Description

Technical Field

[0001] This application relates to the field of metal smelting technology, and in particular to an aluminum block sampling tool and a pneumatic pick. Background Technology

[0002] High-purity aluminum has excellent electrical conductivity, plasticity, light reflectivity, ductility, corrosion resistance, and extremely low magnetic permeability, making it widely used in electronics, energy, transportation, medical, computer, aerospace, astronomy, and chemical industries.

[0003] In the production process of high-purity aluminum, to further improve the production efficiency of the segregation purification process, the development of larger diameter purified aluminum ingots is an important trend, namely, using large-diameter crucibles for the segregation purification of molten aluminum. Based on this, as the diameter of the segregated purified aluminum ingots increases, the problem of radial segregation also becomes more prominent. To improve the purification quality of the aluminum ingots after segregation purification, it is usually necessary to transport the produced aluminum ingots between various machine tools to perform a series of cutting operations and obtain test samples.

[0004] This method of obtaining test samples is cumbersome, and the handling of large-diameter aluminum ingots is labor-intensive, time-consuming, and inefficient. Utility Model Content

[0005] Therefore, it is necessary to provide an aluminum block sampling tool and a pneumatic hammer to address the problems of difficulty and low efficiency in obtaining test samples.

[0006] This application provides an aluminum block sampling tool, which includes a connecting rod and a cutting head. The connecting rod is used to connect to the body of a pneumatic pick. The cutting head is connected to one end of the connecting rod and includes a back blade and a front blade, which are disposed opposite to each other. The orthographic projection of the front blade onto the back blade falls in the back blade. The end of the cutting head away from the connecting rod is provided with a cutting edge, which connects the back blade and the front blade, and there is an included angle of 30° to 60° between the cutting edge and the back blade.

[0007] In some embodiments, the angle between the blade and the back of the blade is 45°.

[0008] In some embodiments, the point where the blade meets the back of the blade is the tip of the blade, and the tip of the blade is curved.

[0009] In some embodiments, the maximum length of the cutting line of the blade is 30mm to 50mm.

[0010] In some embodiments, the maximum length of the cutting line of the blade is 40 mm.

[0011] In some embodiments, the length of the blade is 18mm to 26mm.

[0012] In some embodiments, the aluminum block sampling tool further includes an angle bar connected to one end of the tool head near the connecting rod, and the angle bar has an angle of 40° to 50° with the length direction of the tool head.

[0013] In some embodiments, the angle bar is detachably connected to the cutter head.

[0014] In some embodiments, a slider is provided at the end of the angle rod away from the cutter head, and the slider is used to slide on the support plane.

[0015] This application also provides a pneumatic pick, which includes a pick body and an aluminum block sampling tool as provided in any of the foregoing embodiments, with the pick body connected to a connecting rod.

[0016] The aluminum block sampling tool and pneumatic hammer provided in the embodiments of this application have at least the following beneficial effects:

[0017] By configuring the cutter head, which includes a cutting edge, a cutting face, and a cutting back, and connecting the cutting edge to the cutting back and the cutting face, with an angle of 30° to 60° between the cutting edge and the cutting back, the cutting edge can directly impact the surface of the aluminum ingot, whether chiseling vertically or at an angle. This facilitates on-site cutting of aluminum ingots without the need for handling them, saving time and effort. Furthermore, the connecting rod connects to the pneumatic pick body, allowing the pneumatic pick body to control the cutting head, further improving the cutting effect of the aluminum block sampling tool on the aluminum ingot and increasing the efficiency of sample acquisition.

[0029] Please refer to the following: Figure 1 and Figure 2 This application provides an aluminum block sampling tool 100, which includes a connecting rod 10 and a cutting head 20. The connecting rod 10 is used to connect to the pneumatic pick body 200. The cutting head 20 is connected to one end of the connecting rod 10 and includes a blade back 21 and a blade face 22 arranged opposite to each other. The orthographic projection of the blade face 22 onto the blade back 21 falls in the blade back 21. The end of the cutting head 20 away from the connecting rod 10 is provided with a cutting edge 23. The cutting edge 23 connects the blade back 21 and the blade face 22, and there is an included angle of 30° to 60° between the cutting edge 23 and the blade back 21.

[0030] The aluminum block sampling cutter 100 is a tool used for rapid cutting of aluminum ingots. It addresses the problem of cumbersome, time-consuming, and labor-intensive steps in slitting and sampling aluminum ingots as their size increases, allowing operators to quickly slit aluminum ingots on-site without handling them. In these embodiments of the application, the structure of the aluminum block sampling cutter 100 is designed to facilitate cutting and sampling aluminum ingots, thereby improving sampling efficiency by increasing the sampling rate.

