Description

Technical Field

[0002] Hafnium has excellent properties such as high strength, high temperature resistance, and corrosion resistance, and is widely used in the manufacture of aircraft engine parts and aerospace devices;

[0003] When sampling high-purity hafnium metal, mechanical cutting is usually used to cut a small amount of hafnium to detect purity and analyze whether there are impurities. However, this processing method still has the following problems:

[0004] Due to the high structural strength of hafnium, greater external force needs to be applied to break it during the cutting process. This makes it easy for the cutting blade itself to stick to the cut hafnium sample, which can easily interfere with subsequent purity detection tests and reduce the accuracy of hafnium purity detection tests. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a metal sampling device.

[0008] It should be noted that when the cutting blade is cutting metal hafnium, the two sides with the largest area are the main contact surfaces with the metal hafnium, while the two sides with smaller area hardly participate in the contact with the metal hafnium. Therefore, graphite only needs to cover the two sides with the largest area of ​​the cutting blade, and the two sides with the largest area of ​​the cutting blade are obtained by comparing with its other sides.

[0009] Preferably, the graphite conveying assembly includes a return groove opened inside the shell, a movable frame is slidably connected in the return groove, two feeding grooves are opened in the movable frame, two discharge ports are opened in the movable frame, the discharge ports are connected with the inside of the feeding groove, a storage groove for storing graphite is opened on the top of the shell, two discharge channels are opened in the storage groove, each of the discharge channels is fixedly connected with a feeding pipe, the feeding pipe is inserted in the feeding groove, a feeding piece is provided in the storage groove, and the feeding piece selects to feed graphite or close the discharge channel.

[0010] Preferably, the feeding member comprises a double-headed servo motor fixedly connected in the shell, and both driving ends of the double-headed servo motor are fixedly connected with rotating blades, and the rotating blades are arranged inside the feeding channel.

[0011] Preferably, at least one magnet is fixedly connected in the return groove, and a magnetic block is fixedly connected in the movable frame, and the magnetic block and the magnet are magnetically attracted to each other.

[0015] Preferably, there are two clamping members, and the two clamping members are linearly distributed, so that the two clamping members can clamp the metal hafnium together.

[0016] Compared with the prior art, the advantages of the present invention include:

[0017] (1) The present invention provides a metal sampling device, which uses an electrostatic generator to adsorb graphite transported by a graphite transport component to a cutting blade to form a lubricating layer. When cutting metal hafnium, the graphite separates the material of the cutting blade from the metal hafnium, thereby preventing the material of the cutting blade from adhering to the metal hafnium. When the cutting blade leaves the metal hafnium, the graphite on the cut metal hafnium will fall off due to the loss of electrostatic adsorption, making it difficult for the cut surface of the sample to be contaminated by impurities, thereby avoiding interference with subsequent purity detection tests, and further improving the accuracy of the purity detection test of hafnium;

[0018] (2) The present invention provides a metal sampling device, which uses a graphite conveying assembly and a feeding member in combination, and uses a rotating fan blade to deliver a fixed amount of graphite per unit time. The graphite will pass through the feeding channel and the feeding pipe in turn into the feeding slot of the movable frame, and will be sprayed to the side of the cutting blade from the discharge port. At the same time, the movable frame can be pulled toward the outside of the return groove, so that the discharge port moves at a relatively uniform speed, so that the graphite can fully cover the two sides of the cutting blade with a larger area. The electrostatic generator is used to generate electrostatic adsorption on the surface of the cutting blade, so that a graphite lubricating layer is formed on the surface of the cutting blade, thereby preventing the material of the cutting blade itself from contacting with the metal hafnium;

[0019] (3) The metal sampling device provided by the present invention can fix the position of the metal hafnium by setting the clamping member, thereby providing stability for the cutting blade during the process of cutting the metal hafnium. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Further, in order to make the public have a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention. For those skilled in the art, the present invention can be fully understood without the description of these details.

[0038] Example 1

[0039] See also Figure 1 and Figure 2A metal sampling device includes a base frame 1, a cutting tool 2 is arranged on the top of the base frame 1, and the cutting tool 2 includes a shell 21. A cutting blade 24 for cutting metal hafnium is fixedly connected to the bottom of the shell 21. The cutting blade 24 is made of conductive material. The material of the cutting blade 24 can be selected from cemented carbide, diamond and cubic boron nitride. A graphite conveying component for conveying graphite to the surface of the cutting blade 24 is arranged in the cutting tool 2. An electrostatic generator 6 is arranged in the base frame 1. The electrostatic output end of the electrostatic generator 6 is connected to the cutting blade 24 so that the graphite passes through the static electricity. The graphite on the cutting blade 24 is electrically adsorbed on the surface of the cutting blade 24, and the graphite conveying assembly is transported to the graphite on the cutting blade 24 by the electrostatic generator 6 to form a lubricating layer. When cutting metal hafnium, the graphite separates the material of the cutting blade 24 from the metal hafnium, thereby preventing the material of the cutting blade 24 from adhering to the metal hafnium. When the cutting blade 24 leaves the metal hafnium, the graphite on the cut metal hafnium will fall off due to the loss of electrostatic adsorption, making it difficult for the cut surface of the sample to be contaminated by impurities, avoiding interference with subsequent purity detection tests, and further improving the accuracy of the purity detection test of hafnium.

