Saw Blade Tooth Stellitizing and Tempering Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current saw blade machining devices require separate processes for stellitizing and tempering, necessitating re-clamping and realignment, which is time-consuming and prone to inaccuracies, leading to potential distortion or breakage of saw teeth.
Innovation Solution
A device that integrates stellitizing and tempering processes in a single clamping setup, using a feed device to position saw teeth and a shifting starting device to facilitate both processes without re-clamping, with options for manual or controlled movement and adjustable induction loops for precise stellite application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate processes are used for stellitizing and tempering, then each process can be performed with dedicated equipment, but re-clamping and realignment are required which increases time consumption and risk of inaccuracies
Solution Approach 1:
The patent combines two separate machining processes (stellitizing and tempering) into a single integrated device. The saw blade remains clamped in the same device throughout both operations, eliminating the need for re-clamping and realignment between processes. This merging of functions directly resolves the contradiction by maintaining reliability while reducing time loss.
Solution Approach 2:
The machining device is designed to perform multiple functions: it can both stellitize and temper saw teeth. The device includes a feed device for positioning saw teeth, a starting device for tempering that can be shifted between rest and working positions, and appropriate heating means for both processes. This multi-functionality allows the same clamping setup to serve both operations.
2Productivity
If re-clamping is performed between stellitizing and tempering, then the saw blade can be processed in separate jobs, but inaccuracies can occur leading to unusable saw blades
Solution Approach 1:
By merging stellitizing and tempering into one continuous operation within the same clamping device, the patent eliminates the intermediate handling step that causes alignment inaccuracies. The saw blade remains securely held in the same position throughout both processes, ensuring manufacturing precision is maintained while productivity is improved.
Solution Approach 2:
The saw blade is clamped and positioned once before both operations begin. The feed device is configured to accurately position each saw tooth for both stellitizing and tempering from this single initial setup. This preliminary positioning action prevents subsequent alignment errors that would otherwise require re-clamping.
3Ease of operation
If the starting device is manually shifted, then operation flexibility is maintained, but automation level is reduced
Solution Approach 1:
The starting device is designed with dynamic characteristics, allowing it to be shifted between rest and working positions. The patent provides flexibility in control methodology: the shifting can be performed manually for operational flexibility, or a controllable drive can be used to increase automation. This dynamic design accommodates different operational requirements and automation levels.

AI summary
The apparatus has a clamping device for clamping and guiding a saw blade to be processed. A computerized numerical controllable feed device displaces a predetermined saw tooth of the saw blade in a predetermined processing position. A stellite device (10) includes a wire supply device (12) for supplying welding wires (14), and a welding torch (16). A high-frequency starting device supplies heat to the predetermined saw tooth that is displaced in the processing position, where the starting device is displaceable from a rest position into a starting position and vice versa. An independent claim is also included for a method for processing of saw teeth of saw blades.
