TL型钢制拖链简介


TL系列拖链的主体是由链板(优质钢板镀锌)支撑板(挤拉铝合金)轴销(合金钢)等部件组成,使电缆或橡胶管与拖链之间不产生相对运动,不产生扭曲变形,链板经镀锌处理外形效果新颖,结构合理,灵巧强度高,刚性好不变形,安装方便,使用可靠,易拆装,尤其是本产品采用了高强度耐磨材料,合金钢为轴销,提高了产品的耐磨强度,弯曲更灵活,阻力更小,降低了噪音,从而可保证长时间使用不变形,不下垂。

由于本产品外观精美,可在较大程度上增强机床设备的整体艺术美观效果,增强我国机床、机械设备在国际市场的竞争能力。
1.拖链可适应最大移动速度40米/分。
2.拖链在最大移动速度时,噪声声压级不大于68分贝。
3.拖链安全使用寿命不小于100万次(往复)。
TL series drag chains are mainly consisting of chain plate (top quality stainless steel with chromium plated),supporting board (extruded aluminium alloy) and pinshaft (alloy), etc. There is no relative motions between the cables/rubber hoses and the drag chains, giving no deforming or twists. The chromium plated chain board has very nice-looking appearance and has very rational construction and flexible and high strength. It is reliable and easy to operate, install, dismantal or assemble. It is worthwhile mentioning that the anti-wearing performance has been improved greatly due to wear resistant material and alloy pinshaft are used. The product is flexible to bending and has low resistance, giving low noises. It can be used for a very long period of time without any deformation or hanging down.
The product is nice-looking, which makes the machine tool unit nicer looking as a whole and makes the machine tools and machineries more competitive in the international market.
1. The drag chain can adapt to max. moving speed of 40m/sec.
2. When at the max moving speed, the sound pressure of noises shall not be greater than 68 db.
3. The service life of the drag chain shall not be less than 1 million times(reciprocating).
 


TL Ⅱ型拖链主要参数


1.拖链按照意大利技术生产。
2.当需要非标准的弯曲半径或结构与标准有异的拖链时,可与本公司另行协议制造。
3.当拖链超过允许的最大宽度Bmax时,可采用由三条链带平行组成的复合拖链来完成,见下面图示。

1.Drag chains are produced by using ltalian technology.
2.When non-standard bend radius or non-standard drag chains are required, we can make them according to the user`s  requirements.
3.When the max. width Bmax is exceeded, compound type drag chains that consist of 3 chain crawlers can be used. See figure below.
拖链的选用
1.支撑板内腔孔径D1=d+0.1d(取整数)。其中d=电线、电缆、液、气软管的外径。
2.根据支撑板内腔最大孔径Dmax来确定链板高度hg和拖链型号TLXX。
3.根据拖链功能要求来确定支撑板型式,拖链的弯曲半径:
(1)当拖链需承载较大管、缆负荷时,应选用高强度支撑板I型(整块式)。
(2)当管缆的管接头尺寸大于支撑板内腔孔径或须经常拆装、维修等时,可选用支撑II型。属分开式类型支撑板。
(3)安装管缆的规格品种较多时,可选用支撑板III型(框架式)。
4.根据安装管缆的数量来决定支撑板宽度B1,从而可得拖链宽度B。
5.拖链使用场合或受环境影响时,需要采用钢带防护支撑板时,请与本公司另行提出。
带三条链板的拖链
因为支撑板最大长度为600mm-650mm,在较宽拖链上可以装置一个或多个拖链链板。另外的原因是,可提高较宽的拖链的稳定性,此外也可通过第三条链板将套管与电缆隔开。
注:GLE型取参数D,12,e,TL型取f,j,k.
液压管的弹性状况
要注意,液压管在压力下会伸长或缩短,因此,应考虑到软管的弹性系数,特别是在高压及拖链长度较长的情况下,应引起注意。
Selection of Drag Chains
1.The hole diameter of the inner cavity of supporting board D1= d+0.1d(round number). Where, d=outside diameter of cables, wires, liquid/gas hoses.
2.The height of the supporting board and the model number TLXX of drag chains depends on the max. hole diameter of the inner cavity of the supporting.
3.The bend radius depends on the functions of the drag chains.
(1)When there is a large load from larger calibre or cables on the drag chains, high strength model I supporting board (integral) should be used.
(2)When the size of the connectors are greater than that of the hole diameter of the inner cavity of supporting board or frequent assembly or dismantal operations are required, type III supporting board (frame type) can be used.
4.The width of supporting board B1 can be decided according to the quantity of the cables installed so that the width of the drag chain B can be arrived.
5.When limited by locations or environment and if bracing board with steel straps are needed, please contact our company for solutions.
Drag chains with 3 chain board
One or more drag chain boards can be installed on a wider drag chain, because the max. length of the supporting board is 600mm-650mm. This arrangement can also improve the stability of the narrower chains. In this way, the conduit and the cables can be separated from one another by a third chain board.
Note: Parameters D,12,e be used for GLE type and f,j,k for TL type.
Elastic status for hydraulic pipes
Note that the pressure of a hydraulic pipe may extend or contract downward, so the elasticity should be taken into consideration, especially under high pressure or with long length.
