progressive die for backrest board level ABSTRACT The topic of this design is the design of progressive die for backrest board level reflect the contents and requirements design of punching direction of bending parts the design of a certain significance Through the design of the die parts to further strengthen the basic knowledge of the designers of the progressive die design which paves the way for a more profound experience and lessons for the design of more complex progressive die III The use of design drawing based blanking bending forming process and die design is firstly analyzes the requirements of cost and performance parts ready for the selection of process scheme for the types of mold then analyzed the shape and size of parts easy selection of die finally analyses the parts feature selection design and mold design parameter die of This part is the design of progressive die for the backrest plate part level the blanking and punching bending and other design in a die the die has the advantages of simple operation high production efficiency reliable performance This design through process integrated parts of the economy including the comprehensive analysis of parts stamping process analysis analysis and determine the stamping process scheme compared schemes from scheme scheme two scheme three scheme four the fifth scheme finally determined the scheme Then the process calculation including calculation of blank size layout and the conference board cutting method steps to determine the distance accuracy blanking force calculation falling process punching material process bending process and the mould structure form selection determine and check discharge device positioning device die and punch and die cutting edge size Finally mold design mold design of the working parts and so on a series of design the design of all one one are described Only with such a complete set of design The passage expounds on the structure designing project and work process of the progressive die and uses some working procedures such as punching flangin g blanking and so on to process through the technologic analysis of the system Through calc ulating the process to determine the center of the die s pressure and select the model of the pr esses Blanking die is fixed by connecting the die holder with the die set The die adoptsthe w ay of lower ejection and elasticity discharge devices Its structure is relatively simple the perf ormance is reliable and the work is steady It has improved the producing efficiency and reduc ed the intensity of labor and cost of production Bending die is a kind of cold stamping die is refers to through certain procedu rewill die blank punching forming Classification according to the process properties of sta IV mping bending die is makes the material blanking die plastic deformation This thesis also includes the stamping process analysis and process calculation of the parts determining t he reasonable stamping process scheme design two sets of mould pressing procedure th e correct selection of standard parts and other parts the structure of the stamping proce ss analysis of the selectedpressure machine Drawing die assembly drawing and 2D The p rogressive diedesign in order to consolidateand deepen the knowledge This paper designs a bent and punched multi position progressive die According to the measurement material and requirements of batch p roduction of the indispensable components manufacturability of the components is carefully analysed in the first place to determine the structure of the dies and how to punch them After wards process design method was employed to decide layout and calculate stamping pressure and pressure center with which pressing machines can be chosen At the same time the meas urements of both cavity and terrace die and their tolerance were calculated In the end proper components were designed using Pro E In the de sign of die structure the cavity and terrace die locating element and discharge unit were speci ally designed As to some components standard components were adopted Meantime worki ng process were analysed in details KEYWORDS Progressive
