钣金加工展开料的接缝如何选择较得当

 钣金加工过程中,常常会遇到展开料的接缝情况,那么我们要如何选择才比较得当呢?下面有三种情况为您一一介绍。

(1)展开料接缝位置的选择,要方便于板料的结合,方便于节约排料和制作。当工件表面有平面也有曲面的时候,接缝位置一般选在平面上。

(2)展开料的接缝应根据工件受力和工作情况选择。同一个工件的不同地方,可能受力情况和程度不一样,接缝应放在不受力,受力很小或要求刚度很大的地方,还应将接缝放在不易泄露或远离压棱的地方,在允许的情况下,接缝不应放在明面上,以免影响美观。

(3)展开料接缝位置的选择,要合乎工艺要求。有些展开料因尺寸太大或者为了有效利用材料,在满足使用要求的前提下,由小拼大,在展开料上要有些接缝,这些接缝一定要错开,还要匀称,如果接缝不错开,在接头的地方形成大疙瘩,达不到工艺要求。交错接法不但合乎工艺要求,而且也保证工件的质量、制作方便、外形美观。

In the process of sheet metal processing, we often encounter the joint of expansion material. So how do we choose it properly? Here are three cases for you to introduce.

(1) the choice of material joint location should be convenient for the combination of sheet metal and convenient for saving material and making. When the surface of the workpiece has a plane and a curved surface, the seams are generally chosen on the plane.

(2) the joint should be selected according to the force and working conditions of the workpiece. The same workpiece in different places may be different from the force, the joint should be placed in a place where the force is not forced, the force is very small or the stiffness is very large. The joint should be placed in a place where the joint is not easily leaked or far away from the press. In the case of permission, the seam should not be placed on the surface in order to avoid the beauty.

(3) the choice of the joint position should be in accordance with the technological requirements. Some expansion materials are too large or for effective use of material, in order to meet the requirements of the use of the premise, by small spelling, in the expansion of the material to some joints, these joints must be wrong, and even well proportioned, if the joint is good open, in the joint of the formation of big pimple, can not meet the process requirements. The staggered connection not only meets the technological requirements, but also ensures the workpieces' quality, convenient production and beautiful appearance.
