Eavestrough Outlet Cutter
20170368591 · 2017-12-28 ·

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.

A guide member includes a first diametrically directed side guide section and a second diametrically directed side guide section formed by bending a single member at a bent portion. The first diametrically directed side guide section guides predetermined portions of electric conductors on a diametrically directed side of a slot. Further, the second diametrically directed side guide section guides predetermined portions of the electric conductors on a diametrically directed side of another slot adjacent to the slot. The bent portion is supported by a supporting body.

Forged Wheel Trimming Die
20170291210 · 2017-10-12 · ·

An improved forged wheel trimming die, including a connecting rod, a lower die base lower plate, a bottom plate, a stripper guide pillar, a knockout rod, an ejector block, a lower die base stiffened plate, a lower die base upper plate, a lower die, a stripper plate, follow-up retainer plates, a shearing blade and a trimming rod. The improved forged wheel trimming die has the advantages that by adding two follow-up retainer plates to the stripper plate of the die, burrs of a forged wheel blank are constrained along the radial direction during the cutting, thereby avoiding breakage due to excessive deformation; in this way, the burrs can be protected from damage and knocked out successfully by the knockout rod after being cut off from the blank.

Machining planar workpieces

A machine for machining, such as cutting and/or forming, planar workpieces has an upper tool and a lower tool that are movable toward each other to machine a workpiece arranged therebetween. The upper tool includes at least one cutting tool having at least one cutting edge and a clamping shaft. The lower tool includes a main body having a support surface for the workpiece. The support surface has an opening associated with an inner counter cutting edge. The lower tool has a positioning axis and at least one outer counter cutting edge provided outside of the opening and associated with the support surface. The outer counter cutting edge is aligned with an outer face of the support surface. A distance of the outer counter cutting edge from the position axis and a distance of the inner counter cutting edge from the position axis deviate from each other.

Method of positioning and fixing of stator core and apparatus for same

A positioning and fixing apparatus that fixes a position of a stator core includes a plurality of positioners that are displaced so as to approach or separate from the stator core, by a positioner displacing unit. One of the positioners is an engager that engages with a first tab section being an engaging section. First, the engager engages with the first tab section, and then, pressers being the remainder of the positioners position a certain region of the stator core.

BREADMAKING TRAY AND MANUFACTURING METHOD THEREFOR

A breadmaking tray includes a breadmaking tray body B in which: (i) a fluorine resin film 2 having a thickness of 75 to 500 μm is laminated on a metal substrate 1 through heat bonding; (ii) a plurality of holes h are punched; and (iii) an appearance thereof has a plate shape bent in a corrugated form, and the breadmaking tray can further include a frame A for supporting the body B. A method for manufacturing the breadmaking tray is provided. The breadmaking tray has excellent release properties since flour dough comes into contact with only the inner walls of holes h punched in the fluorine resin film having excellent release properties during a breadmaking process, without coming into contact with the inner walls of holes h punched in the metal substrate.
