92级了 去哪里升级 难道还是秃龙洞

Pillar of the new forging process= 220mm;, / D,. ≤ 25, / D. . 177/220O81 ≤ 2.5, so the 140mm × 170mm billet upsetting than meet the requirements of the head; AO a - 140 × 17023800mm. A cone rod to take the average cross-sectional area, namely: A8056mm, A/A23800/80562.95. So 140mm × 170mm billet forging more than meet the requirements of the Ministry rod. Material selection and processing of the material is 45 steel forgings, production,uggs kopen, requires the use of reasonable specifications of raw materials, to improve production efficiency, and ensure internal quality forgings. 250mm round finally selected material is the best option. 250mm round material with the West. The first fire time, cutting 240kg,doudoune Moncler, pulling into a 140mm × 170mm square steel, after cooling Saw cutting to 4; the second fire, time, steps stretching and throwing on the tip son broke the tail cone 68mm × 124mm × 320mm Taiwan: The third fire, time, light upsetting to remove oxide skin, into the forging die, upsetting and iron with the drive (on board) will be out of corners, and then repeatedly flipping forging die, forging the Ministry of the end platform, remove the air-cooled forgings. Deformation of the mold design mold pillar fell two main shank dies, the whole forming die shown in Figure 3, Figure 4. Selection of mold material mold is used in the 3t hammer, as long working hours in the 800 ~ 1O50cc, so the mold material should have high strength, hardness, impact toughness and high temperature, good thermal fatigue resistance, wear characteristics , and there are good processing performance. So the use of hot work die steel 5CrMnM0, heat hardness HRC42 ~ 45. Department of forging die structure design rod tip forming die for the child fell, the shape of the cone-shaped cavity,uggs nederland, the shoot tip level degree and should be the same forging die,tory burch shoes sale, forging die due to open on a part, you can not flip from the lower cast, so shoot to be the appropriate choice of degree, for ease of forging from the forging die after forming, remove, use tip 5 degrees. , The specific dimensions shown in Figure 3. The overall size of the cavity die forging forging forging heat map size, because the pieces of hammer forging in 3t, feed and the total weight of 200kg or more forging die, and the forging process requires three full-rotation direction, so that the mold by hammering six sides, flipping by manpower is difficult to achieve, and the operating machine Flip and can not gripping, and very unsafe, even if reluctantly operation, could easily lead to thermal fatigue of hot forging die. At the same time low productivity, increased fire times, difficult to remove oxide and affect the internal and external quality forgings. Based on the above reasons, Hongxing design and development company can be rotating out of the mold, shown in Figure 4. Structural characteristics of the mold are: (1) husband dies in the operating unit holders, using the rotation operating unit, the mold can be rotated to achieve full three-dimensional to meet 9o forging requirements. (2) To ensure that the mold can be easily controlled in the rotation process, the key is to determine the switching center of the mold and the mold and forging 0 P, the relative position of the center. If the center P 0 coincides with the center of gravity, the mold can be rotated around the center, in the forging process difficult to control, is not conducive to production. When the center of gravity P 0 at the center just below the mold rotates, under the action of gravity G to ensure the stability of motifs, in a natural sagging state. Take rotating, the manipulator arm clamp down and under the anvil can be achieved through controlled rotation center of rotation of the position of the mold tooling see map, as shown in Figure 5. The surface of the mold should ensure that sufficient commitment hit area. In order to ensure commitment on the side of the mold attack area and rotational positioning, an increase of lateral structure, as well as to ensure clamping lever to avoid hammering face, holding PLANE lower than the model of plane 5mm, shown in Figure 4. Forging forging deformation process the material forming process takes two fire times: the first fire time (1) take 295mmX17OmmX140mm’s (2), shoulder press, shown in Figure 6 (a): {3) are pulling pole, wrestling shape, see Figure 6 (b). The second fire times (1) Department of upsetting lever to remove the oxide skin, shown in Figure 7 (a): (2) upsetting the head, with a catch of iron (on board) broadening, shown in Figure 7 \) forging size 270mm, shown in Figure 8 (a): (4) forging size of 310mm, shown in Figure 8 (b); (5) formation; (6) forming, forging ministries to ensure that size, heap cold. Conclusion The analysis of the technology through the guide post designed a full range of rotary forging die can be filled forging die forging of such births in the gaps within the Ministry of Railways. In the production process,moncler homme, safe operation, flip flexible, low labor intensity, high efficiency, forging pass rate 1O0%. Proven, the mold manufacturing simple, long life, easy to cool, and low cost mold manufacturing, saving a lot of money, this process can also be used for forging axis of circular cross section level, so the mold structure worthy garden 相关的主题文章：ugg boots günstig Mold clamping technology introd ugg boots günstig Centre compaction forging proce magasin moncler Extrusion die design and metal buc

这个``个人感觉selectedhomme走商务男装路线，而jackjones走的是休闲路线，自然selected定位的年龄层都比jackjones高一些，有局限性，毕竟大多数人还是穿着休闲装的时候比较多，jackjones拥护者应该多一点
