(One model of 1) is much one model much forge can raise forge the use function of forging die and economy and forging efficiency, but also can increase forging die dimension and equipment tonnage, when forging die dimension and equipment tonnage are insufficient, bring about figuration extremely easily to be mixed hard forging efficiency is low. Timing hammer is sheet weight <0. The small-sized model forging of 2kg (1) seeing a picture, the spare parts uses Gh4080a of alloy of high temperature of alloy steel 12crni3a~ two kinds of material, means of figuration of its die forging has apparent difference. The tie condition of figuration of 12crni3a steel die forging is little, sex of die forging craft is better, appropriate one model is die forging of many forge, tune, successive much forge and many add up to forge to wait. When one model much forge, can realize one makings two forge or makings 3 forge; Or when much forge of model of the another after tune die forging, can realize one makings 4 forge or one makings 6 forge. The tie condition slue of figuration of die forging of Gh4080a of high temperature alloy, if plasticity is low, be out of shape fight muscularity, conglutinate muscularity, right heat rate sensitivity is strong, forging temperature range is narrow, from beginning to end forge temperature asks strict, heat conduction leads low, corresponding speed change rate and stress condition sensitivity are strong, cold make sclerotic trend apparent, recrystallization, extreme difference of sex of die forging craft, unsuited die forging of one model much forge, tune, successive much forge, compound die forging adds up to forge to wait with many, expect aptly only one forge. > (2) is successive much forge points to in same cover forging die admiral ≥1 of die forging of section of a preform reoccupy cuts off impression to cut off this forging depart from preform after forging, ordinal forging again and cut off depart again in order to obtain ≥3 the method of figuration of a kind of die forging of forging. Successive much forge but sufficient and effective use clamp collet with managing raw material, but the forging temperature of final take shape is inferior and cut off not easily, can affect forging quality again, forging efficiency and forging die service life. Bearing pin forging (2) seeing a picture is successive the working process of much forge is: Unplug grow to boil crowded one eventually everything breaks forge to unplug grow to boil crowded one eventually everything breaks forge to unplug grow to boil crowded one eventually forge, depend on the 1st paragraph of preform first namely second unplug long, boil squeeze and eventually forge, be in the 1st forging of figuration next cut off cut off on impression; Depend on the 2nd paragraph of preform again next second unplug long, boil squeeze and eventually forge, be in the 2nd forging of figuration next cut off cut off on impression; Depend on the 3rd paragraph of odd preform again finally second unplug long, boil squeeze and eventually forge. Bearing pin is successive much forge can realize one makings 3 forge, but utmost ground reduces clamp collet volume. (3) tune die forging points to be in same cover forging die admiral a preform first ≥1 of die forging figuration forging (or first figuration preform one part) later again die forging of forging around tune again figuration ≥1 it is another forging (or epigenesis form preform another part) in order to obtain ≥2(. Tune die forging but sufficient and effective use clamp collet with managing raw material, forging efficiency is taller, but forging preform is in the temperature after tune is low, have certain effect to forging die service life and forging quality. Join head forging (the working process of die forging of tune of 3) seeing a picture is: Unplug long one eventually forge one tune eventually forge, will unplug partly among preform first namely after growing again the half preform eventually forge figuration is a forging, next reoccupy forceps clips forging around tune the other in part preform eventually forge figuration is another forging, expect in order to come true two forge. Die forging of join head tune can achieve the small collet that do not have clamp, forging service life of tall, forging die reachs efficiency high fruit of good equivalent of forging quality consistency. (4) compound die forging points to be in a preform a forging die last time the gender is compound after die forging figuration in order to obtain ≥2 (kind) the method of figuration of a kind of die forging of different figure, dimension and function forging. Compound die forging but utmost land increases forging overall material utilization factor, have " investment is the smallest change, reclaim use the biggest change, resource energy utilization rate is the oldest change and the smallest to environmental change change " characteristic. But the appearance of figuration of compound die forging and dimension match big forging and small forging harder. Gear is compound die forging figuration (the process of 4) seeing a picture is: preform 1 compound die forging is gear forging 2, pinion forging 4 with nut spacer forging 5. Compound die forging realized gear to expect 3 forge, accord with circular economy to output from the input " decrease quantify, recycle and recycle " 3R operates a principle, can reduce raw material to use up 12 ％ . (5) flotsam again forge points to in die forging ≥1 after forging recycle the punching gross of this forging or L of Qian Ga first class flotsam again die forging with obtaining ≥1 again (plant) the figuration of a kind of die forging of small forging of different figure and dimension. Flotsam again forge but utmost land increases gear forging overall material utilization factor, have more essence of life, cleaner, more the characteristic of the province. But again forge flotsam is more difficult match with the photograph such as the material brand of new forging, appearance and dimension or bulk. Gear flotsam again forge (process of 5) seeing a picture is: First preform figuration of 1 die forging is gear forging 3 with gear punching gross 2, recycle punching gross pushs mat forging till figuration of 2 flotsam die forging 6, will stop finally push mat forging the punching gross of 6 5 again strong cut or machine add for nut spacer 8. Gear flotsam again forge realized one makings the circular recycle of 3 forge and flotsam of gear punching gross, can reduce raw material to use up 12 ％ . (6) adds up to forge many times to point to with ≥2 of a preform general (kind) forging adds up to the repass after be die forging of an organic whole forge is cut, curium cut or the method of figuration of a kind of die forging that the method such as line cut cuts off depart. Many add up to forge to be able to reduce forging and forging die breed, different forging has same material brand and batch, and identical or the mechanical function of close. But forging of obtains avery kind of is forginging to be tasted with the total qualification after machine treatment when rate is not same, the final amount of forging of avery kind of is accomplished hard one to one correspondence, still may increase forging die size, increase tonnage of die forging equipment and efficiency of influence die forging. Forging of connecting rod of 396 diesel engine builds two an organic whole to combine forge figuration for connecting rod and connecting rod (6) seeing a picture, use order die forging law mixes figuration to be out of shape principle of die forging law optimizes forging die design instead, improved sex of die forging craft effectively, decreased to forging working procedure amount, reduced forging specific power consumption, ensured forging is mechanical function and quality consistency are good, the figuration when realizing save labour and province (the effect of die forging figuration on the hammer of 3t die forging with opposite blow lesser energy exceeded the result of die forging figuration on hammer of 5t die forging) .
