Synchronous servo feeding system for punching machine and method for operating the same

Abstract

The present invention provides a synchronous servo feeding system for punching machine and the method for operating the same. According to the present invention, a servo feeding device is provided on one side of a punching machine for guiding a material strip into the punching machine for processing. In addition, a servo pulling device is provided on the other side of the punching machine for conveying a finished strip from the punching machine. Besides, a central servo control system is provided for controlling the servo feeding device and the servo pulling device. Thereby, the material strip can be fed and pulled synchronously.

What is claimed is: 
     
         1 . A method for operating a synchronous servo feeding system for punching machine, comprising steps of:
 using a servo feeding device disposed on one side of a punching machine to guide a material strip to said punching machine for processing; and   using a servo pulling device disposed on the other side of said punching machine to convey a finished strip from said punching machine;   where said servo feeding device and said servo pulling device are controlled by a central servo control system for guiding and conveying said material strip and said finished strip synchronously.   
     
     
         2 . The method for operating a synchronous servo feeding system for punching machine of  claim 1 , wherein the thickness of said material strip is between 0.01 and 0.2 millimeter. 
     
     
         3 . The method for operating a synchronous servo feeding system for punching machine of  claim 1 , wherein said servo feeding device and said servo pulling device are identical devices. 
     
     
         4 . A servo feeding device, comprising:
 a frame;   a guiding base, disposed on said frame;   a clamp set, including a fixed clamp and a movable clamp both passing through said guiding base;   a servo module, including a first servo driving device and a second servo driving device disposed corresponding to said fixed clamp and said movable clamp, respectively; and   a guiding device, connected with said movable clamp, and driving said movable clamp to move back and forth.   
     
     
         5 . The servo feeding device of  claim 4 , wherein said fixed clamp and said movable clamp include a clamp unit, respectively, and said clamp unit includes a clamp piece. 
     
     
         6 . The servo feeding device of  claim 5 , wherein said clamp piece is a detachable clamp piece. 
     
     
         7 . The servo feeding device of  claim 5 , wherein said first driving device is connected with a first prop member; said first prop member is against said fixed clamp; said second driving device is connected with a second prop member; and said second prop member is against said movable clamp. 
     
     
         8 . The servo feeding device of  claim 7 , wherein said first prop member and said second prop member are against said clamp pieces of said fixed clamp and said movable clamp, respectively, for driving said clamp pieces to clamp or release a material strip. 
     
     
         9 . The servo feeding device of  claim 4 , wherein said guiding device includes a linear guiding rail and a linear motor; said movable clamp passes through said guiding base and is connected with a slider of said linear guiding rail; and said linear motor is disposed on the other side of said frame and connected with said slider. 
     
     
         10 . The servo feeding device of  claim 4 , wherein a guiding roller is disposed on one side of said guiding base for facilitating conveying a material strip.
