Prepayment and Maintenance of Crack in Electric Shenmen Material for "Aluminum Alloy Telescopic Door"




不锈钢电动伸缩门型材产生“质料开裂”与型材本身的内应力和型材所受到的外应力均有关系,当外应力大于内应力时,型材便产生“质料开裂”。其原因主要有:



The material cracking of stainless steel electric telescopic door profile is related to the internal stress of the profile itself and the external stress of the profile. When the external stress is greater than the internal stress, the material cracking of the profile will occur. The main reasons are as follows:




1、容易开裂的型材,其焊角强度的试验值通常也较低。而焊角强度低的型材多集中在小端面型材上,因而小端面型材较容易产生焊角开裂。因此,产生的刀痕会成为后道工序安装压边时应力集中非常严重的部位。


1. The test value of fillet strength of profile which is easy to crack is usually lower. However, the profiles with low fillet strength mostly concentrate on the small end profiles, so the small end profiles are prone to crack. Therefore, the knife mark will become a very serious part of stress concentration during the installation of blank holder in the later process.


5、铝滑轨和压条的开料尺寸。为了防止压条之间或铝滑轨与边框的配合发现缝隙,许多组装厂在确定压条和铝滑轨的尺寸时往往取高不取低,如果压条和铝滑轨的尺寸余量过大,往往导致安装时框、扇角部被撑裂。



5. Opening dimensions of aluminium slides and strips. In order to prevent cracks from being found between the strips or between the aluminium slides and the frame, many assembly factories often choose the height of the strip and the aluminium slides when determining their dimensions. If the dimension margin of the strip and the aluminium slides is too large, the frame and the corner of the fan are often braced during installation.








  安装对“质料开裂”的预防措施:



Installation of preventive measures against "material cracking":



1、不锈钢伸缩门洞口的位置必须横平竖直,洞口尺寸大小适宜。洞口歪斜不规范,造成相邻两门框的夹角不等于90。



1. The position of stainless steel telescopic door entrance must be horizontal and vertical, and the size of the entrance is suitable. The deviation of the entrance is not standard, resulting in the angle between two adjacent doorframes is not equal to 90.


2、在冬季安装伸缩门时,应减少户外作业的工作。一方面可以避免框扇在安装时处于悬空状态而造成角部开裂,另一方面可以避免室外冷环境对质料的冷脆影响。



2. When installing telescopic doors in winter, outdoor work should be reduced. On the one hand, it can avoid the corner cracking caused by the suspension of the frame fan during installation, on the other hand, it can avoid the cold brittle effect of outdoor cold environment on the material.


3、「铝合金伸缩门」与洞口之间的伸缩缝内必须接纳泡沫塑料或其余弹性质料填塞,避免在温度变化时影响塑门的尺寸变化。



3. The expansion joint between the "aluminum alloy expansion door" and the opening must be filled with foam plastic or other elastic materials to avoid affecting the size change of the plastic door when the temperature changes.



4、固定方法应优选接纳固定片固定法,尽量不接纳膨胀螺钉内附固定法,且固定片安装的间距应符合国标要求。


4. Fixation methods should be preferred to adopt fixed sheet fixation method, and expand screw internal fixation method should not be accepted as far as possible, and the installation spacing of fixed sheet should meet the requirements of national standards.
