In addition, the virtual axis machine tools can be gradually improved as the processing center. Its working space for the three largest sphere radius rod length, rod length of 3 months minimum radius of spherical joints with three Hooke most working space Figure 53 A.3 spherical radius of the smallest part of a long rod B Hook cone hinge formed part of the largest swing angle C3 part of the largest sphere radius rod length required under the operation process ≥ ... (2 a minimum rod length) of the effective work space, select the appropriate internal work area, such as cylinder,[link widoczny dla zalogowanych], rectangular,[link widoczny dla zalogowanych], etc., suitable for a variety of operating forms. this can make full use of non-processing area (Figure 6,[link widoczny dla zalogowanych], 1,2,3) place tool changer. 3 Results Cambodian language paper based virtual axis machine tool designed to mold CAD / CAM system the following advantages: ① Chinese interface operation (I touch with industry) 1999No.9 total 2239 Vacuum tube drawing die design standards Jiang Automobile Co., Taiwan Fertilizer Boat Division (Hefei, Anhui 230022, China) Yan Chen Niao Abstract] Vacuum tube by pulling on the HFC1061 Stress and strain analysis extended into Tong, Chung-forming master pulling stress and strain, and identify parameters and the arts I die structure design, product quality improved significantly. Keywords Vacuum tube drawing die STRESS BOUNDARY 1 Introduction Figure 1 is HFC1061 car a vacuum tube, material o8 steel, material thickness 1.2ram,[link widoczny dla zalogowanych], the part is a cylinder with a flange parts, the bottom part of the spherical surface. stretching the beginning, the middle part of the punch and rough contact in the convex and concave mold great gap free surface, material is not oppression ring to suppress the majority, it is easy to prevent wrinkling wrinkling, need to increase the BHF. but too much is not suitable for BHF Figure 1 Vacuum tube Received: January 29, 1999 ● ● ● ● Female Female Female ● ● ● ● ● ● j * ● ● ● for convenience; ◎ on common hardware,[link widoczny dla zalogowanych], lower cost; ③ modular design strong expansion. In short, the virtual axis machine tool die CAD / CAM system has broad application prospects. References l River Vision statement. a major innovation in the machine structure - var {ax machine came the World Manufacturing Engineering & Market .1995 (1 ): 16 ~ 17, it not only part of the thickness of the severe thinning of parts, sometimes resulting in stretch forming can not be successful, the damage caused by stretching and cracking of rough pieces. By the time the pieces of tensile stress and strain analysis, through the mold structural design and process parameters to control the stock to determine when the stretch forming of metal flow, which effectively prevent the pieces of wrinkling and cracking when stretched, to ensure product quality. through the process calculation, part blank diameter Do = 420ram, the relative diameter of the flange 258/228 = 113. by the stamping information look-up table was designed for the ultimate tensile coefficient 0.54, taking the die radius r: lot = 12mm, to determine the part drawing process is shown in Figure 2 instructions. the part stretching factor 228/420 = 0.54, equal to the ultimate tensile factor 2 should be used by conventional stretch forming have a good chance, but we only used one time stretched shape. 2 flange deformation areas of stress and strain analysis and measures to prevent ruffling 2MartinEastmanWittHexapodGo | romSh-owFLoortoShopFloor?
