High-frequency heating furnace

Abstract

The invention discloses a high-frequency heating furnace, and belongs to the technical field of metal heating furnaces. In the prior art, feeding and discharging of a high-frequency heating furnace are not convenient. Based on the following scheme, the high-frequency heating furnace comprises an upper heating furnace cavity and a lower high-frequency control cabinet. A material channel obliquely penetrates the heating furnace cavity. One end of the material channel is connected with a charging hopper, and the other end of the material channel is connected with an unloading hopper. The sectionof the material channel is semicircular, a heat-resisting material layer on the inner layer and a heat preservation layer on the outer layer are included, an electromagnetic induction coil is arrangedoutside the heat preservation layer, and a temperature sensor is further arranged in the material channel. The electromagnetic induction coil and the temperature sensor are both connected to the high-frequency control cabinet. The high-frequency control cabinet is internally provided with a controller, and the controller adjusts the frequency of a high-frequency power source according to parameters of the temperature sensor. A heat dissipation fan is arranged at one end of the heating furnace cavity. The high-frequency heating furnace can conduct rapid feeding and discharging, and meets the requirement of line production.

Description

technical field [0001] The invention belongs to the technical field of heating furnaces, and in particular relates to a high-frequency heating furnace. Background technique [0002] In a material-saving processing technology of the ball cage cage, the bar is cut and heated, and then upsetting, punching, and reaming are completed to complete the blank processing; in the above process, the short bar after cutting is not large in size. It can be heated by ultra-sonic audio, and the ultra-sonic heating is rapid, and it can keep up with the processing rhythm of the previous process and the subsequent process, and realize the flow operation; however, in the prior art, there is no high-frequency heating furnace with fast feeding and discharging , It can meet the processing speed of cutting-heating-upsetting-punching-reaming. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-frequency heating furnace capable of fas...
