摘要 伴隨著我國加快經(jīng)濟體制改革步伐并順利加入 WTO 中央空調(diào)行業(yè) 及其他各行各業(yè)都面臨史無前例的挑戰(zhàn)和機遇 家用中央空調(diào)應用范圍 為 80 800m2 住宅 但是隨著我國房地產(chǎn)行業(yè)的突飛猛進 100m2 以上的 住宅在如今樓盤建設中比例越來越大 這就直接為中央空調(diào)提供了晉級 空間 空調(diào)核心的制冷部件是冷凝管 制冷裝置的重要原材料就是冷凝管 是制冷劑的運輸通道 就現(xiàn)在看來冷凝管主要由彎管機生產(chǎn) 全自動盤 料彎管機彎曲裝置是彎管機不可缺少的一部分 由彎曲模 夾緊模 托 架 夾緊油缸 彎曲油缸 托架油缸 彎曲齒條 軸承座 彎曲齒輪等 構(gòu)成 銅管經(jīng)過導向套筒從彎曲模和夾緊模之間穿入全自動彎管機主機 的芯軸桿上 然后夾緊模將銅管夾緊在兩模之間 同時托架上升托住銅 管 彎曲裝置向前翻轉(zhuǎn)作 180 彎曲 將銅管彎制成 U 型管 本設計對彎管機盤管彎曲裝置進行了總體結(jié)構(gòu) 彎曲模 夾緊模的 設計 對齒輪齒條進行了計算與校核 對軸承進行了選擇與校核 對軸 進行了設計與校核 并選取了動力系統(tǒng) 論述了彎管機彎曲裝置的調(diào)整 故障及其處理方法 關于自動彎管彎管機底部凹模 模角一般為 86 86 在行程的底 部 集約應具有比之間的間隙的材料厚度略大 為了提高成形角度 因 為一個底模彎曲大 約 4 倍 降低的彎曲半徑范圍通常導致回彈應力 沖壓具有底部彎曲模具彎曲是相同的 只是把打孔處理的前端成為需要 的彎曲半徑 而密集的間隙小于該材料在沖程的底部的厚度 由于施加 足夠的壓力彎曲 約 10 倍 力沖前接觸材料 基本上避免了回彈 為

opportunities Home central air conditioning is suitable for 80 800mm2 residential as China s housing industry 100mm2 or more new residential housing in the proportion is growing This provides central air conditioning provides a huge space for development In the air conditioned interior plays an important cooling components are reusable condenser Condenser refrigeration apparatus is an important raw material is a refrigerant channel Condenser tube bending machine depends mainly on the production automatic plate feeding tube bender bending device is a part of the bending mold mold clamp bracket clamp cylinder bending cylinders cylinder bracket bend the rack bearing bent gear and other accessories Brass through the guide sleeve and clamping mold from bending mode between automatic bending machine host penetration mandrel rod and then the brass clamping mold mold clamping between the two while boosting the bracket up brass flip forward bending device for 180 bend bend the copper tube into the U tube The design of the coil for pipe bender bending device for the overall structure of the bending mold mold clamping design rack and pinion were calculated and checked A selection of the bearing and checked The shaft is designed and checked And select the power system discusses bender bending device adjusting the fault and its treatment About the automatic bending pipe bender a bottom concave die die Angle generally is 86 86 In the bottom of the stroke intensive should have a slightly larger than the material thickness of the gap between To improve the forming Angle because a bottom die bending the large tonnage of bends about 4 times reduced the bending radius range usually cause the springback stress Stamping bending with a bottom bending die are the same just put the front end of the punch processing became the bending radius of the need and intensive clearance is less than the thickness of the material at the bottom of the stroke Due to exert enough pressure bends about 10 times force punch front contact material basically to avoid the springback In order to select the minimum tonnage specifications the best is greater than the material thickness of the bend radius to plan and as far as possible by free bending method When bending radius is bigger often do not affect the quality of the pieces and its use in the future Precision bending precision demand is a need careful consideration it is this factor determines the you need to consider a CNC pipe bending machine or manual pipe bender If bending accuracy 1 and cannot be changed you must focus on CNC machine CNC pipe bender slider repeat accuracy is 0 0004 inches forming a precise Angle that should be used in the precision and good mould Manual pipe bender slider repeat precision of 0 002 inches and under the condition of using appropriate mould generally produces the deviation of plus or minus 2 3 In addition CNC pipe bender to prepare for loading die quickly when you need to bend many small batch parts this is a no doubt consider the reasons Die even if you have a shelf full of die don t think that these mould is suitable for the new machine Must be checked every mould wear and method is a measure of the length of the punch front end to shoulder length between the shoulder and concave die For conventional mold deviation should be per foot around 0 001 inches and the deviation is not more than plus or minus the total length of 0 005 inches As for fine grinding mould per foot accuracy should be 0 0004 inches the total accuracy may not be greater than 0 002 inches Best to fine grinding mould used for CNC pipe bender conventional mold for manual pipe bender Indeed we are often made to buy only the new pipe bender and don t buy the right mold to match error Bending side people often ignored one factor is the material in front of the tube bending machine bending length Assumptions along a 5 x 10 feet 10 the gauge of low carbon steel plate bending 90 7 5 tons of pressure pipe bender probably will be charged on the steel top up and the operator must be geared up for the 280 pound straight down Make the parts may need several strong workers even a crane Bending the pipe bending machine operator often need long side parts but don t realize how much they work hard Now there is a retainer device suitable for the workshop engaged in this work the device can be modified according to the needs of new and old machine Using the pipe bending machine mould device forming long side parts only one operator Keywords bending gear bending rack flexural modulus
