Drawing method of manufacturing double metal rod Organization of the diffusion layer and brittle metal compounds asked CuA1, etc. (43400 ℃ the following as the main organization of the diffusion layer to form fine-grained,adidas la trainer, so that welding strength increases; 400 ℃ or more thick due to the formation of intermetallic compounds, resulting in welding strength reduction of thermal management set-degree toe T (℃) Figure 5 sets out the heat treatment specifications for strength of four, the conclusion (1) with double-pull method of manufacturing metal rods, in order to obtain high welding strength, should be used in large-diameter the outer tube. (the switch 28) capacity and lubricant film strength, prevent lubricant film rupture. a large number of trials: the type of lubricant properties of the mold and the workpiece, adding a certain proportion of the extreme pressure additive, or a certain amount of solid lubricant, it has achieved good results. join extreme pressure additives, mainly to increase the lubricating film on metal surface adsorption capacity to produce sulfur, phosphorus, chlorine compounds, generate iron sulfide,adidas climacool hose, ferric chloride and other chemical film, to maintain the lubricating film deformation zone of solid additives to the metal surface is mainly filled with tiny pits,adidas climacool chill, so that the contact points of friction increased, reducing the friction coefficient on the other hand, solid additives high stability, high temperature lubrication can also play a role on the stainless steel draft beer barrel head, the dry plate by the high hardness, intense deformation, resulting in a high-calorie, also called the lubricant must have a strong cooling capacity. Therefore, we have developed with extreme pressure additives, solid additives for water-based lubricant as head of the technology of deep drawing lubricant, its application is better. (3) stainless steel burr blank blanking blanking plate actinides process, inevitably to be glitches, blanking die if not timely maintenance work in the blanking blank edges will result in higher glitch. Kuai has been intense these hair-hardening, so the rough drawing with the burr, the easy pull hurt the mold surface, so that the mold surface to generate more injuries,adidas climacool schuhe, and will produce more chips on the one hand part of the mold surface and the surface interaction scars, scratches the surface of the workpiece; the other hand, the chips generated when drawing with mold and the workpiece to the role of the surface of the workpiece or the workpiece and Ma Hang mold surface defects in the new strain, so the production Sus304 head, (on the next 24) (2) double metal drawing process, internal and external material contact surfaces there is a big speed difference,adidas climacool, which is conducive to welding metal layer (3) The greater the degree of deformation, welding metal rod double greater intensity, so the actual production process,adidas schuhe, can be as high as possible improve the degree of deformation (4) post weld heat treatment can not only eliminate the residual stress, and can improve the welding strength aluminum-copper metal rod double optimum heat treatment specifications for the 40o ℃ × lh. better to increase a deburring process V. Conclusion of stainless steel draft beer barrel head drawing mechanism of defect generation and control analysis, and assessment of actual production,adidas online shop, you can obtain the following conclusions: (1) deep drawing process, the mold and the intense friction between the workpiece, resulting in a lot of friction heat and thermal deformation, resulting in the workpiece and the die of the question, adhesive wear occurred, which is the head surface of the drawing because the nature of defects (2) a reasonable selection of drawing die materials and lubricating materials, parts and tooling to reduce the friction coefficient of Q , so that the mold and the workpiece surface to establish a good extreme pressure lubricant film, is to achieve the draft beer barrel head surface defects drawing an important way to control (3) copper alloy mold with water-based lubricant with the deep drawing of stainless steel draft beer barrel head ,adidas neo, no scratches scratches and other surface defects, thus achieving head drawing surface defect control, significantly improve labor productivity.
