How to improve the quality of the fruit of the metal stamping parts

How to improve the quality of the fruit of the metal stamping parts there are many different kinds of automotive stamping parts products, appearance is extremely complex, in stamping parts processing, will often happen some bad phenomenon, in view of the phenomenon of bad, hangzhou xiang jun metal stamping parts made a concrete analysis according to the reality. Intermediate casing holder is car bridge monolithic instrument panel assembly hub bearing fittings, automobile instruments is not random, an important for the safe use of parts. Because of traffic road condition bad, very easy to cause strong vibration and turbulence of cab, resulting in control plate instrument before circuit and open circuit or department function failure. Intermediate casing holder must, therefore, able to withstand the impact and bending fatigue load and torque etc, therefore, requires its must have certain bending strength, shear strength and good toughness. In addition, if the stamping exceed allowable stress during forming, micro cracks or extended to a certain degree, leading to tear or skew, so will not only waste materials, but also will make the mold damage, make the mould life cut short, accelerating mould aging. Found in car cab dashboard bracket assembly production, stamping out the postpartum, of which the casing around stents will often flush tear, askew phenomenon, the obvious defects in the pass of the parts in the corner, side and arc neck close to with wall. Through careful analysis, we think that the main reason is the guide medium pressure during operation of material core mould core gap not disorderly, die and pressure after long-term wear an improper adjustment and mould structure design. Then, can be from two aspects of technology and management, put forward the corresponding control measures, and for the same kinds of metal stamping parts processing, mold design and stamping parts processing and molding to offer help. Metal stamping parts to achieve high-precision stamping industry has always been to achieve the precision stamping this problem, so how to achieve the precision stamping metal stamping? The following by hangzhou xiang jun electronic metal stamping department introduce for everybody! Stamping is sheet metal pieces, that is, through punching, bending, stretching and other means to processing parts, general definition is the thickness of the same parts in the process of stamping parts processing. Corresponding is casting parts, forging parts, machining parts, etc. , such as the outside of the car is iron clad sheet metal parts, some made of stainless steel kitchen utensils and sheet metal parts. Metal stamping parts so far has not yet have a comparatively complete definition, according to a definition of a professional journals abroad can be defined as: sheet metal is aimed at a comprehensive cold working technology for sheet metal, including cutting, punching, cutting, composite, folding, welding, riveting, splicing, molding, etc. The most obvious feature is the same as the thickness of the parts. In general, stamping parts factory is the most important three steps to shear, punching, cutting, folding. Stamping parts and plastic sometimes, this word is derived from the English platemetal, general is a few sheet metal by manually or stamping mould make its produce plastic deformation, forming the desired shape and size, and can be further by welding or a small amount of machining to form more complex parts, such as chimney is commonly used in family, tin furnace, and motor shell are sheet metal parts. Stamping parts processing and sheet metal processing. Using the plate making chimney, iron drum, and the size of the tank of the oil pot, ventilation pipe, elbow, head, day garden place, funnel, etc. Lower production cost is the best way to stamping metal stamping parts production costs accounted for one third of the whole production cost, and in stamping parts processing cost, stamping steel material cost accounts for a large proportion, so in the whole production cost, stamping production to reduce costs, improve material utilization, has become a business focus. A, material thickness and material of choice when selecting a material design of metal stamping parts, should avoid to choose high grade material cause excess product performance at the same time, in meet the requirements of products, stamping parts processing, had better choose existing models used in the mass production material, material thickness, forming material platform, procurement, inventory management, provides the convenience for follow-up. Take the key performance of ordinary manufacture, for instance, the requirement is to pull its ductility, so in accord with the requirement of the quality of the product as far as possible not to choose high grade of material. Material thickness choice, besides should consider the strength of the body after forming, weight, but also pay attention to the material thickness. Because of the special material, it is difficult to supply stamping manufacturers of goods, and prices are not high. A: what is the design principle of metal stamping parts