[0040] It should be noted that graphite refers to small granular graphite. When the cutting blade 24 cuts metal hafnium, the two sides with the largest area are the main contact surfaces with the metal hafnium, while the two sides with smaller areas hardly participate in the contact cutting with the metal hafnium. Graphite only needs to cover the two sides with the largest area of ​​the cutting blade 24, and the two sides with the largest area of ​​the cutting blade 24 are obtained by comparing with its other sides.

[0041] See also Figure 5 and Figure 6The graphite conveying assembly includes a return groove provided inside the shell 21, a moving frame 26 is slidably connected inside the return groove, two feeding grooves are provided inside the moving frame 26, two discharge ports 211 are provided inside the moving frame 26, and the discharge ports 211 are communicated with the inside of the feeding groove. A storage groove for storing graphite is provided on the top of the shell 21, two feeding channels are provided in the storage groove, and a feeding pipe 25 is fixedly connected to each feeding channel, and the feeding pipe 25 is plugged into the feeding groove, and a feeding piece is provided in the storage groove, and the feeding piece can select one of feeding graphite or closing the feeding channel, and the graphite conveying assembly and the feeding piece are used in combination. The rotating fan blade 28 is used to deliver a fixed amount of graphite per unit time. The graphite will enter the feeding slot of the movable frame 26 through the feeding channel and the feeding pipe 25 in turn, and will be sprayed to the side of the cutting blade 24 through the discharge port 211. At the same time, the movable frame 26 can be pulled to the outside of the return groove by force, and the discharge port 211 can be manually controlled to move at a relatively uniform speed, so that the graphite can fully cover the two sides of the cutting blade 24 with a larger area. The electrostatic generator 6 is used to generate electrostatic adsorption on the surface of the cutting blade 24, so that a graphite lubricating layer is formed on the surface of the cutting blade 24, thereby preventing the material of the cutting blade 24 itself from contacting with the metal hafnium.

[0042] It can be understood that the shape of the moving frame 26 is adapted to the shape of the circular groove to form a circular plate frame structure, and the two feeding grooves are respectively arranged near the two sides of the cutting blade 24 with the largest area.

[0043] See also Figure 5 , Figure 6 and Figure 7 The feeding member includes a double-headed servo motor 27 fixedly connected to the shell 21. Both driving ends of the double-headed servo motor 27 are fixedly connected with rotating blades 28. The rotating blades 28 are arranged inside the feeding channel. The rotating blades 28 have a plurality of straight plate-shaped blades. When the two straight plate-shaped blades are arranged in a horizontal state with the feeding channel, the feeding channel will be closed, so that the graphite cannot fall into the feeding pipe 25. When the graphite needs to be delivered, the rotating blades 28 are rotated by starting the double-headed servo motor 27. The rotation of the rotating blades 28 will drive the graphite on its straight plate-shaped blades to fall into the feeding channel. The amount of graphite delivered by the straight plate-shaped blades each time is limited, so that the purpose of quantitative delivery per unit time can be achieved.

[0044] See also Figure 8 At least one magnet 29 is fixedly connected in the return groove, and a magnetic block 210 is fixedly connected in the movable frame 26. The magnetic block 210 and the magnet 29 are magnetically attracted to each other. When graphite does not need to be delivered, the position of the movable frame 26 can be fixed by the magnetic attraction between the magnetic block 210 and the magnet 29, thereby preventing the movement of the movable frame 26 from hindering the use of the cutting blade 24.

[0045] See also Figure 1 and Figure 5 The slot of the material storage tank is exposed outside the shell 21, and the slot cover of the material storage tank is provided with a blocking cover 22, which forms a seal with the slot of the material storage tank. By removing the blocking cover 22, an appropriate amount of graphite can be poured into the material storage tank for storage and standby.

