, and the magnetic card slot is a hollow polygonal prism.

[0009] Furthermore, the top surface of the cavity area of the polygonal prism of the magnetic card slot is provided with a chamfer.

[0010] Furthermore, a polygonal prism protrusion is provided on the top of the impact hammer head, and the polygonal prism protrusion can cooperate and engage with the cavity polygonal prism.

[0011] Furthermore, a protruding ball group is provided on the bottom surface of the rotating nut, and the rotating nut contacts the upper end surface of the shell through the ball group.

[0012] Furthermore, a handle is provided on the side of the rotating nut.

[0013] Furthermore, the side surface of the magnetic card holder is provided with extension structures having the same number as the slots.

[0014] Furthermore, the bottom of the screw slot is configured as a pointed protrusion.

[0015] Furthermore, the length of the screw is greater than the height of the housing.

[0016] Furthermore, the spring is connected with a screw below which engages with the bottom of the slot.

[0017] Compared with the prior art, the beneficial effect of the present invention is that, through the spring embedded in the tubular shell with a single-side opening and the rotating nut above the circular hole, precise control of the impact assembly is achieved. The magnetic card holder is connected to the spring through the circular ring on the extension structure, which ensures that the spring generates stable elastic stress when the screw moves up, thereby achieving precise adjustment of the impact force. This design not only provides structural compactness and ease of operation, but also achieves fine control of the impact force through the interaction between the spring and the screw, thereby improving the accuracy and repeatability of the detection. In addition, through the cooperation of the magnetic card holder and the impact hammer head, the device can be quickly assembled and disassembled, increasing the flexibility of use and the convenience of maintenance. Overall, the design of this device optimizes the high-strength steel detection process, improves detection efficiency and safety, and effectively solves the problem of poor accuracy in evaluating the impact resistance and fracture toughness of the material due to insufficient detection force.

[0018] Furthermore, by adding a magnetic card slot on the bottom surface of the magnetic card holder and designing it as a hollow polygonal prism, and setting a chamfer on the top surface of the cavity area of the magnetic card slot, combined with the polygonal prism protrusion on the top of the impact hammer, the improved design of this high-strength steel quality inspection device significantly enhances its functionality and operational accuracy. The cavity design of the magnetic card slot allows for a secure engagement between the magnetic card holder and the impact hammer, while the geometric properties of the polygonal prism ensure the accuracy and stability of the engagement process. The chamfer optimizes the contact surface between the impact hammer and the magnetic card slot, reducing stress concentration during the impact process and extending the service life of the component.

[0019] Furthermore, the blunt angle design at the bottom of the screw slot enhances structural stability and durability while reducing stress concentration caused by impact. The chamfered top of the inner wall of the magnetic slot optimizes force transmission efficiency and reduces mechanical friction. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figures 1 to 4As shown, this embodiment provides a quality inspection device for high-strength steel, including: a housing 1, a spring 2, a slot 3, a magnetic card holder 41, a screw 42, a striking hammer 43, a rotating nut 5, a handle 6 and a screw 7, wherein:

[0029] The housing 1 has two slots 3 for placing springs 2 therein, and a strip-shaped opening 31 is provided on one side of each slot 3 close to the inner side of the housing 1. The housing 1 has a circular hole 8 on the top.

[0030] The impact assembly includes a magnetic card seat 41 with two extension structures, a screw 42 and an impact hammer head 43. The magnetic card seat 41 is connected to the springs 2 in the two slots 3 through the ring on the extension structure 44 from the strip opening 31. The extension structure 44 is divided into an extension proximal end 441 and an extension distal end 442. The extension distal end 442 is provided with a ring, which passes through the strip opening 31 and is connected to the spring 2. The extension structure 44 can replace multiple ones, such as Figure 3 The magnetic card holder 41 is provided with four extension structures 44. Correspondingly, for the magnetic card holder 41 provided with four extension structures 44, the housing 1 has four corresponding slots 3 for placing the springs 2 and a strip-shaped opening 31. The slot 3 is a hollow annular cylinder, and can also be set as a hollow cylindrical cylinder.

