摘要： Draw processing flat-rolled sheet metal substrate preselectively precoated on each surface with organic coating and draw lubricant into one-piece can bodies ready for assembly into sanitary can packs free of any requirement for applying organic coating or adding organic coating for repair purposes after fabrication and before such direct usage. Cupping of precoated flat-rolled sheet metal can stock using preselected tooling configurations and clearance avoids any increase in side wall metal thickness gage. Tension elongation during redraw is controlled over side wall height by clamping solely between planar clamping surfaces, tooling configurations and preselected clearances to decrease thickness gage uniformly over side wall height between flange metal open end of can body and curved transition zone at closed end. High production rate blanking and cupping is achieved with out-of-phase simultaneous movement of cupping die and punch which provides for rapid discharge cup-shaped work product, open-end-down on flange at open end of cup. Surface area of the cavity entrance zone for each die is fabricated about multiple radii forming sharp edge about which coated can stock is drawn into each die cavity. Curved surface transition zone for each punch is maintained large in relation to sheet metal substrate starting gage which facilitates change of configuration of metal from planar state into cylindrical side wall.

摘要： Method for aiding sheet metal forming tool design, for use with a computer including memory, and forming tools including a draw die, punch and binder having surfaces designed to form the sheet metal into a part, the sheet metal being represented as a mesh including a plurality of nodes. The method includes evaluating an initial binder-set associated with an initial binder surface design during a first stage of forming the sheet metal in which at least one of the plurality of sheet metal mesh nodes is forced against the binder surface, and detecting an area of unacceptable deformation on the sheet metal mesh. The method also includes identifying the at least one of the plurality nodes forced against the binder surface associated with the unacceptable sheet metal deformation and releasing the at least one of the plurality of nodes identified, so as to allow the identified nodes to move as the sheet metal assumes a relaxed state. The method also includes redesigning the initial binder surface based on the relaxed state to obtain a modified binder surface.

摘要： A method for the iterative process optimization of drawing processes, occurring in timed sequence, in drawing presses, in which the clamping force which can be set at the blank holder is reduced (in the case of fractures) or increased (in the case of folding) or maintained at the same level (in the case of acceptable parts) for a subsequent working cycle as a function of the drawn part quality of a drawn part drawn in a proceeding working cycle. In order to be able to detect the drawn part quality with respect to the criteria of fractures, acceptable or folding automatically during each working cycle and, accordingly, to be able to design the optimization process as a genuine control process which occurs automatically in a closed cycle, before the start-up of production of a specific type of a part to be drawn, a pressing stroke-dependent desired value drawing force range of the drawing force exerted on the drawn part during the drawing process is detected and the data are stored, the drawing force needing to stay within this range in order to be able to expect fracture-free and fold-free, that is to say acceptable drawn parts. During production, the pressing-stroke-dependent actual-value drawing force variation is measured and it is monitored whether this variation stays within thaws desired-value drawing force range during the entire drawing path and/or whether it has exceeded (fractures) or undershot (folds) the desired-value drawing force range. Influencing factors which are relevant to the drawing process and can be detected on the semi-finished product are also continuously detected and appropriately taken into account when setting the blank-holding force.

摘要： Draw processing flat-rolled sheet metal substrate preselectively precoated on each surface with organic coating and draw lubricant into one-piece can bodies ready for assembly into sanitary packs free of any requirement for washing, organic coating or repair of organic coating after fabrication and before such direct usage. Selective organic precoating includes embodying a blooming compound which is made available as draw lubricant responsive to heat and/or pressure of draw forming; also, surface application of a draw lubricant after curing of the organic coating. Combined lubricant on each surface is verified before start of fabricating. Draw-forming of tensile strength sheet metal is controlled over side wall height by clamping solely between planar clamping surfaces and by interruption of draw to establish a flange at the open end of cup-shaped work product. Surface area of the cavity entrance zone for each die is preselected along with curved surface transition zone on draw punch in relation to sheet metal substrate starting gage. Nesting of curvilinear clamping surfaces of the prior art is eliminated during redraw of work product. The curved transition zone of cup-shaped work product is reshaped prior to redraw.

摘要： Shipping container carrying cargoes requiring temperature control and/or ventilation require a main frame capable of housing a refrigeration unit. Hitherto, main frames have been constructed by welding the component parts together which is extremely time consuming. The present invention provides a method for producing a main frame in which a recessed portion for housing the refrigeration unit is deep drawn while a force is simultaneously applied to maintain a substantially constant thickness of the main frame.

摘要： New technology for deep drawing can bodies for use in the manufacture of two-piece cans for food and beverage products from precoated flat-rolled sheet metal can stock in which damage to can stock precoated on both surfaces with an organic coating is avoided and draw-forming of the side wall is controlled to decrease metal requirements. A draw die cavity entrance (47, 74) is selected to provide at least a major portion of its curvilinear surface having a radius of curvature of about five times nominal sheet metal thickness gage, or less, e.g. a maximum radius of curvature of .04 inch is used for the more commonly used can stock materials. During cup redraw, nesting of curvilinear clamping surfaces (21, 26) of the prior art is eliminated; the compound curvilinear juncture of a work product cup, between its endwall and side wall, is reshaped about a clamping ring compound curvilinear transition zone (72) of smaller surface area than the cup juncture, and the sheet metal is clamped solely between planar clamping surfaces (63, 71) during redraw to a smaller diameter utilizing a male punch (66) with a punch nose ( 79) having a significantly larger surface area than that of the cavity entrance zone.

摘要： In the method proposed a peripheral wall with at least one axial section of high shaping and fitting accuracy is made by forming an initial blank. This accuracy is achieved, in that before the peripheral wall is formed, sheet material which has been put into a plastic state is swaged in places round the periphery, then the swaged locations are sized, and/or in that during or after the formation of the peripheral wall, the wall is shaped by stamping in a plurality of places along its periphery, whereby the said zone providing shaping and fitting accuracy is formed from fitting areas at at least one side of the peripheral wall in the region of the swaged and/or stamped locations. An apparatus for carrying out such a method is generally in the form of a drawing machine, wherein the holder and/or the bottom die contain radial apertures, which open into the inner edge of the holder and/or into the shaping cavity of the die, and which are arranged at intervals round the periphery. The wall surfaces of the upper die and/or of the shaping cavity act as sizing surfaces to form fitting areas in swaged locations on the peripheral wall of the shaped part, the swaged locations being formed by said apertures.
