IPC: B21B13/22
Filed: 1969-02-20
Abstract: 1,252,482. Swaging. SOC. FIVES LILLECAIL. 20 Feb., 1969 [26 Feb., 1968; 12 July, 1968], No. 9192/69. Heading B3H. A metal working machine includes at least one pair of shoes 28 which engage a workpiece 44 and are reciprocated along inclined support blocks 14 to progressively reduce the workpiece and feed it forwards.  In one form, Fig. 1, two pairs of opposed shoes are used, the shoes being positioned within an annular housing 10. Each shoe is carried by a runner 22 which is reciprocated by an hydraulically operated arm 30. The runner bears on a block 14 which in turn is supported by a wedge 16. The wedges are movable in synchronism by screws 40, and control the die aperture formed by the shoes. After each forward movement of the jaws, the wedges are operated to move the shoes away from the workpiece during a return movement. In an alternative form, Fig. 9, the shoes are reciprocated by means of an eccentric drive. From the annular frame 110A of the machine a sub-frame 120A is suspended by arm 150, the arms being reciprocated by eccentrics 134A. Each runner 116A is coupled to the sub-frame by links 122A.  The working surfaces of the shoes, and the surfaces of the blocks 14 may be plane instead of radiused. A sizing die or rolls may be provided at the output of the machine to make the cross-section of a workpiece more uniform. The shoes may define a square, a circular, or a generally flat die aperture. If the working face of one shoe co-operates with a recess in an adjacent shoe, as in Fig. 2, the shoes may be arranged to move laterally during reciprocation, to keep the adjacent surfaces in contact. This can be effected by the use of inclined keys 21 between the blocks 14 and wedges 16. The co-operating faces of the blocks and wedges may have a low-friction coating and rollers may be provided between the runners and blocks. The jaws may have polished forward portions, and rougher rearward portions, to facilitate gripping of the workpiece. A lubricant may be injected through orifices provided in the faces of the shoes. Gripping rollers may be provided upstream of the shoes, to prevent backward movement of the workpiece. The machine may be arranged in a disposition other than the vertical one shown.

A method of simultaneously finishing a plurality of integral multifocal lens blanks B each having, on one side, an optically finished near-vision field 12 and an unfinished raised portion on which a far-vision field is to be produced, the finished field and raised portion being separated by a straight stop 24, comprises attaching the blanks to a wheel holder 68 in at least one row extending about the axis 70 of the holder with the finished surface of the nearvision field spaced from the axis the distance of the radius of curvature of the far-vision field to be produced on the unfinished portion less an amount equal to the minimum step height that will exist between the far-and near-vision fields, each blank being oriented so as to position the centre of curvature of its near-vision field and the centre of curvature of its desired far-vision field on the optical axis of the blank, which optical axis lies in the plane of the step on the blank, rotating the holder about its axis with the unfinished portions engaging an abrading means to produce the far-vision fields, and optically polishing the far-vision fields thus produced. Prior to the finishing of the far-vision fields, the near-vision fields are produced by mounting a plurality of blanks on a holder which is rotated about its axis while spherically curved nearvision fields are ground and polished to a depth greater than that of the minimum step height desired between the adjacent fields. The lens blanks to be ground may be trifocal or, as described, bifocal and may be mounted in a single or double row on the holder. As described, a double row is mounted on the holder, 68, Fig. 7, and each pair of blanks comprising one from each row are mounted on an adaptor 32, the blanks being initially positioned on the adaptor by a blocking unit 30, Fig. 6. The unit 30 is formed with a recess into which extend supporting pins 42 arranged in groups to engage the finished near-vision fields 12 and stop pins 40, the blanks being held in position on the pins by vacuum cups 52. The adaptor 32 has a datum rim 66 and is positioned at a predetermined distance x from the centre of the radius of curvature to be formed on the far-vision field with the rim engaging a magnetic chuck 58. The blanks are then secured to the adaptor by a blocking medium 72, such as low melting point alloy, pitch or other adhesive. Upon release of the vacuum and raising of a spindle 56 carrying the magnetic chuck, the adaptor is positioned by a magnetic chuck 74 on the rotary work-holder. A plurality of adaptors are mounted on the holder which is then rotated for the adjacent rows of far-vision fields to be ground and polished.
