How does the high frequency heating machine weld the turning tool?

Many customers and friends do not understand the operation of welding turning tools using high-frequency heating machines. According to this situation, the engineers of Wenzhou Rui'ao Technology Co., Ltd. have conducted in-depth analysis of skills, which can help everyone better operate and understand.

The main contents can be divided into the following points:

1. Summary of high-frequency heating machine welding tool problems:

1. Preparation work: prepare the workpiece and corresponding auxiliary materials, brazing material, use 105﹟ manganese brass and borax

2. Workpiece processing: The design of the kerf, the cleaning of the blade and the kerf, the kerf equipment should be reasonable, and the parent material must be treated and cleaned.

3. Operation steps

The first step: Use a high-frequency heating machine to heat the workpiece to be brazed to about 650 degrees Celsius.

Step 2: Fix the cutter head that needs to be welded and burn it to the welding temperature.

Step 3: Lay the knife base flat, and after it burns red, sprinkle a little borax on the welding part, use a copper electrode to evenly weld a thin layer of copper on the knife base, then sprinkle a little borax and put on the knife head to heat, wait for the knife head After burning red, fill the gap with a welding rod dipped in borax. Note: The temperature should not be too high, and the welding place should be uniform.

The fourth step: heat preservation tempering and low temperature tempering. Put it into ash to cool or cool it in lime tank, and it can also be put into 350~380? furnace for low temperature tempering for 6~8 hours.

4. Pay attention to the operation details to ensure the quality of the welded products.

2. Analysis of welding tool skills:

1. When processing the workpiece, pay attention to removing the oxide film and oil stains on the contact surface of the base metal, so as to facilitate the capillary tube to play a role after the solder is melted and increase the wettability and capillary fluidity of the solder. It is very important to remove oil stains and excessively thick oxide film, and ensure the interface assembly gap. The gap is generally required to be between 0.01 and 0.1 mm.

2. Attention should be paid to the preparation steps: copper alone is not enough, and a deoxidizer is necessary, and the most commonly used is rosin powder.

3. During the welding process, it should be noted that the less the amount of copper, the better, the copper electrode is dipped in appropriate amount of borax and burned at the welding place between the cutter head and the cutter bar.

4. In addition, there must be a certain level of operation. When the alloy hair turns red, it must be aligned with the substrate immediately, not only to be fast, but also to be accurate. Because if it's not right, it's not good to do it a second time. Therefore, there are also requirements for our high-frequency brazing technology. Because I have seen a lot of welding ordinary turning tools, the alloy head always falls off when working. Later, an old master welder re-welded it again, and the effect was just right. When the alloy hair turns red, it has to be aligned with the base immediately.

3. Summary:

The above is the experience summed up by Wenzhou Rui'ao Technology Co., Ltd. in the field of high-frequency brazing for more than ten years. It can be implemented in strict accordance with the above steps, and we must pay attention to the details in the technical analysis. If there is anything unclear, you can also consult the Tongcheng technical department at any time.
