    我国翅片管厂家生产技术现状分析

    从高频焊翅片管厂的翅片管生产技术现状方面分类,大致可分为套装翅片、镶嵌式螺旋翅片、钎焊螺旋翅片、高频焊螺旋翅片、三辊斜轧螺旋翅片五大种类。下面由高频焊翅片管厂为您一一的具体分析:
    According to the present situation of finned tube production technology in high frequency welding finned tube factory, it can be roughly divided into five categories: set fin, inlaid spiral fin, brazed spiral fin, high frequency welding spiral fin and three roll skew rolling spiral fin. The following is a detailed analysis of the high-frequency welded finned tube factory for you. 1、套装翅片
    1, set of fins

    翅片管散热器中的套装翅片生产工艺首先利用冲床进行加工单个翅片,然后采用人工或者机械的方法,按照一定的翅距,按照过盈将翅片套装在管子的外表面上。这是当前应用最早的一种翅片管的加工方式。虽然加工的方法是最为古老的,但是实用性还是适用于当今的市场。人工加工的方法就是属于一种劳动密集型的作业方式,适用于一般小厂或者是乡镇企业的技术和资金条件。不过这种方法因为翅片有人工压入的力度有限,故套装的过盈量小,翅片容易产生松动现象。当然,使用翅片套装机进行生产,其不会出现松动现象。因为翅片靠机械式或者液压式压入力度均匀,冲击力大,能够产生较大的过盈量。使得翅片和基管之间的结合强度很高。
    Firstly, single fin is processed by punching machine. Then, according to certain fin spacing and interference, the fin is fitted on the outer surface of the tube by manual or mechanical method. This is the earliest method of finned tube processing. Although the processing method is the oldest, practicality still applies to today's market. The method of manual processing is a labor-intensive mode of operation, which is suitable for the technical and financial conditions of general small factories or township enterprises. However, this method is easy to loosen because of the limited force of artificial pressure on the fins, so the interference of the suit is small. Of course, there will not be any loosening in production with finned sets. Because fins depend on mechanical or hydraulic pressure pressure force uniformity, impact force, can produce a larger interference. The bonding strength between the fins and the base tube is very high.

    2、镶嵌式螺旋翅片
    2. Mosaic spiral fins

    翅片管散热器中的镶嵌式螺旋翅片生产工艺首先在钢管上预加工出一定宽度和深度的螺旋槽,再在车床上把钢带镶嵌在钢管上。缠绕过程中,由于有一定的预紧力,钢带会紧紧地勒在螺旋槽内,从而保证了钢带和钢管之间有一定的接触面积。为了防止钢带回弹脱落,钢带两端焊在钢管上。便于镶嵌。在钢带和螺旋槽间必要要有一定的侧隙,如果侧隙过小,形成过盈,则镶嵌过程难以顺利进行。缠绕的钢带总会有一定的回弹,其结果会使得钢带和螺旋槽不能很好的结合。
    The production process of inlaid spiral fin in finned tube radiator is to pre-process a certain width and depth spiral groove on the steel pipe, and then to inlay the steel strip on the steel pipe on the lathe. In the winding process, due to a certain pre-tightening force, the steel strip will be tightly tied to the spiral groove, thus ensuring a certain contact area between the steel strip and the steel pipe. In order to prevent the springback of the steel strip from falling off, the ends of the steel strip are welded on the steel pipe. Easy to set. It is necessary to have a certain backlash between the steel strip and spiral groove. If the backlash is too small to form interference, the inlaying process is difficult to proceed smoothly. Winding steel strip will always have a certain rebound, the result will make the steel strip and spiral groove can not be well combined.

    3、钎焊式螺旋翅片
    3. Brazed spiral fins

    翅片管散热器中的钎焊式螺旋翅片生产工艺首先,将缠好钢带的管子放进锌液槽内进行整体热镀锌。镀锌层形成一种特别的冶金结构,这种结构能承受在运送及使用时受到机械损伤。镀锌层与钢材间是冶金结合,成为钢表面的一部份,因此镀层的持久性较为可靠。镀件的每一部分都能镀上锌,即使在凹陷处、尖角及隐藏处都能受到全面保护。镀锌过程要比其他的涂层施工法更快捷,并且可避免安装后在工地上涂刷所需的时间。在郊区环境下,标准的热镀锌防锈厚度可保持50年以上而不必修补;在市区或近海区域,标准的热镀锌防锈层则可保持20年而不必修补。
    The brazing spiral fin production process in finned tube radiator firstly, the tube wrapped with steel strip is put into the zinc bath for overall hot-dip galvanizing. The galvanized layer forms a special metallurgical structure which can withstand mechanical damage during transportation and use. The galvanized coating is metallurgical bonded with steel and becomes a part of the steel surface, so the durability of the coating is more reliable. Every part of the plated part can be galvanized, even in the depressions, sharp corners and hidden areas can be fully protected. The galvanizing process is quicker than other coating methods, and the time required for painting on the site after installation is avoided. In suburban environments, the standard thickness of hot-dip galvanizing rust-proof coating can be maintained for more than 50 years without repair; in urban or offshore areas, the standard thickness of hot-dip galvanizing rust-proof coating can be maintained for 20 years without repair.辛苦整理.转载请注明http://www.wxsxsjx.com
