[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The tooling for wire cutting alloy cakes of the utility model utilizes the different diameters of alloy cakes and is designed with an open edge to facilitate clamping of alloy cakes of different specifications. The thickness of the alloy cakes is usually constant. After the alloy cakes are placed in the tooling, the lower plane of the alloy cakes is aligned using the plane of the machine tool, the upper end is exposed to a certain height, the left and right and upper and lower gaps are evenly tightened with set screws, and the cutting allowances left on the left and right sides are guaranteed to be consistent, thereby ensuring the stability of the cutting size and the qualified rate of batch production cakes.

[0026] The present invention provides a tool for wire cutting alloy cakes, such as Figure 1 、 Figure 2 and Figure 3 As shown in the structure, the tooling includes a cake support and a set screw 3; in this embodiment, the tooling with three set screws 3 is used as an example for description; the cake support is a plate-shaped structure as a whole;

[0027] The biscuit support includes a C-shaped frame 1 and a clamping portion 2 that are fixedly connected. The C-shaped frame 1 and the clamping portion 2 can be an integrally formed structure. For example, the C-shaped frame 1 and the clamping portion 2 are integrally cut from 45 steel. The entire structure is made of 45 steel, which ensures the strength, rigidity and stability of the biscuit support. Alternatively, the C-shaped frame 1 and the clamping portion 2 can be separately prepared by cutting, casting, stamping or other processes, and then connected to form a whole by welding, bonding or other processes. The thickness of the C-shaped frame 1 is less than the thickness of the alloy biscuit 4.

[0028] The C-shaped frame 1 is used to clamp the alloy cake 4. A circular space for accommodating the alloy cake 4 is formed on the inner side of the C-shaped frame 1, and an opening is provided on the side away from the clamping portion 2. The clamping portion 2 and the opening are respectively located on both sides of the C-shaped frame 1, which facilitates the clamping of the entire tooling and the assembly and disassembly of the alloy cake 4. The C-shaped frame 1 has at least three threaded holes spaced apart along the circumference, and the threaded holes extend radially along the circular space. Figure 1 and Figure 2 In the description, three threaded holes are used as an example. In the actual production process, in order to improve the uniformity and reliability of clamping, three, four, five or more threaded holes can also be set to install multiple set screws 3; the C-shaped frame 1 has three threaded holes, namely the first threaded hole, the second threaded hole and the third threaded hole; the first threaded hole is arranged opposite to the opening, Figure 2 The threaded hole is located in the middle from top to bottom, and the second threaded hole can be located in Figure 2 The threaded hole on the upper middle side, the third threaded hole is located Figure 2 The second threaded hole and the third threaded hole are symmetrically arranged about the first threaded hole, that is, the second threaded hole and the third threaded hole are symmetrically arranged on both sides of the first threaded hole; the second threaded hole and the first threaded hole are spaced 90° apart, such as Figure 2 As shown, the first threaded hole is arranged opposite to the opening of the C-shaped frame 1 and is located Figure 2 On the right side in the horizontal direction, the axis of the second threaded hole intersects with the axis of the first threaded hole at the center of the alloy cake 4 and forms an angle of 90° rotated counterclockwise. The axis of the third threaded hole intersects with the axis of the first threaded hole at the center of the alloy cake 4 and forms an angle of 90° rotated clockwise.

[0029] A set screw 3 is fitted into the inner thread of each threaded hole, and the length of the set screw 3 is greater than the depth of the threaded hole. After the alloy cake 4 is installed in the C-shaped frame 1, the alloy cake 4 can be clamped from all directions by tightening each set screw. When the C-shaped frame 1 has three threaded holes, the alloy cake 4 is positioned by the set screws 3 on three sides to limit the freedom of the alloy cake 4. The alloy cake is in point contact with the inner end of the set screw 3. Since the gap between the inner circle size of the C-shaped frame 1 and the alloy cake 4 is small, the set screw 3 can ensure a certain tightening force, so that the alloy cake 4 is restricted in a fixed position, so that the dimensional accuracy during cutting can be guaranteed.

[0030] The clamping portion 2 is a flat structure and can be a rectangular plate. The thickness of the rectangular plate is greater than that of the C-shaped frame 1. The C-shaped frame 1 at the front end of the biscuit holder is used to fix the alloy biscuit. The clamping portion 2 at the rear end adopts a thickened design to facilitate clamping and disassembly. The overall operation is simple and the controllability is strong.

[0031] When using the above-mentioned tool to cut the alloy cake 4, the clamping portion 2 is fixed to the vise. The alloy cake 4 is placed into the cake holder by the limiting function of the C-shaped frame 1 of the cake holder. The bottom surface of the alloy cake 4 is adjusted and leveled using the machine tool plane. After the alloy cake 4 is exposed to a certain height above the upper surface of the tool, the set screw 3 is tightened to ensure the parallelism of the molybdenum wire and the cutting plane. At the same time, the cutting allowance is adjusted according to the bottom surface. This ensures that the cutting allowance on both sides of the cake is consistent and prevents the alloy cake 4 from being offset due to the shaking of the molybdenum wire.

[0032] Alloy cakes of different diameters can be placed into the cake holder through the C-shaped frame 1, and the size of the alloy cake can be adjusted by the set screw.

[0033] The thickness of the C-shaped frame 1 at the front end of the tooling is smaller than the actual thickness of the alloy cake 4, ensuring that the exposed excess material is cut off during the cutting process; the thickness of the rear end clamping part 2 is increased to ensure the rigidity and strength of the whole, ensuring that the shaking of the molybdenum wire during the cutting process will not affect the cake.

[0034] The above-mentioned tooling utilizes the C-shaped frame 1 of the cake holder to limit the circumference of the high-entropy alloy cake 4, and clamps the alloy cake 4 from multiple angles through the fixing screws 3 threadedly installed on the C-shaped frame 1. The use of this tooling facilitates the disassembly and positioning of the cake, and utilizes the machine tool plane to control the flatness of the bottom surface of the cake. Due to the large thickness of the cake, it is convenient to cut the excess material; therefore, the tooling of the utility model has the characteristics of easy clamping, convenient disassembly, easy operation, fast positioning, good cake size consistency and high pass rate.

[0035] Obviously, those skilled in the art may make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
