Swage Anvil Lateral Positioning for Saw Blade Tooth Support

Solution Overview

Problem

Conventional saw blade swaging processes require significant setup time and risk damage due to the iterative adjustment of the anvil position, leading to increased manufacturing costs and potential tooth damage.

Innovation Solution

A swage anvil with a coupling portion allowing lateral positioning and a tooth contact face mirroring the angle of the saw blade's top rear surface, enabling single-axis translation for adequate support during swaging, reducing setup time and minimizing damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the anvil position is adjusted iteratively to provide adequate contact with the tooth back portion, then the support accuracy is improved, but the setup time increases significantly

Engineering Contradiction:

Improveanvil contact accuracyVSAvoidsetup time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The anvil is pre-positioned at a predetermined location within the swage head before the swaging operation begins. This preliminary positioning eliminates the need for iterative adjustments during setup, as the anvil is already in the correct position to contact the tooth back portion when the saw blade is inserted.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The swage head structure itself provides the positioning function through its predetermined geometry and features. The anvil is integrated into the swage head design with built-in positioning mechanisms, allowing the system to self-position without requiring external manual adjustment operations.

Inventive Principle:

Principle #25Self-service

2Loss of time

If the anvil position is not properly adjusted, then the setup time is reduced, but the tooth may be damaged during swaging

Engineering Contradiction:

Improvesetup timeVSAvoidtooth integrity

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The anvil is pre-positioned at a predetermined location within the swage head before the swaging operation begins. This preliminary positioning eliminates the need for iterative adjustments during setup, as the anvil is already in the correct position to contact the tooth back portion when the saw blade is inserted.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The predetermined anvil position ensures that the tooth back portion is already supported by the anvil before the eccentric die applies pressure during swaging. This pre-positioning acts as a protective measure that prevents tooth damage by ensuring proper support is in place before the forceful swaging action occurs.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Manufacturing precision

If multiple adjustment operations are performed to position the anvil and swage head, then the contact precision is improved, but the device complexity increases

Engineering Contradiction:

Improvecontact precisionVSAvoidadjustment mechanism complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The anvil is pre-positioned at a predetermined location within the swage head before the swaging operation begins. This preliminary positioning eliminates the need for iterative adjustments during setup, as the anvil is already in the correct position to contact the tooth back portion when the saw blade is inserted.

AI summary

A swage anvil includes a coupling portion that, when mated with a corresponding die of a swaging device, allows lateral positioning of the swage anvil (i.e., substantially parallel to a long axis of the saw blade) relative to the long axis of the saw blade. The swage anvil also includes a tooth contact face that substantially mirrors an angle of the back portion of each tooth of the saw blade. As such, after a manufacturer inserts the swage anvil into the swage device and laterally translates the swage anvil, the tooth contact face abuts the back portion of the saw blade tooth to support the tooth during a swaging procedure. With the aforementioned configuration of the swage anvil, translation of the swage anvil along a single axis provides support to the back portion of the saw blade tooth along two axes. As such, use of the swage anvil decreases the set-up time required in conventional swaging devices.
