Abstract

An improved arrangement is provided for relatively reciprocating the ram and blank holder components of a horizontal can blank forming machine. The machine includes a reciprocable slide carrying the ram, and a reciprocable blank holder frame on which the blank holder is mounted. The slide and blank holder frame are driven by a common crankshaft through corresponding crank arms angularly related circumferentially of the crankshaft axis to impart the desired motion characteristics to the slide and blank holder frame upon rotation of the crankshaft. The blank holder frame includes a vertical plate member defining the driven end of the blank holder frame, and horizontal rods interconnect the vertical plate with a frame plate at the opposite end of the blank holder frame and on which the blank holder is mounted. The axes of the crankshaft, blank holder, blank holder frame rods and ram are coplanar with one another and with the axes between the crank arms and the blank holder frame and slide.

Dependent claims

In a cup-shaped article forming machine including a main frame, a tubular blank holder having an axis, blank holder frame means carrying said blank holder and supported by said main frame for reciprocating movement along a linear path parallel to said axis and between first and second locations, a die ring supported by said main frame in axial alignment with said blank holder, said blank holder receiving a cup-shaped blank during movement of said frame means in the direction from said first location toward said second location and positioning said blank relative to said die ring when said frame means is in said second location, a punch member coaxial with said blank holder, a slide supporting said punch member for reciprocating movement relative to said main frame and including movement in said direction and through said blank holder to engage and carry said blank through said die ring, and drive means to reciprocate said blank holder frame means and said slide, the improvement comprising:

said drive means including crank means supported by said main frame for rotation about a crank axis transverse to said linear path, and connecting rod means having opposite ends, one of said opposite ends being pivotally connected directly to said crank means at an axiis parallel to and spaced from said crank axis, and the other of said opposite ends being pivotally connected directly to said blank holder frame means, whereby rotation of said crank means reciprocates said blank holder frame means.

In a cup-shaped article forming machine including a main frame, a hollow cylindrical blank holder having an axis, blank holder frame means carrying said blank holder and supported by said main frame for reciprocating movement along a linear path parallel to said axis and between first and second locations, a die ring supported by said main frame in axial alignment with said blank holder, said blank holder receiving a cup-shaped blank during movement of said frame means in the direction from said first location toward said second location and positioning said blank relative to said die ring when said frame means is in said second location, a punch member coaxial with said blank holder, a slide supporting said punch member for reciprocating movement relative to said main frame and including movement in said direction and through said blank holder to engage and carry said blank through said die ring, and drive means to reciprocate said blank holder frame means and said slide, the improvement comprising:

said blank holder frame means including end members spaced apart in the direction of said blank holder axis and interconnected by side members spaced apart in the direction laterally of said axis, said blank holder being mounted on one of said end members, the other of said end members having an opening therethrough, said blank holder frame means and said main frame including interengaging guide means guiding said reciprocating movement of said blank holder frame means, said slide being between said end members of said blank holder frame means, and said drive means including crank means supported by said main frame for rotation about a crank axis transverse to said blank holder axis, first connecting rod means extending through said opening in said other end member and having opposite ends pivotally interconnected one with said crank means at an axis parallel to and spaced from said crank axis and the other with said slide, and second connecting rod means having opposite ends pivotally interconnected one with said crank means and the other with said blank holder frame means.
