20130340586 | PUNCHING DEVICE - A punching device includes: a die seat; a punch seat; an interconnecting member interconnecting a first end portion of the die seat and a first end portion of the punch seat; a punch supported movably on the punch seat; a first pivot part extending from at least one of the first end portion of the die seat and the first end portion of the punch seat; a second pivot part extending from a second end portion of one of the punch seat and the die seat; a lever mechanism including first and second levers, the first lever being pivoted to the first pivot part, the second lever being pivoted to the second pivot part for pressing one end of the first lever; and an urging member for urging the punch away from the die seat. | 12-26-2013 |
20140230624 | PUNCHING DEVICE - A punching device includes: a die seat; a punch seat; an interconnecting member interconnecting the die seat and the punch seat; a punch; first and second pivot parts; a first lever pivoted to the first pivot part and having two first side walls and two side flanges that extend respectively from lower ends of the first side walls; a second lever pivoted to the second pivot part and having two second side walls that abut against the side flanges for driving rotation of the first lever relative to the first pivot part; and an urging member for urging the punch. | 08-21-2014 |
083588000 | Through return (noncutting) stroke | 7 |
20080264226 | PUNCH UNIT - For automatic return control of the punch blades, the punch blades are returned to the home position after one failure by making a retry in an inverse direction or by storing the driving phase when the last driving ended and by rotating the punch blade in a direction inverse to the direction in the phase at the end of the driving. | 10-30-2008 |
20090133560 | Paper punch - A desk-top paper punch includes a drawer for removable insertion into the base of the paper punch, the drawer serving as a collection receptacle for paper punches to be discarded. Once the drawer is near its capacity, the drawer is pulled out of the base for emptying. Means for viewing the contents of the drawer is provided. In one implementation, the view means is a transparent window which allows the viewer to know when the drawer in nearing its capacity for paper chips. In a second embodiment, the viewing means is at least one viewing aperture that perforates the top surface of the base of the paper punch that allows the user to view the drawer's contents. | 05-28-2009 |
20090193951 | Modular spring retainer and method for metal forming dies and the like - A modular spring retainer and method for metal forming dies includes a base shaped for detachable connection with an associated die plate, having a threaded central aperture, and an adjacent lock dowel aperture which extends through the threaded central aperture to form a window. A cylindrically-shaped spring retainer is configured to receive a spring therein, and has a threaded exterior portion which engages the threaded central aperture of the base, such that mutual rotation of the same adjusts the longitudinal position of the spring. A locking dowel is closely received in the lock dowel aperture in the base, and has an unthreaded exterior surface which protrudes through the window and abuttingly engages an adjacent portion of the threaded exterior surface of the spring retainer to securely, yet detachably, retain the spring member in a selected longitudinal position. | 08-06-2009 |
20130319198 | CONTROL DEVICE FOR PAPER PUNCH - A paper punch includes multiple punch units, a cover and a slide member. Each paper unit has a punch body and a blade, the punch body has a passage through which the blade is movable relative to the punch body by the spring. The blade has a passive tooth on the top thereof. The cover is mounted to outside of the punch unit and has a closed top in which a slide slot is defined. The slide member is slidable along the slide slot and has an active gear which is engaged with the passive tooth of the punch unit. When moving the slide member, the blade is lowered because the active gear drives the passive tooth. The cross section of the blade is changed to punch different shapes of holes through the paper sheets. | 12-05-2013 |
20140026729 | Return device for returning punch head of paper punch - A paper punch includes at least one punch head unit connected to a base and the at least one punch head unit has at least one punch head located therein. At least one resilient plate is cooperated with the at least one punch head. The first end of the at least one resilient plate is fixed to the at least one punch head unit and the second end of the at least one resilient plate is bent for form a connection end. An operation portion is connected between the first end and the second end of the at least one resilient plate. The connection end contacts a lower lateral side of a front pin extending transversely through the at least one punch head. The at least one resilient plate brings the at least one punch head upward after each punching action. The at least one resilient plate occupies less space and is easily installed. The paper punch is safe and easily assembled. | 01-30-2014 |
20150107431 | CORNER TRIMMER - A corner trimmer includes a base, a bottom blade, an L-shaped operation member, a top blade and a spring. The base has a platform and a pivotal portion. The bottom blade having a round edge is fixed to the base and parallel to the platform. The two ends of the L-shaped operation member and two ends of the pivot of the pivotal portion are connected to the base. The L-shaped operation member has an opening. The top blade is located at the inside of the L-shaped operation member and has a curved edge which is located corresponding to the round edge of the bottom blade and shaped to be complementary to the round edge. The spring is biased between the base and the top blade. The corner of an object is inserted into the opening and trimmed by the alternative top and bottom blades. | 04-23-2015 |
