Description

Technical Field

[0001] The utility model relates to the technical field of powder metallurgy, in particular to a metal powder rod forming production line. Background Art

[0002] A large amount of metal cutting chips are produced during the operation of a machining plant. Generally, the machining plants package and sell the cutting chips to return part of the funds to reduce the processing cost, but this will give up part of the profit to the metal smelting plant, especially the higher-priced metals such as brass, copper and aluminum. In order to minimize the loss, some manufacturers purchase simple metallurgical equipment to melt the metal powder themselves, but the simple metallurgical equipment is not only difficult to operate, but the metal blocks obtained by melting are of extremely poor quality and are not easy to sell.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] See also Figure 1 to Figure 2The utility model provides a technical solution: a metal powder rod production line, including a cake pressing device 1, an induction melting device 2, a drawing device 3, a cutting device 4 and a drying bed 5. An automatic control center 6 and a closed cooling device 7 are installed on the outside of the drying bed 5. A smoke extraction device is installed on the induction melting device 2. The smoke extraction device is used to collect harmful gases generated by smelting to avoid environmental pollution. A crystallizer and a drawing guide rod are arranged on the side of the induction melting device 2 close to the drawing device 3. After the cake is melted, the metal liquid solidifies through the outlet of the crystallizer and is connected to the drawing guide rod. The drawing guide rod generates a pulling force through the drawing and pulling to evenly pull the solidified metal out at a certain rhythm to form a metal rod. The metal rod produced by drawing is cut by the cutting device 4 according to the length set by the automatic control center 6. The cut metal rod is automatically turned over to the drying bed 5 for cooling. The height of the upper surface of the drying bed 5 is slightly lower than that of the drawing guide rod. The height of the discharge port of the dial device 3 can directly receive the rods cut by the cutting device 4. The drying bed 5 is made of high-strength metal material and the shelf has a good heat dissipation effect. The closed cooling device 7 is used to cool the cake pressing device 1 and the induction melting device 2. All equipment in the processing process is automatically controlled by the automatic control center 6, and the workers only need to assist in loading and unloading. The cake pressing device 1 is composed of a hopper 101, a screw rotating conveying pipeline 102, an extrusion chamber 103, a hydraulic station 104, a lower end pushing device 105 and a discharge channel 106. The hopper 101 is used to temporarily store the metal powder to be extruded. The metal powder is transported to the extrusion chamber 103 through the screw rotating conveying pipeline 102. When the hydraulic station 104 is working, it squeezes the metal powder in the extrusion chamber 103 into a cake shape. The lower end pushing device 105 cooperates with the discharge channel 106 to push the extruded metal cake out of the extrusion chamber 103 for easy grasping.

[0020] When in use, the automatic control center 6 first sets the working pressure of the hydraulic station 104 and the operation of each actuator according to the type of metal powder and the purity of the powder. At the same time, the automatic control center 6 sets the heating temperature of the induction smelting equipment 2 and the operation of each actuator. The machining workshop collects various metal fragments and puts them into the hopper 101. The automatic control center 6 is further turned on to control the operation of the production line. The specific process is that the equipment automatically delivers the material to the extrusion chamber 103 through the screw rotating conveying pipeline. After reaching the set amount, the conveying pipe mouth is closed, and the upper hydraulic station 104 applies pressure downward. The raw material is squeezed into a fixed shape through high-strength pressure. The cake-shaped blocks are of a size suitable for smelting, and more than 98% of the lubricating oil added in the machining process of the raw materials are removed. The extruded cake blocks are automatically pushed out to the discharge channel 106 by the lower end pushing device 105, and the extruded cake blocks are put into the induction melting equipment 2 for induction heating and melting. The smoke generated during the heating process is collected by the exhaust equipment to avoid polluting the environment. After the cake blocks are melted, they are solidified through the outlet of the crystallizer and connected with the drawing device 3. The drawing device 3 generates a pulling force through pulling and pulling, and pulls them out evenly at a certain rhythm. Finally, the cutting device 4 cuts them according to the set length, and the cut rods are automatically turned over to the drying bed 5 for cooling.

[0021] In summary, the metal powder rod production line uses the cake pressing equipment 1 to first extrude the metal fragments into blocks to increase their density and then put them into the induction melting equipment 2. It is not only highly efficient but also can reduce dust pollution. In addition, the extrusion molding and smelting processes are all controlled by the automated control center 6, thereby achieving the effect of easily smelting and recycling the metal fragments to reduce production costs. The solidified metal is squeezed by the pulling device 3 to form a rod with a regular shape, and then automatically cut into the required length by the cutting equipment 4 and automatically dropped onto the drying bed 5, thereby easily obtaining rods with good appearance.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
