摘要： A fluid cylinder mechanism (1) equipped with a cylinder (10) having a base end (12) and an open end (11), and a piston (20) having a flange portion (21) disposed inside the cylinder and a rod portion (25) that passes through the open end of the cylinder, in which a space inside the cylinder is partitioned by the flange portion of the piston into a first pressured chamber (14) on a side of the base end and a second pressurized chamber (15) on a side of the open end, is characterized by including: a first flow path (22) that permits flow of a fluid from the first pressurized chamber to the second pressurized chamber; a second flow path (32) that permits flow of the fluid from the second pressurized chamber to the first pressurized chamber; and an opening and closing means (35) for opening and closing the second flow path.

摘要： A fluid spring is provided with a sleeve, a first chamber configured to accommodate a fluid and formed in the sleeve, a hollow piston rod, a second chamber configured to accommodate the fluid and formed in the hollow piston rod, and a communicating passage configured to make the first chamber and the second chamber communicate with each other and formed in an end portion of the hollow piston rod. A part of the hollow piston rod is displacably accommodated in the first chamber. The communicating passage only permits the fluid to flow in a direction from the first chamber to the second chamber.

摘要： A movable die is provided to be displaceable in an upper die. When the upper die is moved downward to press a steel plate together with a lower die, only the movable die first abuts on the steel plate to carry out forming together with the lower die. Then, the upper die is further moved downward to form a part which has not been formed by the movable die.
摘要翻译： 提供可移动模具以在上模具中移动。 当上模向下移动以与下模一起挤压钢板时，只有可动模首先与钢板邻接以与下模一起进行成形。 然后，上模进一步向下移动以形成未被可动模具形成的部分。
