Device for conveniently heating aluminum alloy blank materials

Abstract

The invention discloses a device for conveniently heating aluminum alloy blank materials. The device comprises a furnace body, an air blower, an exhaust fan, a supporting plate and a weight-bearing mechanism; the left side and the right side of the furnace body are respectively provided with openings forming a discharging port and a feeding port; the air blower and the exhaust fan are both communicated with the interior of the furnace body; communication channels of the air blower and the exhaust fan with the furnace body are respectively positioned at the top of the left end and the right end of the furnace body. The supporting plate passes through the furnace body, and the left end and the right end of the supporting plate are respectively arranged at the feeding port and the discharging port of the furnace body; the weight-bearing mechanism comprises a plurality of supporting rollers arranged side by side in the furnace body and used for supporting the supporting plate. The device has the advantages of simple integral structure, convenient implementation and low cost; when in application, the air blower is adopted to add hot air into the furnace body for heating the interior of the furnace body, and the exhaust fan is adopted for exhausting air, so that the hot air in the furnace body is convenient to circulate, the heating difference of the aluminum alloy blank materials heated by the furnace body is reduced, and thus the cracking and scrapping probability of the blank materials can be reduced.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a device for heating aluminum alloy billets. Background technique [0002] Many existing mechanical spare parts are made of aluminum alloy. In order to improve the utilization rate of aluminum alloy blanks and reduce production costs, people often use forging and pressing when manufacturing aluminum alloy spare parts. Among them, the aluminum alloy billet needs to be heated before forging. Nowadays, people often place multiple pieces of aluminum alloy billet in the furnace body of the medium-temperature box-type electric furnace, and then the electric heating element of the medium-temperature box-type electric furnace generates heat to heat the billet in the furnace body. The heating method of the medium-temperature box-type electric furnace is radiation heat transfer. Because the aluminum alloy billet does not have high requirements on the heating temperature, the heat transfe...

Problems solved by technology

Among them, the aluminum alloy billet needs to be heated before forging. Nowadays, people often place multiple pieces of aluminum alloy billet in the furnace body of the medium-temperature box-type electric furnace, and then the electric heating element of the medium-temperature box-type electric furnace generates heat to heat the billet in the furnace body. The heating method of the medium-temperature box-type electric furnace is radiation heat transfer. Because the aluminum alloy billet does not have high requirements on the heating temperature, the heat transfer effect is not good when using radiation heat transfer. The temperature of the blanks is low, and it is easy to cause some blanks in the same furnace to be over-burned and scrapped due to overheating, and some blanks are cracked due to insufficient heating.
