Abstract
A swing beam press in which the beam is supported on a column which stands up from the machine frame. The column contains a piston-cylinder unit for raising and lowering the beam. The cylinder is formed in the column and a piston rod of the piston projects upwardly out of the column and supports the beam. The beam has a downwards projection which embraces the column to guide the movement of the beam. This construction reduces the friction involved in beam movement and reduces costs.
Claims4
A swing beam press machine comprising a column for the swing beam, which column projects from a frame of the machine and contains therewithin a piston and cylinder unit for effecting the stroke movement of the swing beam which extends away from the column, wherein:
- the column is fixedly mounted on the machine frame and forms the cylinder for the piston and cylinder unit having a piston rod which extends through an upper abutment of the cylinder and projects out of the upper end of the column and connects to the swing beam;
- the connection between the piston rod and the swing beam consists of a sleeve which slides on the outer wall of the column, and which has a cover closing off the sleeve, which cover is secured to the piston rod.
