MULTIOPERATION PLANT FOR DIE FORMING AND ASSEMBLY Russian patent published in 1998 - IPC

FIELD: metal working. SUBSTANCE: plant has die set including base plate, vertical guide, columns immovably installed on base plate, cylinder horizontal plate immovably installed on upper parts of guide columns, movable plate installed for sliding on guide columns, cylinder vertically installed on cylinder plate, and having piston rod connected with movable plate, device for gripping and laying of blanks in their horizontal motion one after another and having sliders located for their horizontal motion and provided with clamping members and means for vertical motion. Upper die is secured to movable plate and lower die, to base plate. Device for gripping and laying of blanks is made in the form of manipulator mounted for forward motion of blanks of the first group, and direction of the first blank of this group to lower die. Plant has means for supply of blanks of the second group one after another to manipulator and coupling of the fed blank with the first one. Manipulator has pair of guide bars located in opposite position on bars for sliders sliding over them, coupling member connecting sliders, reciprocating cylinder for motion of sliders and a row of clamping actuating mechanisms located on sliders. Each clamping actuating mechanism has opposite clamping cylinders and clamping pins for clamping and fixation of the first blank. Operation of each pin is controlled by piston rod of respective cylinder. Plant has manipulator lifting mechanism having lifting cylinders located on base plate. Piston rod of each lifting cylinder is connected with respective guide bar for its lifting. EFFECT: higher efficiency. 3 cl, 15 dwg
