Title:
RE-POSITIONING DEVICE IN PUNCH PRESS
Document Type and Number:
Japanese Patent JP3939395
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To individually regulate the lowering speed of front and rear re- positioning floating cylinders and to lower them at the same speed.
SOLUTION: Work holders 43, 45 are installed on the lower ends of piston rods attached on a front and a rear re-positioning cylinders 35, 37 installed on an upper frame 3U of a punch press, re-positioning bases 55, 57 are installed on the upper ends of piston rods attached on the front and rear re-positioning floating cylinders 47, 49 installed on a lower frame 3D of the punch press, a work W is held with each work holder 45, 47 and each re-positioning base 55, 57 and holding of the work W is changed. Then, each speed controller 73, 75 is installed respectively on each circuit to lower each re-positioning base 55, 57.