[0031] The lower end of the screw 42 is disposed in the screw slot 45 at the top of the magnetic card holder 41, the upper end of the screw 42 extends from the circular hole 8, and the top of the impact hammer 43 is disposed in the magnetic card slot 46 at the bottom of the magnetic card holder 41;

[0032] The magnetic holder 41 is used to drive the impact hammer 43 to move upward as the screw 42 moves upward, and moves downward when the lower end of the screw 42 is disengaged from the screw slot 45.

[0033] The outer shell 1 is provided with a groove 3 with two springs 2 inside, and is connected to the external environment through a strip-shaped opening 31. The impact assembly consists of a magnetic card holder 41, a screw 42 and an impact hammer 43, wherein the magnetic card holder 41 is connected to the spring 2 in the groove 3 through a circular ring to realize the transmission of force. The lower end of the screw 42 is fixed in the screw slot 45 at the top of the magnetic card holder 41, and the upper end extends out of the circular hole 8. The up and down movement of the screw 42 and the impact hammer 43 is controlled by the rotation of the rotating nut 5. When the screw 42 moves upward, the impact hammer 43 rises accordingly; when the lower end of the screw 42 is disengaged from the screw slot 45, the impact hammer 43 moves downward rapidly under the action of the spring force, thereby realizing the impact test of high-strength steel.

[0034] Through the spring embedded in the tubular shell with one side open and the rotating nut 5 above the circular hole 8, precise control of the impact assembly is achieved. The magnetic card holder 41 is connected to the spring 2 through the circular ring on the extension structure, which ensures that the spring generates stable elastic stress when the screw 42 moves up, thereby achieving precise adjustment of the impact force. This design not only provides structural compactness and ease of operation, but also achieves fine control of the impact force through the interaction between the spring 2 and the screw 42, thereby improving the accuracy and repeatability of the detection. In addition, through the cooperation of the magnetic card holder 41 and the impact hammer head 43, the device can be quickly assembled and disassembled, increasing the flexibility of use and the convenience of maintenance. Overall, the design of this device optimizes the high-strength steel detection process, improves detection efficiency and safety, and effectively solves the problem of poor accuracy in evaluating the impact resistance and fracture toughness of the material due to insufficient detection force.

[0035] Specifically, the upper end of the screw rod 42 is engaged with the rotating nut 5 provided at the circular hole 8 above the housing 1 and can move upward when the rotating nut 5 rotates counterclockwise.

[0036] Specifically, the length of the screw 42 is greater than the height of the housing 1 .

[0038] Through the design of the screw 42 and the rotating nut 5, precise control of the impact force and efficient operation are achieved. The optimization of the length of the screw 42 and the setting of the ball inside the rotating nut 5 not only reduce the friction during rotation and improve the durability and stability of the device, but also make the entire testing process simpler and more efficient through the convenient operation of the handle 6.

[0039] Specifically, a magnetic card slot 46 is provided on the bottom surface of the magnetic card seat 41 , and the magnetic card slot 46 is a hollow polygonal prism.

The hollow design of the magnetic card slot 46 allows for a stable engagement between the magnetic card holder 41 and the impact hammer 43, while the geometric characteristics of the polygonal prism ensure the accuracy and stability of the engagement process. The chamfered setting optimizes the contact surface between the impact hammer 43 and the magnetic card slot 46, reduces stress concentration during the impact process, and extends the service life of the component.

[0043] Specifically, the bottom of the screw slot 45 is configured as a pointed protrusion.

[0044] Specifically, a chamfer is provided on the upper inner wall of the magnetic card slot 46 .

[0045] Specifically, a ball is provided at the end of the extension structure of the magnetic card holder 41 .
