常州良旭車輛配件有限公司，地處江南名城常州市，位于常州國家高新技術(shù)開發(fā)區(qū)，與上海、南京等距相望，地理位置優(yōu)越，交通便捷，距常州機(jī)場、常州港口、滬寧高速公路均不到15公里，公司占地40余畝，擁有廠房30000多平方米，從1995年開始研發(fā)制造彎管設(shè)備，自2000年起專注于加工生產(chǎn)“散熱器出水管”等管類產(chǎn)品，2006年初成為中國重汽集團(tuán)管類產(chǎn)品的主要供應(yīng)商。目前主要生產(chǎn)：HOWO、A7、T7、C7等系列的排氣管、中冷器進(jìn)出氣管、散熱器出水管、擋泥板支架、卡箍等400多種獨(dú)家供貨產(chǎn)品。
常州良旭是高新技術(shù)企業(yè)，現(xiàn)有發(fā)明專利、實(shí)用新型專利、外觀設(shè)計專利30多項(xiàng)、獨(dú)家技術(shù)20多種，以一流的彎管技術(shù)得到了國內(nèi)外知名企業(yè)的認(rèn)可。
為確保產(chǎn)品質(zhì)量，公司從“原料采購”到“產(chǎn)品發(fā)交”道道把關(guān)，原材料進(jìn)場用光譜儀、拉力試驗(yàn)機(jī)做化學(xué)成分分析及物理性能試驗(yàn)，剔除不合格材料；生產(chǎn)過程用關(guān)節(jié)臂測量儀保證合理公差范圍，氣密性檢測儀檢測焊接質(zhì)量和管端連接結(jié)構(gòu)的氣密性、影像測量儀來分析特殊特性質(zhì)量問題；管件表面加工后，抽檢部分產(chǎn)品進(jìn)行鹽霧試驗(yàn)，確保外觀質(zhì)量。
全過程的質(zhì)量控制，使各類產(chǎn)品無論是外觀品質(zhì)，還是性能質(zhì)量都能得到保證，在汽車行業(yè)一直遙遙領(lǐng)先，連續(xù)五年被中國重汽評為合格供應(yīng)商并取得獨(dú)家供貨權(quán)力。
公司擁有國際最先進(jìn)的全自動數(shù)控彎管設(shè)備，彎曲半徑最小為0.8D，與通常彎曲半徑為1.5D相比，給整車安裝保留了更多的空間，避免了干擾點(diǎn)；減薄率≤20%，如2mm厚的管子彎曲后還＞1.6mm；采用伺服電機(jī)控制，與以往的液壓系統(tǒng)控制相比，控制更為精密，自動化程度更高，所有的調(diào)試、潤滑等工作都由電腦控制完成，提高工人安全性，并可遠(yuǎn)程控制。
“切管”采用機(jī)器人三維激光切割機(jī)——與傳統(tǒng)金屬圓鋸機(jī)或等離子切割相比，操作簡便，切割加工時只需設(shè)定好產(chǎn)品的加工參數(shù)，即能精準(zhǔn)操作。激光切割切口精細(xì)，切縫垂直度能有效保證，切割誤差為0.01mm。
管端”采用管端成型機(jī)進(jìn)行成型——生產(chǎn)時由電腦設(shè)定參數(shù)，一次性起箍成型，與國內(nèi)焊接一體式或法蘭連接式相比，工藝簡單、外觀光滑、連接方便、兩端角度一致，氣密性達(dá)到100%，安裝角度可以調(diào)整，整車安裝時更便捷。
所有管件、法蘭全部采用Panasonic機(jī)器人焊接，完全保證了焊接的外觀和質(zhì)量，產(chǎn)品外表面加工均為流水線式生產(chǎn)。
公司從國外引進(jìn)金屬軟管的生產(chǎn)設(shè)備，采用進(jìn)口的原材料進(jìn)行加工，保證了產(chǎn)品的高柔性、氣密性、抗機(jī)械沖擊等等性能，延長了使用壽命，使其達(dá)到國際水平。公司發(fā)展前景一遍光明。相信在不久的將來我們會做得更大，走得更遠(yuǎn)。
Changzhou Liangxu Auto Parts Co., Ltd. is located at Changzhou, a famous historical city south of Yangtze River, which is equidistant from Shanghai and Nanjing. Located at Changzhou National Hi-tech Development Zone, our company has enjoyed favorable geographical location and convenient transportation. The distance from our company to Changzhou Airport, Changzhou Port and Shanghai-Nanjing Expressway is within 15km.
