摘要： The work tools of a stamping press, together with slides and ancillary parts, are built as a separate unit that can be easily removed for maintenance or programmer changes. Unskilled labour can be used for this operation, and changing time is greatly reduces so that productivity is increased. The unit is held in the press proper by means of a single pressure nut.

摘要： With the bolt in the upper part of the corner drilling and a sleeve in the lower part, they are secured to each other through their threads at the mould dividing line. As the threads extend over a greater part of their length, a wide variety of half mould thicknesses and core depths can be used with the same clamping bolt system.

摘要： 1283717 Die sets PORTER PRECISION PRODUCTS CO 5 Aug 1969 [11 Sept 1968] 39217/69 Heading B3W The upper and lower shoes 13 and 15 of a die set are located by a plurality of guide post assemblies 10, each of which comprises a tubular sleeve 25 attached to one of the shoes and slidable within a bush 26 attached to, or formed as a bore in, the other shoe, spring means, such as a solid cylindrical polyurethane member 33, within the sleeve tending to urge the shoes apart by bearing at one end on a member rigid with the shoe to which the sleeve is attached and at the other on the head 36 of a pin 27 which is fixed relatively to the bush 26. As shown, Fig. 2, the spring 33 bears on a back-up plate 12 and the lower die shoe 15 is clamped at 42 to a bolster plate 31 on which the pin 27 bears. In an alternative form of guidepost assembly, Fig. 7 (not shown), the sleeve is secured to the upper die shoe by means of a bush (51) and is axially aligned within the bush (55) mounted on the lower die shoe by means of roller bearings (60) in a inner bush (58). A punch 14 is mounted on shoe 13, which is not attached to actuating ram 47, and a die 16 is mounted on shoe 15. A stripper plate 17 rigidly secured to the die is recessed at 18 to receive a workpiece 20. During punching the springs 33 are compressed to the shape shown in Fig. 2 and, in regaining their shape as shown in Fig. 4 as the ram 47 is raised, lift the upper die shoe 13 and back-up plate 12 and cause the workpiece 20 to be stripped from punch 14 by plate 17. To provide additional stripping force, each sleeve 25 may be surrounded by a poly. urethane bush (not shown) which is compressed during punching between the bush 26 and the shoe 13.

摘要： Gauges for the erection, assembly and checking of drawing, stamping and press tools are made from an epoxy resin laminate. The master pattern is set into a frame and covered with a parting medium. fter this a gel coat of liquid resin and hardener with a silica filler is applied. After setting, a fibre glass reinforced layer is applied. On this is applied a final layer about 10 mm thick of a resin mixture comprising a filler, glass fibre pieces, polystyrene granules and silica powder. When this is set, the finished gauge is mounted into its holder or frame employing a paste of the same composn. The resin employed is an epoxy resin to which a hardener has to be added. The method is inexpensive and accurate and well suited for the prepn. of large gauges which must not be too heavy.

摘要： Die set for the forming of bowl shaped objects with a rolled rim from thin metal foil, partic. aluminium foil in one single pressing operation. The set consists of an upper female and lower male part with locating surfaces for the foil or rim of stamping, there being an additional groove ring which is separately loaded and has a separate locating face for the rim during the end of the pressing cycle, where it reduces the locating pressure by virture of its independent spring loading preventing tearing of the workpiece, the rolled rim being formed during the return stroke.
