Production Technology

Considering the heavy strain of the machine, it is made of durable materials such as steel and spruce beams. The basement is made of a 22 mm MDF board and a non-combustible cement-bonded particleboard. The main frame and the stand of flywheel is welded, the other parts are mostly connected by screws and joints that allow the easy maintaining or replacing the wore out parts.

Design Challenge

While Slovakia has a long-time tradition of engineering industry including the production of heavy power hammers, there is a lack of smaller machines allowing blacksmiths as well as enthusiasts work at their garage or workshop. The design is focused on simplicity and easy maintenance, therefore the purpose was to build a power hammer using commonly available consumer goods and limit the amount of custom-made parts.

Inspiration

As a free-time blacksmith I was looking for an upgrade from elbow grease hammering to a power hammer. Also I got to know that many of jewellery makers as well as professional blacksmiths experience the lack of this kind of light power hammer. This is why I wanted to develop a practical machine that saves me and other blacksmiths from the hardest work and at the same time is very easy to maintain.

Project Duration

The project started in July 2018. The first prototype was finished in October 2018 and the final design was finished in January 2019 in Trstice, Slovakia.

Operation Flow

The machine is driven by an electric motor, but the
steering is enabled by a treadle that is bent around the base. The machine can be controlled by a single step on the treadle from any position, regardless the workshop's arrangement. As the force is adjustable, the user can also regulate the force between a very light tap and a hard strike. The strength of the power hammer lies
in simple and safe operation, low power consumption, easy maintenance and mobility.
