Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile precooling, in particular to a raw material precooling structure for low-temperature extrusion processing of aluminum profiles. Background Art

[0002] Precooling refers to the process of rapidly cooling an item from an initial temperature of thirty degrees to the required terminal temperature of zero degrees, that is, the cooling before refrigerated transportation and high-temperature refrigeration, as well as the rapid cooling process before rapid freezing are collectively referred to as precooling. Low-temperature extrusion of aluminum profiles is a metal processing technology in which aluminum is shaped through a mold at a lower temperature. The raw material precooling mechanism for low-temperature extrusion of aluminum profiles is a device used to pre-cool aluminum profile raw materials. Its purpose is to reduce the temperature of the aluminum profile raw materials to a low temperature state close to or reaching the extrusion required, thereby reducing the subsequent cooling time and improving the efficiency of the entire production process.

[0003] The existing precooling mechanism usually puts the aluminum material directly into the precooling box when in use, and takes it out after the precooling is completed. This method has low precooling efficiency for the aluminum material, and the aluminum materials piled together will collide with each other, thereby causing damage or deformation on the surface of the aluminum material, affecting the quality of the aluminum material. Before the aluminum material enters the precooling box, the dust on the surface of the aluminum material is not cleaned. After precooling, the dust will be firmly adsorbed on the surface of the aluminum material, affecting the next low-temperature extrusion of the aluminum material. Therefore, in view of the above problems, a raw material precooling structure for low-temperature extrusion processing of aluminum profiles is proposed. Summary of the invention

[0007] Preferably, the dust suction device includes fixed rods symmetrically arranged on both sides of the precooling box body and fixedly connected to the two sides of the precooling box body, one end of the fixed rod away from the precooling box body is fixedly connected to a filter frame, and the side of the filter frame away from the fixed rod is fixedly connected to an exhaust fan passing through the filter frame, and an activated carbon filter is provided on one side of the exhaust fan.

The aluminum is placed between the baffles, and the aluminum passes under the precooling box body for precooling. After precooling, the aluminum is taken out and the next processing can be started;

[0013] 2. In the utility model, the dust collecting device, the fixed rod, the filter frame, the exhaust fan and the activated carbon filter are arranged, so that the aluminum material that is about to enter the precooling box body can be pretreated and the dust on the surface of the aluminum material can be adsorbed.
