特徴とする板金部材の接続装置。 A burring punch for forming burring holes is vertically movably mounted on the lower surface of the upper mold which is vertically movably mounted on the press ram, and is supported vertically movably under the upper mold by an appropriate cushion device. In addition, a cushion table having a burring die corresponding to the burring punch on its upper surface is arranged with the upper surface of the cushion table facing the lower surface of the upper mold, and the upper mold is directed toward the cushion table. By lowering the cushion table, a burring hole can be integrally formed in a plurality of sheet metal members placed in an overlapping manner on the cushion table. An insertion punch is attached to the stand in a state facing the burring punch, which acts to cause the bent portion of the burring hole of the sheet metal member to be rolled up in the radial direction when the upper die is lowered, and is attached to the upper die. The pressing force of the upper mold of the burring punch is applied to the cam surface of the first cam, which is supported vertically and movably and whose descent is stopped by the base after the burring hole is formed by the burring punch. A second cam having a cam surface that functions to release the cam surface is pressed into contact by the biasing force of a spring, and when the upper die is lowered in a state where the lowering of the first cam is stopped, the first cam is The second cam is horizontally moved by the cam surface to release the pressing force from the upper mold against the burring punch, and the bent portion of the burring hole of the sheet metal member is rolled up by the winding punch. What is claimed is: 1. A connection device for sheet metal members, characterized in that the device is configured to
