High frequency auto brazing machine for core drill bits diameter from 20-550mm
This equipment is a kind of automatic brazing machine, who welded together with diamond segments and core drill bits body by high frequency welding. The device is mainly suitable for welding core drill bits diameter 70-600mm.
Functions and Features
1. Pneumatic push tooth, automatic alarm display for running the fault.
2. The parameters of related R/F-segment, L/T-segment and saw, welding time, welding gear, cooling time, skip welding, can be adjusted according to actual needs.
3. High degree of automation, high positioning accuracy, automatically sending segment, automatically feeding solder wire, automatic brushing flux.
Working process
The process of electric induction brazing is shown and explained while watching the machine in action that automates parts of this process, with the aid of manually pushing buttons at the right time and manually adding necessary materials for the brazing of the diamond blade to be completed. Diamond blades are used for cutting materials that are especially tough to cut through, such as stone, concrete or asphalt. Segments eventually wear out with heavy use and then need to be replaced to make the blade effective again for cutting through tough materials. This video shows the process of soldering new diamond segments around the outside edge of a large blade.
After stripping it, will clean it with an air sander, it is important that the surface is clean when soldering so all will bond to it, now it will go through the heat cycle, 24 seconds, segment gets red, not it is going through the cooling cycle, the indexer, clamp the blade, then it will go through the cycle again, add flux, solder won’t stick without the flux, placing segment, heating both sides at the same time, put less heat on the blade, good consistency for the segment, minimal segment loss.
