Description

Novel deoxidized aluminum rod extrusion shearing production process Technical Field The application belongs to the technical field of aluminum rod forming, and particularly relates to a novel extrusion shearing production process of a deoxidized aluminum rod. Background Aluminum is a metal element, the symbol of the element is Al, the atomic number is 13, the simple substance is silvery white light metal, the product is often manufactured into a rod shape, a sheet shape, a foil shape, a powder shape, a strip shape and a thread shape, and the deoxidized aluminum rod plays a vital role in actual production and life. The invention patent 2023109001047 relates to the field of aluminum material processing and recovery, in particular to an automatic processing and recovery system for aluminum scraps pressed cakes, which comprises an aluminum cake reversing device, a deburring device and an aluminum cake receiving device, wherein the aluminum cake reversing device comprises a rotary table capable of intermittently rotating by 90 degrees, four supporting plates are uniformly distributed on the circumference of the outer circular surface of the rotary table, and the pressing efficiency of the aluminum scraps pressed cake device is low and the pressing effect is poor. The Chinese patent 2019104090461 belongs to the technical field of scrap recycling and treatment, and particularly relates to an aluminum scrap briquetting device, which comprises a base frame, a feeding mechanism, a briquetting turnover mechanism and a conveying mechanism, wherein the briquetting turnover mechanism comprises 4 pushing plates for compacting aluminum scraps, and the briquetting device cannot meet the requirement of mass production. When the aluminum scraps raw materials are pressed into aluminum cakes in the prior art, as the raw materials contain part of cutting fluid and impurities, if the cutting fluid and the impurities cannot be discharged in advance, the subsequent pressing difficulty can be improved, and meanwhile, the quality of the aluminum cakes can be reduced. If the cutting fluid and impurities in the raw materials are discharged, the gravity of the raw materials correspondingly changes, and the size of the aluminum cake can not meet the requirement when the subsequent aluminum cake is directly pressed, so that the quality of the aluminum cake is reduced. Meanwhile, when the raw materials are fed in a sliding manner, part of the raw materials can be adhered to the top of the elastic discharging plate, so that the discharging amount is reduced, and if the raw materials are directly stacked inside the inner cylinder for subsequent pressing, the pressing difficulty is improved, and meanwhile, the internal strength of an aluminum cake is also reduced. When the bottom of the raw material is supported and limited only by the supporting plate, the supporting stability is poor, the supporting strength is low, and the aluminum cake is easy to deviate when being used for a long time, so that the strength and the stability of the aluminum cake are reduced. And after the pressing of raw materials is accomplished and becomes the aluminium cake, the surface of aluminium cake produces the burr easily, especially aluminium cake and extrusion week side of stripper plate and backup pad to and drainage position all probably produce a large amount of burrs, if can not clean this burr, not only can reduce aluminium cake quality, increase follow-up stability and the processing accuracy nature of putting, still cause the conveyer scratch simultaneously easily to appear unnecessary potential safety hazard.
