Description

Technical Field

[0001] This utility model relates to the field of feeding technology for ferritic steel drop hammer impact testing, and in particular to a feeding device for ferritic steel drop hammer impact testing. Background Technology

[0002] Ferritic steel, a widely used metallic material in industry, requires accurate performance testing to ensure the quality and safety of related products. The drop weight impact test for ferritic steel is a key method for evaluating its toughness and impact resistance under dynamic loads, playing a crucial role in the inspection of metallic materials. With the increasing demands for metallic material performance in modern industry, the importance of the drop weight impact test for ferritic steel is becoming increasingly prominent, leading to a growing demand for drop weight testing machines and related feeding devices.

[0003] The testing standard GB / T6803-2008 provides detailed specifications for all aspects of the drop hammer test method for the non-plastic transformation temperature of ferritic steels, including the scope, principle, terminology and definitions, specimens, testing equipment and instruments, testing requirements, testing procedures, evaluation of test results, and test reports. Among these, six different specimen types with varying dimensions present a significant challenge to the design of the feeding device. Traditional manual feeding methods are not only inefficient and time-consuming but also pose a high risk of injury to operators. Therefore, we propose a feeding device for the drop hammer impact test of ferritic steels to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding device for a ferritic steel drop hammer impact test.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feeding device for a drop hammer impact test of ferritic steel includes a base, a drop hammer tester mounted on the upper end of the base, multiple specimen anvils fixed at equal intervals at the bottom of the drop hammer tester, two support rods mounted on one side of the base, cylinders rotatably connected to the upper end of the support rods, and a bearing plate rotatably connected to the piston rods of the two cylinders, a feeding frame fixed on the bearing plate, four stops mounted at equal intervals on the feeding frame, with two stops forming a group and the two groups of stops being staggered, one end of the feeding frame rotatably connected to the base, and one end of the feeding frame corresponding to the specimen anvils, and an inductive switch mounted on one side of the upper end of the base, with one side of the inductive switch corresponding to the specimen anvils.

[0007] Preferably, a mounting base is fixed to one side of the lower end of the support rod, and one side of the mounting base is detachably mounted on one side of the base.

[0008] Preferably, a fixing member is fixed to the end of the piston rod of the cylinder, and a T-shaped connecting block is rotatably connected to the fixing member. The lower end of the T-shaped connecting block is fixed to one side of the upper end of the bearing plate.

[0009] Preferably, a mounting plate is fixed to the middle of the bearing plate, and a barrier plate is fixed to the upper end of the mounting plate, with the barrier plate located in the middle of the feeding frame.

[0010] Preferably, the two cylinders are controlled by a synchronization control system.

[0011] In this utility model,

[0012] 1. Initial state: The initial state of the feeding rack is when the feeding cylinder is retracted into position, with an initial tilt angle of 68°. This state can completely clear the area directly under the hammer of the equipment, effectively preventing damage to the feeding rack due to operational errors.

[0013] 2. Place the sample: Open the access control and place the sample above the sample rack block, ensuring that the bottom of the sample is in close contact with the feeding rack. The purpose of the block is to position the sample and prevent it from sliding or shifting during the feeding process, ensuring that the sample can be accurately delivered to the test position.

[0014] 3. Feeding process: When the feeding button is clicked, the feeding rack falls down and is flush with the bottom surface of the sample anvil. At this time, one end of the feeding rack continues to descend, so that the sample placed on the feeding rack is slowly placed on the sample anvil as the feeding rack moves. The sample falls smoothly without being subjected to additional impact or vibration, ensuring the accuracy and stability of the sample placement.

[0015] 4. Feedback and Testing: After the sample is placed stably on the sample anvil, the inductive switch will provide a feedback signal indicating that the material has been fed into place. After the control system receives the feedback signal, it can start the test and perform a drop hammer impact test. During the test, the hammer of the drop hammer tester will fall from a certain height to impact the sample in order to test the impact resistance of ferritic steel.

[0016] This utility model has the following advantages:

[0017] 1. Automatic feeding is achieved through a feeding cylinder, combined with feedback signals from an inductive switch, making the entire feeding process more automated and efficient, reducing manual intervention and improving test efficiency;

[0018] 2. The blocks and baffles designed on the feeding rack can accommodate specimens of different lengths specified in the test standards, meet the feeding requirements of various types of specimens, and improve the versatility and applicability of the feeding device.

[0019] 3. Its initial tilt angle is 68° and it completely avoids the area directly under the hammer of the equipment, which can effectively prevent damage to the feeding rack due to operational errors and ensure the safety of the equipment and operators.

