The present disclosure relates generally to retrofit systems. In particular, retrofit systems for converting manual presses to automated presses are described.
Presses are utilized extensively in machine and fabrication facilities. Presses allow an operator to stamp, die cut, or otherwise process workpieces. Commonly, presses include a ram, a force multiplier, such as a hydraulic cylinder, and an actuator. Presses can include manually actuated force multipliers or automatically actuated force multipliers. Presses with manually actuated force multipliers are known as manual presses and presses with automatically actuated force multipliers are known as automated presses.
Manual presses are common because they are less expensive and less complex than automated presses. However, manual presses tend to be slow and require more labor than automated presses.
Automated presses are advantageous because they are much faster to operate than manual presses and require less labor. However, automated presses tend to be significantly more expensive than manual presses.
Due to economic factors, many machine and fabrication facilities initially opt to purchase a manual press. Over time, however, facility owners may wish to have an automated press in their facilities. Conventionally, acquiring an automated press requires purchasing a complete automated press to either replace the manual press or to be onsite along with manual press. Purchasing an automated press is economically inefficient given that core aspects of the manual press could still be used effectively to support an automatically actuated press.
It would be desirable to provide a means for facility owners to upgrade their manual presses to automated presses without having to purchase an entirely new automated press. Retrofitting an existing manual press to accommodate an automatically actuated press would be more economically efficient than replacing the existing manual press.
Thus, there exists a need for retrofit systems that convert a manual press to an automated press. Examples of new and useful retrofit systems relevant to the needs existing in the field are discussed below.

Features specific to a given example will be described in that particular example. The reader should understand that a given feature need not be the same or similar to the specific portrayal of a related feature in any given figure or example.
The following definitions apply herein, unless otherwise indicated.
“Substantially” means to be more-or-less conforming to the particular dimension, range, shape, concept, or other aspect modified by the term, such that a feature or component need not conform exactly. For example, a “substantially cylindrical” object means that the object resembles a cylinder, but may have one or more deviations from a true cylinder.
“Comprising,” “including,” and “having” (and conjugations thereof) are used interchangeably to mean including but not necessarily limited to, and are open-ended terms not intended to exclude additional elements or method steps not expressly recited.
Terms such as “first”, “second”, and “third” are used to distinguish or identity various members of a group, or the like, and are not intended to denote a serial, chronological, or numerical limitation.
“Coupled” means connected, either permanently or releasably, whether directly or indirectly through intervening components.
“Communicatively coupled” means that an electronic device exchanges information with another electronic device, either wirelessly or with a wire-based connector, whether directly or indirectly through a communication network.
“Controllably coupled” means that an electronic device controls operation of another electronic device.
Retrofit Systems for Converting Manual Presses to Automated Presses
With reference to the figures, retrofit systems will now be described. The retrofit systems discussed herein function to convert manual presses to automated presses.
The reader will appreciate from the figures and description below that the presently disclosed retrofit systems address the existing challenges facing machine and fabrication facility owners. For example, the retrofit systems provide a means for facility owners to upgrade their manual presses to automated presses without having to purchase an entirely new automated press. Retrofitting an existing manual press to accommodate an automatically actuated press with the retrofit systems below is more economically efficient than replacing the existing manual press because key components from the manual press can continue to be used.
By converting a manual press to an automated press, the press becomes faster to operate and requires less labor. These advantages are obtained at significantly lower cost with the retrofit systems below than would be required to purchase a new, conventional automated press.
Contextual Details

Manually Actuated Press Assembly
Manually actuated press assembly 104 serves to selectively exert compressive force on workpieces. Manually actuated press assembly 104 includes a ram 124, a force multiplier 125, and an actuator 126. Ram 124 moves in response to pressure exerted on it by force multiplier 125. In the present example, force multiplier 125 is a hydraulic cylinder.
Actuator 126 increases pressure in force multiplier 125 when actuator 126 is manually actuated. More specifically, actuator 126 increases pressure in force multiplier 125 when a user manually manipulates actuator 126 up and down to pump force multiplier 125.
The size of the manually actuated assembly press may be varied as needed for a given application. In some examples, the manually actuated press assembly is larger relative to the other components than depicted in the figures.
