Tool for use in a swaging machine

Claim 2

A tool for use in a swaging machine which comprises four hammers, which are spaced 90* apart about an axis along which a workpiece is movable and which hammers extend radially to said axis and are intended to carry at their free ends respective ones of said tools, said tool comprising a block having the general shape of a quadrangular prism which has four longitudinal side faces, said block having a central web, which forms a narrow section of one of said longitudinal side faces and extends from one end of said block approximately over one half of the length thereof, said one longitudinal side face having a working face section which is wider than said narrow section and extends from the latter to the opposite end of said block and slopes symmetrically to the two longitudinal side faces which are adjacent to said one longitudinal side face, and said web having two side faces, each of which has in a view on said one longitudinal side face a contour which corresponds to one-half of the contour of said working face section in a view on said other end of said block.

Claim 3

A tool as set forth in claim 1, in which said working face section comprises a planar central portion, which is parallel to the longitudinal side face which is opposite to said one longitudinal side face, two curved transitional portions which tangentially adjoin said central portion, and two sloping planar end portions respectively extending toward said two longitudinal side faces.

Claim 4

In a swaging machine which comprises four hammers, which are spaced 90* apart about an axis along which a work-piece is movable, and which hammers extend radially to said axis, the provision of four tools, each of which is carried by one of said hammers at one end of the latter and comprises a block having the general shape of a quadrangular prism which has four longitudinal side faces, said block having a central web, which forms a narrow section of one of said longitudinal side faces and extends from one end of said block approximately over one-half of the length thereof, said one longitudinal side face having a working face section which is wider than said narrow section and extends from the latter to the opposite end of said block and slopes symmetrically to the two longitudinal side faces which are adjacent to said one longitudinal side face, said web having two side faces, each of which has in a view on said one longitudinal side face a contour which corresponds to one-half of the contour of said working face section in a view on said other end of said block, each of said tools being secured to one of said hammers at the longitudinal side face of said tool which is opposite to said one longitudinal side face so that said axis extends in the longitudinal direction of each of said blocks and transversely to said two adjoining side faces of each of said blocks, said four tools being generally aligned transversely to said axis, and said narrow sections of mutually adjacent blocks extending in mutually opposite directions from said working face sections of the respective blocks.

Claim 5

In a swaging machine which comprises four hammers, which are spaced 90* apart about an axis along which a work-piece is movable, and which hammers extend radially to said axis, the provision of four tools, each of which is carried by one of said hammers at one end of the latter and comprises a block having the general shape of a quadrangular prism which has four longitudinal side faces, said block having a central web, which forms a narrow section of one of said longitudinal side faces and extends from one end of said block approximately over one-half of the length thereof, said one longitudinal side face having a working face section which is wider than said narrow section and extends from the latter to the opposite end of said block and slopes symmetrically to the two longitudinal side faces which are adjacent to said one longitudinal side face, said web having two side faces, each of which has in a view on said one longitudinal side face a contour which corresponds to one-half of the contour of said working face section in a view on said other end of said block, each of said tools being secured to one of said hammers at the longitudinal side face of said tool which is opposite to said one longitudinal side face so that said axis extends in the longitudinal direction of each of said blocks and transversely to said two adjoining side faces of each of said blocks, said four tools being generally aligned transversely to said axis, and said narrow sections of mutually adjacent blocks extending in mutually opposite directions from said working face sections of the respective blocks.

Claim 6

In a swaging machine as set forth in claim 3, in which space adjacent said webs permits adjustment of said tools to different depths of penetration.
