Description

Technical Field

[0001] The utility model belongs to the technical field of micro-nano powder preparation, and in particular relates to a wire feeding mechanism for wire electric explosion powder making equipment. Background Art

[0002] Wire electric explosion refers to the process in which a metal wire, under the action of a pulsed large current with certain parameters, undergoes solid heating, melting, liquid heating, and gasification in a very short time, causing an electric explosion and forming plasma, accompanied by the generation of shock waves and light. Finally, under the action of the explosion impact force, it splashes around at high speed and finally cools into micro-nano powder. This method has the advantages of strong versatility, good powder sphericity, controllable particle size, and green and pollution-free.

[0003] The metal wire electric explosion method has great advantages in preparing micro-nano powders. In recent years, this technology has received widespread attention. At present, there are equipment that can prepare micro-nano powders. However, in the large-scale automated continuous production of micro-nano powders, most of the existing electric explosion equipment uses solid contact between electrodes and metal wires, and then loads pulse current between the two electrodes and applies it to the metal wire to prepare micro-nano powders. Electrode ablation problems are prone to occur in continuous electric explosion preparation, affecting the subsequent preparation process. In addition, the wire pressing and feeding are indirect during the wire feeding process, which reduces the preparation efficiency of micro-nano powders.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0049] By starting the motor 302, the mounting shaft 303 installed at the output end is driven to rotate, so that it drives the mounting disk 304 installed at one end to rotate, and then it can drive the wire pressing assembly 4 installed on the outer surface to perform circular motion. At the same time, as the mounting disk 304 rotates, it can cooperate with the connecting rod 305 installed on one side to drive the limiting ring 306 to perform circular motion, so that it can better support the wire pressing assembly 4.

[0051] A pressure rod 405 is fixedly installed inside the fixed cylinder 403 , and a wire guide rod 406 is fixedly installed on one side of the rotating seat 401 .

[0052] When the mounting plate 304 rotates along with the mounting shaft 303, it can drive the rotating seat 401 installed on one side thereof to rotate, so that the rotating seat 401 drives the connecting frame 402 arranged for internal rotation to rotate in a circle, thereby cooperating with the fixed cylinder 403 installed in the inside to drive the pressure rod 405 to rotate in a circle, and the rotating seat 401 can drive the guide wire rod 406 installed on one side thereof to rotate, so that the guide wire rod 406 and the pressure rod 405 can rotate synchronously, and the setting of the fixing bolt 404 can fix one end of the pressure rod 405, so as to facilitate the installation and disassembly of the pressure rod 405.

[0053] In one embodiment, for the above-mentioned wire pressing assembly 4, the wire pressing assembly 4 also includes a guide plate 407, a guide groove 408 is opened inside the guide plate 407, a guide ball 409 is slidably installed inside the guide groove 408, a guide rod 410 is slidably connected inside the guide ball 409, and one end of the guide rod 410 is fixedly installed inside the fixed tube 403.

[0059] Through the above technical scheme, 1. the wire pressing assembly 4 installed at the output end is driven to rotate by starting the driving assembly 3, so that it can be turned over during the rotation process, so that the electric explosion wire can enter the inner side of the wire pressing assembly 4, and as the wire pressing assembly 4 continues to rotate, it can press the electric explosion wire entering the inner side, and then it is convenient to continuously pull the electric explosion wire out from the outer surface of the wire feeding assembly 2, so that it cooperates with the electric explosion assembly 5 to continuously perform electric explosion processing on the electric explosion wire, thereby improving the preparation efficiency of micro-nano powders;

[0060] 2. The guide rod 410 is driven to rotate in a circle by the fixed cylinder 403. Since the outer surface of the guide rod 410 is slidably arranged inside the guide ball 409, and the outer surface of the guide ball 409 is slidably arranged inside the guide groove 408, the guide rod 410 can be driven to move along the direction of the guide groove 408. Since the guide groove 408 is arranged in an arc shape, when the guide ball 409 moves to the arc position of the guide groove 408, it can drive the guide rod 410 to flip, so that it can cooperate with the fixed cylinder 403 to drive the connecting frame 402 to rotate inside the rotating seat 401, and at the same time, the fixed cylinder 403 drives the internally installed pressure rod 405 to flip, so that when the electric explosive wire is wound around the outer surface of the wire guide rod 406, it is wound around the lower side of the pressure rod 405, so that after the guide ball 409 moves out of the arc position of the guide groove 408, it can cooperate with the guide rod 410 and the fixed cylinder 403 to drive the pressure rod 405 to press the electric explosive wire.
