Crankshaft forging process design patterns
Two groups, any groups can be selected as the benchmark Shui Po,adidas climacool chill, and the benchmark can be arranged in the mold can be arranged in the next model, shown in Figure 1. Cane crankshaft only has 1 set of benchmarks Shui. 2. Selected benchmark Shui principles (1) help to improve die life. (2) before forming easily locate billets (3) help to improve the ability of the metal filling. (4) a larger balance on the block with crankshaft, the baseline should be selected Shui Po group in the middle of the crankshaft, or near the middle of the Po shape is round or oval-shaped or not to open files with balanced block and Received Date : 1995 a l2-02fc) Figure l (a2.5 basis Shui Po. arrangements for the next model (b) 3 Po Po as the base arrangement in the mold. (c) l6 Shui Po as the base, arranged in the upper die 13 large crankshaft,adidas climacool hose, or may choose as the base ends of the crank Shui (5) simplify the mold structure, easy to manufacture. (6) the weak part of the mold should be placed on the mold (7) forming the crankshaft, the lower mold part of the previous model parts easy to mold. a 3 base Shui spatial location of the best types of structural type of the crankshaft, the best of its benchmark Shui spatial location as shown in Figure 2 to Figure 5. to shape the level of the crankshaft and its projection location map three-dimensional space groups, respectively, Po the location and main journals, connecting rod journal of the spatial position in Figure 2 for the three benchmark Shui Po crank the best spatial location map,adidas neo, and its basis Shui Po 2 Figure 3 for four Shui Abduction of the best space reference crankshaft location map, 1.4 basis Shui Po Figure 4 for the five benchmark Shui Po crank the best spatial location map, and its basis Shui Po 3 Figure 5 for the six benchmark Shui Po crankshaft best spatial location map, the 3.4 basis Shui Po 14 spindle scarves heart coil 2}. V.. Bu, located West ring 3 73 '/ l-map 4.16q120 , the parting line of the crankshaft to crankshaft parting with the structure type and structure of the trend line type of design level is directly related to the life of tooling, metal filling,adidas online shop, forging quality billet positioning, ease of stripping, mold making difficult Easy,adidas climacool schuhe, materials, etc., and therefore should be sufficient attention. 1 crankshaft parting line to determine the principles and structure of type (1) Minimize the gap: including parts of the spindle base Shui neck a connecting rod journal of a gap, Abduction of a gap, and other groups, as shown in Figure 6 (2) as it has a high strength tooling (3) formed by the parting line of the shape of locking more solid nature, and seeks to replace plus the lock. Lord , dent of the slope should be ≥ 7., ease of forging mold (5) of the parting line of the fillet by the general rules of design, but inside, outside cut, that is located outside of the mold chamber should be larger than the mold chamber round the corner, its many benefits, such as easy stripping, etc. (6) of the parting line to the formation of the bulge, dent, in the mold chamber should be as wide as possible outside of some help to improve the die life, was underway The role of natural lock shown in Figure 7. ~ 7 (7) by the parting line to the formation of the deposited material plus I (I block) should be as small as possible, but when the impact of die life, the amount should be increased over a large block (8) as the parting line to a simple, non-benchmark Shui Po on the medial and lateral parting line should be as small as possible to drop shown in Figure 8. Circle 8 (9) conducive to the blank position. (10) of the parting line of the line should follow the direction and structure of the mold type high life,adidas climacool, drop a small,adidas schuhe, gentle, easy to mold, I block the formation of small and uniform shape of the best lock, etc. 2. crankshaft parting the trend line in Figure 9 with the structure type 6 Shui crankshaft parting line to the typical, flat space location map. Kids in 9 Third,adidas la trainer, pre-forming die crank chamber and the final set of principles and their relationship forging die bore crankshaft mold in the general design, rarely with pre-formed mold chamber. whether to adopt the pre-forming mold chamber, the main structure should depend on the crankshaft with the actual situation and the unit 1. crankshaft decadent floor forming the setting of the original Ju Gang (1) crank with more (8 ~ 12) and a large fan-shaped balance weight, the mold chamber depth ≥ lOOmm, you need to set the pre-forming mold chamber (2) without the crankshaft balance weight, or its shape is simple, can not set the pre-forming die bore (3) units with a breakdown equipment have two side by side lot and 1St forging hammer, according to the structure of the crankshaft to determine the need for pre-forming mold chamber, such as only a forging hammer, and they need to crank pre-forming mold chamber, the only use of a multimode chamber die forging method 2. medullary crankshaft preform and final forged floor floor win the general relationship between the pre-forming die bore cross-sectional area should be larger than the final forging die horizontal bore cross-sectional area of 10 ~ 3O. For easy-to-shape cross-section (part) should take a small value, the balance of the block for forming hard, or easy-to-site defects should take large values.
