MECHANICAL ENGINEERING SENIOR DESIGN PROJECT

Abstract: Wendell August Forge, est. 1923, is one of America’s oldest and finest metalcrafters. One of their most beloved

products is their hand-designed annual Christmas ornament. With the popularity of this product, Wendell August

desired to produce a higher volume of these ornaments and charged senior Grove City College mechanical engi-

neers with designing an automated hammering prototype to be used as the basis for a future production machine.

Building off of the single-ornament hammering unit created by the previous year, the second-year team solved addi-

tional automation challenges by developing four key systems: the feeding, punching, clamping, and linkage sys-

tems.

Clamping The clamping system holds the sheet firmly to the die as

each ornament is hammered. It is actuated by a pneumatic cyl-

inder that engages the clamp after the feeding system releases

the sheet. This permits the alignment table to move the material

to the correct locations for hammering and stamping.

Feeding Aluminum stock (thickness: 0.090”) is roll-fed into the

machine via a nip roller system. The bottom roller is made of

precision-ground steel and driven by an Aerotech servomo-

tor. A pneumatic cylinder moves the upper, urethane roller

vertically to engage or disengage the system depending on

the state of the other operations. When engaged, the system

precisely feeds stock into the machine.

Linkage Wendell August Forge desired for the project to operate

without exceeding excessive noise levels - i.e. run in an office-

like environment. The crank and toggle system was

developed to provide the necessary forces while remaining

quiet and efficient. The hammer block was designed to

include an offset stamp for impressing the Wendell August

Forge logo into the back of each ornament after hammering.

Punching Indexing each hammered ornament is crucial to locating

the ornament in subsequent operations. A 4 1/2” pneumatic

cylinder actuates a punch that creates a 1/4” index hole for

each ornament as the stock feeds through. These index holes

align with pins on the die and will also be used for blanking

operations in the future.
