Description

Technical Field

[0001] The invention relates to an environmental temperature adjustment component for testing the phase change temperature of micro nickel-titanium. Background Art

[0002] Nickel-titanium alloy has shape memory and superelastic properties and is widely used in various fields such as medicine, construction, aerospace, and military. The shape memory and superelastic properties of nickel-titanium alloy are derived from its internal phase change, so the phase change temperature becomes an important parameter for considering the functional performance of shape memory alloy.

[0003] In recent years, tiny nickel-titanium products such as artificial muscles in the medical industry have been continuously developing towards finer and smaller dimensions, and the measurement accuracy requirements have also gradually increased, especially for stable ambient temperature changes. The existing detection ambient temperature change range is small and the temperature is not easy to control. The existing technology urgently needs an ambient temperature adjustment component with a large ambient temperature span and stable control for micro-nickel-titanium phase change temperature testing. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects in the prior art and provide an environmental temperature adjustment component with a large environmental temperature span and stable control for fine nickel-titanium phase change temperature testing.

[0005] The technical solution of the present invention is to provide an environmental temperature adjustment component for fine nickel-titanium phase change temperature testing, comprising a container and a stirring rotor placed in the container, wherein a driving mechanism for driving the stirring rotor to rotate is arranged at the lower part of the container;

[0006] A temperature adjustment component is arranged inside or outside the container, and the temperature adjustment component is in contact with the environmental medium in the container or in contact with the outer surface of the container;

[0007] A load-carrying flow-blocking platform is also arranged in the container.

[0008] This design, by placing the environmental medium in the container, can increase the temperature variation range and expand the temperature variation span of the detection. The flow of the environmental medium can be achieved through the stirring rotor, which can improve the heat exchange efficiency. The temperature in the environmental medium is stable and uniform, thereby improving the detection accuracy. The load-carrying flow-blocking platform can conveniently place the object to be detected. At the same time, it has a certain smoothing effect on the flowing environmental medium, thereby avoiding the influence of environmental medium fluctuations on the detection.

[0009] Preferably, the stirring rotor is a magnetic stirring rotor, and the driving mechanism is a magnetic stirrer. Such a design is more convenient to drive.

[0010] Preferably, the temperature adjustment component is an electric heating pad, and the electric heating pad is arranged at the bottom of the container. Such a design facilitates heating.

[0011] Preferably, the load-carrying flow-blocking platform is a composite structure, including a metal layer at the bottom and a load-carrying layer at the top, and the metal layer and the load-carrying layer are composited together. Such a design facilitates increasing the weight of the load-carrying flow-blocking platform through the metal layer at the bottom, and at the same time improves the anti-deformation ability of the load-carrying flow-blocking platform under hot and cold temperature changes, while the load-carrying layer is selected with a material and color that is conducive to detection, as a background plate.

[0012] Preferably, the load-carrying flow-blocking platform includes a central bearing area and overflow recesses distributed around the central bearing area, wherein the overflow recess is arranged at the outer edge of the load-carrying flow-blocking platform, and the overflow recess is a gap formed by the outer edge of the load-carrying flow-blocking platform being recessed toward the center. Such a design facilitates heat exchange between the environmental medium at the bottom of the load-carrying flow-blocking platform and the environmental medium at the top of the load-carrying flow-blocking platform; ensures the consistency of the temperature of the entire test environment; at the same time, the central bearing area does not generate fluctuations in the environmental medium, which is conducive to camera shooting.

[0013] Preferably, a raised edge is formed between the adjacent overflow recesses, and the raised edge is provided with one, two or more. With such a design, the heat exchange between the ambient medium at the bottom of the cargo-carrying choke platform and the ambient medium at the top of the cargo-carrying choke platform is more stable and uniform.

[0014] Preferably, the load-carrying flow-blocking platform is provided with flow-repression holes or overflow ridges, and the flow-repression holes or overflow ridges are provided at the edge of the central load-carrying area or at the raised edge. Such a design further limits the fluctuation of the environmental medium on the surface of the load-carrying flow-blocking platform and improves the stability of the surface of the environmental medium.

[0015] Preferably, the flow suppression holes are in the shape of long strips, arranged on the raised edge and arranged in pairs. Such a design is an optimization of the solution.

[0016] Preferably, a connection hole is provided on the raised edge, a support column is inserted into the connection hole, a fixing nut is threadedly connected to the support column, and the fixing nuts are arranged in pairs. With this design, the load-carrying flow-blocking platform is erected in the container through the support column, and the stirring rotor is arranged below the load-carrying flow-blocking platform.

[0017] The advantages and beneficial effects of the present invention are as follows: such a design, by placing an environmental medium in the container, can increase the temperature variation range and expand the temperature variation span of detection, realize the flow of the environmental medium by the stirring rotor, improve the heat exchange efficiency, stabilize and unify the temperature in the environmental medium, and improve the detection accuracy; the load-carrying flow-blocking platform can conveniently place the object to be detected, and at the same time, play a certain smoothing role on the flowing environmental medium, avoiding the influence of the environmental medium fluctuation on the detection.

