Description

Technical Field

[0001] This utility model relates to the technical field of clamping devices, and in particular to a clamping device for metal tensile specimens. Background Technology

[0002] Metallic materials are widely used in various industries. However, when metallic materials are manufactured into finished products, they need to undergo performance testing, including tensile strength, yield strength, elongation after fracture, and modulus of elasticity. During tensile testing, the metallic material sample needs to be clamped. Existing technology publication number CN208818573U proposes a clamping device for tensile testing of metallic materials. It includes a base, on the upper surface of which two parallel ball screws are vertically arranged, and two movable stages are mounted on the ball screws. Each movable stage has a housing on its adjacent sidewall. The housing has a hollow structure with two cavities located on opposite sides. One inner wall of each cavity is rotatably connected to a transversely arranged threaded rod via a rotating component. The end of the threaded rod away from the rotating component penetrates the sidewall of the housing. A matching nut is fitted onto the sidewall of the threaded rod. A first connecting rod is vertically arranged on the sidewall of the nut away from the movable stage. An opening slot is provided on the sidewall of the housing near the first connecting rod, and the first connecting rod passes through the opening slot. However, the clamping stability is poor, and the clamping force on the metal sample is not strong enough, which can easily cause the metal sample to fall off. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a metal tensile specimen clamping device that increases the contact area between the specimen and the metal specimen, increases the friction, ensures the clamping quality, and prevents the specimen from falling off.

[0004] This utility model discloses a metal tensile specimen clamping device, comprising a clamping base, a clamping component, a pushing component, a fixing component, and an mounting component. The mounting component is located on the outer wall of the clamping base, and a clamping opening is provided in the middle of the clamping base. The clamping component is installed in the clamping opening, and the pushing component is installed at the bottom of the clamping base through the fixing component, with the pushing component connected to the bottom of the clamping component. The clamping base is fixed in the use position by the mounting component. When the metal specimen is placed in the clamping opening, the pushing component drives the clamping component to move within the clamping opening, firmly clamping the metal specimen to prevent it from falling off, ensuring stability during the tensile test, and improving the test accuracy.

[0005] Preferably, the clamping component includes multiple clamping blocks, multiple guide rods, and multiple guide sliders. Multiple guide grooves are formed on the inner wall of the clamping opening. Multiple guide rods are respectively installed in the guide grooves, and the guide sliders are slidably installed in the guide grooves and also slidably installed on the outer surface of the guide sliders. The clamping opening is trapezoidal, and the outer walls of the clamping blocks are inclined. The multiple clamping blocks are slidably located within the clamping opening, and the outer walls of the clamping blocks are connected to the guide sliders. After the metal sample is placed into the clamping opening, the multiple clamping blocks move upwards respectively, cooperating with the clamping opening to clamp the metal sample in the middle. The multiple clamping blocks can move independently, making them suitable for metal samples of different shapes. The movement of the clamping blocks causes the guide sliders to slide on the outer walls of the guide rods, guiding and limiting them, improving structural strength, and ensuring stability.

[0006] Preferably, the pushing component includes multiple hydraulic cylinders, multiple push plates, multiple sets of fixed plates, multiple support slide rods, and multiple sliding blocks. The multiple hydraulic cylinders are located below the clamping seat. Push plates are installed on the telescopic ends of the hydraulic cylinders. The bottom of the clamping block slides in contact with the top of the push plate. Fixed plates are installed on the left and right sides of the top of the push plate. Support slide rods are installed between the two fixed plates. A pushing groove is opened at the bottom of the clamping block. The sliding block is installed in the middle of the pushing groove and slides on the outer wall of the support slide rod. When the hydraulic cylinders are activated, they push the push plates to move upward. The push plates push the clamping block to move upward. When the clamping block moves, it causes the sliding block to slide on the support slide rod, which guides and limits the clamping block, improves the structural strength, and ensures the connection stability.

[0007] Preferably, the fixing component includes multiple columns and fixing rings. The multiple columns are evenly installed at the bottom of the clamping seat, and the fixing rings are installed at the bottom of the columns. Multiple hydraulic cylinders are respectively installed at the top of the fixing rings. The hydraulic cylinders are fixedly supported by the columns and fixing rings to ensure stability during use.

[0008] Preferably, it also includes multiple connecting seats, multiple guide rods, and a connecting ring. The connecting seats are installed on the top telescopic end of the hydraulic cylinder. The top of the connecting seats is connected to the bottom of the push plate. Guide rods are installed on the outer wall of the connecting seats. The guide rods are slidably mounted on the fixed ring. The bottom of the fixed ring is equipped with a connecting ring. When the hydraulic cylinder drives the push plate to move through the connecting seats, it drives the guide rods to slide on the fixed ring, guiding and limiting them, increasing the connection strength, and ensuring stability.

[0009] Preferably, the mounting component includes a mounting plate, which is mounted on the outer wall of the clamping seat and has multiple fixing holes; the mounting plate facilitates the installation of the clamping seat in the usage position, making it convenient for use and installation.

[0010] Preferably, it also includes multiple clamping plates. The clamping plates are installed on the inner wall of the clamping block, and the inner wall of the clamping plates is provided with fixing grooves and fixing teeth are provided in the fixing grooves. When the clamping block clamps the metal sample, the clamping plates can increase the contact area between the clamping block and the metal sample, increase the friction, ensure the clamping quality, and prevent the sample from falling off.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the clamping seat is fixed in the use position by the mounting component, the metal sample is placed in the clamping opening, and the clamping component is driven to move in the clamping opening by the pushing component, so as to firmly clamp the metal sample, avoid falling off, ensure the stability during the tensile test, and improve the test accuracy.
