PORTABLE PULSE HEAT SCISSORS Russian patent published in 2018 - IPC B23D15/04 B23D15/12 

FIELD: metallurgy.

SUBSTANCE: scissors comprise an upper movable blade attached to a slide that is connected to a piston located in a cylinder on the end of which a chamber with a trigger mechanism is disposed. In this case, they are equipped with a recharge mechanism attached to the chamber, and two lower stationary blades arranged parallel to each other at a distance equal to the width of the upper blade, guide, to one part of which are attached lower blades, at the end of which there is an end blade, and to the other – a cylinder, and a bridge connecting these parts of the guide. In this case, the blades are made with the ability to cut the slots to advance the scissors and then cut down into the metal. Scissors can be provided with a restraining ring and are configured to dampen the impact of the piston against said limiting ring by compressing air located in the pre-spin space.

EFFECT: expansion of technological capabilities is achieved by removing restrictions on the length of the cut.
