Abstract: 970,332. Making press tools; casting machines; casting composite articles; stamping. JEWEL ENGINEERING (LEICESTER) Ltd. April 8, 1963 [April 24, 1962], No. 15463/62. Headings B3A, B3F and B3Q. [Also in Division B5] Complementary male and female press tools for the production of articles drawn to shape from sheet material are made by casting them in situ in the actual press in which the articles are to be produced. An hydraulic press for forming radiator headers from sheet metal comprises a bath 18 containing a low melting point bismuth alloy with a jacket J to which hot or cold water may be supplied. In the lower part of the bath is a perforated partition 28 beneath which is an inflatable bag 46. The press ram 29 carries a T-beam 32 which forms the core of the male die member T and which has internal channels 34 to which hot or cold water may be supplied. Smaller rams 37 carry a blank holder 39 with an opening 40 through which the T-bar 32 can protrude, and a replaceable blank holder plate 41 which is placed in position after the press tools have been formed and has a central opening 42 which closely fits the particular press tool T. In operation an original 44 of the article to be produced and with a perforated bottom is stuck to a die face plate 43 and placed in the bath of metal made molten by passing hot water through the jacket, the metal passing through the perforations in the bottom of the original 44 to fill it, Fig. 4. The blank holder 39 is then lowered by the rams 37 and then the T-beam 32 is inserted into the melt by lowering the main ram 29. Coolant is then circulated through the T-beam to form a frozen crust C which seals the bath, and the bag 46 is inflated to hold the molten metal against the original 44 and compensate for shrinkage of the melt. Coolant also flows through the jacket J to complete solidification. The rams 29, 37 are retracted, carrying the cast press tool T and the original 44 which latter is then stripped from the tool, leaving the male and female tools T, T<SP>1</SP>, ready for use. Steel elements which it is desired to incorporate in the male tool at particular points of sharp radii &c. may be secured to the original 44 as by an adhesive, before it is immersed in the melt. After completion of a manufacturing run the tools may be melted down by running hot water through the jacket J and the T-beam 32. In a modification the top of the melt is cooled to form the crust C by flowing coolant directly over the top surface from a shallow bath mounted on the top of the surrounding flask 13. In another embodiment pressure is applied to the bottom of the melt by compressed air applied to a perforated chamber mounted on the bottom of the bath. The press may be provided with refrigerating means to cool the tools to a very low temperature. The tools may be cast of non- metallic materials and the press may be for the production of goods drawn or stretched from marginally held sheets of leather, plastic &c.