[0046] See also Figure 2 and Figure 3 A rotating wall 3 is provided on the top of the base frame 1, and the rotating wall 3 includes a docking clamp 31. Sliding grooves adapted to the docking clamp 31 are provided on both sides of the shell 21. The docking clamp 31 is slidably connected to the sliding groove. One side of the docking clamp 31 is fixedly connected to the cylinder 23. The driving end of the cylinder 23 is fixedly connected to the shell 21. One side of the docking clamp 31 is rotatably connected to a rotating seat 32. A section of the rotating seat 32 is rotatably connected to a short-circuit rod 33. One end of the short-circuit rod 33 is rotatably connected to a connecting seat 34. One end of the connecting seat 34 is rotatably connected to a bottom column 35. The bottom column 35 is fixedly connected to the top of the base frame 1. The bottom column 35, the connecting seat 34, The rotating connections among the short-circuit rod 33, the rotating seat 32, and the docking clamp 31 all adopt damping rotating rods. When not affected by external forces, the connection state among the base column 35, the connecting seat 34, the short-circuit rod 33, the rotating seat 32, and the docking clamp 31 will be fixed. Through the relative rotation among the base column 35, the connecting seat 34, the short-circuit rod 33, the rotating seat 32, and the docking clamp 31, the position of the cutting tool 2 and the angle of cutting the metal hafnium can be adjusted as needed, and by energizing the cylinder 23, its telescopic end drives the housing 21 and the cutting blade 24 to move, so that the cutting blade 24 can cut the metal hafnium without using manpower.

[0047] See also Figure 1 and Figure 4 At least one clamping member 4 for clamping and fixing the metal hafnium is fixedly provided on the top of the base frame 1. The clamping member 4 includes a clamping seat 41 fixedly connected to the top of the base frame 1. A clamping opening is formed through the middle of the clamping seat 41. A positioning plate 42 is slidably connected in the clamping opening. A threaded rod is threadedly connected in the clamping seat 41. One end of the threaded rod is rotatably connected to the positioning plate 42. A handle 43 is fixedly connected to the other end of the threaded rod. After the metal hafnium is inserted into the clamping opening, the threaded rod is controlled to be screwed into the clamping opening by applying force to the handle 43, so that the positioning plate 42 moves and presses the metal hafnium, thereby positioning the metal hafnium.

[0048] There are two clamping members 4, and the two clamping members 4 are linearly distributed so that the two clamping members 4 can clamp the metal hafnium together. By setting the two clamping members 4, the position of the metal hafnium can be fixed, providing stability for the cutting blade 24 during the process of cutting the metal hafnium.

[0049] A material taking box 5 is placed on the top of the base frame 1, and the cut metal hafnium can be supported by the material taking box 5. Then, the metal hafnium can be taken away for inspection by directly holding the material taking box 5 and moving it.

[0050] Understandably,

[0051] In some states, for example, when it is necessary to cut and sample metal hafnium, the metal hafnium is inserted into the clamping port, and the handle 43 is forced to control the threaded rod to be screwed into the clamping port, so that the positioning plate 42 moves to press the metal hafnium, and the position of the metal hafnium is positioned, and then the electrostatic generator 6 is started to transmit static electricity to the cutting blade 24, and then the double-headed servo motor 27 is started to rotate the rotating fan blade 28. The rotation of the rotating fan blade 28 will drive the graphite on its straight plate-shaped blade to fall into the feeding channel. The graphite will pass through the feeding channel and the feeding pipe 25 in turn into the feeding groove of the moving frame 26, and will be sprayed to the side of the cutting blade 24 from the discharge port 211. At the same time, the moving frame 26 can be pulled to the outside of the return groove, so that the discharge port 211 moves at a relatively uniform speed, so that the graphite can fully cover the cutting blade. On the two sides of the sheet 24 with a larger area, the electrostatic generator 6 is used to generate electrostatic adsorption on the surface of the cutting blade 24, so that a graphite lubricating layer is formed on the surface of the cutting blade 24, and then the movable frame 26 is pushed back to its original position, and then the cutting tool 2 is forced to move it to the position and angle required for cutting the metal hafnium. The rotating wall 3 will be pulled by the cutting tool 2 to change its state, and then the cutting tool 2 can be pushed by hand to cut the metal hafnium, or the cylinder 23 can be energized so that its telescopic end pushes the housing 21 and the cutting blade 24 to move, so that the cutting blade 24 cuts a small corner of the metal hafnium. In this process, graphite will cover the incision surface of the metal hafnium. When the sample metal hafnium is cut and dropped, the graphite at the incision will drop due to the loss of electrostatic adsorption ability, that is, a metal hafnium sample with no impurity contamination on the incision surface is obtained.

[0052] It should be noted that the power supply required in this embodiment can be provided by external power supply.

[0053] It should be understood that the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, some simple deductions or substitutions can be made without departing from the concept of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
