        冲 pressure mold is in pressure production process in process equipment, for improve/increase product quality, long product lifespan, improve/increase production efficiency has property function. however, due to pressure mold in production process in due to abrasion loss 而失 工 as dimensions, very difficult meet/satisfy production demand. therefore, improve/increase pressure mold resistant use degree very key/critical.

         improve/increase pressure mold resistant use degree methods generally has below/following several:

        改进冲 pressure mold design

        冲 pressure mold design is combined is improve/increase pressure mold resistant use degree 基础. therefore, in design pressure mold for product formed in conditions has measures, improve/increase pressure mold resistant use degree, design small pressure mold lifespan performance in small 孔 凸模 upper. for/regarding this category of pressure mold, in design make fine small 凸模尽 amount shrink short its long degree, increase strong/high degree, meanwhile, also using/adopting toward sleeve/set methods add strong/high fine small 凸模进行保护.

         in addition, in pressure mold design upper, separation to 模架 形式, 凸凹模 solid methods and toward 形式, pressure in 心 确定 and upper, lower sheet/plate rigid property and other factors. especially for/regarding 冲裁模 说, 选取间隙 value for resistant use degree has very large effect/influence. in design 时, pressure mold need selection combined 理, its value can small, 否则会 effect/influence pressure mold use lifespan and resistant use degree. 实践证明, in effect/influence pressure parts quality lower, 适当放 large can large large improve/increase pressure mold resistant use degree, has 时甚至 improve/increase and 几十倍.

         positive selection pressure mold material

         different pressure mold material tool has different strong/high degree, tough property and wear resistance. in conditions lower use high grade material can make resistant use degree improve/increase good 几倍. therefore, is improve/increase pressure mold resistant use degree must need selection good material.

        Toolox series material, is types tool has high toughness, high wear resistance, basic has internal stress types hard new type tool 钢. but also tool has non high pure degree,晶粒 degree non fine small,S,P content non less,析出 carbon material content less, but also non uniform. due to formed separation design,Toolox series material tool non excellent surface treatment property can, its in Toolox44 nitrogen rear surface hardness can to HRC65 above,Toolox40 surface hardness can to HRC62 above,Toolox33 surface hardness can to HRC58 above, deep degree most high 达1.8mm.

        Toolox series material tool above features, make Toolox series material application in separation pressure mold has advantages.

        1) relatively thick sheet/plate (典 type 案例冲剪 thick degree is 35mm钢 sheet/plate),不锈钢 sheet/plate,以 and has color metal sheet/plate pressure molding mold, comparison type is 空调翅 sheet/slice mold and other.

        2) tensile mold,不锈钢 tensile mold.

        3) cold pressure mold. cold pressure 304不锈钢, thick degree 0.5mm above, 取代DC53 and other material,效果 non good.

        4) high dimensional stability requirements large type pressure sheet/plate.

         combined 理 进行冲 pressure mold parts and hot 处理

         in selection excellent pressure mold material meanwhile, for/regarding 同材质 and different property 质 材 material requirements combined 理 锻造 and hot 处理, is improve/increase pressure mold resistant use degree main/primary 途径之一. 例如, 淬火时, in add hot production hot, 不但会 make parts property large, but also in cooling easy deformation and cracking, make resistant use degree reduce. therefore in manufacturing pressure mold 时, must combined 理 掌握 hot process.

        Toolox材 material is 由钢厂直接预 hard 淬火调质钢, again need hot 处理, combined upper surface treatment (如 nitrogen 化),Toolox基体材 material high toughness,配 combined upper surface high hardness, can to excellent 效果.

         combined 理 安排冲 pressure mold manufacturing process and ensure processing degree

        冲 pressure mold processing degree for pressure mold resistant use degree effect/influence very large. in 冲裁模 in due to assembly non-uniform, in force function lower make 凹模啃 bad effect/influence pressure mold lifespan. meanwhile, pressure mold surface light degree low, make pressure mold resistant use degree reduce. therefore, in processing must need for large small, assembly 时凸模 for solid sheet/plate 支撑面 垂直 degree, pressure mold uniform and sleeve/set, 导柱 导 toward degree and other grade to separation attention/notes. manufacturing and assembly degree high and as separation surface coarse degree and other grade high, pressure mold resistant use degree high.

         positive selection pressure machine

         is improve/increase pressure mold resistant use degree, 应选取精 degree relatively high and rigid property relatively high pressure machine, make its pressure large pressure separation 之三十 above. positive 常 说, use 伺服冲床 can versus improve/increase mold lifespan in 几倍至几十倍 above.

         combined use and 维护冲 pressure mold

         is improve/increase pressure mold resistant use degree, as must combined use and 维护冲 pressure mold, for pressure mold 应经常进行 repair, anti pressure mold belt/tape as.

         above is 我们整理 improve/increase pressure mold wear resistant degree several commonly used methods, improve/increase wear resistant degree not only can let pressure mold use lifespan increase, reduce mold enterprise production cost, more can ensure production product quality, improve/increase production efficiency.
