Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile manufacturing, in particular to an aluminum profile aging furnace. Background Art

[0002] During the processing of aluminum profiles, it is necessary to use an aging furnace for preheating treatment. The aluminum profile aging furnace is a special equipment used to eliminate the preheating of aluminum alloy materials after initial processing. After the aluminum profile is extruded, it needs to be aged to reduce the stress concentration of the aluminum alloy material, stabilize the structure and size, reduce the deformation of the aluminum alloy material, and improve the mechanical properties of the aluminum alloy material.

[0003] The structure of the aluminum profile aging furnace is similar to that of a general oven. The aging furnace is mainly composed of a furnace door device, an insulation furnace body, a hot air circulation system, a heating system, a trolley device and an electronic control system. The heating system uses a gas burner and the fuel is compressed natural gas. In order to ensure the uniformity of the furnace temperature, a centrifugal circulation fan is installed on the top of the furnace body, and the hot air circulation guide system in the furnace is reasonably configured to make the air flow in the furnace evenly distributed to ensure the heating quality and heating speed. The full metal structure is welded with two layers of steel plates inside and outside the furnace body, and the middle is evenly filled with aluminum silicate refractory fiber for insulation to reduce the temperature rise of the furnace wall. The furnace door of the existing aging furnace adopts an electric lifting furnace door. However, there will be a gap between the furnace door and the furnace body after it is lowered, resulting in poor sealing of the furnace door, which in turn causes heat loss and affects the quality of the aluminum profile.

[0046] Working principle: When the aluminum profile is subjected to aging strengthening, the lifting motor is first started, and the lifting motor drives the gate 2 to rise. At the same time, the counterweight block 42 connected to the other end of the traction rope 43 is lowered to ensure that the gate 2 can rise smoothly. Then the power trolley 7 pushes the material frame for placing the aluminum profile into the furnace body 1, puts down the gate 2, and then starts the pressing component 5, so that the cylinder pushes the locking door frame 52 to flip inward, so that the pressing plates 522 at both ends of the locking door frame 52 tightly press and buckle the gate 2 to increase the sealing of the gate 2. When the aluminum profile completes the aging treatment, the gate 2 is opened again, and the aluminum profile in the accommodating cavity 11 is pulled out of the furnace body 1 to complete the aging treatment of the aluminum profile.
