Guide post 17 up and down the guide sleeve 58 consisting of two pads within a confined space, the pressure increased rapidly. In the rubber necking and discharge pressure and the formation of the axial spring force,hollister euroma2, the expansion of the middle of the waveform. Finally,ralph lauren, the model with the slider up, the workpiece under the action of the spring, from the upper concave mold play, the workpiece can be easily removed. 2. Included on the die die die,abercrombie madrid, concave mold, materials T10, hardness HRC60 ~ 65 on the concave cavity of the mold in maximum diameter (maximum diameter corresponds with the part) at the horizontal mode. The die cavity diameter equal to the straight wall part of the minimum diameter corrugated sleeve; take into account the size of the tube outside diameter tolerances, straight concave mold cavity wall part of the inner tube diameter to take the upper limit. Specific dimensions shown in Figure 3. △ l ~ 420.3l/3.2L- a 0.2l Day 140 (a) (b) Figure 3 combined necking die bulging (a) concave mold (b] on the die 3 soft soft punch Punch material is black rubber or polyurethane rubber. To ensure the correct shape after forming part of the waveform and smoothly removed from the corrugated sleeve, made of soft punch ladder-shaped,abercrombie hamburg, as shown in Figure 4, while, in order to store 4 software punch forging technology (4) 2001 aluminum alloy radiator stamping die design features of the computer,mulberry, Guangdong University of Technology Institute of Materials and Energy (510643) Xiaoxiao Ting ~ Liaoyi Juan Kuang Weihua Zhang Zheng-rong Sun Yousong summary of the computer with a high crest radiator red aluminum alloy sheet cutting mold design and mold characteristics precautions Keywords aluminum alloy computer radiator Die I. Introduction In order to improve the working environment computer components,hollister roma, computer time to ensure continuous and stable work and life,hollister frankfurt, the current host computer boxes are equipped with radiators,ralph lauren sverige, radiator called the computer Computer output of the radiator increases with the growth in computer production, growing demand for precision and mass production to meet the needs of the radiator on the computer L and the gap on some of the other processing, using stamping methods of processing,hollister dortmund, is considered the ideal processing solution. However, the radiator is a computer chip with a high dark parts, and compared with ordinary sheet metal stamping It has different characteristics. to understand and master these characteristics are conducive to rational design and manufacture of molds, molds for improving the quality of life and computer radiators are of great significance in view of the computer radiator punching a short history, has not yet experience in this area to see the introduction. To this end, we developed computer programs and radiator design and manufacture of stamping dies to some of the experience described below, for the peer reference. Second, the structural characteristics of the radiator and processing * This Imperial College has been Mould Technology, Huazhong Science and Technology State Key Laboratory of funding ** male child,hollister online shop, 53 years old. Associate Professor Received date: 2091 <) 3251. Structural characteristics as aluminum, light weight, thermal performance, and easy processing characteristics. So now the computer mainly used in aluminum heat sink material. Its structure, mostly high ridge sheet. Figure 1 are two computer radiator parts diagram. Figure la in which the flat-shaped radiator, Figure 1b shows a coronal radiator. Their shape are different, but are grown on the bottom plate is installed or foliage-like or narrow strip of dark spoke-like film. 2. Processing computer processing radiator forming the main line of the following processes: extrusion length (cut off) profile ditch a blanking (punching, cutting head, red gap, etc.). Third, stamping die design features of the computer radiator radiator according to the structure of the computer, materials and process characteristics. Mold design and manufacture of the following issues must be special attention: 1. Correct choice of punching direction of the radiator shown in Figure 1a, when blanking piece from the ridge side of (Jr surface) or washed down from the back (below) washed up? Choose a different direction blanking, punch and die design varied. In order to ensure the reliability and service life of mold. The use of punch from the top is more reasonable. This will not affect the thin edge die mold life, for the long ridge piece punch punching prevent problems in forming a soft punch can produce enough pressure, should ensure that the volume compression of the rubber volume Vl a where t is the soft punch volume, mm. Volume of the corresponding part of the tube, m a soft punch volume form factor: For polyurethane, a 1.165 ~ 1.175; black rubber for a 1095 ~]. tOZ. Fourth, the conclusions set of composite waveform model structure is simple, easy to operate and improve production efficiency} combined necking a bulging, the deformation zone stress state is good. Strain distribution is reasonable (compared with the natural bulging ridicule). References 1 Zhang sulfur automotive design Beijing: Mechanical Industry Press, 19992 Wang Tong thumb.
