Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of metallic materials, specifically to a toughness testing device for metallic material products. Background Technology
[0002] Metallic materials refer to materials with properties such as luster, ductility, electrical conductivity, and thermal conductivity. Metallic materials generally refer to pure metals or alloys used in industrial applications. The properties of metallic materials are generally divided into two categories: process performance and service performance. Toughness refers to the ability of a material to absorb energy during plastic deformation and fracture. The toughness test of metallic materials involves a load applied to the machine part at a high speed, which is called an impact load. The ability of a metal to resist damage under impact load is called impact toughness.
[0003] In the production process of metal products, it is necessary to conduct toughness testing on the metal materials to ensure their quality and meet toughness requirements.
[0004] A search revealed a utility model patent in China with publication number CN217586631U: a device for testing the toughness of metal materials. A pressing head is positioned above a receiving seat. Second sliding grooves are provided on both sides of the receiving seat and are mounted on a device base. A motor is located on one side of the device base and is connected to the device base by screws. A support seat is positioned above the second sliding groove, and a second slider is positioned below the support seat. One end of the second slider extends into the interior of the second sliding groove. A bidirectional threaded rod is provided inside the second sliding groove and is threadedly connected to the second slider.
[0005] During the stamping inspection process, the stamping head rubs and impacts the surface of the metal product. Frequent use will cause wear on the surface of the stamping head, which will affect the subsequent stamping inspection results and reduce the accuracy of toughness testing. Existing testing devices are not convenient for disassembling and replacing the stamping head, and have poor practicality. Therefore, a toughness testing device for metal products is needed to improve the above problems. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a metal material product toughness testing device that improves the accuracy of test data and has high practicality by enabling the installation and disassembly of the impact head through the cooperation of an installation and replacement mechanism.
[0008] (II) Technical Solution
[0009] To achieve the above objectives, this utility model provides the following technical solution: a toughness testing device for metal material products, including a platform, a U-shaped plate fixedly installed on the platform, an electric cylinder fixedly installed on the U-shaped plate, and a connecting plate fixedly installed on the electric cylinder;
[0010] The connecting plate is equipped with an installation and replacement mechanism, which includes a mounting plate, an impact head fixedly mounted on the mounting plate, two T-blocks symmetrically fixedly mounted on the mounting plate, two T-slots symmetrically opened on the connecting plate, the two T-blocks slidingly connected to the two T-slots respectively, two sliding grooves symmetrically opened on the connecting plate, a movable plate slidably mounted in each of the two sliding grooves, two connecting rods symmetrically fixedly mounted on each of the two movable plates, a locking plate fixedly mounted on each connecting rod, multiple movable grooves corresponding to multiple locking plates on the connecting plate, each locking plate slidingly connected to the corresponding movable groove, multiple slots corresponding to multiple locking plates on the two T-blocks, each locking plate slidingly connected to the corresponding slot, a spring fitted on each connecting rod, each end of the spring being fixedly connected to the movable groove and the locking plate respectively, and two first limiting plates symmetrically fixedly mounted on each of the two movable plates, each first limiting plate being screwed to the connecting plate by a corresponding first bolt.
[0011] Two limiting mechanisms are provided on the U-shaped plate. One of the limiting mechanisms includes a first fixed plate, which is fixedly installed on the U-shaped plate. A second fixed plate is fixedly installed on the U-shaped plate. Two electric push rods are symmetrically fixedly installed on the first fixed plate. The two electric push rods are connected by a pressure plate. Metal material parts are placed on the two second fixed plates. Two dynamic force sensors are symmetrically arranged on the connecting plate.
[0012] The T-block is secured by two stabilizing components.
[0013] Preferably, one of the stabilizing locking components includes a second limiting plate, which is rotatably connected to the connecting plate, and the second limiting plate is screwed and locked to the T-block by a second bolt.

