20080271512 | Method for Making a Cold-Worked Article - In a method for cold-working a piping component ( | 11-06-2008 |
20100083726 | REACTION DEVICE FOR FORMING EQUIPMENT - An apparatus may have a cylinder including a piston rod and a chamber in which a working fluid is received to resist movement of the piston rod into the chamber, and an accumulator having a first chamber in communication with the cylinder chamber to receive fluid from the cylinder chamber upon movement of the piston rod into the cylinder chamber. The apparatus may also have a pressure controller having a fluid chamber where some of the working fluid may be received and an actuator operable to increase the volume of the fluid chamber when the piston rod is retracted into the cylinder chamber to increase the total volume in which the working fluid may be received, wherein the increased volume of the fluid chamber may accommodate fluid movement in the assembly not caused by movement of the piston rod. | 04-08-2010 |
20100116015 | DEEP-DRAWING DEVICE - A deep drawing apparatus is provided in which a sheet material is subjected to optimal heating and cooling, whereby the limiting draw ratio is increased and a product can be worked more deeply, and uniformity of the sheet thickness of the product can be controlled. This apparatus includes: a punch | 05-13-2010 |
20100313624 | DIE - A die includes a stationary die, a movable die, which is opposed to the stationary die and reciprocatable in a first direction to change a distance between the stationary and movable dies, and a transfer mechanism, which transfers a workpiece, upon which plastic deformation work is performed between the stationary and movable dies, in a second direction crossing the first direction. The transfer mechanism includes a clamp portion, which clamps/unclamps the workpiece, a synchronizing member, which is engaged with the movable die to reciprocate in synchronization with reciprocation of the movable die, a clamp-unclamp operation converter, which converts reciprocation of the synchronizing member into clamping/unclamping of the workpiece by the clamp portion, and an advance-return operation converter, which converts reciprocation of the synchronizing member into advance-return operation of the clamp portion, whereby the clamp portion advances the workpiece in the second direction and is returned after advancement of the workpiece. | 12-16-2010 |
20120240653 | FORGING MOLD - A forging mold includes a female mold and a male mold coupling with the female mold. The female mold includes an external mold defining an accommodating groove for receiving an internal mold and a pressing block therein, and a first fixing hole penetrating through the external mold and connected with the accommodating groove. The pressing block has a gap opened at a bottom portion thereof and adjacent to the internal mold. The internal mold has a base body and a blocking protrusion protruded from a bottom portion of the base body to be pressed in the gap. A first fixing element is screwed into the first fixing hole of the external mold with a distal end thereof resisting against the pressing block to further press the pressing block towards the internal mold so as to secure the internal mold and the pressing block in the accommodating groove. | 09-27-2012 |
20130239645 | METHOD OF PRODUCING L-SHAPED PRODUCT - A method of producing an L-shaped product ( | 09-19-2013 |
20140090440 | Method for Manufacturing a Damping Shaft Sleeve - This invention relates to a method for manufacturing a damping shaft sleeve that includes: forging a base material into a billet that includes a cylindrical body having two opposite ends and an annular flange formed on one of the opposite ends; forging a shaft hole in the cylindrical body; inverting the base material and forming two annular grooves that are respectively indented from two opposite surfaces of the annular flange; forging the billet to form the annular flange into a bottom wall and a side wall, the bottom wall cooperating with the side wall to form an asymmetrical and helical groove; and forging the shaft hole to pass through the cylindrical body of the billet. | 04-03-2014 |
20140208819 | DEVICE FOR SHAPING A METAL SHEET BY DIE STAMPING - A device for shaping a metal sheet by die stamping, the device including first and second trunnions configured to be fastened respectively to two opposite ends of a sheet, the sheet being configured to be shaped by die stamping, wherein the first and second trunnions define respective first and second bearing surfaces configured respectively to guide turning of the trunnions, the first bearing surface defining a peripheral groove around a pivot axis of the first trunnion while the second bearing surface is smooth along a pivot axis of the second trunnion. | 07-31-2014 |
20140318205 | PRESS SYSTEM AND VACUUM PORT ASSEMBLY THEREFOR - A vacuum port assembly is provided for a press system including a die assembly and a transfer assembly. The transfer assembly includes a conveyor belt, a vacuum manifold coupled to the die assembly, and an airflow generator. The conveyor belt includes a plurality of holes for receiving and moving shells in a plane with respect to the die assembly. The vacuum port assembly includes at least one port member including inlet and outlet ends. The inlet end has a mounting portion for removably coupling the port member to the vacuum manifold. The outlet end is in fluid communication with the airflow generator, thereby establishing fluid communication between the airflow generator and the vacuum manifold. The inlet end extends outwardly from the vacuum manifold generally perpendicular with respect to the plane of the conveyor belt. | 10-30-2014 |
20140366604 | FORGING METHOD AND FORGING DIE - A forging method according to the present invention is characterized by including the steps of placing a work W having a first shape which is a rectangular hexahedron in a work space | 12-18-2014 |
20150336158 | METHOD FOR PRODUCING PRESS-MOLDED ARTICLE - A method produces a press-molded article having a hat shaped cross-section with flanges at both sides, a top plate, vertical walls at both sides, and having a shape curved in the vertical direction to an inverted checkmark shape along the longitudinal direction when the molded article is viewed from a side face with the top plate section on the top side. An intermediate molded body is formed by drawing a metal stock sheet into an intermediate shape, and after preparing the outside shape of the intermediate molded body by trimming, drawing is subsequently performed to form the final shape. | 11-26-2015 |
