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 0.04 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 end wall 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 a method of drawing and wall ironing a can body, a blank (1) is cut from a laminate of aluminium or alloy and a polyester film. The blank is lubricated and drawn to a cup (7) having a side wall (8), which is then wall ironed. A terminal margin (14) of the side wall (13) of the wall ironed can is heated to a temperature above 100.degree. C. but below the crystalline melting point of the polyester film in order to prevent delamination of the polyester film from the side wall of the can during subsequent washing of the can. A benefit of the process is that the heating of the side wall margin (14) does not soften the aluminium or aluminium alloy body.

摘要： The invention includes apparatus and method for lubricating and cooling a workpiece, dies or ironing rings, and punch at the interface between the workpiece and such dies or ironing rings and punch in forming a workpiece into a hollow closed end cylindrical article.A lubricant liquid phase is injected into a coolant liquid phase to form a "dispersion" prior to application to the metal-tool interface. Providing the lubricant as a dispersion in the coolant liquid phase rather than as an emulsion provides several advantages. The quantity of lubricant and the time of lubricant injection can be varied to control lubricity and, thus, friction. The invention makes it possible to achieve differential friction in the ironing process by having higher lubricity on the ironing die (low friction) and lower lubricity on the punch surface (high friction). Lubricities and cooling are controllable for the specific metal forming process employed to produce closed end hollow body containers. After applicaiton, the lubricant and coolant are separated, the lubricant filtered to remove debris, stored, and then reinjected to provide lubrication for the process.
摘要翻译： 本发明包括用于润滑和冷却工件，模具或熨烫环的装置和方法，以及在工件与这种模具或熨烫环之间的界面处冲压和冲压成型工件到中空的封闭端圆柱形制品中的装置和方法。 将润滑剂液相注入冷却剂液相以在施加到金属 - 工具界面之前形成“分散体”。 将润滑剂作为分散体提供在冷却剂液相而不是乳液中提供了几个优点。 可以改变润滑剂的量和润滑剂注入的时间以控制润滑性，从而控制摩擦。 本发明通过在熨烫模具上具有较高的润滑性（低摩擦）和较低的冲压表面上的润滑性（高摩擦），可以实现熨烫过程中的差动摩擦。 对于用于生产封闭端中空体容器的特定金属成型工艺，可以控制润滑和冷却。 在应用之后，润滑剂和冷却剂被分离，润滑剂被过滤以除去碎屑，储存，然后再注入以提供该过程的润滑。

摘要： An individually variable multi-stage drawing apparatus has a succession of drawing stations in a multi-level configuration, each station other than the first being vertically offset from and at a level lower than that of a preceding station. Each station includes a circular die through which a workpiece is forced by a cylindrical plunger. Each plunger is operated by its own individual hydraulic ram. In this way, plunger movement commences at a pressure and continues at a rate governed by the metallic flow requirements of the workpiece at each successive drawing stage.The invention further comprises transfer devices for shifting the workpieces from one drawing stage to the next. These transfer devices grip, carry and release the workpieces without subjecting them to potentially damaging frictional contact.

摘要： A method and apparatus for measuring the sidewall tension in a workpiece being drawn through a draw die and/or ironing die. A punch is provided which is adapted to measure and continuously monitor the axial load on the punch nose and the total axial load on the punch, the distribution of such loads around the periphery of the punch, and bending of the punch near the base and nose due to lateral and nonuniform forces acting on the punch as the workpiece is forced through a die or dies. Determination of the forces, their distribution, and punch bending enables accurately determining the tensile stress at any portion of the sidewall.
