摘要： A drawing apparatus includes blank holder and an opposing die for holding a blank therebetween, and a punch for drawing the blank. The blank holder and the opposing die include respective blank holding surfaces in which beads, having at least a portion that varies in distance from a drawing profile, are formed. In a drawing method conducted using the apparatus, a blank holder is lowered to hold the blank between the blank holder and the opposing die, and then the blank holder is further lowered so that the held blank is drawn by the punch.

摘要： A diagnostic method of diagnosing a press for the presence of any abnormality that deteriorates a quality of a product manufactured by the press, wherein physical value (Fs, Fsi, Ff, Ffi, Fp, Fpi, Xsi, Xei, Xy, Xz, Vx, Gx, Gy, Gz, Temp A, Temp B, Va0, Vf0, Vd0, V, Aa, Ag, Az, Afi, Ps, Pmai, Psa, Paa, Pyai, Peai, Pzai) such as a load generated at a selected portion of the press during operation of the press is detected, and the press is diagnosed for any abnormality, on the basis of the detected physical value, and according to a predetermined reference. For example, the diagnosis is effected based on: a waveform of a load detected in relation to a physical value which changes during a pressing cycle; a distribution of local values of the load detected local portions of the press; a correlation between the load and the physical value; a pattern of variation of the load as the number of pressing cycles; a displacement amount, velocity or acceleration, or a temperature of a selected component of the press; or a capacity of a fluid used for a cylinder which produces a load or force.

摘要： A thickness-reduced deep-draw-formed can obtained by using, as the substrate, a cold-rolled steel plate having a carbon content in the steel of 0.02 to 0.15% by weight, a manganese content in the steel of 0.2 to 1.0% by weight, a mean diameter of crystal grain of smaller than 6.0 .mu.m, a tensile strength over a range of from 35 to 55 kg/mm.sup.2, and a thickness of 0.17 to 0.30 mm in a step of subjecting an organic resin-coated structure of the surface-treated steel plate to the thickness-reducing deep-draw forming. This makes it possible to suppress the generation and accumulation of heat in the organic resin-coated steel plate to a level lower than the conventional levels. Therefore, the organic resin coating is prevented from being peeled off or damaged and, as a result, the corrosion resistance can be markedly improved. Moreover, wrinkles can be effectively prevented from developing at the time of reducing the thickness, and the forming can be continuously carried out at a high speed without being substantially affected by the generation or accumulation of heat. It is further possible to easily carry out the post treatments such as necking, flanging and multi-beading after the forming. The thickness-reduced deep-draw-formed can of the invention is effective particularly for preserving various kinds of juices, coffee, oolong tea and any other beverages after it is hermetically sealed, retort-sterilized and reduced for its internal pressure.
摘要翻译：使用钢中碳含量为0.02〜0.15重量％，钢中的锰含量为0.2〜1.0％的冷轧钢板作为基材，可以得到厚度减薄的深拉成形物，，在有机树脂被覆结构体的工序中，平均粒径小于6.0μm，拉伸强度为35〜55kg / mm 2，厚度为0.17〜0.30mm 的表面处理钢板进行厚度减薄深拉成形。这使得可以将有机树脂涂覆钢板中的热的产生和积聚抑制到低于常规水平的水平。因此，防止有机树脂涂层被剥离或损坏，结果可以显着提高耐腐蚀性。此外，在减小厚度的同时可以有效地防止褶皱的发展，并且可以高速连续地进行成形，而不会受到热的产生或积累的显着影响。还可以容易地进行后处理，例如成型后的颈缩，翻边和多重着色。本发明的厚度减薄的深拉制罐尤其适用于在气密密封，蒸煮灭菌和内压降低后保存各种果汁，咖啡，乌龙茶和任何其他饮料。

摘要： A drawing apparatus pressure pins acting upon the metal sheet holder in the bottom part of the tool are selected, has additional pressure cylinders fastened in the pressure cheek between the actual drawing apparatus acting upon a pressure cheek and the pressure pins. These additional pressure cylinders are individually controllable via valves from a pressure pipe. As a result, a precise influence is made on the drawing conditions of various sheet metal parts and their ejector movement from the bottom part of the tool.

摘要： The drawing tool comprises a hydraulic element for deriving from the movement of the blank holder a simultaneous, oppositely directed movement of the drawing punch. The hydraulic element comprises a centrally disposed working piston, an annular piston, which surrounds that working piston, and a cylinder, which surrounds the annular piston. The working piston and the annular piston are adapted to be supplied with pressure fluid from first and second cylinder chambers which are hydraulically separated from each other and which are adapted to communicate with each other under the control of at least two alternative flow paths, which differ in hydraulic design so that they cause pressure changes on different pressure levels to be effected in the second cylinder chamber. A pressure detector detects the pressure of the fluid in the cylinder chambers and enables an alternative flow path in response to a rise of the pressure above a predetermined limit. As a result, a low-cost, compact tool has been provided, which can be used to make even parts which can be drawn only with great difficulty owing to their desired final shape and/or the material from which they are made.

摘要： A process of manufacturing a sheet metal product including an opening surrounded at least partially by a drawn area, the process comprising steps of providing a pair of drawing dies, one having a drawing punch and the other having a drawing cavity adapted for cooperation with the drawing punch, putting a blank of sheet metal between the drawing dies, advancing one of the dies toward the other so that the blank is drawn by the punch and the cavity. The process includes a step of forming a slit in the blank by tearing the blank at an area which corresponds to the opening and which is adjacent to an area where the blank is stretched during the drawing step.

摘要： A method of drape drawing a shadow mask from a foraminous, or apertured, metal sheet that has a greater tensile in one direction than another and has edges extending in the one direction. During the drape procedure, the edges of the sheet that extend substantially in the direction in which the sheet has the greater tensile strength are allowed to slip relative to the draw ring and the pressure. As a result of this, the sheet is prevented from tearing.