[0031] The aluminum block sampling cutter 100 includes a connecting rod 10 and a cutter head 20. The connecting rod 10 is used to connect with the pneumatic pick body 200 so that the impact force of the pneumatic pick body 200 can drive the aluminum block sampling cutter 100 to cut the aluminum ingot, thereby reducing the force required by the operator and improving the operator's user experience.

[0032] In these embodiments of this application, the connection between the cutter head 20 and the connecting rod 10 can be fixed by welding or even integral molding in some embodiments to improve the structural consistency and strength between the cutter head 20 and the connecting rod 10, and reduce the risk of breakage or damage to the aluminum block sampling cutter 100 during use. In other embodiments, the cutter head 20 and the connecting rod 10 can also be detachably connected by threaded connection, snap-fit ​​connection or other means to facilitate subsequent disassembly and assembly of the cutter head 20 and the connecting rod 10, effectively improving the maintenance and replacement efficiency of the aluminum block sampling cutter 100.

[0033] In these embodiments of this application, the cutter head 20 and the connecting rod 10 may be made of materials harder than aluminum, such as iron, titanium, or chromium, to improve the cutting efficiency of aluminum ingots. In some embodiments of this application, the cutter head 20 may be made of titanium, and the connecting rod 10 may be made of a lower-cost iron rod to reduce the production cost of the aluminum block sampling tool 100.

[0034] The connecting rod 10 mainly serves a connecting function. In some embodiments of this application, the cross-sectional shape of the connecting rod 10 may be, but is not limited to, circular, rectangular, triangular, etc.

[0035] The cutting head 20 includes a back 21 and a face 22 disposed opposite to each other. The back 21 and the face 22 are two opposing surfaces of the cutting head 20 along the thickness direction, and the distance between them can define the thickness of the cutting head 20.

[0036] The projection of the cutting face 22 onto the back of the cutting edge 21 falls within the back of the cutting edge 21, meaning that the area of ​​the cutting face 22 is smaller than the area of ​​the back of the cutting edge 21. By reducing the area of ​​the cutting face 22, the portion of the cutting head 20 connecting the cutting face 22 and the back of the cutting edge 21 forms the cutting edge. In other words, the plane containing the cutting face 22 is the machining plane of the cutting head 20 during its forming process. By cutting and grinding a portion of the cutting face 22 obliquely during the forming of the cutting head 20, the cutting edge 23 of the cutting head 20 is formed.

[0037] In some embodiments of this application, the blade 20 may be formed by forging, injection molding, or other methods. Alternatively, the general shape of the blade 20 may be formed by injection molding first, and then the strength of the blade 20 may be improved by forging, refining the structural shape of the blade 20 and forming the cutting edge 23.

[0038] The blade 23 is provided at the end of the cutter head 20 away from the connecting rod 10. That is, the blade 23 is located at the end of the cutter head 20 away from the connecting rod 10, which helps to simplify the operation of the operator when using the aluminum block sampling cutter 100 for cutting and further improves the operator's operating experience.

[0039] The blade 23 connects the back of the blade 21 and the blade face 22, and there is an angle of 30° to 60° between the blade 23 and the back of the blade 21. This allows the blade 23 to achieve higher structural strength, enabling the blade head 20 to adapt to both vertical and oblique cutting, and reducing damage to the blade head 20 itself during cutting. For example, in some embodiments, the angle between the blade 23 and the back of the blade 21 can be set to 25°, 40°, 50°, or 55°. A larger angle results in greater structural strength for the blade head 20 when performing vertical cutting tasks. However, when performing horizontal cutting tasks, the greater thickness at the blade 23 leads to greater resistance. Therefore, the angle between the blade 23 and the back of the blade 21 can be selected according to the intended use of the blade head 20.

[0040] In this way, the integrated design of the cutter head 20 makes the aluminum block sampling cutter 100 easier for operators to operate, enabling the cutting of aluminum ingots at different angles without the need for related technologies to repeatedly handle the aluminum ingots and use different machine tools to cut them, thus allowing for faster and more efficient sampling.

[0041] In some embodiments, the angle between the cutting edge 23 and the back of the blade 21 is 45°. In this way, a good balance can be achieved between the two cutting states of the aluminum block sampling tool 100, thereby providing better applicability.

[0042] In some embodiments, the point where the blade 23 intersects with the back of the blade 21 is the edge of the blade head 20, and the edge of the blade is arc-shaped.

[0043] The blade edge is the part of the blade 23 that first comes into contact with the aluminum ingot. Therefore, the blade edge is designed to be curved to accommodate various cutting angles during operation, further improving the operator's operating experience.

[0044] In some embodiments, the maximum cutting length L of the blade is 30mm to 50mm.

