Heating mechanism for forging and pressing aluminum alloy billets

Abstract

The invention discloses a heating mechanism for forging and pressing aluminum alloy billets. The heating mechanism comprises a furnace body, electric heating elements, fans, a support plate and a bearing mechanism, wherein the left and right sides of the furnace body are respectively opened to form a discharge port and a feed port; the electric heating elements are arranged in the furnace body; and a rotating shaft of each fan penetrates through the top of the furnace body, and blades of the fan are arranged in the furnace body. The support plate penetrates through the furnace body, and the left and right ends of the support plate are respectively arranged in the feed port and the discharge port of the furnace body; and the bearing mechanism comprises a plurality of support rollers arranged in the furnace body in parallel and used for supporting the support plate. The heating mechanism has the advantages of simple integral structure, convenience for realization and low cost, and can reduce the heating difference of various aluminum alloy billets heated by the furnace body under the effect of the fans so as to reduce the rupture and waste probability of the billets in application.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a heating mechanism for a blank before forging an aluminum alloy. 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 temperat...

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.
