An adaptor for a press. The adaptor includes a body adapted to removably couple to the press cylinder or carriage of the press and an extension shaft having first and second opposing ends. The first end is removably coupled to the body, and the second end is adapted to couple to a drive adaptor.

A safety power assist for a manual press is provided. In another aspect, a press includes a tool, a manual actuator, a switch and an automatically powered actuator. A further aspect of the present press employs a spring which must be compressed beyond a predetermined pinching force before a switch is activated, where switch activation causes an automatically powered actuator to advance a workpiece-contacting punch or tool.

A securement device for a press tool including an angular exterior body having a side wall. A multitude of ratcheting bodies are located around a top edge of the exterior body. The ratchets include a ratchet bar. The ratchet bar has a plurality of ratchet grooves that allow the ratchet bars to be slide inward toward the interior of the exterior body and to be locked into place. An interior body is located within the exterior body such that it can be moved about and provide extra support for the ratchets.

Retrofit systems for converting a manual press to an automated press. The retrofit systems include a first shaft, a second shaft, a first spacer, and a second spacer. The first shaft is mounted to a first vertical member and is coupled to a first cross member and to a second cross member. The second shaft is mounted to a second vertical member and is coupled to the first cross member and to the second cross member. The first spacer is supported by the first shaft and is disposed between the first vertical member and the first cross member. The second spacer is supported by the second shaft and is disposed between the second vertical member and the first cross member. The first spacer and the second spacer are selected to increase the space between the first cross member and the second cross member to accommodate an automatically actuated press.

A hydraulic powered press for hand tool repair is mounted to a wall and powered by an electric motor. A plurality of adjustable holders is secured about the side frame of the jack.

Provided is a device for improving perovskite film formation uniformity, including a grinder and a sheeter, wherein the grinder grinds a perovskite precursor into a powder, the sheeter presses the ground precursor powder into a precursor sheet, the sheeter includes a mold for pressing the precursor powder and a heating device, and the heating device heats a lower mold. A method of using the above device for improving perovskite film formation uniformity, and a method of preparing a perovskite solar cell are also provided. The precursor sheet prepared herein not only solves the problems of uneven particle size and uneven spreading at the bottom of the evaporation source or incomplete coverage, but also prevents splashing during vacuuming and aeration, and meanwhile, since the precursor powder is compacted, it is more conducive to the uniform conduction of heat during the heating and evaporation process, thereby improving the heat energy use efficiency.
