Abstract: A knuckle bracket includes a bracket main body that has an inner peripheral shape along a tube of a shock absorber and a pair of attachment parts that are formed to protrude parallel to each other. The apparatus for manufacturing the knuckle bracket includes a width molding machine that molds a width of the pair of attachment parts in a state where the workpiece is supported on a support shaft, and a hole punching machine that machines attachment holes into the pair of attachment parts in a state where the workpiece is supported on the support shaft. The workpiece is transported from the width molding machine to the hole punching machine by moving the workpiece along the support shaft until the workpiece is above the die after the support shaft is raised and then lowering the support shaft until the support shaft abuts a top surface of the die.

Abstract: 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.

Abstract: The present disclosure relates to a chair tray and chassis, chassis forming method and chassis mounting structure of the same. The chair chassis comprises a chassis body that is arranged with a mounting hole thereon for mounting a regulating knob. The edge at the position corresponding to the mounting hole of the chassis body is arranged with a flange. The structural strength and the fatigue strength of the chassis can be enhanced effectively by arranging the flange at the position corresponding to the mounting hole of the chassis, which avoids the occurrence of fracture at the perimeter of the mounting hole of the chassis during use or test and thus enables the thickness of the chassis to be reduced below 3 mm, reducing production material to a very large extent and saving production cost while also ensuring that it can pass the back pad fatigue test in the BIFMA standard.

Abstract: A stamping tool for stamping a product having an extending portion includes an upper mold having an inserting punch of which a bottom end defines an inclined pressing surface exposed under the upper mold, and a lower mold including an adjusting element, a sliding block, a returning block, a returning bolt and an elastic element. The returning bolt is inserted in the elastic element, and then screwed in the sliding block through the returning block. The sliding block is slidable between the returning block and the adjusting element and has one corner provided with an inclined abutting surface. The inclined pressing surface presses the abutting surface to push the sliding block and the returning bolt to slide towards the adjusting element so as to make the extending portion clipped between the sliding block and the adjusting element for modulating the product.
