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.