[0020] In summary, compared with the traditional manual feeding method, the automatic feeding of this utility model reduces the manual intervention, greatly shortens the feeding time, and improves the overall efficiency of the test. In addition, it can meet the feeding needs of various types of samples, improves the versatility and applicability of the feeding device, and can also effectively avoid damage to the feeding rack due to operational errors, thus ensuring the safety of equipment and operators.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-3 A feeding device for a ferritic steel drop hammer impact test includes a base 7, a drop hammer tester 3 is installed on the upper end of the base 7, and multiple sample anvils 15 are fixed at equal intervals inside the bottom of the drop hammer tester 3. The design of equal intervals helps to standardize the test layout and ensure the consistency of each test.

[0027] Two support rods 2 are installed on one side of the base 7. A cylinder 1 is rotatably connected to the upper end of the support rod 2. The piston rods of the two cylinders 1 are rotatably connected to a bearing plate 10. A feeding rack 11 is fixed on the bearing plate 10. Four stops 12 are installed at equal intervals on the feeding rack 11. Two stops 12 form a group, and the two groups of stops 12 are staggered. The staggered arrangement of the stops 12 can better position and fix the sample. Different specifications and shapes of samples require different positioning methods. The staggered arrangement of the stops 12 can adapt to the placement requirements of various samples and improve the versatility of the device. At the same time, the spacing and height of the stops 12 can be adjusted according to the size of the sample, further enhancing the flexibility of the device.

[0028] One end of the feeding rack 11 is rotatably connected to the base 7, and one end of the feeding rack 11 corresponds to the sample anvil 15. An inductive switch 6 is installed on one side of the upper end of the base 7, and one side of the inductive switch 6 corresponds to the sample anvil 15. A mounting base 4 is fixed on one side of the lower end of the support rod 2. One side of the mounting base 4 is detachably installed on one side of the base 7. The detachable installation method facilitates the assembly and disassembly of the device, and makes it convenient for transportation and storage. On the other hand, when the support rod 2 or the mounting base 4 is damaged, it can be easily replaced, reducing maintenance costs.

[0029] A fixing member 8 is fixed to the end of the piston rod of cylinder 1. A T-shaped connecting block 9 is rotatably connected to the fixing member 8. The lower end of the T-shaped connecting block 9 is fixed to one side of the upper end of the bearing plate 10. The rotatable connection allows the linear motion of cylinder 1 to be converted into the rotational motion of the bearing plate 10, thereby realizing the lifting action of the feeding rack 11. The design of the T-shaped connecting block 9 increases the stability and reliability of the connection, can withstand greater forces, and ensures the smooth progress of the feeding process.

[0030] A mounting plate 14 is fixed in the middle of the bearing plate 10, and a barrier plate 13 is fixed at the upper end of the mounting plate 14. The barrier plate 13 is located in the middle of the feeding rack 11. The function of the barrier plate 13 is to prevent the samples from colliding with each other or slipping during the feeding process.

[0031] The two cylinders 1 are controlled by a synchronous control system. The synchronous control system can ensure that the two cylinders 1 move synchronously, avoiding the feeding rack 11 from tilting or moving unstably due to asynchronous movement, which would affect the accuracy of feeding and the stability of sample placement.

[0032] In this utility model,

[0033] 1. Initial state: The initial state of the feeding rack 11 is that the feeding cylinder is retracted into position, and the initial tilt angle is 68°. This state can completely avoid the area directly under the hammer of the equipment, effectively preventing damage to the feeding rack 11 due to operational errors.

[0034] 2. Place the sample: Open the access control and place the sample above the sample rack stop 12, ensuring that the bottom surface of the sample is in close contact with the feeding rack 11. The purpose of the stop 12 is to position the sample and prevent it from sliding or shifting during the feeding process, so as to ensure that the sample can be accurately delivered to the test position.

[0035] 3. Feeding process: When the feeding is clicked, the feeding rack 11 falls down and is flush with the bottom surface of the sample anvil 15. At this time, one end of the feeding rack 11 continues to descend, so that the sample placed on the feeding rack 11 is slowly placed on the sample anvil 15 with the movement of the feeding rack 11. The sample falls smoothly without being subjected to additional impact or vibration, ensuring the accuracy and stability of the sample placement.

[0036] 4. Feedback and Testing: After the sample is placed stably on the sample anvil 15, the inductive switch 6 will provide a feedback signal indicating that the material has been fed into place. After the control system receives the feedback signal, it can start the test and perform a drop hammer impact. During the test, the hammer of the drop hammer tester 3 will fall from a certain height to impact the sample in order to test the impact resistance of ferritic steel.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
