furnace change switch
The furnace change switch is used to quickly switch power between the two furnace bodies of the intermediate frequency smelting furnace. It is designed and manufactured for the water-cooled cable of the smelting furnace to the furnace switch. It replaces manual replacement of water-cooled cables, reduces labor intensity, improves safety and productivity, and reduces safety accidents. Therefore, the furnace change switch of the intermediate frequency furnace is a good accessory accessory for the melting equipment in the foundry workshop.
Structural principle of the medium frequency furnace furnace change switch
The furnace change switch of the intermediate frequency furnace is an electric quick switching switch used in coreless intermediate frequency melting furnaces. Its structure is composed of a stationary block, a movable block, a pressure regulating mechanism, a transmission mechanism, and a frame.
The bolts directly connect the stationary block, the outgoing copper plate and the frame, and the outgoing copper plate is connected to the intermediate frequency power supply or the furnace cable. The contact surfaces of the stationary blocks on both sides and the corresponding movable blocks are inclined, and the movable blocks are The guide plate in the pressure regulating mechanism is connected by springs and bolts. The guide plate is hingedly connected to the screw rod on the worm gear. There are water cooling holes on the movable block. The pressure regulating mechanism has a spring, a guide plate, an adjusting plate and a stroke. Switch, in which the travel switch is fixed to the frame through bolts, the motor in the transmission mechanism drives the worm gear reducer, and the screw rod of the worm gear reducer is hingedly connected to the guide plate in the pressure adjustment mechanism of the movable part; the front and rear of the frame are symmetrical.
Advantages of medium frequency furnace replacement switch
1. The furnace change switch of the intermediate frequency furnace can eliminate the work intensity caused by frequent replacement of the water-cooled cables of the intermediate frequency melting furnace and reduce the labor intensity of workers.
2. The furnace replacement switch of the intermediate frequency furnace increases the safety of replacing water-cooled cables in the intermediate frequency melting furnace.
3. The intermediate frequency furnace change switch can carry the large current of the intermediate frequency power supply and realize bipolar double throw;
4. The furnace change switch of the intermediate frequency furnace can realize mechanical motor or hydraulic transmission, which is precise, strong and durable;
5. All the copper materials of the furnace change switch of the intermediate frequency furnace have been silver-plated or tin-plated, which is not easy to spark; 6. The copper tubes on the copper bar of the furnace change switch of the intermediate frequency furnace are drawn in one piece (not welded), so There is no water leakage.
7. All hydraulic cylinders and metal support columns of the intermediate frequency furnace change switch are made of 304L stainless steel and degaussed to prevent heat generation.
The furnace changing switch of the intermediate frequency furnace is easy to operate and use, shortening the furnace switching time, improving efficiency, reducing the labor intensity of workers, and can easily realize the switching of the insulation furnace body and the melting furnace by the intermediate frequency power supply, and the intermediate frequency melting The furnace is very practical on site.
Two induction furnaces, one works and the other is standby. The switch is used tochange the furnace body. It does not need to remove the water-cooled cable, which is more efficient and convenient.
