Key. words: staJ ~ esssteeI: modelmatefi8l: cutmould Figure 1 shows a country's toy exports to the train tracks, a straight track as shown in Figure 1a. Also shown in Figure 1b arc curved track. The cross section shape shown in Figure 1c shaped, made of stainless steel rolling 1Crl8Ni9Ti profiles. This material toughness, high strength, thermal conductivity, are difficult to machine materials, and track length of the two end must be smooth to ensure that the two tracks, smooth connection. Make the connection at the train wheels, the cast has stopped, beating phenomenon. Track profiles will be cut to desired length,[link widoczny dla zalogowanych], if the use of saws or other mechanical cutting tools to cut off, it is very easy to produce high-temperature heat, the formation of tumor stick blade on the knife, so that edge will soon wear, blunt, there fight knife phenomenon, and very smooth cut surface, resulting in a lot of glitches, you need to be removed manually fee work harder, reach the quality requirements and production efficiency is very low, not mass production, has become an urgent need to address the technical problems . a straight track rail car parts r solid profiles 1A sectional dimensions Received Date :2001-014) 5 About the author: Lee Team (1956 a),[link widoczny dla zalogowanych], male, Hunan Qiyang, engineers, mainly engaged in metal stamping technology and touch with the Ai account aspects of metal forming process, METALFOI'd, IINGTEC1 {NOLOG \№ 620012 2.1 shear mold design mold structure and principles for the condition, design and manufacture of stainless steel as shown in Figure 2, shear modulus shaped profile, so that is cutting edge profile in the fixed mold 2, activity 3 cavity mold edge closed up, it differs from traditional open-type activities, the general mode of the free shear blade, fully enclosed with a smaller gap is to prevent the process of profiles in the shear deformation produced a result so the shear collapse angle wife. The working process of the mold is: first to teach anyone to fixed blade shear modulus profile 2, the activities within the edge mode 3, when the downward movement of upper die 4, the equivalent of a hammer tapping mode 3 active edge, forcing the active blade model 3 down movement, then was cut edge profile relative to the fixed mold 2, shifted, so that the cut off. In the shearing process, the profiles did not produce deflection, the shear surface very smooth,[link widoczny dla zalogowanych], no obvious glitches and fallen angle, to meet the foreign requirements for the factory to create a considerable economic benefits. Figure 2 profiles shear modulus 1. Positioning block mode 2, 3 fixed blade edge mode 4 activities. 6 5 cover on the mold. Sections were cut 7. Before (after) baffle 8. Right side of the baffle 9. Bomb off the top 22 mold use, maintenance and precautions when asked to use the mold over a period, if the blunt edge El, you can model the fixed blade 2, activity 3 blade model using the other side turn over, if both sides are dull, and then on both sides of the surface grinder to repair a blade,[link widoczny dla zalogowanych], and the thickness of the corresponding front baffle 7 wear thin, the thickness is equal to the thickness of the active edge of mold with cutting the gap 3 (z is 0.05 ~ 0.10rmn). Mode 3 edge assurance activities can slide up and down tray benefits. We must ensure that sections can be cut back feeding interests,[link widoczny dla zalogowanych], but also the red cross-section of small glitches, you must be a fixed blade module 2 (see Figure 3) and active blade model 3 (see Figure 4) of the cavity in the initial position consistent, that is, in Figure 3 26, I5 and in Figure 4 26, I5 size does not allow dislocation. Line cutting the cavity, the cavity size of the largest physical size than the profile section (see Figure lc) can be a little larger; if the arc punching Figure lb Figure 3 Figure 4 Activity of fixed blade edge die mold shaped curved track, then but also in the warp direction (ie Y direction) with the bow high △ size (see Figure lb). IEI mold cavity dimensions shown in Figure 5. Figure 5 mold cavity mouth size of addition, according to the needs of cross-section, you can choose Figure Ic's, Y punching profiles placed in different directions, as shown in Figure 5,4 A release hole or holes, to obtain the desired direction of the ideal profile. Specifications of different lengths to ensure that the sizes of materials to be in the fixed mold 2, the expected edge direction (ie left) the installation of the adjustable positioning loop 2 shown in block device 1.3 Conclusion The production-proven, this shaped stainless steel shear modulus profiles using the easy maintenance, operational safety, product quality, production efficiency increased more than IO times cutting.
