| An outlet cutter for cutting an outlet opening in an eavestrough has a frame including a trough opening therein arranged to receive the eavestrough therethrough. A female die including a die opening is supported on the frame directly below the trough opening so as to be arranged to be located directly below an eavestrough received through the trough opening. A male die is supported on the frame so as to be movable relative to a female die between a disengaged position spaced above the female die and a punching position fully received within the die opening in the female die using a screw. The frame is self-supported on the eavestrough for sliding. The male die has four corner portions, each formed by two side cutting edges which are sloped downwardly and outwardly towards a respective apex, with two opposed apexes protruding beyond a remainder of the die. | ||||||
| 176 | LOW PROFILE PILOT ASSEMBLY AND METHOD FOR METAL FORMING DIES | US15176196 | 2016-06-08 | US20160288190A1 | 2016-10-06 | Joel T. Pyper; Scott M. Breen |
| A pilot assembly and method for metal forming dies has a generally cylindrical pilot with a stripper that strips stock from the pilot when metal forming dies diverge. The pilot assembly is secured to one die member by a fastener by itself or in combination with a window mount. A spring within the pilot assembly contacts the stripper to force the stripper to reciprocate when the dies are pulled apart. Thus, the pilot assembly helps locate the stock within the metal forming die while also having a stripper to help strip the stock from the pilot. | ||||||
| 177 | PILOT ASSEMBLY HAVING STRIPPER | US13855347 | 2013-04-02 | US20130255350A1 | 2013-10-03 | Peter Nikolaus Schneider; Richard Everett Del Grosso, II; Shrinidhi Chandrasekharan; Frederick Charles Wilkinson |
| A pilot assembly includes a body portion including an outer surface and an opening defined in the outer surface. A pilot is configured for extending through an alignment hole in a sheet of material and is coupled with the body portion. A shaft of the pilot extends through the opening and beyond the outer surface. A stripper includes a bushing and a resilient biasing member. The bushing is configured for moving with respect to the main body portion and the pilot to push the sheet of material off of the pilot. The resilient biasing member is situated within the body portion and is compressed when the bushing engages the sheet of material. | ||||||
| 178 | Stripping device | US10522078 | 2003-07-25 | US08225702B2 | 2012-07-24 | Harald Weigelt |
| In the case of a stripping device (3) for use with a cutting tool (1) with a cutting element, in particular a punch (2), for machining a workpiece, in particular a curved metal sheet (6), at least one fastening piece (4, 28, 40) for fastening it to the cutting tool, a spring-elastic element (21) arranged outside the workpiece contact region, a stripping element (15, 34) which comes into contact with the workpiece and surrounds the cutting element (2), and at least one guide element (11, 26, 33) guiding the stripping element (15, 34) being provided, a device for securing against rotation is provided to essentially prevent the stripping element (15) from rotating. | ||||||

| A machine tool for processing workpieces includes a processing device from which processed products to be discharged can be produced from a workpiece; and a discharge device including a discharge flap that can be pivoted into a discharge position inclined downwards relative to a horizontal position in order to discharge processed products and which defines a discharge direction in the discharge position, the discharge flap comprising a part support disposed along the upper side of the discharge flap along which the processed products move during discharge in the discharge direction, where the part support has at least two support regions which extend in the discharge direction and which are configured to accommodate different types of processed products. | ||||||

| A stamping system comprising a press system including a plurality of bolsters, and a chute system disposed below the press system. The chute system communicates with the press system via a plurality of through-holes formed in the bolsters. In this manner, parts manufactured using the press system may pass through the bolsters into the chute system. | ||||||