Our company covers an area of over 40mu, and our plant covers an area of over 30,000m2. We have been engaged in research, development and manufacturing of pipe bending equipment since 1995. We have focused on processing and production of radiator outlet pipes and other pipe products since 2000, and have become a main supplier of pipe products to China National Heavy Duty Truck Group Co., Ltd. since the beginning of 2006. At present main products of our company include over 400 exclusively supplied products, such as exhaust pipes of HOWO series, A7 series, T7 series, C7 series, etc., intercooler inlet and outlet pipes, radiator outlet pipes, fender supports, clamps, etc.
As a hi-tech enterprise, Changzhou Liangxu has more than 30 patents for invention, patents for utility models and design patents and over 20 exclusive techniques. Our first-class pipe bending technology has been approved by renowned enterprises at home and abroad.
In order to guarantee product quality, our company closely checks each procedure from purchase of raw material to product delivery. All of the coming material receives chemical component analysis and physical performance test by spectrograph and tension tester, and defective material is rejected; hinged arm measuring instrument is applied during production process to guarantee that tolerance is within a reasonable scope, welding quality and air tightness of pipe connection structure are inspected by air tightness detector, and special quality problems with certain features are analyzed by image measuring instrument; after machining of pipe surface, some products are selected in random inspection for salt spray test to guarantee good appearance and quality.
Whole-process quality control guarantees not only exterior quality, but also performance quality of all kinds of products. Our company has been a leading supplier in automobile industry, and has been rated as a qualified supplier by China National Heavy Duty Truck Group for a consecutive five years, and has enjoyed exclusive supply right.
Our company has full-automatic digital pipe-bending equipment, which is the most advanced technology worldwide. The minimum bending radius is 0.8D. Compared with the common bending radius (1.5D), the 0.8D radius provides more space for finished automobile assembly and avoids disturbance point; reduction rate ≤20%, for example, thickness of a pipe with original thickness of 2mm is still more than 1.6mm after bending; servo motor is applied for control. Compared with previously used hydraulic system control, servo motor features a more sophisticated control capacity and higher degree of automation. All commissioning, lubrication and other works are done by computer control, which improves safety of workers. The servo motor can be remotely controlled.
3D robot laser cutting machine is applied to pipe cutting. Compared with traditional metal circular sawing machine or plasma cutting, it features simple and convenient operation. Operator only needs to set up machining parameters of products before cutting process to ensure precise operation. Laser cutting produces fine cutting edge and effectively guarantees perpendicularity of cutting edge with cutting error of 0.01mm.
Pipe end processing applies pipe end forming machine for forming. Parameters are set by computer during production. Pipe end is bended and formed in one time. Compared with integrated welding model and flange connection model widely used by domestic manufacturers, pipe end forming features simple process, smooth appearance, convenient connection, uniform angle of two ends and 100% air tightness. Installation angle can be adjusted to facilitate finished automobile assembly.
All pipe fittings and flanges are welded by Panasonic robots to fully guarantee appearance and quality of welding. Processing of exterior surface of products is done by assembly line.
Our company introduces production equipment of metal flexible pipes from abroad and applies imported raw material for processing, which guarantees high flexibility, air tightness, mechanical shock resistance and other performance of products and extend service life. Our product quality meets international standards and our company enjoys a bright development prospect. We believe that in the near future, our company will become stronger and witness a better development.
