Conveyor chain pin forming facility

Abstract

A conveyor chain pin forming facility includes a base, on which are installed a fixed bottom die device, a movable top die device and two movable side die devices. The side die devices are separately installed on two ends of the bottom die device. A metal object is placed inside the bottom die device. By closing the top die device and the side die devices onto the top side and two sides of the bottom die device, the metal object is compressed to form. The component thus formed has a smooth surface without protruded ribs, and the production process can be simplified.

1 . A conveyor chain pin forming facility, comprising: 
 a base;    a bottom die device fixed to the base having a bottom die hole at a specified location thereof;    a top die device movably installed onto the base having a top die hole at a specified location thereof, so that the top die device is corresponding to the bottom die device;    two side die devices separately and movably installed on the base;    wherein the die hole of the bottom die device serving to accommodate a metal object, the top die device moving toward the bottom die device until the top and bottom die holes are opposite each other, the two side die devices moving toward the top die device and the bottom die device, thereby a heated metal object is compressed to become a desired form by the closing movement of the top die device and the side die devices toward the bottom die device.    
   
   
       2 . The conveyor chain pin forming facility of  claim 1 , wherein when the top die device and the bottom die device are closed, there are openings on two ends thereof, and the side die devices have protrusions that extend into the openings.
