摘要： A novel process is disclosed by which contorted or distorted sheet gauge steel and other metal scrap material, generated by stamping and other deforming metal-working operations, is flattened by rolls (50,60) for the purpose of increasing the bulk density and to provide a scrap product that can more efficiently be transported and used for remelting in steel-making and foundry furnaces. The process involves the steps of feeding contorted sheet metal scrap between a pair of moving compressive surfaces, compressing the scrap to substantial flatness, and discharging the flattened steel scrap. The novel apparatus for performing the process is also disclosed.

摘要： The disclosure relates to a variable force die spring (20) as disclosed which combines high force, short axial compression distance spring assembly (72), such as belleville springs, and low force, high axial compression distance springs (70), such as coil springs, in a telescoping casing (24,26) having an internal cavity (60). The springs are arranged within the cavity so that upon receiving a load the low force spring will compress first resulting in a large axial compression and low force resistance. The load applied to the telescoping casing (24,26) will then transition from the low force spring to the high force spring. The high force spring then compresses as the load continues to be applied. In alternative embodiments, a third intermediate spring is addred that compresses moderate distances under moderate pressure thereby increasing the overall axial compression and load capacity capabilities of the spring assembly. In any embodiment, the invention results in a spring that provides high forces and low axial compression when it is nearly fully compressed and low forces and high axial compression at all other stages of compression.
摘要翻译： 本公开涉及一种如权利要求所述的可变力模具弹簧（20），其结合了诸如贝氏弹簧的高力，短轴向压缩距离弹簧组件（72）以及低力，高轴向压缩距离弹簧（70） 弹簧，在具有内腔（60）的伸缩壳体（24,26）中。 弹簧布置在腔内，使得在接收到负载时，低力弹簧将首先压缩，导致大的轴向压缩和低的抗力。 施加到伸缩壳体（24,26）的负载将从低力弹簧转换到高力弹簧。 然后，高力弹簧随着负载继续施加而压缩。 在替代实施例中，添加第三中间弹簧，其在中等压力下压缩中等距离，从而增加弹簧组件的整体轴向压缩和负载能力能力。 在任何实施例中，本发明导致弹簧，当其几乎完全被压缩时提供高的力和低的轴向压缩，并且在所有其他压缩阶段都产生低的力和高的轴向压缩。

摘要： A fluid-pressure operated punching apparatus (10) includes an elongated substantially cylindrical punch support assembly (31) slidably disposed for reciprocatory, lengthwise sliding movement in a cylindrical opening (13) in a body (11). The punch support assembly (31) has a piston head (36) at the rearward end thereof and a piston rod (35) extending lengthwise forwardly from the piston head (34). A punch retainer (33) is mounted on the forward end of the piston rod (35) and carries a punch (78). Annular sealing means (50) are provided on the piston head for sealingly engaging the internal surface defining the cylindrical opening (13) of the elongated body. A fluid pressure supply port (94) is formed in the body (11) for supplying pressure fluid to move the punch support (31) assembly toward the forward end of the body (11).
