Welding of drill bits for prospecting, such as welding of a sub-drill and a claw bit. 3. Composite welding of metal materials such as brass, copper, stainless steel, etc. Many companies are still using the old-fashioned electronic tube equipment or thyristor intermediate frequency in the 1960s and 1970s. This type of machine has disadvantages such as high power consumption, high maintenance cost, and troublesome operation and use. Some manufacturers use flame and coal furnace for metal brazing and diathermy forging. This process has the disadvantages of high cost, thick surface oxide scale, difficult to control heating temperature, and difficult to guarantee the quality of workpiece.

Energy saving and environmental protection high frequency quenching equipment The utility and operation method of numerical control high frequency quenching equipment: (1) The utility of Kehua numerical control high frequency quenching equipment Kehua numerical control high frequency quenching equipment is mostly used for surface quenching of industrial metal parts, which is to make the surface of the workpiece produce certain A metal heat treatment method that induces current, rapidly heats the surface of the part, and then rapidly quenches it. Induction heating equipment, that is, equipment for induction heating of workpieces for surface quenching. The principle of induction heating: the workpiece is placed in the inductor, and the inductor is generally a hollow copper tube inputting intermediate frequency or high frequency alternating current (1000-300000Hz or higher). The alternating magnetic field generates an induced current of the same frequency in the workpiece. The distribution of this induced current in the workpiece is uneven, it is strong on the surface, but weak in the interior, and it is close to 0 in the center. This skin effect is used. , the surface of the workpiece can be heated rapidly, the surface temperature rises to 800-1000oC in a few seconds, and the temperature of the core is very small. (2) The operation mode of the high-frequency quenching equipment The workpiece is placed in an inductor wound with a hollow copper tube, and after passing in an intermediate frequency or high-frequency alternating current, an induced current of the same frequency is formed on the surface of the workpiece, and the surface or part of the part is Rapid heating (the temperature can be increased to 800-1000°C in a few seconds, and the heart is still close to room temperature), and immediately after a few seconds, spray (immersion) water cooling (or spray immersion oil cooling) to complete the immersion work, so that the surface or part of the workpiece is meet the corresponding hardness requirements. (3) Compared with ordinary heating and quenching, the application of induction heating surface quenching has the following characteristics: 1. Kehua heating speed is extremely fast, which can expand the transformation temperature range of A body and shorten the transformation time. 2. After quenching, the surface layer of the workpiece can obtain extremely fine cryptocrystalline martensite, and the hardness is slightly higher (2-3HRC). Lower brittleness and higher fatigue strength. 3. The workpieces treated by this process are not easy to be oxidized and decarburized, and even some workpieces can be directly assembled and used after treatment. 4. The hardened layer is deep, easy to control and operate, easy to realize mechanization and automation. Energy-saving and environmentally friendly high-frequency quenching equipment is used in many aspects of the production of auto parts, as well as some hardware processing tools such as vices, hammers, strong pliers and other tools, and many metal daily necessities can also be produced.