[0018] (III) Beneficial Effects
[0019] Compared with the prior art, this utility model provides a toughness testing device for metal material products, which has the following beneficial effects:
[0020] Squeeze the two movable plates, causing them to move multiple clamping plates, allowing the two T-blocks to slide into the connecting plate. Release the two movable plates, and the spring force of multiple springs will reset the clamping plates. The clamping plates will engage with their corresponding slots, thus limiting the movement of the two T-blocks and achieving the installation of the mounting plate and impact head. Rotating the multiple first bolts will limit the movement of the multiple first limiting plates and the two movable plates, making the impact head more stable. Place the metal part on the two second fixed plates, and activate multiple electric push rods. An electric push rod drives two pressure plates to move, pressing the metal parts together and thus limiting their movement. An electric cylinder then moves an impact head to test the toughness of the metal parts. Two dynamic force sensors record the changes. When the impact head needs to be replaced, the limiting action on the moving plate and T-blocks is released, and the two T-blocks are slid to disengage from the connecting plate. Replacing the impact head improves the accuracy of the test data. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example
[0028] Please see Figure 1 and Figure 2 A toughness testing device for metal materials includes a platform 1, a U-shaped plate 2 fixedly mounted on the platform 1, an electric cylinder 3 fixedly mounted on the U-shaped plate 2, and a connecting plate 4 fixedly mounted on the electric cylinder 3.
[0029] Please see Figure 1-4 The connecting plate 4 is equipped with an installation and replacement mechanism, which includes a mounting plate 5. An impact head 6 is fixedly mounted on the mounting plate 5. Two T-blocks 7 are symmetrically fixedly mounted on the mounting plate 5. Two T-slots are symmetrically formed on the connecting plate 4, and the two T-blocks 7 are slidably connected to the two T-slots respectively. Two sliding grooves are symmetrically formed on the connecting plate 4, and movable plates 8 are slidably mounted in each of the two sliding grooves. Two connecting rods 9 are symmetrically fixedly mounted on each of the two movable plates 8. A locking plate 10 is fixedly mounted on each connecting rod 9. Multiple movable grooves are formed on the connecting plate 4 corresponding to the multiple locking plates 10, and each locking plate 10 is slidably connected to its corresponding movable groove. Multiple slots are formed on the two T-blocks 7 corresponding to the multiple locking plates 10, and each locking plate 10 is slidably connected to its corresponding slot. A spring 1 is fitted on each connecting rod 9. 1. Each spring 11 has its two ends fixedly connected to the moving groove and the clamping plate 10, respectively. Squeezing the two moving plates 8 causes the two moving plates 8 to drive the multiple clamping plates 10 to move, so that the two T-blocks 7 are slidably connected to the connecting plate 4. Releasing the two moving plates 8 causes the multiple clamping plates 10 to reset through the elastic force of the multiple springs 11 themselves. The multiple clamping plates 10 are engaged with the corresponding clamping grooves to limit the two T-blocks 7, thereby realizing the installation of the mounting plate 5 and the impact head 6. Two first limiting plates 12 are symmetrically fixedly installed on each of the two moving plates 8. Each first limiting plate 12 is screwed to the connecting plate 4 by a corresponding first bolt 13. By rotating the multiple first bolts 13, the multiple first limiting plates 12 and the two moving plates 8 are limited, making the impact head 6 more stable.
