摘要： PROBLEM TO BE SOLVED: To provide a hydraulic pipe expanding and forming machine which can be incorporated into the progressive die and the transfer die of a general purpose press without the need of a hydraulic pressure generating device.
SOLUTION: When an upper die 1 starts lowering and the oil injecting hole 10 of an upper die knockout 2 passes through the upper end of a workpiece 6, an oil supply unit 20 starts supply of the oil and the oil is supplied to the inside of the workpiece 6 from the oil injecting hole 10 of the upper die knockout 2. In timing when the oil injecting hole 10 of the upper die knockout 2 enters the inside of the upper die 1, the oil supply unit 20 stops the supply of the oil and the oil injecting hole 10 is closed by sinking of the upper die knockout 2 into the upper die 1 and sealed. After that, when the upper die is further lowered, the oil 13 which is confined in the workpiece 6 is compressed by lowering of the upper die 1, the workpiece 6 is expanded outward and the expansion and formation of the workpiece 6 are performed.

摘要： PROBLEM TO BE SOLVED: To provide a side surface punching apparatus capable of performing highly accurate punching work by equalizing a clearance between a punching punch and a punching die.
SOLUTION: A press component 2 is loaded on a fixing pedestal 3, an upper die 6 moves down, a punching die 11 enters the inside of the press component 2, and a punch plate 7 moves down. Thus, a slide cam 5 is pressed by a cam 10 and slide, and the sides surface of the press component 2 are punched by the punching punch 4 and the punching die 11. As described above, the slide cam 5 having the punching die 11 and the punching punch 4 fixed thereon are incorporated in the upper die of the molding die, and even if a stroke of the press is unstable, the positional relation between the punching punch 4 and the punching die 11 can be made stable.
