introduction: 1Cutting edge wear and burr measurement On the spot, it is customary to determine the burr size of the punching piece and determine the grinding time by hand,Excessive error。Of course,The degree of edge wear and edge bluntness can only be detected by detecting the burr height and thickness of the punch、Burr distribution uniformity、Punching size, shape and position accuracy and punching surface quality,Master cutting edge wear、The degree of sharpening of the cutting edge,Determine the timing of sharpening。 Generally, the burr height of the punch can be measured with a micrometer。To improve the measurement accuracy,Each time to test the final continuous punching more than three parts,And at least test every piece3~5dot,averaging。towards

introduction: 1.segregation Uneven distribution of chemical composition and impurities in steel,segregation。Generally will be higher than the average composition,This is called positive segregation,Below average composition,Its called negative segregation。There is macroscopic segregation,Such as regional segregation and micro segregation,Like dendrite segregation,Segregation between crystals。 Segregation in heavy forgings is closely related to ingot segregation,The degree of segregation of the ingot depends on the steel grade、Ingot mould、Smelting quality and pouring conditions are related。Alloying element、Impurity content、Gases in steel all increase the development of segregation。The bigger the ingot,The higher the pouring temperature,The faster the pouring speed,partial

introduction:When designing plastic injection molds,Its design procedures and design points are roughly as follows: 1. Study and analyze product parts drawings,Master the use of plastic partsUse and appearance requirementsAssembly accuracy and determination of allowed gate and flash position.And to understand the plastic variety and its forming process. 2. Select the injection machine specificationsModel number. 3. Production batch according to plastic partsSpecifications of the injection machine and the size of the plastic parts,Determine a mold can produce several plastic parts and position layout scheme. 4. Determine the mold structure scheme.At certainty,Several mold structure forms can be conceived,Make analysis and comparison,Finally decide on an easy system
