TL;DR: An improved stamping device including a porous stamping block adapted to remain in a retracted position above the lower edges of an outer frame as long as the device was not used, so that the block will not touch and stain an adjacent object.
Abstract: An improved stamping device including a porous stamping block adapted to remain in a retracted position above the lower edges of an outer frame as long as the device is not used, so that the block will not touch and stain an adjacent object, and be lowered to the lower edges of the outer frame, thereby permitting impression, and means for enabling continuous use of the device without use of a stamp pad.

TL;DR: In this paper, the effect of typical control parameters, such as blank holder pressure, friction coefficient, punch radii and die radii, on the springback robustness when forming a semi-cylindrical channel from Dual Phase steel through finite element method was investigated.

TL;DR: In this article, the effect of the operating parameters (i.e., step size, tool size, and forming speed) on the formability of a titanium sheet was investigated.
Abstract: Single-point incremental forming (SPIF) has the potential to replace conventional sheet forming processes for customized and small batch size sheet metal products. In this research work, the operating parameters (i.e. step size, tool size, and forming speed) which can affect the formability during SPIF process were altered over wide ranges and their effect on the formability of a titanium sheet was investigated. A six-dimensional hyper-surface showing the influence of investigated parameters on the formability was developed by using a response surface methodology. The capability of the SPIF process to enhance the cold formability of titanium sheet was also examined. This was carried out by comparing the sheet formability in SPIF and stamping processes.

TL;DR: In this paper, a solid cylindrical steel blank is heated to forging temp. and is placed on a friction press, and all gear teelh of the spur gear can be forged by one hammering, and then the above-mentioned material is passed through the processes of annealing and removing scale, and on the tooth-surface, there is a small quantity of metal allowance.
Abstract: A solid cylindrical steel blank is heated to forging temp. and is placed on a friction press, and all gear teelh of the spur gear can be forged by one hammering, and then the above-mentioned material is passed through the processes of annealing and removing scale, and on the tooth-surface, there is a small quantity of metal allowance, and then it is passed through such processes of cold-pressing and finishing on a hydraulic press, and the metal allowance of the tooth-surface is extruded to the tooth-end, so that the tooth-surface has no need of cutting machining, and all the gear teeth can be finally formed. The devices implementing the precison forging and cold pressing procedures are respectively new cylindrical gear precision forging and pressing dies.
