Wide Flat Anvil Ring Forging Forging round

Long, cutting 1.71 upsetting high l130ram,[link widoczny dla zalogowanych], the cross section increases, the temperature dropped. No 21220 ~ 1100 ℃ 165 law continue upsetting. 31220 ~ 950 ℃ heating recycled upsetting, red L15141220 ~ 850 ℃ to expand L,:: I: b450 and flat face 146 stretching l4451200 ~ 850 ℃ when the core offering of stretching to 1150. Reaming reaming to about O6O0 ll261150 ~ 850 ℃ when the wide flat anvil reaming to 1.3 in the 780 and the flat end to the wide flat anvil forging reaming size, the mandrel 5 fire stretching 7l100 ~ 850 ℃ when the end of the wall cracks, finishing cylindrical size, enlarge size of a high degree of 1.27, and flat face ① crack (length 50ram, deep 30ram) ② folded (about 200ram arc length, depth 20ram) Figure 5c) with wide flat anvil reaming, simplifying procedures,[link widoczny dla zalogowanych], reducing time and forging fire times, lower costs, and forging the appearance of straight, to solve the multi-anvil expanding height among the problems is easy to produce depression; d) ingot-type selection table management, improved ingot utilization ; e) forging process is the major reaming, the internal organization of forging significantly improved the quality of ultrasonic flaw detection is l2 ・ ideal. Fully comply with Taiwan JB4726-94 (pressure vessels and low-carbon steel forgings magic \weight; second mandrel pulling one end of the inner wall of long cracks; b) the fire is still above normal times, a total of 7 times the fire the fire because of inadequate capacity 25MN hydraulic press: c) as punching a smaller diameter, 4 thermal expansion hole at the small end of the mandrel break. 5.3 improvement assumption a) long with a mandrel pulling down v-type anvil. This can improve the stress state, reducing the tendency of cracks and improve efficiency; b) risk-free VI ingot can be directly upsetting hollow punch after punch, which can increase the punching diameter, and further improve the utilization rate of steel ingot. Cutting process due to the reduction and reaming after punching process, it also reduces the forging process, reduce the forging fire times, these are also reduced under the material (ingot) weight, and thus greatly reduce the cost of forging. f turn 7), Science & 3 / 2000 figure was six boards for the red start equatorial first decile, and other segments of the center of the sphere corresponding to equal angles, considering the precision cutting crossed, generally at lO0mm a 120ram decile, Expand by way of approximate expansion cone shown in figure VI. The equatorial horizontal and vertical length, to suppress deformation after different dimensions, horizontal as small size, generally started by one of the layer position. In the longitudinal elongation after the suppression of large diameter size can be started. The position of neutral layer can be selected based on experience, or blunt edge position determining groove, because too many segments, usually calculated by computer programming. The formula for the cone expansion formula, in this state is not tired. The spherical tank is divided into five panels 2000m: equatorial, temperate board, the board very, very 5 board will be very sides. Except for a very sides, the other equatorial several board uses the same methods with the start. For the very edge of plate to start, because of its asymmetric shape, making the choice of the reference point after forming is difficult, only leave enough margin, by first determining the shape a little after the A4, then the value determined by the chord length A2, A3, A5 arc length of each point measurement, by comparison with the theoretical value adjustment to the shape of the point determined. Because this method is the first time, the error is too large, it is more adventurous,[link widoczny dla zalogowanych], there are other better methods should be further explored. Is the approximate size of the expansion is required in the production process pressure was measured according to chip the ball to adjust the size,[link widoczny dla zalogowanych], measure the pressure after the ball size pieces meet the requirements of the drawings. NC program data adjustments and the preparation of practical work experience required in these areas greatly helped by other colleagues, to express my sincere gratitude. (Then 12) 6. Conclusion With the gradual improvement of the socialist market economy, with the international business exchanges. A business foothold in the market stand hidden, well able to grow in the market, price competition has been impossible to achieve alone: we think. Market demand is our direction. Therefore, efforts to tap the potential, innovation is the foundation of the enterprise. Through this process of innovation,[link widoczny dla zalogowanych], to personal experience to: Canton, Science & Technology 3 / 2000 technical innovation, process innovation, not only for our competition to win opportunities in the market, but also to save energy and create enormous social benefits .
