Continuous hot-pressing furnace

Abstract

The invention discloses a continuous hot-pressing furnace which comprises a furnace body and a press machine. A conveying channel used for allowing charge boats to pass is arranged in the furnace body, wherein door valves are arranged at the two ends of the conveying channel. A heating element is arranged at the position, located on the outer side of the conveying channel, in the furnace body. A press head of the press machine stretches into the furnace body. When the charge boats pass through the position below the press head, the press head moves downwards to carry out press molding on heated materials in the charge boats. According to the continuous hot-pressing furnace, a tunnel type hearth structure is adopted, and the charge boats containing to-be-pressed products pass through a hearth (namely, the conveying channel) in an array for heating; when the charge boats reach the position of the press machine for pressurization, the requirement temperature is achieved already, and thenfast pressing can be achieved; and the products are free of oxidization under atmosphere protection in the whole process, the full-automatic feeding and discharging manner is adopted, time and manpower are saved, meanwhile, energy consumption is reduced, and the product quality and the production efficiency are greatly improved.

Description

Technical field [0001] The invention relates to the field of powder metallurgy forming equipment, in particular to a push-boat type continuous high-efficiency hot pressing furnace. Background technique [0002] There are two types of traditional hot pressing process equipment: the first is to put a single workpiece into a special hot pressing equipment, raise the temperature of the workpiece to a set value and then pressurize, and turn on the furnace after the furnace temperature has cooled. The door manually takes out the workpiece; the second is to add a high-frequency heating device to the press to quickly heat a single workpiece to the required temperature and apply pressure. Among them, the disadvantage of the first hot pressing process is that the heating and cooling time is very long, and the efficiency is very low; the disadvantage of the second hot pressing process is that there is no atmosphere protection when the workpiece is heated, and it is easy to oxidize when expo...

Problems solved by technology

Among them, the disadvantage of the first hot-pressing process is that the heating and cooling time is very long, and the efficiency is very low; the disadvantage of the second hot-pressing process is that there is no atmosphere protection when the workpiece is heated, and it is easy to oxidize when exposed to air, and the efficiency is not high.
