Referring to Figures 3 and 4 the action of the eyelet attached press device 100 configured as described above is as follows.

When the feed rod 142 of the first cylinder 141 is lowered in the raised state on the die 120 fixedly installed on the upper surface of the table 111 of the press body 110, the link rod 142 is coupled to interlock with the transfer rod 142. The lower end of the punched shaft 130 is pressed by the forge to pass the hole in the forge while passing through the punching hole 121 of the die 120.

Then, when the transfer rod 142 of the first cylinder 141 is elevated, the punching shaft 130 punched a hole in the forge is separated from the hole of the forge and is returned to its original position.

After the upper eyelet is inserted into the hole of the drilled forge, and the lower rod is inserted into the eyelet seating hole 122 of the die 120, the transfer rod 167 of the second cylinder 163 is raised, and the transfer rod ( Rotating arm 162 coupled to interlock with the 167 is rotated counterclockwise around the hinge axis 161, and at the same time the eyelet pressing housing 150 coupled to the front end of the pivoting arm 162 Is lowered and the eyelet pressing block 151 coupled to the lower end of the eyelet pressing housing 150 is coupled to the lower eyelet by pressing the upper eyelet fitted in the forge.

As described above, according to the present invention, the press device with the eyelet is punched by the first cylinder and the second cylinder, and the punching shaft and the eyelet pressurizing housing are raised and drilled, and then the eyelet is pressurized by pressing the eyelet into the hole. Since the process of attaching the let is done in one die fixedly installed on the table of the press main body, there is no movement of the forge placed on the table of the press main body, thereby effectively attaching the eyelet to the forge.

In addition, the structure of the lifting means is simpler than the press mounting device with an eyelet, which is composed of a plurality of cam wheels and cams, a cam receiver, a cam lever, and the like, which are linked by an electric mechanism to elevate the punching shaft and the eyelet pressure housing. It is easy to carry out maintenance and repair as well as to reduce the volume of the device, thereby simplifying the transport, and also reduce the cost of the device and products, thereby improving the price competitiveness.

In addition, as the cam wheel interlocked by the electric mechanism and the cam and the cam receiver are rotated in contact as in the prior art, the cam lever operates the punch up and down, and the mold tray is repeatedly reciprocally transferred by the crank wheel to make the punch and the mold. Rather, the punching shaft and the eyelet pressurizing housing are lifted by the first cylinder and the second cylinder separately provided to drill the hole in the forge, and then the eyelet is attached to the hole by pressing the eyelet. Since both punching and pressing are done in the die, the time can be shortened to maximize the efficiency of attaching eyelets to the forge.
