液压剪切机的设计

1第一章绪论11剪切机的类型、特点及选型用于对轧件进行切头，切尾或剪切成规定尺寸（定尺）的机械称为剪切机。根据剪切机刀片形状，配置以及剪切方式等特点，剪切机可分为平行刀片剪切机，斜刀片剪切机，圆盘式剪切机和飞剪机。按驱动力来分，可分为电动和液压两类剪切机。平行刀片剪切机两个刀片彼此平行。用于横向热剪初轧坯（方坯，板坯）和其它方形和矩形断面的钢坯，故又称为钢坯剪切机。有时，也用两个成型刀片来冷轧管坯及小型圆钢等。斜刀片剪切机两个刀片中有一个刀片相对于另一刀片是成某一角度倾斜布置的，一般是上刀片倾斜，其倾斜角为16。它用来横向冷剪或热剪钢板，带钢，薄板坯，故又称为钢板剪切机。有时，也用于剪切成束的小型钢材。圆盘式剪切机两个刀片均成圆盘状。用来纵向剪切运动中的钢板（带钢）的边，或将钢板（带钢）剪成窄条。一般均布置在连续式钢板轧机的纵切机组的作业线上。飞剪机；剪切机刀片在剪切轧件时跟随轧件一起运动。用来横向剪切运动中的轧件（钢坯，钢板，带钢和小型型材，线材等），一般安装在连续式轧机的轧制线上或横切机组作业线上。平行刀片剪切机根据剪切轧件时刀片的运动特点，平行刀片剪切机可分为上切式和下切式两G3835类。21G714上切式平行刀片剪切机G17837G12193剪切机的特点G4466G19481下刀G3278定G993动，上刀G2029是上下运动的。剪切轧件的动作G11013上刀来G4448成，其剪切机G7512G11013G7380G12628G2345的G7366G7576连G7450机G7512组成。G19512G1114剪切机G7424G1319G1055G3818，一般G17836配有定尺机G7512，切头G6922G19610G994G17767G17877装置等。G11013于下刀G3278定G993动，为G1363剪切G5049作G20046G2045进行，剪切的轧件G2414度G3835于G22G196G19G80G80时，G19668在剪切机G2530装G16786G6682动G2500或G6682动G17758G17959，其G7424G17535G7092驱动装置。剪切时，上刀压G11540轧件下G19489，G17855G1363G6682动G2500也下G19489。G5415剪切G4448G8617，上刀上G2331时，G6682动G2500在其平G15925装置作用下也G3250G2331G14279G2419G3999G1313置。此类剪切机G11013于G13479G7512G12628G2345，G5203G8879用于剪切中小型钢坯。此G3818，随G11540G5567G17907G6454刀的G10995G1147G19668G16213，也G1998G10628G1114G14033G5567G17907G6454刀的上切式平行刀片剪切机，用来剪切初轧钢坯和轧板。G5415G9994，其G16786G3803G18337G18339G1262有G17751G3835的G3698G2164，G13479G7512也G12257G3809G7446G1135。G21G17下切式平行刀片剪切机G17837G12193剪切机的特点是上下刀G18129运动，G1306剪切轧件的动作G11013下刀来G4448成，剪切时上刀G993运动。G11013于剪切时下刀G2500将轧件G6272G12175G17758G17959，故在剪切机G2530G993G16786G6682动G2500，G13792G1000G17837G12193剪切机的机G7562G993G6227G2475剪切力。G11013于上G17860两个特点，下切式平行刀片剪切机G7234G17953用来剪切中型和G3835型钢坯和板坯，以G1955G17743G6984个剪切机组的G16786G3803G18337G18339。第二章液压剪切机的设计计算设计参数剪切机型式G8845压小G17722G12239动式G15999剪钢坯断面尺寸G4381G27G19G1041G27G19G80G80G104G80G80G43816G24G104G21G21G24G80G80G104G80G80G1207G15932钢G12193G52G21G22G24G16G36G21G26G54G76G48G813剪切G9213度G305G26G24G19G263G6301坯G17907度G21G80G18G80G76G81剪切小G17722及横G12239G17758G17959G18337G183391G26G17G27G55钢坯定尺G19283度G21G17G24G8021剪切机结构参数的确定211刀片行程刀片G16757G12651公式HHFQA1QA2S（G21G161）式中H刀片行程（指刀片的G7380G3835行程）；HG15999切钢坯的断面高度，G17837里取H1G27G19G80G80；F是为G1114保证钢坯有一G1135翘头时，仍G14033通过剪切机的必G16213储G3803，通常G24G19G26G24，G17837里取6G19；QA1为G1114避免上刀片G2475钢坯冲撞，G13792G1363压板低于上刀的距G12175，QA1G24G24G19G80G80,取QA1G21G19G80G80S上下刀片的G18337叠G18339，取SG24G21G19G80G80,G17837里取S1G19；QA2下刀低于G17758G17959G15932面的距G12175，QA2G24G21G19G80G80,G17837里取QA2G21G19；故有H1G27G196G19G21G19G21G19G21G19G22G19G19G80G80刀片行程关系如图G21G161所示4A0A3A3A4A4A5A6A7A8A9A10A11A12A8A9A7A13A7A8A10A11A12A8A5A4A14A8A15A3