Abstract
Bending presses containing pistons providing up and down motion of the upper clamp, at least one engine for motion of the said pistons, and filling valves providing pre-filling during quick down and up motion of the pistons. The bending presses contain at least one pump of variable rotation and fixed displacement transmitting the motion received from the said engine to the pistons.
Claims7
The invention relates to bending presses containing pistons providing up and down motion of the upper clamp, at least one engine for motion of the said pistons, valves providing pre-filling during quick down and up motion of the pistons and it comprises at least one pump of variable rotation, fixed displacement transmitting the motion received from the said engine to the pistons.
The invention is a method relating to bending presses containing pistons providing up and down motion of the upper clamp, at least one engine for motion of the said pistons, valves providing pre-filling during quick down and up motion of the pistons wherein upon driving of the pumps by engines, the pumps rotate in descending direction and upper clamp is moved downward.
