[0002] High-entropy alloys are alloys formed from five or more metals in equal or approximately equal amounts. They have better fracture resistance, tensile strength, corrosion resistance, and oxidation resistance than traditional alloys, and are therefore widely used. Multilayer high-entropy alloys are co-extruded using an extruder. During the co-extrusion process, the extrusion pressure of the co-extrusion die is used to press the multilayer alloy into shape. However, since the co-extrusion die is in an open state laterally, insufficient vertical pressure is prone to occur, affecting the stability of the multilayer high-entropy alloy pressing. Therefore, this application proposes a multilayer co-extrusion control device for layered high-entropy alloys. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 4 This invention discloses a multilayer co-extrusion control device for a layered high-entropy alloy, comprising a co-extrusion control device body 1. The co-extrusion control device body 1 is composed of several metal co-extrusion devices 2, a co-extrusion die 3, a secondary heating component 4, and an auxiliary lamination mechanism 5. The co-extrusion die 3 is fixedly connected to one end of the metal co-extrusion device 2. The secondary heating component 4 is located at the end of the co-extrusion die 3 away from the metal co-extrusion device 2. The auxiliary lamination mechanism 5 is located at the end of the secondary heating component 4 away from the co-extrusion die 3. One end of the co-extrusion die 3 is provided with several extrusion cavities 6 communicating with the metal co-extrusion devices 2. The other end of the co-extrusion die 3 is provided with a co-extrusion lamination cavity 7 communicating with the extrusion cavity 6.

[0023] The metal co-extrusion device 2 and co-extrusion die 3 can co-extrude the layered high-entropy alloy. The secondary heating component 4 and auxiliary lamination mechanism 5 can perform secondary pressing on the extruded high-entropy alloy to improve the connection stability of the layered high-entropy alloy.

[0024] The auxiliary lamination mechanism 5 consists of a support frame 8, a hydraulic rod 9, a U-shaped support frame 10, an upper pressure wheel 11, and a lower pressure wheel 12. The hydraulic rod 9 is connected through the middle of the top of the support frame 8. The U-shaped support frame 10 is located at the top inside the support frame 8 and is fixedly connected to the hydraulic rod 9. The upper pressure wheel 11 is rotatably connected to the bottom inside the U-shaped support frame 10, and the lower pressure wheel 12 is rotatably connected to the bottom inside the support frame 8.

[0025] During lamination, the hydraulic rod 9 drives the U-shaped support frame 10 to press down, and the U-shaped support frame 10 drives the upper pressure roller 11 to press down. Through the cooperation of the upper pressure roller 11 and the lower pressure roller 12, the layered high entropy alloy is assisted in pressing, thereby improving the connection stability of the layered high entropy alloy.

[0026] The thickness of the co-extrusion lamination cavity 7 is the sum of the thicknesses of the multiple extrusion cavities 6, which can prevent uneven thickness of each layer due to deformation during the co-extrusion process;

[0027] The secondary heating component 4 consists of a heat insulation support frame 13 and a high-frequency heating coil 14. The high-frequency heating coil 14 is fixedly installed inside the heat insulation support frame 13, which can realize secondary heating of the high-entropy alloy after extrusion molding and improve the connection strength.

[0028] An auxiliary support frame 15 is provided on the side of the support frame 8 away from the secondary heating component 4. Several auxiliary support wheels 16 are rotatably provided at the bottom of the auxiliary support frame 15, which can provide auxiliary support for the formed high-entropy alloy.

[0029] An adjusting screw 17 is threaded through the bottom of the support frame 8. The adjusting screw 17 is threadedly connected to the support frame 8. An adjusting handwheel 18 is fixedly installed at the bottom of the adjusting screw 17. A U-shaped support frame 19 is rotatably installed at the top of the adjusting screw 17. A lower pressure wheel 12 is rotatably connected to the top of the U-shaped support frame 19. Limiting sliders 20 that are slidably connected to the support frame 8 are fixedly installed on both sides of the U-shaped support frame 19.

[0030] When extruding layered high-entropy alloys of different thicknesses, the height of the lower pressure roller 12 can be adjusted. During adjustment, the adjusting handwheel 18 is rotated, which drives the adjusting screw 17 to rotate. The adjusting screw 17 drives the U-shaped support frame 19 to rise and fall, and the U-shaped support frame 19 drives the lower pressure roller 12 to rise and fall. The limiting slider 20 can limit the U-shaped support frame 19 to prevent it from deflecting and improve its stability.

[0031] In operation, the system is equipped with a metal co-extrusion device and a co-extrusion die, enabling the co-extrusion molding of layered high-entropy alloys. A secondary heating assembly consisting of a heat-insulating support frame and a high-frequency heating coil, along with an auxiliary lamination mechanism comprising a support frame, hydraulic rods, a first U-shaped support frame, an upper pressure roller, and a lower pressure roller, allows for secondary pressing of the extruded layered high-entropy alloy, improving the stability of the alloy's connection. The auxiliary support frame and auxiliary support roller provide auxiliary support for the molded high-entropy alloy. An adjusting screw, adjusting handwheel, a second U-shaped support frame, and a limiting slider support the lower pressure roller and allow for height adjustment, enhancing adaptability.