DETAILED DESCRIPTION

[0023] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0024] like Figures 1 to 4 As shown, an environmental temperature adjustment component for fine nickel-titanium phase change temperature testing includes a container 1 and a stirring rotor placed in the container 1, and a driving mechanism for driving the stirring rotor to rotate is provided at the lower part of the container 1;

[0025] A temperature adjustment component is provided inside or outside the container 1, and the temperature adjustment component is in contact with the ambient medium 15 inside the container 1 or in contact with the outer surface of the container 1; the temperature adjustment component can be a heating component or a cooling component. The cooling component can be a cooling pipe, in which a cooling medium flows, and the cooling pipe is provided inside or outside the container 1.

[0026] The container 1 is also provided with a load-carrying flow-blocking platform 2 .

[0027] The environmental medium 15 can be a safe, environmentally friendly, non-toxic and clear liquid medium such as water, alcohol, and edible oil.

[0028] The stirring rotor is a magnetic stirring rotor 3 , and the driving mechanism is a magnetic stirrer 4 .

[0029] The temperature adjustment component is an electric heating pad 5 , and the electric heating pad 5 is arranged at the bottom of the container 1 .

[0030] The carrier flow blocking platform 2 is a composite structure, including a metal layer 6 at the bottom and a carrier layer 7 at the top, wherein the metal layer 6 and the carrier layer 7 are composited together. The carrier layer 7 is preferably a white plastic plate or a black plastic plate, which is conducive to imaging.

[0031] The cargo blocking platform 2 includes a central bearing area 8 and overflow recesses 9 distributed around the central bearing area 8. The overflow recesses 9 are arranged at the outer edge of the cargo blocking platform 2. The overflow recesses 9 are gaps formed by the outer edge of the cargo blocking platform 2 being recessed toward the center.

[0032] A raised edge 10 is formed between the adjacent overflow recesses 9 , and the raised edge 10 is provided with one, two or more.

[0033] The object-carrying flow-blocking platform 2 is provided with a flow-suppressing hole 11 or an overflow ridge, and the flow-suppressing hole 11 or the overflow ridge is arranged at the edge of the central carrying area 8 or on the raised edge 10 .

[0034] The flow suppression holes 11 are in the shape of long strips, and are arranged on the raised edge 10 and in pairs.

[0035] The raised edge 10 is provided with a connection hole 12 , a support column 13 is passed through the connection hole 12 , and a fixing nut 14 is threadedly connected to the support column 13 . The fixing nuts 14 are provided in pairs.

[0036] When in use, the support column 13 is fixed to the connecting hole 12 by the fixing nut 14, and the height of the bottom of the support column 13 is adjusted, the load-carrying flow-blocking platform 2 is placed in the container 1, and the nickel-titanium product is fixed in the central load-bearing area 8; the support column 13 is set at the position of the raised edge 10, which can minimize the influence of the support column 13 on the flow of the environmental medium 15.

[0037] An environmental medium 15 is poured into the container 1. The environmental medium 15 must cover the nickel-titanium product. The environmental medium 15 is heated by the electric heating pad 5. The magnetic stirrer 4 drives the magnetic stirring rotor 3 to rotate, so that the environmental medium 15 in the container 1 is stably heated; the magnetic stirring rotor 3 is set at the lower center of the carrier flow blocking platform 2.

[0038] The shape of nickel-titanium products changes accordingly with temperature changes. The shape changes of nickel-titanium products are captured and recorded by cameras for detection and analysis.

[0039] Due to the rotation of the magnetic stirring rotor 3, the environmental medium 15 at the bottom of the carrier flow blocking platform 2 rotates accordingly, forming a vortex. Since the image captured by the camera is the image of the nickel-titanium product in the environmental medium 15, the upper surface of the environmental medium 15 is required to be as calm as possible to avoid the impact of the fluctuation of the environmental medium 15 on the shooting; therefore, the carrier flow blocking platform 2 is set to isolate the medium vortex at the bottom of the carrier flow blocking platform 2, and the upper surface of the carrier flow blocking platform 2 is kept as calm as possible;

[0040] At the same time, in order to ensure that the environmental medium 15 on the upper and lower surfaces of the load flow blocking platform 2 can exchange heat, a gap is formed by the outer edge of the load flow blocking platform 2 being sunken toward the center, that is, the overflow recess 9. The environmental medium 15 on the load flow blocking platform 2 can exchange heat at the overflow recess 9 to ensure the stability and consistency of the temperature change of the environmental medium 15 in the container 1.

[0041] Heat conduction mainly includes the following forms: first, the heat at the bottom of the container 1 is quickly transferred to the environmental medium 15 at the bottom of the carrier flow-blocking platform 2 through the magnetic stirring rotor 3, and such heat exchange is accompanied by a relatively large medium flow; second, the environmental medium 15 at the bottom of the carrier flow-blocking platform 2 exchanges heat with the environmental medium 15 at the outer edge of the central load-bearing area 8 through the overflow recess 9, and such heat exchange is accompanied by a relatively small medium flow; third, the environmental medium 15 at the outer edge of the central load-bearing area 8 mainly exchanges heat with the environmental medium 15 in the central load-bearing area 8 through molecular thermal motion. In this process, the fluctuation of the environmental medium 15 at the overflow recess 9 is further suppressed by the flow suppression hole 11 or the overflow ridge. Therefore, at the position above the central load-bearing area 8, that is, the position where the nickel-titanium product is placed, the environmental medium 15 basically remains free of fluctuations, thereby ensuring the imaging of the camera.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the invention.
