Magnetic Hold-Down Tool for Safe Shear Material Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current metal manufacturing machines, such as press brakes and shears, lack effective methods for controlling material, leading to safety issues and material waste, as operators rely on hand manipulation, which can result in injuries and inefficiencies when working with smaller pieces.
Innovation Solution
A manipulating hold down device with a non-ferrous elongated body, embedded magnets, and a cleat handle allows for ergonomic and safe control of materials, securely holding pieces in place and preventing finger contact with moving parts, while enabling precise cuts and operation with various machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operators use hand manipulation to control material, then ease of operation is maintained, but safety deteriorates due to finger contact with moving parts
Solution Approach 1:
The patent introduces a manipulating hold down device as an intermediary tool between the operator's hand and the material. This device features a non-ferrous elongated body with a cleat handle that allows operators to control and hold down material without direct finger contact with the shearing machine's moving parts, thereby eliminating the harmful factor of finger injury while maintaining ease of operation.
2Productivity
If operators work with smaller pieces of stock, then productivity increases, but safety deteriorates due to increased injury risk
Solution Approach 1:
The manipulating hold down device serves as a protective intermediary that enables operators to safely handle smaller pieces of stock. The elongated body provides extended reach, allowing operators to control small materials without their hands being in the danger zone of the shearing machine, thus enabling high-speed processing of small pieces without compromising safety.
3Object-affected harmful factors
If operators discard material to maintain safety distance, then safety is improved, but material waste increases
Solution Approach 1:
The manipulating hold down device acts as an intermediary tool that extends the operator's reach, allowing them to maintain a safe distance from the shearing machine's moving parts while still working with smaller, more valuable pieces of material. The elongated body with cleat handle enables precise control of material positioning without requiring operators to discard usable material, thus reducing waste while maintaining safety.
4Object-affected harmful factors
If OEM guards and hold downs are used, then safety is partially improved, but effectiveness deteriorates due to insufficient material control
Solution Approach 1:
The manipulating hold down device serves as a superior intermediary tool that complements and enhances the functionality of OEM guards and hold downs. While OEM equipment provides basic safety barriers, this device actively enables precise material control and positioning, giving operators direct manipulation capability without compromising safety, thus resolving the insufficiency of material control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances safety and efficiency by allowing operators to handle smaller pieces safely, reducing material waste and preventing injuries, while improving operational precision and expanding the reach of OEM hold downs to accommodate diverse machine types.
Implementation Method 1
A magnet is embedded in the elongated body flush with the under body surface. The magnet's purpose is to hold the elongated body to the flat surface of the work table of a sheet or plate sheer machine.

AI summary
An apparatus for use with various shearing machines for safely and efficiently positioning material to be worked. Magnets which control the material are embedded in a body made of non-magnetic material. Magnets are positioned in the forward end of the apparatus for holding the material being worked while other magnets are positioned in the body of the apparatus for adhering the apparatus to the machine table. A handle is provided for sliding the material into the proper position.
