摘要： A press system for knocking out a work from a lower die attached to a press machine has a cam 22 mounted on a bed of the press machine; a servo motor 21 which drives the cam to be rotated with the same cycle time as that of a drive mechanism of a slide of the press machine; a knockout pin 23 moved with reciprocal linear motion by the rotation of the cam; a detector 25 configured to detect a present angle information 24 of the cam, a memory storing a target angle information of the cam, and a controller 28 configured to control the servo motor in accordance with the present angle information and the target angle information. The controller is further configured to change a basic motion of the knockout pin according to contour of the cam to a target motion obtained from the target angle information.

摘要： The lower part of a material to be molded forms a lower, seal with a die. A punch applying a molding force to the material forms an upper seal with the perimeter of the die. The space between the upper and lower, seals forms a pressure chamber that is filled with a fluid. As the punch descends into the die, the fluid is pressurized. The lower seal is a complete seal to prevent leakage of fluid into the die. The upper seal is given a clearance with the die that permits controlled leakage of fluid therepast at a rate that limits the maximum pressure in the pressure chamber while permitting the development of an adequate pressure on the material being molded.

摘要： A slide drive device for a press changes a slide stroke without a changing either a top or bottom dead center position of a slide. The slide drive device allows stroke adjustment without a loss of left-right balance in the slide drive device. An adjusting mechanism is driven by an eccentric part and a crank shaft. The adjusting mechanism is adaptable to fix either the top or bottom dead center position. A linear guide mechanism, is driven by the adjusting mechanism, and transfers adjustments in slope angle into changes in stroke relative to either the top or bottom dead center position without requiring a change in the dead center position. Alternate embodiments allow positioning and adjustment for convenience and economy.

摘要： The setting of parameters in a transfer press is simplified by inputting pattern information to an interference checker. From the pattern information (stroke of each shaft, slide stroke and the like) the interference checker simulates the movement conditions of the die, fingers, and product shapes to check the interference status. The pattern information is sent to the transfer press. Also, interference is simulated for display or printing before actual press operation is required.