[0045] The maximum length L of the cutting line is the length of the blade 23. The size of L determines the degree to which the blade head 20 is adapted to the cutting angle. When the size of L is larger, that is, the longer the blade 23 is, the larger the arc angle of the blade will be.

[0046] In some embodiments, the maximum cutting line length of the blade is 40mm. In some embodiments, the maximum cutting line length L of the blade can also be set to 32mm, 34mm, 36mm, or 38mm. The cutting line length of the blade can be selected according to actual needs. When the cutting line length of the blade is larger, the blade head 20 will inevitably obtain a smoother cutting effect. At the same time, it will lengthen the blade 23, thereby weakening the overall rigidity of the blade head 20 (the blade 23 will be thinner).

[0047] In some embodiments, the length of the blade 20 is 18 mm to 26 mm.

[0048] The length of the cutter head 20 refers to the dimension of the cutter head 20 in the direction of the connecting rod 10. The length of the cutter head 20 needs to be matched with the length of the blade 23 in order to better transmit the force from the end of the connecting rod 10 to the blade 23. A suitable length of the cutter head 20 can further improve the cutting effect of the blade 23 and provide better protection for the blade 23.

[0049] In some embodiments, the length of the blade head 20 can be set to 20mm, 22mm or 24mm to accommodate different blade lengths 23.

[0050] In some embodiments, the aluminum block sampling tool 100 further includes an angle rod 30, which is connected to one end of the tool head 20 near the connecting rod 10, and the angle rod 30 has an angle of 40° to 50° with the length direction of the tool head 20.

[0051] Angle rod 30 is connected to one end of the cutter head 20 near the connecting rod 10. The function of angle rod 30 is to improve the stability of aluminum block sampling cutter 100 when cutting aluminum ingots, so that the angle between the cutter head 20 and the supporting plane (ground) can remain constant, thereby improving the reliability of the cutter head 20 when cutting aluminum ingots.

[0052] The angle bar 30 and the cutter head 20 have an angle of 40° to 50° along their length. When the operator is cutting the aluminum ingot, the end of the angle bar 30 away from the cutter head 20 can be supported on the support plane, and the pneumatic pick body 200 can be pushed horizontally at the same time to keep the cutting angle of the cutter head 20 on the aluminum ingot moderate and constant within a fixed angle.

[0053] In some embodiments, the angle between the angle bar 30 and the length direction of the cutter head 20 may be set to 42°, 44°, 45°, 46° or 48°.

[0054] In some embodiments, the angle rod 30 and the cutter head 20 are detachably connected. Exemplarily, in some embodiments, the angle rod 30 may have a groove at one end near the cutter head 20, while the cutter head 20 may have a buckle matching the groove at the end opposite the cutting edge 23. In this case, the angle rod 30 and the cutter head 20 can be connected through such a groove-buckle structure. Furthermore, if either the angle rod 30 or the cutter head 20 malfunctions, the operator can quickly disassemble the angle rod 30 and the cutter head 20, improving the efficiency of maintenance and replacement of the aluminum block sampling cutter 100. In some embodiments, the angle rod 30 and the cutter head 20 may also be connected by threads.

[0055] In some embodiments, the end of the angle rod 30 opposite to the cutter head 20 is provided with a slider (not shown), which is used to slide on the support plane.

[0056] In these embodiments of this application, the sliding element may be, but is not limited to, a slide rail, a pulley, or a caster wheel, and can be freely selected according to the cutting requirements of the test sample and the conditions of the aluminum ingot processing site.

[0057] In embodiments where the sliding element is a slide rail or pulley, the sliding element can assist the operator in cutting the aluminum ingot along a straight line, which can further improve the cutting efficiency of the aluminum block sampling tool 100.

[0058] This application also provides a pneumatic pick, which includes a pick body 200 and an aluminum block sampling tool 100 as provided in any of the foregoing embodiments. The pick body 200 is connected to a connecting rod 10.

[0059] The connection between the pneumatic pick body 200 and the connecting rod 10 can be a threaded connection, a snap-fit ​​connection, etc., and this application does not limit it.

[0060] In these embodiments of the present application, the pneumatic pick can be a small pneumatic pick, so that the operator can cut the aluminum round bar individually. This replaces the existing cutting saw equipment for cutting aluminum ingots, which can save a lot of labor costs, material costs and time costs, and has better economic benefits.

[0061] The aluminum block sampling tool 100 can be regarded as the chisel of a pneumatic hammer. It is formed by secondary design and processing of the tip of the chisel. In this way, the matching between the chisel and the hammer can be ensured, and the energy of the hammer can be transmitted to the head of the chisel tip through the chisel. Furthermore, the design of the chisel tip can be improved to combine the blade and the back of the blade in the direction of the cutting force.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
