    摘要： A punch die is provided. The punch die includes a punch body, a punch guide configured to removably receive the punch body therein, a retainer collar detachably coupled to the punch guide, a punch head mated to the punch body to regulate a position of the punch body, and a spring interposed between the punch head and the retainer collar. The punch guide includes a peripheral slot defined on the internal periphery of the punch guide such that the peripheral slot intersects a keyway of the punch guide. The retainer collar includes a cylindrical projection that extends into the inner periphery of the punch guide and an engaging projection defined on an outer periphery of the cylindrical projection. The engaging projection is rotatable to engage the peripheral slot and to be releasably aligned with the keyway.

    摘要： A punch die includes: a punch body including a punch edge portion at a lower end portion along an axis, a key projecting from an outer periphery, and a punch driver at an upper portion along the axis; a punch guide including an inner hollow elongated along the axis and receiving the punch body to be movable along the axis, and a keyway formed on an internal periphery of the inner hollow to extend along the axis and mesh with the key; a retainer collar rotatably combined with the punch guide at an upper end along the axis and around the axis, the punch driver passing through the retainer collar to be movable along the axis; and a punch head screwed in an upper end portion along the axis of the punch driver to regulate a position of the punch driver.

    摘要： A punch die is provided and includes a punch body extending along an axial direction of the punch die and including a punch edge portion, a key, and a punch driver. The punch die also includes a punch guide configured to removably receive the punch body therein, the punch guide including an inner hollow that receives the punch body and a keyway that receives and guides the key. The punch die further includes a retainer collar detachably coupled to the punch guide and configured to permit the punch driver to pass therethrough and be movable along the axial direction. The punch guide includes a peripheral slot that intersects the keyway of the punch guide and the retainer collar includes a cylindrical projection and an engaging projection that is rotatable to engage the peripheral slot and to be releasably aligned with the keyway.
