Problems solved by technology
At present, the existing muffle furnaces for processing tungsten-molybdenum alloys usually have a single-door structure, and the door needs to be opened for feeding or discharging, so continuous processing cannot be performed, and the degree of automation is low. Semi-finished products are sent to the muffle furnace, not only the production efficiency is low, but also there are flammable and explosive hydrogen leakage and high temperature radiation, and the working environment is poor

The invention relates to an automatic feed mechanism for a muffle furnace special for tungsten-molybdenum alloy. The muffle furnace comprises a support, a furnace body and a control device. Molybdenum boats for holding tungsten-molybdenum alloy are disposed in the furnace body. The automatic feed mechanism comprises a motor, a reducer and a mechanical propulsion device. The motor and the reducer are connected and fixed on the support. The reducer is connected with the mechanical propulsion device. The control device is connected with the motor. The mechanical propulsion device is in contact connection with the molybdenum boats. The motor can drive the mechanical propulsion device to move the molybdenum boats through the reducer. Compared with the prior art, the automatic feed mechanism has the advantages that the molybdenum boat rows are pushed by the motor, the reducer and the mechanical drive device to unidirectionally move for continuous sintering of tungsten-molybdenum alloy; the mechanical automatic feeder is utilized, so that automation level is high, and operating efficiency is high; using is safe and reliable, and work environment is good.
Description
[0001] technical field [0002] The invention relates to a muffle furnace, in particular to an automatic feeding mechanism for a special muffle furnace for tungsten-molybdenum alloys. Background technique [0003] Non-ferrous metals tungsten and molybdenum are refractory metals. The production of tungsten-molybdenum alloys is generally processed by powder metallurgy sintering. The high-temperature processing is usually carried out in a muffle furnace, and hydrogen is used as a protective gas during the sintering process. At present, the existing muffle furnaces for processing tungsten-molybdenum alloys usually have a single-door structure, and the door needs to be opened for feeding or discharging, so continuous processing cannot be performed, and the degree of automation is low. The semi-finished products are sent to the muffle furnace, not only the production efficiency is low, but also there are flammable and explosive hydrogen leakage and high temperature radiation, and ...
