Description

Technical Field

[0001] This utility model relates to the technical field of multi-directional synchronous detection devices, specifically to a multi-directional synchronous detection device for the low-temperature gradient temperature control impact performance of forgings. Background Technology

[0002] In modern industrial production, flange forgings, as critical connecting components, are widely used in numerous fields such as petrochemicals, power energy, and aerospace. Their quality directly affects the safety and reliability of the entire system. In actual service, many flanges need to operate in low-temperature environments, such as cryogenic storage tanks and cryogenic pipeline connections.

[0003] Low temperatures significantly affect the mechanical properties of metallic materials, especially their impact toughness. When a flange is subjected to low-temperature impact, the internal crystal structure of the material is prone to distortion, leading to deformation. This deformation not only alters the flange's appearance but, more importantly, causes deviations in its critical dimensions. Dimensional accuracy is crucial for the tight fit between the flange and other components. If dimensional deviations exceed allowable limits, it can cause sealing failure at the connection points, leading to media leakage. In fields such as chemical engineering, this could result in serious safety accidents and economic losses.

[0004] Currently, after low-temperature impact testing, forgings need to be inspected, which involves many and cumbersome inspection steps. Furthermore, the existing structure cannot be adjusted for flange forgings of different sizes, resulting in limited functionality. Utility Model Content

[0005] Technical problems to be solved In view of the above-mentioned shortcomings of the existing technology, this utility model provides a multi-directional synchronous detection device for the low-temperature gradient temperature control impact performance of forgings, which can effectively solve the problems in the existing technology.

[0006] Technical solution To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a multi-directional synchronous testing device for the low-temperature gradient temperature-controlled impact performance of forgings, including a base plate. Two sets of L-shaped plates and a platform are fixed to one side of the top of the base plate. Limiting blocks are fixed to both sides of the top of the platform. A rotating rod is mounted between the two limiting blocks. A flange is fitted in the middle of the rotating rod. A limiting rod is fixed to the top of the L-shaped plate. An adjustment assembly is fixed to the top of one side of the base plate. The adjustment assembly includes a bottom rail, a bottom slider connected to the bottom rail, and a connecting plate fixed to the top of the bottom slider. A top rail is fixed to the top of the connecting plate. A top slider is fitted to the outside of the top rail. The top of the top slider is fixedly connected to a frame. A measuring rod is fixed inside the frame. The front end of the measuring rod contacts one side wall of the flange.

[0007] Furthermore, the top of the L-shaped plates on both sides are provided with slots, and a threaded screw is fixed in the slot. The bottom end of the threaded screw is fixedly connected to the top end of the limiting rod, and a driven wheel is fixed on both sides of the limiting rod. The bottom end of the driven wheel is in contact with the side wall of the rotating rod.

[0008] Furthermore, the top of the limiting blocks on both sides is provided with a trapezoidal groove structure, and the rotating rod is a threaded rod structure, and the inner side wall of the flange is provided with a threaded groove structure that meshes with the rotating rod.

[0009] Furthermore, the bottom rail and the top rail are perpendicular to each other.

[0010] Furthermore, the frame has the same number of circular slots as the flanges, and the measuring rod is disposed in the circular slots.

[0011] Furthermore, a nut is fitted in the middle of the measuring rod, and a threaded groove structure is provided on the outer side wall of the measuring rod.

[0012] Beneficial effects The technical solution provided by this utility model has the following advantages compared with the known public technology: This invention, through its L-shaped plate and rotating rod structure, allows the user to thread the flange onto the outside of the rotating rod and place it on top of the limiting block. The driven wheels on both sides of the limiting rod contact the outside of the rotating rod, and the adjusting assembly on the other side adjusts the lateral and vertical positions of the measuring rod to facilitate contact with the flange on the base plate. Then, by driving the rotating rod, the deformation result of the flange forging after a low-temperature impact test can be determined by the displacement length of the measuring rod within the frame. This allows for the assessment of the pass rate of the batch of specimens and other experimental data. Therefore, this device allows for simple and rapid testing of multiple sets of flange forgings, fulfilling the requirements of fast and convenient use.

[0013] In this device, the user can adjust the rotating rod structure of different sizes according to the flange forging structure of different sizes by setting the limiting rod and the threaded rod structure. Then, by adjusting the position of the nut on the threaded rod, the contact effect between the driven wheels on both sides and the rotating rod can be adjusted, which facilitates the fixing and clamping of flange forgings of different sizes. The outer adjustment component has a biaxial structure, which facilitates the adjustment of position. The nut structure on the measuring rod can prevent the measuring rod from moving forward and can mark the length at the initial contact, which can help indicate the position of the deformed flange forging.

A flange forging 4 is sleeved in the middle of the rotating rod 17. A limiting rod 12 is fixed to the top of the L-shaped plates 11. An adjustment assembly 2 is fixed to the top of one side of the base plate 1. The adjustment assembly 2 includes a bottom rail 21, a bottom slider 22 connected to the bottom rail 21, and a connecting plate 23 fixed to the top of the bottom slider 22. A top rail 24 is fixed to the top of the connecting plate 23. A top slider 25 is sleeved on the outside of the top rail 24. The top of the top slider 25 is fixedly connected to a frame 26. A measuring rod 3 is fixed inside the frame 26. The front end of the measuring rod 3 contacts one side wall of the flange forging 4. Both sides of the L-shaped plates 11 have slots at their top ends, and adjusting bolts 13 are fixed in the slots. The bottom ends of the adjusting bolts 13 are fixedly connected to the top ends of the limiting rods 12, and driven wheels 14 are fixed on both sides of the limiting rods 12. The bottom ends of the driven wheels 14 are in contact with the side walls of the rotating rods 17. The top ends of the limiting blocks 16 on both sides have trapezoidal groove structures, and the rotating rods 17 are threaded rod structures. The inner side walls of the flange forgings 4 have threaded groove structures that mesh with the rotating rods 17. Through the L-shaped plates 11 and the rotating rods 17 structure, the user can thread the flange forgings 7 onto the outside of the rotating rods 17. The measuring rod 3 is placed on the top of the limiting block 16. It contacts the outer side of the rotating rod 17 through the driven wheels 14 on both sides of the limiting rod 12. The horizontal and vertical positions of the measuring rod 3 are adjusted by the adjustment component 2 on the other side to facilitate contact with the flange forging 7 on the base plate 1. Then, by driving the rotating rod 17, the deformation result of the flange forging 7 after the low temperature impact test can be judged by the displacement length of the measuring rod 3 in the frame 26. In addition, the pass rate of the batch of test pieces and other experimental data can be judged.

In this device, through the setting of the limiting rod 12 and the threaded screw structure, the user can adjust the rotating rod 17 structure of different sizes according to the flange forgings 7 of different sizes. Then, by adjusting the position of the nut 31 on the threaded screw, the contact effect between the driven wheels 14 on both sides and the rotating rod 17 can be adjusted, which facilitates the fixing and clamping of flange forgings 7 of different sizes. The outer adjustment component 2 has a biaxial structure, which facilitates the adjustment of the position.
