Abstract
Abstract The machine serves for a continuous swaging of elongated workpieces moving along a predetermined path and comprises a machine housing surrounding said path, a plurality of hammers which are similar to connecting rods and mounted in said housing, a plurality of eccentrics, each of which is operatively connected to one of said hammers and rotatable to impart to said hammers a reciprocating motion toward and away from said path in a direction which is radial to said path, and an oscillating motion, and a plurality of slide bearings associated with respective ones of said hammers and permitting of said reciprocating and oscillating motions of said hammers relative to said housing. Each of said slide bearings comprises a sliding member forming a bearing shell, guide means mounted in said housing and adapted to guide said sliding member in its longitudinal direction toward and away from said path, and a bearing member which is rigid with the associated hammer and has a curved bearing surface extending in and in bearing contact with said bearing shell to permit of said oscillating motion of said hammer relative to said sliding member.

A swaging machine for a continuous swaging of elongated workpieces moving along a predetermined path, which comprises a machine housing surrounding said path, a plurality of hammers, which are similar to connecting rods and mounted in said housing, a plurality of eccentrics, each of which is operatively connected to one of said hammers and rotatable to impart to said hammers a reciprocating motion toward and away from said path in a direction which is radial to said path, and an oscillating motion, and a plurality of slide bearings associated with respective ones of said hammers and permitting of said reciprocating and oscillating motions of said hammers relative to said housing, each of said slide bearings comprising a sliding member forming a bearing shell, guide means mounted in said housing and adapted to guide said sliding member in its longitudinal direction toward and away from said path, and a bearing member which is rigid with the associated hammer and has a curved bearing surface extending in and in bearing contact with said bearing shell to permit of said oscillating motion of said hammer relative to said sliding member.
Claim 2
Dependent Claim
187 words
A swaging machine for a continuous swaging of elongated workpieces moving along a predetermined path, which comprises a machine housing surrounding said path, a plurality of hammers, which are similar to connecting rods and mounted in said housing, a plurality of eccentrics, each of which is operatively connected to one of said hammers and rotatable to impart to said hammers a reciprocating motion toward and away from said path in a direction which is radial to said path, and an oscillating motion, and a plurality of slide bearings associated with respective ones of said hammers and permitting of said reciprocating and oscillating motions of said hammers relative to said housing, each of said slide bearings comprising a sliding member forming a bearing shell, guide means mounted in said housing and adapted to guide said sliding member in its longitudinal direction toward and away from said path, and a bearing member which is rigid with the associated hammer and has a curved bearing surface extending in and in bearing contact with said bearing shell to permit of said oscillating motion of said hammer relative to said sliding member.
Claim 3
Dependent Claim
31 words
A swaging machine as set forth in claim 1, in which each of said guide means comprises a bearing bushing in which said sliding member is guided in its longitudinal direction.
Claim 4
Dependent Claim
16 words
A swaging machine as set forth in claim 1, in which said curved surface is spherical.
Claim 5
Dependent Claim
55 words
A swaging machine as set forth in claim 1, which comprises a plurality of bellows seals, each of which is disposed between the sliding member of one of said bearings and the hammer associated therewith, and a plurality of annular seals, each of which is disposed between one of said sliding members and said housing.
Claim 6
Dependent Claim
109 words
A swaging machine as set forth in claim 1, in which each of said hammers constitutes a spider of an elliptic chuck, each of said eccentrics is non-rotatably connected to an eccentric shaft, which extends parallel to said path, each of said elliptic chucks comprises an integral link member, which is mounted on one of said eccentric shafts and longitudinally slidable along the same, and the link and spider of each of said elliptic chucks have meshing helical teeth, whereby upon a rotation of said eccentric shafts said eccentrics impart to said hammers said reciprocating motion and said links and meshing teeth impart to said hammers said oscillating motion.
