Description

Technical Field

[0001] This utility model relates to the field of metal material processing technology, specifically a technical device for removing impurities generated during the processing of aluminum alloy extruded profiles. Background Technology

[0002] Aluminum profiles or tubes are usually obtained through hot extrusion. During the hot extrusion process, some impurities will be generated on the surface of the aluminum material, which appear as hard particles or burrs. The reasons for this are as follows: 1. Some impurities in the original cast rod, such as oil, dust, aluminum shavings, etc., are released during the extrusion process, forming granular burrs on the surface of the aluminum material; 2. Aluminum sticks to the working edge of the extrusion die, and the sticky aluminum is gradually carried out by the extruded aluminum material, forming small particles that adhere to the surface of the aluminum material.

[0003] Particles and burrs on the surface of aluminum affect its surface quality. Untreated aluminum is repeatedly rubbed on the conveyor and sawing tables, causing fine scratches on the surface. Secondly, if further surface treatment is required, the aluminum surface still needs grinding, increasing workload. Thirdly, impurities adhering to the aluminum surface become harder and more firmly attached after aging, easily scratching the hands of inspectors. Therefore, removing particles and burrs from the aluminum surface before sawing is essential. Typically, production workers use a cloth or foam dishcloth to wipe the surface of the aluminum profiles before sawing to length, removing most of the particles and burrs. However, manual labor is labor-intensive and inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide a technical device for removing process-related impurities from the surface of extruded aluminum alloy profiles. The device is installed at the end of the sawing feed roller table and uses a brush roller that rotates and scrapes the upper and lower end faces of the aluminum profile to clean the particles and burrs on the surface of the aluminum material, thereby improving the surface quality of the aluminum material and saving the labor cost of manual processing.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A technical device for removing process-related impurities from the surface of aluminum alloy extruded profiles includes support columns installed on both sides of the end of the sawing feed roller table, a roller shaft installed between the two support columns, and a brush roller connected to the middle of the roller shaft via a bearing. The brush roller is densely covered with nylon bristles.

[0007] The high-speed rotating brush roller removes impurities and burrs from the surface of aluminum materials, increasing efficiency by dozens of times compared to manual wiping, and eliminating the need to stop the machine to transfer materials. This device can be easily added to existing production lines at low cost, can be installed immediately upon use, and is convenient to maintain.

[0008] One brush roller is respectively installed on the upper and lower surfaces of the aluminum material. The end of the upper brush roller is connected to the end of the lower brush roller through a transmission mechanism B, and the end of the lower brush roller is also connected to the motor shaft below through a transmission mechanism A. The transmission mechanism can be a chain and gear drive or a pulley and belt drive. The motor can also be a variable frequency motor to adjust the motor speed and achieve different scraping speeds.

[0009] The roller shaft is connected to the support column via a positioning ring. The positioning ring is sleeved on the outer diameter of the support column, and a threaded hole is provided on the positioning ring. A set bolt is screwed into the threaded hole for positioning.

[0010] The positioning ring can move freely up and down. When the positioning ring reaches the set position, tightening the set bolt to press against the support column will position the positioning ring. Different brush roller heights are used for aluminum materials of different heights; however, it should be noted that if the transmission mechanism does not have a belt or chain tensioning device, belts and chains of different lengths need to be used when adjusting different brush roller heights.

[0011] Advantages of utility models

[0012] 1. This utility model has a brush roller installed at the end of the sawing feed roller table. The brush roller continuously rotates and scrapes the upper and lower end faces of the aluminum profile to clean the accompanying impurities, particles and burrs on the surface of the aluminum material, thereby improving the surface quality of the aluminum material and saving the labor cost of manual processing.

[0013] 2. This utility model can be installed on existing production lines, which is inexpensive, can be installed as needed, and is easy to maintain.

[0014] 3. The height of this utility model is adjustable, making it suitable for aluminum materials of different sizes and highly adaptable. Attached Figure Description