A4A16A8A15A17A17A4A4A18A19A18A19A18A19A15A15A20A20A4A4A21A22212刀片尺寸的确定刀刃长度因为所G16786G16757的方坯剪切机，G1000属于中型剪切机（PG21G17G24G27G17G19），所以剪刃G19283度按如下公式G16757G12651L（G21G21G17G24）BA23A24A25（G21G16G21）式中L刀刃G19283度，G80G80BA23A24A25G15999切钢坯横断面的G7380G3835宽度，G80G80；取BA23A24A25G21G21G24G80G80G2029L（G21G21G17G24）BA23A24A25（G21G21G17G24）G104G21G21G244G24G19G246G21G17G24G80G80，取LG24G19G19G80G80刀片断面高度及宽度HG19G176G241G17G24HG21G16G22BHG18G21G17G24G22G21G164式中H刀片断面高度，G80G805HG15999切钢坯断面高度，G80G80B刀片断面高度，G80G80G11013钢坯断面尺寸G4381G27G19G1041G27G19G80G80G104G80G80G43816G24G104G21G21G24G80G80G104G80G80G2029HG19G176G241G17G24HG19G176G241G17G24G1041G27G1911G26G21G26G19G80G80,取HG211G19G80G80BHG18G21G17G24G22G26G19G274G80G80取BG26G19G80G80G7380G2530根据G15932G27G16G21（轧钢机械（第三版）PG21G249）剪切刀片的尺寸G7380G2530确定为BG104HG104G26G19G104G211G19G104G27G19G19G11013（G15932G27G16G21）确定的热钢坯剪切机基G7424参数。如下G15932A26A27A28A28A29A29A30A31A32A33A34A35A36A37A38A31A32A33A34A36A37G7380G3835剪切力G48N刀片行程G80G80刀刃G19283度刀片断面尺寸理论空行程次数次G18G80G76G816G17G22G22G19G19G22G19G19G26G19G104G211G191G2116213剪切机理论空行程次数剪切机的每分钟理论空行程次数G1207G15932G1114剪切机的G10995G1147率。理论空行程次数的提高G2475到电动机功率和剪切机G13479G7512形式的限制。理论剪切次数是指每分钟内剪刃G14033够G993间断的上下运动的周期次数。因此，G4466G19481剪切次数小于理论空行程次数。依据G16786G16757G16213求和轧钢机械（第三版）PG21G249G15932G27G16G21，选择理论空行程次数为1G2116次G18G80G76G81。622剪切机能力参数计算221剪切过程分析轧件的G6984个剪切过程可氛围两个阶段，即刀片压入金属G994金属滑G12239。压入阶段作用在轧件的力，如图G21G16G21所示。A39A40A41A40A42A43A44A45A46A47A48A44A45A46A47G5415刀片压入金属时，上下刀片对轧件的作用力P组成力矩PA，此力矩是轧件沿图方向转动，G13792上下刀片侧面对轧件的作用力G55组成的力矩G55C将力图阻止轧件的转动，随G11540刀片的逐渐压入，轧件转动角度G993断G3698G3835，G5415转过一个角度G2530便停止转动，此时力矩平G15925，即PAG55C。轧件停止转动G2530，刀片压入达到一定深度时，为克服G1114剪切面上金属的剪切阻力，此时，剪切过程G11013压入阶段过渡到滑G12239阶段，金属沿剪切面开G3999滑G12239，直到剪断为止。222平行刀片剪切机的剪切力与剪切功剪切公称能力的确定7剪切机的力G14033参数包括剪切力和电机功率。剪切力是剪切机的主G16213参数，驱动剪切机的电机功率及剪切机主G16213零件尺寸的确定，G4448全G1363用或充分发挥剪切机的G14033力G18129G994剪切力有关。在G16786G16757剪切机时，首先G16213根据所剪轧件G7380G3835断面尺寸来确定剪切机公称G14033力，它是根据G16757G12651的G7380G3835剪切力并参照有关标准和资料来确定的。1）G17G5415轧件材料为G52G21G22G24G16G36时G7380G3835剪切力为PG80AXG46G103G180G80AXG103G41G80AXG21G16G24式中G41G80AXG15999剪轧件G7380G3835的G2419G3999断面面G12227，G80G80G180G80AXG15999剪轧件材料在相G5224剪切G9213度下G7380G3835的G2345G1313剪切阻力，G48PA根据图G27G16G26G17A（轧钢机械），取G180G80AX1G19G19G48PAG46G13783G15397G11013于刀刃G11964G19057G451刀片间G19565G3698G3835G13792G1363剪切力提高的系数，其数G1552根据剪切机G14033力选择，中型剪切机，G461G17G21。按钢坯断面尺寸G4381G27G19G1041G27G19G80G80G104G80G80G41G80AX1G27G19G1041G27G19G22G214G19G19G80G80A49按钢坯断面尺寸G43816G24G104G21G21G24G80G80G104G80G80G41G80AX16G24G104G21G21G24G22G261G21G2
