大部分的鋁卷生產廠家采取積極的熱變形擠壓成型方法通過特定的(錐死,死,死)來獲得所需的橫截面的形狀鋁,由于外部因素的影響點顏色鋁輥在生產過程中會拖黑的缺陷,渣,所以如何解決這個問題,減少廢料,提高收益率?這里有三種方法:
Most aluminum coil manufacturers adopt active hot deformation extrusion method to obtain the required cross-section shape of aluminum through specific (cone dead, dead, dead). Due to the influence of external factors, the spot color aluminum roll will drag black defects and slag in the production process, so how to solve this problem, reduce waste and improve the yield? Here are three methods:
1. 生產過程控制
1. Production process control
切割彩涂鋁輥,用風管清理彩涂鋁輥上的灰塵,減少灰塵的帶入,減少黑、渣的來源;
Cut the color coated aluminum roller, use the air pipe to clean the dust on the color coated aluminum roller, reduce the introduction of dust, reduce the source of black and slag;
殘余厚度要保持足夠,過薄的殘余壓力會導致彩涂鋁盤管在卷尾處卷入型材,造成黑、渣;
The residual thickness should be enough, too thin residual pressure will cause the color coated aluminum coil to be drawn into the profile at the end of the coil, resulting in black and slag;
擠出速度要有效控制,特別是擠出端部要減速,防止湍流卷入表面雜質。
The extrusion speed should be controlled effectively, especially the extrusion end should be decelerated to prevent turbulence from getting involved in the surface impurities.
對生產的各個階段進行清理;
Clean up all stages of production;
2. 設備設備調整
2. Equipment adjustment
如果擠壓棒不在中間,擠壓棒運動磨損材料膽囊,會造成材料膽囊腹部變形等缺陷;模座中心,上、下、左、右向中心,嚴禁移動模座進行生產,上下錯誤,要聯系機修進行維護;壓實餅的大小應定期檢測和更換。壓實后的卷邊餅也會產生發黑、夾渣等報廢現象。材料膽囊使用很長一段時間,如出現變形,也會導致批量報廢,報廢生產很多,需要注意,新材料膽囊必須清除污垢的膀胱和膀胱拋光機安裝之前。
If the extrusion bar is not in the middle, the movement of the extrusion bar will wear the gallbladder of the material, which will cause the abdominal deformation of the gallbladder of the material and other defects; the center of the mold base, up, down, left and right, is strictly prohibited to move the mold base for production, and the up and down errors should be contacted with the machine for maintenance; the size of the compaction cake should be regularly inspected and replaced. After compaction, the curling cake will also produce blackening, slag inclusion and other scrap phenomena. Material gallbladder used for a long time, if there is deformation, it will also lead to batch scrapping, scrapping a lot of production, it needs to be noted that the new material gallbladder must be cleaned of dirt before the installation of bladder and bladder polishing machine.
3.調整模具設計和生產計劃
3. Adjust mold design and production plan
對于平面模具,如有必要,應安裝導流板進行導流,以縮小進料口,夾緊死區。材料孔必須完全被模具分流孔包圍,對每一套模具進行監控比較,如分流孔太大的現象,不能在機器上生產,要轉到機器上生產。
For flat die, if necessary, guide plate shall be installed to guide the flow, so as to reduce the feed port and clamp the dead zone. The material hole must be completely surrounded by the mold shunting hole, and each set of mold shall be monitored and compared. If the shunting hole is too large to be produced on the machine, it shall be transferred to the machine for production.
