Definitions
- the invention relates to a mold jaw of a rotary swaging tool for forming a plastically deformable, preferably metallic, workpiece.
- the invention also relates to a rotary kneading tool with mold jaws of the aforementioned type.
- rotary swaging is a pressure forming process, specifically free forming.
- a rotary kneading tool has mold jaws that are on opposite sides of a tool to be formed
- the previously known mold jaws in their entirety have high-quality material properties that are required in particular for a functionally reliable introduction of the forming forces to be applied into the workpiece to be machined.
- the previously known form jaws are made of hard metal. Due to their consistently high-quality material properties, the previously known mold blocks are relatively expensive. In addition, the material properties of the mold blocks are primarily tailored to their forming function. An appropriately dimensioned hardness of the previously known mold jaws is disadvantageous in that it causes relatively strong wear during relative movements of the mold jaws and components in contact therewith, particularly on wedges for the radial adjustment of the mold jaws.
- the shaping surface of the mold block is provided on a structurally separate mold body from the backing base body of the mold block.
- the jaw base body and the mold body of the mold jaw can be configured independently of one another.
- the shaped body is fitted into a receptacle provided for this purpose in the basic jaw body and is thereby defined relative to the basic jaw body and preferably positioned without play.
- the fitting of the shaped body into the jaw base body can cause the shaped body to be supported on the jaw base body without play on all sides or only in individual directions.
- At least one securing element is used to fix the shaped body to the jaw base body.
- Claim 4 relates to an inventively preferred arrangement of the securing element used to fix the shaped body to the jaw base body. merits Due to the arrangement in a gap between a wall of the holder of the jaw base body on the one hand and the mold body on the other hand, the securing element on the workpiece side of the mold jaw does not form any interfering contours that could impede workpiece processing. In addition to the securing element, appropriate fitting of the shaped body into the jaw base body can ensure play-free mounting of the shaped body on the jaw base body.
- the securing element or elements bring about a play-free mounting of the shaped body in its longitudinal direction and perpendicular to the base of the receptacle and that the fitting of the shaped body into the jaw base body is provided for play-free mounting of the shaped body in its transverse direction parallel to the base of the receptacle .
- the shaped body of the shaped jaw according to the invention can be permanently connected to the jaw base body.
- a detachable connection of the shaped body to the jaw base body is preferred (claim 5). Because of this feature of the invention, there is, for example, the possibility of exchanging a worn molded body for a new molded body with little effort.
- shaped bodies with different geometries of the shaping surface can be easily attached to one and the same basic jaw body.
- a fastening screw which passes through the securing element and is screwed into the base of the receptacle of the basic jaw body provided for the shaped body is used for the detachable connection of the shaped body to the jaw base body.
- the securing element is fixed in a position by means of the fastening screw, in which the securing element lies laterally opposite the shaped body.

- the fastening screw in cooperation with the securing element, prevents the shaped body from being lifted off the bottom of the receptacle of the jaw base body.
- the securing element is moved relative to the shaped body along the thread axis by screwing the fastening screw into the threaded opening of the jaw base body with a feed movement towards the bottom of the receptacle of the jaw base body. Due to the infeed movement of the securing element and the wedge-shaped design of the shaped body and/or the securing element, the shaped body is placed without play by means of the securing element on the side remote from the securing element against the wall of the receptacle of the jaw base body, preferably prestressed against the wall of the receptacle of the jaw base body.
- the shaped body engages behind an edge of an opening of the receptacle of the jaw base body parallel to the base of the receptacle on the side of the shaped body remote from the securing element. Because of this feature of the invention, the shaped body mounted on the jaw base body is also positively secured on its side remote from the securing element against lifting off the base of the receptacle of the jaw base body.
- the end of the shaped body that engages behind the edge of the opening of the receptacle of the jaw base body has a boundary surface which runs inclined towards the base of the receptacle and which is opposite an inclined surface of the jaw base body inclined in the same direction. The shaped body can be pre-stressed against the jaw base body on the inclined surfaces lying opposite one another.
