Figure 4 is a side configuration diagram of a flying cam type press device according to an embodiment of the present invention, the flying cam type press device according to an embodiment of the present invention, the end of the panel product is flanged in double by the first and second flange molding In the case of being formed in an undercut shape to form at the same time in one press apparatus, the configuration is provided with an upper die 101 and a lower die die 107 in the lower and lower operation.

The lower mold 105 supporting the material panel 103 at the lower portion of the upper mold 101 is mounted at one side of the lower mold die 107, and the lower mold steel 109 is configured at one end of the lower mold 105. .

In addition, between the upper mold 101 and the lower mold 105, the upper mold pad 113 is mounted on the lower side of the upper mold 101 through the cushion spring 111, and the lower mold pad at the lower portion of the upper mold 101 On the side of the 113, an operating driver 115 having a cam inclined surface 114 downward is mounted.

A cam unit is installed between the actuating driver 115 and the lower die 107 to perform cam operation by the lowering operation of the actuating driver 115. The cam unit is moved back and forth in response to the lower die steel 109. Is configured to work.

The cam unit has a lower cam driver 117 mounted upward on one side on the lower die 107 in response to the operation driver 115, and is connected to an upper surface of the lower cam driver 117. Cam guide surfaces 119 and 121 of different angles are formed, respectively.

In addition, a flying cam slider 125 is mounted on the cam inclined surface 114 of the operating driver 115 so as to be cam-operated through the guide means 123. The flying cam driver 125 has lower cams on both sides of the lower cam. A guide roller 127 is formed in rolling contact with the lowering and raising cam guide surfaces 119 and 121 of the driver 117, and is formed along the lowering and raising cam guide surfaces 119 and 121 of the lower cam driver 117. Cam driving in two inclined directions is achieved.

Here, the guide means 123 is configured with a guide block 133 on the cam inclined surface 114 of the operating driver 115, the slide on the guide block 113 on the cam inclined surface of the flying cam slider 125. The guide protrusion 135 guided and inserted into the guide is possible.

In addition, in response to the lower die steel 109, a flying cam steel 129 is mounted at one end of the flying cam slider 125.

The cam guide surfaces 119 and 121 of the lower cam driver 117 guide the lowering of the flying cam slider 125 to the first inclination angle through the guide roller 127 for the primary molding of the flying cam steel 129. An ascending type configured to ascend and guide the flying cam slider 125 to the second inclination angle through the guide roller 127 for secondary molding of the descending cam guide surface 119 and the flying cam steel 129 formed to The cam guide surface 121 is divided, and the connecting portion P of the lower cam guide surface 119 and the upward cam guide surface 121 is formed in a round shape.

Here, the first inclination angle ?? 1 of the descending cam guide surface 119 with respect to the reference horizontal line S has a cam inclined surface 114 of the operating driver 115 with respect to the reference horizontal line S. It is formed larger than the inclination angle (??), the second inclination angle (?? 2) with respect to the reference horizontal line (S) of the cam guide surface 121 for the ascension is the cam inclined surface 114 of the operating driver 115 is It is formed smaller than the inclination angle (??) with respect to the reference horizontal line (S).

In addition, a stopper 131 is mounted at an outer end of the operating driver 115 to support the outer end of the flying cam slider 125.

Therefore, the process for processing the undercut shape by double-molding of a panel product using the flying cam type | mold press apparatus which has the above structure is demonstrated through FIGS. 5-7.

First, as shown in FIG. 4, when the panel 103 to be molded is seated on the lower mold 105 and the upper mold 101 is lowered and operated, the upper mold pad 113 and the operating driver 115 move downward in association with each other. However, the upper mold pad 113 is first to regulate by pressing the panel 103 between the lower mold 105.

Subsequently, when the upper die 101 is lowered, as shown in FIG. 5, the flying cam slider 125 passes through the guide roller 127 to lower the cam guide surface of the lower cam driver 117. In contact with the top of the (119).

If the upper die 101 continues to move in this state, as shown in FIG. 6, the flying cam slider 125 simultaneously operates the cam with the actuating driver 115 and the lower cam through the guide roller 127. The downward cam guide surface 119 of the driver 117 is inclined to move to the lower left in the drawing. At this time, the flying cam steel 129, together with the lower die steel 109, ends of the panel 103. The first bent molding in the direction of the first inclination angle.

Subsequently, when the upper die 101 continues to move downward, as shown in FIG. 7, the flying cam slider 125 moves the lower portion through the guide roller 127 with the cam actuation with the actuation driver 115. Along the upward cam guide surface 121 of the cam driver 117 is tilted to the upper left in the drawing, the flying cam steel 129, together with the lower die steel 109, of the panel 103 The end is second bent in the second inclination direction.

Here, in order to proceed with the secondary bending molding after the primary bending molding by the progress of the cam operation of the flying cam slider 125, the guide roller 127 is the cam guide for lowering of the lower cam driver 117. The surface 119 and the rising cam guide surface 121 passes through the round-shaped connecting portion (P), thereby minimizing contact noise.

As such, after the flying cam type press device completes the molding operation, the upper die 101 moves upward with the operation driver 115, and thus the flying cam slider 125 moves the lower die 107. Is restored to the initial position.

As described above, according to the flying cam type press device according to the present invention, the flying cam slider driven by the cam by the actuating driver proceeds in contact with the lower cam driver having the lower and lower cam guide surfaces for lowering, and the secondary cam at the end. It is possible to reduce the two conventional processes by allowing the flange forming over the same in a single cam-type press, thereby reducing the mold manufacturing cost, thereby minimizing the product cost.
