1、Complicated Curved The Stalk Pressure Machine Mold Duan Compound Forge CraftSummaryAim at the technique characteristics of many problems and that type of Duan piece oneselfs of the light sedan complicated and curved stalk Duan piece existing production craft, this text puts forward Gun Duan-rub the
2、pressure machine mold Duan compound craft project, introduce concerning the semi-finished product of Gun Duan, bent semi-finished product, curve back to play, curve a work preface of reasonable arrangement etc. technological design important point and the reasonable structure and design of the moldi
3、ng tool.Be investigated enunciation by actual production:This craft project forerunner reasonable, the production line stabilize credibility, the economic efficiency shows Zhao.The technological design method in this text as to its it complicated curved stalk Duan the piece contain universal referen
4、ce meaningKeyword:Complicated curved stalk Duan piece;Compound forging craft;Light sedanA, forewordComplicated and curved stalk Duan piece of the best take shape a method have been the problem that forges profession to concentrate on a research, a little bit ex- year of our country light sedan produ
5、ction amount not big, dont form scale management, the past light sedan is complicated curved stalk Duan the production of the piece mainly with mold Duan of traditional hammer the craft carry on small batch quantity production, the factory house for having even adopts free Duan-foetus mold Duan craf
6、t, needing several fire times then can Duan become.In recent years, our country the light sedan production quickly develops and produces a batch quantity more and more greatly, the whole mechanism builds level more and more high, to complicated curved stalk Duan piece and speech, not only the shape
7、is complicated, and Duan piece size accuracy, the request of surface quality etc. also more strict, so investigate a light sedan complicated curved stalk Duan the reasonable forging method of the piece, seem to be is importance.Produce an actual need according to a the vapor light sedan, in experime
8、nting a research of foundation, we adopted the Gun Duan system Pi-rub the pressure machine mold Duan compound craft to act for mold Duan of traditional hammer, the gave birth to light car turns to the left toward the stanza arm, the sedan of Ao Di is left and right under control arm etc. five kinds
9、of complicated curved stalk Duan piece, its Duan piece the technique level come to a light car and the sedan of Ao Di original diagram paper to design a request, various index signs with economic techniques all come to an an expectation target.Two, craft analysis and project assuranceLight sedan com
10、plicated curved stalk Duan piece, its characteristics is a stalk line to present a space curve form and much cut noodles to differ and fall bad to the flection big, shape complicated, the forging takes shape to process a difficulty with molding tool bigger.With turn to the left toward the stanza arm
11、(figure 1) is example, press mold Duan of traditional hammer craft, generally want to adopt to stir long-roll to press-flection-forging etc. the work tread.Its outstanding weakness is that the Duan piece accuracy is worse, while working vibrates noise greatly, material depletion and can consume grea
12、tly, labor condition bad.If the adoption more advanced hot mold Duan pressure machine takes shape a method, although the worker labors a condition well, rate of production and Duan piece size accuracy is higher, also easy to realization mechanization and automation, the its outstanding weakness is m
13、anufacturing cost Gao, inconvenience in pull out long, roll and press the etc. system Pi work and tread, need and go together with the other assistance equipments system Pi.Aim at many problems of the existing forging craft and the technique characteristics of the complicated curved stalk Duan piece
14、 oneself, we made sure Gun Duan-rub the pressure machine mold Duan compound forging craft of project, its craft process is:Next anticipate medium repeatedly respond heating the Gun Duan system Pi flection forging slice a side correct Duan piece quality examination.In this craft project adoption repe
15、atedly responding heat not only raised Duan piece surface quality, stabilized craft process, also can raise rate of production, the improvement labors environment.Several time Gun Duan system Pi, can availably solve complicated and curved stalk Duan piece piece noodles bad great problem, make to mak
16、e Pi shape to approach more in this launches behind of straight line shape and size, reduce a Duan piece to fly a side, save original material.In order to rubbing, the pressure machine tool has mold Duan the hammer and Duan presses machine of the dual work characteristic is rubbing pressure to carry on flection to take shape, prepare Duan on board, eventually Duan and correct to take shape, be advantageous to stable craft process, promise Duan piece quality, also have
