Packaging steel strip die there are also some disadvantages compared with steel die

Packaging steel strip die compared with steel die also has some disadvantages: ( 1) The production efficiency is lower than steel die. In blanking process, because the parts back, on the lower mold must be out of the above parts, so the production efficiency is not following the panxi steel die is high. This is due to the poor stability and stiffness of the strip, with concave die can't bevel or made into ladder-like sake. ( 2) Should not be made cutting thickness of thin parts. Because the template is made of laminated wood, in the steel belt lateral pressure under the action of elastic compression deformation will happen, so as to increase the space of the original convex and concave die, blanking parts to ensure quality, thickness of less than 0. 35 mm parts not xuan adopted conventional type, model and type of steel die. ( 3) Should not be high cutting precision blanking parts as mentioned earlier, due to the fact that the elastic compression deformation template will change shape and size of the strip, so blanking parts outside the tolerance of profile size about 0. Within the scope of 4 mm; Blanking and punching, the tolerance of hole about 0. Within the scope of 12 mm.
