College of Vocational and Technical, Mianyang 621000；2. College of Mechanical Engineer, Chongqing University , Chongqing 400030)Abstract Based the analyzes of theshearing strength, a new type of HC520- 3 hydraulicscissorshas been designed, include the main geometry parametersastructure parameters. This new type of hy-draulicscissors can satisfy the procedure of sample in the product line of steel rolling. It has beenproved that the hydraulic scissors can cut chromic stainless steel and alloy steel hereinafter 520mmquickly. The economy benefit is prominent.Key words hydraulic scissors,shearing strength,design LF3V,1|_AbF/H,|*,?aoZTb+Yv3aDaH,1p,|Nb|Vo?fwVJ,Ho?fw!as,；T_byN,3fM1pLALgMb,-S=PLgM(gq,NLbHC520- 3Ag,131p,A)|5,4,!,Hh!_#THW,iO!q#h,V73blM!7,S=1MAgTb-5e,?M?,varq,Oyxa.20bAgTha,8aQaFB8T,T4rq,THq,v7(PHH,HD2DMPHT,4D3_HD2,K,Q,g5d,M7b2 Ag1+j92.1 Ag9AggMH,gM?3BgMbAL13aaaD#,n|45a40Cra20CrMnTia38CrMoAla1Cr13a3Cr13a4Cr9Si2a4Cr10Si2MoaNAK80bgMQ, S= Q/ A SQ A # S= P#d24 # S (1)T Q ) )g,N；S)g,N/ m2；A ),m2； S ) )g,N/m2；d ) ),mb!9Agg,1XgMKSs,SSsbKvg,gMKSs%yKDs1:Ss= 0. 5Ds (2)T Ss ) )gMK,N/ m2；Ds )%yK, N/ m2bA820a35a45|5by20|,O?,bcaha5h9qoH,5o?z35|,YFbBf/,(45|,i241 285 HBb89VaMqbVZG35B,MVHT200HT350W+|oMb+yf/,VhbLb,L35a45|；b35a45|5b,|Ag45,iLbH,InAgX,|!9B8b2. 2 AgA=D9Vm2AgAdmV,AgVBgbyN,1LBLCbAgB,YVwMb5)TH,#EY,s1TwF1MF2,=Z_MQ,AgF,F= F1- F2 (3)T F1 )Aw；F2 )Mb7F1 F2,#A=H,#27#6 Sichuan Metallurgy|F29bF UF1F1= PA 103 ( 4)T F1 ) )Aw,KN；P ) )T,MPa；A ) )T, m2, A= P#D24 ；D ) ),mb2.3 Ad91p9,ea9bNH:d 3. 57 10- 2 F D ( 5)T D )MPab3 Ag?93.1 A9T= 60 QA ( 6)T T) ), m/min；Q )()A, m3/s；A ) )T, m2, A= P/4D2；D ) )A,mb3.2 ATHWATHWt:t= VQ = A SQ ( 7)T t ) )ATHW,s；V )A,m3；A ) )AT,m2；S )A,m；Q )()A, m3/sb3.3 A%A%V:V= A S ( 8)T V )A%,m3；A ) )AT,m2, A = P/ 4D 2；S )A,mb3.4 AqAqN:N= FT ( 9)T N )Aq,KW；F ) )A,KN；T) )A,m/sb3. 5 cC9C9,NH5,6:D= PyD(2. 3 R- Py ) 7+ C (10)T D) )Ac, m；D )A=,m；Py ) )L, MPabTP 16MPaH, Py = 115 P；TP 1616 MPaH, Py= 1125 P； R ) )8,Mpa；Rb ) )8F,MPa；n ) ), n= 315 5,B|n= 5；7 ),5, 7 = 1；C )9C#KF,YSb4 L#YV!9sn,!9HC520- 3Ag,mnm4bm4 HC520- 3AgLT,Ag?ygM520 mm/#,3P,i|zrTbA|,AV,7O?z!,|z6rm rmbID1.N7.Ag9!9.?v, 1998, 31(2): 155 1622.cJ, q.5A. ,
