Banban Bending Die Parts of different materials the minimum bend radius,mac cosmetics wholesale, bend parts to avoid cracks or broken Received: June 7, 1996 c - C. r ~ crack. When the convex and concave side mold space is equal to or slightly less than the z component material thickness or use the work of smaller punch radius, the bending part can effectively control or eliminate the springback deformation of the plastic bending process. 2 Design of the main parts of each punch 2.1 punch design has many different radius,ed hardy mexico, form a series of small to large. The radius-one correspondence with the part material thickness,mulberry norge, that is O,ed hardy schweiz, 5rim <t ≤ 1. Hiss ml, r = 1.5ram; 1. Ikima <≤ 2. , R = 2.5mm; 2. <≤ 3. Ikima, r: 4.01Jma; 3. Ikima <t ≤ 4. Ikima, r: 5.0ama; 4. Ikima <≤ 5. Ikima, r: 6.5a-an; 5. Ikima <≤ 6. , R: 8.0rea ~; 6. Ikima <≤ 7. Cries of m, r: 9. Hiss m; 7. Ihra ~ <l ≤ 8. Cries of m, r = 10.5mm. Convex, engraved die radius values corresponding parts on both ends to facilitate selection. 2.2 die die design for each different radius, formed by the series is too small, and correspond with the part material thickness, that is 0.5mm <≤ 2. Cries of a twenty l, R: 5n-an; 2. Hiss】 twenty l <≤ 4. Ikima, R: 9nml; 4.0 <≤ 6. Ikima, R: llvta-a; 6. th ', m <' ≤ 8.0ram, R: 13mm, in order to meet the needs of bending process. Both ends of the central design of the die groove-oriented, its center surface and the center plane of the side baffle re-sets the width of the side guide groove width equal to the bezel. 2.3 The adjustment plate thickness adjustment plate formed a series, according to laga, 2ram, 5mm, 10mm design, combined to meet part A of Figure 2 the value of their various needs. Mouth Bu 2. 1997. N02 General l9. Zhou Dian, withered 3l3 application example shown in Figure 3, after the tractor Cong Results on board is an important part. The piece with the frame after welding machine must be met for the final assembly of the interchangeability requirements for transmission box, which must meet the required Parts of the technical conditions. This part in the sheet metal bending process on the bending die. The location of the die fastening to the maximum working radius optional Rllmm, punch fillet radius under the part material thickness of white m, choose r ~ ffl: lrfl. In this regard, the specific use of flexibility is required, that is, in part, and bent parts of the structure does not appear to allow the crack and fracture cases, smaller punch radius work. A plane bending to 4 14. Bai Shan 1 Hole, every bend 2, the top piece board design pin, can effectively control the hole margin, the total elimination of quality problems. Convex, surface loop 3 die after the links between the side plates gap thickness at the lower part selection bias, check GB70C ~ 88 standard, select Z = 5.4ram, determined by adjusting the wedge. Some site commissioning tensile modulus by Dandong Automobile Factory (Liaoning Dandong 118008) Zhang Xuemei 1 Introduction a mold is qualified, the most effective way to test to see whether the suppression of qualified parts. In the mold manufacturing process, due to the level of mold designers, mold and die machining technology fitter assembly and many other factors, made use of mold and mold the ideal state there will be some differences. The difference of the mold, in particular drawing a great influence on normal mode, only through the site commissioning of the mold. To identify problems and resolve and, ultimately, the satisfaction of parts. For the tensile modulus of the commissioning, the first stretch should be clear that all parts of sheet metal parts in which the tension stress state, through the correct analysis of stress state, the use of deformation zone will be a weak area, we must first deformation of the weak areas criteria to analyze specific issues, identify practical solutions cut Taiwan. Flange of the box is shaped to bring an example to illustrate the tensile pieces. Received: July 5, 1996 inspection,-q 'js. Competition in the tensile deformation of main parts of the flange at the corner, by the tensile stress, tensile pieces of possible defects have the following main categories: (1) drawing parts and corner parts of flange wrinkling near the wall resulting corner cracking phenomenon, shown in Figure 1. (2) tensile flange in the corner late in cracking phenomenon, shown in Figure 2. O ring a corner knife edge flange wrinkling and cracking (3) straight edge wall is easy to produce the phenomenon of slow song, as shown in Figure 3 相关的主题文章： magasin abercrombie christian louboutin alexa mulberry with elements drawn desert |
