摘要： A handheld punch tool includes a housing, a die holder coupled to the housing, a die supported by the die holder, the die and the die holder defining a feed slot therebetween for receiving a workpiece to be cut, and a punch configured to reciprocate within the die holder, with a main body defining a first longitudinal axis extending centrally through the main body and a punch element extending from the main body along a second longitudinal axis parallel to the first longitudinal axis. The punch element is configured to cut a first distance into the workpiece per stroke of the punch when the feed slot faces a first side of the punch and to cut a second distance into the workpiece per stroke when the feed slot faces a second side of the punch opposite the first side. The first distance is greater than the second distance.

摘要： A multifunction punch apparatus, which can arbitrarily set a sheet size and a punch hole number and punch accurate punch holes with right and left margins of a sheet balanced, wherein information as to the sheet size, a punching direction, and the punch hole number is input from a manipulation panel to a controller; a traveling of a timing belt on which a head is mounted is controlled by controlling a control motor disposed in a manipulation unit cover to determine a movement position of the head; a sheet inserted between a punch guide unit and a guide member is punched by moving a hole punch vertically through a gear and a punch drive gear by driving a spline shaft; and when lengths of the right and left margins of the sheet in which a predetermined number of holes are punched are different, the length of the left margin is corrected by manipulating increase/decrease switches to correct a position of a first punch hole from a left side of the sheet.

摘要： A punch, in which two operations, e.g., the movement of a head 1 along a rail 4 and the vertical movement of a punch 32 are carried out by the rotation of a slide transmission shaft 2 is provided, so that the bad influence of the inertia of the head 1 is suppressed, and the high speed operation is realized to thereby enhance the punching operation. The punch of the present invention comprises, a slide transmission shaft 2 to engage with a head 1, a driving member 28 having concentrically a helical cam 281 consisting of a helical portion and a vertical portion on its outer circumference and a punch driving gear, a rack 31 being parallel with the slide transmission shaft 2 and having teeth of the pitch identical with the pitch of the helical cam 281, while being engaged with the rack 31, and a punch driven gear 30 being rotated while being engaged perpendicularly with the punch driving gear 29 and having a pin 361 to be engaged with a rectangular hole 331 of the punch driving member 29. So that the head 1 is displaced along the rack 31 while the helical portion of the helical cam 281 is engaged with the rack 31. And an up-down movement of the tip end of the punch 10 is carried out with an area of punching process while the vertical portion of the helical cam 281 is engaged with the rack 31. Further, the head displacement and stoppage and the up-down movement of the punch are completely synchronized with the pitch of the holes to be punched.

摘要： A gasket punch of the instant invention includes a frame having a grip integrally formed therewith, a piston chamber located ahead of the grip, and a die platform spaced beneath the piston chamber, also ahead of the grip. The punch includes a fluid connector for connecting the punch to a pressurized fluid supply. A piston and shaft are mounted for reciprocating movement in the piston chamber and are operable to receive a punch element on the free end of the piston shaft. Punch and die elements are provided to form holes of various sizes. The punch and die elements are interchangeable. A resilient stripping element is provided for each punch element to remove the punched gasket material from the punch element. An adjustable bail and plural guide elements are provided to accurately position the punch relative the gasket material to be punched. A trigger valve is provided to connect the fluid supply with an upper portion of the piston chamber, thereby causing the piston to move downwards, carrying the punch element therewith and forming a hole in the gasket material.