[0030] Please see Figure 1 and Figure 2The U-shaped plate 2 is equipped with two limiting mechanisms. One of the limiting mechanisms includes a first fixed plate 14, which is fixedly installed on the U-shaped plate 2. A second fixed plate 15 is fixedly installed on the U-shaped plate 2. Two electric push rods 16 are symmetrically fixedly installed on the first fixed plate 14 and connected by a pressure plate 17. Metal material parts 18 are placed on the two second fixed plates 15. Two dynamic force sensors 19 are symmetrically arranged on the connecting plate 4. When the metal material parts 18 are placed on the two second fixed plates 15, multiple electric push rods 16 are activated, which drive the two pressure plates. 17 performs a moving operation, using the cooperation of two pressure plates 17 to press the metal material product 18, thereby performing a pressing and limiting operation on the metal material product 18. By activating the electric cylinder 3, the electric cylinder 3 drives the impact head 6 to move, and the impact head 6 performs a toughness test on the metal material product 18. The change data is recorded by two dynamic force sensors 19. When it is necessary to replace the impact head 6, the limiting operation on the moving plate 8 and T-block 7 is released, and the two T-blocks 7 are slid to disengage from the connecting plate 4. By replacing the impact head 6, the accuracy of the test data is improved.
[0031] Please see Figure 3 The T-block 7 is stabilized and locked by two stabilizing components. One of the stabilizing and locking components includes a second limiting plate 20, which is rotatably connected to the connecting plate 4. The second limiting plate 20 is screwed and locked to the T-block 7 by a second bolt 21. By rotating the second limiting plate 20, one end of the second limiting plate 20 is made to fit against the T-block 7. By rotating the second bolt 21, the second bolt 21 is screwed and locked to the T-block 7, thereby limiting the T-block 7 and making the mounting plate 5 and the impact head 6 more stable.
[0032] Please see Figure 1 and Figure 2 Both pressure plates 17 are equipped with rubber pads 22 at their bottom ends. The use of the two rubber pads 22 makes the pressure of the two pressure plates 17 on the metal material product 18 more stable.
[0033] Please see Figure 2 It should also be noted that a stabilizing plate 23 is fixedly installed on the inner side wall of the bottom end of the U-shaped plate 2, and the electric cylinder 3 is slidably connected to the stabilizing plate 23. The stabilizing plate 23 makes the electric cylinder 3 more stable.
[0034] Please see Figure 1 and Figure 2 Ribs 24 are fixedly installed at the bottom of the two second fixing plates 15. The two ribs 24 are fixedly connected to the inner sidewalls of both ends of the U-shaped plate 2. The two ribs 24 make the two second fixing plates 15 more stable, thereby making the metal material product 18 more stable.
[0035] Please see Figure 2-4 Each of the two movable plates 8 is fixedly equipped with a slide rod 25. The connecting plate 4 has two sliding holes corresponding to the two slide rods 25. Both slide rods 25 are slidably connected to the connecting plate 4. The slide rods 25 make the movable plates 8 more stable when moving.
[0036] In summary, when using this metal material toughness testing equipment, squeezing the two movable plates 8 causes them to move multiple clamping plates 10, allowing the two T-blocks 7 to slide and connect with the connecting plate 4. Releasing the two movable plates 8 allows the clamping plates 10 to reset via the elastic force of the multiple springs 11. The clamping plates 10 engage with their corresponding slots, thus limiting the movement of the two T-blocks 7 and enabling the installation of the mounting plate 5 and the impact head 6. Rotating the multiple first bolts 13 limits the movement of the multiple first limiting plates 12 and the two movable plates 8. Rotating the second limiting plate 20 causes it to engage with one end of the T-block 7. Rotating the second bolt 21 locks the second bolt to the T-block 7, thus limiting the movement of the T-block 7. To make the mounting plate 5 and impact head 6 more stable, the metal material part 18 is placed on the two second fixed plates 15. Multiple electric push rods 16 are activated, which drive the two pressure plates 17 to move. The two pressure plates 17 work together to press the metal material part 18, thereby pressing and limiting the metal material part 18. The electric cylinder 3 is activated, which drives the impact head 6 to move. The impact head 6 performs toughness testing on the metal material part 18. The change data is recorded by two dynamic force sensors 19. When the impact head 6 needs to be replaced, the limiting operation on the moving plate 8 and T-block 7 is released. The two T-blocks 7 are slid to disengage from the connecting plate 4. The accuracy of the test data is improved by replacing the impact head 6.
